Deku's Extraordinary Playlist - Chapter 6 [NSFW] [FINAL]

Izuku tensed up before he’d even fully processed the reason for it, jaw clenching when he spotted the familiar faces lingering in a hospital hallway. Right from the beginning he’d been against the decision, had argued with anyone who would listen, but in the end, a handful of U.A. students hadn’t been enough to make an impact. The Hero Public Safety Commission, despite every fibre of Izuku’s being screaming against it, had pardoned the former villains – though he used the word former very loosely, he still wasn’t convinced.

He squared his shoulders like it was second nature, preparing himself for a fight, but before he could even take a step closer, Hawks was blocking his path. He stood between Izuku and the “former” villain, eyes narrowed, and Izuku’s quirk buzzed beneath his skin in response – if looks could kill, Hawks would have had Izuku at death’s door.

“Deku,” he said quietly, his forced politeness not enough to mask his wariness.

“Hawks.”

“Good to see you up and about again.”

“Yeah. Here for a check up,” Izuku nodded, eyes drifting to the pierced, scarred face beyond Hawks’s back. “And yourself?”

“Escort.”

“Fun job, I’m sure.”

Izuku knew Hawks had been one of the biggest proponents for the pardon, had even been the one to propose assigning willing heroes to supervise various villains who qualified. He also knew that the only reason Dabi was standing there was because of Endeavor. The man himself had conveniently retired in time to not supervise any of the “reformed” villains, but had pushed for forgiveness for his son, for the man who killed hundreds, maybe thousands of innocent people just because of his Daddy Issues. Hell, Izuku had plenty of those himself, and he had never turned to murder.

“It has its moments,” Hawks agreed, raising an eyebrow. “Like keeping away any self-professed do-gooders who think they know better than the Commission does.”

“Don’t we all know better than the Commission does?” Izuku snorted, folding his arms. “You know that as well as I do.”

“If you think I’m letting you start anything, you’re sorely mistaken, Twelve.”

Izuku scoffed, but didn’t dignify it with an answer, only shooting another glance over Hawks’s shoulder to look for flames. Hawks apparently took that as a threat, from the way he took another step forward, rolling his shoulders back and standing a little taller.

“It’s fine,” Dabi said quietly. “You don’t need to fight all my battles, Hawks.”

Izuku wasn’t sure exactly what he’d expected to come out of Hawks’s mouth in response, but it certainly hadn’t been song. God damn it, this was not the time.

Then again, when was it ever?

The words were a little too on-the-nose for Izuku’s taste, even after every other piece of nonsense he’d put up with under the damn quirk effects. Burn Alive indeed – Hawks had come close once, after all. Of all people, surely Hawks should have been the one pushing to keep Dabi in jail. But here he was, willing to start a fight in the halls of a hospital with the number twelve hero – and okay, sure, Hawks was technically number one now, but Izuku maintained that it was not a fair contest that had kept him there. He was pretty and flirty, loved by all the women of the nation, not to mention he had some kind of pull with the Commission after all his undercover work. If it was a fair contest… Well, Izuku probably still wouldn’t be number one. Maybe Katsuki, with his insane number of villain captures. At any rate, they’d both have been closer at least.

But here was Hawks, the number one hero, standing between him and a potential threat, singing about how he would give his own life to protect the man who had killed so many others. It made no sense, even for a hero, and Izuku said that as someone who had many times come close to dying to save someone else. Those memories haunted him every day, made him tremble in the night as he woke from nightmares, and while he didn’t regret saving people – not even close – he still wished he didn’t have to remember what it was like to come so close to his own demise. Hawks had to remember that feeling too, had to remember whose hands he’d almost succumb to, whose flames he’d almost succumb to.

Unless…

Was there more going on?

The way Hawks looked at Dabi as he sang was… Different. It wasn’t the obligation of a hero assigned to supervise him, wasn’t even the look of someone doing it as a favour to the former number one, the man Hawks had looked up to as a child. For the first time, Izuku saw something emotional in Hawks’s face, something he couldn’t just carefully cover up, as he repeated those same words over and over. He would do anything for that man. Which meant…

Oh no.

When Dabi took Hawks’s outstretched hand, Izuku knew for sure.

And he really, really wished he didn’t.

He groaned when the nurses began twirling in from the examination rooms, forming a little congregation of back up dancers who circled around the group, penning them in. Izuku couldn’t have made a run for it even if he tried – and boy, was he tempted – instead doomed to his fate, watching Hawks and Dabi give each other sappy looks that he never thought either of them was capable of.

It wasn’t even a sappy song, for crying out loud. Why was this what was coming out of them?

He tried his best not to listen to the words, to just ignore it or tune it all out, but still a few managed to worm their way in, in the unusually rough tone of voice that came out of Hawks. And unfortunately… Well, some of it made sense.

Ugh. Damn his capacity for empathy. It should have been Katsuki who got to hear and see all the weird shit, he would have just laughed at them and walked away.

Hawks had lived a weird life, though, Izuku knew. Had spent his years conforming to what the Commission asked of him, what the public needed from him. He wouldn’t have just decided to date a villain on a whim, would never have just accepted it and decided to roll with it, it had to have taken… Years of inner turmoil, Izuku suspected. Maybe he hadn’t even admitted to it, in reality. Izuku only saw the deep, hidden thoughts, after all – maybe in reality, even Dabi didn’t know.

Hawks was terrified, that was for certain. Of exactly what, Izuku might never know.

For a moment Izuku thought it was over, and he opened his mouth to speak, only to find the pair still gazing into each other’s eyes like there was no one else in the world – not to mention the cluster of nurses and patients still gathered around them, assembled in a neat little row and tapping their feet in time. One of the older nurses even did some weird little jig with her arms, swinging her hips from side to side, and Izuku had to stifle his snort in his hand as he watched. They took turns piping up with a little yeah in time with the beat, not even moving around the circle like Izuku would have considered sensible, but from random people in every direction, constantly making him jump. It was like a game of verbal whack-a-mole, and Hawks just stared into Dabi’s eyes the entire time, like they could say everything they needed with a look alone.

Izuku hated that he understood that feeling.

Izuku imagined the hand on the small of Hawks’s back had to be uncomfortably warm, like Shouto’s left side when they sat next to each other in the heat of the summer. Hawks didn’t seem to mind at all, though, letting the touch pull him a little closer, their faces only inches apart.

When Hawks sang again, it was much softer, as if his words were intended for Dabi and Dabi alone, like the world around them had just ceased to exist. Izuku supposed it had in a sense – this was all Hawks’s internal monologue of sorts, so to him, all that existed was what was in his eyes.

“You’d do anything for him,” Izuku whispered. “Even if it meant burning alive under his quirk.”

For the first time in Izuku’s life, he saw Dabi smile faintly, giving Hawks a look that was almost as soft and sappy as the one he got from Hawks in return. Hawks’s fingers tangled in Dabi’s shirt, pulling him even closer, until the feel of his words had to be reaching Dabi’s lips, sharing the same breath. And this time, Dabi joined him, returning those same words, the same feelings. This wasn’t some unrequited thing Hawks had developed, this was… More. Much more.

Izuku breathed a sigh of relief when the nurses and patients all walked back to their rooms like nothing had ever happened, Hawks’s eyes hardening again as he stared Izuku down. Reluctantly, Izuku took a step back, holding his hands up in surrender. He knew how to pick his battles, and after just a day of Kacchan being his, he was well aware of how Hawks must have been feeling. Izuku would do anything for his Kacchan, and it seemed like maybe Hawks and Dabi felt the same, regardless of how inexplicable Izuku found that.

Hawks relaxed a little when Izuku stood down, just in time for another familiar face to join them, eyes widening when he spotted Izuku only metres away.

“Is your check-up today?” Shouto asked, glancing at his phone. “That came around quickly. Where’s Bakugou? Not with you?”

“He’s working,” Izuku smiled faintly. “He offered to take the day off but I made him go. I’m doing fine, so it’s not a big deal.”

“I’ll come, then. I just came to make sure Touya was okay, but he seems fine now.”

Touya.

“Right,” Izuku nodded, jaw clenched again. “I’m sure Touya appreciates it, you’re a good… brother.”

“It’s just nice to have him back,” Shouto smiled softly, patting his brother’s shoulder. “It took way too long.”

“Yeah, I’m sure it is.”

Dabi – Touya, he should probably try to get used to that for Shouto’s sake – ruffled Shouto’s hair lightly, and Izuku wasn’t sure he’d ever seen Shouto look happier than he did in that moment. As much as he hated the guy, it seemed like Shouto and Hawks were going to make sure he stayed there, and Izuku supposed he was going to have to get used to it.

“I should get to my appointment, they’ll be wondering where I am,” he mumbled. “You don’t need to come with me, hang out with your… brother.”

“I don’t mind.”

“No, really,” Izuku smiled awkwardly. “Have fun, I’m okay.”

“Alright, if you’re sure,” Shouto nodded. “Uh, I’m hanging out with Kirishima again tonight, by the way. He’s… Cool.”

“Baby brother finally found a boyfriend,” Dabi – Touya, damn it! - smirked. “It’s about time.”

“Izuku set us up,” Shouto shrugged. “You’ve got him to thank. And uh… I guess I should, too.”

“It’s my pleasure! Really! I’m glad it went well, I know you were just kind of humouring me at first.”

“Yeah, but I’m glad I did.”

“Good,” Izuku smiled, much more genuine this time. “Let me know how it goes?”

“And you, for your appointment.”

“I will! It was nice seeing you!” he paused, shooting Hawks a shaky smile. “And you, Hawks. I… Trust you, okay? Just… Keep it under control.”

“I don’t need to,” Hawks narrowed his eyes again. “But I would, if it came to it.”

“I’m glad to hear it.”

─────

“How come it was never me?”

Izuku froze in his tracks. He’d just been sharing the dumb story from the hospital, giggling over how weird it all was and hoping Katsuki might reassure him, he’d never expected that to come back at him.

“What was never you?” he asked, tilting his head slightly to examine Katsuki’s tense jaw and hunched shoulders. “I’m sorry Kacchan, I don’t know what you’re upset about.”

“You have all these weird-ass moments with people about… Their feelings and shit. How come I never had that moment?”

“Because you weren’t the one hit with the quirk? I’m the only one who sees it happen.”

Katsuki groaned, and Izuku’s eyes widened when he finally caught on, staring at Katsuki in disbelief.

“Kacchan, what are you talking about? You were the first.”

“I was what?”

“The first,” Izuku repeated, grinning. “You thought I never heard you sing? You were upset by that?”

“Shut up.”

“You sang to me during the fight,” Izuku giggled. “I thought I was hallucinating, or it was like… Some weird dying-moment thing. Or at least a concussion. We were in the middle of a fight, I just got thrown through a wall, and you started singing. And the villain was dancing with you, I had no idea what was going on, it was insane.”

“What did I sing?”

“I don’t know the name, but it was low, and slow, and sappy as hell.” Izuku ducked when Katsuki swiped at him, still grinning from ear to ear. “You were serenading me, Kacchan. All full of regret about we were meant to be together forever, but the villain was trying to ruin that. I’m pretty sure you called us a fairytale at one point.”

“I did not.”

“Oh, Kacchan, you absolutely did. You sang all about how despite everything we’ve been through, you still believed that the two of us were meant to be together forever. You can’t take that away from me.”

“We are.”

“What?”

“We are meant to be together. Forever. How could we not be? But I did not sing that sappy bullshit.”

“You really think so?”

“Haah? You don’t?”

“Of course I do!” Izuku interjected quickly, before Katsuki could get riled up. “But I didn’t know you did!”

“Ugh.”

Katsuki looked away, and Izuku’s smile softened as he watched the little blush rush to his pouty cheeks.

“You sang twice,” Izuku said quietly. “You’re the only one who sang twice.”

“Was the second one just as bad?”

“Yeah,” Izuku giggled. “It was. Maybe worse.”

“Oh god,” Katsuki groaned, dropping into a chair and burying his face in his hands. “I’m never gonna live this shit down.”

“It’s okay Kacchan, I’m the only one who knows about it!”

“You said you told Round-Face and Glasses about all this shit.”

“I did, but I… Left yours out,” he admitted sheepishly. “I don’t know, it felt personal, and I knew you wouldn’t want them to know.”

“Really?”

“Yeah.”

“Um, thanks.”

Izuku sat down beside him, reaching for his hand, and to his delight the strong fingers didn’t hesitate to lace with his. He’d spent most of his life offering his hand to Katsuki, and it was still rare for him to actually take it – being able to hold it so casually was like a dream come true.

“Do you want to hear about it?” Izuku whispered. “I won’t say anything, if you don’t.”

“Get it over with.”

“You were in my kitchen, cooking for me, in that sweet, caring way you always do when I’m hurt or sick.”

Katsuki’s eyebrows knitted together, but he didn’t speak, so Izuku continued happily.

“You told me how you wanted to help solve all my problems, and you wanted to grow old with me, and how you wanted me to love you – wanted to have my whole heart. And I told you that you already did, even though you couldn’t hear me. I told you you’d had my heart for a long, long time. And we danced together, and I maybe cried a little bit, and when it was all over-”

“You told me you loved me.”

“Yeah,” Izuku smiled. “I’m sorry, it must have been really out of the blue, for you.”

“Like I fuckin’ care,” Katsuki snorted. “You know how damn long I’d been waiting to hear those words?”

“I love you.”

“I love you too, you damn nerd,” Katsuki huffed, ruffling Izuku’s hair. “Even if you cheated your confession.”

“I did not!”

“You did. Only did it because of a stupid karaoke quirk.”

“It’s not my fault you were too emotionally constipated to tell me yourself.”

Katsuki’s eyes narrowed, but he didn’t try to argue – he was at least self-aware enough to recognise that minor shortcoming in himself.

“It’s gonna be hard, when the quirk wears off,” he mumbled after a moment. “I won’t be able to help you cheat anymore.”

“Then we’ll just have to learn to do it properly.”

“You’re gonna make me learn to say all that shit?” Katsuki grimaced. “You know I’m shitty at putting that crap into words.”

“Well, that’s a problem for next week,” Izuku smiled faintly. “For today… Maybe you can just try thinking it, for me. Thinking really, really hard.”

Their eyes met, and Katsuki fell silent, a crease forming in his forehead as he concentrated. The look on his face was a little unnerving, in all honesty, but Izuku didn’t dare to say it – his Kacchan was trying so hard, just for him, after all.

Izuku jumped when Katsuki thumped his hand on the table, expecting frustration or annoyance, but then it happened again, and again, and… He almost didn’t believe it, when his ears filled with a soft melody. Katsuki’s silky voice rang through the apartment as he stood up sharply, towering over Izuku. He looked down with a new expression on his face, one Izuku had never seen in all their years of knowing each other, and there was something strangely exciting about unlocking something new in Katsuki.

He pulled Izuku’s chair away from the table as he sang, giving himself room to walk slowly around him, sharp red eyes bearing down on him the entire way. Izuku craned his neck to watch, feeling the slow, steady beat of Katsuki’s footsteps on the floorboards, and deep in his stomach, something flipped. When he reached the front again he gripped Izuku’s chin in his hand, tilting his head back until their eyes met, and Izuku swallowed hard. It wasn’t fair, how attractive Katsuki looked like this. He was so sexy, so sure of himself, and Izuku realised far too late that he hadn’t paid a moment of attention to the words that supposedly came from deep down in Katsuki’s heart.

Shut your mouth. Charming. And very typical. Maybe Katsuki was more annoyed about the love songs than he thought.

The thought was gone in an instant when Katsuki slid a hand up his own shirt, giving Izuku a glimpse of taut abs that he never wanted to tear his gaze away from, and his eyes widened as Katsuki tore it over his head, throwing it aside. He stepped closer, almost straddling Izuku’s lap, and Izuku’s eyes raked up a little higher, to the sculpted pecs that gave Katsuki such a thick, pert, soft chest.

A single finger trailed up Izuku’s throat, sending a shiver up his spine, and then his gaze was being dragged upward, up to find the sharp-toothed smirk that waited on Katsuki’s lips, always so cool and confident. Further still, his gaze slowly rose, to meet red eyes still full of that expression Izuku had never seen before.

Hunger.

Izuku’s hand twitched toward him, and Katsuki grabbed it without hesitation, bringing it in to rest on his waist. He reached for the other one, then, and brought it to his chest, letting Izuku roam his soft skin with greedy hands that just wanted to pinch and squeeze and grab. He managed to contain himself only because Katsuki stepped in closer again, rolling his hips in Izuku’s lap, and it took all Izuku’s focus to bite back a long, low moan. He pulled Katsuki down into his lap, easily supporting his weight just to get him closer, to slide his hands around to a smooth back and curl his fingers into claws against it. His nails traced long, shallow grooves, radiating out from Katsuki’s spine, and he shivered again when Katsuki’s voice dropped low, singing right beside his ear.

Izuku understood, then. Katsuki was not, after all, a patient man.

Sharp teeth nipped at his skin, making him jump so hard he thought he might knock Katsuki off his lap, but Katsuki just kept up that predatory smirk and reached for his crotch, locking eyes with Izuku as he popped his button open. The zip slid down in what felt like slow motion, taking an eternity to fall open on dark boxers, and Izuku’s hand moved immediately to slide through the gap.

Katsuki shed his trousers without hesitation, letting them fall off his legs to puddle on the floor, and Izuku moaned when he felt the solid bulge cupped in his hand, twitching eagerly in his grip. When a hot mouth sucked and licked the side of his neck he damn near came in his pants, moaning unabashedly and arching to give him more room.

Katsuki stood, then, giving Izuku a clear view of every defined muscle, every sexy scar, every curve and angle and rise and dip. He knew, too, that Izuku was looking – that much was evident by the way he stood tall rather than his usual slouch, shoulders back and chin up, fingers toying with his underwear teasingly. He tilted his head to one side, showing off the long neck that Izuku so desperately wanted to mar with bruises, and those smouldering eyes seemed to look straight through him, as if he were the one seeing Izuku’s deepest thoughts and desires instead of the other way around. Then again, it didn’t take a genius – or a weird quirk, for that matter – to notice the way Izuku’s pants had become uncomfortably tight in the crotch, or the way he squirmed in his seat to try to take some of the pressure off.

Katsuki turned away, still singing in that clear, smooth tone, the same steady rhythm pounded out against the floor under his heel. Izuku whined to himself at the loss of his view, the gorgeous face turned away, and with it, the greatest abs and pecs in the world. In return for his sacrifice, though, he got a strong, toned back that flexed as Katsuki moved, and a cute little butt that looked ripe for a good spanking. The arms, the thighs, the slim waist that Izuku longed to wrap his hands around – it was all there, just for him, and not even Katsuki was trying to stop him from staring. If there was one good thing that had come out of the stupid quirk, it was that moment, where Katsuki swayed his hips and hooked his thumbs under his waistband, slowly inching the dark boxers lower, lower…

Izuku’s breath shuddered, and for a moment he bent over, his head spinning like he might pass out right there on the dining room floor. As soon as he regained his composure he shot back up again, ready to watch, and…

“Earth to nerd,” Katsuki cut in, waving a hand in front of his face. “Anything?”

Izuku’s eyes shot open, lower lip trembling when he saw the clean, clear floors, the fully-clothed Katsuki frowning at him pointedly, as if he’d just zoned out into a daydream for a moment.

“Fuck this quirk,” he hissed, jumping up so quickly that he almost knocked his chair over in the process. “Should call the shitty thing blue balls in quirk form or- Fuck this.”

He yanked Katsuki out of his chair, tearing the old t-shirt away from his body like it was made of newspaper, not thick fabric that was supposed to be durable. Katsuki could only stare in awe as Izuku grabbed him around the waist, pulling him in for a hot, messy kiss as he shoved pants and boxers alike down to their ankles. Before Katsuki could even fully register what was going on, their bodies were bare-ass naked, wrapped around each other like it was second nature, like they’d done this every day of their lives instead of never before. Katsuki didn’t dare question it, refused to risk ruining it, and instead just gave as good as he got in the desperate twining of their tongues.

“I need you,” Izuku whispered, when they parted for a second to breathe. “I want to fuck you so bad, Kacchan.”

Katsuki’s stomach filled with butterflies, and he nodded hurriedly, before he could accidentally do anything to suggest he was anything less than eager-as-hell. Izuku’s lips crept into a smile, his hands sliding up Katsuki’s spine to press their torsos tighter together, and Katsuki nodded once more, a little more firmly this time.

“Fuck me,” he choked out. “Deku. Izuku. Fuck me.”

Izuku picked him up like he weighed nothing at all, throwing him at the bed before Katsuki even realised they were out of the living area. Immediately Izuku was looming over him on the mattress, running his hands down the pecs he’d spent so long staring at and giving them a quick squeeze.

“You’re so hot, Kacchan,” Izuku hissed. “Fuck, you’re killing me.”

Katsuki just spread his legs a little wider, letting Izuku fall between them, and Izuku moaned like it physically pained him to watch. He fumbled in the drawer beside his bed, digging out an old bottle of lube, and Katsuki did his best to take long, deep breaths as he felt the moment drawing closer.

“I’m gonna take good care of you, Kacchan,” Izuku promised, pressing a kiss to Katsuki’s lips, then trailing them down his body. “You’re gonna be real good for me, aren’t you? Gonna lie back and relax and let me fuck your brains out.”

“Is that what you want?” Katsuki smirked. “For me to be good for you?”

“Fuck that sounds hot,” Izuku huffed a short laugh. “I want to make you feel good, Kacchan. Want to make you remember this night for the rest of your life. And if you ever leave me, ever try this with someone else, I want you to remember how mind-blowing tonight was and realise I’ve ruined you for everyone else.”

“I’m not going anywhere. Now or ever.”

“Good,” Izuku grinned, pressing a sweet kiss to Katsuki’s inner thigh, “But I still want to blow your mind.”

“Just my mind?” Katsuki smirked, wiggling his hips a little in a way he knew Izuku would later call adorable. “I can think of something else you could blow, for me.”

“Well then, you’ll have to be a very good boy, won’t you?”

Katsuki’s smirk stretched even wider, but before he could come up with a retort he felt a finger breaching his rim, so gentle and careful despite the impatience they had in common. He pressed kisses all over Katsuki’s stomach and crotch, took little nips at bits of tender skin, and Katsuki’s chest heaved as the finger slowly slid deeper and deeper, until he could feel it filling him up. For a minute it just stayed there, gently stroking as Izuku licked a trail up Katsuki’s rock-hard cock, but when it began to shift in and out, making gentle thrusts, he knew he wasn’t going to be able to wait for long.

“I need to cum,” he said urgently, reaching for his dick and whining when Izuku caught his hand before it got there. “Deku, please.”

“It’s a good thing we’re still young,” Izuku teased, admiring the faint blush on Katsuki’s cheeks. “You can handle more than once?”

“Fuck yes.”

“Okay, Kacchan. Cum for me, show me how good it feels.”

He licked across the tip of Katsuki’s cock, wrapping his lips around just the head, and before he could even suck or lick some more, Katsuki was filling his mouth with fluid. The taste was bitter, salty, and Izuku pulled a face as he swallowed it down valiantly, not easing up for a moment on the finger in Katsuki’s ass.

“So hot,” Katsuki mumbled, face burning.

“What is, Kacchan?”

“You. Swallowing my cum. Fuckin’ hot.”

Izuku smiled, much brighter than the smirks he’d been wearing, and Katsuki’s stomach swirled when he saw it. As hot as the smirks were, this was the Izuku he’d fallen in love with so many years ago.

“Relax for me, Kacchan. I’m gonna make you feel even better.”

“Yeah?” Katsuki snorted, getting comfortable all the same. “Show me, nerd.”

Izuku responded by sliding a second finger in, filling Katsuki up until he felt like he might burst, but aided by plenty of lube they slid smoothly in and out, and Katsuki lost a moan when he felt them hit the sweet spot.

“There,” he hissed, throwing his head back. “Do that again.”

“Here?”

“Fuck!”

“Yep, there,” Izuku grinned. “Relax.”

It was hard this time, with the way his lungs struggled to hold air and every muscle in his body seemed to want to arch and stretch in the search for more, but Katsuki did his best to let Izuku take control, to show him exactly how much he trusted the nerd, even if he couldn’t say the words.

“Love you,” he choked out.

“I love you too,” Izuku beamed, rewarding him with another long lick that somehow hurt but in the best way possible. “Such a good boy for me, Kacchan.”

Katsuki nodded frantically, and Izuku couldn’t help but giggle, finally slipping a third finger into the hole to stretch him out nice and wide. He knew when Katsuki could comfortably take three of Izuku’s thick, gnarled fingers, he should finally be ready for Izuku to fuck him for real, and Izuku’s dick twitched and leaked just at the hint of getting closer.

Judging by the way Katsuki arched his back and clutched at the sheets, Izuku was pretty sure he was eager for it, too. He was so pretty, all flushed and sweaty with his eyes squeezed shut, head thrown back to show off his pale neck. Izuku shifted his weight, making shallow little thrusts with his hand as he moved, and bit down lightly on the side of Katsuki’s neck. He sucked lightly, and Katsuki’s breath hitched, head turning away so Izuku almost missed the little blush that grew brighter on his cheeks. He sucked a little harder, teeth digging a little deeper into the skin, only letting go when Katsuki finally lost a breathy moan. A red spot bloomed where his mouth had been, and Izuku caressed it with his tongue, lapping across the mark and trailing kisses down toward his throat.

“Kacchan?” he whispered, feeling Katsuki shiver beneath him. “Does it hurt?”

“No,” Katsuki answered quickly, his voice trembling. “Fuck me.”

“You sure? I don’t want to rush into this and hurt you.”

“If you don’t fuck me right now I’m gonna do it my damn self.”

Izuku laughed, but he shifted again obediently, moving back down between Katsuki’s legs. He slid his hand all the way out this time, smiling when Katsuki whined at the loss, but even with everything else distracting him, he didn’t miss the way Katsuki’s eyes cracked open to watch when he opened the lube again.

“I love you, Kacchan.”

“Yeah, yeah,” he grumbled, huffing quietly. “Stick your damn dick in me, you sappy nerd.”

“I’m gonna fuck you lovingly,” Izuku teased. “You’re gonna be a good boy for me and just get nice and relaxed while I take good care of you.”

“Just fuck me hard and fast until I can’t walk.”

“I can do both.”

Katsuki hissed, muttering something Izuku didn’t quite catch, and with a grin Izuku ran a hand along his rock-hard dick, spreading a generous amount of lube along his shaft. Katsuki shifted his hips, spreading his legs a little wider, and Izuku caressed one of the thick thighs as he lifted it onto his knee. The leg curled around his waist without hesitation, holding on tight, and finally Izuku found himself lined up, itching to get inside the warm, wet hole.

To his surprise, Katsuki didn’t say a word – didn’t cuss him out or tell him to hurry his ass up, didn’t make crude jokes or hurl half-hearted insults – he just waited, head cradled by Izuku’s pillow, staring straight into Izuku’s eyes.

“I love you,” he murmured, when Izuku smiled at him. “Sorry.”

“It’s okay,” Izuku assured him, smile stretching wider. “I love you too, Kacchan. I’m so glad it’s you.”

With one hand around his dick to guide it, he finally pushed through into the warmth of Katsuki’s body, gasping when the hole tightened around him immediately. He tried to slow down, to let Katsuki relax again, but Katsuki was already glaring at him the moment he began, leg pulling pointedly at Izuku’s back. With a little nod, Izuku continued at a steady pace, moaning when he managed to get all the way down to the base.

Katsuki’s other leg rose to wrap around him, pulling at him desperately, and it took everything in Izuku to not laugh at the desperation. He appreciated it, really – it might have been the best thing he’d ever felt, knowing Katsuki wanted him so badly – but he knew if he went wild like Katsuki wanted, they’d both just end up ruined the next day. Considering his mornings were still a little achy as it was, he didn’t really want to add sex-injuries to the list.

When Katsuki began to relax around him, to adjust to his size and shape a little better, Izuku gently began to slide back out. Katsuki whined at him again, much louder this time, and Izuku smiled faintly when the legs fought to keep him there.

“Does it hurt, Kacchan?”

“Fuck no!” he grimaced. “I want you in me.”

“You don’t want… This?”

Izuku jerked his hips, thrusting back in quickly, and even though he only moved a few centimetres, it set off a new round of moans. This time it wasn’t only Katsuki who loosed them, an equally loud moan falling from Izuku’s lips, the sounds mixing into an erotic symphony around them. It had the desired effect, though, Katsuki’s legs loosening enough for him to start pulling out again, thighs trembling around him with the effort it took to resist. Izuku picked them up, levering them up to his shoulders instead, and Katsuki blushed again but allowed it. With his knees up, Izuku had far more room to move and control his pace, and judging by the way heels already dug into his back, he suspected it gave Katsuki the freedom to hold on, too.

When just the head of his cock was left inside, he thrust forward again sharply, all the air evacuating his lungs when he bottomed out. Nothing else compared to that feeling – no hand or toy or anything else could come close to as good as Kacchan felt. His heart pounded so hard he was sure Katsuki had to be hearing it, and he gasped as he struggled through laboured breaths, but he continued to thrust in and out, picking up his pace a little, watching Katsuki writhe beneath him and feeling strong legs attempt to crush his shoulders, as he searched frantically for more. This time, Izuku was more than happy to oblige. They’d found their position, adjusted to each other’s body and how to fit together, and the overwhelming pleasure seemed to be drowning out any concerns Izuku had. He was no longer worrying about doing it right or making it perfect, all he needed was the slick slide of his cock through Katsuki’s twitching hole.

“Deku,” Katsuki choked out, his voice catching in his throat. “Touch me.”

Izuku knew it was meant to be a demand, but it came out more like a plea, and Izuku wasn’t sure he’d ever heard that tone in Katsuki’s voice before.

“Say it again. Tell me what you want.”

“Touch me. Fuck me. Let me cum.”

“You’re such a good boy,” Izuku said breathlessly, picking up his pace again and reaching for Katsuki’s cock. “So proud of you. You can cum, Kacchan, you’re so good.”

It only took two strokes of Izuku’s hand for Katsuki to let it all out, staining his chest and stomach with semen, and the tired, spent look he shot Izuku’s way was almost enough to tip him over the edge on its own. The heavy eyelids, peering out at him through long eyelashes, the jaw hanging open slightly as he struggled to get his air back – Katsuki was just too beautiful.

Another good thrust, and Katsuki clenching down on him in turn, was enough to make Izuku join him. Hot fluid filled Katsuki’s ass, leaking out around them on the bedsheets, and Katsuki just watched with that same expression as it happened, watching his every move. His legs tightened though, once more, holding Izuku in close as he shot the last of his load, keeping him inside even as he quickly began to soften.

“Kacchan,” he croaked. “That was the best thing I’ve ever done in my life.”

“Too much talking,” Katsuki grumbled, releasing Izuku and letting him slide out. “Nap.”

“We’re a mess.”

“Don’t care.”

Izuku tenderly lifted Katsuki’s legs off his shoulders, setting them down on the mattress, and the moment he was free Katsuki was rolling onto his side, wrapping his arms around a spare pillow and nestling in to sleep.

“Kacchan, I need to change the sheets,” Izuku protested, smiling all the same. “You’re adorable, but really.”

“Not moving,” Katsuki murmured into the pillow. “Deal with it.”

Sighing, Izuku climbed carefully to his feet and found his balance, making sure he was rock-steady before he slipped his arms under Katsuki’s frame and gently lifted him off the bed.

“Oi, fucker!” Katsuki protested, tensing up immediately. “Put me down, asshole!”

Izuku laughed, but ignored the demand, carrying him carefully through to the bathroom before he finally set him down. Katsuki glared at him, throwing the pillow away pointedly, but he sat silently on the little stool and let Izuku bathe him with more tenderness than he thought he’d felt in his life. He cleaned off sweat and cum, leaving kisses in his wake, even lathered up his hair with a familiar smelling shampoo and conditioner.

“Stay right there,” Izuku instructed, when they were both cleaned and rinsed. “You get dry, I’m gonna go change the sheets.”

“I’ll do it,”

“I said stay put,” Izuku grinned, kissing his cheek and watching him blush. “Dry your hair so you don’t drench me in bed.”

Katsuki grumbled something unintelligible, but nodded all the same, accepting a clean towel to squeeze at his hair with.

Izuku pulled a face as he cleared off the bed, throwing everything straight into the laundry machine down the hall. Fresh sheets from the closet went on, and he retrieved the spare pillow from outside the bathroom, fluffing both pillows and setting them in place for the pair to snuggle.

Katsuki stood when Izuku returned to the bathroom, wincing before he made it even halfway up, and immediately Izuku’s arms were around him, holding him steady. The protests were a little less convincing this time, as Izuku carted him back to the bedroom and found him some fluffy pyjamas, and Izuku couldn’t help but smile at how pitiful the complaints had become.

“Can we cuddle, Kacchan?” he asked, batting his eyelashes in what he hoped was a cute way, “Since you’re staying over?”

“Oh, am I, now?” Katsuki snorted, shuffling over all the same to lie straight down the middle of the mattress. “I don’t remember agreeing to that.”

“Too bad,” Izuku grinned back, sliding in behind him and wrapping him in a hug. “I’m sleepy, Kacchan. Cuddle with me.”

“Whatever. I guess.”

Despite pretending to be reluctant, Katsuki clung to him the moment they were in place under the blankets, burying his face in Izuku’s chest and sighing contentedly. Izuku pretended not to notice, for his sake, but as he curled up and closed his eyes, he couldn’t wipe the smile off his face.

“The world feels so quiet,” Izuku whispered, when the apartment fell silent around them. “I’m kind of sad that I’m not gonna catch you singing me love songs much longer.”

Katsuki didn’t respond, and for a moment Izuku wondered if he was already asleep, but then he shifted slightly, bringing his head up to rest his cheek on Izuku’s shoulder.

In the dark, quiet room, so softly that even someone in the next room would likely have missed it, Katsuki sang.
