Katsuki always hated his new home. Back when he was in the fighting ring, despite the small kennels and the very real possibility of death, he always knew what to expect. He was kept to a very strict routine to keep him in peak shape. His owner expected him to win, and win he did. Fighting was what he knew, deep in his blood. He was
bred
to fight.
The worst day of his life was the day the cops stormed the fighting ring and seized all the fighters, himself included. He didn’t know what happened to the others—didn’t really care—but not being in his familiar home had him on edge. He was so used to tight quarters and dark rooms. The idiot officers failed to take that into account when they dumped him off into the hands of this shitty big cat sanctuary.
His enclosure was open, spacious. It was meant to emulate his natural habitat. It set him on edge.
Not to mention the fact that after only being here for less than a month’s time another cat had been shoehorned into his pen. Another
alpha cat,
at that.
Katsuki had watched the bobcat roam around his space like a hawk, growling whenever she got too close to his marked territory and ready to fight should the need arise. The bobcat—Ochako, they called her—kept her distance for the most part. They never fought for food due to their differing size; Ochako feasted on smaller birds and rodents, while Katsuki feasted on deer and rabbits. The bobcat preferred sleeping in one of the many holes that lined the rocky wall, while Katsuki preferred his spacious cave. They stayed on opposite sides of the enclosure.
Yet the bobcat’s presence still made him uneasy. Despite the sizable territory they had each claimed as their own, he could still smell the bobcat’s strong alpha presence. Worse yet, he could feel the other’s big brown eyes staring down at his cave from high up.
Tonight was no different.
Katsuki could feel the gaze of the other cat more intensely than any other night. He was going to be entering his rut soon, which would lead to an inevitable battle of dominance with the other alpha. Katsuki had no doubts he could easily overpower the smaller cat, but he wasn’t sure if he could hold back once he was truly lost to his instincts.
Katsuki curled further into himself as heat began to flicker through his body. He always hated when his ruts kicked in. Since he’d been the top alpha hybrid of his fighting ring, he’d been expected to mate to ensure his fighting genes lived on. He’d been expected to, but no omega he fucked had ever gotten knocked up. Something about his sperm count being low or whatever bullshit the human doctors fed his owners.
Then had come the drugs—dozens of different I.V. drips poked into various places of his body in order to pump the mystery liquids inside him. It’d hurt so badly, burned him from the inside out. He’d screamed until his throat was hoarse and his voice was shot. After being hooked up to the drips for three days, he’d finally started to feel the effects of them. His rut had been artificially induced and was several times stronger than it ever was previously. He doesn’t recall what happened after that, but what he
does
know is that they never asked him to knock up an omega again, and all his ruts were much more intense from then on.
Katsuki huffed as the heat in his body began to pool in his groin, forcing his cock from its sheath.
His previous Masters may have never asked him to mate again, but they were far from relenting. They’d artificially induced his rut many times just before a match to dull his human side and bring out his more “beastly” side, as they referred to it. Those fights always ended in bloodshed.
Some had even ended with bloody shreds of a neck hanging between his jaws.
Katsuki rolled onto his back as his tail thumped wildly against the floor. His cock steadily filled with blood as his body’s arousal rose. It stood proudly in the air as if begging for him to find a willing mate to sink into and knock up with his cubs. It wouldn’t be too much longer now until the urge to mate became too overwhelming.
After what felt like hours of staring up at the ceiling of his small cave, he turned onto his stomach. The arousal flowing through him was beginning to turn painful.
Katsuki reluctantly snatched up a pillow from his sleep pile and shoved it under his hips. He hissed as pleasure surged through him from the newfound friction against his dick. His hips quickly found a rhythm rutting against the soft surface.
Images of past omegas he fucked filled his mind with their soft hips and large breasts, asses presented and ready for him to fill with his pups. His cock only barely twitched. None of those supposedly extra fertile omegas ever ticked the boxes of what really turned him on. They weren’t battle born and covered in scars. Their bodies were supple and soft instead of rough and hard. They lacked a willingness to fight back.
They weren’t like the brown haired bobcat.
Katsuki growled as the realization that he might actually be
attracted
to the other wildcat in his enclosure washed over him. He humped the stuffed pillow faster, desperate for any sort of relief to the growing pain. His mind provided him with images of his past matings with the bobcat in place of the omega. It made his cock absolutely
throb
with pleasure.
Katsuki sunk his teeth into the edge of the pillow to stifle any noises lest he wake the night guards. His orgasm came and went as if he hadn’t done anything, leaving him substantially more horny and with a sticky mess on his favorite pillow.
He tossed the now ruined thing towards the corner of his cave and decided to spend some time basking in the sun before his rut inevitably became substantially worse. Katsuki stretched his limbs as he walked, eagerly awaiting the warmth the well-heated rocks would offer.
The breeze of the mid-afternoon day sated the fire that blazed within him only for a moment before the scent of a competing alpha rut filled his senses. Shoulders raised and tail puffed, Katsuki stalked through the short shrubbery and neatly kept trees of the enclosure until he found the source of such a fierce scent.
His roomie, that damned bobcat, was humping a green stuffed rabbit into the ground so harshly it looked like the seams were about to split and spill the innards out on the dirt. The bobcat caught his challenging gaze and didn’t drop once, not even when her orgasm hit and her small cock twitched out a few thin lines of cum onto the bunny’s soaked fur. She stood to her full height, barely reaching his chin not counting her ears, and growled deep in her throat.
Katsuki responded with a growl in kind, ears flat against his head as his tail flicked side to side in agitation. The bobcat’s ears pressed flat against her skull as the fine hairs on her body stood on end.
For a moment, they both stood still sizing each other up before the battle for dominance began.
In the end, it was Katsuki who made the first move. He pounced on the bobcat, knocking her down to the ground with a loud thump. He kept her shoulders pinned down and hissed. The hiss was returned. Katsuki ignored the smaller’s thrashing in favor of wrapping his jaws around the other’s throat in a loose but threatening hold. He hoisted one of the bobcat’s legs around his waist while keeping her chest firmly in place with the other.
Blindly, he began thrusting his now aching cock against her slick hole. The stimulation felt heavenly against him, but he wouldn’t allow himself to get lost in the sensations when he had to establish himself as the true king.
“Bakugou Katsuki,” he chuckled darkly down at the bobcat who stilled momentarily as he spoke for the first time since arriving at the sanctuary. “Burn the name of your new alpha into your skull.”
His words seemed to set off a fire within the other as she started fighting his grip harder than before. He had to give it to the bobcat—she packed some serious hidden muscle—but his long reign as the champion in the ring wasn’t earned through match fixing.
Katsuki kept his hold on the other, even going so far as to dig his claws into her skin to maneuver her better as his cock finally caught on the rim of her cunt. He bottomed out with one solid thrust, moaning as her tight walls pulsed around his steadily growing member.
“Be good for me, Round Face, and I won’t be so rough next round.” Katsuki teased as he lapped at some of the sweat that had begun to form on the other’s neck.
The bobcat growled as he set up a rhythm, grasping at any flesh her tiny little claws could reach. The scratches stung, but Katsuki could hardly care. The feeling of being sunken into such a tight and already soaked pussy overrode any pain he might have felt otherwise. He retracted his teeth from her jugular so he could place feather light kisses up and down her jawline in hopes of calming her down.
But his plan backfired—the bobcat seemed to be more fired up than before.
She let out her most feral growl yet and managed to throw Katsuki off her. Before he could reorient himself, the bobcat was on top of him and already lining the head of her tiny cock up with his asshole.
Katsuki hissed at her.
“Don’t you fucking
dare
Round Face.”
The bobcat ignored him in favor of shoving her leaking dick in to the hilt with one swift movement. Katsuki shrieked as the pain from the forced intrusion threatened to swallow him whole. She began thrusting without waiting for him to adjust, looming down on him to force his attention onto her.
“My name is Uraraka Ochako. Not ‘Round Face’. Learn it, Katsuki, ‘cause I’m not going down without a fight.” She huffed, ears flattening even further against her skull as a small moan left her lips.
If Katsuki wasn’t being overrun by his instincts to make the other alpha cave in to him, he might have found it adorable. Sexy, even.
Instead it makes him writhe with the need to turn the tables in his favor.
Ochako moved her lips down to his neck and kissed his Adam's apple once before taking his jugular between her teeth in a mockery of what he’d done to her. She sped up her thrusts, purring with each time she bottomed out.
Katsuki moaned when she changed the angle just enough to tease that special spot inside him that made him see stars.
“You’re mine, Katsuki.” She whispered against his skin, hammering against his prostate with every movement to draw out a forced orgasm and bring him to submission.
Just as he reached the cusp of orgasm, his vision turned red as his instinctual need to dominate the other kicked in.
“I won’t lose to you!” Katsuki yelled. With a sudden surge of adrenaline, he flipped their position and forced the intruding member out of his ass.
Katsuki plunged his cock into the bobcat for what he hoped would be the final time, grunts and growls picking up in volume with each thrust. Ochako began moaned as he fucked into her, legs coming up to wrap around his waist as she exposed her neck in submission.
Katsuki purred in delight over winning their dominance battle and decided to give her a more human display of affection. He crushed their lips together in a bruising kiss as his hands found their way to her hips. She parted her lips to allow his exploring tongue access.
Katsuki picked up the pace until it was borderline painful for them both as he eagerly chased orgasm. Ochako came first, gasping as her tiny cock spewed cum while her cunt clenched around him like a vice. Katsuki fucked her through her orgasm and nearly screamed when his own hit.
Waves of ecstacy like no other flooded his veins as his barbs caught on her walls and forced her to bear all his semen until they went down. He collapsed onto her chest once fully spent, limbs exhausted after their fight.
Ochako wrapped her arms around his chest and pulled him as close as she could, burying her face in his shoulder.
“I like you,” she said shyly.
Katsuki laughed. “I think I’ll like rooming with you from now on, bobcat.”
They lay in silence together, waiting for the moment Katsuki’s cock was ready for their next round since both their ruts were still raging. Just as Katsuki was about to kiss his new mate again, the door to their enclosure opened and startled them.
“Katsuki, Ochako, come meet your new roomie!” Both cats looked up at the same time as an unwanted wildcat walked in, raising both of their hackles. However, their growls died on their tongues as their new roommate made himself known with a deep, rumbling purr.
Oh, fuck no.
“Meet our newest rescue: Izuku, a tiger hybrid!”
