Make it yours

Summary:

Bakugo has become too reliant on his vibrator that when it dies suddenly mid session, his desperate, horny lapse of judgment sends him barreling to Izuku's door. 

 

They get more up close and personal than they've ever been. 

[Use of AFAB/AMAB terms for katsukis gentals; cunt, pussy, dick, etc]

Work Text:

Katsuki let out a faint whimper as he closed his eyes, trying to concentrate on chasing his orgasm. Adam's apple bobbing as he choked out more whines. 

Each sound being slowly coaxed out of his aching throat as he stilled his hand as much as possible, his vibrator whirring harshly against his clit. Katsuki whining when it would slip just a little too much due to his wetness. 

It usually took Katsuki a while to reach that peak-- he had to concentrate his breathing and relax his muscles as he worked on his twitching dick, the last 2 years of HRT leaving his clit chubby, and much more dick like. To say he was rock hard was an understatement. 

Katsuki's hand cramped as he felt himself getting closer and closer to cumming, breathing shakily through his nose. It was rare that he ever managed to squirt, but he was constantly chasing that high when he jerked off-- katsuki rasped out a pathetic moan just as he was about to cum, hoping to god Kirishima was not hearing this from the next door over. 

Just as Katsuki was about to cum, his vibrator-- with a pathetic rumble turned off suddenly, leaving Katsuki's dick twitching as he whined loudly, gasping out a pathetic “no--” as he desperately tried to keep going, heaving hard. All his concentration leaving his body as he tried to turn his vibrator back on while in his hand. 

No luck, Katsuki shuddered and tossed his vibrator aside, desperately trying to finish the job with his fingers-- leaving him with nothing more than a desperate ache in his pussy, clenching around nothing.

“Mother fucker” he gasped out, and sat up quickly, he could feel more slick gush out of him with his rapid pulse.

Katsuki stood up on shaky legs. His head swirling with desperation. It's not like he's gonna go next door and beg Kirishima or Shoji to finish him off. Thatd be fucking absurd. Not only would it tarnish any existing relationship with them, but it would be considerably more awkward if they told him to fuck off. 

Katsuki stepped out of his room with sheer determination swirling in his gut. Or it was the impending orgasm that was waiting for him just downstairs.

Swallowing his pride (and something else hopefully) , Katsuki shuffled down to the second floor with much urgency. He didnt know why his first option was stupid deku, but deku was considerably easier to convince and somehow less embarrassing than fucking Kirishima or anyone else, girls included.

Besides, Deku should be thankful for this grand opportunity of Katsuki's pussy.

He knocked on Izuku's door with haste, his face flushed and insides twitching with each passing second. 

He could hear the faint rustling and click of the lock, the door opening and izuku peeking his head out

“Oh-- kacchan..?” Izuku asked, rubbing his eyes. “What's up..?” He yawned "you're never awake at this time” 

“I need you for something” katsuki rasped, arousal burning in his gut “lemme in.”

Izuku looked a little perplexed but nodded anyway, opening the door for katsuki as he walked in.

Somehow he was starting to wonder if this was a poor decision.

“What did you need, kacchan?” Izuku asked sleepily, taking a seat on his bed. 

“I need you to make me cum” he said matter of factly. 

“Oh, okay, i can…” izuku paused, and then katsuki could see the blood gush to his head as his face went bright red, eyes wide as he sputtered

“Y--you what!? I- kacchan!” He yelped, covering his mouth in shock “you can't just come into my room and-- and ask me for something like that!!”

“Tch.. why not?” He asked “and keep it the hell down” 

“B--because we're friends! Childhood friends, kacchan!” He whisper yelled “Childhood friends don't do something like-- EEK!” Izuku cried as Katsuki walked over to him and pushed him down on his back, a fire burning in his eyes and guts.

“my fucking vibrator died and i'm gonna kill you, myself and everyone in this building if i cant fucking cum, deku.” Katsuki scowled “either take this chance or ill go to someone else”

“N-no! I.. i just-- i wanted this to be more romantic or something!” 

Katsuki blinked

“Hah..?”

Izuku blushed wildly, covering his whole face with his arms and hands

“I--i mean i always imagined kacchan and i being intimate! B-but i thought it would be different, like maybe i finally got the courage to ask you out and we went on a few dates-- b..before we had our first kiss and then..” izuku sputtered, he looked at katsuki through his fingers and yelped

“W..where are your pants, kacchan?” He asked meekly.

“Doesn't matter, i dont fucking need em” katsuki saif, crawling onto izukus lap

“D--dont you think we should talk more!? Maybe about boundaries-- or um.. consent..! I totally consent but y'know what if you're making a choice you'd regret! I'd always been certain kacchan would never wanna-- with..with me..” he said

Katsuki sat bare on Izuku's lap, he could feel izuku already hard underneath him.

“Stop fucking assuming shit all the time.” Katsuki grunted, gripping onto the front of Izuku's shirt

“a..am I dreaming?” He whimpered, trying to keep his hips totally still, it didn't help that Katsuki could feel Izuku's dick twitch with his intense pulse. 

Katsuki leaned down and forced his lips against Izuku's, coaxing a whine from him as he squeezed his eyes shut, his hand coming to grip Katsuki's hip to stop him from moving.

“M--kacch..nghhh” izuku moaned into katsukis mouth as they kissed sloppily, katsuki's tongue aggressively fighting against Izuku's, who was rather pliant as katsuki licked into his mouth. 

Katsuki pulled back with a heavy breath, his hand had migrated to Izuku's neck in the time they were kissing, leaving izuku gasping, his pupils blown wide 

“K..kacchan… please let me eat you out?” He begged on baited breath. Katsuki's eyes went wide. That response was probably the last way he figured he'd get his rocks off tonight. 

“Tch.. have you ever even eaten someone out??” He scoffed at izuku, pressing his thumb against Izuku's Adam's apple, he swallowed thickly and nodded his head quickly, leaving katsuki even more shocked 

“Wh.. who!?” He asked, baffled that this damn nerd had more fucking experience than he did. 

“W..well.. me and ochako were..experimenting for a while..” izuku muttered “sorry” 

Katsuki bit his lip, he wasn't sure if the idea of izuku having experience made him more irritated, or way hornier.

Katsuki swallowed down his feelings, and sat up on his knees. “You better be fucking good at it then.” He huffed, throwing himself onto tue middle of Izuku's bed, pushing him with his foot to urge him to hurry up. 

Izuku was quick to sit up, and crawl between Katsuki's legs, his dick tenting in his shorts eagerly. 

“Thank you kacchan” izuku said pathetically “I've been wanting this for so long” 

“Just shut up” Katsuki huffed, his chest flittering with each gaspy breath he took. His heart pounding as izuku pushed his legs open and back, his pussy throbbing at the action alone

Izuku's eyes were trained onto Katsuki's clit, it twitched with eagerness as Izuku's warm breath ran over his genitals. 

Katsuki was just about to scold Izuku for taking too long when he leaned forward and latched his lips right onto his dick, a moan ripping through Katsuki's throat.

“Ungh--- deku--” he growled low..

Izuku lapped at his clit, kissing the sensitive nub as he stuck his tongue out and licked up at Katsuki's already slick covered pussy. 

“Nnghh… deku-- fuck!” Katsuki yelped, clutching the sheets under him.

“Kacchan…shut up” izuku muttered into his wetness “you're gonna get us caught” 

“D..dont fucking tell me--- unghh!” He tried to argue back, but Izuku suckled on his dick with his tongue and lips, rendering Katsuki's voice useless other than his whiny moans. 

Katsuki bit his hand in a desperate attempt to lower his voice as he felt Izuku's fingers prod at his entrance.

“D…dek…ughhnn” he groaned “Izuku please” 

Izuku stopped and looked up at Katsuki from between his thighs…

“Kacchan.. can you say my name for me again?” He begged, his hand holding his leg massaging the meat of his inner thigh.

“F..fuck.. just continue you fucking nerd” katsuki said, wiggling his hips in desperation.

Izuku buried his face back into Katsuki's pussy, earning a gush of slick as Katsuki cletched down onto Izuku's fingers. 

Katsuki couldn't stop the pathetic whimpers that were clawing its way from his throat, his hips twitching in desperation as Izuku swallowed down his juices and his tdick. 

Katsuki's hands found his hair in desperation, grasping at his hair, hands unsure on pushing or pulling, opting to keep him still..

“Iz..izu…unngh..” Katsuki cried, feeling the heat in his stomach thicken, his abdomen shuddering with his desperate gasps “no.. i'm Gonna cum--” he pleaded, his hips twitching and pushing closer to izuku.

Izuku moaned into Katsuki's pussy as both hands came to wrap around Katsuki's waist, holding him down as Izuku's wet lips ravaged Katsuki's hole and dick. 

Katsuki's eyes fluttered open, desperately trying to look at Izuku but he was too focused on the task at hand. Katsuki then noticed the way Izuku's own hips stuttered where he lay flat on the bed, his hips pressing and dipping into the bed where he rubbed his aching dick into 

This made katsuki gush just a little more. His hand squeezed Izuku's hair as he moaned.

“Tch… you're getting off to eating my-- unghh.. p-pussy?” He asked, trying to force a meaner tone but it came out more coy and embarrassed. 

Izuku turned his head up to look at katsuki with big doe eyes, his lips tight against his dick before he popped off with a whine

“I..i just love kacchan so much" he gasped pathetically-- his hips twitching as he moaned “i cant help it…sorry kacchan” izuku whined as he latched back onto Katsuki's pussy, his movements getting more aggressive. Katsuki's insides throbbing harder and faster. He eas gonna cum just from izukus stupid pathetic face

Katsuki cried out, his dick twitching inside Izuku's hot mouth 

“Fuck--- ughh-- i'm Gonna fucking cum” he croaked out, hips stuttering “this stupid fucking nerd…uh-- hhn-- is.. is gonna make me…” katsukis voice trailed off as tears began to well into his eyes, his throat tight as he arched desperately on the bed, trying to claw away from the intense pleasure punching at his insides now. 

“N-- no!” Katsuki cried “i.. I'm Gonna-- f..fuuuck!” He bit his tongue as he cried loudly, positive that the entire second floor of the dorms was getting an intense show. 

Izuku whimpered as he lapped quickly at Katsuki's dick-- Katsuki's hips trying to rip out of his grasp as he felt his pussy convulse hard and quickly-- and an intense gush of liquid assaulted izukus lower face.. he just made katsuki squirt… 

That alone was enough to have izuku cumming into his sheets, tears wracking his body as his own orgasm rippled through him, gasping and stuttering as Katsuki gushed an absurd amount of fluid onto his face and into his mattress. Katsuki crying could be heard above him as he slowly came down from the high. 

Izuku, still shaking, gave a taut kiss to Katsuki's dick and slowly pulled his face away as he sat up, his sweats covered in his own cum as his dick twitched at the sight of Katsuki. How he was still so hard after an intense orgasm like that is absolutely beyond him. 

Katsuki was staring at the ceiling with fluttering eyelashes and tears in his eyes, rasping and twitching with the lasting effects of his intense orgasm. 

Izuku crawled forward, leaning over Katsuki to look at him closer, his eyes snapping to him, a look of desperation.

“D..did i do a good job, kacchan?” He asked, he didn't care how stupid he sounded, he was absolutely putty in Katsuki's hands.

Katsuki's eyes fluttered close as he took in a sharp breath, exhaling trying to catch his thoughts.. 

“Sh..shut up” he said with a pout in his lip. That was kacchan for “you did great” 

Katsuki opened his eyes and scanned Izuku's face, then down his body, towards his dick, he could see katsuki's pupils dilate

“You're still hard..?” He rasped “you horny freak” 

Izuku's dick throbbed at that. It was an understatement to say izuku loved when Katsuki was kinda mean to him. It was the kacchan he loved the most. Izuku was more than happy to be some dog only beckoned when needed to katsuki. 

“I'm sorry kacchan… youre just so…beautiful, i cant help it when i see you…” he crawled a little closer, katsuki's legs still open.. he made no attempt to close them as izuku got close, his dick hanging heavy just above katsuki's beautiful pussy.. he could easily take kacchan as his right now.. but he didnt want to do anything he didnt want.

Izuku could see Katsuki's resolve slowly leaving his body as he stared down at izukus dick, just above his own..

Katsukis eyes snapped back up at izuku.. his face reddening as his lips contorted into a cute pout.. 

“Fucking--- whatever.. put that damn thing inside me.” He groaned, his hand coming up to grip Izuku's forearm where it was positioned next to him. 

Izuku blushed wildly and nodded quickly-- his free hand coming to pump his dick a few times, before he shuffled as close as he could, and the tip of his dick kissed Katsuki's. Earning a whine from the both of them.

Izuku gently traced his dick up and down Katsuki's chubby clit, katsuki shuddering in return-- slowly izuku brought the tip of his dick down slowly, katsuki's folds already super slick and wet from his orgasm, it was difficult not to just slide all the way in with much ease and without much pushback

Izuku's tip kissed at Katsuki's fluttering hole, it took all his strength to not claim Katsuki as his forever. Nobody was allowed to grace this beautiful body or soul of his ever again.

Izuku slowly pushed forward, the action earning a change in breath from Katsuki as he exhaled sharply through his nose. Slowly pushing in, it was so wet and slippery that in a gentle push izuku was sucked already halfway in. 

“K..kacchan..” izuku pleaded “you're so perfect… i love you kacchan..” he whined, not caring that he was spilling his guts to him while almost fully buried inside. 

“Fuck--” katsuki growled “you're so.. damn pathetic..” 

Izuku nodded quickly, blush creeping down his neck

“I'm always pathetic when it's Kacchan..” rambled “ill-- nn.. ill always be yours to use…”

Katsuki's pussy fluttered around him at those words. Did he really like this kind of talk as much as he did…?

Katsuki's hand suddenly gripped Izuku's jaw, forcing him to look at him. His face was red, his brows knitted together, a scowl on his face… but he didn't look angry… not in his eyes. 

“Yeah?” Katsuki rasped “you gonna be a good boy and fill me up?” 

Izuku thought he couldn't get harder-- he almost came on the spot at those words. He tried to nod in Katsuki's tight grip. 

“Yes kacchan-- i'm Always your good boy-- oh fuck..” he cursed as katsukis leg came up to wrap around him and push his hips forward, finally burying izuku to the hilt. He wanted to cry and hold katsuki, this was really real life right now. He was inside katsuki. His childhood love.. 

“Go on then… show me what you can do, i-zu-ku~” he purred, all of the resolve left Izuku's body on a whim. He pulled out slowly, and sat up, his dick sad and twitching as he left Katsuki's tight heat. Earning a whimper from katsuki even in frustration.

Pulling katsukis leg from around him, Izuku pressed katsukis legs back and against his chest, earning a strangled gasp from Katsuki.

Izuku quickly kicked his shorts off all the way, and  leaned over katsuki, his pussy twitching at the exposure and cold air. 

“Hold your legs for me, kacchan..” he said shyly. Katsuki was quick to react, his arms wrapping around the back of his thighs to hold his legs to his chest.. his breath hitched as izuku ran his dick across Katsuki's wet and twitching cunt. Giving a few slaps of his dick into Katsuki's clit, ripping a whimper from Katsuki's throat as Izuku positioned his cock against his hole again. 

And dove right in. Katsuki gasped loudly. In this position izuku was deeper than he thought he'd ever be. He almost wanted to cry of pure joy then and there..

But he had a task-- and that was to fill kacchan up. 

Izuku's heart fluttered at the idea. Pumping his hot cum into katsukis womb.. the potential danger of getting kacchan pregnant-- he rocked his hips slowly, basking in the idea… maybe when they're older… but the idea of katsuki coming to him, telling him that izuku got him pregnant, it made his cock throb..

He really is perverted.. 

Izuku rolled his hips, earning quiet whines from Katsuki, slowly raising his hips, the quiet squelch of where they were intimately connected.. 

Izuku thrust back down hard, katsuki letting out a loud moan.

“Unghh!” He cried, pussy fluttering desperately around izuku. 

“Youre doing great kacchan..” izuku muttered sweetly, pulling his hips back again and slamming down with that same heat. “You're taking me so well…” 

Katsuki whimpered and nodded, gasping and moaning with each thrust. Izuku was certain everyone was gonna know about their little late night escapade after this.. 

Izuku adjusted his position, instead of basically planking over katsuki to fuck him, he sat up a bit, right across katsukis thighs, pushing into him again slowly, holding him down in a mating press. 

This was the best way to fill kacchan up just like he wanted. 

Katsuki cried as izuku bounced his hips over katsukis, his dick drilling deeper into his pussy with slow, rhythmic pumps. 

“Kacchan…nnghh” izuku pleaded “thank you-- i love your pussy so much-- i'm So thankful..” he weeped as he pounded into him, his pace growing faster and more desperate. 

Katsuki couldn't even grunt out a word, the wind being knocked out of him with each thrust of Izuku's hips, he could only gasp and moan loudly, no longer caring that anyone could hear. They should all be thankful for this blessing they get to witness. 

“Nnghh!!” Katsuki cried with every sharp thrust, Katsuki gushing more slick with every push of Izuku's cock inside of him, desperate to make room. 

“I love you kacchan--” izuku rasped, the wet and quick slapping of their thighs together, Izuku's heavy balls smacking against katsuki's ass as he was pounded into the sheets like he was nothing. 

“I love.. lov…hnnn..” he whined, tears welling in his eyes, he was about to breed katsuki-- and katsuki was absolutely okay with it.. “I love being your toy kacchan.. i'm only good for this” he rambled, his hips stuttering as he thrusted faster, his stomach coiling with an intense and searing heat. 

“Fu--uuck!!” Katsuki yelped, his hands crackling with sparks. Katsuki was filled with so much pleasure he couldn't even control his quirk… it made izukus heart flutter “fucking--- cum in me izuku!” He cried out, tears streaking his face from the overwhelming pressure in his gut. 

Izuku whined, his hips stuttered as he felt katsuki squirt for a second time that night. His pussy tightening around Izuku's dick like a vice. He was seeing stars. 

With katsuki's loud moans and convulsing walls, Izuku's hips stuttered as he groaned out “katsuki” on a heavy breath, his vision going white as he spilled deep into Katsuki's womb. Tears spilling as he came, his hips still moving with harsh thrusts. He could hear katsukis sobbing underneath him, past the loud slaps and ringing in his ears. 

Every last drop was slowly squeezed out of izuku.. gasping harshly. He didn't want to ever pull out. He wanted to stay here and breed katsuki's perfect hole endlessly until he was certain he was pregnant. 

Sadly, the weight of his intense orgasm started to crush him, and if he didn't get his dick out of katsuki now, he may never. 

So with a whimper from both of them, izuku pulled back, katsuki gushing out a little more squirt at that, izukus sheets soaking wet now… he watched as katsukis pussy pulsed and pushed, izukus cum slowly leaking white from his hole..

Izuku wanted so badly to bend down and eat it out of him-- but Katsuki's crying was evident enough that he was probably done. 

K..Katsuki's crying?

Izuku's eyes widened as Katsuki's arms released his legs, letting them fall back onto the bed.. his chest stuttering with his gasps and cries. He quickly covered his face when he realized izuku was staring at him wide eyed. 

“Kacchan?” His voice trembled worriedly. Did he do something wrong? Did he hurt him and not even realize?? “A..are you okay? I'm So sorry i should've--” 

“Deku..” he rasped. Izuku's heart hurt. He was back to deku.

“Yes kacchan?” Izuku asked, scared

Katsuki was quiet for a minute… as he slowly sat up on shaky arms..  wiping his tears away. 

“Did you mean it when you said you loved me.” He asked flatly. It was hardly a question, more of a threat for a response

“I--” izuku fumbled over his words. He couldn't tell what it was kacchan wanted to hear… did…Kacchan not like it?

Izuku swallowed down his fear. He should just tell the truth. Even if it ruins his relationship with Katsuki forever.

Izuku hung his head and stared at his hands, intertwining nervously.

“Yeah..” he muttered

“Tch…” Katsuki sucked at his teeth, he was quiet for a moment. Izuku was ready to be blasted to hell or something “you say it like it's A bad thing.” 

Huh..?

Izuku looked up at Katsuki, shocked. 

“Kacchan do you---” izuku murmured

“Shut the hell up.. i'm not fucking saying anything.” he growled, scooting over to the edge of the bed, trying to stand but his legs trembled, unable to even hold his weight.. he groaned.

“You fuck like a damn animal.” Katsuki grumbled..

“S..sorry kacchan i just..couldn't help myself..” izuku said, scooting over to the edge to also sit next to katsuki.

Katsuki huffed, and that's when he heard a faint shuffling behind the door. Katsuki's body stilled. 

“Izuku” he said 

“Y..yeah?” 

“The door” 

“The doo…” izuku looked over at his bedroom door, and stared at it before slowly getting up and quietly walking to it. Well, it was obvious considering how loud they were. Someone was probably going to creep on them out of curiosity. But the embarrassment weighed heavy on his soul. 

He stood still for a moment longer when he heard a faint "why'd it get so quiet?” and then a panicked murmur, and the heavy tap of feet as whoever was behind the door scurried off, and a door shut. 

Izuku swallowed nervously and peaked his head out, the hallway empty. Gently shutting the door. 

“I think i'm gonna have to crash here for tonight” katsuki huffed, izuku turned to look at him, his legs trembling.. 

“Let me um.. change my sheets first, kacchan.. then we can go to sleep..”

Izuku's stomach churned with nervousness and somehow excitement… Does this mean katsuki was really his?

He's gonna hope it is.

 

-------

 

The next morning was awkward beyond awkward. Izuku and Katsuki sat on the couch being scolded by Iida, who was blushing down to his neck as he reprimanded them on dorm etiquette and safe sex. 

Katsuki seemed rather unfazed as he crossed his arms, izuku sweating bullets as their embarrassed classmates looked on at the scene. 

Yet in his deeply perverted heart, he was rather proud he was ever capable of making katsuki moan so loud the whole dorm heard it. 

Something tells him he will happily do it again.
