Chapter Text
Brian had never considered installing a seatbelt extender in his car before, though tonight he sorely wished he had. It was a bit of a squeeze to get his seatbelt secured over the bulge of his tummy on a regular day, but he managed just fine— after having the biggest meal of his life, however, it was pointless to even try. He had put up with restaurant staff making a fuss over his record-breaking belly and taking his picture for the Wall of Fame, then needing a bit of help to wriggle out of the booth, and now this, being jostled as Max struggled in vain to buckle him up on the passenger side. Thankfully he was a very patient and good-natured man...not to mention, aroused beyond belief.
“Well, there’s no way this is happening,” Max said with a sigh, letting the seatbelt snap back to rest and turning the car on in defeat. “At least it’s a short drive. Hang in there, big boy.”
“This is so unsafe,” Brian declared through a spell of hiccups.
“Yeah yeah, I know,” the slimmer man admitted, rolling his eyes and giving his partner’s belly an appreciative pat. “But we gotta get you home somehow. I’d say it’s not my fault you made a pig of yourself and can’t fit anymore, but I mean…it kind of is.”
“Oh, it absolutely is,” Brian confirmed with a grin, hands supporting his swollen middle on either side. “Guess I like it, though.”
“No kidding. You’re gonna like it even better when we get home, I bet,” Max said with a playful grin.
It was torture to keep his eyes and hands off of his partner during the trip home, having to pay attention behind the wheel and be extra safe for Brian’s sake, but the drive really was short, barely five minutes from parking lot to driveway. Max sprang out of the car to open the front door and bring in their winnings (dessert to go and two t-shirts, neither of which were large enough for the actual winner) before coming back to help his overfed partner. Thankfully Brian was naturally quite strong and needed little more than a bit of help to heave himself out of the car, which gave Max the perfect opportunity to drool over the big man and how much of a struggle a simple thing like walking had become, thanks to a night of feeding efforts.
It was slow going, giving a puff or groan for every step with his bloated belly moving as one solid mass, gravity pulling him forward— finally reaching the entryway, Brian quickly shut the door behind himself and leaned back against it for a much-needed break, startling as it creaked loudly from supporting his weight. Cracking open an eye, he took one look at the stairs leading up to the bedroom and moaned in distress.
“What's up?” Max asked, then followed Brian’s gaze upward. “Oh, yeah. The stairs. Hmm.”
“Can’t do it,” Brian said, clearly pained. “Not gonna happen.”
Max chuckled, knowing he very well couldn’t carry the larger man, who was at least twice his size in every way. Proper motivation was key in these sorts of situations, he found, and so he stalked over to give Brian’s belly a brief rub and to palm his arousal through his pants, watching his partner’s expression soften from agonized to contented in a heartbeat.
“C’mon,” Max said while tugging on Brian’s straining waistband.
“Hnnnnope. Keep rubbing, though…”
“Greedy,” Max tutted, giving the big man’s gut a slap to the side.
The sharp sting felt nice, taking his mind off the dull ache of being stuffed to capacity, but Brian still gave a yelp in response. He seemed apologetic after the reprimand, but he had to learn Max had a limited tolerance for disobedience during playtime, and so the smaller man trotted up the stairs with ease to lean against the top banister, calling down.
“You better come up with me, or you’re on your own,” he warned, playfully swinging the plastic bag in his hand.
Seeing that he had Brian’s full attention now, he went about rustling around loudly within in the bag and took out one styrofoam container-- he grabbed the piece of cheesecake from it, holding the dessert up for Brian to see before taking a small but greatly exaggerated bite, complete with obscene moans of pleasure. The larger man inched forward to stand at the bottom of the staircase, looking very conflicted, but stuck to his guns and refused to move any further.
“Still a no, huh? Guess I need to up the ante.”
Smiling devilishly, Max replaced the cheesecake in the container and left it on the floor for the moment, licking the crumbs from his lips while retreating into the bedroom. Drawers opening and clothes rustling could be heard, but Brian stayed put throughout, straining to hear exactly what was going on without putting in the effort of stair-climbing.
“...Sweetie?” he called out anxiously, brows furrowing.
There came no reply, but within two minutes Max had returned, minus his pants. Having changed into a tight pair of black briefs that were altered to serve as packing shorts, he parked himself on the top step with his legs spreading wide to show off the goods: a surprisingly life-like strap-on that jutted from his pelvis and bobbed eagerly with every movement. His back arched just slightly and a sultry moan escaped him while playing with his new cock, closing his eyes but leaving them open enough to see his partner’s reaction through thick eyelashes.
That was it, Brian decided, he had to get up there somehow. Maybe this counted as a moral defeat, but only one part of him was in control now, and it seemed to get a bigger kick out of his obedience anyway.
Usually just an annoyance, climbing the stairs seemed an insurmountable task on such a full stomach, but he pressed valiantly forward, slowly hauling his bulk upward. Once hitting the halfway point at the landing, however, he needed to take a short break and lean against the wall, voicing his distaste for the task with a pitiful whine. Max laughed but it was sympathetic, not cruel.
“Aww, you’re almost there! C’mon, I know you want your dessert, baby,” he cooed, swiping two fingers through the cheesecake and spreading the creamy confection over the head of his cock as encouragement. “Maybe it’d be easier on all fours...?”
Something about that suggestion sent a shiver of arousal up Brian’s spine. Maybe it was in having to admit defeat, that he had eaten more than his body could handle and now his best option was to crawl, like an animal, with his overfilled gut hanging shamefully below him. He reddened while rubbing the curve of his swollen belly, but with his eyes on the prize, the big man lowered himself to continue his climb, thick arms easily able to support his weight.
“Too full to stand but still wants to eat...such a good piggy,” Max teased, slipping a hand beneath his briefs and stroking himself to that thought.
“Oh, god,” Brian breathed heavily, cock twitching below his sagging middle.
Feeling the burn of shame in his cheeks, he bit his lip, loving every second of it. To be fair it was easier on all fours, and in no time he had made it to the last step, settling on his knees and grabbing Max by the thighs as soon as he was able. His heavy belly pressed tightly against the stairs, but instead of being painful it was actually more of a relief, providing some much-needed support for his great weight. Without even having to be told, he leaned forward and lapped hungrily at the generous smear of cheesecake, tongue wrapping around his partner’s erection while enjoying the rich taste, looking up the entire time to gauge the slimmer man’s reaction.
“Ah, you’ve earned your reward, weary traveler,” Max proclaimed, fingers rifling through Brian’s fluffy ginger hair. “And you look so good claiming it, too, I gotta say...”
The corner of his lips curling just slightly, Brian felt a surge of confidence and began to suck in earnest, head bobbing while slowly taking the length as far as he was able, secretly glad the rubbery taste of silicone was masked by the cheesecake. Little moans and suckling noises escaped him while working hard, each one sending a pleasing jolt through Max as if the toy was truly an extension of his own body, complete with highly sensitive nerve endings. Before long it had been well cleaned, and Brian eased off a bit, just lapping at the very end with the tip of his tongue, gaze roaming upward to question his partner.
“Still hungry?” Max asked, laughing as he received a vigorous nod in response. “I knew I liked you for a reason.”
Wearing a wide grin, Max grabbed the remains of the sugary dessert and shoved them into Brian’s face, gleefully watching him accept it all in one big bite-- it was pointless to resist, really. Besides, as full as he was, the bigger man found himself actually wanting the cheesecake after having gotten a mere taste, and he dutifully enjoyed the cloying sweetness and creamy texture in its full glory. Max leaned forward for a moment to plant a kiss upon the larger man’s crown, gently scratching beneath his rounded chin while he chewed and swallowed and smacked his lips in appreciation.
“Maybe we should move this to the bedroom and get comfy, huh?”
“Thought you’d never ask,” Brian replied with a huff, brushing crumbs from his beard.
Max freed himself and hopped up quickly, ready to assist his partner, who was already giving a pained groan with the effort of heaving himself forward. Bracing himself with an arm around the banister, Max offered his help, which Brian took gratefully once he was back on two legs, though was briefly afraid he might rip the smaller man’s arm clear out of its socket while wobbling unsteadily for one precarious moment. Regaining his balance and letting out a tired sigh, Brian let go to lumber into the bedroom and flop heavily onto the unmade bed, leaving Max to grab the second styrofoam container of dessert and appreciate the view of his burly boyfriend from behind.
Finally hitting the mattress and being able to rest was a huge relief after all he had been through. Brian did his best to wriggle out of his clothing while laying down, the bed creaking and protesting throughout the struggle, until he was able to settle on his side right in the middle, blissfully naked. He couldn’t see over the great curve of his belly but he could feel the indent his waistband had left in his pale skin, and his fingers gently rubbed over the angry red marks to ease the pain, thrilled he had caused them himself through sheer, unrestrained gluttony. Max had followed close behind and discarded his shirt in one swift movement, shielding the scars that ran beneath his chest from view, though soon abandoned self-consciousness to simply stare at the big man on the bed, eyes wide with obvious lust.
“Why don’t you take a picture, it’ll last longer,” Brian teased, rolling into a playful pose.
Max cocked a brow. “I could definitely go get my camera--”
“Ah, no, nono, nevermind,” Brian interrupted, embarrassed. “Just joking!”
Shaking his head, Max bit his lip and crawled onto the bed, gravity drawing him right up to fit snugly against Brian’s side-- he felt so small in comparison, and found great comfort in the bastion of soft, warm bulk that greeted him.
“Hey, I wasn’t,” he said, patting his partner’s broad chest. “I mean, look at you! You’re so fuckin’ big and sexy, I could stare all day and never get tired.”
“Stop,” Brian replied with a laugh, unable to process such glowing praise.
“No, I’m serious!”
With that, Max shifted downward, climbing onto the larger man to straddle his thighs. He had to marvel at the enormously full tummy before him, placing his hands on either side of the dramatic swell with fingers digging into Brian’s fleshy sides. He then leaned forward to leave a trail of adoring kisses over every square inch of belly, lips brushing gingerly over smooth skin and circling the dip of the big man’s navel, the digestion process clearly audible with loud gurgles and groans coming from within. The further down Max went, the more give there was, and reaching Brian’s underbelly he relished the feel of pressing his nose against the soft padding he found there, breathing warmth across sensitive skin, absolutely lost in exploring the landscape of his partner’s body.
“Imagine making you even bigger, though,” he murmured, one hand finding the bulge of Brian’s cock and giving a few long, languid strokes. “So big you can’t even reach down here anymore...maybe if you're good for me, I’ll do it for you, just like this.”
A choked curse came from behind the bulging belly, and clear fluid dribbled down Max’s fingers, prompting a grin.
“You like that idea, fat boy?” Max purred, licking and nipping sensually along the curve of the larger man’s swollen gut. “You want to get even fatter for me? Let me feed you up like this all day, every day?”
“God yes, please,” Brian begged, bucking his hips into Max’s touch. “Please, I want you-- I need you to--”
Fuck me.
The words caught in his throat, replaced by a whine, but they didn’t even need to be said. He was far too full to be on top, of course, and though he could have been straddled and ridden with minimal effort, there was a look in his eyes that suggested something different. Max slithered away for the briefest of moments to grab lube and the second slice of cheesecake from the nightstand, with Brian hungrily watching his every move. The bigger man rolled away onto his side once he saw his partner lube up, then looked back over his shoulder impatiently, knowing he was getting exactly what he wanted.
Kneeling behind Brian’s back, Max fought to open the styrofoam container for a second, making it squeak and groan angrily, then gently tossed it in front of the other man’s face, letting him get the sight and smell of it to keep him occupied. Brian went one step further and leaned forward enough to take a big bite right out of the container, hands-free, devouring half of the slice in one fell swoop.
“Shit,” Max said under his breath, pausing with well-slicked fingers in mid-air to watch, impressed.
Brian looked over his shoulder once more and flashed a toothy grin, then went back for another, much smaller bite, snapping the slimmer man out of his daze. Stopping mid-chew, his breath hitched at the feel of a wet, cold digit worming its way to his back door, pressing in gently but firmly, and when another came to join it Brian couldn’t help squirming in place, rocking his hips back and forth. Max patted and pressed against the big man’s belly with his free hand while slowly working his lubed fingers in up to his knuckles, moving in and out, in and out, making sure he was well and truly primed for the final act.
“You really want it, don’t you, baby,” Max said in amusement, dripping lube all over his cock and making sure to swipe a little bit across the inner ridges for easier grinding. “You’ve been such a good boy for me tonight, you earned it.”
Shutting his eyes, Brian let out a needy groan, gripping the sheets tightly as the feel of an insistent, blunt pressure began to stretch him wide open. It was slow, agonizingly so, but he could already see stars behind his eyelids while Max took his time in plunging up to the hilt then back out again, testing the force needed to get the job done. Every thrust seemed more confident than the last, the pace gradually quickening once the perfect angle was found, and the textured ridges lining the back of the strap-on became even better than fingers against Max’s anatomy, which ached and throbbed with arousal beneath his altered briefs. He huffed and bit his lip, gripping the underside of Brian’s heavy belly for support, the little whines and moans he was eliciting becoming like music to his ears.
“Finish the cake,” he commanded between breaths, giving the big man’s gut a firm slap.
It was difficult to focus while getting pounded in the ass, to Brian’s credit. Still, he wanted to please his partner above all else, and despite his painfully full stomach telling him no, Brian tipped the container and grabbed the last of the cheesecake between his teeth, cheeks bulging while chewing quickly to get it all down. Rewarded with thin fingers around his neglected arousal, that plus the fattening sweetness in his mouth and the hard cock taking him from behind nearly had him short-circuit right there from sensory overload.
Keeping his hand loosely wrapped around his partner’s thick shaft, Max barely had to flick his wrist at all, the force of his hips’ thrusting doing most of the work-- he doubted the bigger man could handle much of this before being overtaken by climax. His inner muscles clenched as tightly as they were able, the lower half of his slender abdomen pushing inward, countering the overwhelming pleasure of the little nubs and ripples that ground fiercely against his sensitive anatomy with every thrust. He moaned, breathing hard, and now seriously doubted his own stamina as well-- perhaps that was for the best.
Brian had never felt so utterly full before, full in every way possible, and the absolutely overwhelming cascade of sensations from his belly to his backside threatened to drown him in a sea of pleasure. Clearly from the sound of it Max was enjoying this too, and it was the smaller man’s lewd moans rising in pitch toward orgasm that finally set Brian off, cock twitching and shooting cum across the underside of his bloated belly while giving a few erratic thrusts into Max’s hand. It felt like the wind had been knocked out of him, recovering from so much at once, and though he puffed and panted and floated mindlessly in the afterglow of such a satisfying climax, he dutifully grabbed Max’s slender wrist and redirected the hand from his softening cock to his aching belly, hoping it would coax his partner over the edge as well.
Smooth fat cushioning his palm and redirecting his mind’s eye to the night’s feeding session, Max slammed hard into his partner a few more times and got off with ease, every clenched muscle in his body finally releasing as one while his inner passage went wild in the throes of orgasm. He pulled out to ride the wave of pleasure to its end, then instantly wriggled out of his harness, discarding it and his well-used cock by the side of the bed in favour of snuggling up to Brian’s broad back to catch his breath.
Wrapping his arms around the much larger man for a cuddle, one would typically call Max the Big Spoon in this position, but considering their size difference, he likened it to being a Jetpack instead. Both men were perfectly content to stay put and recover without moving an inch, Brian teetering dangerously on the precipice of sleep with only the feel of absent-minded fingers playing in his chest hair tethering him to the waking world.
“Sweetie?” he eventually asked, continuing once he received a lazy noise of interest. “Did you mean what you said, back there? Um, the stuff about me...y’know, getting bigger?”
He could tell Brian was reddening just saying that out loud, and Max laughed into the back of his neck, giving him a few gentle kisses of approval.
“Yeah, absolutely. It’s your decision, Bri, but I’d be more than happy to help you grow, if you want,” Max replied truthfully.
With a hum of consideration, the bigger man carefully rolled over, letting his partner scoot out of the way so they could rest face to face on the bed. Only the sounds of digestion coming from deep within him punctuated the silence for a long moment, and he shut his eyes to enjoy the comfort of the gentle and appreciative belly rub he was granted, hoping the future would hold so much more of them, of this.
“We’ll see,” he said tiredly, nestling in against the shared pillow to finally drift off to sleep. “...You might get lucky.”
