Work Text:
Katsuki was going to explode. What in the ever loving fuck was this? He pointedly ignored Deku’s panicked spluttering, dropping his bag on the floor and stalking over to the bed.
Singular bed.
Just the fucking one.
For the both of them.
It wasn’t even a fucking big bed. They couldn’t just curl up on opposite sides, build a wall of pillows in the middle,and call it good enough.
There was no way the two of them–big-ass grown men, heroes built like a fucking brick wall–could lay on this tiny ass motel bed without their limbs overlapping without incident. Katsuki would end up either exploding Deku or himself before the night was over. And not just because Deku was a heat seeking missile of a cuddler or that Katsuki was bound to wake up with sticky briefs just from the sheer proximity of the nerd.
The last time they’d shared a bed had been in the darkest nights after the war, when they were still recovering and needed to know the other was alive.
And since then? They’d struggled in this fucking limbo of You’re My Closest Person but also We’re Not Together and it was going to be the goddamn death of him. Again.
“I’m going to kill that Icyhot bastard,” Katsuki growled, kicking the bed. It wobbled and creaked precariously, knocking into the pockmarked wall.
“Kacchan, it’s not Shouto’s fault that the motel ran out of rooms,” Deku tried to placate, plopping his overnight back onto the rickety desk.
“It’s his fucking fault we’re out on this stupid mission,” Katsuki crossed his arms. “And he couldn’t flash his fucking black card to at least get us two fucking beds? Our fucking dorm rooms had bigger beds than this piece of shit!”
Deku sighed and chewed on his bottom lip. “I can sleep on the floor, it’s not a probl–”
“And then I have to deal with your fucked up back in the morning? You gonna catch that fucker without your full range of motion?”
“Then the tub! I’ll sleep in the tub!” Deku threw his hands, face pink with exasperation. He stomped over to the bathroom, threw open the door, shrieked, and came running back out with wide eyes. “I’m not stepping foot in the tub.”
Katsuki raised an eyebrow. When Deku didn’t offer any further explanation, Katsuki groaned and went to see what made the nerd look so freaked. He took one glance at the many legged monstrosity crawling up the side of the porcelain and slammed the bathroom door shut.
“I’m going to blow this whole fucking place up,” Katsuki snarled, hoping the waver in his voice could be misconstrued as anger and not fear, “What are they gonna do? Tell me no? I’m a fucking hero!”
“Kacchan, no! ” Izuku said. “We can’t afford another destruction of property claim, our insurance won’t cover it anymore.”
“Fucking fine ,” Katsuki stomped toward the bed. “Let’s just get some fucking sleep. I’m exhausted.”
“Um,” Izuku chewed on his fingernail this time. “Are you going to be okay? Y’know… sharing a bed? It’s been a while…”
“Hah?! You trying to say something, shitnerd? Think I can’t handle a little fucking… sleeping together? Fuck you!” Katsuki had to turn away from him; he couldn’t let Deku see just how flustered the thought made him. He could feel the heat pooling in his cheeks. Christ. What was he, a fucking teenager dealing with some fresh new crush?
It was just one fucking night sleeping next to the stupid love of his life. He could make it through the night without ruining everything. He was fucking Great Explosion Murder God Dynamight, he could do anything he put his mind to.
(Except confess.)
“Okay, Kacchan,” Deku came up to his side, already wearing his stupid little hero pajamas. “It’ll be like old times!”
Katsuki wanted to retort, say something snarky, but his brain short circuited; Deku was wearing Dynamight branded pajamas . What the fuck. Why did the nerd look so good in his colors? Like he fucking belonged to him–
Izuku must have caught him staring, since he flushed a pretty pink and started to stammer. “Oh, uh, well… these were… um, they’re really comfy? And I didn’t know we’d be… um, and they were my cleanest pair–”
“Shut the fuck up,” Katsuki pushed Izuku face first into the bed. Mistake. That was a mistake. Now he got an eye full of his orange X branded around Deku’s thick thighs. Oh fuck, Katsuki was going to bust a nut in his goddamn pants just from the sight alone. He tore off his shirt just to break line of sight.
Even muffled through his shirt, he could hear Izuku’s melodious little giggle that cut off with a sharp gasp. Katsuki could feel emerald eyes burning holes into his chest. So of course he flexed (just a little) as he tossed his shirt towards the desk.
Deku wasn’t even aware that Katsuki was watching him right back now, even as he peeled his pants off. He wondered how long he could stand there, at the edge of the bed in his briefs, flexing random muscles until Deku caught on.
At least five minutes. Five minutes of Deku’s hungry gaze flicking from muscle to muscle, mouth slowly dropping open. At one point, Katsuki swore he even saw drool pooling at his lip. The attention made Katsuki both preen and overheat–why the fuck did he never notice Deku looking at him like that?
Well, he had noticed, but he never really put much thought to it outside of categorizing it as just another bit of hero worship.
But this? This felt different. This was almost… primal.
“Oi,” Katsuki growled, his voice low and scratchy. He’d barely been able to breathe under Izuku’s intense watch.
Deku, the dork, scrambled back, red in the face. He hid behind one hand and the other flew down; was he adjusting himself?
No, that couldn’t be right.
“Move over, shithead.” Katsuki said, shoving Deku over across the bed.
“Waaahcchan!” Deku wailed, the absolute dork. He rolled over so he was pressed against the wall and pouted up at him. “So mean!”
“You’re only just figuring that out?” Katsuki smirked, ripping the sheets up and throwing himself onto the bed. “You’re about twenty five years too late to that realization, nerd.”
“Meanie,” Deku huffed and he wriggled under the covers in his goddamn Dynamight PJs. “You’re… uh… not going to put on any jammies?”
Jammies.
“No, Deku, I don’t wear jammies to bed,” Katsuki forced himself not to roll his eyes, despite the overwhelming urge to do so. Instead he turned to face Deku straight on and smirked. “I usually don’t wear anything. Would you prefer that?”
He could practically see the steam coming out of Deku’s ears, his face flushed such a beautiful red that it nearly became Katsuki’s new favorite color. Green eyes blinked rapidly, Deku’s mouth opened and closed and opened again. For once, the nerd was rendered speechless.
Katsuki’s body moved before he could tell it to; he gently closed Deku’s mouth, fingers caressing his jaw. He whispered, “Night, nerd.” and turned back around and pretended to sleep.
He wasn’t going to get a single second of rest tonight. Not with how close Deku’s body was, how his heat radiated off him in waves, how the smell of him filled Katsuki to bursting. He could feel Deku trembling behind him, unsure of what to do or how to react; Katsuki felt the same, but he at least schooled his body into motionlessness.
“Kacchan…” Deku whispered. The bed creaked as he shifted.
Katsuki stayed silent, staring at the far wall through the darkness. He only let himself breathe slow and deep. He felt a palm rest between his shoulder blades, the touch electrifying. Katsuki just barely suppressed a shiver.
“I know you’re not asleep,” Deku’s warm breath cascaded over Katsuki’s skin. “You snore.”
Katsuki twisted around to glare Deku down, face pinched in a snarl, “I do not!”
Mistake. Mistake mistake mistake.
Deku was close. So goddamn close, their noses nearly touched. Katsuki’s every breath was one taken from Deku. Izuku’s emerald eyes twinkled with mischief. Little fucker.
Though now that he was facing Deku, the hand that had been pressed do his back was splayed between his pecs. Flexing one and then the other, he watched with sadistic glee as the mischief turned to panic before it quickly turned to a dark want that bordered on desperation. His freckles were damn near buried under the wave of red that burned across his cheeks. He looked delectable.
Two could play at this game.
And Katsuki would win.
“ Izuku, ” Katsuki growled, letting his voice rumble low and deep. He reveled in the sharp intake of breathe from the nerd.
Deku’s eyes roved from where his fingers were still splayed between Katsuki’s pecs, up his muscled shoulders and to his face. Katsuki brought his face just that much closer; their noses touched and when he spoke, their lips brushed in a weak imitation of a kiss. In a moment of brief nerd-induced insanity, Katsuki threw his arm around Deku’s waist, pressing his palm against his lower back and pulling him close.
“What are you going to do, De-ku ?”
His eyes blew wide. “K-Kacchan?”
“You couldn’t leave well enough alone, could you?” Katsuki hissed through his teeth. He wished Deku wasn’t wearing those stupid pajamas, so he could touch his bare skin. He brushed his pinkie against the edge of the shirt, fiddling with it, tempting himself. “You just had to poke the bear, hah? You knew what you were doing with this shit, didn’t you?”
Katsuki snapped the waistband of Deku’s pajama pants. Izuku wriggled, hips bucking closer to him. If Katsuki just shifted his thigh, it’d be like Deku was humping his leg. Fuck .
“You know just how much I love seeing you in my colors,” Katsuki said into Deku’s ear. He let his teeth drag along his jawline, nosing into the pulse point just under his ear. “You like how it makes it look like you belong to me, don’t you?”
Izuku shivered and turned his head to bare his neck to Katsuki.
“Yes, Kacchan.”
The whisper was like a punch to the gut. His hand curled into a claiming clutch at Deku’s back, fingers bruising freckled skin. Katsuki jerked them close together, their clothed erections rubbing against each other. Izuku moaned right in his ear and it took every ounce of self control for Katsuki to keep from jizzing in his pants. Again.
The fuck did Deku turn him into?
Deku’s crooked fingers scrabbled for purchase around Katsuki’s shoulder. One hand squeezed his muscles, groping along his shoulder and chest, and the other buried in his hair and tugged. Katsuki hissed, the prickling pain-pleasure of it zinging down his spine.
“Kacchan, Kacchan please, I…” Deku gasped for air when Katsuki’s hand slipped under his shirt so he could dig his nails into his skin. He was like a drowning man reaching for salvation, and Katsuki was his air.
Katsuki ground their hips together.
“You’re mine, ‘Zuku,” Katsuki said. Though he meant it like a statement, it cracked into a question.
“Yes, yes, all yours Kacchan, just yours, please ,” Izuku whined, pulling Katsuki closer to him and mouthing at his neck and jaw. “Please, please, Kacchan, I need you–”
“I’ve got you, angel,” Katsuki purred, nuzzling into the junction between his neck and shoulder.
“Kacchan!” Deku wailed, “Kiss me, kiss me, please, please, kiss me!”
“Needy,” Katsuki growled before sealing their lips together.
Katsuki’s ears rang like he’d just set up a thousand explosions, his skin tingled like he stood just a little too close to Deku when he activated his quirks, and he sent an apology to Edgeshot for the way his heart was hammering against his ribs like a wild animal desperate to escape. It was all so much, too much, but fuck if it didn’t feel like everything was finally right in the world.
Why hadn’t he done this sooner, why hadn’t he just crowded up on the nerd and just let it happen? What had he been so afraid of?
Katsuki pulled back to breathe and opened his eyes (when had he closed them?) and realized exactly why.
The way Deku looked up at him, through watery lashes and with glassy eyes, cheeks flushed so bright and lips kissed raw, Katsuki realized he would break the world for this man. Never mind that Deku was very much able to take down the world on his own; he wasn’t the most powerful hero for nothing.
But the way he looked in his arms? Staring at Katsuki with unfiltered admiration and devotion? Katsuki would do anything and everything to protect that, to keep those eyes on him. He’d eschew all of society if it meant he could keep Deku at his side. He felt a little insane at the thought, at the burning feeling surging through him like a tidal wave. He actually felt like he understood where that Toga bitch was coming from.
He wanted to break open his chest and gather Izuku inside it, keep him safe between his ribs and close to his still beating heart. He wanted to never let him go. He could finally understand why everything about Izuku made him so irrationally angry–it wasn’t even anger, it was just pure, unadulterated love , in the most clinically insane way he’d ever come to know it.
Izuku cradled Katsuki’s face in his palm and he nuzzled into it like some cat seeking warmth. Katsuki didn’t blink; he kept his eyes laser focused on Deku’s. Izuku’s eyes softened.
“I want it all too, Kacchan,” Izuku whispered. Another gut punch. Had he said it all out loud? Was he that easy to read? His walls had crumbled from the first touch and Izuku could peer into his soul without obstruction. There was nowhere left to run, nowhere left to hide, not here on this tiny ass motel bed, pressed to each other like they were, sharing space and air and heat. “I feel it all too.”
“Fuck,” Katsuki so eloquently said.
“Yeah,” Izuku hummed, like he knew exactly what he meant.
“I’m not letting you go ever again, nerd,” Katsuki said, tightening his grip around Izuku’s waist.
Izuku threaded his arms behind Katsuki’s neck, “I’m not going to either, Kacchan.”
They didn’t sleep much that night, trying to figure out the most comfortable way to press against each other, to fit their limbs like puzzle pieces, and still be able to make out and rut against the other. The only reason they didn’t go further (besides the lack of lube and not wanting to send Deku out onto the field with a sore ass) was because Katsuki insisted on wining and dining the nerd first, properly , before taking him up to his own goddamn apartment with his big hero-sized bed.
Like fuck was Katsuki going to let their first time together be in the middle of some bum-fuck nowhere crappy ass motel. He was going to do this right, treat Izuku right, and let it set the highest of bars for the rest of their future. Plus fucking Ultra, and all that shit.
