Bakugou was getting more than a little frustrated if he was being completely and totally honest.
That might be underselling it.
He was fucking pent up .
See, he loved his boyfriend. Kirishima Eijirou was fucking sunshine in a person’s body who always remembered the kind of chips that Bakugou liked and snuggled up with him when it was too fucking cold because his huge ass body was a fucking space heater and he ate ass like a champion . But they’d been together for three years now and they hadn’t taken that last little leap in their sex life.
It seemed like any time Bakugou got up the courage to want to ask for Kirishima to please, for the love of god, stick it the fuck in already, he’d get distracted by some other activity or some stupid classmate bullshit would come calling.
They’d done pretty much everything else short of one of them wearing a fucking corset and whipping the other and Bakugou was pretty sure he’d be the one talked into the corset and like fuck was he leaving that possibility open. He just really, really fucking wanted to cross that threshold. And yeah for all the fucking schmoopy reasons of feeling connected and shit but he also knew Kirishima’s dick pretty well at this point and he was excited for the challenge of getting it into his ass.
Because fuck it was just big enough to make his jaw ache when he got Kirishima to fuck his face and he didn’t care that he was almost drooling in class at the thought of it. He liked fucking his boyfriend, that shouldn’t be a shock to his fucking classmates at this point, they weren’t exactly shy .
He came up with his plan in math class.
Riling Kirishima up was easier than one would think. Sure, the redhead was patient the majority of the time, but Bakugou had learned how to crawl under his skin. How to pull out the biggest reactions from him, make his face go as red as his hair and make his hardening crawl up his arms in involuntary spasms. So he spent the day dragging his hands over Kirishima when he could, resting his hand in his back pocket, sliding into his lap during lunch.
Kirishima was a sucker for touching. It was one of the ways Bakugou could loop his boyfriend around his little finger for an entire day. The more affectionate and demonstrative he was, the more likely it was that Kirishima would give in to any request he had. Especially on a day like today.
A day where, in between classes, he dragged his boyfriend into a closet to catch his lips roughly, moaning into them. Kirishima made some kind of muffled noise but he groaned and leaned into Bakugou’s body, always happy to enjoy a little clandestine making out when they had the chance. He practically lifted Bakugou off his feet, the blond loosely wrapping his legs around Kirishima’s hips with a happy sound, tugging on his hair.
“Mmmh what’s all this about?” Kirishima panted between kisses, whining a bit as Bakugou tugged his hair again, sucking at his tongue. Bakugou squirmed in his grip until Kirishima put him down, wrapping his boyfriend’s tie around his fist and tugging until he could whisper in his ear, nipping at the shell.
“I’m excited,” Bakugou murmured and Kirishima shivered and tilted his head a little.
“A-About what?”
Perfect.
Bakugou let out a soft, breathy sigh, pressing the palm of his hand against the front of Kirishima’s pants and rubbing, making the redhead shiver, feeling his dick jump a bit at the touch. Time to go in for the kill.
“About the fact that, after class today, you’re gonna fuck me,” Bakugou murmured, tugging on Kirishima’s earlobe with his teeth, hearing the telltale sound of a seam ripping as Kirishima’s arms rippled with hardening. He backed off then, looking at Kirishima’s wide eyes and pen mouth, the look in his eyes screaming arousal and embarrassment all at once and Bakugou loved it. “I’m excited,” Bakugou purred, running his tongue over Kirishima’s lower lip before letting go of his tie and leaving him gaping in the closet.
He was smug the rest of the day, licking his lips in Kirishima’s direction and feeling his burning red eyes drilling holes into his clothes all day. Hell, he knew he had Kirishima dancing on that low end of being hard all damned day if the minorly disturbed look on Kaminari’s face was anything to go by when he caught the way the two were eye-fucking each other.
Bakugou practically ran back to his dorm when class ended, Kirishima hot on his heels and he grinned wide and wild when he was grabbed by the waist and tossed over Kirishima’s shoulder on the way to the elevator, laughing in an almost giddy way, the wheezing cadence echoing in the hall. He didn’t give a shit if anyone saw, Kirishima had ruined his fucking reputation ages ago anyway.
“Fucking tease,” Kirishima practically growled, hand coming down on Bakugou’s ass as he hopped in the elevator and hit the button to their floor, none of the other boys daring to ride with them.
“You fucking love it,” Bakugou panted, licking his lips, “and I had to get my point across or your slow ass would never get in gear.”
“Maybe I believe in romance,” Kirishima said, walking down the hall and carrying Bakugou like a fucking war prize. The blond squirmed happily, licking his lips a little and smacking Kirishima on the ass hard to make him yelp.
“You can romance me later, you’re fucking romantic all the time,” Bakugou said, wiggling free and grabbing Kirishima by the wrist, dragging him into Bakugou’s dorm and grabbing his tie to toss over the doorknob before locking the door behind them. “Right now I want you to fucking give it to me, we’ve waited long e-fucking-nough.”
Kirishima groaned and Bakugou drew him into a kiss before he could speak. Bakugou had enough talking. He just wanted touch. Before Iida could come up and yell at them for inappropriate behavior or whatever.
Bakugou tugged at Kirishima’s hair, arching his body up, wrapping a leg around him to bring their bodies tighter together, practically climbing his boyfriend who got the hint to slide his hands onto his ass and lift him up. And fuck Bakugou loved how big Kirishima had gotten over the last year, he’d shot up and filled out, huge in all the right ways and Bakugou was sure he should have hated it but it was so fucking hot. He parted from the kiss with a whine, leaning back and holding himself up with his legs, shoving Kirishima’s jacket and shirt off, laughing as the taller hero-in-training adjusted to keep his balance.
“Fuck, you’re huge,” Bakugou murmured, running his hands over Kirishima’s chest and the redhead laughed a little, walking them to the bed and pressing Bakugou onto it, opening up his shirt with an eager grin.
“Nothing compared to your tits,” Kirishima teased and the blond huffed, about to yell that he did not have tits but then Kirishima was dropping rough, scraping kisses over the curve of his chest and Bakugou forgot what he was going to bitch about. In fact, he laced his fingers through Kirishima’s long red hair and tugged, pulling him tighter to his body and whining when he felt his teeth pull against his nipple.
God it felt nice. They’d definitely done this before though, Bakugou moaned at the memories and the reality of it. They’d spent hours with Kirishima torturing his chest until the skin was so raw his costume was uncomfortable and stimulating all at once.
But it was more exciting right now because they were actually building toward something bigger, something Bakugou had been dreaming about for fucking months, hell, probably since he and Kirishima had first fucking met. Bakugou knew what he was about goddammit.
He tugged Kirishima back up for more kisses, pushing him back after a minute to tug at his pants. “C’mon and get fucking naked,” Bakugou growled and Kirishima laughed a little at that.
“You’re so impatient, babe,” Kirishima said, standing to struggle out of his pants while Bakugou did the same, tossing his boxers and uniform slacks into the corner almost aggressively along with his socks.
“Fuck you,” Bakugou said, getting onto his knees and reaching up, grabbing Kirishima by the hair and tugging him down into more kisses, feeling the perfect way their bodies slid together and moaning loudly at the feeling as Kirishima leaned into it and pressed him back down to the bed with a bounce.
They laughed breathlessly into each other’s mouths before Kirishima pulled back, pressing some of his hair, falling loose from its gel, back over his ear. “But, for real though, ‘Suki,” he said softly, “you sure you’re ready? I mean, I know we’ve done a ton of other stuff but I don’t want you to feel like you gotta do this for me or anything.”
Bakugou snorted, cupping Kirishima’s cheek gently. “I am,” he said, voice dead serious, looking into Kirishima’s eyes as he said it because as much as Bakugou hated talking about his feelings he knew Kirishima needed to hear it, “I want this with you, Eiji.”
Kirishima grinned that bright, sunshine smile and leaned in for a more languid kiss, coiling large arms around Bakugou’s body as Bakugou gripped onto him tightly, fingers digging into his shoulders, when they parted to breathe Bakugou smirked up at him. “Now are you gonna stretch me out for that monster you call a cock or are you gonna watch me do it because I am fucking okay with both.”
Kirishima broke down into giggling for a minute. “Dude, the last time I watched you finger yourself I came so fast,” he said with a snort, nipping at Bakugou’s neck while the blond tugged at his hair roughly, “gonna have to do it myself...wait, do we have condoms?”
“Why would we need that?” Bakugou rolled his eyes, “I’ve only ever been with your happy ass and I know that you’ve only been with me and if I get knocked up then we have like, a million other issues to worry about.”
Kirishima cackled at that, wiping at his face. “Stop! You’re gonna make me lose my erection,” he said with a snicker, “and I meant for clean up.”
“You’ll just eat me out after,” Bakugou shrugged before smacking Kirishima’s shoulder and spreading his legs. “Now get to work, Eiji, I want you to blow my fucking back out.”
“Yessir.”
Bakugou grinned wide and happy as the redhead reached for the lube, running his hand over his body and gripping his own cock to give it a few quick strokes as he watched the play and flex of muscles in his lover’s body. It was so fucking unfair how hot Kirishima was, but he was all Bakugou’s so that made it mildly acceptable.
He was about to bitch about Kirishima taking too long before he felt the first lubed finger against his ass, Kirishima’s teeth dragging over his inner thigh as the redhead worked his finger in him slowly. Bakugou hummed at the familiar stretch, legs spreading as wide as he could allow, letting Kirishima take his time. It just felt so fucking good to be filled like this, for Kirishima’s rough fingers to work him gently, every brush over his prostate sending little jolts of heat through Bakugou’s skin, the blond tossing his arms over his head to grip the headboard because this always drove him nuts. Watching Kirishima nip and suck at the sensitive skin of his thighs while he worked his ass open.
“Suki,” Kirishima murmured, slowly pressing in a second finger and watching as Bakugou arched his hips into the familiar feeling, “you’re so fucking hot like this. So tight too. God,” he paused a little to work his fingers in deep, rubbing circles into Bakugou’s prostate and making the blond toss his head to the side with a ravaged moan, “don’t know how I’m gonna deal with it, finally getting to fuck you. Finally getting to see what you look like begging around my cock.”
Bakugou moaned a little, tugging at his own hair and arching his back. It was always so fucking intense when Kirishima fingered him like this, avoiding his cock while working him open on his fingers, playing with his prostate until the gland felt swollen and over sensitive. Bakugou felt his thighs tremble as Kirishima added a third finger and leaned forward, one of Bakugou’s legs up over his shoulder as he caught Bakugou in a kiss, tasting the moans tripping off Bakugou’s tongue and it was a familiar position for both of them.
Normally, Kirishima would finger Bakugou open until the blond begged and pleaded for a hand on his dick to send him over the edge, each press of his fingertips making pre-cum slip from the tip. Bakugou pulled himself from the kiss with a loud moan, panting, hips shivering. He tilted his head to look down, watching as Kirishima added a fourth finger for good measure and Bakugou’s eyes rolled in his head, fists clenched to keep from blowing up the headboard.
“F-fuck, Eijirou,” Bakugou moaned out, the sound cutting off as his body was rocked by the next few thrusts of his fingers, gasping and groaning, “f-fuck, ‘m ready, put it in me, nnnh, I w-want more!”
Kirishima audibly swallowed, kissing his ear and slowing his fingers down. “Y-you tell me if it hurts,” he said quietly, “or if you need me to stop, okay?”
“I will! I fucking will just get on with it or-” Bakugou was cut off by the sight of Kirishima adjusting back between his legs, smearing way too much lube over his cock. God, was it always that big? It looked huge like this, the tip swollen and red with arousal as Kirishima gently ran it over his stretched hole. It was intimidating and exciting all at once, Bakugou reaching down to grab his own thighs and pull them up toward his chest, giving his boyfriend more room to press inward and Bakugou gasped and tilted his head back into the pillows.
It was so much bigger than even four fingers, the burn that followed making Bakugou’s thighs quake as Kirishima hooked his legs into the crooks of his elbows. But the burn was almost just as amazing as the pleasure that followed in its wake, making the blond gasp for air as it felt punched out of his lungs. He could feel pre-cum dripping on his stomach, the slow push forward until their hips were flush and tight.
Bakugou opened his eyes, when did they close, and looked up at Kirishima, face flushed and sweat breaking over him. He grabbed onto his lover’s hardened shoulders, amused and turned on by the look on Kirishima’s face, the redhead looking down at where they were connected in almost reverent awe.
“Fuck,” Kirishima breathed out, “Katsuki.” His voice was pitched in a pleasured whine, swallowing heavily, clearly struggling for control and Bakugou grinned, flexing his legs and tightening around Kirishima with a loud moan of his own, feeling the way it forced him closer to his prostate.
“Mmmh, Eiji,” Bakugou moaned back, tugging his hair until he was practically bent in half and Kirishima was rolling his hips in tight little circles, grinding into him and making those sparks of pleasure burn into a wildfire under Bakugou’s skin. He kissed Kirishima deeply and moaned, rocking back down onto Kirishima’s cock, feeling the way he was stretched around it and loving the sensation. He was so fucking full and even his skin felt too tight but in the best fucking way possible.
He tugged Kirishima’s hair until the redhead actually began to thrust into him, slow and testing, trying it out but also seemingly taking his time. Because Bakugou could feel the throb in his boyfriend’s cock, how closely he was dancing on the edge just from this. “Eijirou,” he breathed out between kisses, gasping and whining when Kirishima dipped his head to bite and kiss at his neck, adjusting his angle until Bakugou let out a loud, wailing cry, the blunt pressure on his prostate making everything ache and go tight in the best way.
His eyes rolled in his head as Kirishima’s motions grew more confident, less afraid of causing him pain. And Bakugou wailed with it, pleasure and pain sparking up and down his spine, the sensations roiling in his lower abdomen with every head-on thrust. Bakugou could swear he heard someone crying out loudly, could feel small explosions popping in his palms against his boyfriend’s hardened shoulders, one hand dragging his nails down Kirishima’s broad back.
It was overwhelming, how close they were together, how good it felt to be owned like this, Kirishima’s breathless praise whispered in his ear over and over until Bakugou felt full to bursting, rocking down into every thrust wildly, needily, like he couldn’t stop or he would fucking explode and take the whole block with him.
Bakugou chanted Kirishima’s name over and over again, the words punched out of him as they moved faster, vaguely aware that the bed was slamming into the wall repeatedly but he could not give less of a fuck. No, his whole world narrowed down to the feeling of Kirishima slamming into him, to the feeling of his lover’s moans against his neck and the tremors in their bodies. Bakugou felt that heat building higher and higher and higher, head tossed back into the pillows, shaking it as he didn’t know what to do with it, where to go for more or to escape and soon he was cumming so hard, mouth open on a piercing scream and hands letting off blast after blast on Kirishima’s hardened back.
And all the while he was semi-aware of the fact that Kirishima was cumming too, moaning and groaning into Bakugou’s neck, biting his collar hard enough to bleed and that extra little sting sent Bakugou into a smaller, weaker orgasm that had him whining and panting.
When they kissed it tasted like victory, like a milestone, and Bakugou promised himself that when he could feel his legs again they were going to to this again.
Kirishima pulled back from the kiss, still inside of him and smiling, about to open his mouth before someone knocked loudly at the door.
“Bakugou-kun! Kirishima-kun!” Iida’s voice shouted, “we heard slamming and explosions. Is everything alright?”
Kirishima’s entire face went pale and Bakugou smirked, big and wide before opening his mouth.
“Oh GOD, EIJI, HARDER!”
They had never heard Iida run so fast before.
