For once seeing a villain carted away filled Izuku with a special kind of dread.
Kacchan had done it.
He had made him horny for winning.
Izuku quickly covered himself, blending the motion into a professional stance as the police approached him to discuss the capture. Weeks of patrol with Pro Hero Dynamight, always ending with those fiery red eyes dragging him into an alley or behind a debris pile. Too much pent up adrenaline sometimes. Just grateful to be alive on other occasions. Always as exciting as the capture itself when those lips captured his...
And now here he was, knowing the media wasn't far behind and praying the built-in cup of his suit would disguise the raging hard on he had since the click of the cops quirk canceling cuffs. The dust had cleared, he had seen the villain was defeated and suddenly things were… less than hero-appropriate.
Explaining the villains quirk quickly – a bank heist gone wrong resulting in several hostages getting stuck in the walls (Togata was already on it) – Izuku couldn’t help but glance at a nearby clock. It was only 3:30pm. Where would he be at this hour? It was his day off – now that they were actually required to take days off from hero work. A new requirement put in place by the rebuilt hero commission and strictly enforced by Hawks at the helm. If Izuku dodged the reporters calling his name from the police barrier and using gear shift maybe –
“Hero Deku.” Izuku's attention snapped back to the present. A medic, by her uniform, was standing where the officer he had been interviewing once stood. When had he left? How long had Izuku been standing there with his stupid hands folded in front of himself like a soldier trying not to pee.
“Hero Deku, do you require medical assistance? Your cheeks are flushed but you seem… pale. Are you hurt?”
“No! No, no, no, I am fine. Thank YOU!” Izuku squeaked a little too loudly in that last part when she reached out a hand to feel his face. His cheeks were definitely burning now. Oh my god, he could see the headline now.

Hero Deku–
“Deku!” Uraraka, shouted from the skies above somewhere. Thank goodness.
“I’m sorry,” Izuku says, waving off the medics' worried expression. “I’m fine but thank you for your concern. I’m sure there’s someone around here who could use your hands – I mean, help! Use some help! Uh– Bye!” Before launching himself into the sky to meet Uraraka.
A quick debrief in the air had him firing off in another direction to handle another emergency downtown with Uraraka riding along to help with a collapsed building. Then back to midtown for a runaway car possessed by a spirit-based quirk. Then an entire smuggling ring.
It’s fair to say by the evening, Deku had saved many lives and consequently defeated more than his share of villains. Locking them all away with a hard click of quirk suppression cuffs while he tried harder and harder not to twitch under the strain. When he got back to the apartment, he was panting.
“Welcome home.” A voice greeted him from the direction of the kitchen. Izuku, barely remembering to stomp out of his reinforced hightops in the entry, stomped after it.
“You.” He said accusatorily with a jabbing finger. Katsuki, oblivious at the stove with his back apron on that said “DIE” in a fiery exploding script, hummed in response. A glance at the mirrored reflection of Deku off the stove backing, Katsuki paused in his stirring to tap the hearing aid dangling from his ear.
“Did you say something? And why are you–” His glance over his shoulder turned into a familiar turned to glower as Izuku furiously strode across the distance between them. “Are you still in your costume? Nerd, you’re filthy. Get out of my fucking kitchen, you walking dirtbag –” Whatever he was going to say next was quickly cut off as Izuku fired up OFA just enough to snatch Katsuki up by his trim waist, turning off the stove with black whip and zip back to the counter to slam Katsuki on it.
“What the fuck.” Katsuki crackled, small pops in the air around him in reaction to the sudden moves. Izuku, meanwhile, was between his knees and gripping Katsuki’s hips hard enough to bruise through the well worn sweatpants. It was a physical effort to not snap his teeth in the blonde’s scowling face and instead use his words.
“This is my problem, Kacchan.” Izuku hissed. Yanking Katsuki with emphasis to drag their groins together. Even through the apron and hero suit, Izuku’s raging state was obvious.
Katsuki’s expression went through a quick transition from anger to surprise to a self-sastified sneer.
“Wow, shitty Deku. Get lucky on patrol?” He drawls.
“No, Kacchan, I most certainly did not.”
“Really?” Katsuki’s sneer became even more saccharine as he rolled his hips as much as Izuku’s tight grip allowed, eliciting a groan from the other hero. “sure feels like it to–” Izuku, in retaliation, gripped those hips even tighter. Leaning up to touch their foreheads together, he grit between tight teeth,
“Save to win.” Katsuki paused. His salacious grin dropping for just a moment.
“Oh,” The sexual tension held its breath for a moment. Izuku clearly strung tight enough to snap as he pressed their foreheads together tighter. Red meeting green. Katsuki, in response, wiped off a sweaty palm on his apron (they would have to wash out the nitroglycerin later) to cup his partner's face. Thumb brushing over the flutter muscles of his jaw.
“Win to save.” A call and response, repeated across the years since AFO.
Deku smashed their lips together and groaned at the first taste. Katsuki battling back with equal fervor. It was like licking a battery, sharp and electric on his tongue. But it was Deku. And they always fought whether they were sparring or fucking. When Izuku broke the kiss to start peeling down the collar of his worn tshirt, leaving wet marks in his wake.
“Holy shit, Deku. What is up with you today?”
“N’thing.” Izuku’s words are smeared and muffled against Katsuki’s collarbone, the limit of his reach with his shirt still on. Unacceptable. He quickly divests of the material, ripping it off above his head. “Villain. Big villain capture. Not there. Had to get home.” He punctates the last statement with shoving his hands beneath sweatpants and boxers to feel as much skin as possible.
“Villain? What… wait.” Katsuki sounds dazed –possibly from having his shirt and apron unceremoniously whipped over his head and leaving his explosive spikes more like dandelion fluff. Or it could be the attention stupid fucking Deku is not lavishing on his sensitive chest. Not that the great Lord Murder could be distracted by such menial things. Izuku, having finally found his way to a darkening nipple, bites down before pulling one hand away to get at his own belt. The utility belt collapsing to the kitchen floor with a bang seemed to shake Katsuki back to the conversation.
“Wait!” Grabbing freckled cheeks, he drags Izuku’s face off him to meet his red gaze. Pupils blow wide in forest green irises meet his looking glazed. Cheeks flushed and lips red from kissing. It doesn’t take long before it clicks.
“Izukuuu,” Katsuki drags out the vowels slowly. Grinning wide lips. Izuku licks his in response, pressing into a kiss that Katsuki keeps quick. Guiding him into his neck where Izuku happily starts kissing again as Katsuki whispers in his ear. “Win to save.”
Izuku whines and ruts against him in response. Katsuki laughs.
“Kaaacchaaan.” The blonde still laughs but locks his ankles around stocky thighs drawing them tight together.
“What, nerd? Embarrassed I’ve Pavlov'd you into sex after every victory?”
“Kacchan!”
“Relax, nerd. I like it.”
And that was that.
