Sharing Rooms [NSFW]

Katsuki slumped in his seat, huffing quietly when he saw the excited, freckled face heading toward him. He’d moved to the little lounge area to avoid people, though he supposed it wasn’t like Izuku knew that. The couches were comfortable, though, and he’d found an old fantasy novel that looked interesting, so it wasn’t like he was gonna just walk away or something. Maybe if it had been... He wasn’t even sure. There was probably someone in his life who he’d have abandoned his comfort and his book to avoid, but he couldn’t think of one off the top of his head, least of all Izuku.

“Long time no see!” Izuku said, with a giggle that Katsuki hadn’t heard in a long time. “What are you doing up here?”

“Fuckin’ shared rooms,” Katsuki grunted, and Izuku hummed his sympathies – he didn’t need to say more than that, for Izuku to understand.

“Want me to leave you alone?” Izuku offered, dithering at the edge of the seating area, ready to move on if Katsuki so much as hinted at the words.

“S’fine,” Katsuki admitted. “Been a while, like you said.”

“I was kidding; I saw you this morning. Did you forget so quickly?!”

“It was a joke, nerd.”

“Oh! Sorry, you’re too good at the straight-faced thing.”

Katsuki shook his head faintly, and Izuku flopped onto the couch opposite him, gesturing with the worn manga in his hand.

“I heard they had a little library here and thought I should support it,” Izuku explained, even though Katsuki hadn’t gotten around to asking yet. “More places need libraries.”

“Everything should be a library.”

“What about... the gym?”

“You kidding me? Fuck yeah. Borrow a book to read on the treadmill?”

“Bench press?”

“Put a book holder on the bar.”

“Okay,” Izuku said, grinning. “Then what about... a nightclub?”

Katsuki just looked at him, and Izuku laughed brightly.

“Okay, okay, maybe some people would want that,” he acknowledged. “Most people go to clubs for a very different vibe than a library!”

“Fuck most people.”

“That sounds like a tall order, but I guess a nightclub would be the place to start.”

“Gross.”

Izuku was clearly amused by that sentiment, and Katsuki knew exactly why. He wouldn’t say it out loud, obviously, but he’d heard a lot of stories about Izuku’s exploits over the years. He’d run out of friends to fool around with far too quickly, and had moved on to random one-time things with people who hopefully didn’t recognise him.

“Okay, what about public toilets? The books would get gross and germy.”

“Staple pages to the stall doors or above the urinals. Hands-free.”

“What if people splash?”

“I think I just threw up a little in my mouth.”

“Then I win!”

“Fuck no. Put plastic over them or something.”

“Ugh. Restaurants, then!”

“Some people dine alone, nerd.”

“Damn it! Alright, fine, you win this time, but I’m pretty sure you need to stop calling me a nerd.”

Katsuki grimaced, but Izuku wasn’t exactly wrong. Well, he was a little wrong – Izuku was still a damn nerd, after all – but he probably needed to stop calling it out, if he was gonna complain about the world needing more libraries.

“Can I read with you?” Izuku asked, already settling in and getting comfy. Katsuki would have sent him away long ago, if he really wanted to, and Izuku knew it.

“Knock yourself out.”

There was something peaceful about hanging out with Izuku, something weirdly calming about his presence. He supposed when you’d known someone for literal decades, there was a comfort that came with being around them. Then again, Katsuki had been thrown in with Eijirou and Denki, who he’d also known for over a decade, and even though he appreciated that the agency had at least put him with his friends rather than someone random, it had still been a nightmare so far. He grimaced again at the thought of going back there. They were his friends, sure, but fuck, when he was trying to sleep? Not a good combo.

“Shouto ate something exotic in a back-alley restaurant, earlier,” Izuku said quietly, without looking up from his book. “I love that he’s gotten adventurous about trying new foods and things, it makes him happy and that makes me happy, but when you’re rooming together, it’s not a great combination.”

“Why?”

“He’s stuck in the bathroom.”

“Oh.”

Izuku chuckled, but it came out a little pained.

“He’s gonna be fine,” Izuku said. “I don’t need to rush him to a hospital or anything like that, but he’s... you know. Getting a lot of use out of the fancy bidet.”

“Gross.”

“Tell me about it,” Izuku snorted.

They fell silent again for a little while, flipping through their pages contentedly. Considering they’d really only been in the hotel to sleep so far, Katsuki hadn’t really tried out many of the buttons on the toilet, but suddenly he was kind of curious about what exactly made Izuku call it fancy. Did Izuku just have insanely low standards from his shitty on-campus apartment, or was Katsuki missing out on something? He was tempted to ask, but he couldn’t quite get the words out, couldn’t bring himself to break the peace.

Besides, it sounded like Shouto was the expert on it, so maybe he was better off keeping that question for later, when he could torment the hell out of him with it.

Katsuki sneaked a glance up, finding a soft smile on Izuku’s face as he flipped through pages. Katsuki was pretty sure Izuku had read the same volume about a thousand times – he only knew it was a different copy because it was so much more beat-up than any of Izuku’s books. There was a good reason that Izuku had been the only one allowed to borrow Katsuki’s books when they were younger, after all. He took care of shit.

“It’s okay when it’s for one night,” Katsuki said quietly, when Izuku caught him looking. “The rooms. It’s not great, but it’s bearable.”

“But a week is too much,” Izuku agreed. “Sometimes I just want to walk around with no pants on, you know?”

“Fuck yes. I wanna walk around barefoot without a couple of idiots yelling ‘for free?!’ at me.”

“I always feel like I have to make conversation,” Izuku said, valiantly holding back a giggle that Katsuki knew was trying to get out. “Like on my own I can just sit in silence happily, but when there are other people in the room, it feels awkward to not talk.”

“I wanna use the toilet without someone listening in.”

“Now you understand my pain with Shouto.”

Katsuki snorted, looking away before he opened his mouth again.

“And jerk off.”

“Gosh yes,” Izuku sighed. “Grown adults put in a room where they can’t masturbate or have sex for at least a week?”

“I guess I could talk them into some weird threesome if I got desperate, but no thanks.”

“I dunno, could be fun,” Izuku teased. “Better yet, get them involved in some weird threesome.”

“And make the problem worse?”

“In someone else’s room.”

“Fuck, now we’re talking. You offering?”

Izuku just laughed, and Katsuki narrowed his eyes – the lack of denial was, honestly, a little concerning. Maybe he was dropping hints? Surely he would have just said it outright, though; he knew Katsuki better than that, didn’t he? Not to mention, he wouldn’t go through Katsuki to make plans to fuck his best friends, he was better than that. And if he’d really wanted it, he’d have just gone down there when he saw Katsuki reading. No, hinting definitely didn’t make sense.

“Been there, done that,” Izuku said, when he caught Katsuki tensing up. “I mean! Not the weird threesome part, shit, I phrased that so badly. But— You know. Kirishima and Kaminari. Not at the same time, don’t look at me like that.”

Katsuki grimaced, but nodded faintly, looking back down at his book.

“I figured,” he said finally. “I mean, I heard one of them, and the other... Well, you’re not the only one with a reputation.”

“Anyone would think you were jealous, talking like that,” Izuku teased. “I didn’t know you were that pent up.”

Katsuki flipped him off, extra frustrated by his lack of materials to throw. It wasn’t like he was gonna throw a book at him, after all; it might hurt the book. But Izuku gave him an apologetic smile, even though they both knew he wasn’t actually apologetic about it, and Katsuki decided to let it go, just that once. Mostly because he had a good book in his hands, and it was hard to get genuinely mad when he was in a library, no matter how small.

“I forgot how peaceful you get around books,” Izuku said, throwing his hands up in surrender when Katsuki glared at him again. “It’s a good thing! I’m not teasing or anything! It’s nice to see you relax, sometimes!”

“Whatever.”

“I’m just glad you still have something like that in your life,” Izuku explained. “Life has been so stressful, especially lately, and you don’t seem to ever take a damn break, so I don’t know how you stay upright some days.”

In all honesty, Katsuki’s life had felt easier lately, since he’d started working with Izuku again. He was no longer wracking up massive amounts of overtime fuelled by way-too-much caffeine, he knew there was someone around to cover his back if he needed it – not that he ever did – and he finally had some motivation again to work his way up the charts, to try to finally make himself the indisputable number one. Life had been... surprisingly good. He’d even been meeting up with his friends occasionally, to grab coffee or dinner, where for the longest time, that had felt like a waste of precious work time.

“It was important to me,” Katsuki said softly. “It didn’t feel as difficult as it probably should have.”

“Thank you,” Izuku said knowingly. “I hope you know I appreciate it all.”

“Are you finally ready to be my sidekick to repay me?”

“No!” Izuku protested, laughing all the same. “I told you: I like teaching, I want to do both, and I am doing both, and I love it! If I was your sidekick, I’d never get time to teach! You’d make me work insane hours with you every single day!”

Katsuki just huffed, and Izuku smiled softly, a slightly wistful look in his eyes that he quickly hid away. Despite his words, Katsuki knew what he really wanted was to fight for number one with everything he had, and teaching was always getting in the way of that. He wasn’t lying when he said he loved teaching, everyone could tell that just from the way he talked about his classes and his students with such enthusiasm, but Katsuki knew it was meant to have been a retirement plan, not a better-part-of-his-life plan. When he’d started, it had been a retirement plan, in a way. Now, though, he was just in too deep, couldn’t take a step back without feeling guilty about it, feeling like he let down too many people who helped him along the way, or who needed his help.

“Besides,” Izuku said, his smile twisting into a little smirk. “You just want me to be your sidekick so I won’t be ahead of you in the charts anymore.”

“Say that to my face, fucker.”

“I just did.”

Katsuki stretched out a leg, just barely long enough to give Izuku a stubborn nudge with his toes, and Izuku laughed as he slapped the foot lightly, pushing it away. Katsuki went right back in, grinning as he dodged Izuku’s cover to get in another shove, and this time Izuku grabbed him, pulling at his ankle and making him slide down the couch, trapping Katsuki’s foot in his elbow and leaning on it like it was the comfiest cushion in the world as he went back to nonchalantly pretending to read his shitty manga.

“Prick,” Katsuki grumbled, setting his book down to brace himself with both hands, yanking his foot back and watching Izuku stumble a little to keep his balance rather than go with it. “Just watch me, nerd.”

“I’m always watching,” Izuku assured him, smiling in a way that almost looked shy. “When have I not been watching you, Kacchan?”

Kacchan. He didn’t hear that name often, these days, and weirdly, he’d kind of missed it; missed being part of a package deal, Kacchan-and-Deku, instead of all this weird Dynamight and Midoriya-sensei shit that just proved how damn old they were getting.

“Get a new book,” Katsuki complained, tucking his feet up underneath himself. “Why do you always read the same thing over and over? It’s not like the ending is gonna change.”

“It’s comforting,” Izuku said, running his thumb down the page lightly, his touch reverent. “Like coming home after a trip, or hanging out with an old friend. ‘It’s not the same river’ and all that, you know?”

Katsuki huffed quietly, but he didn’t bother to object. It wasn’t like he actually had a problem with it, the nerd could do whatever he wanted, but he did sometimes wonder...

“I’m gonna grab a drink,” Katsuki said, setting his book down and gesturing toward the vending machines. “What do you want? A shitty melon soda?”

“Yeah,” Izuku agreed, flashing him a bright smile. “Thanks, Kacchan.”

—————

“You’d think these agencies would be making enough money to rent us private rooms by now,” Katsuki whispered, earning a little giggle that Izuku tried his best to stifle. “Are you getting paid for this shit, at least?”

“Not until we get the capture,” Izuku lamented. “If we fuck this up, I’m out of luck.”

“Like we’d fuck this up.”

The representative finally wrapped up his little speech, and a staff member from the hotel began handing out keycards, bowing to each of them in turn as she passed them over. Izuku’s eyes widened, and Katsuki looked down to see matching numbers in their hands, pausing a second to just stare at them both, wondering if there’d been some kind of mistake. Obviously he didn’t object to sharing a room with Izuku, but it had never happened before, and he could only wonder if someone had been too much paying attention to them over the past few months. Since their little meet-up in a hotel library, they’d started hanging out again more regularly, snatching a coffee during Izuku’s lunch break, or slipping into a quiet restaurant after Katsuki’s late shifts. It had been nice, honestly, and other than a few snapshots of them that went viral online, bombarded with orange and green hearts, or bomb and broccoli emojis, and people declaring themselves dead over seeing the pair together – so nothing new – no one had really seemed to care, or notice anything had changed. Katsuki was tempted to make a dumb joke about the hotel staff being shippers, but that would mean acknowledging to Izuku that he’d seen that shit, and there was no way in hell he was gonna start that conversation.

Other heroes grouped up to make plans for the night, when the agency representative dismissed them, but Katsuki just headed straight for the elevator, not at all surprised when Izuku remained at his side, lugging his over-stuffed backpack. While some heroes brought along a suitcase for away-work, like Denki or Eijirou, and others packed as light as possible so they only had to carry a backpack, like Katsuki or Shouto, Izuku had somehow become the worst of both worlds: determined to keep it in a backpack, but equally determined to pack it so full that it might explode if you looked at it wrong. Katsuki still vividly remembered a class trip in their final year of high school, when Izuku had bought his mother a single fridge magnet from some little souvenir store they passed, and in trying to fit it into his bag, had managed to cause an avalanche of belongings that rolled away down a street, classmates sprinting after them to help him out. He cracked a smile at the memory, and Izuku glanced over, waiting to see if he’d explain it without prompting.

“Do you still carry six different fascia balls to these things?”

Izuku’s face turned bright pink, and he whined when Katsuki laughed, slapping his hands over his face to try to hide the redness.

“I still bring one,” Izuku admitted, voice muffled by his own hands. “And it lives at the bottom of my bag.”

Katsuki cackled, and Izuku leaned in, shoving him lightly with his side. Katsuki shoved him back gently, as their elevator slowed to a stop. Their floor was empty, and mercifully silent, only their own footsteps tapping on wooden floors bringing any kind of break in the peace.

“A thousand yen says the room only has one bed instead of two,” Izuku said, when they reached the door.

“Why the fuck would it only have one bed?”

Izuku gave him a scathing look, and it took Katsuki a moment to catch on.

“You thought it too,” he said, choking back a laugh. “That she put us together on purpose.”

“Fans are weird.”

Izuku scanned his card at the door, holding it open for Katsuki to go first, to lay eyes on both their beds as he kicked his shoes off in the doorway.

“You lose,” he said triumphantly, though he felt much more relieved than anything else. “Two beds, pay up.”

“Damn, I was so sure.”

Katsuki flopped onto the bed closest the door, sighing contentedly, while Izuku went straight to the window, sighing much less contentedly when he saw the view – or, lack thereof.

“I might have to quit this travel thing,” he admitted, dumping his backpack at the end of his bed and sitting down to unpack it. “I thought I would love it, but I always just wish I was back at home.”

“If you were at home, you’d wish you were here.”

“Maybe,” Izuku conceded. “Green grass.”

“That’s not the— whatever, I know what you mean.”

Katsuki closed his eyes, slinging an arm over his face to block out the overhead lights, and Izuku chuckled softly as he padded across the room, hitting a switch that let out a tiny beep as it turned off the main light.

“Thanks,” he conceded.

“All good,” Izuku assured him.

For a while, the room got quiet. Katsuki was debating taking a nap, but he didn’t think he was tired enough to actually manage it. He was socially exhausted, more than physically. At least lying in the almost-dark helped with that, though. Izuku worked on his backpack, quietly unpacking his belongings to settle in, even though Katsuki hoped the job wouldn’t last long enough to need it. That was probably wishful thinking, though; they never lasted less than a week, these days.

“You can, if you want,” Izuku said softly.

Katsuki didn’t answer. He thought Izuku must have been on the phone, at first, but there was no reply, and he didn’t speak again. So he cracked an eye open, glancing over, finding Izuku pink in the face again as he huddled over his clearly-empty bag.

“Jerk off,” Izuku clarified, his voice wobblier and his face redder than Katsuki had ever seen him before. “I just... last time, you know.”

Katsuki still didn’t answer, but this time, it was because he had no fucking clue what to say.

“You seemed pretty irritated about it last time,” Izuku mumbled, his voice speeding up as he got more and more nervous about it. “And it’s not like I care if you take care of it in our room, I can leave for a bit if you want, just let me know, or honestly, I can just put my headphones on anyway and I probably wouldn’t even notice, so just... you know. For the record, I don’t mind.”

“You don’t have to wear pants,” Katsuki offered in return, drawing a choked laugh out of Izuku.

“Thanks,” he answered, his eyes watery. Katsuki was really starting to think he needed to offer Izuku his psychiatrist’s number, the one who had helped with his anxiety in high school. “Sorry, I know that was probably weird to say.”

“When have you not been weird?” Katsuki asked, huffing a little laugh. “Let’s be real, you’ve probably been waiting years to add my jerk off habits to your notebooks.”

“Kacchan!” Izuku protested, apparently breaking through his embarrassment since his voice finally returned to normal.

“That’s not a no.”

“No!!”

Katsuki grinned, turning his head slightly to see Izuku’s mortification, just for his own amusement.

“I was on that Aomori trip before this,” Katsuki told him quietly. “Spent one night with my parents when I got back, then got the call for this one.”

“Oh man, that one went on forever, didn’t it?” Izuku asked, his gaze turning sympathetic when he looked Katsuki’s way. “You must be exhausted.”

“A bit.”

“I can go out for a bit, give you some peace.”

“You’re fine,” Katsuki assured him. “You’re... quiet and shit. And I’m used to you.”

“You don’t have to worry what I think?”

“Yeah.”

“Me too. With you, I mean. You already know everything you could possibly know about me, I don’t have to worry about doing something stupid or weird.”

“Mm-hm.”

“So uh, you haven’t gotten to jerk off in a couple of weeks, huh?” Izuku asked awkwardly. “I hit the nail on the head.”

“Yep,” Katsuki admitted. “So if you’re making a dumb joke, take it back now, before I get tempted.”

“I wasn’t joking,” Izuku assured him. “Do whatever you want.”

“Yeah?”

“Yeah.”

Katsuki still hesitated, but when Izuku picked up a book and his headphones, he quickly caved. He rummaged around in his backpack until he found a bottle of lube, hastily stashed there in the hopes that he’d manage to get five minutes alone at some point, or find an excuse to take a long shower. Izuku seemed completely unphased by any of it, just settling in on his own bed, propping his pillows up to lean against and getting himself comfortable. Katsuki rolled over onto his side, to at least look away from the nerd, and despite knowing that he really shouldn’t have given in so easily, he unzipped his pants.

Katsuki wasn’t exactly the dating type, he’d always just been inclined to shove a hand down his pants occasionally – okay, more than occasionally – and take care of himself as he needed it, rather than get tangled up in anything messy. Relationships came with too much drama, too much baggage, and as much as he thought it might be nice to let someone else shove a hand in his pants occasionally, or maybe even a little more than that, there was just too much risk that came with it, when your name and face were constantly in a spotlight.

After a few slow strokes, Katsuki fell back onto his back. It had always been his default position, and with his brain focussed on something other than the shared bedroom, for a minute, he’d kind of forgotten why he’d rolled over in the first place. A flash of green caught his eye as he moved, and it didn’t take a genius to spot the head quickly turning away, pretending he hadn’t seen anything. He knew the weird-ass nerd had some ulterior motive in suggesting it, knew that it couldn’t have been as innocent as he made it sound, and he knew that he should shove himself away and stop while he had the chance, but then his mattress was dipping, and Izuku was slowly, hesitantly, moving closer, his eyes locked on Katsuki’s hand as he continued to slowly stroke up and down his dick.

“Sorry,” Izuku whispered, as he lifted one leg over Katsuki’s, straddling his knees. “I swear I wasn’t gonna make it weird.”

“And yet here you are,” Katsuki grunted, a little breathless, though his hand, inexplicably, kept moving. “What, you jealous or something?”

Izuku nodded, swallowing hard, and Katsuki’s grip finally faltered.

“Can I help?”

Katsuki didn’t answer, but when Izuku shuffled a little higher on the bed, his scarred hand reaching out, Katsuki didn’t slap it away. He watched, spellbound, as Izuku replaced Katsuki’s fingers with his own, his hand hot and a little sweaty where Katsuki’s had just been slick with lube.

“I kept thinking about it,” Izuku admitted, his voice still barely more than a whisper. “About what you’d look like, the sounds you’d make.”

“Creep,” Katsuki said, though there was no bite in his tone.

“Yeah,” Izuku chuckled, moving his hand a little bit quicker, since Katsuki didn’t stop him. “I wanted to see your face, see what you look like when you come.”

“Better fuckin’ work harder then, nerd.”

Izuku cracked a smile, but he began stroking for real, and Katsuki tipped his head back, gasping when the rough thumb ran across his tip.

“Has anyone else touched you?” Izuku asked, his voice low and oddly a little menacing.

“Fuck off,” Katsuki said breathlessly, face burning. “Who’s got time for that?”

“Good,” Izuku answered, the tone gone in an instant. “I wanted to be the first.”

“All the shitty extras weren’t good enough for you?” Katsuki sneered.

“Nope,” Izuku confirmed, taking Katsuki’s lube bottle to add a little more to the mix. “I tried damn hard to find someone who’d stop me thinking about you, and years later, it still hasn't happened.”

“You talk to all your fuck-buddies like that?”

“Just Kacchan,” Izuku promised.

A hand touched Katsuki’s hip, and then his pants were sliding down, carefully worked over each foot until Izuku could cast them aside. Izuku moved a little closer, and Katsuki could see him hovering, could see the hunger in his eyes as he loomed over Katsuki, eyes raking over every bit of exposed skin.

“Shirt,” he instructed, and Katsuki obeyed, wiggling a little to get it out from under him and strip it over his head. “God, Kacchan, you look so good.”

Katsuki was proud of his body; he’d worked hard his entire life to build it, to get strong enough to use his quirk at full capacity, to eat all the right nutrients to keep himself healthy. He’d never been shy about being shirtless, spent half his life at least sleeveless, and the few times he’d been to an onsen with his classmates or colleagues, he’d never really stopped to think maybe he should be awkward or embarrassed or something. But as he lay there, bare but for his socks, on a hotel bed, with a fully-clothed Izuku looming over him, he suddenly felt oddly exposed, like he needed to cover himself up so that gaze couldn’t continue to look right into his soul.

“This is weird,” Katsuki said, watching Izuku flinch, his hand halting. “Take my socks off, not just my pants.”

Izuku paused, then cracked a smile, reaching back to find them and help Katsuki shed his foot prisons.

“And take your damn shirt off or something, would you?” Katsuki continued. “You’re making it weird.”

Once again, Izuku obeyed, releasing Katsuki just for a moment so he could toss aside his baggy t-shirt.

“I’ve never done shit with someone else,” Katsuki admitted. “So show me what the big deal is. Show me why you fucked every single one of our classmates, and half the other students in the school who I never even met, not to mention our coworkers because I’m pretty sure you’ve fucked most of the top ten at this point, so—”

“Show you what I was practicing for?” Izuku cut him off, grinning. “Sure. The safe word is ‘please’.”

“Asshole, you know I don’t say that.”

“Exactly.”

Katsuki snorted, and Izuku’s grin turned a little sharper as he leaned in, trailing his teeth down the side of Katsuki’s neck. Katsuki squirmed a little, but he didn’t protest, so Izuku bit down gently, catching a piece of skin between his teeth and making Katsuki gasp. A scarred hand splayed across Katsuki’s chest when he squirmed, keeping him pressed into the mattress, and Katsuki finally gave in. His head fell back, his breath shuddered, but then Izuku’s lower hand fell still, left him, and before Katsuki could curse him out for it, it squeezed his head.

“You fucker,” he hissed, trying his best to ignore the low laugh that made his dick twitch in Izuku’s hand again. “What the hell, asshole?”

“I finally got my chance to play with you and you think I’m gonna let it end that quickly?” Izuku teased. “Should’ve given in years ago, then I wouldn’t have to draw this out so much.”

“Given in?” Katsuki grumbled. “You never asked, asshole.”

“Like I didn’t drop enough hints,” Izuku snorted. “You didn’t get it from all the praise and compliments? The way I took every opportunity to touch your arms and chest?”

“No, asshole!”

Izuku froze, leaning back a little to see his flushed face, eyes wide and strangely innocent considering how deep and dark his voice had turned only moments ago.

“Are you serious?” he asked, a grin slowly spreading across his lips. “Kacchan, did you not realise I was flirting with you? For years?”

“Fuck off!”

“Oh my gosh, you didn’t,” Izuku giggled, leaning in again to hide it in Katsuki’s neck. “I’m sorry! I thought it was obvious! I mean, everyone else knew. Most of the people I fucked back then came on to me by starting with ‘I know I’m no Bakugou, but’ so it’s not like I was subtle.”

“Just fucking let me come.”

“Patience, Kacchan!”

“I hate you so much.”

Izuku just grinned again, that cheeky, tormenting look reappearing in his eyes, and Katsuki swallowed hard. In all the times he’d imagined getting someone else to jerk him off, he’d never imagined it like this. Sure, maybe sometimes he’d pictured a hand that was thick with muscle and rough with scars and callouses. And yeah, maybe he’d sometimes imagined a low voice softly moaning Kacchan in his ear. And okay, maybe he’d occasionally seen green eyes shining down at him, all full of tenderness and affection like he always was. But he’d never envisioned that sharp little smirk, that wild look in his eyes that told Katsuki he had plans, and he’d sure as hell never considered the nerd refusing to let him fucking come.

“If you want me to stop, now’s your chance to say so,” Izuku told him softly. “And we’ll never speak of it again.”

Katsuki shook his head.

“Say it, Kacchan.”

“Don’t stop.”

“Okay,” Izuku said, far too triumphantly. “Let me take care of you, then.”

He reached for the discarded lube bottle, and Katsuki breathed a sigh of relief. The nerd had had his fun, he was finally going to stop being a jerk about it, was going to let Katsuki—

His finger stroked across Katsuki’s hole, and Katsuki tensed up. The finger immediately stopped moving, waiting, but Katsuki clamped his mouth shut. Izuku waited, holding his breath, but when Katsuki didn’t speak, he slowly continued moving.

“I know it’s your first time,” Izuku said softly. “But I’ll take good care of you, I promise. Just relax, it’ll feel so good.”

Katsuki nodded faintly, but he didn’t lose any of his tension, so Izuku shifted the hand on his cock, gently stroking him again. It somehow felt torturous, especially knowing there was no way Izuku was actually going to let him come when he clearly had bigger plans in mind, but when warm lips wrapped around the head, a wet tongue swiping across the end, he lost the most embarrassing sound of his life: a long, loud moan that came out rough and jagged, like he didn’t have enough air in his body to get it all out at once. Izuku just moved his tongue again, watching Katsuki intently for another reaction, and Katsuki jammed his mouth shut stubbornly, turning the next one into a muffled whine that was honestly just as bad.

“You’re so pretty like this,” Izuku told him, and Katsuki couldn’t decide which was worse: the words or the fact that he’d stopped sucking Katsuki’s cock to say them. “Let me hear you, Kacchan, you make such good noises.”

“Shut up,” Katsuki hissed, squirming when the finger caressed his ass again. “Just fuckin’ make a decision.”

“A decision?” Izuku asked, smirking. “Kacchan, I’m absolutely gonna fuck you until you can’t walk straight, I just need you to loosen up a little so I can do it.”

Katsuki’s breath hitched, and Izuku leaned in again, taking a long, slow lick up Katsuki’s painfully hard dick.

“How long does it take you to get it back up?” he asked, amused when Katsuki’s cock twitched in response. “More than twenty minutes?”

“Depends,” Katsuki said breathlessly. “How good are you at your fucking job?”

“Three minutes, then,” Izuku said with a smirk. “I can work with that.”

He sank back down on Katsuki’s dick before he could respond, this time going all the way to the base, one hand holding Katsuki’s hips firmly against the mattress as he tried to move, tried to buck up into Izuku’s touch and push himself deeper. This time, Izuku didn’t stop when Katsuki began to leak, didn’t clench down and force it back to make Katsuki suffer, he just moved his head up and down along Katsuki’s shaft, letting Katsuki toss his head from side to side and twist his fingers into the pillowcase to deal with the stimulation. It was adorable, really, the way he couldn’t handle the feeling, but Izuku refused to let up, refused to give him a break. He just kept moving, swallowing hard, until finally Katsuki couldn’t hold it back anymore, shooting his load down Izuku’s throat with impressive force. Izuku slowed his pace a little, but kept moving, dragging out every last little bit of his cum and swallowing it valiantly, eyes locked on Katsuki’s exhausted, scrunched-up face. He really was a pretty thing, even when he was trying his best not to be.

“Fuck,” Katsuki hissed. “Sorry.”

“Don’t be,” Izuku assured him, doing his best to hold back his amusement. “Maybe now you’ll relax a little for me.”

Katsuki finally seemed to catch on, when Izuku reached for the lube again, eyes widening when Izuku gently pushed his thighs aside to create more space. The hand was warm where it slid between his cheeks, coaxing some more lube into the right spot, and this time, despite Katsuki’s thighs tensing again, his fingertip slid inside.

“It’ll feel weird at first,” Izuku told him knowingly. “But we’ll take it slow, so give it a minute, and I promise you’ll like it.”

“You don’t know that,” Katsuki grumbled, turning his head again to avoid Izuku’s gaze. “Some people hate bottoming.”

“Yeah, but I know you,” Izuku chuckled. “Just give me a chance.”

Katsuki nodded faintly, and Izuku pushed his finger a little deeper, pausing again when Katsuki squeezed around him. He took the chance to add a little more lube – better safe than sorry, after all – and shift his free hand to Katsuki’s thigh, caressing the soft, smooth skin that waited there. Still Katsuki remained tense, so Izuku changed tactics, curling his fingers a little and running his nails along the soft skin.

“Fuck,” Katsuki whispered.

“Should’ve known,” Izuku mumbled, shaking his head fondly. “Behave for me, Kacchan. Do I need to give you a spanking and teach you how to be good?”

Katsuki’s breath hitched, his cock already twitching again, and this time, Izuku let himself smirk.

“There’s my good boy, learning how to get it up again for me. Now hold still and let me stretch you, so I can fill you up with my cock and pump you full of cum like you deserve.”

Katsuki’s hand finally left his pillow, in favour of biting down on his knuckle, and Izuku huffed a little laugh at him for it.

“That’s right,” he continued. “You like that, don’t you? Want someone strong to hold you down and fuck you so hard you can’t breathe. No wonder you waited so long, no one else could do it right, no one but me could have you squirming and gasping into your pillow, trying not to cry because I fuck you so damn good. Isn’t that right, Kacchan?”

Katsuki nodded a little, trying so hard to stop himself, and Izuku grinned as he lubed up a second finger.

“I’ve got you,” he promised. “I’ll show you what it feels like to have a hero fucking you.”

Katsuki moaned into his fingers, despite his best efforts, and Izuku took the opportunity to slide the second finger in while he was distracted, feeling him stretch wider around Izuku’s hand. Katsuki squirmed a little, obviously feeling it, so Izuku leaned down again, finding a spot on Katsuki’s neck to suck on, teeth grazing against the skin and making him gasp.

“You’re being such a good boy for me,” he whispered into Katsuki’s shoulder. “I’m gonna fuck you like you deserve.”

He shifted down a little, biting at Katsuki’s nipple this time, making him writhe against the sheets, messing up the hard work some poor underpaid cleaner had put in. When his back arched, Izuku dropped his weight, pinning him in place and getting a whine for it that made him want to screw all the preparation and just fuck Katsuki stupid.

“Next time I’m bringing rope,” Izuku told him, snorting when his dick perked up again.

In a moment of inspiration, he pulled his hand out, watching Katsuki’s eyes open properly to see what was going on. He grabbed a tissue from the hotel box, wiping off his hand, but when Katsuki finally opened his mouth to ask, Izuku responded by curling a hand around his hip, easily turning Katsuki face-down while he was too stunned to stop it. He twisted his torso, trying to see Izuku’s face, but Izuku responded by slapping a hand down on his butt cheek, making a satisfyingly loud sound and leaving a pretty red mark behind.

“Fuck!” Katsuki hissed. “What was that for?!”

“You go where I put you,” Izuku told him, pressing a hand between his shoulder blades and forcing his chest back to the mattress. “Hold still and let me stretch your little hole out before I get impatient and just stretch you on my cock instead.”

Katsuki hissed, but he didn’t object, and when Izuku shifted his hand, pressing Katsuki’s face into the pillow slightly, Katsuki lifted his hips a little, seeking out Izuku’s waiting hand.

“You little whore,” Izuku said, grabbing the lube and squirting it straight onto Katsuki’s ass, rather than move his hand from where it was tangled in blond hair. “You’re just gasping for my cock, aren’t you? You’ve been waiting such a long time to see what a good dick feels like, all these years of yelling and swearing, just waiting to be put in your damn place.”

Katsuki whimpered into his pillow, and Izuku jammed his fingers back in, taking the moment of pliancy to start stretching him a little wider.

“Surprised I even need to stretch you,” he continued, curling his fingers to find the spot that would make Katsuki cry. “Little slut like you? Thought you’d be stuffing yourself full of toys every night, surprised you can even get to sleep without a thick dildo filling you up.”

Katsuki was surprisingly quiet, though Izuku couldn’t help but notice the damp spot forming on the sheets beneath his hips.

“Maybe this is the real reason you have to jerk off so much,” Izuku continued, smirking to himself. “You just need a real fucking to teach you what it’s supposed to feel like, then you’ll be good for a few weeks.”

He finally found the spot he was looking for, making Katsuki gasp into his pillow, and Izuku grinned as he stroked at it with the lightest touch he could manage, just enough to make Katsuki squirm again.

“Hold still,” he demanded, slapping Katsuki’s pale cheek and making it match the first. “I’ll tell you when it’s your turn to come, if I think you’ve earned it.”

Katsuki moaned again, and Izuku knew he’d won. If Katsuki was going to protest or object at some point, that would have been the one, the one where Izuku dared him to be good enough. His lack of complaints was already enough, but that cute little moan at the thought of it? Fuck, Katsuki was gonna be the death of him.

He was finally taking both fingers comfortably, and Izuku found himself contemplating, glancing down at his own cock. Usually he liked to get three in, to make sure it would be comfortable for everyone involved, but it was so damn hard to wait, and Katsuki was so cute and eager, so reactive to the pain. He’d probably like the burn, right? But for his first time...? No, Izuku had to be patient, as much as he felt like he had to be a saint to do it. He slid a third finger in, finding it surprisingly easy now that Katsuki was practically begging for it, his thighs twitching a little wider every time Izuku hit the right spot. To reward him, Izuku moved his free hand back up to Katsuki’s hair, tangling his fingers in it and pulling lightly to make him gasp. He leaned in, bringing his lips to Katsuki’s ear, dropping his voice a little lower when he spoke.

“You ready for the best day of your life?” he asked. “Ready to finally get fucked like the desperate little whore you are?”

Katsuki nodded faintly, eyes squeezed shut, and Izuku pulled a little harder at his hair, stretching his fingers wider inside his hole at the same time.

“Tell me.”

Katsuki was silent. For a moment Izuku was worried he’d gone too far, but then those soft, pink lips parted.

“Fuck me,” he whispered.

“You can do better than that, Kacchan.”

“I want you to fill me up,” he mumbled. “I’ll take it like a... a good little whore. Please.”

Izuku’s dick throbbed, but he paused anyway, hesitating.

“Not the safe word,” Katsuki groaned, his face burning as he tried to hide it in the pillow, halted by Izuku’s hand in his hair. “Izuku, Deku, just fuck me.”

“Safe word is threesome,” Izuku said breathlessly, removing both hands from Katsuki in favour of lubing himself up in a hurry. “Sorry, please was a stupid joke to make.”

“I don’t want apologies, asshole, I want your dick.”

Izuku spanked his ass again, twice in a row this time, then raked nails down his back sharply as he leaned in, his body weight pressing Katsuki into the mattress.

“That’s not how you get what you want, slut,” he hissed, right by Katsuki’s ear. “Behave yourself. Know your place.”

Katsuki groaned, and this time when he turned his head into the pillow, Izuku allowed it, pushing it down lightly just to make a point.

“I can’t wait to feel you,” he said, as he finished lubing up and shoved Katsuki’s thighs into place, getting a good angle to point his perky little pink-cheeked butt at Izuku’s hips. “Gonna feel so good around me, make me come so well.”

He lined himself up, making sure Katsuki was holding still before he began to push himself inside, trying his best to take it slow. He definitely did not go as slow as he’d intended, as he’d tried to go for Katsuki’s sake; it was impossible to be patient with Katsuki whining into his pillow, hips trembling as he started to push back into Izuku and then stopped himself, like the good boy he so desperately wanted to be.

The moment Izuku got fully inside, with a last little thrust to bring them flush together, Katsuki came. For a moment Izuku didn’t even understand what had happened. One second hands had been curled around Katsuki’s hips, holding tight enough that he would probably leave bruises behind – and god, he liked that thought – with Katsuki finally giving in and pressing back into him to match, and the next, Katsuki had been tightening around him, hands clutching at his pillow, a short, sharp, yell coming out of him before he turned boneless, Izuku’s bruising grip the only thing still keeping his hips up.

“Did you just come again?” Izuku finally asked, tilting a little to see the wet patch on the sheets. “Fuck, Kacchan, that’s so hot.”

Katsuki froze, and Izuku slowly began to rock his hips, testing the waters. He didn’t immediately pull away, didn’t bark out what the fuck, asshole? so Izuku took it as permission – not that he seemed to need much of that, with Katsuki. Katsuki seemed to like it better when Izuku told him what they were gonna do, rather than ask if it was okay. Katsuki was the one with his hands and mouth free at all times, after all.

At least for now.

Achingly slowly, he began to pull out, feeling Katsuki tense up, then try to relax again, failing to get all the way there. He moved maybe halfway, oddly satisfied by the drag of skin against skin, and when Katsuki managed to relax a little, he thrust.

“Fuck!” Katsuki yelled, gripping at his pillow again with knuckles as white as the pillowcase they twisted into.

“You know what to say if it’s too much,” Izuku reminded him, praying to every god he knew that Katsuki didn’t actually use it. He’d respect it if he did, of course – he wasn’t a villain – but he sure as hell didn’t want to stop. “Show me how good of a little slut you are, show me you can take it like a champ and make me come.”

Katsuki didn’t answer, and Izuku watched him carefully as he began to pull out again, eyeing the tight jaw and the fingers that must have ached.

He relaxed again, when Izuku got partway out, and Izuku smirked. It was just like Katsuki to use his actions instead of his words, to tell Izuku he wanted it. But Izuku would work on that, would keep dragging the words out until he was begging so prettily for everything Izuku desperately wanted to give him anyway.

It didn’t take long for Katsuki to get hard again, dick hanging heavy between his legs, and Izuku made a mental note to tease him about it later, about how he was pretty sure it didn’t even take three, even when he’d already come twice. What a greedy little whore he’d found.

“You gonna come for me again?” he asked, yanking Katsuki back as he thrust again, slamming them together in the middle and making even Izuku lose a moan. “Didn’t even wait for permission last time, naughty boy.”

Katsuki groaned, and Izuku thrust into him again, and again, adding a little more distance and force with each stroke. He could feel Katsuki tensing up, struggling to keep it together, but still he valiantly tried to keep his ass relaxed, to let Izuku fuck him unimpeded.

“Gonna fill you up so good, Kacchan,” he said breathlessly. “You like that? Want to feel my hot cum fill your little ass up like you’ve always dreamed of? Like you deserve?”

Katsuki nodded frantically, and Izuku choked out a laugh.

“Tell me, Kacchan.”

Katsuki didn’t speak right away, this time, but Izuku kept going, kept moving. He felt Katsuki twitching beneath him, felt him pushing back into Izuku’s touch to help, felt him squeeze so tight as Izuku pulled out, then relax again to let him push.

“Tell me,” he repeated, curling his fingers to dig his nails into Katsuki’s skin. “Tell me to cum in your little hole.”

He shifted one hand, grabbing Katsuki by the hair again and this time, he pulled Katsuki’s head up off the pillow. His eyes were teary, but his face was so blissful that for once Izuku wasn’t concerned. Pulling his head up made his back bend, lifting his ass a little higher, and Izuku moaned at the sight of it. Seeing Katsuki all bent over and presented so beautifully just did things to him.

“Now, Katsuki.”

Katsuki gasped, eyes falling closed before he finally opened his mouth, and those sweet, sweet words slipped out of his lips.

“Please, Izuku,” he whispered. “Come for me.”

With a last hard thrust, Izuku let go. His cum spilled into Katsuki’s tight little ass, and as he rocked his hips again, riding it out, he saw it spill out around the edges, dislodged by his motion. He reached a hand lower, found Katsuki’s tired little dick, and stroked it a few times, his grip admittedly weak and faltering. Katsuki didn’t seem to care, though, from the way he tightened around Izuku’s dick, a tiny dribble of leftover cum hitting Izuku’s hand, the only thing he had left to give. The rest was soaked into the sheets, and sticking to their skin, making a mess that Izuku dreaded letting the hotel cleaners find in the morning, when they came in to do their job; they were definitely not paid enough for this.

Slowly, Izuku pulled out one last time, relishing the little whimpers and gasps it dragged out of Katsuki in the process. He flopped onto the mattress, exhausted, and Katsuki fell down beside him, his limbs turning to jelly without Izuku there to hold him up.

“Think this room has a bathtub?” Izuku asked, chuckling weakly.

“No,” Katsuki mumbled, voice muffled by his precious pillow. “Showers and onsen.”

Izuku sighed, closing his eyes for a moment, before he quickly opened them again – it was not an ideal time to fall asleep, not with everything to clean up and a Katsuki to check in on.

“Okay,” he said instead, groaning as he pushed himself to sit up. “I’ll find a cloth for now, then we’ll go clean up properly and soak in the onsen for a while.”

“Like this?” Katsuki snorted, making Izuku crack a smile when he saw all the red marks and scratches and early bruises that marred Katsuki’s back. Not to mention the fact that his legs didn‘t seem to work.

“We’ll give it a minute first,” Izuku assured him. “And how many people are gonna be there in the middle of the day? They can mind their own damn business.”

“Fine,” Katsuki caved, with a tired laugh. “But you’re gonna have to be my cane again for a bit.”

“Fine,” Izuku echoed, reaching over to squeeze a handful of Katsuki’s ass – gently, admittedly. “You’re the one who’s gonna need the soak, though.”

“You’re the perv who got jealous of my hand.”

“Granted.” Izuku grinned. “I didn’t see you trying to stop me.”

“Shut up, pervy nerd.”

“Okay, okay, sorry,” Izuku said, laughing all the same. “Just rest for a minute, you’ll be okay.”

Katsuki huffed, but he didn’t bother to argue this time, nor when Izuku gently stroked his back with a warm hand.

“Next time you have to share a room,” Izuku said softly, smirking to himself as he caressed Katsuki’s back muscles, his smooth skin, all the way up to his neck and hair, making him shiver at the gentle touch. “Give me a call first.”
