Anna tore away the wrapping paper and remembered to fake a smile as Aunt Wendy and Anna’s uncle looked on in happy expectation.

“Oh wow!” She gushed, desperately trying to make her face echo their excited happiness, “Leggings! For the gym! Thanks you guys!”

“That’s great! We thought that, what with your mother setting the example - I mean, talk about gains, I’m so jealous - and you already following in her footsteps... well, we thought it would be perfect!”

Anna smiles again to cover up the wince at ‘following in her footsteps’ - her mom, had moved up from ‘built’ to ‘incredibly built’ this year, but Anna had not even so much as lifted a weight.

And yet here she was, glowing with health, in baggy exercise sweats that hid everything apart from toned, strong-looking forearms.

Between her, her mom and her aunt, the front room looked like a fitness competition or bodybuilding show.

“Uh,” began Anna’s aunt carefully, and Anna’s belly felt like it had fallen out of her ass when she saw the hopeful expression, “can you try them on? I just want to make sure I got the size right - you need to look good for the ‘gram!”

Anna froze and smiled again. She wanted to punch something, but it was nice to enjoy a birthday with family. She didn’t want to spoil the day.

“Ah-“ she started, but stopped as her mother’s gently commanding voice cut across hers.

“I’m sure they’ll be fine,” Anna’s mom said, then changed the subject, “I’ve booked a special treat for Anna today - I was hoping we could grab some food and then Wendy could join me and Anna for the afternoon. Is that ok?”

Anna’s uncle seemed quite receptive and Anna remembered it was a big game in the football calendar this year. She could almost see him making up a list of where to watch it and what to eat as Aunt Wendy chatted through the afternoon plan with Anna’s mom.

“Put them on.”

Anna’s mom stood by the door to Anna’s room, her expression calm, her broad physique filling the doorway.

In the cramped clutter of the room Anna had grown up in, with old teen idol posters up on the wall, it seemed that her mom took up half the space.

“Mom! I’m a frickin’ adult for-“

“Put them on,” it was an order, as certain as day meets night.

Anna turned and looked at the cream coloured leggings, adorned with darts of pink at hip and ankle and large panels of stretchy mesh, as they lay small and shrivelled up on the bed.

She clenched her first and felt her forearms bulge as she thought about defying her mother, but she caught a tiny, almost imperceptible movement: her mom’s eyes widening and nostrils flaring in pleasure at the suggestion of a challenge.

The Game had started.

Anna gulped and let her hands open up, raising them only high enough to desultorily hook her thumbs in the waistband of her sweats and pause.

Playing the Game was... weird. It was about limits. Weird limits. And the heart of the Game was Anna.

“You either have to cum before I get your sweatpants off,” her mom said, “or you’re not allowed to cum until you get those leggings on.”

Anna gawped. There was no way, that was ridiculous.

Even as she hesitated, her mother took one huge step across the room and lunged forward, grabbing fistfuls of pant and underpants alike and yanking them down, leaving Anna naked from the waist down.

Exposing the reason the Game existed.

Anna had a cock. And not just any cock, but a huge, sense-defying monster that looked like it killed vaginas for fun. If that fucker had been green, the Hulk would have felt pretty awesome about having a monster cock like that swinging between his thighs.

As it was, the huge dong, finally freed from painful confinement, was happy drawing little lines of precum across the backs of Anna’s calves. It was brutish, massive, veiny and grotesque... and amazing.

“One point to me,” her mother growled, taking the huge meat in two strong hands and beginning to jack it roughly, “now, if you cum before you pull the leggings up, you’re giving me a triple shot tonight... hmmm you’re gonna give me sooo much juice!”

Anna moaned at the thought of what that would mean, how that could end up, and stooped quickly to grab at the leggings, trying to jam a foot into one of the leg holes before the inevitable happened.

/////

The first time Anna’s mom had taken Anna’s cock in her mouth, it had taken three hours of patient, deliberate stretching and lubrication. Now, it was fast enough to feel like an assault, as the telltale click of jaw muscle signalled the immense, fat, flared rim of Anna’s cock passing her mom’s molars and pressing down into a throat that looked like it could mangle anything foolhardy enough to enter it.

Instead, with a lunge of her head, Anna’s mom seemed instead to swallow, snake-like, a lump that would put a full-sized fire extinguisher to shame. The corded muscles, tendons and squirming veins of Anna’s mom’s neck were bloated outwards on a tide of sinking cockmeat and darkened to a deep red-purple colour as Anna’s quickly hardening cock was pushed, sucked and swallowed deeper and deeper.

Anna groaned as her mother’s strong hands clamped down on her stiffening crotchmonster and physically crammed dickmeat into that straining, stretched out mouth, driving Anna’s enormous glans down further and further and pulling Anna off-balance, thwarting Anna’s efforts to get the stupid leggings on for a moment.

The feeling of warm, wet throat around Anna’s cock was incredible, even more so when she felt the slit of her dickhead pushing at another orifice deep inside her mom... she was in her mom’s mouth as far as any human could have possibly taken her.

“GGGLLLRRRRUUHHHNNHHHH!”

The noise Anna’s mom made as her head changed direction and jerked away from Anna’s hips was gross: somewhere between a needy moan and a gooey, saliva-smeared barf of prize futa dick. The inches emerged from Anna’s mom’s mouth in a dusky pink waterfall of monstercock until the thick rim of Anna’s cockhead thumped into the backs of her mom’s molars, stopping the cock from flopping free of that hungry mouth.

Anna hooked a foot into one side of the leggings and pulled up desperately, her cock long enough to let her hop briefly and try and kick the other foot into the other leg hole on the way down.

In a miracle of coordination, she felt her other foot slide home. Then all she had to do was -

“HHHHHRRLLLLLGGLLLLGGLLLLGGLLLLL!”

Anna’s mom had never lost her grip on the huge cock, and now Anna had front row seats as thick, strong arms flexed into life and overpowered her mom’s reddened, straining throat once more. Cock seemed to flow into Anna’s mom’a neck and chest in great jerks as every internal obstacle was beaten away by the insistent power of those beefy arms.

Anna felt her huge, overtaxed nuts tighten as the tip of her cock hit the sphincter at the top of her mom’s stomach again, and she frantically scrambled to pull up the leggings while her mother was preoccupied. All it would take is a little jerk of her hips when her mom was nearly entirely off that cock and she would be free to pull the leggings up the rest of the way and win - she just had to wait it out.

She wasn’t prepared to feel the growl of pure willpower that thrummed through her mom’s body and up the massive shaft of her cock... and she wasn’t prepared to feel the pressure on her cockhead increase further and further.

Anna groaned as she felt the blunt tip of her cock slowly forcing open the entrance to her mom’s stomach. It felt amaz-

She grit her teeth and her legs trembled as she resisted the urge to give in and use her own ass muscles and strong legs to push more of her cock into her mom.

Then Anna’s mom tensed and began rocking almost imperceptibly back and forth, using the ring of her stomach sphincter to micro-fuck Anna’s huge, bloated cockhead. It was like being sucked off by a mouth inside a throat inside a mouth... and it was gooooood.

Anna groaned and bit her lip as her hands scrabbled desperately, hauling the waistband of her leggings up over her butt, the elasticated waist stretching hugely as at the front it was trapped beneath her increasingly massive, churning balls.

She just needed to hold out a bit longer and pick her moment. She couldn’t give her mom a triple shot... just two big shots had been enough juice to make her mom pack on 30 pounds of muscle.

She looked down.

And into the blissed out gaze of her own mother as the bigger woman leaned in, pecs dancing as chest muscles fluttered and flexed around the invading meat. The eye contact spoke volumes about lust and desperation, and pure, mind-altering sensation.

Anna squeezed her eyes shut and tried to pull free, but her mom quickly responded by dropping her hands down to Anna’s balls and fondling them, squeezing them, letting drool spatter down onto them and rub it into that straining sack.

Then Anna’s mom pushed her head forward, hard and insistent, and Anna could feel the rim of her glans nearly pop through the opening at the top of her mom’s stomach. It was... it was...

Anna whimpered in annoyance and defeat as she jerked her hips forward and fucked the head of her cock fully into her mom’s stomach, feeling her huge balls draw up tightly as a deluge of cum bloated out her cock and raced into her mom’s body. These weren’t spurts, or pulses, but a thundering tide of hot, churning jizz. The feeling as her cockslit stretched to accommodate, and began to vibrate with the sheer power of, the flood of cum into her mom’s belly was enough to kick Anna’s monster into high gear. Back arching, hands clapping together to hold her mom’s head, she could barely see as her eyes rolled back and another orgasm rose to roll over the first.

“MMMMNNNGGHHHLLL!”

Her mom was moaning and the strong hands that had been dominating Anna’s dick were now pressed to her thick muscular middle as it swelled further and further outwards, cobbled muscle stretching flatter and further as cum flooding into her mom’s stomach caused it to bloat and swell and grow.

The electric crackle of orgasm took an age to die away and even longer for the flood of cum - liquid, sloshing gallons of it - to finally come to a stop. Anna felt her back muscles relax and let herself slouch, all movement slowing and dying back.

She looked down.

Anna’s mom was looking up at her with clear, proud eyes, full lips still stretched hugely far around Anna’s immense girth.

“GGGHHHGGGHHRRRLLLKKKK!”

The sound of Anna’s mom finally giving in and coughing and gagging up Anna’s cock was hot, in a gross way, but it was like watching something out of a nature documentary. Like watching a boa constrictor spitting out an anaconda.

With a gentle tug and a gooey thump, Anna’s monster cock flopped out of her mom’s mouth and slammed down onto the fabric of Anna’s leggings, smearing spit and cum all over the material.

Anna’s mom smiled and reached up, strong hands stretching the waistband of the leggings as far as they would go and lifting Anna’s huge junk up to flop meaty shaft and heavy balls into the spandex.

The huge mass of dick and balls splatted into the stretchy pouch formed by the front of the leggings, the cut and fit far too moulded for feminine curves to allow much room. The spandex stretched and stretched and stretched, quickly soaking through with fresh, sloppy cum, the fabric lightening and growing sheer under the weight and pressure of Anna’s trouser snake.

It settled.

It settled.

It stopped, with a creak of straining elastic and the cool, clear air kissing over a foot of jizz-frosted monster song that looped massively up and over the waistband of the leggings, forced out by the sheer mass of remaining shaft and virile ballsack.

Anna wanted to scream, as she looked down at herself and at the smug, satisfied gaze of her mother.

It had never been a game she could win; she’d been tricked.

A traitorous thought crossed her mind as she watched her mother burp - a small waterfall of cum sluicing over full lips and chin to wash that thick, muscular chest - and the thought was... she’d liked it anyway.

Anna’s guilty joy was short lived though, as her mom gargled six short words at her:

“You owe me a triple shot.”

With insouciant slowness, Anna’s mom reached across to where her phone lay and brought it up to her ear, looking up at Anna and smugly licking cummy lips, stroking her belly. Her mom cleared her throat as the phone rang, until, “Hi, Wendy? I’m going to have to raincheck on this afternoon,” Anna’s mom said, her voice normal as cum shone on her chin, thick neck and heaving pecs, “yeah, something’s come up!”

When people thought of mutants, well, a lot of them thought of comic book heroes and circus freaks. The only problem with that was the fact that comics aren’t real and a lot of circus freaks didn’t have mutations so much as birth defects or disabilities.

If they thought about it harder then they might think of someone like Anna. Biology 101 was just one of her minors, but she’d had to sit real low and get real quiet when the subject of futanari or hermaphroditism had come up as an increasingly common mutation. Some people in the media were even calling these mutations dangerous - it didn’t pay to be too forthcoming about this stuff.

Anna wasn’t going to win a Nobel prize for her thoughts on biological science, but she was interested in her condition generally and occasionally read deeply into it - and she had a theory.

It wasn’t mutations like hers that were the most dangerous - it was mutations that lay dormant, like timebombs, waiting for certain conditions to be met before becoming obvious, or manifesting.

Because there were some timebombs you had to go a long, long way to set off, but when you did the blast was going to be huge.

Most girls would never find out that their mother had a mutation, because they didn’t have a dick, let alone a 20lb monstercock. Even if there were others out there like Anna, she doubted any of them would be fucked up enough, or have a mother horny enough, hot enough, muscular enough and narcissistic enough to start something like the Game. She didn’t think there were any other people who would even have considered trying to force a cockhead of Anna’s size and girth through her mom’s cervix, nor a mom that was so hungry for dick that she would try over and over again until the first glorious time that Anna’s monster meat had surged into her mom’s uterus.

And yet all of that and the timebomb would still not have gone off, their lives would not have continued to change, the Game would not have become a fraught, tense affair of panic and domination and almost uncontrollable lust.

No, this mutation timebomb would not be going off in Anna’s face if the packaging for her weight loss shake and her mother’s post-workout protein and steroid cocktail weren’t so incredibly similar. Nobody would have known about her mom’s mutation if Anna’s incredible, enormous sexual equipment didn’t rely on a hormonal mutant cocktail of its own.

Anna even suspected that life would have gone on as normal if a quirk of the shape of her cock and the position of her grunting, savagely fucking mother one day hadn’t meant that the slit at the top of Anna’s cock was pressed against her mother’s left Fallopian tube as it gushed forth gallon after gallon of hot, steaming jizz that had abnormally huge concentrations of testosterone and other steroid hormones in it. The first, accidental, “shot.”

Life would have been normal if her mother had woken up the next day pleasantly sore, well-fucked and bloated, internally tender from the fucking of a lifetime. But instead Anna’s mom had been practically glowing with energy, fresh, horny and, more importantly, noticeably bigger and more muscular after just one night of sleep... and then she’d hit the gym with a raw fury and Anna’s fate had been sealed there and then.

/////

The third quart-sized protein shake bottle thumped onto the countertop with a glop and slosh of thick protein drink. Anna’s mom didn’t let go of it, just moved her hand over the lid and gave it a tap.

“There’s three. Now it’s time to pay your forfeit.”

Anna gulped and looked at the sheer volume of shake she was going to have to drink. She swore she was going to look pregnant by the time she was done with all three.

She barely noticed her mother’s other hand caressing the still-swollen bulge of that cum filled muscular belly, until her mother gave her bloated middle another pat.

“Come on Anna, it’s not like I haven’t already had my protein shake... and more of it too! Just suck it up and drink the mix.”

Anna glanced at her naked mom’s swollen middle and gulped again, then sighed and reached over to pick up the first shake bottle. She closed her eyes and started drinking, chugging the thick, malty, earthy-tasting mixture with a facility that came of increasingly frequent practice.

She didn’t know her mom had moved until she felt those strong hands on her meat, pulling her immense, slumbering snake out of the ineffectual leggings and slowly beginning to work the shaft.

It was way too early for a shot, it took a good hour for her system to get ‘charged up’, if not more, and she let out a whimper of complaint about being used like this again, trying to turn her hips away from her mom.

“No fair darling, if you get a protein shake, so do I! And I know you’re good for more than just three more shots today!”

Anna still felt a little drained from their last escapade and even though she knew she could go a few more times, it still felt like too much, too soon.

She groaned into the spout of the bottle as she continued to drink and tried to pull out of her mom’s grip.

“Ok hun,” her mom growled irritably, “Game on: if you don’t cum before you finish all three bottles, I’ll leave you alone for a month.”

Anna cracked an eye open incredulously and looked at her mom - she was being serious.

“If you cum before you finish drinking your mix, I get to do anything I want with your big friend here for a week, including up to three shots a day.”

It seemed like too much of a trade off to be real. Anna wanted to just reject it, but that wouldn’t be in the spirit of the Game.

She looked at her mother as her cock was slowly jacked by those strong hands, and Anna steadily poured more and more shake into her throat. It was too good to be true, but the payoff could be huge.

But so could the cost.

But the freedom of a whole month... she’d be nearly normal again.

She nodded at her mom.

Then the world lurched as her mother dropped, banging down into a kneeling position only to hurriedly cram Anna’s dick into that hungry mouth. The speed at which Anna’s dickmeat disappeared into her mom was frightening, her mother’s mouth throat and chest offering a seemingly straight shot into the cum-bloated belly that still held a sloshing payload of cum from that morning.

With a grunt of effort from her mom, Anna felt the tip of her cock punch into her mom’s belly and into a sea of hot churning cum. Then Anna watched as her mom’s hands came up and gripped the muscular throat surrounding Anna’s shaft. It looked as if Anna’s mom was going to strangle herself, with Anna’s cock trapped deep inside that muscular body... and then Anna’s mom started moving her hands up and down her neck in a hard, insistent, pumping rhythm.

Anna straightened and any last softness in her trouser monster disappeared as it stiffened in sympathy, already beginning to throb.

Desperately Anna closed her eyes and tilted her head back, chugging as quickly as she could as her mom completely bypassed foreplay and titillation and set about milking Anna’s dick with quickly increasing speed and intensity. Anna swore she could feel the pressure of each of her mom’s fingers through the flesh of that muscular neck as the jerking action continued to speed up and increase in pressure.

The last dregs of the first shake bottle coated Anna’s mouth as she slammed the bottle down empty on the countertop... and opened her eyes to look for the second shake. She was feeling pretty full already.

“Ho- holy shit!” she gasped, her hips beginning to pump in sympathy with her mom’s furious jacked-up jerk-off.

With trembling hands Anna raised the shake to her lips and chugged once, then twice, then a third time, struggling to control every instinct that was screaming at her to just cum and reach release.

The fourth gulp of shake was harder, Anna’s belly was already full to the point where she was completely satiated. Then the next gulp came as she felt her knees knock together, her mother’s industrial-style milking enough to nearly make Anna go cross-eyed as she gripped the counter for support.

The fifth gulp and Anna was nearly a third of the way through the second quart.

She just needed to hold out, for a whole month of normality.

Another gulp... another.

She felt her mom’s grip shift and the rhythmic pressure and pleasure lessen as the two-handed assault became one-handed. Anna slumped against the counter and desperately took another gulp and another, spreading her legs to brace herself against the onslaught and stay upright.

She was nearly two-thirds of the way through her bottle when she felt something brush her swinging, swelling balls.

Another gulp.

Then two fingers pushed up into her tight, soaking wet little pussy and curled around... searching for-

Anna jerked as her mom found the hot-button; strong fingers massaging the magical intersection of Anna’s g-spot and prostate. The motion was every bit as mechanical and insistent as the hand jacking Anna’s dick and far, far more effective.

“...uhnk!” Anna’s throat seemed to trap her scream of pleasure, choke it off before she could get into full flow. She had to stop drinking the mix for a breath just to avoid inhaling the shake and succumbing to a coughing fit.

Her dick jerked, bloated and orgasm just seemed to suddenly be there, in full force as in under a second, a quart of her own ‘protein shake’ was blasted into her mom’s belly. Then another.

And another.

Anna jerked and flopped against the counter, her wide eyes, and opening and closing mouth, making her look like nothing more than a freshly landed fish gasping for air.

She tried to take another drink of the mix, plastic screeching against the stone counter instead as she nearly lost her balance and had to slam the bottle down, clinging onto it for dear life.

There was no way she could take another gulp while her mom was still working her-

Anna’s back arched as the unceasing, unflinching tempo her mother was setting continued - one abrupt, intense, surprise orgasm was suddenly swallowed by another. Anna’s cockhead seemed to throb like an outboard engine as blast after blast of cum tumbled and raced down her shaft.

It wasn’t stopping. Her mom wasn’t stopping. This was crazy. This was-

This-

“Oh- ohfuck... OH. FUUUUUCK!!!”

Anna screamed and bucked, curling up and trying to bring her head down low enough to tip the shake bottle and drink from the spout rather than use weak, shaking arms to pour the mix into her mouth.

“PLEASE! Oh, st-“ Anna howled, pawing at her shake-filled belly and bouncing tits as she came again, “PLEEEEAAAASSSE!”

Neither of them could tell if Anna’s scream was agony or ecstasy.

/////

Anna could already feel the mix doing its work and turbocharging her rapidly refilling balls as she let the third bottle of shake - empty now - topple onto the counter with a ‘thunk’.

There was a heavy slap as one of her mom’s strong hands came down onto the countertop and the bigger, muscular form of Anna’s mom rose, powered up by a red, veiny arm that was already seriously pumped.

And the reason why the arm trembled was swiftly explained as Anna’s mom straightened and gently pushed Anna back... using only her belly.

The skin of her mom’s was shiny, smooth and unblemished.... and bulging out at least three feet from her mom’s body, like a huge, fleshy beachball.

“I... urrmmpph-“ her mom said, interrupted only by a brief wave of cum surging out of her mouth and onto that enormous belly, spattering onto ripped pecs and perky implant tits, “I... win. Come on.”

Anna’s mom took Anna’s hand and turned ponderously, wobbling a bit as she led Anna out of the kitchen and downstairs... into the gym.

/////

Anna’s mom had been merciful in allowing Anna to ‘rest’ while the older woman worked out.

And ‘workout’ was barely even the word for the assault Anna’s mom had perpetrated on the gym equipment. It had been intense.

Bigger and bigger stacks of weight had lifted and then clanged back against the stops as exercises were done to failure over and over again. Barbells had been cranked up the weights until heavy, impressive weights had transitioned to unreal, bar-bending weight. Dumbbells had grown, bigger, chunkier, hiding hands and wrists in deeper and deeper canyons between fat black discs of weight.

Anna’s mom wasn’t gleaming, or glowing with sweat - she looked like she’d just stepped out of a sweat shower and not missed an inch of her powerful body, or the immense swollen belly that seemed to dominate it now.

Anna watched her mom now, red, pumped up and looking like a linebacker has swallowed a pregnant woman - her mom was walking slowly, sorely, over to the pec fly deck and every being on her body seemed to be on show, seemed to throb with life.

Anna’s mom sat on the bench tiredly and turned to point to Anna, then used the same commanding finger to point down at a spot between those muscular thighs, a spot hidden from Anna’s mom’s view by a huge belly.

The real workout was about to begin.

Anna was standing between her mom’s thighs in a heartbeat, no longer worried about the Game, no longer worried about overarching consequences, just focused on this imperious, gorgeous, powerful woman in front of her - the source of the sexual addiction that kept her returning to the Game.

Lewdly, Anna rubbed her cock up and down the shining dome of her mom’s cum-packed belly her hands finding and stroking the taut flesh as she licked her lips and dry-humped the pregnant-looking bulge. This was part of her fantasy, of seeing her own mom knocked up, that had led to that fateful day with her giant cock hosing the first, least potent, shot into her mother’s womb.

Anna took a step back, then another half-step, to allow her hardness to drop down, curved downwards slightly just from its own weight, and press the leaking tip of her freshly recovered dick against the muscle-flanked tightness of her mother’s hungry cunt.

Anna leaned in.

They both moaned, feeling flesh slowly war with flesh as the pressure increased. Anna’s mom nodded, wanting more of this nasty foreplay.

Anna shuffled her foot forward for purchase, and then slowly flexed her abs and ass, leaning the force of her own small muscles and body weight into the next push.

There was a fleshy, liquid noise and something seemed to part for Anna, her mom gritting her teeth and nodding her head frantically, encouraging her on.

Anna grabbed her mom’s huge thighs and pushed with her hips even as she pulled with her arms, toned, lithe muscle springing to life across her lean figure. There was slow, steady progress under enough force that Anna’s dick was starting to acquire a compound bend under the pressure. The only easement of the increasing discomfort for Anna was coming from the tiny gains in depth as her cockhead forced her mother’s fuckhole wider and wider.

Both of them gasped and moaned as the flared rim of Anna’s glans finally popped into her mother’s wet, drooling sex with a liquid squelching noise and a great queef of displaced air.

Then it was time for Anna’s workout.

Planting her feet, Anna let her cock of its metaphorical leash, pumping her hips harder and harder as her mom fucked back at her as best as possible. Inch after inch of progress was hard won and it took ten minutes of athletic thrusting to get from just inside to in deep.

Anna’s hair was stuck to her face and neck, wet and sweaty, as she slowly joined her mother in looking like somebody had just hosed her down. The shake mix was helping stave off the fatigue, give her the energy she needed to properly fuck her own mother and give her the finish she had won from Anna.

Anna’s mom had cum four times already, stiffening and shaking as she gave in to the sensation of being truly voted out by her daughter’s monster with every huge, long thrust. Anna’s mom came again the first, the twentieth and the fiftieth time Anna’s dick had began pummelling it’s way through the cervix, stretching it further and further and further until a second, deep, internal penetration had taken place and Anna found herself liberally pumping dickmeat and precum up into her mom’s womb.

And there was still a long way to go.

Anna didn’t remember grabbing her mom’s ankles and pressing them up and out to open up the way. She didn’t quite remember when her mom’s hands had left that immense belly and darted up to cover her mom’s mouth, preventing the hard fucking from pumping out just as much stomach-packing cum out of Anna’s mom as there was brutal dickmeat being pushed in up the other end.

Anna’s abs and hips and butt and thighs were burning, her arms and shoulder and chest too. She could feel the ache of lactic acid in her calves and air burning her lungs as she panted. It had taken twenty minutes just to get here, and she was far from done for tonight.

Anna’s gasps had become little growls of effort as she moved from just pounding her shaft further and further into her mother, to pushing in a directed manner, dropping her mom’s right leg and making sure to angle the thrusts as best she could.

“YES! YYESSSSS!! GIVE IT TO ME!” her mom’s voice rang out through the gym, on the brink of climax... again.

Then Anna found it.

An opening, beyond an opening, beyond and opening. It was tiny, never intended for more than a tiny egg to make its journey from a normal ovary to a normal womb.But normal was an idea that had died that afternoon for Anna, and she doubted it would ever be coming back.

Slowly, with the application of increasingly savage force, Anna’s snake pushed up into the opening of her mom’s left Fallopian tube and stretched it far, far beyond anything nature intended, or could have conceived of. It had to be this way. It had to be efficient, effective and with as little waste as possible.

Anna could feel her heavy balls were throbbing with their crazy hormone payload as her own biology turned workout shakes into a cocktail of wild super steroids. Her immense sack was bouncing off her mom’s thick, hard ass muscles as Anna finally sunk the whole mighty length of her cock in her mom’s body.

She was going to pump freaky jizz into her mom’s ovary and make her mom into a hornier, more hench, more cut and more dominant goddess than she already was... and that was just the effects she could guess at. Just that thought was enough.

Anna came so hard she nearly swallowed her tongue, and she blacked out for thirty seconds.

/////

“AAARRRRGGHHH! IT HURRRTTSSSS SOOO GOOOOOOOD!”

Those were the first words that penetrated the mental fog of a soul-shattering orgasm... and that was followed by the realisation that Anna was still jetting pints and pints of jizz into...

... a mountain of belly, lopsided slightly due to the odd position of Anna’s dick and the ovary it was inundating with sexual chemicals.

Every inch of her mother’s sex was going crazy, milking the jizz out of Anna’s monster even as the room was treated to the increasingly loud noise of skin audibly stretching.

“YES, YES! I CAN FEEL IT! MORE! MOOOOOORE!”

Anna’s dick obliged and her whole body shook like a leaf as she slumped against the huge wall of bloated belly and ground her cock in as hard a she could for the last few shots, keeping her mom speared on her vast meat.

She wasn’t prepared for the nearly feline yowl of lust and orgasm and hunger that split the air as her mother’s body arched off the bench. Nor for every muscle in her mom’s cunt to flex at once and expel every bit of Anna’s dick, pushing her away bodily and tipping her backwards to sit on the floor with a thump.

Then Anna noticed it.

The muscles that were flexed tight and thrumming with pleasure were visibly growing before Anna’s eyes. Each heartbeat was like a pulse across her mom’s entire body, only there was no retraction, or receding after each beat, just more mass to build upon. It had been like that the second time Anna’s mom had taken a shot from Anna, and it was why Anna’s mom had been working out so hard before: she had ripped as many muscle fibres a she could to make their repair as dramatic and powerful as possible.

The wall of belly flesh was also receding - protein being processed quickly and whisked off to the muscles that were screaming the loudest for it.

Anna felt her softening cock harden again as she watched her mother’s body writhe and flip through pounds and pounds of muscle packing onto her already sizeable frame. Anna’s mom might have passed for a wide-hipped buff guy before, when seen from the back at least, but now there was no doubt that she was yoked - big by the standards of both women and men.

And the size of her mom’s belly, at least compared to the shots that had gone before, suggested that there was much more to come.

“OOOH YEEESSSS... gonna be so YOKED!”

Anna blinked; her mom’s voice sounded richer, huskier and very, very sexy.

Anna’s mom stood ponderously and cradled her belly as she rose off the bench, grunting softly each time her body grew, her pussy positively gushing as the sensations drove her higher and higher towards climax again.

Trembling, upright, Anna’s mom towered over her daughter, letting go of her belly to spread growing arms wide. Slowly Anna’s mom lifted this arms higher and higher, up to shoulder height, then above. A turn of huge, thickening wrists and her mom’s attitude of glorious supplication end with the sharp click of knuckles as open hands clenched into mighty, trembling fists.

There was a moment of silence, with Anna’s mom naked, sweaty, huge, swollen-bellied and with arms raised as if to strike - her body was burnished in the golden light of the gym and Anna looked up at her in powerful awe. It felt like some kind of terrible, insane prophecy hovered in the musky air.

Then Anna’s mom punched down and inwards, body swiftly growing and surging outwards in all directions as she hissed in effort and pleasure as she flexed the most amazing most-muscular pose that Anna could even imagine. The hiss deepened into a growl as Anna’s mom’s chest thickened and deepened, as the huge belly shrank and shrank and shrank, seeming to fuel the explosive growth of muscle mass all over the older woman’s straining, reddening body.

“HHHHRRRNNNNGGGGGGHHHHH! YYESSSS! FUCKIN’ GROOOOOOW!”

Anna scooted back a little as a huge thigh seemed to ballon well past champion bodybuilder size and continued flaring forwards and outward as muscle heaved and grew and throbbed larger and larger. Veins rose in quick succession, seeming to lance across her mother’s huge body like lightning bolts, all seeming to converge, not at the heart, but at her mom’s cunt. Trapped between the overhang of a still-prodigious belly, the thick claw of Adonis belt and Anna’s mom’s incredible thighs, one might have expected the pussy flesh to have disappeared effectively. Instead it was growing with the rest of that incredible body, growing with every ounce of effort Anna’s mom could squeeze out of that most-muscular flex.

Anna watched as muscles that might have normally never been named outside a textbook surged to life amid the only source of lushness and outright femininity left on that enormous body. Meaty flesh that might normally have been called things like the bulbospongiosus, or deep transverse perineus bloated and grew, and flexed and grew, and brutally, threateningly... GREW. Crown among all of this growth was the clit, which went from the classic thumb-y nub most female steroid users ended up with, to a vast, bloated mass of super-sensitised sex flesh that was as long as a coke can... and at least an inch wider in girth.

It looked like female sexuality turned up to a hundred, and it was completely and utterly uncompromising. Anna watched as her mother reached around her heavy belly to grip her clit and begin jacking it one-handed, encouraging the previously relatively dainty nub to assume its full majesty as it hardened into a 7 inch long hugely chubby shaft that dominated the space at the top of her mom’s cuntal folds.

Anna was so hard right now.

Anna’s mom’s belly was still big, if not as hugely swollen as before, but she still jacked that swollen clit until her whole, muscular body rose up on tip-toes as she wildly and wantonly got herself off, uncaring if errant splashes of her juices sluiced down on Anna and matted down her sweat-slick hair further.

With a last grunt, Anna’s mom came hard, mustering the strength to step forward and loom over the smaller woman, eclipsing Anna in her muscular shadow and the under the eaves of her enormous faux-pregnant belly.

The fragrant musk of Anna’s mom’s juices gushed out in a torrent and soaked her daughter in sheet after voluminous, jetting sheet of squirt as the older woman rode her orgasm hard, growling depraved sexual promises down at Anna and made sure to completely cover her from head to toe, marking her forever.

“Yeah,” Anna’s mom sneered as she looked down at her daughter, leaning down to pinch Anna’s cheeks between her strong fingers and point Anna’s juice-glazed face up, forcing her to make eye contact, “that’s right... this is who I need you to be: covered in my juices, submissive, on the floor and totally willing to do anything to make me better, bigger, harder, more full of muscle and steroids and testosterone. You’re going to make me a beast, a bull... a fucking goddess. And you better believe I’m going to need a loving, slutty little whore like my darling daughter to fuck me like I deserve.”

“You think losing the Game today is bad? You think having to give me a triple shot is bad?” Anna’s mom asked as she held Anna’s gaze, standing and jacking her huge fatty of a clit again, “You don’t have any idea what’s going to happen before we play the Game again... but I think I do.”

Anna’s mom raised her other arm and flexed a huge bicep, easily over 20 inches around, and slowly licked it, sending herself over the edge as her jacking sped up and she made sure to squirt all over Anna again, turning her head away from her huge arm muscles to stare dominantly down at her daughter as cunt-juices washed away a look of shock and surprise.

“I think I know what’s going to happen, I can feel it inside me, waiting... and- and I WANT IT!”

Panting, finished and flushed, Anna’s mom gave her new improved leg muscles one last admiring stroke and thumped over to one of the machines, leaving Anna to pant in the aftermath of the deluge.

Anna’s mom didn’t see her daughter scrape fresh pussy juice off her chest and face and cram it greedily into her mouth... nor did she see the monstrous meat that Anna sported harden so much that the very flesh of the shaft grew shiny and dark with surging blood pressure.

/////

Anna lay on her back on the floor of the gym, bracketed by a huge pair of dumbbells, and grunted as her mother began to settle into place.

The workout had been going for an hour, but Anna’s mom had lasted thirty minutes before she’d decided that Anna’s enormous cock needed to be part of the routine. And there was no way Anna was going to argue.

It had started on the leg press, with Anna riding the rails trapped between her mother’s bulging thighs and the metal deck of the weight sled. Every rep saw hundreds of pounds of steel pushing Anna down, cock first, into her mom and the wall of that massive belly, and then her mom’s mighty legs pushing Anna - and the weights - away again. Power sets, high intensity and huge weights had tested Anna’s mom’s strength, and the sheer force of the weight of the sled against Anna’s back had tested Anna’s courage... but her mother’s strength had overcome all previous personal bests, and any danger to her daughter.

Anna had tried to cum, but her mother’s hand had found the base of Anna’s cock and clamped down, cutting off the flow until Anna subsided, heavy balls swollen.

Weighted chin-ups later on had been terrifying, satisfying and crazy; her mother’s huge bulk seeming to go up and down like a piston even as Anna’s beast-dick disappeared up into clenching, cumming pussy and emerged again. Anna had shuddered and felt a chill of fear every time her mom had completed a rep and dropped, the heavy plates attached to her mom’s hip harness brushing Anna’s huge balls as they sped past on the way down, her mom’s huge glutes mashing against Anna’s tits on the way down to crash against the root of Anna’s tireless, overstimulated dick.

Anna had trembled and tried to ram her cock home, firing off her load, but her mom had suddenly, violently flexed down all her muscles at once and overpowered the thick shaft, forcing Anna’s cum to back up into her now massive, bloated balls.

Then there had been power squats, calf raises, and even cable crunches, all with Anna’s ever-ready meat in pussy or mouth or ass.

Each time Anna wanted to cum inside her mom so badly she could nearly taste her own backed up jizz. Each time her balls would end up bigger, angrier and more achingly full.

And now there was this.

Anna’s mom grunted as she leaned back a bit to straighten up the way in deeper as Anna’s elephant-shaming dick punched through mature cervix under the pressure of Anna’s mom’s increased mass and power.

“YEAH!” Anna’s mom growled, in her huskier, richer voice, “Get that fucker in - nnnghh - DEEEEP!”

There was a jerk of progress as Anna’s mom grit her teeth and pounded her hips downward, hammering Anna’s cock into the roof of her womb and roughly stretching it. Her mom’s gorgeous face had gone beyond lean and strong, towards genuinely powerful, jaw muscles twitching visibly as she ground her teeth in pain and pleasure, full lips pulled back in a snarl, beautiful dark eyes squinted in concentration and lustful rage.

Anna had been able to angle her mom for the first shot, rolling a lighter, more compliant figure into a position where she could cram her cock deeper into that hidden opening which her mom craved so much. Now, her mom was in charge and, less experienced, was having trouble arching her body in a way that would allow Anna to deliver the second shot of the three promised.

Anna felt a grim delight at the frustration her mom was feeling.

“Fuck! COME ON!”

Anna’s mom seemed angrier, more aggressive, more easily frustrated than ever, and it didn’t take a genius to figure out a hormone cocktail like the one flowing through throes incredible veins might have side-effects. Anna bit her lip and drank it in though, feeling her mother flex around Anna’s cock, moving and trying to reposition herself the right way.

It sucked to not be able to get off that way you want, Anna thought to herself, enjoying this moment of turning tables.

“Fuck, fuck, fuck... DAMMIT!”

Anna’s mom hammered her fist into the gym floor in frustration, making it shake and causing one of the huge dumbbells to jump and bounce with a clatter. Pushing that massive body up with one arm, Anna’s mom roughly jerked her hips up and then down hard again, slam-fucking that giant dong up into herself and twisting desperately.

Closer, but not there yet.

Anna smirked and cradled her immensely swollen balls, comforting them as much as possible while her mom used her cock roughly.

Anna’s mom repeated the attempt over and over, setting up a brutal fucking rhythm that felt like it was shaking Anna apart, never quite finding the position needed for Anna’s cockhead to find the entrance to her mom’s mutant ovary.

BAM, BAM, BAM, BAM

Lust and frustration were painted clearly across Anna’s mom’s face as she fucked her daughter harder and harder, her huge body flinging sweat and a quickly brewing torrent of sex juices all over Anna’s body and the floor around her. That huge body and belly rocked and rose and fucked harder and harder, veins from an already harsh, intense pump growing bigger, crazier and hammering blood into muscle groups faster than any human had a right to.

“NGGGHH! OH- OH!” her mom growled as Anna felt the tip of her cock brush the opening her mom was trying to line up, felt it miss again, “OH SHIT!”

Anna could barely hold back a giggle at the sight, remembering her mom’s fevered words about winning the Game. Remembering the shock of being doused and marked so animalistically by a tide of gushing pussy juice. Right now she almost felt... high.

Anna felt a shiver go through her mom’s body, saw fear in those squinted, desperate eyes, and realised that all this effort was getting her mom off in the most insane way. Just being able to use Anna’s body like this was setting her mom’s libido on fire, aided and abetted by the huge, thick clit that had hardened and begun to slap against Anna’s belly with each harsh pump of muscular hips downwards.

“FUCKYOUFUCKYOUFUCKYOU!”

Her mom’s internal muscles shivered around Anna and time seemed to slow as she watched this huge, muscular woman give in to the sensations of a crashing, muscle-spasming climax. Defeated by her own clumsiness and almost uncontrollable lust, Anna’s mom stiffened and straightened, one hand darting down to grip and hurriedly jack off her fat, long clit, having to twist and reach around her enormous middle to do so.

Anna felt a familiar opening brush the head of her monstercock as her mother lost herself in a gushing, screaming orgasm. Then she felt it again.

“No Mom,” Anna growled, drunk on sex, twisted by it, “fuck YOU!”

Then Anna gathered all of her strength and hammered her hips up, hilting herself in her mom, huge nuts clapping into that incredible muscular ass as she sunk in the last couple of hand spans and felt her thrumming cockhead park up hard against the prized target her mom had failed to find over and over.

Anna felt her huge cock bloat with blood, forcing her mother to arch her back, forcing her mom to look up at the ceiling simply due to the steel-like curve of Anna’s dick. Anna’s nuts felt like they were on fire after half and hour of fucking and edging - and she knew where she was going to put every bit of her second shot.

*FFFFFSSSSSPPLOOOOSSHHHHH*

The sound of what felt like a gallon of cum in a lump the size of a basketball racing up Anna’s cock filled the room, followed by the grunt of surprise from Anna’s mom as her super-stuffed pussy, cervix, womb and Fallopian tube suddenly and massively stretched around the irresistible force of Anna’s first, giant spurt.

“OH- OH G- OHGODOHGODOHGOD!”

Anna’s mom was screaming, babbling and shaking as the sudden blast of jizz hammered into her ovary, followed by another and another. Anna’s pleasure was so intense that she could feel her tongue lolling out of her mouth, eyes wandering vaguely over the vast wall of flesh and sex that was her mother. A memory prodded her lust-addled mind as she grunted and reached beneath her balls to cup them, squeeze them, somehow able to jam an arm between her sweating body and her mom’s swiftly swelling bulk to do so.

The memory guided her fingers further south, making her trapped forearm muscles ache as she turned and bent her wrist, feeling the still-giant balls throbbing against it as they worked overtime. Her fingers found her dripping, sloppy pussy and pushed in, burrowing their way to her hidden hot button - frantically working her mutant prostate.

“STOP! OH GOOOODDDD! TOO- AAANNNGHHHH! RRRRRNNGHHH! TOO MUCH!”

Anna’s mom’s belly was bigger than ever before and her womb and ovary were packed so full of cum that they completely eclipsed her cum-filled belly now, forcing great spurts of second-hand jizz up out of Anna’s mom’s mouth and nose.

Then Anna’s fingers did what her mom’s had done a few hours ago... and Anna felt a second mind-smashing orgasm crash into the back of her first climax along with a rising tide of hot young cum.

Her mother’s belly suddenly surged forward with a stretching of flesh and her mom’ scream... and the world went dark and warm and the temperature of hot, animal sex as Anna disappeared beneath it.

/////

When Anna woke up, all but one of the lights in the gym were off or broken, and all around her was devastation. She realised she was lying in a wide slick of what could only be pussy juices, and rolled over, slowly pushing herself up to a sitting position. She winced as her huge softy slapped into the floor and looked around, guilty and afraid.

Her mouth opened to call out to her mom, when she heard something move in the gloom.

There was a tiny metallic clank and the creak of protesting metal. Anna slowly stood and stepped into the shadows, walking towards the sound.

She could hear breathing now, see a hint of movement, and then...

An enormous wall of muscle stepped out of the deepest shadow and into a chink of dark golden light.

It was a Anna’s mom, and Anna could tell the muscular behemoth was still, quite visibly, growing as she casually curled a huge squat bar, well over 400 pounds of weight testing the strength of the metal and making the metallic noises Anna was hearing.

Her mom’s form was ragged, sloppy, but not because of strain or fatigue, but rather a lack of focus, only a bare effort... even a degree of inattention.

“Come on... come on...” Anna could hear her mom whispering, her eyes vacant, internal, as her incredible arms casually curled weights that only the strongest people could even get up off the floor. With each repetition, no matter how uneven, Anna’s mom’s arms swelled and grew bigger, mightier... each massive limb was reaching the point where they were deeper from peak of bicep to belly of tricep than Anna’s thigh was long. It was difficult to tell in the dark, but Anna’s mom must have been nearly seven feet tall, an almost as wide - chest and arms and thick back scrunched up just to allow her hands to both grip the wide squat bar and lift with something like proper form.

Each rep, the bar bumped off a thick, stuffed muscle gut, smaller than the pregnant looking belly she had sported earlier, but still protruding, now heavily armoured in huge, thick abdominal muscle.

Anna’s mom was just... massive, dominating, imposing. And seemingly stuck, drifting off course and desperately, worriedly distracted.

It couldn’t end like this... Anna couldn’t let it. She... she needed it. Needed the freaky, dominant incest sex and the cruelty and love and lust. It was...

It was her world now. She accepted that. And now her mom had to accept that too.

“Having trouble there, mom?” Anna teased, feeling strangely light, almost drunk, “Being a bull-beast-goddess not living up to expectations?”

Her mom’s eyes flicked down to her, and she saw the muscles in her mom’s shoulders, neck and jaw tense, and grow as the huge woman ground her teeth.

“I was supposed to be your ‘whore’ right? Your... ‘slut’?” Anna idly stroked her own slowly thickening shaft, pumping the heavy flesh back and forth through her juice-slicked hands. The slit at the tip, freshly stretched from the deluge of cum that had recently hammered through it, gaped open and closed like the mouthing of a fish.

Her mom dropped the weight to the floor with a huge crash and stood shivering, looking down at Anna, staring at that majestic, impossible dick attached to her gorgeous daughter, watching precum begin to ooze again from the gaping slit.

Anna stepped forward, rose onto her tiptoes, and slapped her mom across the face.

“You won the Game! You’re supposed to be a fucking winner!” Anna jeered, winding up and delivering another slap to her towering, bewildered mother, “‘Deserve’? What the fuck do you deserve, you fucking crazy bitch?!”

“‘I wanna fuckin’ triple shot!’” Anna mocked, “Yeah, ‘winner’? How’s that going for you?”

There was a deep growl of displeasure and Anna could make out the faint impression of texture over the top of those huge muscles. They seemed to be twitching, shredded, covered in veins.

Anna heard the growl and shivered, defiant, aroused. She grabbed her huge cock and waved it, slamming the heavy flesh into her mom’s belly in a series of provocative, aggressive dick slaps. Thick ropes of precum laced the air around them and her mom’s massive mass.

“THIS big ole fucker IS the Game! It’s why your throat and pussy and asshole are so fucked out you could deepthroat my fucking leg! You want to win the Game?! You don’t even get it do you? DO YOU?!”

Anna’s mom‘s knuckles clicked and Anna could feel the air moving as already-huge muscles built and grew and throbbed with increasing speed and power. She was getting through, getting the dominant bitch to show her claws, to get angry - to let loose.

“You only get to have a submissive WHORE of a daughter if you’re enough of a fucking stud to keep her! To fuck her like nobody else can, to make her YOURS!” Anna screamed, “YOU WANT TO USE ME LIKE A CUMSLUT, THEN YOU’VE GOT TO FUCKING TAKE ME, MIND, BODY AND SOUL!!!”

“RRRAAARRRRRRGGGGGHHHHHH!!!”

Anna’s mom roared and it came out like the terrifying primal bellow of a tiger or a lion: reverberant and full of threat, challenge and anger.

Muscles bulged all over Anna’s mom’s body and it seemed like the bigger, older woman had ants under her skin as she flexed and pumped and jerked, huge slabs of brawn erupting as something dammed up inside her broke loose. Each movement was accompanied by a detonation of pure power and what must have been an epic war of raging hormones.

Bigger, fuller lips; a squarer, more muscular jaw; a smoothing of brow ridge; a filling out of head hair; a reduction and refinement of body hair; ultra-butched out slabs of chest beef twitching; implants rising as if on a tide of surging titflesh; nipples growing long and thick; Adonis belt thickening to sickening size; wider shoulders; wider hips; tighter ass; bigger ass... contradiction, mixing, refinement.

Anna’s mom took a step back and flexed everything she could, hunching over as a surge of rampant growth literally shook her body, vaulting her into the kind of territory reserved for cartoonish muscle and the wildest imaginings of 3D graphics.

Her voice was lower again, a red-wine contralto of unrestrained lust and rage, her breath coming in grunts as she bore down harder and harder into her flex.

“YES! YEEEEESSSSSSSS!!! MOOORRRREEEE!! I CAN FEEL IT COMING!”

Anna’s mom slowly, triumphantly, raised arms bigger than most men’s entire bodies - enormous, vascular, shredded muscles mashing into each other as she laced her fingers with a grunt and straightened, bringing her hips into the shaft of dim light.

Anna gasped.

Beside her mom’s frantic, feverish panting, Anna’s mom’s midriff was a squirming sea of movement as veins visibly throbbed and muscles still grew and twitched. At the heart of it all was the crazed, glorious mess of meat and muscle and sheer lust that was Anna’s mom’s sex, crowned in all it straining glory by that short, fat shaft of clit.

Anna’s mom groaned and flexed in a wave that seemed to ripple downwards starting from massive her raised arms. The wave thickened every inch of limb and torso it passed through, but it was Ann’s mom’s clit and pussy that seemed to simply inflate in response. Seven hugely girthy inches of clit became eight, ten, twelve. Anna could see the flare of a proper head and the slit in the tip form as Anna’s mom pumped her hips lewdly, wantonly. Twelve inches became fourteen as the base of the clit grew thicker and baggy.

But this wasn’t just a growth, or a bolt-on, this was a kind of appalling biological alchemy: Anna watched, stunned as two huge balls dropped into the baggy skin at the base of the shaft... then three more... then another and another. The wrinkly flesh grew tight around the huge payloads, shinier and shinier until Anna could swear three of the balls combined into one and the others merged likewise. The newly formed nutsack bulged obscenely, still growing in odd fits and starts at the base of what was increasingly now a cock and not a clit.

Anna’s mom’s face was locked in a sneer of arousal and arrogant pride as she continued to pump her hips, now obviously pumping them at Anna, her eyes locked on her daughter. At fourteen, fifteen and then sixteen inches in length the growth of the shaft outwards slowed and stopped, only for the girth to bloat outwards again and again and again, a combination of sheer mass and bigger, gnarlier veins contributing to the size of the thing.

Bigger than any pornstar could dream of, Anna’s mom sported a majestic log of shecock, garlanded by a ballsack bigger even than Anna’s own straining seed pods. Even against a straining, flexing, growing wall of muscle the new addition still looked big, potent and... addictive.

Anna stepped forwards, as if in a trance, her hands out as her giant mother watched, panting and still pumping her hips, fucking the shit out of the air as that prize shecock puked out increasingly thick, viscous loads of freaky mutant precum.

Anna didn’t even remember bending down, but suddenly all she could taste was her mother’s funky dick juice as Anna’s tongue found the slit and dipped inside, lapping up the heady liquid and feeling the tingle of it on her tongue, coating her teeth, warming her cheeks and throat. Something was happening and it felt amazing.

Anna’s eyes rolled up to see a big hand at the end of a torso-thick arm settle on her head, commanding, imperious. Barely visible above a landscape of flesh and shadow - a huge canyon between two massive, heaving tits and a pair of pectoral muscles that were at least six inches thick - Anna could see her mom’s hard, beautiful eyes gazing down at her like a predator eyeing prey.

Waiting.

Anna didn’t even stop her licking as she nodded and opened her mouth as wide as possible, a tiny opening in front of a giant invader.

“HHHHRRRRLLLKKKKKK!”

Anna’s face stung and she didn’t understand. Anna’s nose ached and she didn’t understand. Anna couldn’t swallow, couldn’t see and could barely breathe - she didn’t understand.

Anna’s eyes rolled back into her head and her feet drummed on the floor of the gym as she felt herself puking up something enormous. The dim light of the gym seemed super bright as Anna’s face was pushed back away from the cobbled, veiny immensity of her mom’s huge eightpack. To her confused eyes it looked like she had sucked her mom’s huge muscles down into her throat linking them by a dusky column of flesh that grew and grew as her face was pushed away.

Anna convulsed and coughed up a load of saliva as something tickled her throat and her gag reflex, then again, and again. Finally, something gave and a fleshy hard rim of something popped out of her throat and filled her mouth, making her jaw strain even wider as mommy-muscle scraped her teeth. With a last jerk of her head, completely controlled now by her mom’s strong hand, she came free with a gasp of air and a long, messy web of drool and saliva.

She stared cross-eyed at the thing that had just left her mouth: her mom’s enormous cock. Her lovely stud dick.

Anna’s new obsession. Her mom needed all the dick. That was Anna’s life now... making her mom bigger, better, perfect: a goddess.

“Yes! Yes! YES!” Anna breathed.

Anna opened her mouth wide and looked up at her mom’s hard, unblinking eyes. It was an invitation: Anna didn’t want to be herself anymore, she needed to be broken, taken, owned... and remade.

“Get ready for your protein mix... Slut,” her mom purred, voice as rich as chocolate, thrumming with sexual need.

“Yes Mommy!”

Anna watched her mother’s dick grow shiny with blood as it twitched at her words, seeming to radiate arousal.

“HHHRRKKK!” *SLAP*

“GGGGGLLRRKKK!” *SLAP*

It took two thrusts - Anna’s gagging, drool-smeared face mashed painfully into her mom’s unyielding abs each time, eyes watering - for the grip on Anna’s head to change and allow her forehead to bear the brunt of the skullfucking she was receiving.

“GGLLLCCHHLLL!” *BAM*

“HHHLLKKK!” *BAM*

“GGGGRRRGGLLL!!” *BAM*

There was a growl from above as Anna’s mom kicked into high gear, bringing her other hand down to cup Anna’s throat as massively powerful hips powered thick, fresh meat into Anna’s face faster and faster.

*BAMBAMBAMBAMBAMBAMBAMBAMBAMBAMBAMBAM*

Anna shuddered as she built to climax, screaming around her mom’s cock and using her free hands to jack her own monster, paying tribute to the massive body that was dominating hers. Her cock was throbbing in sympathy with the increasingly rapid face-fucking, as Anna’s mind seemed to melt under the assault and the repeated impacts of forehead off cobbled belly.

The world spun giddily with Anna’s mom’s dick buried to the hilt and it felt like Anna’s throat and head were going to be twisted off as Anna was lifted off the floor and turned upside down. She felt her monster get sandwiched between two walls of muscle and softness - probably her mom’s improbable pecs - and a freakishly long, strong, muscular tongue licking, washing, cradling her nuts as they throbbed with impending orgasm.

Anna’s mom’s strong hands returned to cradle Anna’s head, inhumanly thick powerful arms pinning Anna’s small, lean body against her mother’s as the face-fucking resumed.

Anna’s whole body weight was driving her face-first down her mom’s cock and it felt amazing to have that much meat in her mouth and neck, feeling the head pumping in and out of her chest on each of her mom’s powerful, muscular thrusts. The thing that put her over the edge was her mom’s freakishly huge balls bouncing off Anna’s face with every brutal thrust. Those churning, tight balls smashed into her nose and eyes and forehead as spit gushed out from her mouth only to, from her point of view at least, fall upwards towards the floor.

Her body stiffened and she bucked as the sheer lewdness if this moment in time fried her brain - she screamed around the cock dominating her face as she felt her cock lurch, seed erupting from her monster testicles to douse her mom’s body.

Anna’s orgasmic scream rose and rose into a howl as huge slabs of her mom’s chest muscle flexed into life and strangled the flood of cum at source, forcing her balls to churn and grow and back up with scorching loads of jizz. Anna’s mom didn’t pause in her own onslaught, fucking Anna’s mouth harder than ever even as orgasm was kept poised, just out of her daughter’s reach.

Anna could feel her brain twisting under the assault of her mom, the orgasm denial and the whap, whap, whap of heavy bulging ball meat bouncing off her spit-slicked face at the end of every thrust. It was like everything that wasn’t sexual, depraved and lewd was being battered out of her brain by repeated collisions with her mom’s huge nuts or sucked up into Anna’s swelling balls as her crimped-off cock throbbed and strained violently.

She shuddered as she came again, the orgasm a huge release that crashed headlong into painful pressure. Her mom’s tongue seemed to wrap entirely around one of Anna’s swollen, purpling testes and jack the churning cum factory in time with the pounding her her mom’s muscular hips.

It felt so good, and so bad, and so- so crazy to be here like this, giving herself like this, being used like this.

But it also felt deeply, increasingly, right.

Anna was licking, slurping, humming and moaning around the cock pounding her face, desperate for it to give up its prize. Her fingers found their way to her mom’s thumping, bulging ballsack and cupped the huge testes, feeling them overflow her small hands, mashing their hot, sweaty flesh into her face to mark herself with them, smear their musk into her skin as she drooled and gagged and coughed around the huge weapon stretching her throat.

“Nnnrrrggghh...” Anna’s mom growled, her hips suddenly speeding up as she reached a controlled, understated kind of climax, “Hmmmm, drink it all, Slut.”

Strong fingers pinched Anna’s nose shut as the cock inside her mouth and neck bloated under the pressure of a first, virgin cock orgasm for her mom.

“Oh- oh... yeeeeaahhhh,” her mom’s voice wasn’t so much heard as felt by Anna, the tone low, almost conversational, even as a gooey, funky torrent of cum thumped into Anna’s belly and quickly started stretching it.

As Anna’s rapidly filling belly pushed her away from the inverted clinch with her mom’s huge figure, Anna felt the cock in her throat struggling to keep her upright, straining the flesh of her chest and neck. A quick change of grip and her mom was letting Anna’s body drop to basically horizontal, facing upwards toward the ceiling and spitted through the mouth at one and while being squeezed and held up by the base of her cock on the other end.

Still Anna’s belly continued to rise and fill with curiously mobile, active jizz. She could almost feel it writhing around inside her.

“I’m going to cum again,” said Anna’s mom matter-of-factly, before the deluge into Anna’s belly redoubled. The huge nuts resting on Anna’s slobbery upturned face were bouncing and jerking even more now as they did their work.

Anna’s mom changed grip so that one might hand was crimping the base of Anna’s freak dick and the other was jacking the huge shaft with hard, powerful strokes that didn’t titillate so much as suction the arousal up Anna’s dick like her mom was using a bike pump; the urge to cum again was irresistible and-

“HHHMMMMNNNHHHH!”

Anna moaned loudly into her mom’s cock and ball sack as her mom’s mouth found and slid over the tip of Anna’s monster, that super long, wicked tongue finding the gaping slit in Anna’s cock and lewdly slithering down it. Anna’s eyes crossed as her back arched and she came again at the sensation, her tortured balls churning as she felt her orgasm smash into and be repelled by the huge fist gripping the base of her meat.

Mercifully the torrent into Anna’s belly was slowing down, her mom’s fresh load of jizz huge, pints and pints of the stuff but not the insane output that Anna had. Anna just looked nine months pregnant with triplets.

Anna’s mom’s tongue was doing a number down Anna’s cockpipe, thrusting deeper and deeper as her mom’s control improved, and Anna gave her mom a front row seat as she screamed into the base of her mom’s cock once more, the sound nearly drowning out the sound of her own cummy backwash as another orgasm was forced to rebound from her mom’s unstoppable grip.

“Huh...” Anna’s mom purred around Anna’s dick as she slowly watched her daughters ballsack inflate past the size of two basketballs, the flesh stretched and bloated with the tide of jizz many-times-denied and packed in densely.

The tongue was removed, and replaced by one finger in Anna’s cumslit, then two, then three. The sheer size of Anna’s monster dick and it’s recent heavy use had left the main vein stretched out and slack.

The world shifted and Anna felt her back touch the cool gym floor as she was laid down, the grip on her straining root never lessening, never easing up as her mother’s cock was dragged roughly from her throat, a last blast of jizz on the way out causing cum to rush into Anna’s sinuses and jet out of her nose. There was a change in grip, a movement of mass and muscle so huge it was like a looming pressure, and suddenly Anna was looking up over her grossly swollen tummy to see the immensity of her mom crouched above her.

“What are you for?” Anna’s mom asked.

Anna mewled weakly as her fried brain tried to understand the question, seeking out any part of her mom’s words that make sense. Anna just wanted to cum - hard. Her long was lolling out, tired and aching after trying to clean and tease her mom’s big dick. It tasted of cum. It smelt of cum. She needed to-

“CUM! CUUUUUUMMMM!”

“Yeah,” her mom purred, a smooth, rich rumble slipping her finger back down into Anna’s cockslit, “From now on, Slut, the only thing you are for is cum. If you’re not taking it, you’ll be making it... and there will be lots of it. And you’ll LOVE it.”

Anna didn’t know what that meant, didn’t know anything much right now apart from how her abused body felt. It felt...

Oddly good?

Her belly was brimming with her mom’s cum, the mixture of protein and hormones in it even freakier and more potent than the load Anna’s mutant dick had shot up into her an hour ago. Her body was processing this mix, blood fizzing as stretched and fucked out muscles healed, the tissues of her tortured dick and balls growing stronger, bigger, more resilient.

“I’m going to fuck you so full of cum by the time we’re done,” Anna’s mom said in that eerily controlled, commanding voice adding another finger to the one pumping in and out of Anna’s cockhead, “that you won’t remember not tasting it or smelling it. You’ll need it on you, in you, just to function. Every time you take a shot on your big fat tits just to stop shaking from withdrawal, you’ll remember that it’s because I want you this way, because I won.” Anna’s mom added a third finger and a fourth, starting to really stretch Anna’s dickpipe, “Because I will fuck every hole you have - and mark you as my Slut in places people can’t even IMAGINE.”

Anna’s eyes rolled as a twist of the wrist allowed Anna’s mom to tuck her thumb under her fingers and begin probing deeper into Anna’s monster with her now cone-shaped hand.

Anna had a moment to wonder woozily as she looked up past her modest B-cup boobs and grossly swollen belly to see her mom slowly push her knuckles in and start fisting Anna’s cock... where had ‘big fat tits’ come from?

Her mom’s hand slowly disappeared into Anna’s dick with a sensation that made Anna pant and drool with lust, her eyes rolling madly as she came again, and again her crazy huge balls tried to overpower her mom’s grip and failed. Her body fizzed and Anna felt her mind twist further as the pleasure-pain set her nerves on fire. She bit her lip and began working her hips, desperate for the paingasm to happen again, for her huge balls to get huger - chasing them increasingly addictive sensation.

“That’s it Slut,” Anna’s mom growled, her expression growing wilder, more intense, happier, as that hand pushed deeper into Anna’s monster dick in response, massively bulging forearm muscles stretching the cumslit wider and wider and wider, “use me to fuck yourself, break yourself... make yourself into the perfect Slut for your GODDESS!”

*SCHLUUUCCCKK*

The sound of Anna’s mom’s fist being roughly pulled out of Anna’s dick was disgustingly arousing, but nowhere near the nuclear-hot pleasure of the actual feeling. Anna came so hard that she arched almost her whole swollen body off the floor from her heels to the back of her neck.

And then her world changed again, forever.

/////

Anna’s mom had started the Game on the last day of high school, but Anna hadn’t really known that then.

They both new of Anna’s curious, massively overdeveloped genitals - it was no surprise, Anna’s mom was a devoted single parent - but Anna hadn’t known of her mom’s obsession with it, with her.

But that long summer together before college had been the first time Anna’s mom had tipped her hand. Anna had, during comfortable, familiar chats and unguarded moments come to understand that her mom thought of herself as a size queen - revelling in it a bit even. She worked out and grew strong to be as big as she could, to be dominant. Anna’s mom had even sheepishly confessed that her pregnancy with Anna had come about in a night of size-based passion, with a... person.

Anna’s father was never really mentioned in any detail: tall, short, white, black, latinx... even male or futa, was never really discussed. Anna suspected that there was a very hung dickgirl out there who had no idea she’d fathered a girl with a cock that could shame steroid-fed livestock.

The first clue about the mounting obsession was the shopping. Huge boxes that would arrive and never be opened in her sight, but were emblazoned with names and graphics that were a little suggestive: company names that were risqué sexual puns, angels, devils or divas that were drawn in pinup poses holding suggestively shaped logos. Then there were the simple things: a swede bought at the store, huge and juicy looking but never eaten or seen again, prize aubergines, even melons and watermelons that made it into the shopping basket but not the to the table.

Then there had been the first Game - one of many she had won in the beginning - and the bet had been simple: who could eat a whole honeydew melon the fastest?

Anna had, competitive and cunning, hurled the thing into a juicer and chugged the concoction quickly, desperately, watching wide-eyed as her mom opened her mouth further and further, looking at Anna with a burning, suggestive lust as the older woman simply began to push the whole thing into her mouth and throat in a demonstration of the benefits of months of practice. Anna had won that round, but her straining cock had taken hours of frantic, guilty jerking that night to finally soften from soul-twisting incestuous arousal.

Looking back, it was hard to say who had really won that night, after Anna had seen the literal fruit of months and months of her mom’s desperate sexual training and stretching.

/////

Anna’s mom’s dick was huge, as long as any cock she’d ever heard of - the 16 inch fake rubber ‘monsters’ in porn, the photos of sad looking men and futas from medical texts about hypertrophy - but it was also thick. Like the difference between a prom queen’s slender arm and a male bodybuilder’s. It would have scared off any woman or man who had never had two arms in their body up to the elbow... and even then it would have given them pause.

So the feeling as the head of her mom’s brand new dick slowly forced it’s way into Anna’s cock was... extreme.

“Hhhnngghh! I’m going to fuck your hungry little dick-pussy, Slut... I’m going to own it, mark it and make every inch of it - MMMHHNNGGHH - MINE!”

Anna’s mom crouched above Anna, the flare of her cockhead slowly pushing into Anna’s cockslit and bloating out the already huge mass of Anna’s own enormous glans. One strong arm, bulging with muscle, was blocking part of Anna’s view, the mighty hand at the end of it gripping the base of Anna’s cock with unshakeable strength. The other muscle-bound arm, equally huge in size came down to let a second hand join the first.

Then both arms flexed as Anna’s mom’s massive thighs exploded in size, that inhumanly muscled body dipping into a deep squat as Anna’s mom used all of her immense body weight and arm strength to pull herself deeper inch by arm-thick inch, until the whole of her new cock was sheathed in Anna’s monster dick meat. Anna’s heels were drumming on the floor as she thrashed and grabbed her pert tits, mashing them in her hands, tugging lewdly, painfully on her own nipples to add to the sensations.

“Fu- F- Fu- F-“ Anna’s words were choked off by sparking ecstasy and hyperventilation as she felt another walk come crashing down in her mind, the repressed, shameful lusts behind it pouring out, staining her mind and soul.

“FUCK MY MONSTER, MOMMY! KNOCK UP MY FILTHY JIZZ BAGS! DROWN! MY! CUUUUUMMMMMM!”

Her mom just chuckled and began to pull out, until the tips of their dicks nearly separated... and then all that muscle and strength drove her meat back into Anna’s monster again with a lewd fart of displaced air. Each thrust seemed to take a thousand years from start to finish, as Anna’s mind was acid-washed in pure sharp pleasure - she could describe what every millimetre felt like, even as her mom sped up faster and faster.

Anna came again the sixth time the flare of her mom’s glans had slipped, a little lopsidedly, into Anna’s cum pipe - the thick, veiny banjo-string roughly sawing over Anna’s stretched cumslit. Anna could have written a book about that moment.

The orgasm was massive, but as fruitless as any of Anna’s had been since her mom’s strength had forbidden her from ejaculating.

Twenty five strokes later Anna came again. And again at sixty three strokes. She came, painfully, eight times in eight stokes from the hundred and twenty ninth cockfucking thrust to the hundred and thirty seventh.

Anna’s thighs were spread at almost 45 degrees to each other to accommodate her grossly swollen nuts and even then her jizz-filled ball flesh spilled over her sweaty thighs.

After fifteen minutes and many more orgasms Anna’s mind was mush, a sea of pleasure with a curiously clear image of the inner landscape of her cock and balls. She couldn’t see, as her eyes were rolled super far back in her skull, and even then crossed with pleasure. Touch was a sense completely overpowered by electric orgasm. Smell was just an ocean of sweat and musk and cum, both fresh and stale. Hearing was her own thundering heartbeat and taste was just her mom’s jizzy funk.

But she knew to a fraction of a heartbeat when her mom’s heavy, pounding rhythm stuttered, just a bit... almost imperceptibly.

*GGOOOOSSHSH GGGOOOOSSSHHSHS GGGOOSSSH*

The first three shots bloated Anna’s already tortured dick bigger, fatter until her mom’s hands caught up with the pleasure fried nervous system of the bigger woman.

They let go.

Anna’s mouth opened and maybe she screamed, but if she did only dogs could hear it. The release was so immense as to be a torture in and of itself, and her whole body was vibrating like the shortest, highest, most piercing note a violin could make.

Cum rushed up her cock...

... and met the deluge being fired down into it by her incredible goddess of a mother.

A bulge like a dog’s knot thumped out to immense size at the base of Anna’s cock as her mom’s increasingly forceful load met Anna’s pent up tidal wave of jizz.

The world swam in front of Anna as she was able to compose her wits enough to see what was going on. And when she did, she came again, inadvertently making the bulging ‘knot’ swell even larger and move a little up her straining overstuffed shaft.

Anna’s cock rose from behind her cum-stuffed, pregnant looking tummy like a demonic tower of sculpted flesh in dusky, and red, and shining purple flesh laced with throbbing veins. Twisted and misshapen, vastly wider than it’s usual pussy-punishing width, it bucked and heaved with shuddering intensity as it was assaulted from within. Behind Anna’s dickhead, against the light, loomed a swinging, lumpen eclipse of tightly stuffed ball flesh, a brutal sexual promise connected to a thick, gnarly trunk of paler, tighter and sweatier cock meat.

Anna’s mom’s dick didn’t make any sense on its own. To understand it, you needed to understand a deep-chested, broad shouldered behemoth of a woman who was effectively seven feet across and five deep from tip of nipple to the backs of her bulging, cowl-like trapezius muscles. And it was solid. The cock-fucking that Anna’s mom was giving her was like a jackhammering of robotic intensity as huge thighs like the tireless, trapped muscle of entire champion male bodybuilders - each - pounded Anna’s mom’s man-shaming piece in and out on a foot and a half throw. And yet the only bit of that muscular mass jiggling at all were the very tips of Anna’s mom’s nipples and the weirdly, absurdly, hard and firm tits they were attached to. Everything else was too striated, lean, ripped and flexed to allow any feeling of fleshiness at all - looking instead like warm living steel in the dark light.

You could only understand Anna’s mom’s dick-fucking girl meat if you knew that each of the hugely thick, chunky, ripped blocks of abdominal muscle weighed 8 to 12 pounds on their own - and that each ripped, twitching ab, each super-built thigh was covered in throbbing, squirming veins that met at Anna’s mom’s crotch and fed mighty volumes of blood and steroids into the proof of her goddess-hood.

Her throbbing, meaty dick - the same huge shaft and flared head that, although shorter and narrower than Anna’s monster, was slowly taking it, taming it.

“YYEEESSSS!!” Anna’s mom hissed through clenched teeth, “GNNNMNNNGHHHH! MMMOOORRREEE!”

Anna felt her body lurch as the flow from her mom’s
cock redoubled, pushing the lump in the base of Anna’s dick lower, trying to hammer it back into Anna’s heavy balls.

“MMMOORRRE! MMMOOOREEE! MOOOORRRE! MOOOORRREE!” Anna’s mom chanted and the gym was full of sharp reports as the joints in Anna’s moms fingers popped under the strain of the shaking-fisted flex the older woman was powering into, pushing all of her freaky biological potential south, turbocharging her sex.

Anna howled again, and again, as the flow intensified and she looked up into the hungry, pitiless eyes of her lust-drunk goddess. There was an audible squelch of flesh being massaged, assaulted, forced aside and one, two, three, four grunts from her mom.

Then Anna saw the motion - it was her mom’s tightly packed nutsack and it was obscene. The flood of new, hyper-virile testes that had combined in that scrotum wasn’t repeated, so much as forced into action again at a different order of magnitude. Testes twice the size of ostrich eggs, far larger than even seemed possible, were being birthed into that stretched out ball bag and crammed in tighter and tighter as new ones followed.

Anna watched, stupefied as her mom’s powerful hands, dwarfed by that squirming mutant ballsack gripped the tortured flesh of that churning scrotum and squeezed, using main force to power more cum her mom’s gushing dick and into Anna’s monster, blasting the bulging knot of cummy war zone back into Anna’s balls and ending the struggle once and for all as Anna’s legs were quickly forced further and further apart as her mom’s seed mixed with her own and changed Anna’s testes forever.

It didn’t stop, for twenty two minutes, Anna’s mom came over and over again into Anna’s balls, the very nature of the sperm growing and changing as her mom’s ridiculous biology pushed past the limits of human again and again.

Long since immobilised by her own balls and pushed past the limits of exhaustion, Anna lay on the floor of the gym as her mom tugged her cock free of Anna’s urethra for the last time and wrung out the last two pints from the slowly softening meat onto Anna’s chest. Sperm the size of mice wriggled across Anna’s chest like alien spores and Anna could only endure/enjoy the sensation, unable to move.

Anna’s mother on the other hand was radiating energy and a mad, almost feral, carnal joy. The towering muscle mountain leaned down and, with strong fingers, she plucked the mega-spermatozoa one by one and mashed them against Anna’s large, straining, bullet-hard nipples. One by one sperm, Anna’s flesh succumbed, as her monstercock had succumbed to her mom’s dick and her balls to her mom’s seed, and she felt the strange super-sized cells squeezing their comparatively huge masses down her milk ducts and into her slowly swelling tits.

“Whore...” her mom purred lovingly, the rich contralto of her voice at odds with the nasty word, “I’m going to make your body into a monument to me. I will fuck you in ways you can’t even guess at... and I’m going to enjoy every second of it.”

Anna looked up at her mom with a mad kind of hope in her eyes, and then simply said, “P-Please! Please fuck Slut, Mommy!”

“Of course darling,” her mom chuckled, turning and stepping over to stand astride Anna’s waist, lifting her majestic cock and balls out of the way of the older woman’s desperately dripping pussy, “it’s time for my third shot after all!”

/////

It was not the same day anymore. It felt like it might not have even been the same month.

Anna’s mom was looking into Anna’s eyes with the level, unflinching gaze of a hunter studying her prey as her mom’s massive hips hammered up and down Anna’s monster, driving it in and out of that huge, muscular pussy at a furious pace. All the while, Anna’s new goddess was jerking her own thick dick with one strong hand, the other arm braced next to her daughter’s body like a towering temple column holding up a sculpture of pure power.

Anna felt safe, secure, under her goddess.

Anna’s belly had shrunk away as her body had digested and absorbed the seed in her stomach and the rush of hormones and energy had given her enough strength to stay awake, alert and to let her eyes and hands wonder, marvelling, over her mom’s huge body. Anna knew that her own body had been changed, remade and improved in some subtle ways - she’d catch the occasional glimpse of her own toned, leanly muscular forearm or brush a bump of abdominal muscle where there had previously only been a hint under her flat tummy.

Anna liked being better, being better for her mom.

And then there had been the not-so-subtle changes... and Anna liked those too!

After hours and hours of being fucked hard by her mom, of watching that tireless, huge body use hers, of trying to cum over and over... her balls were still enormous, shining cum-tanks pinning Anna’s legs that sloshed and gurgled with her mom’s and her own mixed sperm - an unholy concoction that was fizzing away in its own fire alchemy of hormones and protein and mutating, changing biology. Each time Anna came, her mom would grind down hard, mashing her sex down to Anna’s root and flex hard, internal muscles crimping off Anna’s monster again with all the terrible efficiency her mom’s hands had managed earlier.

Anna loved the pain and the pleasure of her monster, loved the pleasure it was giving her goddess.

But there was still plenty of cum to go around, as Anna watched her mom’s jerking arm speed up its actions and aim her mom’s freaky new dick down at Anna. As it had happened many times before Anna felt the first powerful, heavy blast of her mom’s mutant supersperm thunder into her face, neck and chest, the next shot covering Anna’s belly and arms and face again. The deluge kept coming, like squishy, hot hail of enormous sperm cells and Anna gasped for breath and choked down cum as she felt the mutant sperm wriggling all over her body.

She giggled as wrigglers stretched her nostrils out to fuck their way up her sinuses and into her brain, or into her ears, pushing them in with desperate, trembling fingers when they got stuck - they melted inside her like a drug, soothing her, warming her, clearing her thoughts, keeping her lucid and hugely aroused. She scooped a few into her mouth, feeling her lips and teeth and tongue tingle as they popped with salty-tangy musky gushes of flavour.

Anna felt great.

Her hands collected great, milky shining heaps of squirming sperm and corralled them, wriggling, up the slopes of her giant, round boobs and to the puckered, shot-glass-sized pleasure bombs that were her nipples. She trembled as hundreds of these swimmers found the only holes around and dived into her grossly enlarged tits through the shafts of her long nipples, pushed in every now and then by her long-nailed fingers. Anna loved the way she could push her fingers down through the nipple into her spherical, vein-covered tits all the way to the knuckle.

Her belly tingled as several more sperm wriggled their way into her belly button and she felt them enter her, their weird chemistry doing something to her. A couple of the megasperm even came to wriggle against her eyes and she gasped in pain and pleasure as she pushed them roughly into her tear ducts, feeling incredible pressure in her head for a second before they popped too and her eyes were bathed in liquid ecstasy.

When she opened her eyes again, the world was brighter, clearer and sharper.

When she finished her skin was clear, shining and smooth, tauter and more resilient than any human flesh had a right to be.

“Oh Mommy,” Anna breathed, her voice sweet and innocent, “I love you soooo much!”

The eyes she looked up into, set in her mom’s severe, beautiful face, widened at the sheer Lust and joy in Anna’s words. The next downstroke of her mom’s tireless legs was harder, less controlled and Anna felt her monster expertly bent by freakishly capable internal muscles in her mom’s pussy. The floor seemed to shake as Anna’s mom rose up and dropped again, further, faster, nastier as Anna’s monster finally ploughed up into that secret haven, driving deeper and deeper into her mom’s Fallopian tube until the gaping mouth of Anna’s cumslit almost swallowed the mutant organ.

“I - nnnghhhh - love you too... Slut,” Anna’s mom purred as she sat impaled on Anna’s monster, “Now give me my last shot: make me... oh- oh- MORE!”

There was a moment of appreciative mutual silence as muscles relaxed and strange, freaky biology was left to run its course.

Anna’s mom slowly leaned back in that quiet moment and closed her eyes serenely, biting her lip.

*TTTHHHHOOOOOOOOOOMMMMMM!!!*

/////

Kasey Edwards was cursing, looking down at the lawnmower she had been saddled with by her parents when they’d left for church this morning with a cheery, “Mow the lawn, dear; you need to earn your keep if you want another semester of tuition from us!”

It was nearly fixed again after she’d had to get Dad’s tools out and take off the cowling, undoing the intake to clear out a clog of damp grass. The only problem was the last screw had dropped back into the mechanism and was going to fuck the whole machine if it got sucked into the blade housing. It was a big lawnmower and she wasn’t going to be able to lift it up to shake the screw out.

A few hundred feet up the road a dog started barking and a mailbox toppled, then Kasey heard it.

*TTTHHHHOOOOOOOOOOMMMMMM!!!*

It sounded like an explosion, or the noise a plane made in movies when it went supersonic. She barely noticed the screw she had been looking for bouncing off her foot as a rumbling vibration shuddered the irritating metal fixing free.

Then the noise came again.

And again.

And again, followed by a wild roar of rich, sinister laughter.

The noise came again and again and again.

/////

Anna slumped against the chest press machine and panted, shivering as the air returned to her lungs. Idly, she fisted a thick gobbet of squirming megajizz into her nipple, grunting again as she felt her tit expand, veins all over it throbbing as it caught up to her other boob.

Her legs were covered in the wrigglers as she stood there, like an island in a white lake and she could feel hundreds, thousands more of the sperms trying to swim up her gaping, aching cock where it was submerged in the fluid and also grind against the wrinkles of her wonderfully reduced ballsack, futilely trying to get in through her skin.

It had taken a panicky twenty minutes to force her way past massively swollen flesh, iron-heavy muscle and a rising tide of jizz, but Anna was clear now, if still knee deep in what must have been several thousand gallons of cum over the area of the basement gym.

“HHHMMMMMM...”

The moan of pleasure came from somewhere over the other side, where Anna had swum from. Anna suddenly had to struggle for balance as the cummy lake around her swirled and a current tugged at the backs of her newly strong thighs, her legs now sporting the kind of Brazilian curves, muscle and mass that would drive men and women crazy.

In the gloom, she had to squint to see what was happening, even with her sight as clear and sharp as it was now.

There was a horrific, organic squelch like fleshy tissues being smashed, or someone slamming two raw steaks together - only this one noise went on and on, changing, developing, twisting further and further. The level of cum in the gym suddenly dropped six inches.

The noise returned, more disturbing than ever, and Anna could hear a whispery moan over the top of it, muttering words just beyond hearing, feverishly, rhythmically... nearly a chant.

Soon, Anna stood in the gloom, slicked with cum and sweat and on a floor covered in only a thin glaze of faintly wiggling, popping, super sperm. It took several more minutes for the noises to stop and then there was only the sound of a voice, murmuring.

“Where is my lovely Slut?”

Anna slumped to the floor, her monster - tired and abused as it was - suddenly rock hard and jetting thick gouts of her own cum into the room. The voice was intense, intensely commanding, dominating, erotic and it gripped Anna by the balls and squeezed. It was the voice of a goddess and it demanded tribute.

There was a thud and a rumble of vibrating masonry, then another, then another.

Out of the gloom came a figure from legend, with skin perfectly tanned to a white-gold so even that it looked like the flesh of the figure was metal or fine porcelain.

At just under seven feet tall and six feet wide Anna’s mom was imposing, muscular, enormous... and smaller. And didn’t have a cock. But her body was a work of art in every proportion - from the symmetry of her huge shoulders, each the same size as her head, to her stack of abs that sat cradled in a heavy, thick Adonis belt and grew by pairs as her bulging ten-pack swelled at the top, as if to support her boulder-like pecs and huge, buoyant tits. Each tit was incongruously topped by a silly, proportionally tiny implant - the last vestiges of a previous body. Even as Anna’s mom thumped heavily towards her, too heavily, Anna watched as first one fist-sized silicone sphere and then the other were seemingly ejected from her mom’s nipples by main muscular force of flexing pectoral against tight, smooth skin.

It was glorious to see, but every footfall sounded like the world was ringing, the building around them seeming to shake. As Anna’s mom got closer Anna could make out more parts of the vision in front of her, too close to be able to take in the majestic whole of it. Her mom’s eyes had gone from a flinty dark brown so dark it was almost black to a startling amber that seemed to glow in the dim light. The short cropped dark hair of a hardcore gym machine was replaced with a wash of dark curls that fell all the way down to a projecting shelf of gluteus muscle that made ‘bubble butt’ sound like a phrase far too small and fragile to describe it. Everything about Anna’s mom seemed somewhere between succulent and granite hard.

Her mom’s familiar features, already sternly beautiful in a kind of Roman way, had become at once achingly feminine and unashamedly strong - thick jaw muscles accenting a fine chin and sweeping, sculptural cheekbones, all surrounding a mouth that was lush and tempting without being pouting, or bimboish, or suggestive. Anna’s mom’s old features were still there but tweaked, smoothed, enhanced and perfected.

Anna’s mom took one last step and thumped to a stop a couple of feet away from Anna, towering over her and exuding a kind of physical pressure. Even the floor cracked under those perfectly formed, strong bare feet.

“Wha-“ Anna breathed, confused, aroused and vulnerable.

“Ha, I can see it,” said her mother, looking her up and down with those startling eyes , “it’s like I can see every change in you, still churning away in you.”

Her huge arms reached forward and settled gently on the sides of Anna’s head, and Anna nearly flinched as her goddess leaned closer and closer, looking into Anna’s eyes... even seeming to look straight through Anna’s skull at some points.

“Yes! You are soooo close... I will make you perfect... and then I will surpass you again and again and again...”

Anna shivered, but croaked a question: “The... Game?”

“Ah yes... we will still play, and if you are very very clever indeed, you may win again, even win often...”

Anna’s mom leaned in and purred in Anna’s ear, “But I know now how much you love losing, being used... being FUCKED... being made into something more than anything you ever had the courage to confess, even to yourself. I didn’t even need these shots to know that... Slut...”

Anna felt confused, not by her mom’s words, but by a more primal sense. Her mom was smaller and less overtly sexually intimidating in every respect than she had been hours earlier, but Anna’s heart was hammering in near panic at being so close to her goddess. She almost wanted to run.

Her mom just chuckled at the look of longing and confusion and fear on Anna’s face, and the sharp look of dominance, intent and simmering lust returned as Anna’s mom licked her lips.

“Don’t be afraid, Slut,” Anna’s mom purred as she began flexing her muscles individually, with perfect control, “I’m still going to fuck you like nobody else ever can or will...”

In front of Anna’s eyes she saw each flex seemingly blow mass from nowhere into the flexing muscle and leave her mom bigger, thicker, more yoked than ever. It was impressive, almost robotic, as a level of control.

Biceps measurements leaped from perhaps 30 inches around to an impressive 36 inches with just a twitch. Quads already 70 inches around leaped out to 85, and settled into harder, blockier masses. Anna watched her mom get at least an entire foot wider and deeper in front of her very eyes... and several inches taller, as if that was a thing flexing could do. And then Anna’s mom glanced over at one of the mirrors and the height dropped a couple of inches to look thicker, bulkier and more powerful.

Had that... just... happened?

Anna recoiled, startled, her hands jerking away from the veiny, boulder-like muscles that she wanted to grope and touch and feel. Her mom just chuckled.

“If you think that’s intense, Slut,” Anna’s mom purred, voice deeper, more sultry and more resonant, “then you’ll probably not even understand this... MMMNNNNGGGHHH! OH YEEEEESSSSS!!!”

A shadow passed the high windows of the gym and the flickering of the light made it look like stop-motion animation as Anna’s mom finally, powerfully, flexed down hard.

Anna’s first view was her mom, huge and imposing, suddenly covered in veins almost from head to toe, like a statue covered in old, thickly grown vines that seemed to radiate from her sculpted pussy outwards. It was obscene... and so arousing that Anna would never be able to forget it.

The next still image was strange, a sudden change in proportion about s legs and arms and torso and chest stretched, leaving her mom comparatively spindly again, but with the incredible looming height and width that made Anna felt insignificant.

The third and final image out of that flicker of shadows was like a wall of muscle, a block of it. There was nothing proportionate about it or sleek or refined, just heaving, butched-out muscle and huge tits wherever Anna looked. Her mom’s middle had swelled further and further out as even a hugely sized torso couldn’t pack in all of those muscles without transforming into an utterly extravagant, chiselled muscle gut and parody of her mom’s cum-filled belly from earlier.

Anna’s mom looked beautiful, incredible... brutal.

“NNNGHHHH YYEEEAAAHHH! I’M SUCH A FREAK!” Anna’s mom growled, smiling, her lips shining with drool from her exertions.

Anna jumped as her mom reached out and groped Anna’s tits, the swollen firmness of them and the veins that made a mockery of their cartoonish super-feminine shape enough to make Anna’s mom bite her lip and moan. Those huge, strong hands separated and one rose to caress Anna’s neck, feeling the toned thickness of it, feeling Anna’s face lightly and making Anna acutely conscious of the fact she couldn’t see herself, hadn’t seen herself since she had been changed. The other hand stroked down Anna’s cobbled belly and found her huge, half-hard monster, stroking it once or twice before those strong fingers slid lower and beneath Anna’s balls.

Anna hadn’t noticed how sensitive her pussy had grown, the sensations of it changing, or even when it had changed, lost amid the rush of other strange pleasures. But grown it had and in an artful way - more lush, more inviting, more sensitive... and tighter, far tighter than before, tighter than even seemed human. But it gave delightfully for her mom’s strong fingers and Anna rose up on her toes as an explosion of female pleasure rocked her mind and set her screaming, fluids running freely down her strong, toned thighs.

“I’m so much MORE than you now... I’m BIGGER, BETTER... EVERYWHERE!”

Anna’s mom lifted an arm in a bicep flex and the muscle that rose there defied comprehension. From 36 inches around mere moments ago, it had grown with Anna’s mom’s body until it was a solid 50 inches around, nearly out of scale even for that massive physique, but flexed...? It just rose and rose, more and more veins leaping to the surface, thickening and pumping huge volumes of blood into the muscle as it rose higher and higher, swiftly passing the top of Anna’s mom’s head and rising until it towered a foot above the clenched fist of that flexing arm. The peak at the top of the muscle was a savage, jagged crag of pulsing brawn and cut to absolute shreds beneath skin that struggled to contain it.

Anna’s monster slammed up between her mother’s enormous thighs to crash into that muscle-smothered pussy with the force of a car accident. Anna was trembling with primal, hindbrain-induced arousal that hijacked her libido and primed her to breed.

“NNNGHHHH, OH- OH GODDD THAT WAS GOOD!” Anna’s mom threw her head back and shuddered, gushing pussy juices in a jet as she came at the sensation, hosing down Anna’s monster, “BUT I THINK I CAN DO BETTER... BIGGER!”

With a startling speed for someone of that size and bulk Anna’s mom picked her up and lifted, apparently without much effort until Anna’s hips her at her mom’s head height, the massive bulk of the monster forced downwards, dickhead grinding off Anna’s mom’s thick abs and sloping shaft snug between enormous pecs and tits.

With heavy footfalls Anna’s mom thundered across to the mirror and Anna could see herself for the first time, held helplessly up in the air like a baby - a buff Brazilllian-style Barbie doll with a cock that looked like it ate other dicks and a hint of a college girl that Anna nearly recognised as herself. Anna flushed at the thought, seeing it blort a thick gob of jizz over her mom’s incredible middle. Her cock had, indeed, kind of eaten another dick - and now that previously-consumed-cock was... missing.

“NNNHHHHHGGGG! Here it COMES!” Anna’s mom grated out through clenched teeth as her hips jerked forward, seemingly involuntarily.

Looking in the mirror Anna had no idea what was going on until she watched her mom’s thick, button clit expand and bulge outwards from between meaty folds with a troubling sound like a watermelon being dragged out of a tub of animal fat. There was a long, layered squelch as thumb-tip sized clit swelled to golfball sized and developed a winking, distinctly penile slit. In seconds, the head had swollen further as more and more flesh emerged from the meat of Anna’s mom’s sex, like a slow, deliberate birth. With a grunt and a lewd squish of lubricant and mass, Anna’s mom forced out the rim of the glans, the dickhead far bigger now than any baby’s head had ever been and followed only by more, thicker, cockmeat.

The process was slow, arduous and deeply moving for Anna, like watching old NASA launches might have been to some devotee of the space race, some connoisseur of the cult of technology. Anna was a devotee to the cult of cunt, and she was enraptured as that heavy stub of crotch beef emerged, thickening to eight inches wide where it grew from Anna’s mom and even that was only at a revealed length of nine inches from cobbled abs to weeping tip.

More and more cock emerged from her mother with agonising slowness as the veins around her crotch pulsed thicker and more insistently. The fat, glistening shaft grew thicker and thicker, and Anna watched as the fuckflesh grew gnarly and bumpy and covered in more, squirming, throbbing veins as more dickmeat emerged. The first foot of emerging dick twitched in the fetid, musky air of the gym and Anna watched, bemused, as the emerging flesh stretched this strange opening in her mom’s sex wider and wider, the shaft letting out a liquidy fart of trapped air from some inadvertent fleshy seal as it continued to ooze out of her mother’s immense body.

Anna licked her lips as she heard her mother groan and the glistening cock began to angle upwards as it emerged, sliding up between Anna’s thighs and tantalisingly close to stroking the back of her ballsack as it continued. Her mom’s cock was a glorious beast and Anna blinked as she realised that it was already fatter than her monster, if not nearly as long. Anna’s mom shifted a bit, moving the angle of her hips and doing her best to keep Anna lined up above that huge, intimidating weapon - and Anna gasped as suddenly six inches of shaft erupted into view and more quickly followed after it.

The huge, bulbous head mashed up against Anna’s tight pussy and began to lift Ann’s body by main force as the enormous shaft just kept on coming, with increasing speed. Anna realised that her mom had switched from holding Anna’s body up, to actively pushing her down, strong hands moving to grope Anna’s toned, powerful bubble butt and spread those big glutes wide as the pressure increased.

“Oh- oh! OOOOHHHH!” Anna moaned as she felt her labia stretch and stretch to try and admit her mom’s beast, the melon-sized dickhead being driven up into her body with incredible force. She heard her mom hiss through between clenched teeth and felt the pressure on her sex increase dramatically as yet more enormous mommy dick emerged from that incredible body.

“NNNNGGHHH, YESSS! BIGGER! BIGGER!” Anna’s mom moaned and jerked her hips forward, driving her cock into Anna’s super tight pussy with main force and causing Anna’s tight washboard stomach to bulge out lewdly around that increasingly huge beast... and Anna wasn’t even taking the thickest part of it yet.

20 inches of dick had erupted from Anna’s mom’s body, peaking at 15 inches across before the huge shaft began to narrow again - eight inches of that savagely sized beast was up inside Anna now and travelling up her cunt as a very visible bulge. Now that the thickest part of Anna’s mom’s dick was through the rest of the throbbing shaft followed quickly and Anna felt her spine straighten as the huge invader mashed into her cervix... and simply smashed through it in an maelstrom of pain and pleasure that filled the gym with her screams and spattered the floor with her pussy juices.

“MORE!” the two women groaned at the same time and Anna’s mom was only too ready to oblige as she watched the bulge of her dick slide out and over her daughter’s rib cage, a freakishly stretchy tube of smooth, unblemished flesh wrapped around Anna’s mom’s behemoth and mashed up between Anna’s oversized round tits.

Anna shuddered, and her eyes rolled up as she jerked on the cock impaling her, stretching her ridiculously elastic womb - this orgasm had nothing to do with Anna’s monster, though it did throb harder, liberally dousing her mom’s body in precum. The position Anna was in, and the strong, unyielding downwards pressure on her hips from her mom’s hands, had pushed Anna’s trapped monster further and further down - it let the massive shaft grind down her mom’s perfect, divine body and slip between her mom’s astoundingly muscular thighs to mash against Anna’s mom’s muscular, powerful pussy. Anna’s heavy balls soon completed their descent too, settling to drape heavily over her mom’s massive beast as it fucked it’s way deeper and deeper into Anna’s body.

Anna looked down and saw the huge bulge of her mother’s megameat, wearing Anna’s belly flesh like a living condom, press up through the valley between Anna’s overinflated tits. Without thinking, Anna dipped her chin and began tonguing and kissing the obvious bulge of the cockhead, making out with the cock that was fucking her cunt, womb and tits simultaneously.

Anna moaned into her flesh and heard her mom moan in sympathy as the vibrations travelled down her cock. A tilt of her chin and Anna was able to catch a glimpse of herself and her mom, locked together in a vision of superhuman sex. The last thing Anna was aware of was the wandering vagueness in her reflection’s eyes and the feeling of something brushing her trapped monster as orgasm briefly wiped her mind clean of anything but pleasure.

In the supernova silence of her own howling climax, Anna felt two words echo through her soul and shuddered as the pleasure redoubled.

“BIGGER! BETTER!”

/////

Kasey crouched, shuddering, in the bushes by the corner of the basement window, squinting hard to see inside, even in the little pocket of shadow she had found. Her shorts were soaking wet and her mouth was open in an ‘O’ as she came all over her fingers and carried on staring at the scene below.

/////

Anna’s cum had painted the floor in a huge swathe behind her mom, the bucking, heaving mass of Anna’s monster now softening and returning to half hard.

Anna panted and tried to move, but she was still draped like a human cocksock over the huge member stretching her out. Even as her head lolled and she looked over to the mirror, to see herself, she noticed her legs were still twitching with the aftershocks and her huge tits were bouncing slightly as she sucked in breath after tortured breath. Her throat felt raw and she guessed she must have been screaming. She saw what had brushed her cock earlier, as she descended into oblivion: it was a pair of swollen orbs that descended, one to each of her mom’s labia, causing those lips to bulge and droop around testes each the size of basketballs, if not bigger.

Then her goddess shifted her grip and lifted Anna again, mauling Anna’s big bubble butt as she did so. It felt like being turned inside out, but in the most amazing way, and Anna bit her lip, feeling her pleasure build again with amazing speed and ferocity as her mom’s beast ruined her pussy for anything less than this kind of complete sexual domination. It felt like completion... but also the twisted, needy side of Anna wanted-

“M- More!” Anna croaked, reaching up to finger her nipples, two digits sliding into each overstretched nub.

There was a dry cough of a chuckle from Anna’s mom and then finally, “I - NNNNGGHHH - thought you’d never ASK! HNNNNNNGHHHH, OH, OOOHHYYYEEESSSSSS!”

Anna felt her mom’s hands leave her, only the massive trunk stretching out Anna’s cunt and womb holding her up, and even then in a nearly vertical position. Her mom’s hands found and parted those two new massive balls in their churning labia-sacks, gently moving Anna’s drooping monster out of the way. Anna tilted her head back and the world turned crazily upside down as her mom’s inverted reflection cocked her hips further forward and crunched, showing her vulva to the mirror, to Anna, and spreading the rest of her feminine folds to reveal a wet, gaping, gushing pussy and a winking little piss hole.

“HHHHHRRRRRMNNNNNNGGGGGH!” Anna’s Mom grated out through clenched teeth.

In a rush, Anna saw the tiny urethra bulge massively and a huge mass of meat thunder out into the gym in a terrifying, potent display of power... as a new cock, every bit as terrifying as the beast currently throbbing against the back of Anna’s hugely stretched womb, emerged in a rush. The last few inches of the three foot length seemed to bend enough that the huge member could rise upward and slap heavily into Anna’s back, delivering a meaty whack that shook Anna and made her gasp in surprise and mind-broken desire.

Anna felt her mom’s huge arms tense and grow thick with flexing brawn as she was lifted bodily up the shaft of the cock brutalising her cunt, raised high enough that she was able to perch on the slightly lower glans of the second, new cock. Anna was limp, exhausted and on the edge of another mind blowing climax, but she managed to reach back and use her long-nailed fingers to pry apart her asscheeks and kiss her mom’s second cockslit with her winking asshole.

“Ah! AHHH!!! AAAARRRRGGHHHHHYESYESYESYESYES!”

Anna’s ass had sneakily become a work of sublime erotic art, combing a near-perfectly arousing combination of padding and power that invited plenty of squeeze, but as her mother was finding out, offered very little give. And Anna was finding out too as she felt her glutes spread wider and wider apart, the miraculous stretching and pliability of the rest of her body somehow not extending to this puckered rear entrance. But her goddess would not be denied and the initial pain gave way to an incredible sensation of pleasure and fullness as a second cock, bigger than Anna’s own monster as well, found a way in deeper and deeper.

It was the apex of the idea of double penetration and it was... glorious. She was being pulled down the twin cocks inside her by her mom’s amazing strength, the thick sides of beef her goddess called arms bulging to brutal unreal size as Anna was forced lower and lower.

But Anna wasn’t idle, grinding her hips and contorting her whole body to fuck back as hard as she could into the dicks deforming her entire torso, reaching up to frantically finger fuck her freaky nipples as she was pushed down into the brutal double stuffing. She barely took a second to haul her quickly stiffening monster up out of the way and park it vertically between her mom’s titanic, bloated pecs.

Where Anna’s belly and was being stretched up between her tits, snugly wrapping her mom’s immense dick, the fleshy cock-club in her ass was straightening Anna’s spine as it ploughed up through her body, the head so big and fat it made Anna’s sternum ache and forced her racing heart against the huge fuckmeat. Just the feeling of so much of her mother in her, stretching her, was enough to cause Anna to paw at her naked body and try to fuck her nearly-hard shaft up between her mom’s chest beef. Anna even heard her toes click before a wave of grunting, trembling, lip curling pussy and ass orgasms shook through her and made her nearly black out.

“Hhheeehhuuuhhhh,” Anna rasped, realising that her breath was being hindered a bit by the shafts dominating her body.

“M-more!” the word came out as a tiny suggestion of a wheeze, but Anna’s mom heard it and Anna, through tunnelled vision, saw her goddess smile wickedly, amused.

Strong hands closed around Anna’s arms and she found herself pulled into an embrace, mashing her overstuffed, vein-covered boobs against her mom’s huge pec-backed bust. Anna groaned as she felt their nipples fencing, her mom deliberately teasing Anna by flicking thick, long nubs over Anna’s own hungry tips and pulling away before Anna could push forward and grind her nipples into the stimulation. Anna whined in frustration at the fleeting contacts that promised so much stimulation, but delivered so little.

Then Anna’s mom stopped holding Anna up with her strong hands, and instead brought them to cup her own heavy tits, leaving Anna in place and supported easily by the two cocks inside her. With a flex of bulging muscular arms, Anna’s mom gripped her nipples and tugged upwards, the tit-flesh giving enough to allow her boobs to sit almost atop Anna’s, the twin teats pointing up over the huge swell of Anna’s orbs.

“OOOHH... OOHHH YESSS, I CAN FEEL THEM...” her mom groaned as those powerful hands found the older woman’s areoles and began cupping and squeezing them roughly, rhythmically.

Then Anna grunted and felt a new rush of fluids gush from her overstretched cunt as in each of her goddess’s tits a huge bulge began to push up under the straining nipples, forcing the caramel nubs flatter and wider. Anna licked her lips as she saw the chunky teats stretch open like mouths in song, and looked down the opening of each to find a pinky-purple slit winking back at her and drooling a familiar slightly cloudy lubrication. Anna’s mom’s nipples stretched wider and wider and wider until they were a pair of finger-thick rings over a handsbreadth across in a crinkly sea of puffy areole - and then two huge cockheads slid out and through the gaping nipples with a sound like flesh being greased.

More and more shaft quickly followed until each cock was over a foot long and thicker even than Anna’s newly bigger, toned arms.

“More...” Anna’s mom breathed as her main two cocks moved inside Anna and let the younger girl tip slowly backwards, massive tits thrust up and out by the cock ravaging Anna’s ass and straightening her spine. It was enough to allow Anna’s mom’s tits to slowly slide down Anna’s sensitive tit flesh until the meat of two hot, lubricated breast-dicks came to rest heavily on Anna’s ludicrous chest, mashed against Anna’s lusty, hungry nipples.

There was a small sound, a squeak, and Anna saw her mom quickly flick her eyes to the source of the noise. Anna’s mom’s lips quirked up in the barest hint of a smile and then those amber eyes were back on Anna and feverishly intense.

With a grunt, Anna’s mom gripped one of her breast-dicks and bent the porn-star-shaming meat downwards until the head was mashed against Anna’s nipple, pressing into the accommodating nub forcefully, the fat tip stretching out the nub slowly as it tried to find it’s way deeper. The second breast-dick was a little more difficult to push into place now that the first was lined up, but Anna watched her mom’s arm bulge larger and larger and larger as more power was poured in, with eventually the irresistible strength of the goddess overpowering the lusty, indefatigable virility of the goddess.

Anna barely cared as she felt her nipples stretch wider and wider and wider, the pleasure she had received from her nipple-probing fingers completely eclipsed by the intensity of pure ecstasy she was feeling.

“AAAARRRRRNNNGGHHHHHFUCKMEFUCKMEFUCKMMEEEEEEEE!” Anna screamed as she desperately thrashed in her mom’s embrace, trying to fuck back and take all these cocks in all her holes at once, jerking madly and baring her teeth in a furious, lusty snarl.

She stiffened as with a pair of SCHLUKK noises the rims of the two cockheads pressing into her boobs suddenly popped in and began ploughing deeper into her strangely changed tits. A huge gout of precum smashed up through Anna’s trapped monster, a gush of cloudy liquid that coated her mom’s chin and bull neck, running down to glaze pecs the size of microwaves and run over the tops of her mom’s mutant jugs - all at the same time as a detonation from Anna’s gushing, ruined cunt hosed down her mom’s crotch for ten long seconds.

“YYYYEEEEESSSSSSS! YYYEESSSSS! PPPLLLLLEEEEEEAAAAAAAASE!”

Anna’s mom curled her lip in a lustful sneer as she pulled Anna close enough to fully hilt her breast-dicks in Anna’s huge, veiny tits, before pushing her smaller, lighter daughter down until each one of Anna’s mom’s four dicks was unable to go any deeper into Anna’s body.

Then Anna felt herself lifted up and away, further and further, all the members stretching her body slowly sliding out in a tide of juices and lube and sex-sweat. Her mom’s arms seemed to swell bigger and bigger as with exquisite control Anna was rotated slightly in the air to stop the cocks in her tits from popping out...

... and the Anna was pulled close, hard and fast, pounded brutally in four holes at the same time as she screamed and flailed and tried to rub every sensitive part of herself all at once.

The second lift and drop was better, smoother and ended with a clap of freakishly overdeveloped goddess muscle on Anna’s thighs as her mom put a tiny fraction of her strength into completing each mind-altering deep penetration with a thrust of powerful hips. Anna came so hard she passed out, gushing, twitching and screaming, howling her pleasure in unashamed passion.

Seconds later a swelling surge of electric pleasure dredged Anna’s battered mind out of the respite of unconsciousness and she surfaced long enough to cum again, harder than ever, her monster bloating enormously as a thundering tide of cum blasted through it... only to stop dead as her goddess’ mighty pectorals flexed in and squeezed hard, stopping the torrent in its tracks. Pain, familiar and unexpectedly missed, poured into Anna and injected raw fury into her climax - sexual nitro for her fucked out body.

Climax built on climax and the world shrank to a roaring, red-tinged sense memory of every nerve in Anna’s body singing in sexual nirvana. Anna screamed and thrashed and fucked like a banshee or a demon: hitting, clawing and biting herself, her mom, even the thick musky air around her as she went mad with sensory overload.

She was drowning in the fucking her mom was dishing out, being overcome by it. Lucid moments flickered past: Anna’s arm disappearing up to the elbow in her own straining monster dick as she fisted it; her mom’s hugely long tongue filling Anna’s mouth and throat as it penetrated far enough to lick the shaft coming the other way through Anna’s empty guts; the sound of stretching flesh as another huge pair of basketball-sized testes descended into Anna’s mom’s already bulging labia.

When Anna surfaced after an hour or two of changing, syncopating rhythms, of hard, animal fucking that used and abused every inch of her supple body, Anna’s mom was going at it like the reciprocating pistons on an old steam train at full speed. Iron hard muscle was powering cock in and out of Anna in a rolling, thrusting rhythm - surrounding her, supporting her and spearing her over and over and over again, even her goddess’ insane stamina cracking enough to demand a ragged grunt at the end of each thrust. Their crotches were like some kind of lewd Newton’s cradle of bulging, swinging, slapping testes, 6 in all, mashing into each other with every pump of her mom’s giant hips.

The perpetual motion seemed to set something off in Anna’s mom, a kinky, insane kind of joy that fed on Lust and sensation and hot, passionate fucking. Anna gagged as she felt her mom’s enormous tongue leave her stretched out throat, leave her mouth and lick across Anna’s lips before returning to her mom’s mouth and sliding out of sight briefly...

... until her mom pulled Anna’s fingers from the gaping slit of Anna’s monster cock and opened wide - to stretch the face of a goddess around a cock that, all shiny red and purple, looked positively demonic.

“MMMMMMNNNHHHH!” Her mom groaned, as if this time the taste of cock was a thousand times better than it had ever been before, and as the same tongue that had dominated Anna’s throat speared the floppy cockslit of Anna’s dick and squirmed deeper and deeper into the shaft of Anna’s monster. Judging from the flutter of Anna’s mom’s eyelids and the continued moans, maybe it did taste a thousand times better than ever before.

Anna’s eyes opened wide then as she felt something she had never even heard of before. Her mom’s muscular control was so complete, so exquisite that the bigger woman was flexing her pecs, making them ripple and dance in unison in a regular, pulsing motion. The effect it had on the breast-cocks fucking Anna’s tits was noticeable, giving each thrust a kind of stirring, churning motion as well, but Anna’s tits weren’t the main event.

Each flex of her mom’s pecs was like having a hard, demanding fist milking Anna’s monster, as if trying to suck up cum from Anna’s balls by main force, one pump at a time. Anna babbled wildly as the rhythm sped up and dozens of orgasms held back, denied and derailed by those amazing chest muscles rolled up Anna’s shaft like a series of thunderclaps.

Anna’s mom barely twitched as the first barrage of Anna’s jizz hit her in the mouth and throat with enough force to pop a normal woman’s head clean off, huge neck and chest muscles worked to drink down Anna’s cum just as quickly as it could be spurted, blasted, gushed or thumped home. Anna could feel her goddess’ muscle gut expanding quickly, pressing into her own dick-stuffed torso... and watched in awe as her mom’s tits ballooned outwards too, driving Anna’s own huge boobs back and downwards as her mom’s raced to catch up in size.

There was a lurch and a loud, cock-muffled moan from her mother as the floor of the gym cracked and that little extra sensation, the frisson of fear and power, seemed to be enough to push Anna and her mom over the edge and into the maelstrom.

Anna threw back her head to scream her climax to the heavens over and over again as she felt two blooms of thundering, hot, wriggling warmth expanding within her tits as her goddess’ breast-dicks lurched and throbbed and blasted Anna’s boobs with cum. More and more and more cum raced into Anna’s boobs, massively inflating them and forcing Anna’s body to slowly tilt away from her mom’s. Anna’s monster bucked and jerked at the sensations, heaving another gallon or two of jizz up into her mom’s mouth with a lurch... and Anna’s eyes rolled up in her head as she felt a matching increase in pressure a moment later in the two dicks pumping up her tits.

Before Anna could choke out another, triumphant scream, she felt a detonation in her fucked-out womb and was lost in sensation as she went from stretched out to looking hugely pregnant in one, continuous blast of jizz from her mom. She tried to look down, but the cock in her ass kept her back straight and the head of that beast pressed into the bottom of Anna’s neck, forcing her to keep her chin up.

Anna opened her mouth, to moan, to shout, to haul in a deep breath... and all that came out was a huge jet of jizz that painted the ceiling, Anna and the gym around them as she looked about and thrashed wildly, shocked by the power of the cumshot from the behemoth in her ass. Anna’s own monster lurched in sympathy, pumping huge amounts of pent-up seed into her mom’s body... and Anna felt, moments later, all four cocks in her throb a little harder, cum a little more powerfully.

Something about that tickled her broken mind.

More and more of her mom’s supersperm bloated and filled Anna’s body, jetted out of her mouth and nose and generally filled every tiny portion of every possible hole it could in Anna’s body. It was more than any normal person could take and even Anna’s changed physique has some limitations.

Quart after quart of thick, inhumanly huge megasperm powered into Anna’s body from seemingly all directions and as her tits surpassed the size of exercise balls, her weight - and the weight of fluid inside her - slowly tipped her further over, her mom’s breast-dicks slowly starting to pull out as Anna’s rapidly inflating belly pushed against her mom’s thick, bulging muscle gut and away from the body of her goddess. Anna shuddered as she felt the member filling her throat and mouth with jizz from inside slowly retreat until the head popped into her stomach and the sphincter at the bottom of her throat snapped closed, trapping the tide of cum and causing her middle to swell outwards faster and faster.

Even as Anna was filled with her mom’s freaky cum, feeling it wriggling and writhing inside her body, she was still helplessly cumming, her monster pushing load after heavy load into her mom’s mouth and veiny, flushed neck, forcing her goddess to swallow a seemingly endless ocean of cum. It was nearly perpetual orgasm, filling and being filled, and it felt like it went on for hours, or even days.

A tiny sound made Anna’s head twitch as it bounced rhythmically to her mom’s unceasing sexual pounding. The noise was barely there, a quiet afterthought to Anna’s hammering pulse, but it drew her attention and she drunkenly looked around for the source.

Then she spotted it.

A girl, around her age maybe, with her thighs spread wide, crouched behind the bushes in the flower bed, with her legs wide open and her fingers crammed into her pussy, tiny shorts hung around one of the girl’s ankles, forgotten. Anna heard the sound again and realised that it was the girl’s squirt blasting against the basement window, seeing the straining, flushed, O-face looking down at the scene of carnal madness within.

Anna glanced back at her goddess and saw those amber eyes had followed Anna’s own and were studying the girl with wicked amusement... and a raw sexual fire.

/////

Anna slowly opened her eyes and rolled over, or at least tried to. Her belly was back to being flat, if even - to her touch at least - a little thicker, harder and more developed. It was her tits that were the issue. Each boob was huge, practically spherical and the size of a beach ball, with her weird, huge fuckable nipples almost out of reach of her own questing fingers. She settled for turning her head, ears slowly informing her of a hard, rhythmic thumping nearby.

Her mom was lying on her front, huge and pale, propped up on her insanely massive forearms, shining with sweat and her hips driving down and forward with great bulging muscular power.

Anna’s mom appeared to have grown another head - a blonde one this time - and a pair of atrophied arms and legs. Anna blinked.

It was the girl from before - long, beautiful, slender limbs looking weirdly spindly and out of proportion against her mom’s sense-defying size and muscles. That pretty young face was screwed up tight, teeth bared and face flushing a deep, sweaty red as she moved and screamed and begged for more, harder, nastier fucking. Anna could see the girls fingers clawing at her mom’s back, feet flexed weirdly as toe joints popped and clicked through desperate spasms of ecstasy.

Anna’s mom saw Anna looking and grinned, picking up the pace.

“Mmmmnnggghh, you were out for a long time, but I - OOHH YES, just like that - thought you wouldn’t mind if I kept myself busy. And - NNNGHHH, Nnnghhh - you just need to see this...”

With that Anna’s mom did a slow, powerful press-up that had the girl drumming her heels into the huge thighs of Anna’s goddess and shuddering, wide-eyed and grinding out swear words through clenched teeth. Anna barely noticed the expression, the swearing... she could see her mom’s cock.

Not just the root of it sawing in and out of the girl’s puffy, rosy-lipped pussy, or the thick mass of it... the girl was so lean and beautifully willowy that Anna could see every single blood vessel, every throbbing vein, every lump and bump of her mom’s dick through the pale, glistening flesh of this girl. Freakily, the girl, already pale was the same colour as her mom’s skin and it looked less like one was fucking the other and more like mom’s cock was melding with this girl’s body.

Anna watched her mom’s thighs and abs tense as the goddess drew her hips back nearly two feet, leaving the tip inside the girl’s body like a bulging, melon-sized cunt plug - and then those massive, blocky glutes crunched down into twin boulders of feminine brawn as Anna’s mom powered her cock all the way home and sheathed her cock in the screaming, begging, babbling girl.

“FUCK MY WOMB! BBBAAAABBBIIEEESSS!! FILL ME WITH BBAABBBIIIIIIIEEEEEESSSS!”

“Well, Slut,” her mom growled as she really began speeding up, giving into the desire for a hard, fast fuck, “I can’t say no to my sexy new - NNNGHHHHH - girlfriend!”

Anna just watched mesmerised as her mom brutally fucked this girl and knew, even as she watched the furious, powerful pounding, that this girl was going to be the first of a long, long, line of begging, knocked-up, desperate cockwives.

She smiled.

/////

“Hi Aunt Wendy,” Anna said around a mouthful of crunching celery as she walked into the lounge with a jar of peanut butter and a bowl filled with more celery stalks. Bending down, she paused long enough to let Kasey take a couple of stalks and load them up with more of the PB. It took a couple of attempts on account of the rhythmic movement, but Kasey just needed the food - she was a growing girl.

Anna scooched around until she could get around to the other side of the sofa and crash gratefully into the soft cushions. She snuggled up to her mom’s huge arm and leaned in, offering up the bowl and the jar. Her mom leaned over and playfully gnashed her teeth, looking pleadingly at Anna and waggling her eyebrows.

With a faux-dramatic sigh, Anna pushed the jar in between her huge boobs, the family-sized jar seeming ridiculously small against them. With a bit of delicacy, Anna dipped a celery stalk in the jar, making sure that it got all the way to the bottom, loaded with peanut butter and slowly, teasingly, fed it to her mom.

She turned the TV on and listened to her mom happily crunching the celery. The first channel was just hardcore porn, with two black ladies with huge black strap-ons double teaming a pair of blondes who seemed to be genuinely having a bit of fun and cutting loose, taking turns. Anna cocked her head and watched for a couple of seconds, before changing over to local news.

“Well,” said a pretty reporter, stood in the familiar surrounds of the affluent little cul-de-sac Anna and her mom lived in, “we are live in the quiet suburban street where the recent reports of earthquakes and disappearances have the authorities shocked.”

At the word ‘disappearances’ Kasey huffed and held out her phone as she bounced so Anna and her mom could see it. There was a message saying, ‘Over at Anna’s, back in a week xoxo’ on the screen, dated earlier that morning.

“Well... good,” Anna’s mom mumbled around her celery, her eyes going back to the TV and the very pretty reporter.

“We’ll be running a series of interviews with residents this week to try and understand the concerns in the community - to try and get to the root of this mystery.”

There were a couple of chuckles on the sofa at the reporters choice of words, but they were overshadowed by a loud, shuddering moan.

Anna’s mom was sat on the sofa, her immense size completely naked and gleaming in the afternoon sunlight. Between Anna’s mom’s thick, muscular thighs, Kasey was hunched over, her huge baby-bump rubbing along the top of her own contrastingly willowy legs as she squatted over Anna’s mom’s lower cock and bounced up and down steadily. Lying on Kasey’s narrow back, Aunt Wendy - normally a picture of tanned, fit soccer mom sexiness - was shuddering through a drooling orgasm as Anna’s mom’s upper beast ruined her pussy, rocking back and forth with Anna’s mom’s gentle thrusts.

“Mmmm, looks like she’s pretty far gone, mom,” Anna opined, looking at Aunt Wendy and idly crunching a celery stalk.

“Mmmnnhhh, yeah, but she still hasn’t told me what she wants... she’s always been a bit shy about her own sexual needs.”

Anna looked at her mom, scandalised.

“Look hun, your uncle’s a nice man and very decent to her, but he’s never going to satisfy her the way she wants, because she’s never told him. She doesn’t even know he’s a voyeuristic, panty-sniffing pervert.”

“Mom!”

“It’s not a bad thing honey, he’s not creepy about it, and I’ve heard he pays the right people when he needs uh, professional help. He just has these things that turn him on. Kinda like the Game for you and me.”

“Huh,” Anna said, nonplussed.

Aunt Wendy began really riding Anna’s mom’s dick and Anna could see the corners of her aunt’s full lips turn up as sexual desperation tipped over into sexual satisfaction.

“YEESSSS! YEEESSS! I WANT BBBBAAABBBIIIEEESSS! KNOCK ME UUUUPP!”

Anna and her mom shared a little smile and Kasey paused in her fucking to do a cute little fist pump, shouting, “Team Babies, for the win!”

They chuckled and Anna’s mom continued to fuck the two women on the sofa as Anna had her morning snack.

Silence returned.

“So, uh... mom,” Anna began, apparently nonchalant, “when do you, um, think the Game is going to be back on?”

Anna’s mom groaned and Aunt Wendy lurched up off Kasey’s back at the cock inside her throbbed massively at the sheer thought...

Anna smiled: it looked like she was going to be Slut again very soon indeed.

She was looking forward to it.
