Work Text:
The second Izuku managed to peel his eyes open he knew it was going to be a terrible day. Why? He really couldn’t tell you. There was nothing wrong per-say. It’s not uncommon for him to wake up to itchy clothes and the overwhelming sound of electricity thrumming through the lights. It’s not uncommon for him to wake up in a cold sweat with a choked scream on the tip of his tongue. It’s not uncommon for anxiety to build up in his chest steadily and leave him trembling and forgetting how it feels to have air in his lungs.
But today he’s blessedly woken up to none of these things. He slept peacefully for the first time in a long time and woke up comfortably in the light fabric of his favorite basketball shorts and a stolen black shirt, skull printed along the chest, that hangs just slightly off his shoulder in a way that reminds him fondly of how he’s just ever so slightly smaller than the shirts owner. He spares a small smile at the thought as he slips out of bed, choosing for once to procrastinate on changing into his uniform just to see the look of faux irritation on Katsuki's face when he stumbles into the kitchen in the same shirt he just told the blond last night he hasn’t seen since laundry day.
He takes the time to slip on some mis-matched socks, purely just to irritate Katsuki further, before he grabs his phone and makes his way downstairs toward the kitchen. It’s early April, Sakura trees lining the streets and Izuku can’t wait to run his fingers through the pretty pink petals as they walk to class later. He briefly wonders what he should get Katsuki for his birthday this year as he grabs a bowl out of one of the cabinets and sets off in search of the box of AllMighty-O’s he keeps very, very hidden in the cabinet.
“Morning Deku! Is that Bakugous shirt?” Ochako asks as she bounces into the room, already dressed for the day.
Izuku glances at her with a tired smile as he pulls the red, blue and yellow box out of the cabinet. “Morning. And uh y-yeah. It is. I’m mostly just wearing it to annoy him to be so honest.”
Ochako chuckles as she digs through the fridge for something to eat. She was, surprisingly, one of the most supportive when Izuku and Katsuki had revealed their relationship to the class nearly a year ago. Surprising because while Izuku can be a bit oblivious at times, he’s not dense. He knew Ochako had a massive crush on him first year. Hell, he can admit he even had a brief crush on her as well before he realized his feelings were less romantic and more just a projection of the neglected positive interactions from his childhood.
Thanks therapy.
He had thought at first that he’d have to let her down gently, fearing that his relationship with Kachaan would damage their friendship. But then Ochako admitted that she had gotten over her little puppy-love crush not long after summer break started where she then realized she instead had a massive crush on Tsu. He made a small joke about her having a thing for people with green hair but expressed his full support and now they gush to each other about their respective romantic interests at every opportunity.
“No wonder he calls you a brat all the time.” She jokes and Izuku can’t help his small little smile.
“Yeah well, he chose this. He’s known me our whole lives, if he didn’t know what he was getting himself into he shouldn’t have marched his perky little as-”
“Oh Midoriya! Uraraka! Good morning.”
“Morning Iida!”
Izuku clears his voice of the squeak and ignores Ochako's little giggles as he finally opens his cereal box and starts tipping it forward into his bowl. Only just as the sweet cereal starts to shift forward the box is snatched from his hands and the squeak he abolished seconds ago returns with a deep blush to accompany it. He turns to meet a fierce red eyed glare and withers slightly under his boyfriend's scrutiny.
“How many times I gotta tell you to quit eatin this shit?” Ah right. That’s why Izuku keeps it hidden.
He makes a move to snatch the box back but Katsuki just holds it high above his head. Izuku is far too dignified to hop like some desperate bunny for a box of cereal. So instead he simply folds his arms and pouts with a small glare. Katsuki, as per usual, is completely unaffected as he closes up the box. Izuku offers a tiny smile, however, when instead of throwing it away like he normally would, Katsuki just simply replaces it in the cabinet and turns back to Izuku.
“I’m making omelets. You’re gonna learn. Again. Because I refuse to date someone who can’t even make something as simple as a damn omelet.”
Rude.
“Kachaan’s gonna teach me?”
“Who the fuck else, dipshit?”
Izuku snickers softly before making a soft noise as a boney finger jabs into his chest. “Is that my fucking shirt?”
“I’m gonna go get ready for class, be back in time for omelets. Love you!” And Izuku races away to the sounds of small explosions popping in the kitchen.
–
Fingers loosely lace with his own as they make the short trek to the school. Despite Izuku's tendency to mumble, these walks are always made in blissful silence. Katsuki is generally a morning person but yet mornings are one of the few times in the day that he’s quiet. Izuku, on the other hand, is not a morning person at all. Yes, he wakes up early most days. He can often be seen racing through his breakfast before going on a morning run before classes start. And on the days he forgoes his run and takes his time in the mornings he’s more subdued. It takes a while for his generally overactive mind to wake up.
And so they just walk in a comfortable silence, a scarred hand reaching up to run through the cherry blossoms as petals fall slowly around them. Izuku offers a tiny smile as Katsuki takes a second to pluck a few petals from his wild curls. Izuku can’t help but have a newfound appreciation for Sakura's now that he and Katsuki are dating. Sakura flowers have many meanings but Izuku’s favorite was always that of new beginnings and rebirth. They had worked so hard to rekindle their friendship alone. They've been through hell together since entering UA. And now here they are, hand in hand and walking the familiar path to a future they plan to go into together.
Izuku loves his Kachaan. That will never change.
“So, what’s on the agenda for today, nerd?” Katsuki asks, finally breaking the silence between them as they walk through the school gates.
“Oh um, well after classes I have training with AllMight again and then a shower. And then dinner. I think tonight is Kminari’s night which means I’ll probably stay close just in case a fire starts.” Katsuki snorts as they make their way to class 2A and Izuku smiles.
“And then I thought maybe we could hang out in your dorm, study a bit.” Which of course will inevitably turn into a passionate makeout session because they’re teenagers and obsessed with each other and have nothing better to do. “If you want?”
Katsuki huffs and drops his bag at his desk, turning to lean against it as he rests his hands on Izuku's hips. As if second nature, Izuku takes a step closer, further into his boyfriend's space, and runs a hand through the soft blond spikes. Katsuki looks up at him with a familiar soft expression and his fingers flex slightly where they rest on Izuku's hips.
“Sounds good, nerd. While you’re training I’ll go get snacks. We can watch a movie after we study.”
“Wow! A movie and snacks huh? What’s the special occasion?” Izuku teases.
Katsuki tsks. “Don’t be an ungrateful brat. I can’t just want to watch a movie with my dumbass boyfriend?”
Izuku giggles and steps closer again, moving his hands to rest against Katsuki's cheeks as he leans closer. “Course you can, Kachaan. I look forward to it.”
He closes the gap between them, pressing their lips together softly. Katsuki returns the kiss easily, hands sliding up Izuku’s side and pulling a small shudder from the younger teen. The people already in the room leave them be, thankfully being the more early risers who are respectful enough to not tease or interrupt the pair's little moments. Izuku is grateful. Of course, he loves all of their friends equally. But in moments like this, where Izuku’s whole world is confined to crimson irises and ash blond hair, he can do without the wolf whistles and teasing jeers.
“Can we watch the first AllMight movie again?” Izuku whispers against his boyfriend's lips.
Katsuki groans and thunks his head against Izuku's shoulder, though he only pulls Izuku closer. “Fine. Whatever you want, Zuku.”
Maybe today won’t be so bad after all.
–
Izuku pants heavily from where he sits on the ground. He’s coated in a thick, uncomfortable layer of sweat. He abandoned his shirt ages ago and he’d consider stripping his shorts as well if it weren’t for the mortification that would come with doing that in front of his mentor. He’s tired and his body aches. He just wants to go take a nice long shower and cuddle up with his Kachaan while they watch that trashy AllMight movie and binge Takis all night.
“Doin alright, my boy?” Yagi asks as he comes over with a fresh bottle of water.
Izuku takes the bottle gratefully and chugs half of it immediately. He then tilts his head back and pours the remaining cool water over his face. His curls will hate him for it later but they’re already drenched in sweat anyway so Izuku can’t really bring himself to care about any of that right now. He heaves one last deep breath and offers Yagi a shaky thumbs up.
“S-sorry AllMight. Just needed to catch my breath. We can keep going.” He says, starting to stand on shaky legs.
It’s not that his training is hard per-say. It’s certainly not easy, nothing with One for All ever is, but since his mentor's retirement last year he’s been less physically involved in Izuku's training. And, blessedly, he isn’t the only one involved anymore either. Since Izuku's vigilante escapades last year, and therefore everyone finding out the truth of his quirk, he’s gotten much more help. Usually Yamada-sensei helps. Every so often Aizawa and Shinsou join as well. Katsuki has been a constant help since he found out months before everyone else.
But today Yamada-sensei had to patrol early. Aizawa had something to attend to with Eri, which will always be a priority in Izuku's opinion, and therefore no Shinsou. And well, Izuku already knows that Katsuki is patiently waiting for him at the dorms. And Izuku is ok with that, really he is. He loves his mentor deeply and cherishes every moment they have together. But Izuku has always had a terrible habit of pushing himself too far. Katsuki and Aizawa do their best to keep him from overworking himself, reminding him that while it’s good to be so determined to be great, he can’t achieve greatness if he puts himself in an early grave.
AllMight tends to forget those reminders.
“If you’re sure, my boy.” He says softly, stepping away as Izuku offers a small tired smile.
Izuku takes another deep breath, gets into position, and calls One for All. He’s working on blackwhip today. By now his quirk control is nearly perfect. But since the war ended blackwhip in particular has been being difficult. Izuku knows that it’s just because his emotional state hasn’t exactly been at its peaks. The survivor's guilt alone eats away at him in the lower moments. He still sees Katsuki's dead eyes staring at him when he closes his eyes. Still feels the phantom emptiness of decayed arms.
He still thinks about Tenko and how badly Izuku failed him.
“You did what you had to do, Izuku. There was no saving him.”
Warm hands cupping his cheeks. Gentle thumbs wiping his tears in the middle of the night. Gentle red eyes staring back at him in concern.
“But I-I wanted to save him. He deserved to be saved, Kachaan.”
Dead eyes. Blood. So much blood. Marring his soft blond locks. Izuku squeezes his eyes shut. He can only imagine how that statement must have felt like a slap in the face to his boyfriend.
“He did. He deserved to be saved. And Zuku, you gotta know that you saved him in the only way you could. He’s resting now. You did what you had to do.”
Izuku yelps as Blackwhip wraps around his own head, slithering over his mouth and eyes. More tendrils wrap around his arms and legs and he trips, falling forward onto the matt below him. He hisses, the sound muffled by his quirk, as his head slams into the matt. A frustrated growl rips out of him. Calm down. He just needs to calm down. He shuts his eyes and takes a few deep breaths, mentally slipping into his happy place. His happy place just so happens to be thoughts about Katsuki but that’s neither here nor there. Blackwhip briefly wiggles against him, reflecting the contentment that thoughts of his boyfriend brings him, before it slowly slithers away as his heartbeat calms and Izuku sits up.
“My boy-”
“I can’t. I’m sorry A-AllMight I just- I think I’m done for the day.”
Yagi looks at him, eyes calculating but expression soft. Izuku takes a few deep breaths, head ducked as he waits for the disappointment from his mentor. Instead, a frail hand drops into his damp curls and Yagi nods.
“Alright. Go on then, Young Midoriya. Wonderful work today. Go relax.”
Izuku offers a small smile and soft thanks. He takes the time to hurry through some cool down stretches before grabbing his things and draping his soaked shirt along his shoulders before making the trek back to the dorms. Blessedly, nobody bothers him as he makes his way to his dorm for a change of clothes before heading to the showers. He stands under the warm stream of water a little longer than he usually would, eyes closed and enjoying the feeling of warmth washing over his aching muscles.
Once done he quickly dries off and gets dressed, gathering up his dirty clothes and bringing them with him to Katsuki's dorm. He’ll just dump them in the blonds laundry and hope he doesn’t get too much of a lecture for mixing their laundry. He had every intention of spending time in the common room tonight, waiting until after dinner to spend time with his boyfriend alone. But after everything that happened during training Izuku doesn’t think he could handle the chaos of a common room full of hero hopefuls that don’t understand volume control or personal space.
Again, Izuku loves his friends. Really.
He knocks twice on Katsuki's dorm room door before just twisting the knob and entering. He glances at his boyfriend, the blond sprawled out on his bed watching him over the head of a manga as he shuffles into the room and drops his dirty clothes in the hamper by the closet. Neither of them say a word as Izuku crawls into the bed, settling on top of Katsuki and wrapping his arms around the blonds waist. He rests his head on Katsuki's chest, head turned and finding a bit of relief he didn’t know he needed at the steady sound of a beating heart.
A page turns above him before Katsuki shifts slightly. The manga is set on the night table before a strong hand runs through his still damp curls and Izuku melts against him. Here, safe in Katsuki's arms, Izuku doesn’t have to worry about the horrors of the world. He doesn’t have to think about death and destruction and regret. Doesn’t have to see the blood on his mangled hands or hear the screams of terrified civilians. He’s in his safe space. He’s where he belongs.
And finally, he can breathe.
“You wanna talk about it?” Katsuki asks softly.
Izuku shakes his head slightly. Despite the denial though, his mouth opens to speak before he can decide against it.
“Just…I dunno. Training was hard. Blackwhip is being dickish lately and I guess I got a little lost in my head again. Just wanted to see you. M’sorry.”
A gentle bop to his head coaxes him to look up at the soft expression above him. “Shut the fuck up, idiot. If you need me, I’m here.”
Izuku can’t help how his lip wobbles. “I just… we won. Right? Y-you killed All for One and…and then I killed Shigaraki. Yeah?”
Katsuki just offers a nod, knowing not to interrupt. “Then why does it all still hurt?”
Katsuki's face softens more as Izuku's crumples. He presses his face into the blonds stomach as the tears start. Gentle fingers card through his curls, working out knots and scratching soothingly every so often and Izuku wraps his arms tighter around the slim waist below him.
“It hurts because you care, Zuku. Because despite everything, you’re not a killer.”
“But-”
“No, listen to me.” The hand in his hair moves to gently nudge his cheek.
Izuku sniffles and picks his head up again. Katsuki cups his cheek, gently wiping the tears away, and Izuku finds himself leaning into the warm palm as it eases something inside of him and again, he can’t help but melt.
“You. Are not. A monster.” Katsuki says firmly. “I know you wanted to save Tenko. I know you wanted to keep the city intact. I know you wanted to do it all alone like the self-sacrificial idiot you are. I know-”
Izuku watches as his boyfriend takes a shuddering breath. Despite his own tears he gently rubs thumbs along the skin of Katsuki's waist below his shirt. The blond shudders but relaxes below him. The thumb on his cheek strokes soothingly, wiping tears as they come and keeping Izuku grounded. And god, in this moment Izuku can’t help but fall deeper in love.
“I know you blame yourself for my death.” Izuku flinches.
“Kacha-”
The hand on his cheek slides down to cover his mouth. “You talk too much. Shut up.”
Izuku huffs but nods. “I know you blame yourself for a lot of shit that’s just not your damn fault. And Zuku, ya gotta let it go. You gotta find a way to accept it all and live with it. If you don’t, you’ll never move on.”
Izuku stares for a minute before slowly pulling away from the hand on his mouth. He shifts to sit up, loosely straddling his boyfriend as he wipes his face. Katsuki rests his hands on Izuku's waist, rubbing his hips soothingly as he looks up at him. His expression is still soft, patient but firm. Izuku just wants to kiss him. Wants his Kachaan to hold him and fight away all his stressors and pain. But even Izuku, the dreamer he’s always been, knows that it’s not realistic.
“Have you? M-moved on that is?”
“Mm. Nah. Not really. But I’m tryin to. Gets a little easier every day.”
“What helps you?”
“Well for starters, I started seeing a therapist. My parents made me. It helps. M’less angry and shit now. Talking helps. But mostly, it’s…well it’s you.”
Izuku furrows his brows slightly. “M-me? How do I help?”
Katsuki, always with the audacity, rolls his eyes.
“It’s not something that you do, Deku. You just help. Having you around, knowing you’re here and alive and as annoying as ever, it makes the thoughts a little quieter. Being able to cuddle with you when you spend the night or talk to you whenever, it helps with the nightmares. Sometimes I think you might make the heart problems worse but if your dumbass gives me a heart attack some day it’ll be worth it.”
“Kachaan, that's not funny.”
“I think it’s hilarious.”
Izuku shuts him up with a soft kiss, leaning down and slotting their lips together in what's become a very familiar practice between them. The hands at his waist stop moving, gripping ever so slightly and Izuku sighs softly against the blonds lips. They both relax into the kiss, melting together into the bed. Izuku has never felt fuller, more at peace, than he does here. With his Kachaan, Izuku knows that he’s safe. That he’s loved. He can be himself. He can scream and cry and melt and smile and face no judgement for any of it. And in this moment he realizes-
“You help too.”
Katsuki hums softly against his lips, staring up at him with a warm, loving expression. Izuku is always quick to express his love for Katsuki, saying those three simple words at every opportunity. It’s the first thing he says when they see each other and the last when they separate. He texts it at random through the day or in the middle of the night so that Katsuki wakes up to it in the morning. Telling Katsuki he loves him, while not necessary, is his favorite thing to do.
It’s almost never said back. Katsuki doesn’t feel the need. And Izuku can’t help but agree. His Kachaan shows his love in other ways. Gentle touches and soft kisses. Making Izuku’s favorite foods when he’s upset or cuddling him when he’s having a bad day. Being vulnerable in moments like these knowing Izuku needs to know that he’s not the only one breaking apart at the seems.
And right now, looking into those deep, loving scarlet eyes, Izuku has no room for doubt.
“What are you starin at?” Katsuki asks.
“You.” Izuku whispers.
A pretty pink tints Katsuki's cheeks and he rolls his eyes. A hand moves to the nape of Izuku’s neck and pulls him closer, capturing his cheeks once more in a deeper kiss than before. Izuku returns it eagerly, soaking up every ounce of love and affection he can get from the beautiful boy below him. By now his tears have dried. The stress from earlier has drained out of him and while yes, the pain is still there, Izuku realizes that it’s just a bit more bearable now.
They kiss like that for a few minutes, soft and warm and so comforting. His head feels fuzzy as contentment and affection swirl in his chest. And then Katsuki deepens the kiss, gently forcing his tongue past Izuku's plump lips and he somehow melts further. Their tongues slot together in a somewhat sloppy dance. And when Izuku feels the need for air he pulls away with a gentle bite to Katsuki's lower lip and takes a deep breath.
It catches in his throat when a small whine reaches his ears. Izuku stares down at Katsuki, cheeks flushed and eyes wide. Katsuki averts his gaze in embarrassment, though he doesn’t try to shove Izuku away. His cheeks are dusted with a deep flush and his chest heaves ever so slightly as he takes deep breaths. And something in Izuku snaps.
Before he can think any better of it, Izuku rolls his hips down against his boyfriend, earning himself a soft groan from the blond as hands find his hips again and hold him there. This isn’t the first time they’ve done something like this. They are teenagers, still suffering through puberty and so they’ve had their fair share of awkward boners or makeouts that get too heated. Izuku knows what it feels like to rub his clothed erection against Katsukis until completion. He knows the weight of his boyfriend's cock in his hand and revels in the sound his Kachaan makes as he pumps a scarred hand down the length.
But he’s never heard Katsuki make that noise before.
He leans back in, slipping his tongue back into Katsuki's mouth as his hips roll once more. Already he can feel the small tent growing in Katsuki's pants and he knows his boyfriend must be feeling his own. A jolt of pleasure leaves him groaning into his boyfriend's mouth and the hands on his waist grip tightly. Izuku shifts slightly, settling more of his weight on his knees and grinding down harshly, drawing moans from both of them.
“Fuck, Zuku. Don’t start something you can’t finish.” Katsuki warns.
Izuku pants softly against his lips, hesitating. He’s right. Izuku is probably not in the best mental state for something like this. But yet, god he wants it. He needs it even. And as he grinds down again he thinks maybe he even wants more. He’ll take whatever Katsuki will give him, even if that means he gets nothing. But in this moment he can’t help but crave more. He can’t help but wonder how it would feel to have Katsuki inside of him.
Of course, it’s not the first time he’s had this thought. Izuku is only human after all. And it’s hard to keep his thoughts clean when he’s dating Bakugou fucking Katsuki of all people. Izuku can reluctantly admit that he’s woken up many times with a moan on his lips, dipping a desperate hand into his boxers in the middle of the night with a familiar, childhood nickname slipping out as he works himself to completion.
“Deku.” Katsuki groans softly and Izuku twitches.
He hadn’t even realized that his pace has sped up, grinding almost desperately against his boyfriend with small moans and whimpers slipping past his kiss bruised lips. They’re both painfully hard at this point, dangerously close to climax and Izuku whines as he presses his face into Katsuki's neck. A hand slips up under his shirt, pressing flat to the small of his back and the touch tingles against Izuku's skin.
“Please? P-please Kat. I want you. I want you so badly.” The beg slips out before Izuku can stop it.
A groan sounds in his ear that has Izuku grinding his hips again with a moan. Katsuki’s own hips thrust up against him and Izuku can only let out a startled yelp as the blond uses the momental to flip their positions, leaving Izuku sprawled out on his back with his boyfriend hovering over him. A strong arm braces under the pillow beside his head as Katsuki's weaker hand rests on his waist. He stares down at Izuku with an intensity that leaves his mouth dry and his dick jumps in his pants.
“Say it again. Tell me you want this Deku or I swear to god-”
“I want this. I need it. Please?”
“Deku-”
“Katsuki.”
Katsuki immediately snaps his mouth shut, staring down at him. His chest heaves as he catches his breath and Izuku watches his Adams apple bob as he swallows. Without thinking he reaches a hand up and presses two fingers to it, tracing lightly before dragging his fingers to Katsuki's pulse point and pressing down slightly. He takes a deep breath as he feels the beating below his fingertips.
“I want you to fuck me.”
Katsuki mumbles a small curse, his hips twitching forward and pressing briefly against Izuku's own.
“Ok. Yeah ok. Fuck. We…we’ve never done this before.”
“I-I know. I know but I…I trust you. You can say no. I just-”
“Fuck you if you think I’m gonna say no. You just dry humped the life outta me you asshole. I’m gonna fuckin wreck you.”
Izuku chuckles softly and reaches up to cup his cheek with the hand that was previously pressed into Katsuki's neck. His other hand slowly runs down his boyfriends side until his fingers brush the waistline of his sweats. He gently tugs at the drawstrings of the sweats until they come undone. And just like that, any resolve Katsuki had left snaps. He’s quick to pull Izuku's shirt up and off of him, tossing it to the side before he dips down and begins pressing kisses into Izuku's neck. He tilts his head back into the pillows, granting access as his hand slips into Katsuki's boxers and wraps around his length.
Katsuki moans into his neck, hips bucking into Izuku's hand and he gives a gentle squeeze, rubbing his thumb along Katsuki's slick tip. Katsuki slips a hand down to tug his sweats and boxers down enough to free his cock before doing the same with Izuku's shorts and boxers. He presses flush against Izuku's waist, resting his hand over Izuku's and gripping their dicks together with a groan. Izuku whimpers at the first pump of their cocks against each other, panting softly as slick lips suck a small bruise into his neck.
“Kachaan. Oh god. Feels good.”
“Yeah? One stroke and you’re already gone? That’s fuckin pathetic.”
And oh. Oh that’s a new feeling. Izuku's dick jumps at Katsuki's words and he feels the blonds breath hitch against his neck.
“You like that? Fuck. Shit, I’m not even surprised. You always were a little freak.”
His hand starts moving again, bringing Izuku’s with it and pulling a moan from him as they stroke together at a steady pace.
“Ah- K-Kachaan. Please?”
“Shut the fuck up, I’m getting there.”
Izuku whimpers as Katsuki pulls his hand away. Izuku continues pumping them steadily, revelling in Katsuki's noises above him as he reaches toward the night table. Izuku doesn’t need to look to know what his boyfriend is searching for. He’s seen the half used bottle of lube in Katsuki's drawer. He’s wondered if Katsukis ever thought of him while touching himself, though he’s never had the courage to ask.
“Shit. I don’t have condoms. I didn’t think-”
“S’ok. We’re both virgins. I trust you.”
“You sure?”
“Yeah. Why? You nervous?”
Izuku glances at Katsuki, noticing the hesitant look in his eyes and the furrow of his brows. His lips are pressed in a firm line. Izuku’s hand stops moving and Katsuki snaps his head to look at him. He’s sweating a little bit, lips red from their makeout and hair disheveled. He already looks fucked out despite the lack of sex. Neither of them have even cum yet and yet Izuku is more than willing to end it all now If it’ll put his boyfriend at ease.
“Kachaan? Hey, we don't have to do this.”
Katsuki shakes his head and pulls the lube out of his drawer, setting it beside them on the bed. “No it’s ok. I want to. I just…I don’t wanna hurt you.”
“Oh, Kat. You won’t. And if you do, I’ll stop you. I promise. We’ll go slow, yeah?”
Katsuki takes a breath and nods and Izuku finds himself wondering how he’s somehow the confident one between them right now. Maybe it’s the mental exhaustion of the day. Maybe it’s the sexual tension that’s been between them since that first dream months ago. Maybe it’s the fact that Izuku genuinely can’t think of anything he’s ever wanted more than this right now. But somehow Izuku can’t identify a single nervous feeling.
“Right. Ok. Clothes. Off. Fuck this handjob bullshit. I wanna see you naked in the next five seconds.”
Izuku releases a small breath and he’s quick to shimmy out of his shorts and boxers as Katsuki does the same. The blond practically rips his shirt off and tosses it aside. Katsuki settles between Izuku's legs, resting a warm hand on his inner thigh. Izuku forces his body to relax. He knows what comes next. He doesn’t want to end up hurt.
“Have you ever done this before?” Katsuki asks as he slicks up some fingers.
Izuku blushes harshly and turns his head away in embarrassment with a small nod. “U-um yeah. A few times.”
“Yeah? And?”
“And?”
“You like it?”
Somehow Izuku blushes more.
“Uh…y-yeah.”
“Good.”
With that, Katsuki slips a finger slowly past Izuku's rim. He inhales sharply, tensing right back up immediately. Katsuki stills, watching him intently as he waits for Izuku to relax. It feels much different from Izuku’s own fingers. Izuku, whose fingers are shorter but calloused and thick. He struggles when fingering himself to find the right angles or reach the right spots, often having to resort to his odd flexibility in order to please himself. It can be uncomfortable and often he feels it’s not worth the effort.
But with Katsuki, just one thin finger already has him on the verge of unraveling. He reaches deeper with just one finger than Izuku ever can without bending his back in odd positions. And god, Izuku can only imagine how it’ll feel once those fingers are replaced with something else. Something bigger. Something Izuku can already feel himself beginning to drool over.
Hesitantly, Katsuki begins moving. He wiggles his finger slightly, bending it in just the right way to have Izuku gasping softly, before he pulls back and begins thrusting into him. Izuku pants softly, fingers flexing in the sheets, and he doesn’t even notice when he starts rolling his hips back into each small thrust until a second finger joins and Katsuki begins scissoring him open.
“Oh fuuuck.” He moans out softly, pressing his head back slightly as he clenches around the intrusion.
“God you look so good like this, Zuku. So perfect. I can’t wait to fuck you.”
Izuku moans and glances down at him, immediately making eye contact. Katsuki watches him with interest, cataloging every twitch, every noise, every facial expression. He sinks his fingers in deep, curling up and his fingers brush against that little bundle Izuku was waiting for. The reaction is immediate. His back lifts up off the bed as he grips the sheets in both hands and moans.
“The fuck?”
“That- there. That- that thing you t-touched. Prostate. It was my prostate. Please Kat, do that again.”
Katsuki curses and presses his fingers into that spot again, massaging slow circles against it and Izuku lets out a little keening sound as he squirms. He pistons his hips down into Katsuki's fingers, seeking more pleasure. Katsuki groans and grips Izuku's thigh where his hand still rests. Izuku whimpers at the feeling and reaches down. Katsuki takes his hand with his freehand, squeezing gently and providing a sense of grounding through the pleasure rolling through him.
“Kachaan please? Please, I need you.” He begs softly.
“Ok. Ok. Breathe nerd. I got chu.”
Izuku wonders if Katsuki will always be this soft during sex or if this is a one time thing. Though, if he’s being honest, he couldn’t care less. He wants any parts of Katsuki that his boyfriend is willing to give him. If that means a lifetime of soft love making then Izuku is more than happy with that. And as Katsuki pulls his fingers away and moves to lean over him Izuku reaches up to cup the blonds cheeks and smiles like the dopey little lovesick loser he is.
“I love you. I love you so much, Katsuki.” He whispers softly.
“Fuck. I love you too, Izuku.”
Katsuki leans down, slotting their lips together in a kiss far softer than Izuku would have expected given the circumstances. Still, he melts into it, relaxing on the bed below the man he loves. And Izuku hopes this never ends. He wants his Kachaan for the rest of his life, he wants these soft kisses and tender touches. The unconditional love masked by half-assed insults and foul language. He wants to marry this boy some day and spend the rest of his life with his Kachaan.
Of course, as that last thought filters in, so does the tip of Katsuki's slick cock. Izuku breaks the kiss with a whimper and presses his hips down, unintentionally forcing Katsuki just that tiniest bit deeper. The stretch burns just slightly and maybe Izuku is a masochist but god does it feel devine. Slowly Katsuki bottoms out, stilling with a groan as they both adjust. Izuku wraps an arm around his boyfriend's shoulders, digging his fingers in slightly as he breathes. Katsuki presses his face into Izuku's neck, panting softly as warm hands run up and down Izuku’s sides soothingly.
“You’re so tight, baby.” Katsuki whispers softly into his pulse.
Izuku swallows thickly and subconsciously clenches slightly, pulling a hiss from his boyfriend. He runs a hand through the blond locks in apology and slowly relaxes. Izuku knew Katsuki was big but he never thought it would be like this. Even now, just pressed inside and unmoving, Izuku can feel every twitch and pulse press against his prostate and he wonders if either of them will last any longer than just a few minutes. Even if they don’t, Izuku can’t bring himself to care.
“When you’re ready, Kachaan.” He whispers softly and feels a nod against his neck.
It takes another minute but then Katsuki's hips roll forward and they groan in unison. Izuku keeps himself wrapped around his boyfriend, one arm around his shoulders while his free hand stays buried in blond spikes. His knees bend subconsciously, caging Katsuki in and resting his knees against his sides. He leans his head back, lips parted and eyes closed as Katsuki's hips continue to roll into him slowly.
And then Katsuki pulls out to the tip and pushes back in and that alone is enough to have Izuku's brain fuzzing over. He loses his grip on his filter, a moan slipping out with the next slow thrust and his fingers flex into Katsuki's shoulder. It’s slow but oh so good already and Izuku doesn’t feel an ounce of regret.
He came to Katsuki's room so that he wouldn’t have to think about the things that plague his mind every day. He had initially just wanted to cuddle and be reminded that he was safe. That he had someone who understood the pain of it all. He just wanted his Kachaan. And, well, he got everything he wanted and more. And here, wrapped up in each other in the most intimate way, how could Izuku regret a single second of any of it.
“Kachaan. So good. Please? I love you. I love you. I-I need- ah-”
Katsuki groans and shifts back just enough to press their foreheads together. He reaches down, pressing both hands against the backs of Izuku's thighs and pushing his legs up just enough to shift a little deeper into him. Izuku's eyes roll back on the next thrust with a soft cry as Katsuki snaps his hips directly into Izuku's prostate. Above him Katsuki pants softly, his hip snapping into Izuku at a faster pace. He angles for that little bundle of nerves with every thrust, sending waves of the most intense pleasure Izuku has ever experienced rolling through him.
“A-ah- Kac-haan. Oh god. So good. So good, Kat. please? Please don’t stop?”
The words barely register but yet Katsuki seems to drink it all up with ease. He smirks slightly down at him, lifting his head briefly to kiss Izuku's sweaty forehead before pressing their foreheads together once more. Izuku melts at the gesture and returns the affection by prying his iron grip from Katsuki’s hair and running his fingers through the golden locks soothingly.
“Zuku. Izuku, fuck. M’close. Gonna fuckin- ah- gonna-”
“M-me too. Kachaan please? Please? I- mm- I wanna cum. Please let me cum?”
Katsuki reaches between them and wraps a hand around Izuku's cock, immediately stroking him in time with his thrusts. Izuku arches up against him, chests flush against each other as he cries out with Katsuki's name. Slow, warm tears slip down his cheeks and Izuku knows he must look like a mess, eyes rolled back and crying for his boyfriend's cock. Moans and whimpers and begs spilling from his drool slick lips filthily like a painted whore. Hips rocking desperately into each thrust as his climax rapidly builds.
“Say it. Say it again.” Katsuki whispers, pressing their lips together but panting too heavily for it to truly be a kiss.
“Wha- oh. I- ngh- I love you.”
Katsuki squeezes just below the head of Izuku's cock and whether it was silent permission or not Izuku isn’t sure but it doesn’t matter. Electricity shocks through him and his throat suddenly feels raw as Katsuki's name rips from his throat. He cums. Hard. Thick, warm ropes staining his stomach where it shoots past Katsuki's hand. His whole body tenses and trembles in the aftershock and he clenches down on Katsuki tightly. The feeling of cum flooding his ass is odd but not unwelcome. It’s warm and slick and he can feel Katsuki pulsing inside of him, feel every spurt of cum that coats his inner walls and slicks out of him with every small, slow thrust as they ride out their orgasms together.
Eventually Katsuki stills deep inside of him, softening uncomfortably but yet neither of them moves. They breathe each other's air and rest against each other as the aftershocks slowly fade. Izuku gently unravels his limbs from his boyfriend, dropping the hand in Katsuki's hair as his legs fall open. The hand on his boyfriend's shoulder moves to rub slow, soothing circles into his shoulderblade before settling for running up and down his spine.
In return, Katsuki wipes his dirtied hand on his thigh and moves both palms to Izuku's hips. Izuku groans at the warmth of his boyfriend's quirked palms as they gently massage his waist and run up his sides, working out all the aches that are starting to settle into him now. Katsuki slowly pulls out, both boys groaning at the feeling, and Izuku makes a face at the uncomfortable feeling of cum leaking out of him.
“I know, baby. Just relax.” Katsuki whispers.
Izuku nods, still breathing deeply. He whines softly as Katsuki peels away from him, soothing easily with a short, soft kiss. Katsuki grabs a soft towel from his dresser, quickly cleaning himself before gently wiping the cum from Izuku’s stomach and ass. He slips on a fresh pair of sweatpants before helping Izuku into a clean pair of boxers and one of his hoodies Izuku already plans to steal.
He turns onto his side, biting back a groan at the aches, and nuzzles his nose into the fabric of the hoodie. He breathes in deeply, relaxing at the burnt caramel and vanilla scent of his boyfriend. Katsuki huffs softly nearby before sitting beside him and burying a hand in his sweat- damp curls. Izuku pries his eyes open and looks up at him.
“Drink some water. We can relax for now but we’re both taking a shower later after dinner.”
He helps Izuku sit up slightly and hands him a water bottle. “Together?”
Katsuki snorts. “You’re gonna be the death of me. Yeah, sure. Together.”
Izuku smiles and sips at the water. He reaches over Katsuki to put the bottle on the table before making grabby hands until Katsuki chuckles and lays down, pulling him close. Izuku wraps his arms around Katsuki’s waist and nuzzles his face into his boyfriend's side. Katsuki plays gently with his hair, working out tangles and attempting to tame stray curls.
“Do you…do you regret it?” Izuku asks softly.
“Does it seem like I regret it?”
Izuku just shrugs slightly. Katsuki sighs, though it’s more fond than anything else, and ducks down to kiss his head softly.
“No. I don’t regret it. Izuku you could ask me to help you bury a body and I’d do it without an ounce of regret and then fuck you stupid when we get away with it. Which we would, by the way, because of me. You’re too anxious to get away with that shit without me.”
Izuku laughs softly, hiding his face in Katsuki's stomach as his shoulders shake. “I wanna argue that but you’re probably right.”
“I’m always fuckin right.”
“Yeah. I know.”
Izuku tilts his head up, looking at Katsuki with a look of pure adoration. His boyfriend just scoffs before just flicking his forehead gently. “Get out of this, ok? We’re fine. I don’t regret shit. In fact, fuck, I can’t wait to do that shit again. Felt fuckin amazing.”
Izuku blushes but nods gently. He sits up enough to kiss Katsuki softly. “Thank you Kachaan. I love you.”
“Yeah whatever. Now shut up and take a nap or something. I don’t wanna hear shit about your ass hurting later.”
“Ok Kachaan.” Izuku says with a smile as he lays his head back down and shuts his eyes.
“Oi, I mean it shithead.”
“Ok Kachaan.”
Katsuki tsks but lets it go, pulling him closer and burying his face in Izuku's curls. Warm hands rub soothingly at the base of Izuku's spine, gently working out the aches and tension. It only serves to lull Izuku closer to sleep. His mind is blissfully silent and for the first time in a long time there isn’t an ounce of tension in his anxious body. And as Izuku drifts off to sleep, curled against the love of his life and freshly fucked into bliss, he has only one thought.
‘With Kachaan by my side, I know I’ll be ok.’
