[NSFW!!!] 8 Simple Rules (for screwing my Childhood Friend) - Chapter 5

Chapter 5: "Honesty. No Exceptions."

Izuku jumped when the door slammed, looking up to find Katsuki storming in, falling face first onto the mattress.

"Rule two," he grumbled, shifting his head into Izuku's lap.

"No questions asked," Izuku agreed, moving his book to one hand, laying the other on Katsuki's head lightly. "I won't say a word."

Katsuki sighed faintly, sinking in to Izuku's touch, and with a little smile Izuku stroked his hair, turning his eyes back to his book.

"Let me know if you want to talk about it," he said softly. "I'll put this down."

"I don't."

"I know. If you change your mind, I meant."

"Mm-hm."

Katsuki turned his head to the side, his eyelashes brushing at rosy cheeks, and soon his face softened, his breathing slowed, his heartbeat returned to normal. Callused hands brushed at Izuku's feet, Katsuki's arms squashed beneath his chest, and Izuku looked down at him once more.

"That can't be comfortable," he murmured, combing his fingers through blond hair. "Are you asleep, Kacchan?"

"Yes."

"Roll over, idiot," Izuku laughed. "Get comfy, I don't mind if you squirm a bit."

"I wasn't worried, nerd," Katsuki grumbled, with no bite behind it. "I'm comfortable right where I am."

"Are you sure? Your boobs might cut off circulation to your arms."

"Fuck you, I'm leaving."

"No, no, I'm sorry!" Izuku grabbed the back of his shirt, holding on when he began to wriggle away. "Stay, Kacchan. I won't call them boobs again."

"Fuckin' better not."

Despite his complaints, Katsuki rolled onto his back, peering up at Izuku as he lay his head back again.

"Better?"

"Yeah," Katsuki admitted. "Just embarrassing."

"How come?"

"I can't hide my face now. Not practically, anyway," he complained, covering himself with his hands to emphasise the point. "I don't want to see that dumb face looking down on me."

"Physically?"

"All of it."

"I don't look down on you, Kacchan. Never have, and never will."

"Mm, so you've said."

"Just relax, okay? I'm here, I'll take care of you."

"I don't need-"

"I don't care," Izuku cut him off. "Whether you need it or not, you've got it. I'm the one who tears you apart when we screw, I'm gonna be the one to take care of you and put you back together as well. No matter what."

Katsuki grumbled something inaudible, looking away, but Izuku caught the little blush that spread through his cheeks.

"My pet," he teased, returning to his little strokes at Katsuki's hair. "You belong to me, the good and the bad."

Katsuki's hand drifted to his neck, and Izuku couldn't help but smile.

"You want it?"

"Shut up."

"You can wear it whenever you want, as long as you've been good. We don't have to be fucking."

"Fine."

He flooded red, refusing to meet Izuku's eyes, but Izuku smiled all the same as he reached into the bedside table. The leather still felt heavy in his hands, and as he fastened it around Katsuki's neck, he felt a little chuckle try to force its way out. Katsuki looked way too satisfied, far too pleased, and for a brief moment Izuku almost accused him of being an imposter.

"I haven't been good," he admitted, closing his eyes again to avoid Izuku's gaze. "Not really."

"Tell me what happened. Take your time."

"I just got mad, that's all."

"And said something you regret?"

"Not really. Nothing special or... or too far, I mean."

"Then what's wrong?"

"What happened to 'no questions asked', asshole?"

"You're allowed to not answer," Izuku assured him, wrapping a loose grip around Katsuki's throat to caress his collar. "But I have a feeling you wantto talk and you're just embarrassed. Does that sound about right?"

Katsuki didn't answer, and Izuku nodded understandingly, scratching lightly at Katsuki's scalp and getting a contented little sigh for it.

"One of those Class B extras," he explained quietly. "They walked by while I was yelling."

"Mm-hm?"

"It's stupid, forget it."

"It's not stupid. What did they do?"

"Said some shit about 'I told you he hasn't changed'."

"Oh Kacchan," Izuku hummed his understanding. "You know that isn't true."

"That's how everyone sees me. The same stupid fifteen year old who was fuckin' handcuffed on stage at the sports festival, who got attacked by a shitty villain before he even started high school, who got in the way during the USJ incident, who was kidnapped by villains because they thought he would join them. That's who I'm always gonna be, to the public."

"Not true, Kacchan. You're amazing, and when people see you out there saving millions of people, beating all of All Might's records, they'll have no choice but to realise you've grown up."

"I'm tired of other people deciding who I am. Why can't I just be me?"

"You can. I'll still think you're amazing, no matter what."

"You're the only one."

"I'm not. Those shitty extras just don't know you like I do, like our classmates do."

Katsuki cracked the tiniest of smiles, a rare sight that made Izuku's heart pound in his chest, blinking stupidly as he stared.

"I'm gonna stay here," Katsuki said finally, rolling onto his side and reaching for a pillow to hold in his arms. "You do what you want."

"Anything I want?"

Katsuki snorted, and Izuku couldn't help but laugh too, tangling his fingers in Katsuki's soft hair.

"I'm gonna take a nap too."

"Yeah?"

"Yeah, c'mere."

He shifted a little, dragging Katsuki up the bed, and despite the grumbled protests it elicited, he wound his arms around Katsuki's waist, snuggling into his back.

"No questions asked," he smiled softly, nuzzling into Katsuki's hair. "Can I add another?"

"Yeah."

"Be honest."

"Huh? I am."

"As a rule," he amended. "Rule five. Be honest."

"I guess so," Katsuki nodded. "You want me to be honest right now?"

"Always. No exceptions."

"I kind of like this," Katsuki admitted. "Letting you take care of me occasionally."

"Any time you want, Kacchan. You took care of me every day when we were kids, it's my turn to repay the favour."

"Okay. Let me nap here, then."

"For as long as you want."

Izuku groaned as he woke up, rays of orange sunlight hitting him right in the eyes, and it took him a minute to piece everything together. Sunset, not sunrise, that was the most important one. Thank god, because he was in no condition to go to class.

"Fuuuck," Katsuki yawned, rubbing at sleepy eyes. "How long did I sleep?"

"Mm... Couple of hours," Izuku mumbled, glancing at his phone, but keeping one arm secure around Katsuki's waist. "Not too long."

"I was meant to do so much shit today."

"Language, Kacchan."

Katsuki snorted, and Izuku smiled, leaning his face on Katsuki's hair again. It was oddly comforting, being so close to him, after so many weeks of fucking and leaving again without a moment to spare.

He was playing a dangerous game, he knew, but he would beat himself up for that later.

"Be more creative," he teased, nipping at the nape of Katsuki's neck. "Swearing is so boring, come up with something fun."

"Yeah, sure," he replied, completely monotonous. "Pound my bum into next week, Deku."

"Perfect. Rule six, no swearing."

"Fuck you."

"No swearing and no lewd noises."

"What are you on about now?" Katsuki sighed, rubbing his eyes again, "Lewd noises?"

"Yeah, no moaning."

"Fine, then no talking either."

"So just a silent room other than the slapping of flesh? Sounds super hot."

"I'll make you scream if you want."

Izuku snorted again, and where he could see a glimpse of Katsuki's face, those lips curled up too.

"You need to go be productive, then?" Izuku asked, a hint of reluctance sneaking into his voice.

"Nah, fuck it, I'll do it tomorrow."

"Oh good, I'm gonna fuck you then."

"Oh, you are, are you?"

"Yeah," Izuku grinned, slinging a leg across Katsuki's thighs and rolling on top of him. "Morning wood, y'know?"

"Sure," Katsuki scoffed, reaching for his belt. "Fine, whatever."

"Nuh-uh, naughty hands. You go up here."

He pushed them firmly up to the pillow, letting Katsuki settle himself comfortably, his fingers twining into the pillowcase without a single word of protest. Izuku paused, contemplating for a moment, then seemed to change his mind again, gently taking the hands back.

"Roll over."

"Huh?"

"You never do any work," Izuku teased. "I want you to ride me."

"H-Huh? Are you serious?"

"Uh-huh!"

"Fuck," Katsuki hissed, flooding red as he sat up, a little flustered. "Yeah, sure."

"But remember, no cumming until Master does."

To Izuku's surprise, Katsuki nodded. No arguments, no protests, no stubbornness, just a little nod as he stripped them both off and reached for the bottle of lube.

"I'll open you up first," Izuku offered, when Katsuki reached for him. "Pry open that tight little hole of yours."

"Fuck that."

"Kacchan," Izuku grabbed his wrist, halting him. "I'm doing it."

"It's fine, it'll work."

"Listen to me, you little whore. Sit back and let me see you gasping on my fingers."

"Ugh, fucking fine."

He snatched the lube from Katsuki's hand, coating his hand in it, and Katsuki watched with a hint of concern as it slid underneath him. He hated this part, hated feeling all that stimulation and not being able to do anything about it, hated how slow and careful Izuku was.

"Three," Katsuki demanded, when he felt the fingertips brush against him. "Make it fast, I want to do this."

"Patience, Kacchan."

"I'm wearing your fuckin' collar and riding your damn cock, you can't give me this one fuckin' thing?"

"Two," Izuku conceded, compromising. "I'll skip straight to two."

"And do it fast. Wreck me."

"Fine, I'll finger you so hard and fast that you can't see straight."

"Yes," Katsuki hissed. "That, do that."

"And you say you aren't a slut," Izuku snorted. "Okay, Kacchan, lean back a little."

He braced himself against Izuku's thick thighs, already breathing hard with the anticipation alone, and Izuku smiled as he slid two fingers inside, suprised by how easily they seemed to fit these days. Katsuki had gotten much better at the whole relaxing thing, letting Izuku do his job instead of fighting him at every step of the way.

Katsuki whined, long and low, watching the almost surgical precision with which Izuku made his motions. It was pure science in that freckled face, a little crease in his forehead as he focussed, concentrating on every little stretch and curl of his fingers. Katsuki reached out, smoothing the crease with his thumb, and for a moment Izuku paused.

"You'll get wrinkles," Katsuki explained. "Stop frowning."

"You're one to talk," Izuku scoffed. "You never stop scowling."

"Yeah but I also have my mother's genetics, my skin is gonna be fantastic until I'm at least fifty."

"Jerk."

"You look fine," Katsuki assured him, in a moment of weakness. "Just don't frown so much."

"Noted. Three?"

"Fuck yes three."

All thoughts of conversation were forgotten in a heartbeat, Katsuki sinking onto Izuku's fingers with no hesitation, biting down on his lower lip a little too hard. There would be a mark there later, but he didn't even care. All he cared about was that twisted and scarred hand filling him up.

"More," he demanded, dropping his hips down in a hurry. "Deeper, harder, more."

"What are you, Kacchan?"

"I'm a fucking slut who loves anal, you got a problem with that, asshole? Fucking do your shitty job so I can get fucked."

Izuku frowned, using his free hand to halt Katsuki in his tracks, the messier hand falling dead still inside of him.

"Is that how you talk to me, Kacchan? Making demands and cursing at me?"

"Come on."

He hooked a finger through Katsuki's collar, dragging him in close, his lips brushing at Katsuki's ear.

"Repeat after me. I'm a naughty little whore."

"Fucking hell, are we really doing this?"

"Yes. Say it, Kacchan. I'm a naughty little whore."

"Ugh. I'm a naughty little whore. Happy?"

"I'm a naughty little whore who needs to be punished."

Katsuki swallowed hard, but nodded faintly.

"I'm a naughty little whore who needs to be punished."

"How do you think I should punish you for your impatience and your language, Kacchan?"

"Make me ride you?"

"Very funny."

Katsuki pouted, looking away to stare at the setting sun as he contemplated.

"I'll suck you off."

"You like doing that, Kacchan."

"I'll do all the work," he clarified, "instead of letting you do it."

"Is that really a punishment?"

Katsuki nodded, hesitating again while Izuku waited patiently.

"I have to wait," he explained. "I have to stop to suck you, and then let you get it back up again before I can be fucked. If you even decide to, after. But you don't miss out, you still get off."

"You actually put some thought into this," Izuku grinned. "I'm impressed, Kacchan."

"You wouldn't let me come up with something half-assed."

Izuku smiled, leaning his forehead against Katsuki's softly. He tangled his fingers in Katsuki's hair, and for a moment they just stayed, pressed together as their breaths became one.

"I have a present for you."

"Huh?"

"Turn around for me."

He released his grip and Katsuki turned away, watching over his shoulder as Izuku rummaged in his drawer again, producing something brand-new, freshly washed.

"You're gonna be full for me while you blow me," he explained, slipping the narrow end into Katsuki's anus. "Hold still."

Katsuki froze in place, blushing furiously as the toy went in further, stretching him wider as it went on.

"Cold," Katsuki whimpered, as it settled in place. "Could have warmed it up first, you know."

"That wouldn't be nearly as fun. Some people soak them in nice cold water first, you know. You should be thankful it was room temperature."

"But the lube was cold," he grumbled. "Your hands are warm when you use those."

"And you like it, don't you? It's different, more stimulating."

Katsuki nodded reluctantly, and Izuku smiled, jiggling the flared base to make sure it was secure.

"There, now you'll stay nice and stretched while you suck me off, and then you'll be nice and ready for me when I want to fuck you."

"Mmkay."

He shuffled back, positioning himself between Izuku's legs, and the parade of different emotions as he moved and felt it inside him was like a show in itself, the opening act for what was about to come.

Katsuki looked up, meeting Izuku's eyes for the first time all night, and sank all the way to the base.

"Jesus fuck, Kacchan, holy shit," Izuku hissed, throwing his head back. "So quick oh my god."

Katsuki just hummed his acknowledgment, swallowing precum, his tongue running over the slit to search for more. It didn't taste good, Katsuki would never pretend otherwise, but the way Izuku responded was more than worth it.

"More, more, more," Izuku demanded, tangling his fingers in Katsuki's hair. "So good, Kacchan, you're so good at this! Don't stop!"

Katsuki hummed faintly, ignoring the dark hair that tickled at his nose, ignoring the way the precum burned the back of his throat, ignoring the shining forests that watched him, just focussing on the way he moved his head and his tongue, the way he moaned loudly around the shaft and felt Izuku tense up beneath him.

"I'm not gonna last long, Kacchan," Izuku laughed breathlessly. "You're too good at this. Didn't have to be so patient after all, huh?"

Around his mouthful, Katsuki smirked, but Izuku was thankfully too distracted to notice. His fingers tightened and his back arched, and Katsuki smugly sank in close again, swallowing as Izuku began to pour down his throat. It came in waves, short enough for Katsuki to swallow them down without making a mess, and when Izuku began to soften, Katsuki rocked back onto his heels. He did his best to remain impassive, but the smug look shone through his eyes, and Izuku laughed when he caught it.

"C'mere," he demanded, dragging Katsuki in for a hug. "Is this okay?"

"Yeah?" Katsuki frowned. "What do you mean?"

"It's okay if I hug you?"

"You think I'm okay with fucking but not hugging?" Katsuki snorted. "It's fine, whatever."

"I just don't know where you draw the line. What are our boundaries?"

"Deku, I have a collar on and a fucking plug in my ass, and you want to have this discussion while I wait for you to get it back up?"

"Just tell me anything that's off limits. Honesty, remember."

"Fine. Kissing." he blushed as he looked away. "Just... Should be someone I'm dating, the first time, you know?"

"You've never been kissed?"

Katsuki shook his head.

"Okay, that's fair," he agreed. "No hand-holding, either, then. Um, no dates, but I don't think we planned on that anyway. No cheesy texts. Anything else?"

"It's fine," Katsuki assured him, rolling his hips gently to test Izuku's readiness. "Don't think too much."

"Ah, fuck, Kacchan please."

"That sounds like a yes to me," Katsuki smirked, leaning in to kiss the base of Izuku's rapidly hardening cock. "Can I ride you now?"

"Are you gonna behave this time?"

"Of course, Master." Katsuki fluttered his eyelashes. "Don't I always?"

"Seductive little minx," Izuku snorted. "Fine, do it."

"You sound so enthusiastic."

"You don't want to get fucked?"

"I do."

"Then stop complaining."

Katsuki pouted, and Izuku cursed himself for buying into it, sighing as he reached out to stroke Katsuki's hair.

"What do you want me to say, Kacchan? You don't seem to be happy no matter how I respond."

"I just want to know that you want it too. Otherwise I feel like I'm doing something creepy."

"I promise, Kacchan, if I didn't want it I wouldn't be here. I am very much looking forward to watching you bounce on my cock until your thighs burn, moaning so loud the whole dorm can hear us."

"Better," Katsuki blushed. "Okay, just let me figure this out."

"Take your time, Kacchan. You look good like this too."

He grumbled a little, but didn't bother to protest it, instead settling for finding the right position to crouch over Izuku's crotch. Reaching beneath himself, he removed his plug with a little gasp, and guided Izuku into his hole, not wincing even a little as he sank down.

"You know," Katsuki murmured, as he shifted his hips a little. "If you fucked me more often, you wouldn't have to stretch me so much."

"Is that right?" Izuku smirked. "So instead of occasional pent-up sex, you think we should make this a regular event?"

"It kind of already is," Katsuki pointed out, bracing his hands on Izuku's abs. "We're here at least once a week, these days."

"How often do you jerk it when I'm not around?"

"What happened to 'no questions asked'?"

"A lot, then, huh? Still humping your mattress instead of calling me?"

"Sometimes," he admitted, nodding as he moved to his knees, dropping a little more firmly onto Izuku's hips. "That's better."

"Sorted?"

"Uh-huh."

"We can meet every night, if you want. Just hang out after dinner. Doesn't bother me."

"Yeah?"

"If we don't feel like fucking we can just do homework or something. Might make our cover easier, too."

"Sure, sounds like a plan."

"All so your little hole can stay open," Izuku smirked. "The lengths you go to, Kacchan."

"Shut up."

He rose up on his knees, letting Izuku's well-lubed dick slide almost all the way out of him, before he dropped down hard. The short burst of pain was exactly what he wanted, a little bit of roughness to make him feel it. Izuku was always too damn gentle with him – well, except when he wasn't, but those times didn't come nearly often enough.

"I like pain," Katsuki confessed, when Izuku shot him an alarmed look over his whines. "Honesty."

"I figured."

"I like this," he moaned, as he impaled himself on Izuku's dick once more. "God, Deku, I like this."

"Then do it. More, Kacchan. Faster. I want to hear you gasping for air."

He nodded faintly, leaning against Izuku's stomach a little more as he moved, an endless chorus of moans falling from his lips as he felt the cock slide in and out, grazing against his prostate, making him feel so damn full. There was no better feeling in the world than having Izuku's perfect cock inside of him, stretching him wide and filling him to bursting.

He squeezed a little as he rose, trying his best to stimulate Izuku a little more with his touch, and smiled faintly when the gasp came from beneath him.

"Good, Kacchan. Now harder. I want to hear your ass hitting my body."

Katsuki threw caution to the wind, blindly obeying the instruction, squeezing tight every time he rose and slamming down hard every time he fell. It was rough, his pace stuttering, his breaths shuddery and with no real pace to them, but every single stroke of that precious cock inside him made him want to cum all over them both. It was all he could do to keep it under control, to focus on the noises and twitches he normally recognised so well, instead of the heat swelling inside of him. He couldn't think straight, his mind was just an unending string of curse words and lewd noises, bitten back with his last ounce of self-control.

"Cum inside me," he choked out, as he leaned back a little to put more weight into his movements. "Please, Master, I want to feel it."

"I won't last if you talk like that, little whore."

"Oh God, yes. More, Deku. More, Master."

"More w-what, Kacchan?" he asked breathlessly, fingertips digging into Katsuki's hips.

"Call me names."

For a moment Izuku fell silent, his grip tightening a little more, and Katsuki wondered if he'd gone too far.

"Faster, slut. If you can still talk, you can still fuck your little hole harder."

"God, yes!"

Katsuki's vision blurred, his thighs burned, all he knew was the fat cock beneath him and the sexy voice giving him directions. When had that damn voice gotten so hot? It wasn't that long ago that Deku had been a squeaky little mess, and now-

"Gotta fuckin' do it myself, huh?"

The grip on his sides shifted, large hands curving around his waist, and then that beautiful dick was rising to meet him. Every fall punctuated by a hard thrust from beneath him, fingers bruising on his skin, lube and precum spilling between them obscenely.

Katsuki couldn't stop moaning, and Izuku managed a smile as he pulled his friend down on a particularly rough thrust, finally conceding his tentative self-control and spilling inside Katsuki's tight ass.

"Do it, bitch. Cum for me. Now."

Katsuki doubled over as he shot his load all over Izuku's stomach, still weakly lifting up and down on the softening cock, his legs shaking as he tried and failed to keep moving.

"Hey, hey, it's okay," Izuku assured him, when tears pooled in Katsuki's glazed eyes. "You did so good, Kacchan. You can stop now, you did so well."

"I couldn't hold it," Katsuki whined, staring down at the sticky mess between them.

"You held it perfectly," Izuku smiled, gently pulling Katsuki down to the mattress. "You waited for permission, just like I asked."

"I meant yours."

Izuku tilted his head to one side, taking a moment to catch on when he saw Katsuki's clenched butt muscles, the fluid dripping from his hole.

"It's okay, Kacchan," Izuku smiled. "You don't have to, we already made a mess anyway."

"But I like it."

"Oh? I'm sorry, I didn't realise. Which bit do you like?"

"Being full," he grumbled, turning his head slightly to hide his blushing cheeks. "And having your... leftovers, inside me."

"Hmmm," Izuku hummed, sitting up and surveying the mess around them. "Okay, we can do that."

"Huh?"

"You've got some, right?" he asked, prodding at Katsuki's clenched hole. "Just not enough to feel full?"

"Uh-huh."

"Then it's a good thing we have our new toy," he grinned, reaching for the discarded plug. "Open up for me, Kacchan."

Reluctantly, Katsuki relaxed, only to tense again in a hurry when he felt the small end poking inside him.

"Stay relaxed, I'll make sure you don't lose it."

With his thighs trembling again, Katsuki relaxed once more, letting Izuku slip the toy inside. It filled him up perfectly, surrounded by the familiar squelch of Izuku's cum as he shifted his hips a little to test it out.

"Better?"

"Yeah," Katsuki agreed, finally opening his eyes again. "Better."

"You never told me you liked to be full after."

"Usually one of us runs off," Katsuki grumbled, wiping his sweaty forehead and only succeeding in adding cum to the mix.

"I thought that was what you wanted. Just fuck and then part ways."

Katsuki shook his head, rolling onto his back to stare at the roof.

"Things get weird after. I can't find the words."

"Shall we go get cleaned up and you can think about it?"

"Yeah."

He shuffled to the edge of the bed, pulling on the dirty clothes Izuku threw at him, and following blindly when Izuku led him to the door.

It was dark and quiet in the halls, and Izuku silently thanked every god he knew for it. Half their classmates were out to celebrate their Saturday night, others were already in bed or otherwise relaxing in their room, and thankfully they made it all the way to the bathroom unimpeded. The shower stalls were small, but they did exist which Izuku also supposed he should be grateful for. Classmates walking in on him affectionately washing cum from Katsuki's hair was frankly the last thing they needed.

He took two stools and dragged them into a cubicle with them, sitting Katsuki down under the hot water and settling in behind him. He leaned into Izuku's chest, and Izuku made no move to stop him, letting him peacefully snuggle in against Izuku's warm frame.

"It's like I feel empty, after," Katsuki mumbled. "Not my ass, but just in general."

"I didn't realise."

"Like I've screwed something up, I guess."

"Thank you for telling me, Kacchan. I won't let you be alone afterward anymore. I promise I'll take care of you."

"I'm fine."

"I know you are," Izuku humored him, tenderly cleaning sweat and lube from both their bodies. "I want to take care of you. Will you let me?"

"If you want, I guess."

He hummed faintly when Izuku washed his hair, and Izuku immediately slowed down, rubbing slow, small circles against his scalp for a little longer. He made a mental note, adding it below "hair pulling" and "head scratches" in his secret database, and soon Katsuki seemed to revive a little in his arms.

"You okay?" Izuku asked, cradling his cheek as he leaned over. "Look at me, just for a minute."

Blood-red eyes darted to his, pupils back to a normal size, eyebrows back to sitting low over his eyelids.

"There's my boy," Izuku teased, nipping at his shoulder lightly. "You had me worried for a bit."

"M'fine," he mumbled, looking away again immediately. "It never lasts long."

"Want me to take this off?"

He tapped on the dark collar, now a little damp, and Katsuki nodded.

"I didn't think I should take it when you were kind of dazed still," he explained. "In case you thought you did something wrong, you know? Instead of being for comfort."

He set it aside with their towels, and Katsuki nodded again, before shoving his head under the stream of water silently.

"Are you sure you're okay?"

"M'tired," he sighed, rubbing water from his eyes as he sat back again. "Need sleep."

"Past your bedtime," Izuku teased. "I'll go to the next stall, you finish getting clean."

"Don't."

"Huh?"

Katsuki grabbed his wrist, dragging him in close, and Izuku couldn't help but smile as water trailed down his body. Katsuki looked good like this, all tight muscles and well-trained limbs, water trickling over his pecs and biceps, dripping off into the puddles at their feet.

"You're a mess too," Katsuki complained, reaching for the soap. "Hold still, dumb nerd."

Izuku giggled, but stood stark in the middle of the cubicle just as he was told, letting Katsuki scrub him down with soap and shampoo. His hands were enticing – Izuku probably would have popped another boner, if he had even an ounce of energy left to spare. They cleaned lube and cum from Izuku's crotch like it was an art form, somehow managing to get him clean without overstimulating him all over again. Katsuki must have practiced those moves a lot.

"Leave it in," he directed, drenching Izuku's hair with conditioner. "You're too impatient when you do it."

"Just tell me when, Kacchan."

"Yeah."

There was something oddly comical about the scene, the pair of them naked and spent, soaked from head to toe, inspecting themselves for any missed semen. Izuku found himself thinking back to when they'd been toddlers in tiny swimsuits, splashing around in the backyard paddling pool at Katsuki's house in the summer. A very different kind of wet and exposed. Thankfully. He was incredibly glad they hadn't discovered anal yet at that age.

"Bend over," he instructed, pushing gently at the small of Katsuki's back. "I'll take this out."

Katsuki blushed, but obeyed all the same, letting Izuku gently slip the plug out of his ass and clean out the remnants of their fun together. He rinsed the toy off, too, setting it aside with the collar before they took turns rinsing their hair out again.

"Kacchan..." Izuku began, resting a hand on Katsuki's waist, surveying the way his hand curved perfectly around it.

"Yeah?"

Katsuki took a step closer, resting their foreheads together for just a moment before he decided it was too intimate, moving instead to let their cheeks hover side by side.

"I was thinking..."

"About?" Katsuki prompted.

"Ah..."

"Honesty, nerd."

"You know what? It doesn't matter," Izuku smiled faintly. "It's too early to talk about next time yet."

"Tomorrow, right? My room after dinner?"

"Yeah!" Izuku nodded, smiling a little brighter. "I'll be looking forward to it!"

"Warn me if you're bringing any dumb new toys."

"Oh Kacchan," Izuku giggled. "That would spoil the fun!"
