Bakugou Katsuki was not tiny. He was not small.
Just to set the fucking record straight.
He was one hundred and seventy-seven centimeters tall, which was not fucking short, even including all the quirks that really fucked up the national average height of Japan. He weighed eighty-four kilograms, with like negative body-fat, solid goddamn muscle. He could stand next to a good two-thirds of the population and look big as fuck. Not to be fucked with. He was no All Might, sure, but plenty of villains literally shit or pissed themselves when he towered over them.
And then there was goddamn Kirishima fucking Eijirou, who really had the fucking nerve, audacity, and gall to become a fucking mountain.
When they graduated from U.A., yeah, okay, the guy had been a few centimeters taller and had certainly packed on some muscle. Bakugou could grumble about it, but whatever, it was acceptable, and it made Kirishima an even stronger, even better hero.
Three years motherfucking later, and Bakugou had to deal with this shit.
Un-fucking-acceptable.
Kirishima was almost twenty goddamn centimeters taller than him, and outweighed him by more than thirty kilos.
Like he said, un-fucking-acceptable.
When they were in public, or around friends, Bakugou literally couldn’t seem to help himself from complaining about it. Constantly. Who the fuck did he think he was, getting that big? Standing next to Bakugou and making him look like he was, horrifically, below-fucking-average.
He’d outgrown even Satou and Shouji to become the biggest out of their graduating class. And not just in size, obviously, but in popularity because Kirishima was a fucking incredible hero.
At first, the rest of their class didn’t seem to realize what had happened, because they all were grossly codependent and saw each other regularly, and shit like that when seen everyday seemed so gradual and unnoticeable to these morons.
It took just one moment of fucking Denki craning his neck up at Kirishima after having a few cocktails at their quarterly, mandatory night out, and letting out a stunned “whoa…” for the rest of the idiots to clue in.
After that… chaos.
The girls, even Tsuyu who was so, so painfully a lesbian, were all over him. And most of them not even sexually because living in the dorms with all the guys, sharing living space and a kitchen and toilets and a gym, for three years had really worn out the novelty and potential sexual attraction for most of them. Mina was the only one that made Bakugou want to growl angrily, but they were, whatever, friends and Bakugou maybe liked her enough to not feel…
Well, to not feel fucking jealous, is what it was.
Aoyama and Todoroki also seemed to get a little too fucking friendly with him. Even goddamn Shinsou.
And worst of fucking all… fucking Deku, who everyone had thought had grown out of his stupid blushing and mumbling phase, got tongue-tied around Kirishima sometimes.
Kirishima though…
Well, he was Kirishima about it. Fucking oblivious.
He was careful in public, but when they were in their apartment, Bakugou really got to witness the full extent of it. The dumbass even still moved like he thought he was half his size, constantly knocking into things and really testing the structural integrity of the cheapass furniture they had bought after graduation, and had yet to replace.
He seemed baffled when he would try on old sweats or t-shirts that almost immediately ripped along the seams. Was fucking devastated when he ruined one of his worn out Crimson Riot tees, actual goddamn tears filling his eyes.
Bakugou had really lost all self-control at that point and grunted at him as he retrieved the shirt with an offer to mend it.
Which he did.
And then never gave back, because, well… it wasn’t really gonna fit Kirishima anymore, but it fit Bakugou just fine.
He’d thought he was being sneaky about it, until he realized weeks later that Kirishima had never asked for it back. And had certainly seen it smushed under one of Bakugou’s pillows when he’d flopped onto the bed to complain to Bakugou about the konbini being out of his favorite bento for lunch that day.
So… not very subtle then.
What ended up sending Bakugou over the edge, well… fucking anyone else would have lost it too.
They’d both been working separate villain attacks for their respective agencies, and eventually someone higher up had rubbed a few braincells together and figured out that the attacks were connected.
What they’d thought was a few related cases of insurance fraud by-way-of arson and property destruction ended up being a fucking clusterfuck. They’d tracked down the guy who’d hired all the dumbasses they’d already caught and walked into the middle of a goddamned human trafficking ring.
Bakugou hated this shit. There was nothing he could Howitzer that would change the trauma these people, fucking children included, had gone through.
He’d jumped into action quick enough, taking on some of the more dangerous-looking quirks in the room from the fucking minions or whatever that guarded the shipping crates full of actual human beings and God, Bakugou wished he could just leave them as bloody smears on the concrete floor of the warehouse. They were with a team of about eight other heroes so the room was loud and hectic and Bakugou lost track of Kirishima pretty quickly.
Until the noise started to die down, heroes busy cuffing up the unconscious bodies of these assholes.
Until Bakugou watched as Kirishima, tangling with the ringleader who had some sort of strength-based quirk as well, had palmed the back of man’s head in one huge hand as he stepped around him and single-handedly lifted the guy and slammed him face-first into the ground.
It would be completely fucking inappropriate to be turned on at a crime scene.
Completely.
Bakugou blew out a long breath as he figured that was it, that Kirishima would now just cuff the guy and leave it at that.
That was not it.
Kirishima stood back up from his crouch, lifting the man with him, dangling the asshole’s feet completely off the ground. The bad guy’s face was fucked, nose broken and teeth missing, his struggling minimal as he clearly just tried to gasp through the damage. Bakugou watched as Kirishima dragged the guy’s ear towards his own face, whispering something lowly once he was close.
The man, clearly possessing more balls than brains, hissed something back as he spat out blood.
Bakugou’d never seen Kirishima look so furious.
He slammed the man back into the ground feet-first, and the sound of both his ankles snapping was loud enough to be heard over the rest of noise in the room. Kirishima continued pushing him down until his knees hit concrete with a similarly loud crack. Let go of the man’s head as he collapsed, passed out from the pain.
The other heroes were staring at Kirishima in varying levels of shock.
Bakugou was ready to climb him like a fucking tree.
Kirishima’s eyes met his, and well, it was all fucking over then.
--
Ten months later, and they were here.
Bakugou leans against the doorframe naked, keeps his posture as lazy and relaxed as he can while his eyes were fucking devouring the sight of Kirishima, patiently sprawled out on his back on the bed. Arms already above his head on the pillows, crossed at the wrist. Even in their lax state, his biceps and delts still bulged out of his arms enough that they brushed the sides and top of his head.
His broad chest, solid pecs, sparsely dusted with dark hair, framed by his resting lats being pushed out by his own weight. Dimples around his abs, not sharply cut like they were when they were both teenagers, now softened slightly by the bit of fat he carried on him these days. Making him look extra fucking solid and sturdy.
A trail of dark hair that thickened as it grew closer towards the base of his cock. His waist wasn’t snatched like Bakugou’s, instead nearly as wide as the rest of his torso. A width that regularly tested the flexibility of Bakugou’s own hips.
One leg comfortably straight, cock laying thick and flushed against his massive thigh, while the other was bent slightly, hip cocked open and his knee resting against the wall their bedframe was pushed against. His eyes are closed, his face relaxed and smooth, breathing even and slow.
Completely at peace, while waiting on Bakugou. So fucking perfect.
He resists touching his own filled-out cock, knowing it’ll get plenty of attention soon enough.
“How long you gonna make me wait, Katsuki?”
Bakugou’s gaze jumps back up to Kirishima’s face. His eyes are still shut, but the corners of his mouth tilt up in a very fucking inviting grin, one sharp tooth poking out over his bottom lip.
“As long as I fucking want.”
But he’s already pushed off the doorframe, padding over to the bed softly in his bare feet.
Kirishima’s got a good pokerface, but his cock jumps eagerly against his thigh as he hears Bakugou approach.
Bakugou plants both of his hands on the mattress next to his man’s head, leans over to bite at the curve of his chin, startling a breath out of him. Nudges his chin back so he can get his teeth just below the man’s adam’s apple, biting down a little more firmly.
Kirishima’s so fucking easy like this, so pliable, as he lets Bakugou suck a mark onto his throat. He’s so fucking good too, hasn’t even tried to move his arms or legs, even with Bakugou so close.
Bakugou can feel the bigger man’s throat contract as he swallows, can taste the faint salt of his skin. He removes his teeth and rests his forehead against Kirishima’s tricep as he takes a bracing breath.
“Wrists first.”
He tears himself away as he speaks, trailing a hand up Kirishima’s right arm as he reaches for the cuffs already looped around one of the slats in the headboard. He brushes his thumb firmly against the vulnerable inside of Kirishima’s wrist before closing the leather strap around it and buckling it carefully. He slips his index finger between the cuff and Kirishima’s skin to quickly test the tightness, and feels the man’s fingers brush the back of his hand as he reflexively closes his fist. Bakugou can’t help the fucking fond smile he feels tugging at his own lips. Kirishima makes him so disgustingly sappy.
He quickly binds Kirishima’s left wrist as well and straightens up.
“Tug.”
Kirishima obediently pulls on the restraints, using barely a quarter of his strength. Bakugou rolls his eyes in irritation.
“Tug for real, asshole.”
Kirishima huffs out a laugh and this time, Bakugou can see the strain along his beautiful fucking arms as he yanks on the cuffs, headboard creaking dangerously.
Damn, this is already the third bedframe they’re on, and they’ve only had this one for three months. Kirishima should really get a side gig at stress-testing supposedly quirkproof furniture.
Bakugou pushes his cock into the side of the bed, eyes fluttering a little at all the power he’s just contained in two flimsy leather cuffs. Bites back a soft moan, but not quickly enough to stifle it. He looks down as Kirshima’s eyes snap open, pupils dilating sharply. Bakugou sees his eyebrows scrunch down as he bares his teeth slightly. The other man searches his face for something, and Bakugou humors him for a few seconds. But only a few seconds.
“Eyes closed.”
Bakugou watches until Kirishima blinks twice and then lets his eyelids slide shut. He pushes himself away from the mattress, feels some of his sticky precum drip down the inside of his thigh as his own cock bounced against it. He moves down towards Kirishima’s legs, letting his fingers graze the thick muscle of his quad right below where his flushed cock rests. There’s a constant stream of pre pouring out of Kirishima’s cock, running down the side of his leg to pool onto the mattress. Kirishima flinches at Bakugou’s touch, and Bakugou feels his muscles tense as he resists pushing back into the sensation.
“Ankles too.”
Kirishima doesn’t bother to bite back his groan at that, immediately extends his other leg out as Bakugou strides to the end of the mattress to gather up the ankle cuffs hanging off the footboard.
Bakugou grips both of his ankles, yanking them to where he wanted them and goes through the same careful steps he took to bind his wrists. He unclips the carabiners from both ends of the chain and doubles the length down so that Kirishima’s legs are pulled straight except for a slight bend in the knee.
Bakugou’s hands are sweaty, dangerous, by the time he finishes. He grabs the towel they keep slung over the footboard to wipe them down as he finally allows himself to drink in the picture he’s created.
It’s lassoing a hurricane, building a barrier out of goddamn chopsticks to stop a landslide. Fucking laughable, to think all that raw strength, the sheer size of him could be contained by a few strips of leather and bits of steel.
And in reality, it can’t be. Kirishima could tear through the restraints like they were fucking tissue paper if he wanted to. With a simple flex of his densely muscled back and arms, and the barest application of his quirk, Kirishima could tear out of his restraints, force Bakugou facedown on the mattress and plow into him with every ounce of force he could create.
But he doesn’t. He doesn’t because that’s not what Bakugou wants.
And Kirishima will give Bakugou anything he wants.
“Open.”
Kirishima’s eyes blink open again, slowly this time, searching until he finds Bakugou next to the bed. Smirks and winks as he opens his mouth too, letting his tongue hang out, covering his viciously sharp teeth.
Bakugou’s on the bed in an instant, knees bouncing on either side of Kirishima’s hips as he straddles him. One hand grabs a fistful of his red hair while the other grabs his tongue. Bakugou gets in his face, baring his own teeth as he carefully squeezes down.
“You want something? With your mouth open like that, I’m taking it as a fucking invitation, Eiji.”
Bakugou pushes two of his fingers into Kirishima’s mouth, pressing down on his tongue and massaging, carefully avoiding his upper row of teeth. Kirishima moans shamelessly, but doesn’t try to suck on his fingers. Won’t, until Bakugou tells him too.
Bakugou traces the inside curve of Kirishima’s bottom row of teeth, slides his fingers through the mess of saliva gathering under Kirishima’s tongue. He strokes along the insides of his cheeks, the roof of his mouth, watching Kirishima’s face closely. He can feel the man’s lower jaw start to tremble from the strain of keeping it open.
“Suck.”
Kirishima’s tongue eagerly slides along the bottoms of Bakugou’s fingers, wrapping around the tips and flicking into the small space separating the two of them. There’s spit dripping down his chin as he does, and Bakugou can see the faintest sheen of sweat starting to gather around his collarbones.
Without a word, Bakugou pulls his hand back, the other still fisted in Kirishima’s hair pulls his head back further.
“Wanna taste something else?”
Kirishima licks at his lips obscenely.
“Of course, baby, you can- “
Bakugou slaps him. Not too hard, but neither of them are exactly the type to go easy on each other.
“Rhetorical fucking question. If I want you to fucking speak, I’ll tell you.”
Kirishima barely looks phased by the slap, other than the narrowing of his eyes as he lets Bakugou push his head back into the pillow.
Kirishima forces a grin at him, showing every single one of his bright, shiny teeth. But Bakugou knows he’s feeling far less than smug as the clinking of chains being pulled taut reaches his ears.
Strands of Kirishima’s hair stick to the thin layer of sweat on his arms as he pulls against the wrist restraints.
Fuck, Bakugou loves this. Feels the burn of arousal heat his stomach and his inner thighs as he thinks about how fucking much he knows Kirishima wants him. God, he just wants to jerk off all over Kirishima’s face right the fuck now. And he fucking would, if he didn’t love edging himself so goddamn much.
On the other hand, it’s not like he’s a one-and-done kinda guy…
The pinch in his balls as he pictures Kirishima’s handsome, sharp face splattered with his cum makes the decision for him.
He pushes Kirishima’s head back into the pillow aggressively one more time and the plants both hands on the bed and he leans into them, swinging his hips underneath him to sit on Kirishima’s wide chest.
Kirishima’s eyes light up as he realizes what Bakugou’s planning and wiggles his eyebrows at him. Bakugou can’t stop the grudging laugh that provokes out of him and he pokes Kirishima lightly in the ribs. He feels the man’s entire body shudder as he squirms to avoid the touch. Unfairly fucking cute, the ticklish bastard.
Bakugou reaches over Kirishima’s head to plant his left hand between Kirishima’s own. Kirishima knowingly locks both his big, callused hands around Bakugou’s wrist and forearm, to help keep him steady. Bakugou pushes up on his knees to dangle his cock directly over Kirishima’s face, cupping his own balls as he sighs in relief at his own touch. Precum splatters across Kirishima’s cheek as he starts to stroke down his cock, squeezing the tip to push out even more. Kirishima arches his neck, tries to tilt his head to catch some in his mouth, but Bakugou denies him, sitting back.
“You’ll take what I fucking give you. And if you don’t move again, maybe I’ll give you something you want.”
For a moment, Bakugou’s sure Kirishima’s not gonna listen. But despite looking like he wants to tear free and swallow Bakugou whole, Kirishima takes a ragged breath and nods tightly.
Kirishima’s really got everyone else fucking fooled. People go around talking about how he’s a fucking saint, always so friendly and patient and all this other bullshit. But they’ve never seen him panting, desperate for them.
And they fucking never will, if Bakugou has anything to fucking say about it.
He leans back over Kirishima’s face and gets down to goddamn business, having stupidly aroused his own jealousy over his own fucking imagination.
Within a few strokes, Bakugou’s only thinking about making himself cum. He watches as Kirishima’s face reddens, as he constantly licks his lips and his gaze bounces from Bakugou’s dick to his face.
Oh shit, this is gonna take way less than Bakugou thought.
Bakugou changes it up from stroking up and down to fucking his fist instead, hips pumping furiously into his own wet hand, the slick sound of it growing louder as he gets closer and closer to orgasm. He hears the deep, desperate rumble in Kirishima’s chest, the sound of the footboard creaking as Kirishima tries to get his legs under himself to thrust his own cock uselessly into the air… and that’s it.
Bakugou barely has the presence of mind to aim as he cums, shooting messily across Kirishima’s nose and upper lip.
“Fuck! Eiji-shit!”
“That’s it baby, c’mon, fuckin’ soak me with it-”
Bakugou whines as his balls clench again and he jerks out a final stream of cum across Kirishima’s bottom lip, slumping slightly forward as he catches his breath. Won’t even punish him for speaking because fuck, he needed that.
He pries his eyes open from where they’ve squeezed shut and watches as Kirishima licks up all the cum his tongue can reach, looking satisfied as hell.
It’s even fucking better than Bakugou’d pictured it.
He’d managed to avoid cumming right in Kirishima’s eyes, thankfully, and they both smirk at each other as their eyes meet. The other man shifts beneath him, restless, muscles flexing and shifting as he tries to find some position that provides him even the barest hint of his own pleasure. But he won’t be able to find it. Bakugou wipes his hand off on the blanket next to Kirishima’s face, and wipes the sweat off his own forehead with the back of his hand, some of it splashing onto the man below him.
Kirishima’s worked up enough of sweat that Bakugou can faintly smell his scent now, and there’s just something about the fact that he’s barely even touched the man but got him gagging for it that really just fucking does it for him.
The bigger man beneath him looks torn between a faint impatience, and the desire to let Bakugou have control. But nothing on this earth can keep Kirishima silent for long. Bakugou would know, they’ve wasted plenty of money on gags that Kirishima’s teeth had torn straight through in seconds.
“Gonna give me something good, Katsuki?”
Alright, Kirishima’s already bounced into territory too close to smug for Bakugou’s liking. He tugs at the wrist Kirishima has in his bone-creaking hold and for a moment, Kirishima doesn’t let go. Bakugou lets his hand pop warningly and Kirishima’s fingers slowly peel off. Very slowly.
Bakugou stares down at him, making Kirishima wait.
Then he grins evilly as he plants both hands back on either side of Kirishima’s head and leans over to smother the man with his chest, feels the tip of Kirishima’s nose catch the bottom curve of his left pec.
The fervent “fuck!” Kirishima lets out is muffled against Bakugou’s chest as he rubs the soft skin of his right pec through his own cum on Kirishima’s cheek.
The man never shuts the fuck up about Bakugou’s chest, he should be fucking grateful for this.
Kirishima’s lightning fast, and within moments has a chunk of plush, muscled pec between his teeth, leaving careful impressions while he sucks hungrily at it, leaving an obnoxiously big, dark mark. Bakugou’s not mad about it though, it feels fucking amazing.
He grabs Kirishima’s chin with one hand as he directs his mouth to his nipple, moaning in deep satisfaction as Kirishima takes it gently between his teeth before sucking it into his mouth, lips rubbing the skin around it as his tongue flicks across it. God, that’s the good shit.
Bakugou feels the faintest scrape of teeth as Kirishima bites down and pushes his sticky, half-hard cock against the bigger man’s abs. He’s barely even fucking gone soft but goddamn he loves Kirishima’s teeth against him.
Bakugou yanks his mouth off and lets him slobber across the deep, sweaty crease between his pecs, before pushing it back down to spend some attention on the other nipple.
Kirishima’s cooing, making pleased noises, like he doesn’t even hear himself, can’t physically hold them back, as he bites and sucks a bruise directly into the already blood-flush skin. When Bakugou feels his dick start to chub up properly again, he sits back, rubbing it lightly against Kirishima’s stomach as he looks down at his blissed out face. Kirishima strains his neck as far as he can get it off the mattress, tugging at the cuffs around his wrists, as he tries to chase Bakugou’s body eagerly.
“Baby, let me suck your tits some more, c’mon, please, I’ve been so good…”
Shit, Bakugou loves the sound of his begging. He lets him talk, clenches his knees on Kirishima’s ribcage as the man manages to dig his heels into the mattress and push up against Bakugou, lifting them both a few inches off the bed. He thrusts up helplessly as he pleads, then drops his hips back down in defeat. Bakugou keeps his perch, more than used to riding out Kirishima’s strength.
“Please, Katsuki, please, fucking- let me- give me anything, please, fuck I need you so bad. Let me fuck you baby, I wanna make it so good, be so good to you, just, please!”
The chains on the cuffs creak ominously again, along with the bedframe.
Bakugou kneels all the way upright, taking his weight off Kirishima, and slaps roughly twice at the upper ridge of the man’s abs.
“Fucking stay still. God, you’re fucking shameless aren’t you? You’ll say anything to have me, won’t you? You’ll do anything I tell you, and you’ll fucking love it.”
Kirishima’s hardening ripples up his arms, probably down his legs as well where Bakugou can’t see. Bakugou stays silent as he watches him struggle to get his quirk under control. Kirishima knows the rules. He’ll either rein it in, or he’ll get nothing.
Kirishima’s whole body shudders with effort, every muscle tensing, flexing on his enormous frame as he breathes heavily, thrashing wildly against the restraints. Bakugou is tensed, hands popping as his adrenaline surges, watching this man nearly come undone from sheer fucking want alone.
Slowly, with a massive fucking effort on his part, Kirishima’s body settles from an earthquake to mild tremors as he gasps for breath, covered in sweat like he’d just fought half a dozen villains. And honestly, not even villains could give him a run for his money the way needing Bakugou does. He blinks dazedly up at Bakugou, turning quickly to wipe the sweat off his brow onto his right arm, shaking his head to try and shift his hair off his face. Bakugou reaches down to brush it back for him, tucking strands behind each ear, tracing the curve of one with his index finger just to watch Kirishima tremble again. Wipes away some of the drying cum on his nose that somehow hadn’t been rubbed into his own chest.
“Katsuki…”
Bakugou can barely handle it, fuck. He leans down urgently to kiss Kirishima, pushing his tongue past his lips with his trademark recklessness. He nicks his tongue regularly and it’s never stopped him before. Never will fucking stop him. Kirishima’s a little more careful, keeping his teeth mostly covered as he sucks on Bakugou’s tongue greedily, stopping every few moments to pant and catch his breath. Bakugou licks across his plush bottom lip and bites at it a few times, bruising it, and then chases a line of drool down his chin.
Bakugou trails a series of kisses down his neck, along his trap, down to his shoulder, peeking downwards between his own legs to Kirishima’s thick, agonizingly purpled dick. Oh, he’d better take care of that.
“Eiji, fuck you did so good. So good. I’m gonna- gonna let you come now.”
Kirishima hisses out a breath, hips lifting slightly again.
“But you’re gonna get yourself hard again while you eat me out. I’m gonna fuck myself on your face, and then I’m gonna take your thick, fat cock and ride it until you’re begging me to stop.”
The whine that strangles out of Kirishima’s throat is inhuman, and quick to drop into a savage, threatening growl.
Bakugou peels his forehead off the dip of Kirishima’s shoulder to sneer at him before he slowly pushes himself down his body, hips splayed almost uncomfortably wide as he tries to walk his knees backwards while sliding himself down. God, he’s just so fucking big.
They’re both sweaty as fuck now, nearly no friction as Bakugou’s inner thigh bumps against the tip of Kirishima’s cock, and the bigger man makes a noise so desperate that Bakugou’s certain he’s about to cum. He watches Kirishima clench his eyes shut, bite a bloody gash into his bottom lip as he resists. Fuck, and his control is fucking immaculate.
Bakugou reaches down to guide Kirishima’s cock into the divot of his hip as he continues moving backwards, pausing to rock up and down against it a few times. The amount of precum smearing across his hip is fucking obscene, just like the whimpers Kirishima’s biting back.
Bakugou continues, making sure every ridge of his own abs rub against the tip of Kirishima’s dick as he moves, digging his fingers into Kirishima’s sides as he starts pushing off the bed again, thrusting violently up into Bakugou.
It’s when Bakugou finally lets the man’s cock slide between his pecs that Kirishima loses it. He manages to get one ankle over one of Bakugou’s calves to hold him in place and fucks his hips up so roughly that for a second Bakugou’s goddamn sure that he’s going to take the entire bed with him.
It takes four quick, powerful snaps of his hips and Kirishima cums, head snapping back to dig into the pillows as he shoots rope after rope of thick, sticky white cum across Bakugou’s chest all the way up to his chin. His mouth is cracked wide open but not a sound comes out as his back arches painfully for the final few spurts of cum.
When Kirishima goes limp, he manages to unseat Bakugou, who can’t get a good grip with his palms against his sweat-slicked skin.
Kirishima’s massive chest expands and contracts rapidly, entire torso like a fucking sculpture as he tries to catch his breath. Bakugou assumes he’d be at least a little sated, but the glare the man angles down at him next is anything but. Kirishima looks like he’s goddamned starving.
Bakugou’s own cock is hanging heavily between his legs as he unwinds him from the hold Kirishima got him in. He doesn’t give into the temptation of humping the mattress like a fucking dog, he knows what he wants and he’s gonna do what he needs to get it.
Kirishima swallows heavily a few times, licking at the blood dripping off his lip. His hair is clinging to his face messily again, and with what Bakugou’s about to do, it’s just become a fucking hassle now. He rolls off Kirishima to the side for a moment and climbs shakily up the bed until he can reach one of his cuffed wrists, sliding off a hair tie he knows the man always has on him. He gently collects every strand of Kirishima’s hair, the man helping him by lifting his neck slightly, and threads it through the hair tie twice, leaving it in a pile on the top of Kirishima’s head.
Kirishima tilts his head to the side to kiss at the only part of Bakugou’s forearm he can reach in a quick thanks.
He smiles up at him, still partially blissed out.
“Come sit on my face, baby.”
Bakugou smirks back at him and swings a leg over across his head and restrained arms. He’s not fucking afraid of crushing Kirishima, and sits down heavily, humming as he feels Kirishima’s tongue slide up across his taint to his hole, slick, strong and eager.
He leans forward slightly to plant his hands on Kirishima’s pecs, massaging the muscle there gently at first, and then more insistently, plucking at his brown nipples teasingly.
Fuck, the fucking sounds… Kirishima really has no fucking shame as he spits onto Bakugou’s hole and then pushes it in with his tongue. He eases it in just a few centimeters, flicks at the fluttering rim a few times and then plunges it in as deep as he can reach, sucking and slobbering against the tight circle of flesh. His mouth is half-opened as he does it, and Bakugou can hear every breath, every sigh, every slick squelch as he devours Bakugou’s ass like it’s the only thing he wants in life.
Bakugou’s legs start to tremble as he pushes his hips back, rides Kirishima’s tongue like it’s his cock. He can hear the frantic rattling of the chains as Kirishima tugs at them, fighting to get a palmful of Bakugou’s ass and squeeze for all he’s worth. Bakugou fists his own cock, strokes a few times but pulls back at the first clench of his balls. Wants this second round to last.
Fucking reluctantly, Bakugou pulls away, his twitching hole and inner thighs soaked with Kirishima’s spit. He feels heat race down his spine as he thinks about how he must fucking look dripping with both of their sweat, cum, and saliva all over his body. Kirishima leaves him a fucking mess everytime, and he fucking loves it.
“Done already? C’mon Katsuki, show me that wet, clenching pussy of yours.”
Bakugou whips his head around to look over his shoulder angrily as he shivers.
“I fucking told you not to call it that. It’s my asshole, dumbass.”
Kirishima’s face is a mess, but he smiles, missing innocent by a mile, up at Bakugou.
“Baby, I know you love it. Can’t fool me, you love it when I tell you how much I like fucking this wet. Hungry. Pussy.”
Bakugou’s hips roll back a bit at the sound of Kirishima’s voice before he can stop himself. Kirishima laughs victoriously, the fucking shithead. Bakugou turns away, trying to steady his shaking legs enough to reposition himself when he feels and hears Kirishima spit on ass with disgusting accuracy, the hot gob of it sliding into his crack. Bakugou’s vision goes white around the edges for a moment, just a second, but fuck why is that so fucking hot?
His legs wobble and fold and he tips forward to land on Kirishima’s stomach as he curses, his cock crushed awkwardly between their bodies.
“Mm, baby that’s a nice view. I could eat you out some more if you want, stretch out that tight hole with my tongue ‘til you’re sobbing-”
“You fucking wish. I’m gonna make you cum so hard you black out. Make you feel so good you’ll think I literally fucked your brains out.”
His hands slide a little as he pushes himself up, rolls off Kirishima to glare up at him. Kirishima shrugs, chains rattling.
“Do your worst, baby.”
Bakugou doesn’t trust his legs enough to stand up, so he crawls down the bed towards their dresser to grab the bottle of lube they left there yesterday. Fuck, he feels so fucking wet down there as he angrily tears the lid off and sits between Kirishima’s spread legs. From this angle, everything about Kirishima seems even more massive, from his thick legs to his cock to the long stretch of his torso. Christ, it’s a miracle he even fits in this fucking bed.
Bakugou dumps a messy handful of lube into his palm and walks up the bed on his knees, using them to push Kirishima’s legs as far apart as the ankle cuffs will allow. Kirishima is watching him expectantly, eyes heavily lidded as he reaches for that monster cock and coats it with a probably unnecessary amount of lube. He wants to torture Kirishima a little more, really draw it out and jerk him off till he’s right at the brink. But more than that, he wants to ride that dick for fucking hours and if Kirishima’s on a hair trigger, well, it’ll be over far too soon. He reaches back with the slick remainder of lube on his hand and smears it across his own asshole, pushing it in carelessly with the tips of his fingers.
That’s about all he has the fucking patience for.
He locks eyes with Kirishima.
“Don’t you dare fucking cum ‘til I tell you to.”
“Whatever you want, Katsuki.”
“I fucking mean it. You’re gonna fuck me until I can’t feel my legs or I’m gonna leave and find someone who can.”
He doesn’t mean it. He never means it. But it’s always fucking worth it to see Kirishima lunge for him, even though the motion is basically useless when he’s restrained like this.
“Won’t. You won’t Katsuki, don’t play with me. You’d never even think about it.”
Katsuki hums, drops Kirishima’s cock so it splats wetly against his stomach and slings one leg off the side of the bed. He’s never tried taking it this far, but…
The metal slat the wrist cuffs are chained around bends in half with a screech as Kirishima pulls at it sharply, his quirk rippling around his wrists. Not broken yet, but held by a fucking prayer.
Bakugou pulls his leg back onto the bed and digs his fingernails into the upper part of Kirishima’s quad.
“You’re right, Eiji, I wouldn’t. Because I deserve this big fucking cock, your big fucking body, and I deserve you. And no one else does. Because you’re mine. Do a good job reminding me of that and I may even let you off-leash.”
Kirishima still looks pissed that he even pretended to leave but he forces out a long exhale and his quirk slides back under his skin.
“Like I said, ‘whatever you want, Katsuki.’”
Bakugou straddles his waist and leans over him to pat his cheek patronizingly.
“Good boy.”
And fuck, he’s made himself wait long enough for this.
Bakugou reaches behind himself to grip Kirishima’s cock firmly around the base, sitting back slowly, gaze glued to Kirishima’s face as the man watches the tip of his cock press lightly against Bakugou’s taint. The fucking look on his face… Bakugou can wait a bit longer if he gets to see this primal hunger jagged across Kirishima’s face. He tilts his hips so the cock skids wetly along his skin to bump up against his balls, already drawn up tight just from the anticipation of getting split open on Kirishima’s cock.
Kirishima groans in disbelief that Bakugou is still toying with him, the bent metal slat creaking dangerously as he flexes unconsciously against the restraints. Bakugou slides his hand up to grip just under the head of his cock and rubs it harder against his balls, getting wetter by the second as Kirishima’s precum fountains against the wrinkled skin. He squeezes his thighs together just to feel the slick sensation, and Kirishima makes a sound like he’s been mortally fucking wounded as his cock thrusts between Bakugou’s own thick muscle.
“Fuck, Katsuki, you’re fucking killing me here baby, please just, please, sit on my fucking cock or put me out of my fucking misery!”
Kirishima only curses that much when he’s at his breaking point. Bakugou relents.
He reaches his other hand around to pull his asscheek out of the way as he guides the head of Kirishima’s cock against his hole. He’d barely got them aligned before Kirishima bucks upwards, the first three inches of his cock shoving into Bakugou’s hole roughly.
It’s hard to tell which “fuck!” is louder as they both scream it out into the goddamn filthy, humid air of the room.
Bakugou feels Kirishima draw his hips back to push in deeper and forces himself to sit up more so the next thrust is still frustratingly shallow.
“Katsuki, I swear if you don’t fucking-”
“You’ll what, Eiji? You’ll fucking what? I’m fucking you right now, and I’ll take as much of your cock as I want, when I want. Now sit the fuck down.”
Kirishima growls fucking ferociously, eyes dilated so wide there’s barely any red left in them. Before the man can stage any further resistance, Bakugou impales himself all the way down his cock, ass smacking into his hips hard enough he could swear it fucking echoes.
Kirishima howls in victory as Bakugou grinds down onto him roughly. He bounces himself a few times, letting just a few inches slide out before sinking back down to the base, eyes shut in pure bliss as he feels that fat fucking cock carve its way deep into his guts. Fuck, there’s no better goddamned feeling in the world than being split open and filled so thoroughly he can barely fucking breathe.
Bakugou feels a fire race down his spine as his hands spark, and suddenly he’s right on the edge of cumming. Too fast, too fucking fast…
He fists the base of Kirishima’s cock again as he pulls completely off, sweat dripping into his eyes as he hovers over Kirishima’s body.
There’s a noise that rumbles so low out of Kirishima’s chest that it practically vibrates through Bakugou’s body, and then the sound of the metal slat of their headboard giving way as Kirishima rips the chain clean through it.
The bigger man is sitting up and wrapping his hands around Bakugou’s waist before he can stop him, chains roughly scraping across their thighs between them. His hands clench so tightly into Bakugou’s skin he knows without a fucking doubt there’ll be bruises there tomorrow.
And then Kirishima stops moving. He searches Bakugou’s surprised gaze. Waits for Bakugou to make the next move.
Fuck, Kirishima’s so good for him.
Bakugou reaches his free hand down to grab the slack of the chain and pulls it taut in his fist before sinking back down onto Kirishima’s cock slowly. One-inch-at-a-fucking-time, slowly.
Kirishima leans in, mouth mere millimeters from Bakugou’s as his breath puffs against his lips hotly.
Waiting, again, for Bakugou to make the next move.
Sitting up with his ankles still restrained, Kirishima’s thrown away all of his leverage for the moment. Bakugou sinks all the way back down that thick cock, everything feeling like a slick and easy slide from the sheer amount of fluids they’re both drenched with. As he bottoms out, he catches Kirishima’s mouth with his own and kisses him, lips smashing together with zero coordination until Kirishima fits them together and licks his way into Bakugou’s mouth, running his tongue across every surface it reaches while Bakugou moans around it.
Kirishima tears his mouth away and dives for Bakugou’s neck, making small moans and whimpers as he sets his teeth against the pale skin there over and over, each prick of them a sensation that’s directly fucking connected to Bakugou’s cock. He fucks himself roughly on Kirishima, regripping the chains in his one hand as they get harder to hold as he sweats all over them, planting the other hand on Kirishima’s hip, using the wide expanse of muscle to balance himself.
Kirishima’s barely managing small thrusts of his own, still unable to get his legs under himself for any ounce of support. One stroke strikes lucky as the tip of his cock glances off Bakugou’s prostate, making Bakugou clench down tightly around him, breath stuttering out of him.
Bakugou can feel the edge approaching, again, so close, so fucking close…
But not fucking yet. He’s not done with Kirishima yet.
He slings his legs around Kirishima’s waist quickly, hip flexors groaning in protest at the position, and locks them, stopping Kirishima from moving at all.
The bigger man makes a protesting groan against the mouthful of skin he has.
“Katsuki, God, fuck, what do you want from me? Baby, please!”
Bakugou gives himself a moment to come down a little. Lifts the hand holding the chains to push at Kirishima’s head until he leans back.
“Not gonna stop this time, Eiji. This time, I’m gonna use this cock until I cum.”
Kirishima licks his lips, nods in agreement without hesitation.
“And then, uh-fuck-, then you can take what you want from me. However you want. And you’re gonna cum inside me, leave me fucking filthy with it.”
Kirishima’s speechless, nodding like he can’t believe what he’s hearing. And fair, Bakugou almost never lets him do this. But Bakugou’s done a lot of the work tonight, and now he wants his own reward.
He lets go of the chains momentarily to push at Kirishima’s shoulders until the man drops backwards, propping himself up on his forearms. The chains look fucking hot draped across his stomach as he shifts down the bed an inch to get just the tiniest bit of leverage.
Satisfied, Bakugou starts to work himself up and down Kirishima’s cock again, riding up and down a few inches at first, unwilling to feel less full than when that fat dick is spreading him open so fucking good, but working himself up to longer strokes because he loves when the spongy tip of Kirishima’s dick nails his prostate as he pushes back in.
Kirishima watches him, watches him like there isn’t a single thing in this world or on any other that could tear his gaze away.
Bakugou’s legs start to cramp up, start to tire from a long day of hero work before this, and he whines in annoyance as he chases after his orgasm, fucking determined to cum this time, to stop edging himself to the brink of fucking insanity.
Kirishima knows, always knows, always so fucking good, and rocks his hips up off the bed to keep Bakugou’s rhythm. And then, his fucking mouth.
“Look at you baby, look at you taking me so deep, so good. Fuck, you can have all of me, you do have all of me, anything you fucking need, Katsuki, I’m gonna give it to you, let me keep you full, keep that pussy so fucking full, so happy-”
Bakugou’s breath stutters, whining loudly as he reaches for his cock, getting barely a few strokes in before Kirishima fucks deep, so deep that Bakugou’s cumming all over the both of them, eyes rolling back into his head as his back arches and he tips backwards.
And he keeps tipping backwards, he’s not fucking sure how he’s dropping so much, he’s still fucking cumming, and then his back hits the mattress the same time he hears the chain holding Kirishima’s legs down snap with a loud, metallic ping. And Kirishima keeps pushing him, keeps shoving him back until only Bakugou’s shoulders are touching the bed, roughly tearing one of his legs off Kirishima’s waist and pushing it over his shoulder as he fucks straight downward into Bakugou’s hole, still fluttering and clenching from his own orgasm.
Bakugou chokes on his next breath as Kirishima slams into him, hips smashing against his asscheeks loudly, fucking brutally as he hammers into him. Bakugou’s vision is too blurry, he can’t see properly as he veers into nearly painful overstimulation, but fuck Kirishima has never felt more enormous, more like the force of fucking nature that he is, like a beast fucking savaging Bakugou’s body, relentless, powerful, and god, how fucking lucky is Bakugou that this goddamn perfect man submits to him when he could just fucking crush him with a single finger if he wanted to-
Kirishima nearly folds Bakugou in half as he cums, rutting and grinding his hips as his load shoots hot and deep into Bakugou, his bodyweight forcing his cock just that much deeper and Bakugou can’t breathe, he’s moaning and sobbing like he can’t fucking take it-
And then Kirishima’s weight disappears as he rocks backwards, somehow managing to keep his cock sunk within Bakugou as he lifts him, sliding his leg off his shoulder and bringing him along until Kirishima has fully collapsed back onto the bed, sprawling Bakugou’s limp form across his broad, wide, fucking perfect body, chain connecting the wrist cuffs sandwiched between their chests.
Neither of them have even an ounce of energy to even speak. They lay there, panting like racehorses, for what must be actual minutes.
Bakugou feels Kirishima’s chest shudder beneath him and he looks up with the most concern he can muster at the moment, which admittedly is a pitiful amount.
Kirishima is laughing. Full-on giggling soundlessly, until he gets enough air back in his lungs to produce actual sound. Hearing it makes Bakugou burst into uncontrollable laughter as well, until they’re both laughing like idiots, probably slowly being cemented together by dried cum and sweat and lube.
“Goddamn, Katsuki. Just… goddamn.”
Bakugou snorts unattractively as he tries to get a hold of himself, regaining enough strength to prop himself up on Kirishima’s chest.
“Don’t laugh, asshole, you were the one begging like a little bitch like five fucking minutes ago.”
Kirishima squeaks loudly as his laughter ramps up again.
“Awww, baby, you know I don’t mind being your bitch. Fuck, as long as we keep having sex like that, you can literally call me whatever you want.”
Bakugou smacks at his face, lacking any semblance of coordination, as his hands pop in small explosions, completely harmless at this point.
Can’t fucking argue with that though.
“Mmm, always surprised you can move your giant Mount Everest of a body that well. Did a pretty fucking outstanding job of drilling me at the end though.”
Kirishima huffs a few quieter chuckles and reaches up to brush Bakugou’s sweaty bangs out of his face.
“I know you only love me for my body, Katsuki. And my dick.”
Bakugou shrugs in agreement, but when he knows Kirishima is gazing down at him with, God, with fucking devotion in his eyes, he leans up to press a secret, swift kiss right over his heart.
