Work Text:
A glittery pink cloud explodes in Izuku’s face before he can dodge it. It obstructs his vision of the villain and has him coughing slightly as he inhales a little bit of it.
“Fuck,” He wheezes out before hitting his coms, “Kacchan, I lost sight of the villain,”
“No fucking shit, Deku … I’m on his ass now,”
The roar of explosions sounds to Izuku’s left and he rushes back into the fight. Charging in he meets up with Katsuki, easily lifts him out of the way of an attack, and then steps to the side as Katsuki sets off another explosion. They work in sync, smooth and quick, with no need for verbal communication and soon enough Izuku has the unconscious and slightly smoking villain locked up in blackwhip.
Katsuki calls in the capture as their side kicks flock towards the villain to properly restrain him. Finally able to release blackwhip Izuku takes a heavy breath and does a mental once over. He’s a little sore – as to be expected from his training yesterday, he doesn’t feel or see any visible wounds, his hands are a little sweaty, his body feels warm, and he’s breathing a little heavy. Izuku blinks his eyes rapidly trying to tell if the cloud from the villain’s quirk had affected his eye sight.
He puts his hands out in front of him, holds up two fingers, waves them around a bit, yeah his vision was normal. However, his hands were trembling lightly, kinda weird. He was still breathing hard … Izuku frowns, he really hadn’t done a whole lot to be breathing this hard. The warmth in his body seems to grow hotter as his cheeks flushed red – that can’t be good. And his throat felt a bit dry too. He could really use some water, maybe it would help with the building heat inside of him.
“… ku,”
Izuku thinks back to the fight. The villain hadn’t used their quirk much. It was mostly a fist fight. He had been very nimble, quick to doge and run circles around them to try and corner them. Unfortunately for him, that was a strategy that worked better in one-on-one battles and not team ups – something that Izuku guessed the villain tried to avoid. The pink haired man had only panicked when Katsuki showed up on the scene.
“…Deku,”
Then there was his quirk. Using the flora that grew along his neck, arms, and legs the man could produce a cloud of fog? Gas? Pollen maybe considering it came from flowers. Izuku wasn’t sure what said cloud did, but both Katsuki and himself had tried to avoid it. A plan that Izuku failed, but at the very least it didn’t immediately harm him.
“Oi, Izuku!” Katsuki’s voice ripped through his thoughts.
Izuku blinks. Katsuki was gripping him by the shoulders like he was trying to shaking him out of his thoughts and Izuku realizes two things very quickly. The first is that Katsuki’s hands were warm – warmer than normal – and sent pulsing tingles through out Izuku’s whole body making him gasp sightly, legs wobbling. The second is that he’s fucking wet. Dripping actually. There was a hot mess between his thighs and Katsuki touching him was making it worse.
“I–” he can barely force himself to speak. There were other words forming on the tip of his tongue. Words that weren’t very appropriate at the moment.
Katsuki gives Izuku a once over, concern etching into his face. “Hey, Izuku look at me,” Not able to fully lift his head up, Izuku looked up at Katsuki through his lashes. “Shit … your eyes are pink and dilated as fuck,”
“Feel … warm …” Izuku forces out.
He's barely able to pay attention to what Katsuki was saying. Izuku’s mind was focusing on how nice Katsuki’s hands felt on him, and how handsome Katsuki looked at the moment, he really wanted to kiss him. Wanted to feel Katsuki’s hands all over his heated skin, gripping and pulling, sinking his teeth in too. Wanted to feel Katsuki’s lips hot and slick against his. Wanted to wrap his legs around Katsuki and–
“Fuck,” Yeah, that. “Of course this guy has some sort of sex pollen quirk,”
“Kacchan,” Izuku whines. Katsuki’s eyes darken at the slutty sound of his name falling from Izuku’s lips and tries to prevent the green haired man from sinking to his knees right this second.
“Yeah, yeah, I know. We need to get you out of here,”
And get out of there they do. Katsuki scoops up Izuku and blasts them back towards the agency. He’s only mildly distracted by Izuku burying his face in the man’s neck and trailing kisses up and down it, tongue flicking out to lick at his skin and sink his teeth down into it. They make it to the agency in record speed and Izuku vaguely recognizes their surroundings before he’s deposited on the bathroom sink counter.
Izuku immediately wraps his arms back around Katsuki's neck and pulls him into a kiss. A moan comes out of Izuku’s mouth as the heat that had been building up inside him shot up to full force. His whole body felt hot and shaky – he needed to be out of his clothes immediately. But he couldn’t stop kissing Katsuki. His lips felt too good, all wet and warm and their tongues glided against each other just right. Izuku was getting lightheaded already.
Katsuki growled into the kiss, hand gripping Izuku’s waist as he pushed forwards, deepening their kiss and forcing Izuku to rest his head and shoulders against the mirror. One of Katsuki’s gloved hands moved in between Izuku’s thighs and the man moaned loudly, hips squirming as his legs were spread open. Katsuki’s fingers press up against Izuku’s cunt and finds the material of his suit to be soaked.
“Goddamn,” Katsuki groans.
Just rubbing his fingers lightly up and down the area has Izuku screaming out. It feels too fucking good, has his eyes rolling back into his skull as he cums.
“K-Kaa– ah! Nnngh … c-clo…thessss,” Izuku slurs out through his orgasm.
“Fucking hell you came just from that? Shit … okay, let’s get this stupid suit off you,”
Izuku moans the whole time that Katsuki makes quick work of taking off his hero suit. Every touch since his orgasm just seemed to burn even more. His head was so cloudy with need and desperation when he’s finally naked even the cool sink counter doesn't do anything to help relieve him. The only thing he can feel is his cunt dripping, pouring out slick onto the counter like a faucet, and his heavy breathing. There was a heat deep inside of him that needed to be scratched.
So he sinks his fingers into his cunt. Practically wails at the feeling and starts to fuck himself hard. His cunt makes the wettest, slickest sounds he’s ever heard and it should be embarrassing but Izuku couldn’t care.
“P-Please! pleasepleaseplease fuuuck,” he sobs out deliriously.
His fingers are ripped out of his pussy and Izuku sobs, tears spilling down his cheeks at the lost. Big green eyes blink rapidly trying to make sense of why he had been stopped. But it doesn’t matter much when Katsuki’s hands are tugging at his legs, bringing them and his ass just over the ledge of the counter and spreading them wide. It forces Izuku to rest his weight onto his arms and upper back while he looks down with a shaking gasp as Katsuki buries his face in Izuku’s cunt.
The first swipe of tongue over his chubby clit as Izuku screaming. His head gets thrown back as drool slides out of his mouth and his hand grips Katsuki’s blond strands to push him in deeper. His hips roll up slightly to meet Katsuki’s tongue that runs through his sticky folds. Katsuki’s mouth was burning hot and eating him out messy. Izuku could feel the harsh breaths that Katsuki was taking through his nose against his bush.
Swiping up the slick leaking out of his hole, Katsuki pushes is tongue inside that pussy and they both moan in unison. Izuku feels his walls squeeze down on Katsuki’s tongue and sobs at the feeling of something finally being in his hole again. He practically forces Katsuki to fuck his cunt with his tongue by grabbing his head with both hands. Izuku pushes the blonds head back and forth into his cunt to stimulate his insides.
Red eyes look up at him and cause shivers to wrack down his body. Izuku finds himself cumming yet again, but his hips and hands don’t stop trying to fuck himself. Katsuki grabs his wrists and pins them down on the counter, makes a high pitched whine come out of Izuku’s mouth in response. But then Katsuki’s lips are wrapping around Izuku’s clit and sucking and Izuku fucking squirts. The guttural noise he lets out bounces off the bathroom walls and echoes.
Katsuki’s face is drenched in Izuku’s juices but he doesn’t care, just drinks down that slick and licks up more of it.
“So fuckin sensitive,” Katsuki smirks between Izuku’s thighs. Izuku locks his legs around Katsuki’s head to get him to continue eating him out.
The blond doesn’t waste any time getting back to it. Practically glues his lips and tongue to Izuku’s pussy and flexes his jaw to get nice and deep inside those pretty pink folds before sliding his tongue back inside that slutty hole.
“Yesss, fuck … m-more,” Izuku moans.
Izuku thinks he might have cum at least three more times before Katsuki pulls his mouth away and he still whimpers and sobs for Katsuki to come back. He was so overwhelmed and sensitive but it still wasn’t enough. No, every orgasm just made the insatiable heat in him grow worse.
His hands go back down to rub at his clit and fuck his cunt. God he couldn’t even attempt to think about anything at all. It was just a constant stream of ‘cumcumcum’ over and over.
“He really fucked you up … shit, Izuku you sound like a fucking whore,” Katsuki says breathlessly as he undoes his pants.
Whatever noises Izuku was making, he hadn’t even realized them. The only word he heard was ‘fuck’. Izuku opens his eyes – not even sure when he closed them – and his eyes lock immediately onto Katsuki’s cock. His mouth waters and his pussy drools even more making a puddle underneath him. He needed that cock – he needed it so bad.
“Kacchan! K-Kacchan!”
Katsuki positions himself between Izuku’s legs, cock sliding against those scarred hands working Izuku’s cunt. Immediately Izuku is grabbing at Katsuki’s cock with his soiled hands and pulling it closer to his pussy to rut up against it. Timing his thrusts with Izuku’s Katsuki grinds with him, getting is cock lubed up with Izuku’s slick.
“Yeah? You want my cock baby?” Katsuki breaths against Izuku’s lips, their foreheads pressing together.
“Gimme,” Izuku says as he nods his head.
Katsuki laughs but helps Izuku guide his cock into that sloppy hole. Izuku’s eyes roll back and his mouth drops open in a scream as he’s finally, finally filled up the way he desperately needed. Arms wrap around Izuku’s thick freckled thighs and slam the man fully down on Katsuki’s dick.
“Fuck, you’re a fuckin mess. Gonna cum again? Gonna cum just from me filling up this slutty cunt? Huh baby?” Katsuki teases.
Izuku though just digs his nails into Katsuki’s hips and does just that. He trembles through an orgasm while Katsuki pulls his hips back just to slam right in to the hilt, knocking against Izuku’s cervix. Katsuki sets a brutal pace of fucking, hips pumping sharp and fast and deep. Izuku needed him in his fucking guts so this was perfect. Every thrust is accompanied by the loud smacking of their skin meeting and Izuku’s pussy getting stirred up.
It felt like every inch of him was getting pounded. The sensation was sending tingles throughout his whole body and Izuku couldn’t stop shaking and clenching and cumming. He can’t remember ever cumming this much, but this quirk had his body on a nonstop high. It should have been painful by now but it wasn’t. Wave after wave of pleasure kept hitting him until his brain had fully turned into mush.
All he could do was take what Katsuki was giving to him.
Katsuki presses kisses into Izuku’s jaw and trail down to his neck, sinks his teeth in to make Izuku scream and tighten up on him even more. He leaves several deep hickeys up and down Izuku’s skin, imprints of teeth too, and then runs his tongue over the area to sooth it. Izuku moans and searches for Katsuki’s mouth so they could kiss. Their lips meet and muffle some of the noise that Izuku was making. Too bad it only highlighted the sound of his pussy in both of their ears and caused them to fuck harder.
“Sloppy little cunt just sucking me in, dripping all over the damn counter, screaming like a whore, fuck Izuku,” Katsuki growls out. “Maybe filling you up with my cum will get you to calm down,”
Izuku gasps out a moan, pussy clenching harshly at the thought of being filled with cum, “P-Please,”
Their lips meet in a kiss once again and Izuku’s nails make long scratches down and across Katsuki’s back. Tongues gliding together, teeth biting and tugging at lips, and then Katsuki unwraps one of his hands from Izuku’s thighs. It shifts the angle a bit and makes Katsuki sink in even deeper. They both groan at the change and Izuku feels fingers start to rub at his clit.
He chokes on a moan and fresh tears spill down his cheeks, mixing in with their kisses. Izuku’s mind was floating somewhere, he couldn’t stop his legs from violently convulsing as Katsuki forces him into another orgasm. His poor abused hole and clit keep getting worked over as Katsuki’s thrusts get quicker and his fingers stop rubbing to instead land light spanks down on Izuku’s cunt.
Right as Katsuki pushes all the way in and unloads his cum, Izuku squirts. It takes a moment for Izuku to realize he wasn’t breathing so he gulps in lung-fulls of air when he does. He was dizzy and his body was throbbing but the all consuming heat that had covered his brain lessened. Izuku slowly regained control of his breathing and his limbs and looked down between his legs to find his cunt over flowing with Katsuki’s thick white cum. It makes his pussy flutter just looking at it and Katsuki groans.
A gentle rock of Katsuki’s hips has Izuku sobbing. Oh god, he was sensitive.
But Katsuki keeps going. Gives small thrust of his still hard cock through Izuku’s sloppy cunt.
“Fuck that feels good,” Katsuki mutters. He leans up a little straighter and turns Izuku around so his chest was pressed against the counter instead. Izuku could see himself in the reflection of the mirror and quickly averted his eyes. His face was terribly flushed and that pink in his eyes that Katsuki had mentioned earlier was still lingering.
“K-Kacchan, wait I’m still … ah, shit–” Izuku’s words get stuck in his throat as Katsuki’s hands wrap around his waist and the tips of his toes reach the ground.
The first real thrust Katsuki makes has Izuku squeaking. It’s so loud and wet that Izuku can feel it. He feels Katsuki’s cum sliding out of him and splattering onto the floor. Katsuki holds Izuku’s pussy lips open and watches as his cock pushes his cum in deeper and that swollen red hole grips onto him.
“Mmh, one more load should fix you. Your cunt is so fuckin hungry for it,”
Izuku feels his cheeks flush even further in embarrassment but he can’t really protest when Katsuki was fucking him so good. So he just takes it, legs trembling and slutty moans leaking out as he felt every inch of Katsuki’s cock spreading his raw insides open. Every time Katsuki’s cock head hit his cervix he let out a little wail at the pressure. Pain and pleasure had mixed and his mind was quickly getting scrambled again from the brutal thrusts.
Then a hand is yanking at Izuku’s hair, forcing him to look into the mirror.
His eyes focus on Katsuki first. Just seeing the man with his pants shoved down and tank top riding up on his skin to slightly show his abs as his hand gripped Izuku’s waist and bounced his fat ass back onto his cock was like a dream. Katsuki’s own cheeks were flushed slightly and his red eyes looked dangerous and possessive. But Katsuki didn’t want Izuku’s focus on him, no he wanted Izuku to look at himself.
“Look in the mirror baby. See how fucking gorgeous you look?” Katsuki says lovingly but with a growling tone.
Izuku looks at himself and grows shy. He did look pretty like this – eyes blown wide, cheeks a permanent red making his freckles stand out, pink lips swollen and parted open, and his hair was sticking to his temples as well. “Yes,” he gasps out.
“Give yourself a little kiss, Izu,”
With a small whimper Izuku presses his lips to the mirror and kisses himself. Just as he does Katsuki’s fingers find his clit again. A sobbing moan comes out of Izuku as he squirts all over Katsuki’s cock while kissing the mirror. Katsuki presses in deep and with a groan dumps his second load into Izuku’s pussy.
Katsuki softly works Izuku through his orgasm, milking his own cock in the process and finally they slump against the sink counter top in exhaustion. Their harsh pants filling the air.
“Fuck, that was crazy … look at me,” Izuku does his best to look back at Katsuki. “No more pink … you’re all clear,”
“T-Thanks Kacchan,” Izuku sighs out relieved.
They take a while to cool down and then wash themselves off a bit in the sink. Katsuki even cleans up the counter top and floor while Izuku redresses himself. Izuku’s hair was still a little fucked up, the fresh hickeys on his neck weren’t able to be hidden, his cheeks were still a little red, and his lips were swollen, but other than that he looked … decent.
Where Izuku sheepishly shuffles out of the bathroom, Katsuki was glowing. Their sidekicks are all slightly horrified and flustered having just listened to Pro Hero Deku get railed within an inch of his life by Pro Hero Great Explosion Murder God Dynamite. Katsuki glares at them and they all quickly turn away and go back to their work.
