The school was empty, everyone having already left for the day- everyone except Bakugou Katsuki. His heavy footsteps echoed through the vacant hall, the sound bouncing off the walls to ring quietly in his ears.

His hands were clenched at his sides, sweaty and tired from his extended training. His brow was furrowed from his inability to master the technique he’d been working on for the past two days. He could still hear Aizawa’s monotone voice telling him to take a break for the day. His frustration levels were at an all time high.

Training was how he usually dealt with his anger, the heat from his explosions and the adrenaline coursing through his veins allowed him to focus his energy on something productive. That, and it was nice to vent out his frustrations and blow shit up.

Throughout all his years, training had never been the cause of his ire. He’d never had any difficult in controlling his quirk, never felt the tiredness aching in his palms as heavily as he did tonight. It was foreign to him, and it left him feeling a little lost.

Things had been different for him ever since he started at UA. Everything was more difficult than he’d ever experienced. UA demanded the best from him. It required all of his time, effort and attention. It forced him to look at the weakness that had snuck inside him and conquer it, all within a short amount of time. It was enough to give someone whiplash, if they weren’t paying enough attention.

But that- that he could handle. He conquered every battle, every challenge, and every test that was thrown at him with practiced ease. It hadn’t taken him long to adjust to the demands of UA’s famed hero course.

It was green hair and freckled cheeks, soft laughs and determined eyes that set him continuously on edge. Despite him not being in the hero course, instead being accepted for his potential as a support course star student, he seemed to be everywhere Bakugou looked. Always helping everyone else out with a smile, showing off his new creations with a confidence that made Bakugou’s emotions get mixed up inside him.

He sighed, feet stilling as he found himself standing in the support course hallway. It was dark and empty, but Bakugou could still envision Deku running through the hall, notebooks in hand, rattling off ideas for new support items with Hatsume Mei.

The issue was that Deku was great at what he did. Everyone wanted the freckled boy to improve their costume or make them something to improve their combat ability. His past habits of jotting down hero analysis in his notebooks came in handy when studying a future hero’s movements and quirk. It let him see openings in their defenses and improvements they can make. He took his love and enthusiasm for heroes and channeled that into making some of the best support items Bakugou’s ever seen.

All over again, Bakugou felt like he was lagging behind his childhood friend. He trained and he conquered and he clawed his way to the top and yet he was still out of reach. His hand was always just far enough away that he grasped at empty air rather than a sturdy back.

He was nearly ready to march back to the gym and spend a few more hours training now that his motivation outweighed his frustration when he heard the distinct sound of mechanical whirring. He paused, inching towards the large door of the support course workshop, the soft yellow glow of the light from the classroom beckoning him closer. 

He could hear the soft buzzing of the machine more clearly than before. It was a soft hum, similar to the sound of his electric toothbrush back in the dorms. The whir of whatever was moving behind the door stuttered slightly, like something got in its path for only a moment.

Bakugou was about ready to shrug it off as some nerd working on a project when the rest of the support class wasn’t around, but then he heard a soft groan float through the air.

His entire body stilled, body becoming impossibly hotter, his eyes widening. He shifted back to the door as quietly as he could and leaned in, pressing his ear against the wood. He held his breath so that nothing was obscuring the sounds that were spilling from the inside of the workshop.

He could still hear the hum of the mechanical parts from inside the classroom, but it was now accompanied by a distinct, yet quiet, wet sound. It was steady, squelching deliciously with the rhythym of the buzzing. Soft and breathless moans rang through the heavy wood door more gradually, the whirring of the machine inside slowly buzzing faster.

Bakugou felt a wave of heat wash through him, his body far hotter than it had been when he’d finished training.

This was a different type of heat. Internal, stirring at his belly, his cock standing at half mast in his trousers, lips caught between teeth.

He felt himself twitch as a loud, keening moan rang through the hall. It was desperate and needy and downright sinful and left Bakugou somewhat breathless himself. It was no secret what was going down behind those doors now. The mechanical hum was louder now, faster, beating at a steady rhythm that was no doubt drawing the delicious moans out of whoever was in the room.

He felt the pull of curiosity wash over him, hands itching to reach out and slam the door open to see the dirty slut’s face. He wondered if they’d even notice him or if they were too blissed out to care. He questioned if they’d turn a deep red and try to cover themselves, and he’d have to pry their hands away and force them to continue, or if they’d only get more turned on by having an audience.

He was suddenly desperate to find out, but he held onto his self-control- if only by a thread- not wanting the show to end too soon if he spooked them enough to make them stop. He wanted to burst in when they were hot and desperate and too needy to finish to stop at an intrusion. He wanted them to beg him to let them continue, to let them fall to their dirty pleasure while he watched.

Instead, he sunk to his knees, pulling himself out of his boxers as the moans coaxed his hand to wrap around sensitive flesh. He started himself off at a slow rhythm, grip loose- just enough to give him the friction he craved.

A predatory smirk formed on his face as his mind conjured up dirty images of what may be going on behind these solid wood doors. The person splayed across a desk, hips rocking back and forth in time with whatever dirty machine they created. On the ground, legs up in the air, a hand wrapped around themselves, desperate to reach their limit.

His own hand was taking on a faster speed, grip tightening and hands twisting in just the way he liked. A drop of pre-cum rolled down his length, allowing his hand to glide more smoothly across his hot skin. He sucked in a quiet breath, thumb playing at the head as a loud moan rang through the hallway.

The person inside the workshop was certainly enjoying themselves. He could hear the desperation in their voice, the tone high and keening in such a perfect way Bakugou was sure they could make it as a porn star if the whole support business didn’t work out for them. It made him fantasize about plump, pink lips, opened wide and wrapped around his dick like they were made to do just that.

He groaned at his mental image, head lolling back to rest against the heavy wooden door. He felt it shift behind him, sliding open, and he would have fallen backwards if his reflexes weren’t so fast.

He realized, then, that the door hadn’t been properly latched in the person’s hurry to get into the room. The soft glow of the lights from inside the workshop spilled into the dark hallway, a thin sliver opened enough to allow him a peek inside if he chose.

He sucked in a breath; his hand still wrapped around himself as he stared at the light pouring through the crack. He shifted as quietly as he could away from the door, a buzz of anticipation washing over him.

The mechanical sound was clear now, no longer muffled by the heavy wood. He could hear the slick sounds and breathless moans coming from inside, enticing him. He gave himself a slow pump as he neared the door, hands halting at the base and gripping, prepared to stop himself from coming undone at the sight that was waiting for him.

He leaned in, red eyes squinting as they adjusted to the light. He could make out the familiar work stations lined in neat rows, metal stools tucked in and awaiting the students return the next day. At the front of the room was the sensei’s desk, lined with various tools and equipment, ready to be used. And there, bent over a work desk, hands clawing desperately at the wood and head snapped back in pure ecstasy as a machine fucked into him, was the one person Bakugou never expected to see behind these doors.

His green hair was a curly, knotted mess, slickened with sweat and sticking on his forehead. His pale, freckled body was flushed a pretty red. His lean legs were shaking with the effort it took to keep himself upright, his hand moving desperately between his legs. And there, perched behind him on a metal stool was a fuck machine, no doubt lovingly crafted by the same man who was being fucked by it right in this moment.

It looked fairly simple from where Bakugou was standing, a jumble of spare parts that no one would notice went missing. Two metal poles to keep it standing upright, a circular gear situated at the back. Attached to that was another pole that would allow the dildo to be thrusted back and forth with each rotation. It was accompanied with a motor and a hand switch that was lying on the desk next to trembling hands that no doubt controlled the speed.

His eyes hungrily watched the scene, licking his lips at the cries falling from Deku’s mouth. He zeroed in on the sight of the large, black dildo sliding in and out of Deku’s tight hole and the plump cheeks that looked like they were begging to be grabbed, slapped and bit.

His hand gripped his shaft and gave a harsh tug, twisting as it reached the head.

Suddenly, all his fantasies came rushing back to him, only with Deku filled in as the mystery person. He imagined himself waiting until he was just about to let himself fall to his pleasure before slamming through the door. The nerd would no doubt jump at his intrusion, and he’d try to run from him in shame. But he’d chase him down and drag him back to his machine and force him to take it until he cried.

It was enough to ignite a fire in him, the sudden burning need to see Deku’s teary eyed face almost too much for Bakugou. He hissed out a breath as he gave himself a few more good, long strokes before he tucked himself back into his boxers.

He didn’t want to give Deku the pleasure of knowing he was jacking it while watching him fuck his dirty little machine.

He ran a shaky hand through his blonde hair, watching Deku with intense eyes, waiting for the perfect moment to strike.

The other man was bouncing back onto his machine, ass jiggling with each movement. His moans were becoming more and more broken, the hand moving between his legs moving faster, legs twitching with effort. He desperately reached his left hand out, searching for the switch, crying out as he turned the speed up. The machine was fucking him fast, hard and deep, vibrating enough to be rattling the metal chair it was perched on.

His hips were stuttering with the intensity of the thrusts, his body tensing as he was no doubt nearing the edge. Bakugou was fairly impressed by his stamina which only made him wonder how often he used this little machine he created.

A pink tongue came out from his mouth to lick at his lips as he decided to slowly push the door open more, just enough for him to sneak through. He didn’t need to be quiet anymore, the loud hum from the machine and Deku’s cries were enough to drown out any noise he could have made.

As he neared the trembling boy, he decided he much preferred the view up close. He could see every swell and dip of Deku’s body, could watch as sweat dripped down his back and pooled on his lower back where his ass was perched so prettily.

He paused, only about an arm’s length away from Deku and simply watched for a moment, taking in the beautiful sight before him.

Deku was perfect. A perfect little slut that would be perfect for him to tame, hold down and fuck until he was a screaming, blubbering mess.

His hand twitched, readying itself to reach out when Deku let out a long, drawn out moan of his name- “K-Kacchan”.

Bakugou paused, hand hovering in the air above Deku’s hips. His face was plastered to the work table, pretty green eyes screwed shut in pleasure. There was no way he could have known he was here.

It meant that in his little nerd’s head, he was the fantasy. There was no doubt he was imaging the machine fucking into him was Bakugou’s own cock. He was screaming and crying and fucking himself after hours in their school to the thought of him.

It sent shivers down Bakugou’s spine.

He was suddenly struck with how right this all seemed for him. Deku was right there, in front of him, vulnerable and ready to break- right where he should be, as he should be. All those years of their childhood was preparing them for this moment when Deku would finally be destroyed by Bakugou’s hands and become his. All that was left to do was to reach out and take what always belonged to him.

With no hesitation he lifted his hands, reaching out towards his Deku. He passed over the plush, warm body even though his hands shook with the need to reach out and claim him. He instead brought it to the switch lying abandoned on the table.

He smirked as his finger lowered the dial, watching the machine slow to a painful pace, Deku crying out at the sudden lack of stimulation and in utter confusion. He let out a deep, sadistic chuckle as he watched Deku’s hips stutter back into the machine, searching out the stimulation that was ripped from him.

He saw the body tense at the sound, and watched with amusement as teary, blown out green eyes slowly turned towards him, face draining of color as their eyes met.

Time stilled for a moment, the two staring at each other- one in a merciless, sadistic way, the other in pure terror and embarrassment. And, much like Bakugou predicted, the green haired boy tried his best to run. But he cried out and fell to the floor in a heap as the dildo slipped out of him.

Bakugou laughed, deep and dark at the sight before him. Deku was trembling on the floor, a mess of bare skin and body fluids. He shook his head and crouched, a strong hand coming out to grip at the mess of green curls, harshly tugging them back to bring Deku’s face within inches of his own.

They shared a mingled breath before Bakugou grinned, and he watched Deku’s Adam’s apple bob with a heavy swallow. He’d be making good use of that throat soon.

He tugged at Deku’s hair once more, forcing a small groan out of the boy, teary eyes finding his again. He tilted his head, lips forming a smirk, showing off sharp canines as he asked, “where do you think you’re going, Deku?”

The deep rumble of his voice sent visible shivers down Deku’s spine. Bakugou let his eyes drink in the sight before him. Green irises devoured by black pupils, flush making dark freckles stand out more on his pretty face. Eyes worked down a lean chest that was dripping with sweat to thin, yet muscular legs that would look great wrapped around his waist. He licked his lips when he eyed Deku’s pretty pink head, glistening with drops of pre-cum, giving away just how needy the other boy was.

He felt a familiar rush flow through his veins, hot and heavy. There was something about looking at Deku, crushed and whimpering on the ground that fanned his sadistic side, that made him want to throw him down onto the floor and claim that tight hole for himself. To fuck him just hard enough that he’d be hooked on Bakugou’s cock, just to tear it away from him right before he came undone. He’d laugh and lick up the pretty tears that would track down plump cheeks and make Deku beg him like the cock slut he knew he could be.

He glanced out of the corner of his eye to where the fuck machine was still propped on the metal stool, thrusting into empty air. With each thrust it was beckoning Bakugou towards it, inviting him to use it to his advantage. With another look at the shaking mess on the ground, he smirked and knew that he didn’t want the show to end so soon. He wanted to have some fun torturing that sweet ass before he sank into it.

The hand that was still buried in green curls tightened and with little effort, he pulled Deku up off the ground. The other boy leaned heavily on him for support, his legs weak and shaking, his bare chest against Bakugou’s clothed one.

Bakugou marveled at how soft the pale skin was beneath his fingers, running a hand down a lean back, fingers scraping just enough that it ripped a slight moan from the other boy. He laughed, loving how sensitive he was before he flipped the boy around and threw him onto the table.

Deku landed with his chest against the work station, ass perfectly splayed out in front of Bakugou, legs far enough apart that he could see the tight ring of muscle twitching with need to be filled. He reached a hand out, swinging it down to make contact with a plush cheek, watching with fiery eyes as the flesh bounced on impact. It ripped a quiet moan from Deku’s lips and Bakugou decided that it was one of his new favorite sounds.

“It looks like this slutty ass of yours is begging to be filled again, Deku,” he drawled out, hands grabbing at his ass and pushing the cheeks apart to reveal the puckered hole. He ran a teasing finger between the cheeks, eliciting a needy whine from the other boy, his hips twitching into empty air. He reached behind him and pulled the stool with the machine closer to him. The stool screeched against the floor as he dragged it towards them, Deku turning his head to the side at the sound.

Pretty eyes widened when his hazy mind put together what Bakugou was planning. He tried to squirm out from Bakugou’s tight grip, but he was far too late. The machine was perfectly aligned with his hole, ass spread open by Bakugou’s hand and with the next thrust, the machine was nestled back inside Deku, a strangled moan spilling from his mouth.

Bakugou grinned at the sight. His hands were still gripping Deku’s ass, and he could feel the cheeks shake with each slow thrust of the machine. He watched with rapt interest as Deku’s hole swallowed the entire dildo with ease, ass tightening around it and sucking it in deeper, Deku’s hips stuttering backwards.

“Fuck,” Bakugou groaned. Deku was bouncing back on the machine on his own, all embarrassment from earlier faded and replaced by pleasure. His back was arched, letting the machine drive inside him deeper than it had been before, head thrown back and screams ripped from his throat as the machine fucked into him with a slow, steady rhythm. “look at your pretty ass taking that fucking dick so good. Fuck, Deku, you’re such a fucking slut.”

He half expected Deku to shy away from his compliments- to be the blushing, bumbling idiot that he usually was. But as soon as those sinful words slipped past his lips, green eyes were locked onto his own. The bastard cried out his name as their eyes met, cock twitching violently between his legs.

“K-Kacchan, please,” he whined, his voice wrecked from the screaming he’d been doing. Bakugou grunted, holding back a moan. He was used to the nerd calling for him with that sickly-sweet nickname from all those years ago, but not in that broken, needy tone. It only made him want to break him more; hear how pretty his voice would sound when it cracked with pleasure, when he was only able to scream his name. “please, faster. Please make it go faster.”

Bakugou paused a moment, brain foggy with lust. His hand was still gripped around the switch that controlled the pace of the machine; the dial set to as low as it could before being turned off. He smirked, realizing the sheer amount of control he had over Deku in this moment.

He tried to control his racing heart as he leaned in towards Deku, a dark chuckle escaping his lips as he watched a single tear fall from the corner of Deku’s eye. A hand reached out and wiped it away with a surprisingly gentle touch, but with sinister intentions.

“I can do that for you,” he drawled, pausing to watch Deku shift, squirming against the machine and the dildo inside him impatiently. He ran a finger down to Deku’s soft lips, pushing it against them until Deku opened his mouth and took it in, tongue wrapping around the digit. He smiled appreciatively, somewhat impressed by Deku’s intuition to know exactly what he wanted. He wondered if Deku was already broken enough to bend him to his will, or if he was just a natural slut, made to be ordered around.

He pulled his finger away from the warm mouth and brought his hand under his chin, raising his head to force him to look straight into his piercing red eyes.

“I’ll make you feel so fucking good, but you have to be a good little slut for me. You have to do what I tell you to, and you can’t open that slutty mouth of yours unless I tell you to. If you disobey me, I’ll fucking leave you here with no way to get off but your hand, do you understand?”

He watched as the lithe body shook with every word he said, the moans spilling from plush pink lips growing louder. He nodded his head, green curls spilling across his forehead as he chanted ‘yes’ under his breath and Bakugou knew he had him right where he wanted him, and he hadn’t even touched him.

He decided to have a little mercy on the boy, finger playing at the dial and shifting it up only one notch, watching as the machine whirred a bit louder, thrusting in and out of the other boy faster, but still at a slow pace. Deku threw his head back, mouth wide open, a mantra of ‘yes’ and ‘thank you’ falling from his lips.

Bakugou decided to let those words spoken without his prompting go, just this once, to let the boy enjoy himself. He’d have plenty of opportunities to discipline his nerd until he was a perfectly trained little whore, just for him.

He reached back and pulled out a chair for himself, slowly easing himself into it without taking his eyes off of his pretty little Deku bouncing back on his machine like a greedy bitch.

He felt his cock throb in his pants, weighing heavy against his stomach and he finally decided to let himself free. His hand reached down to pull away the zipper, leaving it undone as he pulled out his hard length and gave himself a soft stroke, sucking in a heated breath.

The sound got Deku’s attention. He lolled his head to the side, too blissed out and weak to raise it off the table. His eyes immediately fell onto the space between Bakugou’s spread legs, face flushing even deeper as he nearly cried at the sight.

“F-fuck, Kacchan,” he cried, his hand flying from its place on top of the table down to between his own legs, desperately gripping his own length to give it a hard stroke.

Inside, Bakugou was ecstatic that just the sight of his cock had Deku reacting that violently, but outside he was scowling, hand pulling away from his aching dick and reaching out to grip Deku’s wrist and pull it towards him.

“I don’t fucking remember telling you that you could touch yourself,” he seethed, jumping off his chair and slamming Deku’s hand back onto the table. He leaned in, making sure to purposefully grind his hard dick into Deku’s side, giving him a taste of how hot and hard he was. He grinned at the whine it drew from Deku’s throat. “and one more word out of that pretty mouth without my permission, you’ll be punished.”

Deku keened but nodded his head, teeth sinking deliciously into his lips to stifle anything else that wanted to slip out of them.

He turned his attention back onto providing a good show for Bakugou, hips rocking back to meet the machines thrusts with vigor. Bakugou leaned back into his chair, spreading his legs and relaxing back into his seat, slowly stroking himself while watching his pretty little Deku fuck himself.

He decided he wanted to see Deku come undone even more than he already was. With one hand still slowly stroking his shaft, the other moved the switches dial up. The machine whirred louder, starting to fuck into Deku at a respectable pace, the other boy screaming at the sudden increase in pace.

He smirked, enjoying the sweet reaction from his perfect little plaything and stroked himself faster. He grunted, “Fuck, you like that Deku? Course you do, you little whore. Being fucked by something you created just makes you feel so dirty doesn’t it?”

Deku only moaned louder at his questions, his ass greedily sucking in the dildo on the edge of his machine.

“God, look at you. You know just how to take that dick, don’t you Deku? How often do you fuck yourself with that machine, huh baby?”

Watery green eyes shifted to look at him, entire body bouncing with the force of the machine’s thrusts, the mechanical whirring loud enough to muddle the beautiful moans spilling from red lips.

“F-fuck, this…” he broke off into a needy, breathless moan as he angled himself to allow the dildo to slide into him deeper. Tears streaked down his pink cheeks, body shaking and back arching beautifully. “This is my f-first time using it.”

Bakugou stared for a moment, watching his little nerd take the dick sliding in and out of him with ease. Everything about the way he was positioned to take the machine, the way his body arched and moved perfectly and the breathless moans made Bakugou think that was a lie. There was no way his little Deku had never done this before.

“Bullshit,” he said, voice low and dangerous and he smirked at the small hitch in Deku’s breathing. His hand abandoned his leaking cock in favor of stalking over to where the boy was positioned on the table. He sucked his bottom lip in with his teeth, hand reaching out to roam the expanse of bare skin on display, coming down to grab a fist full of soft, plush cheeks.

“There is no way this fat ass hasn’t taken cock before. You probably come down here all the time, making dirty little machines to fuck you, don’t you? That’s why you wanted to get into UA’s support course so bad. You needed to, so that you could feed into your filthy fucking kinks.”

He punctuated his words with a few slaps to the other’s ass, watching as the cheeks jiggled and the skin turned a pretty pink. Deku moaned, a hand reaching back to spread his cheeks, eyes hooded and looking over his shoulder at the blonde- enticing him.

“Hah… I-I just needed to feel good, Kacchan,” he panted. Bakugou cursed under his breath, chest rattling with his heartbeat, body abuzz with dull tingles of pleasure at just hearing Deku’s wrecked voice. The view only made it better. “M-my hands weren’t, ah, they weren’t enough anymore.”

Bakugou moaned at that, mind flashing to images of Deku desperately thrusting fingers in and out of his cute little hole, moaning and rocking into his hand. He wondered how often his cute little slut was touching himself, if he screamed his name every time.

His body and mind cried with need to find out. A fire ignited inside him, and suddenly all he could think of was that the plush ass in front of him was made for his cock.

He leaned in, full of confidence, breath washing over Deku’s red tinted ears. He let silence fall over them, the only noise being the slick, wet sounds and whirring coming from the machine plunging into Deku’s ass. He could hear the other boys choked off noises, soft and quiet in the back of his throat. He knew that he wanted to hear them, to have Deku lose himself to pleasure so thoroughly that all his inhibitions flew out the window.

He licked a hot stripe up his ear, hands trailing up his sides to latch onto hardened nipples, twisting and tugging at them.

“Do you always think of me when you do this baby? Were you imaging it was my cock ramming that tight ass of yours?”

He laughed darkly as he watched Deku choke, body trembling and hazy mind trying to find words. Slow hands descended from pert nipples down a surprisingly solid abdomen, a light hand wrapping around hot and heavy flesh between the others legs.

Deku jolted, ass thrusting back to fill himself to the brim, cock twitching in Bakugou’s hand- and if the blonde hadn’t had the foresight to grip the base tight enough to stop the impending orgasm, their fun would have ended far too soon.

“Now, now Deku, you can’t cum until I tell you to,” he whispered into his ear, giving it a teasing bite. Deku gasped, hand coming down to grip at Bakugou’s wrist. His fingers were still tightly wound around the base of Deku’s cock, and he squeezed a silent warning for the other boy.

“Can you be a good boy for me, Deku? Do you want to be a good little cock slut for me?”

As he asked, his hand gave a few slow strokes to the other boy’s flesh, relishing in the tremors that wracked his body.

The other boy only nodded his answer, eyes screwed shut and voice betraying him, too weak and wrecked to emit sound.

It made him even more beautiful to Bakugou.

He smiled, a genuine smile. His pretty little Deku was going to be the perfect bitch to train and he was going to love every single second of it.

A soft hand reached out to lift the other boy’s face to his own, gently stroking his soft cheeks as he leaned in to give him their first kiss.

He could feel Deku sigh into his mouth, their breaths mingling together. Deku’s lips were wet with saliva and impossibly warm, and Bakugou immediately knew that he wanted to take everything he could get from the other boy.

His tongue swiped into that hot mouth, gently prodding and exploring. One hand was still wrapped around his cock, giving it gentle, slow strokes that were just enough to keep him breathless. The other was moving into the green curls, carding through them with a soft touch.

He wanted to savor the moment, because he was going to absolutely demolish the other soon.

He pulled back, a trail of saliva keeping them connected for a moment before it broke and landed on Deku’s chin. It made his skin sparkle in the light of the workshop, highlighting the prettiest mouth Bakugou’s ever seen and made his cock twitch in anticipation. Deku was still jolting forward with each slow thrust from his machine, eyes hazy and pupils blown in lust and- fuck, Bakugou needed to get his dick in him.

In one quick movement, Bakugou pulled his chair closer to them, sat with his legs spread, a cocky smile on his handsome face. Deku watched him with rapt interest as he slowly stroked himself, his other hand swinging to rest on the work station behind him.

“Be a good boy and use that sweet little mouth of yours to suck me off.”

Deku gulped and wasted no time in prying himself off the table, leaning over to where Bakugou was sitting. His movements caused the machine to thrust out of him, ripping a loud groan of protest at the loss of stimulation. He crumpled to the ground, falling just short of where Bakugou was seated.

Bakugou clicked his tongue in mild irritation at the interruption as Deku looked up at him with tear filled eyes.

“K-Kacchan, I-I’m sorry,” He whimpered. “I-I want to be good for you…”

He scooted himself to the other man’s legs, hands sliding up thighs as he rested his cheek on his knee, nuzzling into it. Shaky hands played just below his beltline, big beautiful eyes watching him like he was the most amazing thing in the world, ready to worship him- just as his sweet Deku should.

Bakugou sighed and turned the dial down until the machine slowed to a stop, the workshop now quiet without the sound of the mechanical gears grinding against each other. He ran a slow hand through Deku’s tangled curls, a soft sigh falling from the other’s lips.

“Fix yourself back up baby. I want to watch you fuck yourself on your dirty machine while you choke on my cock.”

Deku sucked in a heated breath and shifted, cock bouncing as he nodded. He stood on shaky legs, repositioning the stool that held his machine to line up with his hole once again. He cried out as he slowly sank back onto it, breath stuttering as he tried to readjust to being filled. Bakugou watched patiently, a slow hand stroking himself. He was pleased with how well Deku was obeying him so far.

Green eyes looked up at him, big and beautiful as he bent forward, face close enough to his cock that he could feel warm breath wash over it with each breath the other took. He gripped it, moving it to rub on Deku’s freckled cheek, leaving behind a glistening wet spot of his pre-cum.

He slowly turned the dial of the machine back on, the buzzing refilling the room as the dildo leisurely thrusted into the other.

Deku smiled and it sent Bakugou’s heart into overdrive as he turned his head and swallowed his cock down to the base in one easy go. He groaned out in pleasure, Deku’s hot tongue wrapping around his girth, head bobbing and throat constricting around him in a beautiful, perfect way.

A strong hand found its way to his hair, pulling Deku down further on his dick, twitching as he felt the velvety walls of his throat squeeze him as he choked.

“Fuck, fuck Deku,” he chanted, the other boys’ hands coming to grip his thighs as he bobbed his head back and forth, green eyes watching his every movement intensely. Bakugou was seeing stars, his entire body being set on fire at Deku’s ministrations.

It was perfect. The way he moved his head, the way his throat tightened around his dick, the wetness of his saliva mixing with his salty pre-cum, giving Deku ample lubrication to slide freely up and down.

The sight was even better. His pretty pink lips stretched wide to accommodate Bakugou’s massive length, cheeks flushed with the effort, tears gathering at the corner of his eyes. Bakugou knew that this sight would forever be emblazoned in his memory.

He looked past the pretty picture in front of him to where he could still see the machine fucking into Deku’s tight ass. A sinister smirk found way to his face, his hand gripping the switch, finger slowly turning the dial up and watching in delight as the machine whirred to life behind Deku. The black dildo was slipping in and out of view, each thrust harder and faster than the last, pushing Deku forward onto Bakugou’s cock even more.

The boy was moaning around his cock in pleasure at the sudden increase in pace, the sound sending pleasant vibrations down Bakugou’s dick, adding to the sensation. Bakugou almost lost himself there, the sounds and the sight almost being enough to push him off the edge, but he reeled himself back in, knowing there was more fun to come.

“Fuck,” Bakugou hissed out. Deku was still swallowing him like a champ, never once coming up for air for more than a second. He plunged himself back onto the machine, dick sliding deep into his ass before he jolted forward and swallowed Bakugou’s cock. “look at you, taking that dick and mine like a fucking pro,” he said, losing himself in the sensation, hips rocking forward into Deku’s inviting mouth. “I bet you could make some serious cash if you let people fuck you like the little whore you are.”

Deku cried out, pulling back off Bakugou’s dick with a pop, eyes full of tears. He shook his head, body still jolting from the dick ramming into his ass.

“N-No… I, I only want Kacchan like this,” he said, licking his lips as his hand stroked Bakugou’s length. It was fast and precise, fingers gripping and squeezing in just the right way to make Bakugou’s breath hitch in his throat. He leaned down and ran a slow tongue up the length, stopping to wrap around the head and tease at the slit. He looked up at red eyes through thick lashes, fluttering them as he said, “I’m only a good slut for my Kacchan.”

Bakugou’s brain short circuited for a moment, mind unbelieving of the words that just spilled from that mouth. That sweet, seemingly innocent, but purely filthy mouth that knew how to suck dick like a pro.

And the sickly-sweet smile that followed, the boy worshipping his cock suddenly coy like he knew what those words did to him sent Bakugou on the offensive, finally ready to claim Deku as his own- to destroy that fat ass and sink his teeth into his flesh and mark him as his own.

He growled and roughly pulled Deku away from his dick, fingers sinking into his hair and pulling him off the machine. He let Deku fall to the ground in a heap once again, standing over him menacingly, cock still hard and standing at attention, now gleaming with Deku’s saliva.

“You wanna be a good slut for your Kacchan, huh, Deku?” He asked, leaning down to roughly grip the boy’s shoulders, hoisting him up easily and throwing him over his shoulder. Deku squeaked in his arms, his cock brushing against Bakugou’s chest and he walked them to the teachers work station. “I’m gonna fuck your tight little ass so hard you won’t be able to walk straight for a week.”

He threw Deku down onto the table, the other boy watching breathlessly, legs squeezing together and hips bucking, needy, desperate whines falling from his lips. His bare body laid out deliciously for Bakugou to feast his eyes on, his cute cock dripping for him.

“Kacchan, please,”

Bakugou felt himself melt at the pure desperation Deku had in his voice, all for him. He wanted to abandon everything else and just fuck into his sweet little whore, to praise him for being so good. But instead, he tutted and fixed the other boy with a heated glare, finger pointing to him as he commanded, “Stay here. And don’t even think about touching that cute little cock or ass of yours or else I’ll fucking kill you.”

He watched the other boys throat bob with a thick swallow, his fingernails immediately digging into the wood to keep himself from disobeying his Kacchan.  

Bakugou grinned and nodded his approval before he stalked over to where Deku’s machine was still set up on the stool. It was still thrusting away into the empty air, wet with lube. The blonde could feel eyes on his back and he smirked, knowing that his sweet little Deku was waiting so patiently for him. He picked the machine up and brought it over to the teacher’s station, chuckling darkly at his little nerd’s surprised gasp.

He set it down in front of Deku, the dildo thrusting just shy of his pretty mouth. Green hair fell in front of his eyes as he tilted his head, eyes flicking between his Kacchan and the machine in front of him.

Bakugou stalked around the desk, eyes never leaving Deku’s.

“You’ve been such a good little slut for me, Deku,” he growled, voice low. He came to a stop behind Deku, leaning over him but being careful to not touch him as he whispered in his ear, “you think you’ve been good enough to get my dick now?”

He hears Deku gasp, hips rolling backwards, trying to find contact. Bakugou laughs and dodges his body, waiting for a response before letting him indulge.

“Come on now, darling, use that pretty voice of yours.”

A low whine came from the man under him, body crumpled on the teacher’s station before a soft whispered, “please, Kacchan,” floated through the air.

It wasn’t quite what Bakugou was expecting- he half anticipated the boy to turn and beg on his knees, to scream for him a mantra of ‘pleases’- but the way his voice cracked, so utterly desperate for him, made Bakugou abandon his original plan and show the trembling boy some mercy.  

Because if he was being honest, he was almost as desperate as him.

He quickly shucked off his pants and boxers, leaving him only in his sweaty black tank top, too impatient to fully strip himself. His hands reached out and found bare skin, Deku crying out at the slightest touch. They traveled down an expansive back, up and around to sensitive nipples. He brushed past them, relishing in the soft moan that fell from Deku’s lips.

“Deku,” he breathed, leaning down to press his chest to Deku’s back. The other boy turned his head, their lips meeting in a wet and messy clash.

Both were lost in the press of lips, Bakugou’s hands wandering from nipples to abs to navel, Deku’s transitioning from their clawed grip on the wooden table to digging into Bakugou’s flesh.

“Deku- baby,” he bit Deku’s soft bottom lip, teeth pulling on it before letting it go, red eyes enraptured by green. The other boy was looking at him from over his shoulder with such a beautiful expression- eyes full of burning lust, but mixed with admiration and awe. A look that was so purely Deku that Bakugou was sure he’d never get enough of.

“Fuck, you look so good like this. So good for me.”

Deku whined, hands scrambling to reach down to Bakugou’s cock, stroking it. Bakugou hissed at the contact, choosing to ignore the fact that Deku wasn’t told he could touch him because it just felt so good.

And when his hand led Bakugou to line up with his hole, hips pushing back just enough to swallow the head in his tight heat, eyes burning and a breathless, “Kacchan, fuck me”, Bakugou just couldn’t hold back anymore.

With a growl, he thrust into Deku, cock fully sheathed inside him, tight walls accepting him with no hesitation. Both men gasped out their partner’s name, tears spilling down Deku’s cheeks as Bakugou finally set a rough, fast pace. Skin slapping against skin sounded through the room, their moans drowning out the steady sound of mechanical grinding.

Bakugou’s hands were gripped tight onto Deku’s hips, squeezing hard enough to keep the squirming man in place, hips taking on an angle that made Deku scream. Deku’s hands were scrambling for something to grip, one coming around to grip Bakugou’s wrist, the other reaching up to grip the edge of the workstation.

“Ah, fuck,” Deku cried, body lurching as Bakugou lifted his ass just enough to thrust even deeper into him. Bakugou could feel Deku’s walls clenching around him, welcoming him in further, encouraging him to go faster. “Kacchan, you’re so good- fuck- “his hand abandoned the other's wrist, moving to spread his cheeks more, allowing Bakugou’s cock to slip through his hole with no resistance. “God, you’re so fucking big, -ah fuck- bigger than I ever imagined,” Bakugou groaned, watching his dick disappear into Deku, his hole swallowing him, sucking him in deeper. "So- ah- so much better than the machine. God, you fuck me so good." His back was arched, ass so prettily on display, Bakugou couldn’t help himself. He leaned over, never once missing a beat in his thrusts and sank his teeth into the flesh of Deku’s neck, sucking a mark there that would prove that Deku was his and only his.

“You’re fucking mine, Deku, you hear that?” he asked, lapping at the bite mark, smirking as it turned a fierce red that showed him it would bruise perfectly. Deku only moaned his approval, his words slowly muddling with pleasure. The only words that were distinguishable were ‘Kacchan’ and ‘please’. He leaned back from his neck, a finger coming up to slip into his hole beside his dick, ripping a scream from Deku.

“This is what this slutty hole was made for,” he laughed. He worked the finger alongside his dick for a few more thrusts before pulling it out, hands returning to abused hips. “fucking perfect for taking my dick.”

He looked up, watching as Deku lay boneless on the teacher’s desk, mouth open in silent screams. He leaned down and peppered a few open-mouthed kisses to Deku’s back, sucking on the skin and making sure they’d bloom into pretty hickeys. Above him, the machine was still running, abandoned, thrusting into empty air.

It gave Bakugou a perfect idea.

He slowed his thrusts, causing Deku to cry out, hips jutting backwards to try and seek out his dick, to push it further into him and entice Bakugou to fuck into him faster.

The blonde chuckled at Deku’s efforts, a strong arm wrapping around his little slut to haul him upwards, Deku’s hands immediately shooting out onto the table to steady himself. The boy moaned as Bakugou shifted even deeper inside of him with the new angle. 

Once he was certain Deku was holding himself up on his own, shaky hands, he let his grip go. He traced a hand up the other’s neck, to soft lips and into an open mouth where Deku licked and sucked on his fingers, moaning around them as Bakugou rewarded his good behavior with a hard, deep thrust.

“I think we can find a good use for this hole too, don’t you, baby boy?” He asked, fingers stroking at the slick, hot tongue. Deku groaned as he slipped his wet fingers out of his mouth, saliva streaking down his chin.

Green eyes turned to look back at him, head tilting to the side in confusion.

Bakugou’s chest clenched, wondering how Deku could be so god damn cute, even when he was getting his brains fucked out.

His wet fingers pointed to the machine that was placed in front of them.

“How bout you use that mouth of yours and show me how good you suck dick?”

Deku squeaked as Bakugou allowed him another hard thrust.

“B-but I already showed you, Kacchan,” he whined, eyes glistening. “I- wasn’t I good?”

Fuck.

Bakugou leaned forward, kissing his lips sweetly, thrusting into his tight heat with shallow strokes. He swallowed down Deku’s sweet moans, tongue gliding across wet lips before pulling away.

“Baby, you were so good. I just want to see my pretty boy choking on his dirty little machine while he takes my cock. Can you do that for me, Izuku?”

The moan that fell from Deku’s lips was so loud and broken, it sent chills up Bakugou’s spine. He knew that using his baby boy’s name would let him get anything he wanted, knew it would drive Deku crazy, make him want to please Bakugou in any way he could. He smiled, leaning forward to kiss the tear that slipped down his cheek, soft hands comforting his trembling body. Soft moans fell from his lips, like he was somehow more sensitive to Bakugou’s touch.

“Is that a yes, ‘Zuku?”

“Y-Yes,” his broken voice said, barely audible over their panting breaths and the whir of the machine. He leaned forward, lips only inches away from the thrusting machine. Bakugou resumed his slow pace, hips rolling against Deku’s ass as the man opened his lips and swallowed his machine down.

Bakugou cursed under his breath, watching his sweet Deku struggle to keep his mouth open around the thrusting machine, moaning as Bakugou pounded deep inside him. Obscene wet sounds filled the air, from Deku’s slick hole sucking Bakugou’s cock into him and the machine squelching around Deku’s open mouth.

Bakugou worked his way up to a rough and fast pace, openly moaning at the sounds Deku was making. Each thrust pushed him forward, making him choke on the machine as it rutted into his mouth.

"Do you even know how fucking pretty you look right now baby? God, I swear you were made for this. You take my cock so good," he emphasized his point with a sharp snap of his hips, dick plunging into Deku's tight ass, the boy accepting him with no resistance. His screams echoed through the workshop, bouncing off the walls and reverberating in Bakugou's ears like a symphony. He leaned down to suck another hickey onto his shoulder, mouthing at it as he whispered huskily, "'M so glad it was you in here, Izuku." 

Deku clenched unbearably tight around him at the admission, his entire body shaking in euphoria. His hands came to grip at Bakugou's, blunt nails raked across Bakugou's skin as Deku screamed around the dildo thrusting in his mouth. 

Everything was hot and wet and perfect and Deku was amazing. His hole was clenched around him perfectly, everything becoming tighter and messy as the two came closer and closer to their breaking point.

Bakugou was thrusting into Deku wildly, rhythm abandoned as he felt himself approaching his peak at an alarmingly fast rate. Deku popped his mouth off of his machine, unable to keep himself from choking on it while he was screaming for his Kacchan. Both men were gripping at each other, fingers digging into flesh as white-hot pleasure danced along their spine and through their body, skin sliding against skin.

Deku was the first to fall when Bakugou landed a hard, deep thrust in the perfect spot, his walls clenching impossibly tight around Bakugou, thick white ropes of his cum splattering across his chest and onto the work station and floor. He came with a broken scream of “Katsuki” and hearing his real name fall from those lips in such a wrecked and pleasure filled tone made Bakugou fall off the edge with him, thrusting in deep once, twice more before spilling his load inside Deku’s ass.

The two fell onto the table, Bakugou weighing Deku down as they caught their breath.

Everything was hot and sticky between them, but Bakugou could feel Deku’s chest heaving under him, could feel his dick slip out of his ass, could smell the sweet scent of Deku’s shampoo with his face buried in soft green curls and somehow, he felt like he was home.

He groaned and pushed himself off Deku’s back, lazily staring down at the mess he left the other boy in. Skin glistening with sweat, dark red marks littered on his neck and back, cum spilling out from his abused hole. Deku’s never looked more beautiful in his life.

He leaned over to grab the switch for the machine that was dropped sometime during their activities and he turned the dial until the machine stopped. Silence took over the room, save for the little gasps from Deku still trying to collect himself.

Bakugou pulled out a metal chair and slunk into it, Deku slowly groaning, hips shifting uncomfortably as more of Bakugou’s cum seeped out. He stared at the boy for a moment before he reached a hand out, gripping Deku’s arms that laid on the table, and pulled the boy easily onto his lap.

Deku squeaked in surprise, his legs immediately straddling his hips, but then melted into his arms as the blonde nuzzled into his neck, pressing a soft kiss there. His hands worked to his lower back, kneading the flesh in slow circles.

“K-Kacchan...?” Deku’s sweet, soft voice whispered. Bakugou knew that there was a question lying underneath the simple word, one of what the hell just happened between them, but he didn’t want to deal with feelings and emotions when he was this tired.

Instead, he simply cupped Deku’s cheek, turning the boy’s face towards him as he pressed a soft, simple kiss on his lips.

They both sighed as they parted, foreheads resting against each other as their breaths mixed.

“Don’t overthink this,” he whispered into the space between them, finger lightly flicking the others forehead. “we’ll talk later, Izuku.”

He heard the quiet gasp and pulled back, a small, genuine smile on his normally scowling face.

Deku was staring at him, eyes wide and shining, and Bakugou didn’t want to think abut the way it made his heart stutter, or his stomach fill with butterflies.

Instead, he smirked, hands clapping around Deku’s ass, giving him a firm squeeze. Deku gasped, hips shaking as he felt more of Bakugou’s cum slip out of his hole and run down his leg.

“Next time I’m going to absolutely wreck you with that machine of yours.”
