Izuku wasn’t quite sure what to expect in bringing a rescue to his home.
While most owners would pride themselves in adopting a mixed breed of dog, or perhaps a stray cat; Midoriya had completely bypassed the beginners circle and brought home a fiery wolfdog hybrid with a bad temper.
To the adoption center’s defense, they did try and get him to pick an actual full animal, rather than the hyper intelligent and human-esque hybrids they sheltered. A lot of them, though rare as they may be, simply weren’t suited for the lap of luxury they were bred to inhabit. Or were byproducts of fighting busts.
That was the case of Bakugou Katsuki; or Kacchan for short.
At first the pet shelter didn’t even want to give him the snarling wolfdog, even with his euthanization date looming overhead. He just didn’t play well with other humans and animals.
A part of them must have known that the lonely college kid wouldn’t have any clue how to handle an aggressive fighter dog. Let alone one that could overpower him with ease. However Izuku was studying to be a veterinarian for a reason, and he had many sources vouching for his professionalism. He’s researched both pets and hybrids during his degree.
Though…textbook didn’t always mean guaranteed.
There wasn’t any part of a book that explained how to actually live with a pet, rather than just pointing out ailments and medical practices. Google quickly became Izuku’s best friend as he flipped through internet pages on all of Kacchan’s stranger behaviors.
He was often left even more confused than when he started.
The massive wolfdog had a knack for destruction; most times knocking over decorations, running himself into the furniture, and tearing it up with ferocious intensity. Izuku thought he was just bored and lacking energy and a suitable outlet; however he soon found out it was a sort of personal grudge.
Bakugou just hated him it seemed.
He’d piss on Izuku’s pillow, rip apart his couch, hump his cushion seats, and bulldoze the kitchen. It was notoriously hard to keep a bored and angry Hybrid out of rooms when he could easily turn the handles! The blonde was even smart enough to get through the marketed Hybrid-Proof locks he had purchased!
Blearily, Izuku realized for the fourth time that month, he may just be in over his head. Why he thought he could rescue a Hybrid and expect it to realize it was days away from dying was beyond him. They just didn’t think like humans. It was a well-known study and fact!
It still hurt that the other was so ungrateful.
Rubbing at his temples, Izuku sighed to himself, slightly tipsy off of his third glass of wine. His phone fell out of his hands with a dull thump, landing on the sheets when the last of his google searches came up fruitless. He didn’t know what he was hoping for at this point. All hybrids were different, and Kacchan just had his own personality that didn’t match the typical.
He had been up late cleaning up the wolf’s latest mess; another round of destroyed pillows. It was always like a bomb went off in his living room every time he came home. At this point he didn’t even care to pick up the mess beyond cleaning up any glass. It was just too expensive for a college kid to keep replacing things.
Izuku could deal with the mess, deal with the temperament of the blonde; but one thing he was sick and tired of was being unable to even bring his ‘friend’ Shouto around.
They were in the same general education class, though he was intending on escaping his father’s plans to put him through business. Hell it was even Izuku who inspired him to follow his own path. Throughout their crazy adventures through math and sciences, they grew close, often close enough to warrant a more unusual friendship.
Well. More of a friends-with-benefits.
Midoriya never had to remain unsated for long with Shouto’s thick cock at the ready to please him. It was a godsend for every T needle he injected, feeling his arousal spike with the steadily increasing dosage as of late. A single call was all it took to have the attractive man at his command-
Except Kacchan hated Todoroki. Hated him with every single fiber of his being.
Any sight of red and white and he’d snap, lunging at the man, threatening him with teeth and ire. It’s made it pretty hard to meet up with the other when he wasn’t saying in the commons.
Leave it to the rich guy to afford a penthouse on his daddy’s spending money, one on the other side of town, which made it impossible for him to get there and back. Y’know- considering he didn’t have a car. Life just wasn’t fair for Midoriya lately. All he needed was a good lay and he swore he’d have the energy to deal with Katsuki’s messes.
Pulling up his browser for the fourth lonely night in a row, Izuku hunkered down in his sleepwear, feeling the exhaustion of tomorrow’s test looming.
Idly his thumb flicked through various videos with lackluster enthusiasm; each far more boring than the last. It appeared as though his options were severely muddled down with garbage today. Porn was never easy to scroll through, yet today it just kept grating on his nerves! He was buzzing with anticipation and energy beneath his skin, yet in the end, there was nothing substantial.
Consider him a bit picky, but Izuku never really clicked on anything unless everything about it seemed good. The thumbnail, the description, the little five second tidbit- if he was going to watch porn then it would be worth his time in the end.
He kept searching until a stock of blonde hair and muscles caught his eye.
Lazily Izuku hovered over the image, titled ‘Blonde stud with tattoos utterly ruins twink partner’. Midoriya could appreciate what he saw. The man was all muscles, though not to the point where it overtook his form, and didn’t hesitate to show that off in the thumbnail.
The man beneath him was utterly unforgettable as Izuku clicked on the video.
He worked his lower lip between his teeth as the handsome man pushed the other onto the bed, clearly being rough with him, despite the skittish personality to the submissive actor. Izuku liked that a lot. His fingers traveled up and down his naval as the kissing became more intense onscreen. He could appreciate the aesthetic of the duo in action.
Only when the dominant figure began to palm at their sub did Izuku finally stick his hands below his panties, hiking up his tank top enough to give him plenty of space. He had wanted to feel sexy tonight; so lacey underwear it was.
Shame nobody was going to see it.
He bitterly mused this even as the video played on, wanting nothing more than for Shouto to be here right now. His fingers just didn’t feel the same as they teased his clit, the flesh swollen and solid beneath his fingers. The sounds he wanted to make were locked in the back of his throat, chewed into silence between his teeth.
When the blonde finally managed to work his way inside of the other? Izuku’s fingers slid downwards, allowing his pointer and middle to stretch him wide open. The ache burned so good inside of him, making his toes curl and back arch, until he was practically panting in need. God that felt so good. He could put his bitterness at masturbating alone aside for now.
The actor’s cock looked so thick and inviting, with plenty of appreciative pans over his sculpted body and tattooed arms to match.
Izuku humped down onto his fingers when the building need mounted into a full blown desperation, his toes scrabbling for purchase on his sheets the longer he finger fucked himself. As much as Midoriya wanted to savor the feeling like a slow banquet, he just wasn’t capable of it, cramming in a third finger as the scene reached its climax.
Seed dripped out from the submissive’s ass for the very last shot of the movie, the tattooed hands of his dom spreading him wide open. Izuku mewled at the thought of that being him.
That was one thing Shouto couldn’t give him; creampies. No matter how long he was on Testosterone, nor how effective Plan B could be, he couldn’t let the man cum into anything else besides a condom or across Izuku’s back. It was disappointing but not worth the risk of pregnancy in the slightest.
The afterglow was short lived as reality caught up to Midoriya- feeling his fingers come back coated in slick and juices. Eugh. Even his panties were uncomfortable on his body as he let his thighs fall back down to the bed. He didn’t care today, choosing to wipe the proof of his actions against the side of his sheets. He’d wash them tomorrow, he mused, while leaning over to click off the light and go to bed.
The human nearly jumped when red eyes were staring at him from the side of the bed, watching, with that ever present scowl on the wolfdog’s face. Midoriya had to catch his breath when he realized Kacchan had just snuck into his room sometime during his debauchery.
“You scared me, boy!” the man whined, instead clicking off the light when he was sure Katsuki was going to remain hunkered down on his adjacent doggy bed. Strange. Usually the dog couldn’t be caught dead sleeping in the bed Midoriya poised next to his own. It was a small victory to notch under his belt tonight.
Izuku’s smile remained soft. “Goodnight, Kacchan.” It was a lazy murmur more than anything, his eyes grown heavy with the deadline of tomorrow’s alarm looming overhead. Even if he didn’t get a lot of sleep tonight he knew he could ace the test.
He heard a small huff before the world faded out around him.
- - - - - - - - - - - -
At first he wasn’t quite sure what he was feeling.
It started out as a trickle of sensation reaching his upper brain, lulling him from the deep slumber he had once resided in. Izuku couldn’t really pinpoint what it was. His body felt like a strange combination of overstimulated yet far too lost to understand it. Was he even awake, or was he still asleep?
His eyebrows pinched together when sound sought him out next- a wet and sloppy noise making him cringe.
His vocals were heavy and laden with sleep as he made a halfhearted noise, a sudden douse of discomfort making him shift. Oddly enough though was how his body refused to so much as budge. There was a weight holding him down- and that was enough to make his eyes snap wide open as a surprised gasp left his lips.
Izuku couldn’t catch his breath fast enough; let alone comprehend what was going on around him. His mind raced to the thought of intruders, of robbers, of every worst case scenario that could possibly happen to him.
He shot up with nerves shaking him to his very core, only to hear a low growl that paired with such a…familiar…sensation.
His mind short circuited as exhausted green eyes flickered to below his waistline, the covers having been pulled off of him a long time ago. His sleep addled brain moved slowly to dissect the scene before him. Kacchan was knelt between his legs, up on the bed, with his nose buried directly between Izuku’s thighs.
The hardest thing for him to grasp was the mind-numbing pleasure radiating from his lower abdomen.
His thighs shook fiercely where they were clamped within Bakugou’s aggressive hold, the massive hybrid knelt between his legs and lathing his tongue in Izuku’s most intimate place. Judging by the combination of drool and slick running down his thighs? He had to have been at it for quite some time.
It felt sinfully good, to have a skilled tongue sweeping over his clit in lazy laps. His wolfdog knew what he was doing as he wrapped his lips around his clit to suck.
The thought was horribly conflicting. On one hand he had a hybrid, a half human and half animal, lapping at his cunt like it was the best meal. On another? If he really squinted…Kacchan kind of looked like the man in the porn video.
The same cocky smile, the same lift to his eyebrow, same wild and untamed hair; Izuku’s pussy betrayed him by clenching down harder as Bakugou’s tongue flicked over his clit.
If it weren’t for the dog ears atop of his head, would he really be anything different than a beddable man?
The taboo still lingered as Izuku remained frozen, neither pushing nor pulling Katsuki away as he ate with a blatant desperation. The snarls and huffs against his wet skin made Midoriya shudder at the filthy feeling between his legs. Oh god, he was letting Kacchan eat him out. It inspired Izuku to lightly grip the wolfdog and attempt to guide him away-
Those sharp teeth quickened his pulse as Bakugou’s nails dug into his thighs, forcing him closer in order for the man’s whole mouth to encompass Izuku’s soaking pussy. The other could sob at how good it felt for the Alpha to eat him out like this.
His thighs trembled as the stimulation mounted to an unbearable itch. Even if he stopped the blonde now, there was no way Izuku could tolerate being so close to the edge and denied release. This was the closest to a satisfying orgasm he’s been in nearly a week.
Even with the shame burning hot on the back of his neck, he let his legs splay wider to Kacchan’s advances, eyes closing tight as the looming pleasure swallowed him whole.
His back snapped into a perfect arch when the mutt’s thick tongue pushed inside of him, lapping wetly at the plentiful juices flowing out of him. His scream fell muffled as he clamped his hand over his mouth. Even if he lived in a single room dorm with no roommates, he had to worry about the neighbors next door.
That had to be the strongest orgasm Izuku’s had in a while. His thighs were jelly when they fell off of Kacchan’s shoulders, the red eyed hybrid staring down at him with a mixture of trepidation and interest.
His mouth was coated in Izuku’s juices. He licked his lips with a slow roll of his tongue, savoring what was left, until the wet discomfort below Midoriya’s hips caught the human’s attention. He stared down at the massive wet patch that certainly hadn’t been there before. His body tensed up at the epiphany- he had just squirted.
Shouto had only been able to do that once.
The revelation came slowly, addled down by his post orgasmic haze. Not only did he just squirt, but his body was completely relaxed and sated, leaving him with the most pleasant afterglow as the wolfdog settled at his feet. It all made too much sense.
Of course Bakugou would want to chase Todoroki away; he had to be experiencing sexual aggression. An Alphan mixed breed with a naturally bad temper? He’d be sexually aggressive.
Thoughts raced through Izuku’s mind as he rolled over onto his stomach, tangling his legs up within the sheets, attempting to escape his own mess. Blearily he threw his panties off when the soaked hem had only grown cold. Kacchan was aggressive, but maybe getting him a mate or studding him would effectively calm his anger?
Izuku reached to feel around for his phone, furrowing when he couldn’t locate it. He knew he had left it on the sheets last night.
He wanted to Google this now- maybe see if there were any resources for Hybrid Breeding or sexual health anywhere? It couldn’t be too farfetched to assume that they existed! His phone evaded him no matter where he slid his palm, feeling a rising frustration at the realization it must have fallen between the bed and headboard again.
His knees were like jello as he hoisted himself up, angling his body downwards in order to feel between the crack.
Izuku froze when an excited growl met his new position. Before he could try and scramble away, Kacchan had approached, nose shoved in Izuku’s pussy as his eager hands came to lock the human in place. He threw himself over his owner’s back with a pleased huff, Izuku’s mind drawing a blank when the rough claws of the other dragged him back.
Oh god. No matter how he squirmed and kicked, Kacchan wouldn’t get off! The wolfdog’s hips lazily humped forward as he attempted to find the source of heat radiating from Izuku, snapping his teeth in warning when Midoriya tried to rolled away.
“De-ku,” he snarled, throat constricting around the syllables with effortless ease. It mixed with the growl in a way that really shouldn’t have gone straight between his legs like that.
He was weak, so weak, as Kacchan’s thick cock began to rub at his folds. He was getting closer to the mark with every quick hump of the other’s hips. Meekly Izuku bowed his head when Bakugou’s hot breath began to fan over the back of it. He was so weak- he couldn’t help but spread his legs just a bit wider when the head of his cock finally caught between his folds.
At first the sensation was kind of uncomfortable- Bakugou just couldn’t find his hole. He was so big compared to Izuku that his mark was off. The rising frustration on his end had him snarling and panting into Midoriya’s ear, clearly irritated as he shifted to find a better angle.
Finally Izuku caved, head resting against the headboard as he arched his hips into the stimulation. Oh fuck, nothing could compare to the feeling of Kacchan finally pushing the head inside with a broken thrust. His cunt ached around the stretch, unused for the last week, yet easily accommodating for the space it wished to carve inside of him.
Bakugou was big
“Kacchan-!” he moaned out when the wolfdog’s hips began to hump, strong arms keeping him in place as he pushed and pulled Izuku to his solid body. Midoriya’s limbs melted easily into the motions. His ass slapped against Bakugou’s waist, knees pushing him back into the firm stimulation rocking him to his very core.
While Todoroki made for a delicate and attentive partner? Bakugou didn’t care for finesse. He just thrusted and took as he pleased, yanking Midorya to his hips and sending him forward again from the sheer power behind his thrusts.
Izuku saw stars.
His moans came in broken intervals as Katsuki mouthed and bit over his neck and shoulders, at times even latching on to hold him steady when his pace picked up. Midoriya mewled with every merciless drag that his wolfdog took. He didn’t mind the slobber, didn’t mind the mess, not when his cunt was being fucked so good.
Eagerly his fingers came back to run through spiked hair, loving the broken warble that came from Bakugou’s throat. The hybrid’s hips picked up as Midoriya scratched and tugged at the spiked locks, feeling his pussy clamp down around the intrusion as it spurred Bakugou to a faster pace. Now their bodies really met together; sparks flying behind Izuku’s lids.
His body struggled to keep up with the change. He turned white-knuckled from how firm he had to grasp Bakugou, the mixture of slick and precome entering him making him giddy.
“Good boy,” He panted out in the moment, feeling the wolf’s ears twitch in his hand. Kacchan’s efforts practically doubled as he shamelessly continued, a pleased grunt coming from him as the praise flew right over his head. Literally. Izuku was moaning like a bitch in heat as he pushed himself back against Katsuki, hands scratching at the sheets for support.
“Oh god, you’re such a good boy.”
Bakugou’s whine was cut off as he felt fingers probing where their bodies met, watching as his master came undone beneath him. He loved seeing the debauched expression on Izuku’s face, cheek pressed to the headboard, while a mixture of drool and tears leaked down his chin. He was always such a crybaby even when happy.
It did something fierce to the wolfdog’s ego as he watched Izuku come undone beneath him, his fingers rubbing at his clit, chasing his own pleasure at the pace which Katsuki took his.
The warm walls of the human kept clamping down around Bakugou, making him grunt each time it felt as though Izuku wanted to swallow him down. They were both getting close. Midoriya’s pussy sobbed around his knot, leaking fluids as Katsuki’s pre kept filling him up. They were both a mess. The hybrid’s knot had started to inflate by the time that Izuku’s entire body trembled in pleasure.
“Come- I’m gonna come, oh god Kacchan. I’m gonna come!” he kept moaning, his fingers struggling to keep grip on Bakugou’s head. Two orgasms in such a short timeframe? The man was on cloud nine as Kacchan kept fucking him, the base of the wolfdog’s knot continuously catching on his rim.
He’d never felt a knot before. It was basic hybrid anatomy, and yet, the thought never occurred to him until now that it actually could catch on him. He hadn’t exactly spent his time fantasizing about fucking his hybrid.
The stretch was positively divine as the Alpha kept up the pace, his panting turning uneven and labored.
All it took was one bite to his shoulder and Izuku was squirting again, his body shaking from the strength of his release. He felt the contractions of his pussy attempting to milk Bakugou, as though on second nature, knowing that there was no buffer between him and the hybrid’s cock. When Kacchan came he would be filled-
He mewled in delight when the last push sent him higher, the Alpha’s knot forcing its way inside for another burst of stimulation. Izuku couldn’t, for the life of him, manage to come a third time. As tempting as it was, he kept humping back on Kacchan’s knot, loving the catch and drag as the sharp teeth in his shoulder ground together.
The warm twitch of the wolfdog’s cock felt so sinful inside of him, painting his insides with thick ropes of cum. The knot throbbed with each spurt that left it. Izuku’s fingers were already dripping in sticky seed as it spilled out around him, his anatomy unable to keep semen inside like an Omega could. It only added to the satisfaction as he rubbed and smeared his clit with the fluids.
By the time Kacchan was done, Izuku had slumped down, his hips the only thing remaining elevated. That was the best sex of his entire life.
The human whimpered pathetically when the knot slipped out- much to Katsuki’s own distaste. He whined and growled as he had to cup himself, hating how his sensitive knot was exposed to air like this. Usually his own species would clamp down and ensure a tie.
Izuku’s sloppy pussy had made sure he fell right out with the slightest of twitches.
Bakugou stared down at the blissed-out mess his owner had become, grumbling in irritation at the mess he made. Even the wolfdog’s fur was matted down with how much slick Izuku produced. He flopped down on the mattress next to his incompetent human, nosing at his palm while Midoriya shuddered from the aftermath.
Warm seed spilled out of him in steady rivets, his gaping hole clenching around nothing. His thighs shook from exertion as he weakly shifted, moving to wrap his arms around his Kacchan and settle into the Alpha’s chest. Damn humans and their cute clinginess.
Katsuki could put up with the gentle pets through his hair, or the way that Midoriya knew exactly how to pet his ear to get his tail wagging. It was just a little bonus to rutting such an inferior creature. He’d put up with it, finding that he wasn’t quite as hostile towards the stupid human anymore. Must just be because he could take a knot so well.
He settled down at Izuku’s side, cringing at his sore knot finally deflated and retreated back into its sheath. Bakugou had to admit; it was a fun round. It had been so tiring smelling the constant arousal wafting from the other.
“Who’s a good boy?” Izuku asked lazily, as though to fill the silence. Still, Bakugou couldn’t control the thump of his tail, feeling the same buzz of contentment his master did. He was a pretty damn good boy.
Maybe, just maybe, he’d stay that way if it meant getting his human to bend over.
