Work Text:
Koji Koda had always been a shy boy. He always felt more comfortable around animals than he did humans. He understood them better, part of his quirk, Anivoice. He often wished people were more like animals.
But one day as he came out into the common room, he nearly tripped in surprise. There stood Uraraka, but the curvy girl had a drastically different profile than usual. A bushy squirrel tail protruded from the back of her hips and a pair of matching squirrel ears peaked out of her light brown hair.
Koda was speechless, not that you could tell. He’s pretty quiet on a normal day. But his face was flushed pink at the sight of her.
Uraraka turned, her large tail swaying as she moved. “Morning Koda, you feeling alright?” Her concern was genuine and seemingly clueless.
“Uh.....just.... ah.” Koda managed to sputter out.
A firm hand patted him on the back. Kirishima had come up from behind. “It’s your jogging top, Ochaco. You look good.”
Koda had hardly noticed the sleeveless top she was wearing, but he nodded in agreement. He had been wondering if she knew about her new animal features. But, now both she and Kirishima were acting as though she’d had them all along. He was mustering the courage to question the matter further when he saw Kirishima’s back. From the front, the muscular boy looked the same as before. But as he passed by, Koda was give a full view of the shark fin poking out of his spine just below his shoulder blades and the thick shark tail at his hips.
Still Kirishima and Uraraka seemed to not notice anything strange about their animal appendages. While the casually conversed, Koda slipped back to his room to put on his uniform and finish getting ready. Trying to convince himself it was a prank or a hallucination.
_____________________________________________________
Those notions were dashed as he walk to class. Everyone he saw had animal features. Namely ears and tails, but some had horns or wings depending on what animal they seemed to be mixed with.
He entered Class 3-A to see his classmates hadn’t been spared of this. Sato had the floppy ears and springy tail of a black pig. Yaoyorozu had small light brown ears and a tiny furry tail, she’s a Doe (a deer, a female deer). Kaminari had the large ears and tail of a mouse. Even their teacher, Aizawa, had the ears and tail of a black and grey long haired cat. No one seemed to question the emergence of these changes or question why Koda was the only one without animal traits.
Koda took his seat towards the back of the class and tried to calm down. But that was like stopping a river with just your hands. His heart thumped wildly with excitement and trepidation. This is...... this is Koda’s........ Paradise.
He’d always had trouble reading people’s emotions. It’s a big part of why he always feels so nervous around them. But now every twitch of their ears, every flick of their tails, it was like their body language was finally translated it a language he was actually fluent in.
Secondly, he had to admit he always found people with animal quirks more attractive. Male or female didn’t matter to him, but those furry tails drove him wild. Before his interest was limited to Tokoyami, Asui, and on some days Ojiro. But now, its the whole class. Scanning the room, all of his classmates looked more attractive than before.
“Koda, are feeling ok?” Midoriya’s voice drew Koda’s attention. He turned to see the freckled boy’s worried gaze. “Your face is kind of red, do you need to go to the nurse?”
Koda had been blushing as his mind was processing how to feel about the recent changes. But Izuku‘s cute face was leaning in toward him. A moment later, he leaned back again and that’s when Koda noticed the long rabbit ears matching his dark green hair.
Izuku turned to the front, giving Koda a glimpse of his small rabbit tail peaking out of the back of his school uniform. “Aizawa-sensei, Koda looks feverish. Should I take him to the nurse?”
Aizawa’s cat ears twitched in annoyance. “Whatever, just stop interrupting class.”
Izuku’s ears perked up. He took Koda’s hand and drag him out to the hallway. The shy boy allowed himself to be lead, because his eyes were locked onto each slight wiggle of Izuku’s cottontail. Izuku was worried, but also excited about something. (was his butt always that cute?)
They were half way to the nurse’s office when Koda finally looked up. His face flushed red again. If he went to the nurse’s office, Recovery Girl would instantly know he wasn’t sick, he’s just horny. He had an erection since he got into the classroom.
Koda gulped. He had to try something before this went any further. “Mi.....Midoriya, stop.”
The bunny boy froze. Not out of fear, but more like someone had hit pause. What no one knew was that Koda’s quirk didn’t just let him talk to animals, but command them as well. He had previously tested this with Tokoyami and sure enough, he can manipulate those with animal quirks too.
Seeing Izuku obey, Koda was emboldened further. “We’re not going to the nurse’s office.”
Izuku simple turned to him, his emerald eyes showing curiosity. “Then where are we going?”
Koda smiled. This is just like it was with Tokoyami. Rather than his commands being full mind control, they were more like subliminal messages. Once heard, the animal’s thoughts seemed to shift to allow this new point of view. As such, Izuku has just accepted Koda’s declarations without a second thought.
Glancing around Koda whispered, “Follow Me”. He quickly went down another hallway. He didn’t need to turn around. He could hear Izuku’s footsteps just behind him. He quickly found an empty classroom and ducked inside. Turning back to Izuku, he found the greenette watching attentively. His rabbit ears twitching slightly with anticipation.
“Okay Midoriya, I’m not blushing cause I’m sick. I’m horny and I’d like you to help.” Koda started to unzip his pants and his erection sprang out.
Izuku blushed slightly, but didn’t recoil or express any shock. His posture remained open and compliant. “Ok..... I’m happy to help.”
“get on your knees, Midoriya. Start by using your mouth.”
He knelt obediently. Gently holding Koda’s cock at the base as he began lick up and down the shaft. Diligently lathering the manhood in front of him. Koda covered his mouth to prevent audibly moaning. But as Izuku’s soft lips and agile tongue danced across the throbbing flesh, Koda choked on another command. Izuku paused his licking to let Koda talk. His rabbit ear twitching slightly as he listens intently.
Koda took a deep breath to center himself. He ran his hand through Izuku’s hair and rabbit boy’s ears folded back. Koda’s heart skipped a beat as he understood this gesture meant well.
Submission
Izuku was nuzzling up into his hand. Almost accepting Koda’s some sort of ownership of him.
“In...... In your mouth.” Koda managed to stutter out.
Izuku simple nodded, closing his eyes and leaned in. Taking the tip past his lips and begins bobbing his head. Whenever Koda applied some light pressure on his head, he bobbed lower. When he gripped Izuku’s head, he stopped moving altogether. Allowing him to begin thrusting into his waiting mouth. His throat constricting and relaxing in time with each thrust.
This might very well be Izuku’s first blowjob but he never gagged once. Perhaps becoming a rabbit boy made his throat more pliable. Regardless, Koda is near ready to burst. Each time he sheathed in the warmth and tightness, he felt Izuku lean in.
Koda’s breathing grew ragged as the pleasure built to an unbearable peak. With a final deep thrust, he hilted his manhood against the rabbit boy’s lips. Izuku’s nose pressed against Koda’s pelvis as the shy boy held his head in place. He throat constricted rhythmically and Koda’s throbbing shaft as to began unload spurt after spurt into his gullet. But the rabbit boy only closed his eyes and leaned in, as the warmth pooled in his gut.
As Koda’s climax started to wind down, he was able to catch his breath. And yet his softening cock stayed in a warm comfortable. He looked down to see Izuku still dutifully holding the softening length in his mouth. His emerald eyes looking up expectingly. He is waiting for permission.
Koda pet Izuku’s head. “Good boy, Midoriya. We’re done for now.”
Izuku shifted back, letting the member slip from his lips with a wet pop. He licked his lips and swallowed. His voice coming raspy. “I’m glad i could help.”
The two boys cleaned up and headed back to class. Izuku seemed calm and somewhat oblivious to the gravity of what they’d just done. However, the furious wiggling of his cottontail showed he enjoyed it.
_______________________________________________________________
The next day, Koda’s curiosity was burning. Despite his shyness, Izuku’s obedience the other day had emboldened his desires. In the boy’s locker room after gym class, he gazed into the showers. The sound of running water and casual conversations echoing off the tiles. His classmates were all showering their naked bodies and animal features on display without a hint of shame. A soft blush reaching Koda’s cheeks as he imagined playing with each of them. He clapped his hands on his cheeks to focus himself. He should start with one.
“None..... None of you will mind if I fuck one of you.”
The boys stopped their conversations for a moment, before resuming. The influence of Anivoice keeping them from questioning his declaration. Koda walked through observing their bodies, but honestly he’d already picked his choice.
In the corner, Iida was facing the wall as he scrubbed off his muscular body. The class president was one of the tallest and most bulky guys in class, but he was a little too strict to date. Making him an untouchable forbidden fruit. But now, Koda walked up right behind him and Iida didn’t even flinch. He could see the water washing down Iida’s back and shoulder, even over his firm rear and down his thick thighs. His hard work and workouts were only extenuated by his new horse ears and tail.
Koda came up next to Iida and tentatively put his hand on the horse boy’s thigh. Iida glanced back to meet his gaze, but quickly averted to hide his blush. But this only told Koda to go further. His hand slide around to the sensitive skin of the inner thigh and his fingers brushed against Iida’s balls, yet still the class president didn’t protest. His hand retreated back and moved to the horse boy’s buttocks.
“Iida,........ bend forward”
Iida stiffened but bent at the hip. Bracing his hands against the tiled wall of the shower. The new position presenting his toned buttocks at a more convenient angle. His horse ears flicked with anticipation. Like despite his usual trepidation toward the intimate, he is somewhat excited for this.
Koda gently trailed two fingers through the cleft of the firm globes before him. When they found Iida’s tight rim, he started to work them in. To his surprise, the horse boy’s inner walls welcomed the invading digits easily. As he scissored his fingers, the velvety walls had surprising give to them. Koda wondered if Iida’s hole had adapted like Midoriya’s throat had. After all, animals didn’t use lube. Maybe their holes are just more forgiving. Sensing he didn’t need to prep Iida further, Koda lined up his cock and began to gently thrust into the tight warm heat.
Each push was met with a flutter and clench of Iida’s insides. Soft moans slipping out as Iida began to rock forward with each thrust. His horse tail flicking with an unspoken desire for more. Honestly the flicking was getting on Koda’s nerves. Without even thinking, he reached forward and gripped the equine appendage around the base with one hand. Instantly, the class president went rigid. Koda flinched thinking he’s hurt him, but the next second Iida arched his back more. Pushing his hips high and back against Koda’s crotch.
A knowing smile graced Koda’s face. His free hand coming to hold Iida’s hips. As he began thrusting a little more forcefully, the horse boy was pushing back to meet each thrust, driving Koda’s cock deeper. Clearly a little manhandling played to Iida’s tastes, even if he’d been reluctant to explore them till now.
“hhhngh..... Iida.....”
Koda was near breathless. He’s breeding a stallion and he wasn’t going to last much long. Iida’s clenching hole threatening to milk his load straight out of him. With a strong yank, he pulled the class president’s rear flush against his own hips. His climax hitting and emptying his balls inside. A strangled moan ripping from Iida’s throat as the torrent of hot seed filled his passages. His own load shooting down onto the shower floor. The constant drizzle of the shower already working to flush the evidence down the drain.
As his release winded down, Koda loosened his grip on Iida’s lower half. The Horse boy immediately buckled to his knees like his legs had turned to jelly post orgasm. His muscles twitching in the aftermath of being so thoroughly bred.
Koda ran his fingers through Iida’s wet hair. Despite his fatigue, he pushed his head up into the petting. As if the gentle hand was a reward for being a loyal pet.
“Good Boy.”
___________________________________________________________
The next day, Koda was in the dorm’s common area still reminiscing his recent experiences. Deku’s tight throat, Iida’s firm ass, the way he can control everyone. It truly was like a dream.
“Da fuck are you so happy about, Rock Face?! You plow four eyes once and you turn into a perv like Grape Nuts?”
Koda was so engrossed in his reminiscing he barely even noticed there was anyone else there. He looked up to see Bakugo, the typically aggressive and rude boy was glaring down at him. Koda’s usual shyness coming back, Bakugo’s harsh tone made him want to sink into the couch and disappear. But when he actually looked up at the aggressive blonde, he was startled.
Bakugo has his usual scowl and glare, but atop his rough hair sits a pair of dog ears. A dog tail wagging behind his back. But mostly he’s sending mixed signals. His face shows anger, his ears twitch with annoyance, and his tail wags with....... anticipation?
“Bakugo...... do you........ want something?”
Bakugo’s dog ears folded down with anger, but his cheeks blushed. “I don’t need anything from you, damn nerd!!” He turned and started to storm away.
“Stay”
Koda wasn’t sure what surprised him more. The fact that the word left his lips or that Bakugo actually froze in place. His fists clenched at his sides, yet his wouldn’t take another step. His tail is wagging faster now. Koda had a theory.
“Come”
The word had barely sounded before Bakugo’s back straightened. He slowly turned on the spot, coming to face Koda again. Each step back to Koda’s side seemed to drag on, yet he kept his eyes on the floor the whole time, like his pride couldn’t let him meet Koda’s gaze.
His tail is wagging even more. Perhaps becoming a dog boy made him eager for commands.
Koda stands up from the couch and pets Bakugo’s head. “Good boy.”
The dog boy froze in shock, even his tail. Koda just smiled and went back to his dorm to get ready for class. Which is why he didn’t notice the mortified look on Bakugo’s face.
Koda figured that despite his aggressive behavior, Bakugo has always been looking for some gratification. He tries really hard in training. He has 3rd highest grades, behind Iida and Momo’s intellectual war. He does listen to the teachers and follows their instructions. Koda could almost imagine him as a dog before he got his ears and tail.
His theory almost seem to prove itself, as Bakugo seemed oddly quiet throughout class. During lunch, PE, and after classes ended, the dog boy followed a few feet behind Koda. If he was wearing a leash and collar, Koda could almost imagine he was taking him for a walk.
This trend continued till they were headed back to Koda’s dorm for the night. The shy boy opened his door, but looked back. “Did..... did you want to come inside?”
Bakugo wouldn’t make eye contact and was blushing slightly.
Koda held the door open. “Come in if you want.”
The dog boy came in. He looked around the dorm room, but didn’t seem that interested. His tail was twitching for anticipation again.
Koda just sighed. Bakugo was waiting for something, but he couldn’t put his finger on it. He’d been doing it since this morning....... when he called Koda a pervert...... for having sex with Iida........
It finally clicked and Koda nearly facepalmed. Of course Bakugo was expecting sex, he and all the other boys had a front row seat for him fucking Iida to a limp mess. He might have even guessed what Koda had done with Midoriya.
“Bakugo, get ready and on the bed.”
Koda didn’t look around to see if the order was being followed, but he could hear the subtle rustle of fabric. He’d been purposely vague in the command to see what Bakugo would do. He got his answer as he turned to find Bakugo naked, laying on the bed nonchalantly despite his legs being spread wide and his erection front and center. His ears folded back with embarrassment, but his tail wagging with barely contain arousal.
Koda chuckled slightly as he removed his t-shirt.
“Damn it!! What are you laughing at!?” Bakugo snapped.
“No..... Nothing, I promise” Koda blushed. He unzipped his pants and pushed them down with his underwear, his rapidly hardening cock spring forth. He felt telling Bakugo he laughed at how cute the dog boy was being would only make him more embarrassed.
He climbed onto the bed. Climbing on all fours till his bulkier frame loomed over the thinner blonde. He slowly insert into the dog boy’s tight hole. The velvety walls of his clutching rectum accommodating him like Iida’s had.
He started slow. Gently easing in, as Bakugo was tighter than the class president. The aggressive blonde winced slightly, though from pain or pleasure it’s hard to tell. He seemed to get over it quickly, soon he started to look sort of bored.
Bakugo’s ears flicked with annoyance. His voice dripping with sarcasm. “This feels crazy. Woooooow.”
Koda stopped altogether. Bratty Bakugo isn’t his favorite.
The dog boy glared back with equal parts frustration and panic. “Hey, are you gonna...... you know?”
“No.” Koda can be bratty too. “I’m not sure you want it.”
Bakugo’s face turned bright red with anger. “Goddammit! Will you just get on with...” He was cut of as Koda’s hand gagged him and pushed him down against the pillow.
“Stop.” His voice came sterner than most had heard him before. “We’re not doing this. And I’m not moving if you can’t be honest with me when we’re alone.”
After that, he removed his hand, yet Bakugo remained in a somewhat stunned silence. Koda just sighed. Midoriya and Iida both had very obvious body language tell him they wanted and enjoyed it. But Bakugo still seemed to be giving him mixed signals.
Bakugo just lay there, his hands clenching and unclenching, as he grabbed the sheets beneath him. Frustration, arousal, anger, neediness, panic all warred across his face. He was wrestling with the question frantically. His breathing growing heavier and his face a deeper red. Finally he threw his arms around Koda’s neck, holding him close enough their bare chests were touching. His face pressed to the buffer boy’s collarbone.
“Dammit, I....... I want you to fuck me rough.”
Koda began to thrusting deeper, more forcefully. At first, Bakugo flinched and gripped Koda tighter. But after a few seconds, his limbs seemed to go limp and he slumped back down onto the bed. His face flushed and needy, like his walls had finally been knocked down and the flood was here.
“Fuck.... fuck.... i want.......damn it....... i want to be your pet. I want you to pet me. I want you to take me on walks. I...... I want....” Bakugo stuttered.
Koda chuckled slightly, “Do you want to be a good boy for me?”
Bakugo’s eyes snapped open, “Damn it, don’t call me that!! When you did it earlier I jizzed in my pants!!”
“Awww. But you’re my good boy.” Koda kissed his cheek and punctuated his words with a deep thrust.
“Stop....... I'm not....” The dog boy’s voice had no conviction behind it. His tail wagging furiously between Koda’s thighs, tickling his balls.
“You are, Bakugo. You’re a good boy. A very good boy.”
Koda’s thrusts and praise was driving Bakugo crazy. The heat in his gut and flushing face made him dizzy and horny all at once and quickly pushing him to the brink. His back arching off the bed as his climax ripped through him. His untouched manhood shooting his load onto his and Koda’s stomachs.
As his high came down, the dog boy slumped onto the bed boneless. Koda stopped his thrusts and was about to pull out.
“Hey.” Bakugo’s voice was tired but still held some sharpness. “Finish.”
“Huh?” Koda blinked confused.
Bakugo’s dog ears twitched embarrassed. “You didn’t cum....... go ahead and finish.”
Koda was taken aback, but smiled and nodded. “Good Boy”
Bakugo met Koda’s gaze. A resolute look in his eyes. “If I'm a...... a good boy. Then I want something.......”
___________________________________________
The next day, Class 3-A was abuzz as many of them crowded around Bakugo’s desk.
“It looks sick, man. Where’d you get it?”
“It really suits you.”
“Makes you look manly, dude”
All eyes were pinned to the leather collar around Bakugo’s neck. He was sitting up and tilting his head back. Trying to show it off like a badge of honor, while still seeming somewhat nonchalant.
Ashido sighed, her lizard tail swishing slightly, “Maybe I’ll go get one myself later and..”
She was cut off as Bakugo slammed his fist on the desk. “No, you don’t.” All eyes turned to him surprised by his oddly passionate response. But Bakugo continued.
“You can’t just buy one. You extras have to earn this and have it given to you.”
It took the class a moment to get over the shock. They begin to go toward their desks, breaking into conversations on what Bakugo had done to earn his collar and who had given it to him.
Koda chuckled. He’d been watching the whole thing from his seat. His timid reputation still keeping him under the radar.
“Hey, Koda.”
He was dragged from his thoughts with a start. He glanced over to see Midoriya and Iida standing by his desk. They both were blushing slightly, their ears and tails twitching with expectation. Koda smiled fondly. Of course, if his dog had earned himself a collar, surely his rabbit and horse had too.
When the two boys came the next day sporting collars just like Bakugo’s, the class erupted in whispers. But seeing Iida collared, the boys quickly figured out what was needed to earn a collar and they informed their female classmates.
_________________________________________________________
Aizawa was almost back on the UA campus grounds after a run to his favorite local coffee shop, when his cat ears twitched at the sound of approaching steps.
“Eraserhead! Eraserhead, can I get a quick interview?”
He turned to see a report with the ears and tail of a fox came up. The small light on his chest told him the man had a body cam glowing on his suit jacket.
Aizawa sighed, “Make it quick.”
The reporter perked up. “Is it true the school has added leather collars to the dress code?”
“No.” Aizawa was blunt and unimpressed.
The reporter chuckled, “Can you elaborate?”
Aizawa sighed, “The collar’s aren’t part of the official dress code. They’re a fashion trend among the students.”
The reporter cocked his head to the side, “A fashion trend? A trend that’s reportedly done by more than 80% of the 3rd year classes and even some of the teachers?”
Aizawa’s cat tail twitched with annoyance, “Yeah”
The reporter’s enthusiasm took a hit. He spoke in a slightly more professional tone. “And what does the school plan to do about the collars?”
“Nothing,” Aizawa shrugged. He continued when the reporter raised a quizzical brow. “The collars haven’t proven to be a detriment to students’ performance, grades, or focus. So the school sees no reason to interfere.”
The reporter’s fox ears drooped completely. “So, officially, the school doesn’t condone or condemn this trend?”
Aizawa nodded.
The report nodded back and switched off his body cam. This clearly isn’t the juicy story he thought it’d be. “Well thank you for your time.” He turned to leave, but stopped. His ears perked up as a new thought came to him. He turned back to Aizawa with a knowing smirk.
“Eraserhead, one last question. Off the record.”
Aizawa raised an eyebrow.
The reporter leaned in. “Are you wearing a collar?”
Aizawa rolled his eyes and left. The reporter left too, still smirking.
______________________________
Aizawa couldn’t understand why people questioned the collars so much. It was obvious they didn’t effect the students learning. And its not like the collared students where barred from studying or participating. Why would people think they’d change anything about the classroom.
He walked to Classroom 3-A. He didn’t even look at the class as he entered. The talking died down and the shuffling of desks stopped as they took their seats.
He set his coffee down on the desk at front of the classroom. He took off his scarf and set it on the desk too. His jacket and shirt quickly followed. He turned to the waiting class, his bare chest and the collar around his neck on full display. Despite this not a single student flinched. This was a daily routine.
Aizawa’s gaze scanned the class of patient collared students, till he focused on the one student not collared. Koda smiled and gave him a simple nod. So with his owner’s permission, Aizawa began the day’s lesson.
