“Alright class, bring your most recent screenings up. I’ll check them before we start.”
Katsuki groaned softly, feeling his head bob back and forth as he distantly heard his master’s voice. His brows furrowed as panels of bright lights seeped through his closed lids, only relaxing back into the comforting waves of sleep when a hush soothed his ears.
“Good boy, Kitten. Good boy, just relax…” Aizawa cooed, Katsuki barely registering the warm calloused fingers scratching behind his fluttering ears.
“Today will be the practical portion of this week’s lesson," Aizawa continued to drone, his words incomprehensible in Katsuki’s sated state. “As decided last class, Yaoyorozu will demonstrate the techniques of inducing arousal.”
Katsuki had half the brain to whine at his owner’s words before a floral scent hit his nose accompanied by overwhelming warmth spanning his back. The plush softness of breasts. His nerves settled, sandwiched between gentle reassurances and lithe palms, uncaring of the second voice that spoke up.
“I’m running my fingers along his inner folds, following them up to his clitoris, avoiding direct contact until the area is engorged and he is wet.” The voice finally reached his ears, a slow burn of panic ran up his chest with the dull awareness of a foreign touch. Soft pads toyed with his lips, tracing a figure eight along the expanse of his cunt, deviously ignoring his clit. Slick coaxed to dribble from his hole.
“W-Wait! Who–” His legs twitched, aching to shut on the hand assaulting his heat if it weren’t for the crimson ropes restraining him in a frog tie. Shaking ruby irises darted across the room, his mind reeling as the woman in front of him made quick work of sliding her fingers into his lubricated hole.
“Katsuki,” the woman called out to him in a stern voice, piercing stone-gray eyes staring down at him. “Behave. You want your prize, don’t you?” She questioned, pulling phrases from a lesson prior to entice obedience as her bare chest shone. Sizable, purple objects manifested from her cleavage. A choked groan left Katsuki’s lips as he watched two silicone dildos sprout from her skin, marbled like a galaxy and bumpy, one significantly larger. The toys quickly followed by a small slab of pink silicone, textured like tentacles.
A familiar voice chimed behind him, “Behave, Katsuki,” the voice sang almost hypnotically.
Tears pricked the hybrid’s eyes as he craned his neck back, “N-Nemi… d-don’t let her do this to me,” he panicked, attempting to kick his legs to get closer to his trusted sitter.
“It's okay, sweets. Be good and take it like you’re told.” Nemuri hushed, running her fingers through blond locks, releasing a small amount of her quirk to calm his nerves, her only role being to attempt to coerce him into a more relaxed state.
Blood drained from his face as he felt the two cocks prod at his holes, already strapped into the harness that sat snug around Momo’s hips, the tentacle grinder presumably tucked between the strap and her own cunt. Whispers of attempted praise slipped from Momo’s mouth as she began to push in, Katsuki’s unprepped hole struggling to give.
“That’s enough, Yaoyorozu. If you wanted to fuck something you should’ve stayed home with your own hybrid. Eighty-five points for arousal technique, fifteen marks lost for lack of prep and failure to subdue him. Shinsou, Togata, next.” Aizawa’s voice sounded far away, Katsuki feeling exiled as the warmth left his body, the cold table top was all he could feel as his legs were untied.
“Katsuki,” a husky, unfamiliar voice called out to him, “Are you ready to be brainwashed?”
The hybrid whined as he felt rough hands run up his thighs. He wanted so desperately to roll over and ignore everyone. His weak ‘no’ brought a small mercy as the touch against his skin vanished.
“That’s too bad.”
As clear as a pin falling onto linoleum, the voice pierced through Katsuki’s head. He felt the drum of his heart in his throat, a cry trapped, his body not letting him so much as swallow his fear as he was truly frozen.
“Get on your hands and knees,” the voice commanded. Like he was programmed to follow, Katsuki rolled over, holding a stable table-top position, unable to comprehend the clear, blue eyes and wide smile that was level with his face.
“Hitoshi’s being so mean to you, isn’t he?” The lips in front of him moved and though not a single word penetrated the surface of Katsuki’s brain the hybrid nodded. “That’s okay, baby. Daddy will take care of you.” He said, somehow clearer this time.
Katsuki felt ghost touches across his jaw, so light and gentle that he wanted to lean into the hand, the simple touch making him forget the compromising position he was in.
“Open that pretty mouth for Togata,” Hitoshi instructed, his voice hard in comparison to Mirio’s. Katsuki parted his lips as far as the thumb between his molars allowed. As quickly as it came his safety net was ripped out from under him as he slowly gained some consciousness, with that was the realization that Togata wasn’t there to help him. He was there to use him like everyone else.
“He’s getting angry,” Togata snickered, towering over Katsuki while he slowly inched his cock through glossy lips. “Are you losing control, Hitoshi? He looks just about ready to bite my dick off,” Togata chuckled, thumbing the creases between Katsuki’s furrowed brows.
Katsuki tried with all his might to steel the joint of his jaw, causing him to realize that he had more control of his body than he thought. Jumping at the opportunity, he slammed his jaw shut, squeezing his eyes for the consequences of his violence until nothing came, the weight against his tongue gone.
“See?” Togata laughed. Katsuki’s eyes snapped open, confused as to how his nose was buried in a clean patch of hair when there wasn’t a trace of Togata’s cock on his taste buds.
“I don’t like my hybrids bratty,” Hitoshi gritted, “I want him to understand who’s in control here. And you understand that’s me, right, Katsuki?” He asked with a yank of Katsuki’s tail.
Pulling Katsuki out of his frozen confusion, a muffled yell came from the hybrid, and just like before, lucidity was torn from him. From then on Katsuki’s memories became spotty.
One second his throat was filled all too quickly, Togata’s cock appearing out of thin air before the man violently fucked his face. Another second he was on his back, Hitoshi allowing him clarity with a slap against his poor, puffy pussy. He had no recollection of his legs being thrown over Hitoshi’s shoulders, just the torturously long minute of the man’s monster of a cock splitting him open, thrusts punching him in the gut as he was forced to watch the bulge in his belly jump in sync with Hitoshi’s hips.
All he could remember was the way he threw his head back in ecstasy, distantly hearing himself beg for reprieve. Every time in a different position: his back pressed up against Hitoshi’s chest with his legs pushed up to his own. His cunt suffocating Togata, crying with need when that devilish tongue would disappear and reappear so suddenly. He couldn’t forget being sandwiched between them, both of their cocks jamming up into his tight hole as euphoric tears hit Shinsou’s tongue.
By the time they were done, his cunt ached and his jaw throbbed as they left him defiled and dripping. His holes gushed with his own fluids, tied condoms uncomfortably cushioning his body from the hot, sticky exhibition table. Emptiness filled his eyes as his limbs hung off the edges.
“I love my toys dumb and broken.”
Katsuki paid no mind to the last student of the day, the top scorer rewarded with a nice, pliant kitty.
Maybe he’d disobeyed Shouta. Maybe this was his punishment.
No… he must have been the best kitten if his master decided to give him such a special treat. That’s right, his master wouldn’t hurt him. This was a reward.
A dopey smile graced his lips as he thought about how kind his master was. He shouldn’t have refused everyone, he should have been saying thank you.
Shindo cooed at Katsuki’s air-headed expression, “What’s got you so happy, Katsuki?”
Ignoring the creak in his jaw, Katsuki parted his lips, “More… please.” The pleading stretched a smile across Yo’s face.
“Do you know what my quirk is, angel?” Shindo whispered just loud enough for Katsuki to hear. Receiving a hum of disagreement, he chuckled. “Do you want to find out?”
The stupid grin never left Katsuki’s face even as he was truly pushed to his limits, overstimulation barely enough to describe the abuse his cunt went through. He’d figured out what Shindo’s quirk was when he was pulled to the edge of the table, the student burying his oscillating tongue in the kitten’s swollen cunt.
He tried so hard to take what he was given and be good, but the scratch marks he left on Yo’s chest only goaded Shindo on as he sat perched on aching knees, the cock inside him barely shaking with enough stimulation.
“Can’t… feel… it…” Katsuki moaned feebly.
A dark chuckle left Shindo’s lips, fanning across Katsuki’s ear as he pulled the hybrid down. “If you want it so bad, then ride.” Yo poked, minutely increasing the strength of his vibrations as an incentive. Driven by the heavy weight in his cunt, Katsuki ground down slowly. His muscles burned and his shallow bounces weren’t nearly enough to push him over the edge. Shindo motivated him, upping the frequency like a short shock, turning his quirk off the second Katsuki’s hips stop moving.
Overwhelming power filled Shindo’s chest. Katsuki was truly a sight to behold. A sinful mess of squirt and drool. God, he wanted to make Katsuki cry, show everyone that he was able to make this pretty kitty submit like they’d all failed to do.
Focused on the prize, he didn’t realize how close he was to his own climax. His hips snapped up to meet Katsuki halfway, his quirk going haywire until it shook every bone in Katsuki’s body. He cursed in pleasure and disappointment as he shot strong strings of cum into the damned condom. Fuck, maybe it was much harder to tame a slutty kitty than he thought.
Yo was still boneless and panting on the podium when Aizawa stepped forward for the first time since the start of class.
Shouta stepped up to the table, slowly peeling his clothes off, almost making a show of leisurely folding them, chuckling as Katsuki’s body moved on its own. The hybrid scrambled to his knees to nuzzle his forehead into his master’s bare chest, licking his lips as he eyed Shouta’s throbbing cock.
“Thank you for my prize, Master.” Katsuki trilled with a delirious grin, though Aizawa knew his kitten enough to sense the underlying need.
“Tell me what you need, Katsuki.” Shouta whispered, brushing slick bangs from Katsuki’s sweaty forehead, rubbing comforting circles into the kitten’s back with his unemployed hand.
“Inside… empty…” Katsuki whined, arching his back in search of Aizawa's cock.
“Empty? Even with all that fucking?” Aizawa hummed as he trailed his hand further down Katsuki’s smooth skin, leaving an appreciative grope on his kitten's ass before his calloused fingers fiddled with battered folds. “Perhaps you liked being defiled a bit too much,” his master sighed, feigning dismay as he assessed the damage. The air around his fingers whistled as he struck Katsuki’s abused hole. “What a slutty pussy.” Slipping two fingers in, “I’ll find a new kitty if you stay this loose, I can barely feel you.” It had Katsuki clenching like a vice grip.
“Master, no!” Katsuki cried, the tears Shindo chased after were so easily cascading down his cheeks. “I’ll tighten up!” He babbled.
“Then use your words. I don’t like guessing.” Aizawa scolded, instantly receiving a much clearer answer.
“I need you to cum inside! I feel empty without it!” Katsuki hiccuped.
“Good boy.” Shouta praised, leaving a chaste kiss on the kitten’s lips before pulling away. He maneuvered the kitty with minimal effort, Katsuki’s body moving as if magnetized to Shouta. He pulled the hybrid atop him once he settled down onto the exhibition table.
If anyone were to walk in right now they wouldn’t have believed that the hybrid had been used like a toy by everyone occupying the room.
“You’re not too tired, kitten?” Shouta murmured against the side of Katsuki’s head, his two day stubble scratching Katsuki’s smooth shoulder. The hybrid whined, displeased with the idea that he wouldn’t be getting his master’s cum. “It’s okay, you’ll get what you need,” Shouta reassured. “Why don’t you put it in? Make us both cum.” he encouraged, engulfing Katsuki’s hips with large hands to start the motion.
The kitten keened happily, wiggling his hips as his cunt searched for his master’s cock. The searing length producing a lewd crackle of liquids as it ran through slick folds. Katsuki chewed on his bottom lip to stop himself from whining. He’d be good and do as his master requested, ignoring the ache in his body and the need for Shouta to just use him like a sleeve.
A pleased “Mmrrrmmm,” rattled against Katsuki’s throat, pleasure and pride filling his chest when he felt the first pop of Shouta’s raw cock into his needy hole. It had Katsuki melting like all he knew was his master.
Though his body twitched in overstimulation, his obedience won out. His hips moved following their deep rooted instincts to every extent of what it meant to be filled. It started with a slow roll of the hybrid’s hips, a weak grind that reminded Katsuki’s clit of their sweet connection. All the other stimulation paled in comparison to what he was feeling then, his master’s cock rubbing in all the right places. Almost as if Katsuki’s walls had been molded to only contain Shouta.
“You were made just for my cock weren’t you, darling?” Shouta commended. Katsuki mewled, craning his chin up to the ceiling, his master’s words driving him to bounce a little faster with one goal in mind.
“You really needed this.” Shouta continued, his grip on Katsuki’s hips becoming bruising, gracing his kitten with small mercies as he sat up, his thick length kissing the hybrid’s cervix. A whine tugged at Katsuki’s throat, Aizawa’s smirk going completely unnoticed to him as the teacher eyed his class. They all sat in awe as they watched Aizawa pick Katsuki apart without much effort.
When Katsuki’s whines became more desperate, Shouta grunted into his ear. “Say the magic words, Kitten.” His hips snapped stronger, but not a beat faster.
With what little control over his tongue he had left, Katsuki gasped a clear, “Breed me, please.”
White heat flooded Katsuki’s body as he felt the scorching spurts of Shouta’s cum against his sore walls. He missed the chorus of moans as he pissed himself. His cunt too stupid to keep anything in, his blond fur wet and matted with his mess. With what little brain function he had left he raised his hips, watching with heart-shaped irises as he saw a mixture of their messes dripping down Shouta’s flagging cock, feeling the bulk of it spilling from his fluttering hole.
Shouta reached to pull Katsuki’s cheeks apart to show everyone the damage between his legs, rasping to his students, “This is the result of proper obedience training. I hope you’ve taken notes to become the master your kitten needs.”
