Work Text:
It's been a year since Katsuki finished the suit for Izuku and got his heart broken in more ways than he could count when he started a relationship with Ochako but a month ago, they broke up.
They ended on good terms saying that it's better if they just stay friends. At least, that’s what they told the public. One of the reasons that no one actually knows is that Izuku broke up with her because he is in love with someone else. And that someone is no one other than Katsuki fucking Bakugou.
He isn’t heartbroken over the break-up but sometimes he wished that he didn’t because now he comes home every night to an empty apartment, wishing that it was Katsuki that would greet him. Sometimes, on the really bad days, he cries silently in bed for a future that will never happen.
Katsuki would never admit it, but he was fucking thrilled when he heard that Deku and Ochako broke up. He realized that he was in love with the nerd when he said fuck you to the grim reaper back when he was seventeen.
Of course, he never said that or anything. But when he found out that the nerd had asked her out right after he had given him the suit, let’s just say that his friends weren’t exactly feeling safe in his car when he drove them home that night.
Deku told him that they had ended on good terms and that there was no animosity between them. In fact, they're still friends. So why did Katsuki sometimes see him in the morning with puffy red eyes, eyebags and a bedhead that could give a bird’s nest a run for its money. The guy looked like he just ran over his own puppy and cried about it for the whole night.
Katsuki, the curious fucking brat that he is according to his lovely mother, decided that he had to find out. He waited until Kirishima proposed a bar night before telling him his plan. That’s how they came up with inviting the whole class for a karaoke night.
Right now, Katsuki is sitting in the booth, listening to the girls drunkenly giggle into the microphone as they take an attempt to sing Firework from Katy Perry, watching Izuku down one drink after another. Normally he would’ve stopped him after a few because Izuku has no filter at all when he is drunk but now he wants to kind of use this opportunity to find out why Izuku has been acting so off lately.
He would never take advantage of Deku, it's just alcohol and the nerd got an outrageous tolerance. And even if it takes a lot to get him drunk, when he is, the floodgates are wide open.
“Kacchan,” he blinks out of his thoughts when he hears the pathetic whine coming from the other side of the booth. “Why are you staring at me?”
“You look stupid,” he grunted. And Deku really did. He was hanging half over the table, a dozen empty glasses in front of him, hair a mess, glasses askew on his nose and big ass fucking eyebags. Izuku huffed, his bangs blowing out of his face. “You fuckin’ good there, Deku?”
Izuku frowned a little, “Why? Don’t I look good?”
Cheeky shit. Katsuki grabbed his whiskey and took a sip. “Nah, you just look like you’re gonna fall of the table, dumbass.”
Izuku leaned forward. “I am not,” he slurred and then he paused, head tilting a little. “You’re so pretty, Kacchan,” he said softly. It was loud enough to be heard over the music and Katsuki almost choked on his own breath.
His ears were burning.
“Shut up, dork,” he muttered, taking another sip of his drink in hopes that he could brush his blush off as it being from the alcohol.
Izuku’s expression didn’t change but he did move closer. “Do you know why I broke up with Ochako?” he asked lowly.
Katsuki almost snorted because what kind of question is that.
When the promised couple broke up a month ago, it was all over the news. Everyone was angry, especially at Izuku. All of Japan thought that he did something scandalous ─ pages and pages were written with conspiracies about what he might have done, it was outrageous.
When it came out that Izuku was the one to break up with her, Japan turned their anger to Ochako. She was harassed while patrolling by people calling her everything in the book. Katsuki had to see it first-hand sometimes when he had to patrol with her and even if he was heartbroken to no end that Izuku chose her, he still told those nosy fuckers in a few colorful words to kindly fuck off.
Two weeks after their break-up, they were asked by Hero Talks to come to the show for an interview. It was requested by both their PR agents so they could clear the air on everything.
It went…not as expected. The host clearly had a thing for Izuku in the way she barely asked Ochako anything and tried to hopelessly flirt with him. Deku wasn’t deterred and actually gave Ochako the opportunity to answer half of the questions that were directed at him. Later that night he also called Katsuki to rant at him about how unprofessional the host was.
Katsuki had watched the show with all of Japan and he had to agree.
The blonde really respects Ochako for how she can bounce back when things get in her way ─ take the sports festival from first year for example. Even if his idiots insisted on her being some ‘fragile girl’, he absolutely did not see her like that. He's always told himself never to underestimate an opponent and he was glad he didn’t when she also didn’t hold back.
So of course, he was there for the girl even when knowing that she and Izuku might have had everything Katsuki wanted with him. How did it feel to be in his arms at night, to wake up with his sweet kisses, to watch him tremendously fail in the kitchen and laughing about it. His hands, God those hands.
How would it feel to have them caress over his body instead of hers, to have them worship him like something precious, like something beautiful. How would it feel to have those lips all over his body, raising goosebumps from where they leave a trail of love.
He can definitely admit that he is jealous that she got to see that side of him first but what right does he have, he doesn’t even have the fucking balls to ask him out, let alone ask him to be his boyfriend and tell him how head over ass he is for the green dork.
He shakes his head and looks away from those imploring eyes, looking down at his drink instead.
He can't think of that, Izuku would never be with him ─ he might’ve forgiven him for how he treated him during their childhood, but the pain was still real. Katsuki literally told him to kill himself! Yeah, he can't let himself think about a future with Izuku, it’ll only end up in him watching from the sidelines how Deku finds someone else, someone actually worthy of him.
He's also scared that he might taint the guy. The nerd is a saint ─ an angel sent from the heavens above. How he treats the kids that ask for a photo or an autograph when they patrol together, how he converses with elderly like they are something that he would think about a week later and then rehearse it to his friends.
And oh, his friends. How he helped Shoto overcome his fear of becoming his father and really embracing that he is his own person and then afterwards helping him actually find himself. How he helped Ochako with her quirk from time to time so she wouldn’t throw up after a couple of pounds of lifting something. How he helped change Iida’s hero suit to make it more efficient and movable while still remaining speed and his brother’s heroism. How he helped Tsuyu become her own hero and helped her confidence.
And just so much more for the whole class.
Yes, the nerd has been by his side for his whole life and never changed in how he is…now that he thinks about it, Izuku did change. He changed in middle school when Katsuki bullying went from bad to worse, and it's especially prominent how that affected him when Izuku would shy away from the class back when they first started UA.
And that’s just all the more reason why Katsuki shouldn’t say anything about how smitten he is over his nerd. About how he loves to see those eyes shine, how delicate those hands are even when they are bigger than his and mangled with scars, how his smile lights up the whole room, hell. How his whole presence just lifts everyone’s spirits as soon as he walks in a room.
And of course, there are moments that only Katsuki has seen. Those nights where he showed up at his door when he couldn’t save someone, when he wanted to listen to his heartbeat after a panic attack from a nightmare, when he always picks up the phone when Katsuki called for whatever reason, even if it is the middle of the night.
Yeah…Katsuki really doesn’t deserve him.
So, he just shrugs and takes a sip from his drink again. “In that interview you said that you’re just better off as friends,” he mumbled, his mood now simmered down when he started to think about everything that could’ve happened and definitely won't happen.
“I did say that didn’t I,” Izuku muttered, a light edge to his tone. Katsuki dares to look up and is immediately enraptured in those irresistible eyes. They are boring into him with an intensity like never before. They flick down and Izuku bites his bottom lip before locking his eyes back on searing vermilions again. “That’s also what I told her.”
Katsuki can't help it; he is but a human and fuck if he isn’t curious as to what else Izuku has to say. He puts his glass down and folds his arms over the table, leaning forward and leveling him with an unimpressed look. “What else, Izuku?”
They are the only ones in the booth right now, orbiting in their own universe as the rest of their friends are fighting over who’s next to sing, what drinks to get or just dancing to the music.
Izuku’s eyes dilate when he hears his name coming from his lips but before he can say anything, Ochako slides in next to him, shamelessly splaying half her body over his. “Dekuuu!” she slurs, obviously just a tad bit over her limit, “You gonna sing a song?!”
Never once did Izuku look away from Katsuki. “Sure Ocha, c’mon.” They get out of the booth, Katsuki looking at their retreating backs. Ochako has her arm interlinked through Deku as they make their way to…the bar? What are they doing there? He narrows his eyes and watches them sit down. Weird.
Izuku calls over the bartender and orders a water while Ochako doesn’t order anything. He wanted to drink something first before going on stage. He isn’t drunk per se because of his fast metabolism, but with what he was going to say to Katsuki, he might have to get a little bit less buzzed before doing it.
“So, Deku.” He looks over at Ochako as the bartender sets the glass down on a napkin in front of him. “We haven’t really talked in a while…how’s it going?” she asks, still leaning on him by the way.
He doesn’t really mind though; she’s aways been a tactile person. “Good actually.” He downs the water halfway before turning to her. “How are you?”
She sighs and puts her head on his shoulder, “Still feels weird but…it actually feels better.”
“Yeah…I get that,” he mutters, looking at the way the condense on the glass slides down onto the napkin. “I’m sorry.”
She lifts her head. “For what?” she questions. “We both agreed that it's better; I’m still hung up on Himiko, and you just love me as a friend, no need to apologize.” She sounds more sober than before, which is good because if he is going to be honest with her then he wants her to remember.
“For leading you on,” he sighs, still looking at his glass. “And also, for using you.”
Now she looks like she never had a drop of alcohol tonight. “‘Using’ me? Deku, what are you talking about?”
He sighs again and turns his head to her. He feels really bad about what he is going to say but it needs to be said, it's been weighing on him for the past year and even more since he broke up with her. “They were right about one thing.” She knows exactly what he's talking about and her eyes widen. “I’m in love with someone else.”
He can see a lot of emotions in those chocolate brown eyes; confusion, hurt, relief. But the one that stands out the most is realization, not in a bad way just…something she had been expecting for a while and already came to accept. “Yeah…I know.”
He almost falls off the barstool. “What?”
“Deku you−” she smiles gently and lays her hand on his forearm, squeezing it. “I see the way you look at him ─ your eyes say it all. It's Katsuki right?” His jaw drops. “I’ve known for a while,” she continues. “I was just so happy that you gave me a chance, but when I still saw that same look in your eyes when you looked at him,” she sighs. “I was okay when you broke up with me because I just want you to be happy.”
He leans forward and pulls her into a hug. “I’m sorry.”
“It's okay.” She holds him tighter. “It's better for both of us.” She pulls away. “Now go get your man alright. And if he says no or hurts you I'll show him a close up of the sun.”
He laughs wetly, wiping his eyes and nodding his head. “Love you, Ocha,” he says, kissing her cheek before standing up.
“Love you, too, Deku.”
Katsuki's stomach drops when he sees him kiss her cheek. Are they getting back together? Wait…he's walking away. What the hell is happening? First he sees her fucking plastered at his side like Velcro, then they are talking some, then he pulls her into a hug and kisses her cheek before just…leaving her and walking to the karaoke stage. Oh wait…she’s following him.
He downs his whiskey and squeezes his eyes shut. He knew he never had the chance. When did he get his hopes up and why did he let his heart create a hole that is Izuku Midoriya.
The club music dies down and in place started a deep bass. The next thing Katsuki noticed was Izuku’s voice. His eyes snapped open and he looked over at the stage where Izuku was standing in all his nerdy glory. The other was staring right at Katsuki while he sang the first line.
I’m so into you
I can barely breathe
Izuku starts to tap his foot onto the stage to the beat.
And all I wanna do
Is to fall in deep
You could say that Katsuki's jaw was on the table. What the fuck is happening? Now Izuku starts to snap his fingers to the beat, the rest of their class joining in.
But close ain’t close enough
Till we cross the line, hey, yeah
Izuku took his free hand to hold the mic with both, staring intensely into Katsuki's eyes as he started to sway his hips. Katsuki is sitting there frozen, jaw slack and eyes wide.
So name a game to play
And I'll roll the dice, hey
The song picked up its beat and Izuku took the mic of the stand, setting it aside, and walking forward on the stage, his eyes still locked on Katsuki's.
Oh, baby, look what you started
The temperatures rising in here
Is this gonna happen
Been waiting and waiting for you to make a move (ooh)
He now reaches the end of the stage and starts to descend the stairs.
Before I make a move (ooh)
As he reaches the end of the steps, the music is picking up again and Katsuki can do absolutely nothing as he watches Izuku start to walk towards him while singing the next lines.
So, baby, come light me up
And maybe I'll let you on it
Izuku reaches Katsuki and takes his hand.
A little bit dangerous
But, baby, that’s how I want it
Izuku tugs at his hand and walks back to the stage with Katsuki in tow who is still gobsmacked at all of…this. He looks at the stage and in the middle is a chair. Where the hell did that come from?
A little less conversation and a little more touch my body
They walk up the stairs and onto the stage before Katsuki is pushed into the chair by Izuku.
‘Cause I’m so into you, into you, into you
He sings with his hand still on Katsuki's chest, smiling innocently before taking a few steps back and grabbing the mic stand again. His back is turned to the class while Katsuki gets to see everything the walking wet dream is doing right now.
Got everyone watchin’ us
So, baby, let’s keep it secret
The mic is back on the stand, so Izuku’s hands are now free. Katsuki's own tighten on his jeans when he starts to unbutton his shirt.
A little bit scandalous
But, baby, don’t let them see it
Katsuki's eyes dart between Izuku’s eyes and his chest that is now getting more exposed until the last button is loose. The shirt falls open and Katsuki cannot take his eyes off the fucking sight before him.
A little less conversation and a little more touch my body
Izuku takes the mic again and walks to Katsuki. He takes his hand and puts it directly on those defined pecs that are adorned with freckles, and a real fucking turn on from the scars. Izuku lets his hand go but he keeps it there. Then the nerd puts a finger under his chin to tilt his head up, looking him directly in his eyes.
‘Cause I’m so into you, into you, into you
Ooh, yeah
Izuku steps away and starts circling him, tracing his hand over his shoulder as he walks behind him.
This could take some time, hey
When he is standing behind him, he leans down to sing right next to his ear.
I made too many mistakes
The fucking tease softly bites his earlobe causing the blonde to tilt his head back and spreads his legs wider, hands clenching on his lap. Izuku starts circling him again, hand still trailing over his shoulder and even through the fabric of his shirt, it feels like it leaves molten lava in its wake.
Better get this right, right, baby
And then the fucking shit plops down on his lap, ass full on his already semi hard cock, back to chest, and lean his head on his shoulder.
Oh, baby, look what you started
The temperatures rising in here
Izuku puts his free hand on the back of his neck and grinds his ass down on his crotch. Katsuki groans and puts his hands on his hips, guiding his movements. He's fully hard now.
Is this gonna happen?
Been waiting for you to make a move (ooh)
Izuku looks to the side and locks eyes with him.
Before I make a move (ooh)
Izuku closes his eyes and leans his head back on his shoulder. Taking one of Katsuki's hands, he puts it on his chest before gripping the back of the blonde’s head again.
So, baby, come light me up
And maybe I’ll let you on it
He spreads his legs, ass still moving in sensual circles on his throbbing cock.
A little bit dangerous
But, baby, that’s how I want it
Katsuki is still holding his hip with one hand, roaming his other hand over his chest as Izuku sits up. It feels as if someone puts an ice cube directly on his neck as soon as that hand leaves his skin.
A little less conversation and a little more touch my body
Izuku starts to lean forward while looking over his shoulder, putting his ass on full display for Katsuki and fuck he's drooling. It just looks so good like this, holy shit.
Cause I’m so into you, into you, into you
Izuku stands up and starts to circle him again.
Got everyone watching us
When he's behind him, he leans down again just like before to sing in his ear.
So, baby, let’s keep it secret.
His free hand whispers over his shoulder and over his chest, full on groping his peck when he reaches them. Katsuki has to bite his lip to stop the moan stuck in his throat from coming out when a finger graces his nipple.
A little bit scandalous
But, baby, don’t let them see it
Izuku slides his hand to his neck and holds it, not tightly, just a weight resting around the heated skin like a necklace. Katsuki closes his eyes at the sensation, never has he felt this good, the weight making his head feel fuzzy and his body floating.
A little less conversation and a little more touch my body
Katsuki is panting now ─ the voice next to his ear, the hand around his neck, the arousal creeping up his spine ─ it's almost too much. Fuck is he going to cum?! Like this?!
Cause I’m so into you, into you, into you
His eyes snap open when Izuku’s whole presence just leaves. He looks around while the beat of the song changes and sees him walking back to the front of the stage.
Tell me what you came here for
He's standing with his back to Katsuki as he sings to the whole class who are all staring with their mouths dropped and eyes wide at Katsuki and Izuku.
Cause I can't, I can't wait no more
Izuku looks over his shoulder and his eyes lock directly on Katsuki's wild ones.
I’m on the edge with no control
Izuku turns around then ─ their gazes still locked ─ and walks to Katsuki again.
And I need, I need you to know, you to know
Oh, yeah
The minx stops in front of him in between his legs when the beat picks up again for the last part of the song.
So, baby, come light me up
And maybe I'll let you on it
Izuku takes one of Katsuki's hands and puts it on his hip before putting the other right in the middle of his chiseled chest.
A little bit dangerous
But, baby, that’s how I want it
Katsuki's hand flexes on his hip while the other starts to touch every bit of freckled skin he can see in front of him.
A little less conversation and a little more touch my body
He looks at his face while doing it and he can see in his eyes how blown out his pupils are and swirling in that black void are so many emotions; lust, adoration, admiration, nostalgia, and above all, love. Izuku tilts his head down, he does the same and his eyes widen when he sees it.
Cause I’m so into you, into you, into you
Izuku is fucking hard. In his slacks is definitely evidence of his own arousal. But that’s not all ─ the nerd is huge. It's mostly held back by the confines of the fabric, but Katsuki can see that Izuku is fucking blessed.
Got everyone watching us
So baby let’s keep it secret
Katsuki looks back up at his face again when he sees him move his hand up. Izuku has a finger in front of his lips while giving him a wink.
A little bit scandalous
But, baby, don’t let them see it
He can actually see Izuku’s eyes harden when he sings that line. Right. He forgot how fucking possessive he is of him.
A little less conversation and a little more touch my body
Izuku moves his hand to the collar of his shirt and moves it to the side to let it drop over his shoulder. That wide, muscular shoulder littered with freckles stares at him. He's heaving like a fucking animal, he needs to touch it, to bite it, to dig his fucking nails into it as he's being rammed into the mattress. Wait−
Cause I’m so into you, into you, into you
And then the best thing ever happens ─ Izuku sits in his fucking lap. Their hard cocks brush together though the fabric and Katsuki bites his lip until he feels the skin break. Izuku’s free hand is roaming over Katsuki's chest and shoulders like he owns him and he probably does.
So come light me up
So come light me up, my baby
Izuku is staring directly into his eyes when he calls him that pet name and Katsuki can feel his face heat up even more. How the fuck is he supposed to survive the rest of the night?
Little dangerous
A little dangerous, my baby (how I want it)
Izuku grasps his chin again and brings their faces closer. Katsuki's eyes flutter when he feels Izuku warm breath fan over his cheeks while he sings. Izuku’s eyes flick to his lips as his eyes begin to go lower until they are heavily lidded, the green of his irises almost fully consumed by the black of his pupils.
A little less conversation and a little more touch my body
And this time Katsuki doesn’t wait for Izuku to guide his hands ─ he does it himself. He puts them on those slim hips and moves them in a circle, all while holding eye contact with Izuku who smirks and starts to move with his hands.
Cause I’m so into you, into you, into you (I’m so into you)
The song stops and Izuku literally drops the fucking mic. They're both breathing hard, panting almost as they stare into each other’s souls. Katsuki's hands flex on those hips. “Izuku…” he breathes. “What are you…” He can't finish the question because Izuku suddenly goes rigid.
He stutters out some muttered words and then jumps off his lap, making a fucking beeline to the entrance of the bar as if his ass was on fire. Katsuki stares after him, stunned as he wrenches the door open and gets out, Ochako following him a few seconds later.
He jolts out of his trance when a hand lands on his shoulder. He looks over and sees Kirishima standing next to him with a tense smile. “Go after him and tell him.”
Katsuki didn’t need to be told twice; he stood up and ran to the door.
Back when Izuku and Ochako got together, Katsuki had the biggest fucking crash out of his life.
After he dropped off his friends except for Kirishima, he rode to a cliff on the edge of the city and let himself break down ─ seven years of stress, planning, feelings, hope, restless nights, hunger, and just everything to make sure that the suit was fucking perfect, came crashing down on him.
He fucking sobbed in his car while Kirishima held him, the redhead being the only one to know how hopelessly in love he is with his nerd. He screamed at how it wasn’t fair and then sobbed again because he knew that he didn’t deserve Izuku, not after how he treated him for ten years when they were kids, not after what he said.
He hit Kirishima’s hardened body over and over again, trying to let out everything that he was feeling instead of bottling it up like he had been doing his whole life.
He clung to his best friends while he begged for Izuku to not leave him, to not cast him aside even if he deserved it. God, it felt as if his heart was exploded again but this time it hurt worse because he was actually alive enough to properly feel it and fuck if it wasn’t the worst feeling ever.
After that he took a week off.
He stayed in bed while Kirishima took care of everything. He didn’t eat unless forced, drank less, never checked his phone, never answered the door. At night he cried until his throat was raw and his eyes were drained from tears.
Deku showed up on the third day of his absence.
Kirishima had told him that he had sent the nerd away by telling him that the stress of preparing the suit caught up to him and he needed rest. Izuku wanted to see him for himself of course, but Kirishima insisted that he was fine, he just needed rest.
He wasn’t fine and no amount of rest could lessen the pain he was feeling.
When he did check his phone on the fifth day, the first thing he saw was that Izuku and Ochako’s relationship already got out. And even if it hurt him to actually have visible proof of it, he couldn’t help but be confused because that wasn’t like Izuku at all. The dork guards his private life like it could actually be the end of the world of he didn’t have that boundary anymore.
Apparently, a reporter saw them on a date and took a picture then had the stupid idea to post it on Hero Star and started a whole controversial discussion in all of Japan about if they are in a relationship or not. They only confirmed it to get them off their back.
And for some reason it was what made Katsuki get out of bed for the first time in five days aside from going to the bathroom. He had walked into the living room and sat down next to the redhead sitting on his couch. Kirishima didn’t say anything, just turned the TV on and put on a Silver Age All Might movie.
On the eighth day after giving the suit, he got back to work, and things were just like before only now he has so much more freedom without the suit weighing on his shoulder. But now there was a new weight, and it was almost ten times heavier.
It caused him to sometimes drift off to the edge of the world and just stare out of the window of his car until the sun came back up. It caused him to sometimes cry himself to sleep while looking at pictures and videos of when life used to be just him and Izuku. It caused him to treat villains way too violent on some bad days when he woke up to a nightmare of Izuku getting married to someone that wasn’t him.
It almost caused his body to give up when he landed in the hospital after he collapsed and the doctor told him that he had been starving himself.
Izuku found out about that one and actually begged him to tell him what’s wrong. Right. As if he could ever understand.
He took him off his emergency contact list that day.
Four months after he gave the suit, things miraculously started to get better.
When Izuku and Ochako’s relationship wasn’t so new anymore, Izuku invited him to the classroom more. They started patrolling together, and sometimes even had dinner. Katsuki even had moments where he forgot that the nerd was in a relationship and that speck of hope would build in his chest only to be crushed when he had a nightmare that same night.
And yet ten seconds ago, Izuku was serenading the fuck out of him and now Katsuki is chasing after him like he had been doing for the last ten years.
The stale air of late June hit him in the face as he ran out the door. He stopped and looked around. Izuku was nowhere to be found.
Then the distinct smell of cigarettes hit his nose. It was a long shot, but he followed the putrid scent and rounded a corner. There, leaning against the side of the bar was Izuku, taking to Ochako. Shirt still open and glasses in one hand while the other held a cigarette.
He stepped back out of sight around the corner when he heard them talking.
“…after what happened.” He heard Izuku say.
A sigh followed. “Izuku, you need to seriously see past those things and just tell him.”
“I can't!” Izuku groaned. “He didn’t even know what I was trying to say!”
“He tried to ask but you ran! Like always!”
He could only hear cars passing on the street for a few seconds.
“…I know Ocha. I’m just−” A sigh. “What if he already moved on?”
Katsuki's eyes grew wide and he felt his whole body freeze from where he was leaning against the cold stone wall. His ears focused back on the conversation.
“What do you mean, Zu?”
Another sigh. “Kirishima told me.”
Katsuki's heart dropped and fell out of his ass only to smack onto the dirty ground. His knees almost buckled out from under him, and he was panting as if he just ran a marathon. He slapped a hand over his mouth to prevent any sound from coming out and tried to listen to Izuku over his own heartbeat pounding in his ears.
“After we broke up, I went to him and asked him if I ever had a chance. That is when he told me about everything that Kacchan went through after we got together. He also told me that he would never tell me if Kacchan hadn’t almost died back then.”
Fuck Kirishima and his big ass fucking golden retriever heart. Of course, the idiot wouldn’t be able to keep his damn mouth shut.
He heard a loud gasp. “Deku…what are you talking about?”
“Kacchan he…” The sound of a lighter flicking on reverberated through the walls of the alley. “He was starving himself, barely holding himself together on the field, didn’t come out of bed for the first week after we got together. Even the doctor told him that he can't keep going like this. Kirishima begged me that day to spend more time with him that day and I did…a few months later,” he mumbled.
“Deku…”
“I mean ─ fuck ─ he almost died and when I started hanging out with him again, it just made me realize that I’m still so fucking in love with him and now I’m scared that he already moved on even if I made myself look pathetic in there.”
Katsuki slid down the wall and tucked his legs to his chest, wrapping his arms around them and burying his face in his knees. He listened to the cries of the love of his life as every moment of the past year flashed before his eyes. And then every moment those eyes were on him during his pathetic twenty-seven years of living slammed into the forefront of his mind.
The tears slipped down his cheeks when the realization hit harder than anything he had even felt before.
Izuku loves him.
Even if he got into a relationship with someone else, he broke up with her because he loved him. And now he thinks that Katsuki could move on from him. His heart hurts at the thought of it.
“…back soon?” His ears picked up Ochako’s voice.
“Yeah…just need a few minutes alone.”
That’s all he heard before he scrambled away from his hiding spot and darted around the corner on the other side of the building. He can't let anyone see him like this. He listened to the door close and resolve as hard as steel settled in his chest. Dusting himself off, he didn’t bother to wipe his cheeks dry and marched to Izuku.
Izuku tilted his head back until it hit the wall he was leaning against and took another drag of his cig. “Fuck…” he croaked as the smoke passed his lips. Apparently he shouldn’t have gotten that glass of water because he probably wouldn’t have run otherwise. Fuck his metabolism, seriously. He isn’t even a little bit buzzed anymore, and it makes it all just so much worse.
He looked down at the cancer stick between his fingers.
It's a habit he had picked up after he lost One for All. Only a few people know about it; Kacchan, Ochako, Shoto. He didn’t want anyone else to find out about it because he himself hates it more than anything.
Back when he found out that he lost his mom during the first war, he heavily considered it. His dad used to smoke, and he found his old stash hidden in the back of the kitchen cabinet. Sometimes he would sit in bed and just stare at it, not knowing what would happen if he started.
Instead of lighting one up, he ran. He had this ideology about how it could defeat All for One but apparently it didn’t work. Then Kacchan apologized and he allowed himself to properly grieve his mother. Until the second war happened.
Things went downhill from there for him.
Of course there were some positive aspects. Like Kacchan being his friends again, no more villains attacking them every week like it was another Wednesday, he was treated as an equal.
But there was still that lingering fear of when the last embers of One for All would snuff out and when they did, he felt…empty. As if a part of his being had left with it. He missed the bickering of the former users, the comfort they brought him, the warmth of it flowing through his veins, the adrenaline of soaring though the skies.
One night he grabbed one of the packs of cigarettes, a lighter, and went to the roof of the heights alliance building. They were in their third year, halfway done and packed with internships. This was one of those weeks where he would have a break and only school to focus on.
He had set down on the edge of a building and felt a nauseating wave of nostalgia. How many times did he stare at the roof of a building from the ground up when he was in middle school?
He had laughed at it back then but now? Now it feels as if it would solve everything.
That’s the first time he had it up a cigarette. He choked, violently. At first he hated it, but when he started to get the hang of it, the sweet feeling of the nicotine rush made his head finally quiet for the first time in his life. The smoke settling in his lungs made him feel as if he could breathe for once, even if it destroyed him from the inside out.
Back then he would only sneak a cig in here and there and it wasn’t that big of a deal.
Kacchan had found out about it when he had snuck away during graduation when the stress got too high. The blonde had demanded that he’d stop, but when Izuku had explained why he started in the first place, he had nothing to say anymore. Doesn’t mean that he stopped asking him to stop though.
After that, he started to smoke less and less and he thought that he would actually quit.
Until he started dating Ochako.
It wasn’t Ochako ─ she was a great girlfriend. It's just when he also started to hang out more with Kacchan and realized that he was still in love with the hothead, that’s when it started to get really bad. He would wake up and crave one, eat and smoke one right after. He’d even wake up in the middle of the night to sit on his balcony and stare at the city while the smoke circled around him like a blanket before being carried away with the wind.
He sighs and brings it to his lips.
The smoke was settling in his lungs when he heard footsteps coming towards him. At first he thought that Ochako might have come back until he recognized them. Footsteps that he would know even if it was in the loudest room ─ even if it were the most silent steps its owner would be able to make.
He looks up and sees Kacchan marching towards him.
Katsuki sees him look up at him ─ his eyes red rimmed behind his glasses in the low hue of the streetlights, his hair more wild than normal and the cursed fucking cigarette resting between his fingers. He can't even find it in himself to care about that small detail ─ he just keeps waking to the nerd, his cheeks still wet and cold from the tears from earlier, the wind biting at the skin.
When they are finally face to face, less than a foot between them, Izuku opens his mouth, a bit of smoke coming out from between those dry lips. Katsuki licks his own and raises his hand to clamp around the back of Izuku’s neck, feeling goosebumps rise under his sweaty palm, to drag him down and crash his mouth against his.
Back in third year Izuku finally got his growth spurt and exceeded Katsuki's height by a few inches. He bitched about it relentlessly, but when he stopped, he figured that he actually liked the fact that Izuku was taller than him.
Izuku’s eyes blow wide when he feels the sensation of Katsuki's wet and soft lips against his dry and cracked ones. For a moment he doesn’t move, scared that any move he makes might wake him up from this familiar dream, until he decides to just let his eyes flutter close and relax in the feeling coursing through his veins right now.
It feels as if fire was crackling between them ─ an inferno so bright it could light up their whole worlds.
He lets the cig drop from his fingers to grab hold of Katsuki's small waist, Katsuki's other hand coming up to cup his cheek while their lips glide together. Izuku tilts his head and flexes his hands, making Katsuki gasp against his mouth. Izuku takes that as an opportunity to plunge his tongue inside, the muscle exploring that sweet mouth with fervor.
Katsuki is slightly shaking against him, his hand on his neck gripping tightly on the small hairs there, while fighting back just as hard against the tongue pushing against his own, trying to win a losing battle.
Katsuki's had his fair share of hook ups during his hero career, but never once has he felt like this; like he wants to drop to his knees and obey Izuku’s every command. Wanting to worship that huge cock like it's his last meal ─ devouring it and choking on it while Izuku uses him like his own fuck toy.
The thought makes him whimper just as Izuku bites on his bottom lip and sucks on his tongue right after. If it wasn’t for Izuku’s hands on his waist then his knees would’ve buckled out from under him ─ it's almost too much for him to handle right now.
His palms are fuckin sensitive because of his quirk so when he registers Izuku’s scar brushing against it from the movements of fucking devouring his mouth, his hole involuntarily clenches as if he could hold onto something that wasn’t there.
Fuck. He's never done anything with it ─ he always topped ─ and like fuck if he's going to let Izuku be the change that will tilt his whole world on its axis and leave him to gather the pieces of himself when he fell apart at the hands of one Izuku fucking Midoriya.
But shit if it doesn’t make his stomach cramp from the onslaught of arousal when his mind provides him with an image of him being rammed into the mattress by Izuku, being bend over his desk and his insides being rearranged while he tries to be quiet, bouncing on that cock as his hips are bruised by Izuku’s grip.
He whines in his mouth when he feels his boxers getting wet from the amount of precum leaking from his dick. “Izuku…”
The fucking nerd just hums and pulls away to start licking and sucking at his neck, pushing him back against the wall to jam his thick thigh between Katsuki's legs so he could rut down on it.
Katsuki throws his head back when he feels Izuku’s teeth brush against his jugular, one of his hands going down to grab his thigh and circle his hips against it, his cock getting the friction it’s been begging for ever since Izuku got up on that stage and started to fucking serenate him.
Izuku pulls off his neck with a wet pop and lays his forehead on his shoulder to watch Katsuki get off on his thigh. “That’s right, Kacchan. Keep going,” he rasps out, completely enamored on what’s happening right now.
The words make Katsuki whine loudly and press harder against the thick thigh between his legs. “Ngh, Izuku! Please,” he begs, not even knowing what for. All he knows is that he wants to cum right here, right now.
Izuku smirks, still watching as Katsuki's hand tightens and his hips fasten their movements. “Yeah? What is it, baby?”
Katsuki whimpers at the nickname and his hips buck harshly at the tone in his voice. He's so fucking close already.
Then, Izuku slides his hands down to grab his hips and guides his movements. The change has Katsuki gasping for air as he throws his head back again, hitting the wall with a dull thud. He grits his teeth as he focuses on chasing his orgasm.
Izuku’s mouth falls open and drool slips out, landing on his thigh. Fuck, Katsuki looks so good like this. Of course, Izuku has always known where he stands when it comes to his sexual preferences, but he’d never expect Katsuki to become this docile as soon as he got his hands on him.
Kacchan is whining loudly and desperately while rutting his thigh like a bitch in heat, one hand gripping Izuku’s thigh while the other is still holding on to the back of his neck, as if it's the only thing keeping him upright.
“Deku…!” Izuku snaps back to the present when he hears Katsuki whimper. When he registers what he said, he grips his hips tighter to stop his movement. Kacchan whines loudly and his nails dig in his neck as he looks down. “Wha−”
“You know how to address me, Kacchan.”
And fuck if that didn’t just make Katsuki want to just bend over right then and there to let Izuku have his way with him. He looks up a little and he can sweat sliding down between his abs. His eyes glaze over with an image of himself licking it up. His mind replays those words in his head over and over again like a broken record until he gasps. “Izuku!”
But Izuku doesn’t let him move even an inch no matter how much he tries to push against his grip to get that friction back. “C’mon Kacchan, you know what I mean,” Izuku whispers in his ear. His voice demanding yet soft and it makes Katsuki's insides twist even more. Katsuki's face heats up with embarrassment and he shakes his head. “Yeah you do,” Izuku taunts, his grip tightening.
He does. God, he so does. He just can't look past his pride to actually say it but fuck if he doesn’t want to fucking cum. So, instead of denying Izuku the satisfaction, he grips his hair and wrenches his head from his shoulder to look him in the eyes.
His breath catches for a second when he sees his face. Izuku’s eyes are consumed by black; pupils dilated until there is almost no green left. His cheeks are flushed and his chin is wet from the drill leaking out of his mouth. But the most striking thing about what he sees is the raw, carnal desire swirling deep in those black voids.
It makes him go slack in his hold, the words tumbling past his lips without his permission before he can stop them. “Please…Daddy.”
Izuku’s eyes narrowed and a predatory smirk stretched his lips. “Good Boy.”
Katsuki choked on his moan when Izuku moved his hips up higher, causing him to have to stand on his tip toes. The friction slammed into him and knocked the wind from his lungs. “F-Fuck!” Izuku didn’t give him a second to catch his breath before he plunged his tongue down his throat.
Katsuki let’s go of his thigh to hold onto his neck, relying solely on Izuku to guide his movements and soon the buzz of his impending orgasm crept up his spine. Tears pricked at his closed eyes from the intensity.
Izuku pulled away slightly, their lips still touching. “C’mon Kacchan, be a Good Boy for Daddy and cum.” He said against his swollen lips before kissing him again, his tongue leaving almost no room for Katsuki's.
That did it.
Katsuki arched off the wall and keened highly, slightly muffled by Izuku’s mouth. His hips bucked wildly in his grip, nails scratching at his nape. Thick ropes of cum shot from his dick and into his boxers. It felt like electricity going through his whole body; his ears were ringing and his toes were tingling. White flashed behind his eyelids as he desperately held on to Izuku through every pulse.
When the last wave came after what felt like an eternity, he slumped completely into Izuku’s hold, his spine uncoiling and his grip loosening. Izuku pulled away from the kiss and caught him. “I got you,” he whispered, “I got you, baby.”
Katsuki wrapped his shaking arms around his neck and nuzzled against his collarbone. Izuku grabbed the backs of his thighs and hoisted him up, wrapping them around his waist as he started to walk to Katsuki's car. “Where your keys baby?” he whispered in his ear.
Katsuki shivered. “…pocket,” he grumbled, the aftereffects of the best orgasm of his life making his mind fuzzy. “Back.”
Izuku slid his hand to his ass just as he reached the car. He felt the keys in the pocket and grabbed them. Unlocking the car and opening the door, he sat Katsuki in the passenger seat and put the seat belt around him before walking to the driver’s seat and sitting down himself.
He started the car and backed out of the parking spot and entered the street, driving to Katsuki's apartment. He kept one hand on the wheel while the other rested on Katsuki’s thigh. He's still painfully hard but right now the talk they are about to have is more on his mind.
What just happened could just be a spur of the moment thing. Sure, Katsuki initiated it, but who knows if he actually does feel the same about Izuku. What if all that was just a mistake that would make or break their relationship forever.
His jaw clenched and his grip on the steering wheel tightened.
Tears prick at his eyes when he thinks about what Kirishima told him ─ Katsuki breaking down in the same car he is driving right now, the same seat he is sitting in, heart breaking on the same road he is driving on.
He wipes a hand over his face.
Looking over at Katsuki, he sees him sitting pliantly in his seat, totally satiated from his orgasm. Izuku can't help but smile. He can imagine Katsuki normally just being the same hothead he always is and not accepting aftercare. He hopes that he is the only one he can be this comfortable around, even after everything that has happened.
They arrive at Katsuki's apartment complex and Izuku pulls into the garage. He takes the entry card out of the glove box to scan it before finding a parking spot. After he finds one, he kills the engine and turns to Katsuki, hand on his thigh again after putting the card back. “Kacchan?” he calls out softy.
Katsuki made a soft sound and lolled his head to the side; his eyes are heavily lidded. “What?” he grumbled.
Izuku smiled and chuckled softly. “Let’s go inside yeah?”
Katsuki nodded and unbuckled the seatbelt. Izuku did the same before opening the door and stepping out, Katsuki following. Izuku walked around the car to get to Katsuki just as he looked like his knees would buckle out from under him. He wrapped an arm around his waist and almost instinctively, Katsuki leaned on him.
They walked to the elevator slowly. Katsuki was still leaning on him when it opened and they stepped inside. Something filled Izuku’s chest that he couldn’t name ─ he's been here hundreds of times and yet right now it felt as if this could either be the first time of something or the last time of everything.
They rode the elevator up to the 27th floor and Izuku’s mind was still racing. Fear settled somewhere deep in the back of his mind, stronger than ever before. He looked down at Katsuki and sighed, his hand on his waist tightening. Katsuki had his head on his chest and almost whole weight against him.
His face is relaxed, every mask and wall just gone. His eyes are closed in a way that looks like anything could happen and he would trust Izuku with his life blindly.
And that just made Izuku’s chest cave in.
Their whole lives flashed before his eyes.
Sometimes he still wonders when it all changed ─ the change of Katsuki being his best friend, to his bully, to his rival, to his best friend again and to more than he could ever express in words alone.
He can't remember when Katsuki started to think that Izuku thought he was superior to him when he wasn’t. Izuku always saw them as equals, no matter what. So, what was the one significant event that changed Katsuki's view of himself for over ten years?
But then again, Katsuki probably already moved on. Even after what just happened, even after Izuku is ready to lay his whole heart on the table and have him hold the knife, he’ll let Katsuki choose. Choose whether he wants to have a future with or without him.
It's a big choice but Izuku doesn’t know if he can bear not having Katsuki by his side for a third time.
The first time it was the unanswered questions that hurt.
The second time was his own choice that could’ve broken them.
The third time…
Izuku shakes his head and steps out of the elevator with Katsuki in his arms. He's not going to run away like he did every time he was confronted with his feelings for the blonde. They're going to talk ─ probably tomorrow ─ and then…he doesn’t know yet; anything could happen.
They reach the front door of the apartment and Izuku unlocks it, stepping inside. He closes it behind him, and they take their shoes off before walking to the bedroom. Laying Katsuki down on the bed, he starts to undress him. Katsuki is still like putty in his hands but now Izuku starts to think that it might be on purpose.
You see, Katsuki might say that he does everything himself and that he doesn’t need help and that might be true, but Izuku knows that deep down, Katsuki likes to be treated like he's something precious; like he's something to be treasured.
So, when Izuku was only in his boxers and Katsuki was Izuku’s shirt and his own boxers and they laid in bed, Katsuki immediately cuddled into his side, nuzzling his cheek on his peck and throwing a leg over his waist. Izuku put on hand in his spikes and held his thigh on his stomach with the other after taking his glasses off and putting them on the nightstand.
He dropped a slow kiss on his forehead. “Gonna talk tomorrow, ‘kay?” he whispered against the skin.
Katsuki nodded and nuzzled closer before his breathing evened out a few minutes later. Izuku kept carding his fingers through his hair until he too fell asleep.
The next morning, Katsuki had a hard as fuck time waking up. First of all, he just slept the best in years, and it was really fucking hot right now, even without his blanket. He tried to stretch his back only to have his movements restricted by a pair of arms. Wait−
His eyes flew open, suddenly wide awake. Last night slammed into him like a sledgehammer and his heart started pounding in his ears. Last night he…busted his nut…on Izuku’s thigh?! In a fucking alley?!
What. In the actual. Fuck.
He looks over his shoulder and the first one he sees is a mop of green curs. Next he registers the steady breath on his nape and the warm body behind him, fully encasing him. Lastly, he feels something poking at his ass. His breath hitched when he realized what it was. Then, a mischievous smirk grows on his face.
Time for some fucking payback.
He carefully turns around in his hold and pushes Izuku on his back, climbing on top of him while doing it − the nerd didn’t even stir from his slumber. This might be even easier than he thought.
He leaned down and started licking at his throat, slowly nibbling on the skin and sucking at the same spot, leaving a red splotch in its wake. He did that on a few places before he started to move down ─ crawling down his body and nipping at his chest. Izuku groaned softly and he stilled, staying like that until he was sure that he was still deep in his sleep.
He moved down further until he was face to face with Izuku’s erection. He grabbed the waistband of his boxers and tugged at it until his cock sprang free. Precum was already beading at the tip and it was an angry red from how hard it was. His mouth watered when he vaguely sees the veins throbbing from the blood streaming through it.
He wetted his lips and lapped at the precum, his eyes fluttering at the taste. It's salty and musky and so Izuku. He kept his eyes open, focused completely on how Izuku face scrunched from the feeling. Katsuki made himself more comfortable in between his legs when even more confidence settled in.
With one hand, he grabbed his length and started to really make the tip wet. Izuku’s breath hitched and got heavier immediately. He kept doing that until his saliva started to drip down his cock before taking more in his mouth.
The girth of it made his jaw ache instantly but he was determined to take it ─ he can suck a dick; it was just never one this big. Leave it to Izuku to exceed all of his expectations without even trying. Not like he is complaining. He already loves his cock and knows that he wouldn’t want anything else for the rest of his life.
He started bobbing his head, breathing through his nose when it reached the back of his throat, and held the rest with his hand, jerking him off at the same time. His eyes are locked on Izuku’s face, the face that is now flushed red with its mouth gaping open to let out heavy breaths.
He sees movement in his peripheral and feels one of Izuku’s hands on the back of his head. That gives him the right courage to take Izuku even deeper. He focused on his breathing and started to sink lower.
He almost chocked and gagged a few times, but he made it, almost doing a fucking victory lap every time Izuku’s hand twitched on his head whenever his throat convulsed around his cock.
He swallowed once around it and almost choked instantly when Izuku’s hips bucked. His eyes snapped up when he heard the most delicious sound coming from his lips. Pure resolve settled in his chest, and he started to move again.
Every time he got up, he swirled his tongue around the tip and went down again, rubbing the vein on the underside of his length with his tongue and swallowing as soon as his lips touched the dark green pubes.
He should be disgusted by the fact that Izuku keeps it long considering he makes sure that his own pubes are always trimmed but it weirdly turns him on more. Thinking about Izuku fucking his face and his spit coating those hairs makes his dick twitch. Fuck he's hard as a rock right now. And he's just sucking the nerd off! The fuck?!
Never mind that, he's on a mission to make Izuku cum the same way he tortured him last night. Hard.
The hand on the back of his head tightened even more and he sees Izuku’s eyes flutter open, so he starts to go faster. “Fuck, Kacchan,” Izuku groaned. He hummed around his cock and his hips stuttered wildly. Now both of his hands are on his head, making him go faster and deeper. “Shit,” Izuku hissed.
Once his lips touched his pubic bone again, he stayed there and swallowed. The cock twitched a few times before warm cum hit the back of his throat and Izuku cursed loudly, throwing his head back. He swallowed it all and only got off when Izuku pushed at his head, whining about the overstimulation.
He wiped his mouth with the back of his hand, panting heavily before climbing up Izuku’s body again and kissing him harshly. Izuku retaliated by shoving his tongue past his teeth and in his mouth, moaning loudly when he tasted himself. One of Izuku’s hands landed on his waist and pulled him closer, the other still gripping his hair.
Katsuki pulled back and smirked down at him. “Morning, Daddy.” he purred in his face.
Izuku’s eyes widened before they narrowed to slits and before he could think, he was on his back with Izuku hovering above him. Izuku leaned down to capture his mouth, and he eagerly kissed him back. When he tried to grab onto him, Izuku took his wrists and pinned them above his head with one hand, rendering him unable to move.
Izuku pulled away from his lips and started to suck at his throat. “Think that was funny?” he says as he nipped at his jugular.
Katsuki moaned and arched his back, pushing his own erection into Izuku’s. Wait− how is he hard again so soon? “Hah− w-what?”
Izuku’s free hand started to wander over his upper body like it was trying to map everything. “Think that was funny?” he repeated, moving his shirt off to expose his pecs. He dipped his head lower to start sucking at his nipple, pulling and pinching the other with his hand.
Katsuki threw his head back. “Fuck! Izuku!” he whined loudly.
Izuku pulled away with a wet pop and moved up to see his face. “Answer me,” he demanded with a tone to his voice that Katsuki recognized from last night and sent a shiver through his while body.
“I-I,” he stuttered. The fucks wrong with him? He never stutters! He cleared his throat and tried to give him a confident smirk, but he could feel how it was cracking at the edges. “Payback for last night. You like it?”
Izuku’s stare was unwavering. A smirk of his own grew on his face, way different from the one Katsuki tried to manage, and let his wrists go to hold his hips with both hands. “You want payback?” Before he could say anything, he was turned on his stomach, and his hips were lifted in the air.
His chest was flat to the bed while his ass was sticking out. “Wha−” Then his boxers were ripped away from him before he could even utter a full word. Confused at everything happening at once, he tried to look over his shoulder but was cut short from doing that when Izuku licked over his hole with his tongue.
He moaned loudly at the feeling because holy shit that felt good.
He wasn’t kidding about never doing anything like that before but fuck he's been missing out. Why did he convince himself that he was a top again? Or is it just with Izuku that he wants to let go of everything a beg to be fucking by the best cock in all of Japan.
“Fuck Kacchan. You taste so good.” Izuku hummed before he dived in again. he held onto his hips with an iron grip to keep him from moving away as he devoured his ass. At some point he started to pump his tongue in and out of his hole and Katsuki couldn’t stop moaning if he wanted to ─ it just felt fucking amazing.
An embarrassing whine left his throat when Izuku pulled away, and he was about to ask why he did that when he felt something else prodding at his ass. He was panting and drooling on the pillow when Izuku inserted his finger and started to move around. “Fuck! Yes, Izuku!” he slurred, high on the pleasure coursing through his body.
He screamed when that finger abruptly pulled out and he felt a slap on his ass cheek. “C’mon, Kacchan, you know what to call me,” Izuku taunted while massaging his ass.
Tears pricked at his eyes, and he let out a sob from desperation. “Please Izuku! Please, I wanna cum!”
Smack
Katsuki sobbed when Izuku slapped his ass again, the other side this time. His grip on the pillow was so tight, his knuckles have started to turn white, but he refuses to give in that easily. He pushed his hips into Izuku’s massaging hands.
He heard a sigh from behind him and then his hands were gone from him, Izuku’s body heat leaving with it. He heard him move around before the drawer of his nightstand was opened and he heard him rummaging around in there. Apparently, he found what he was looking for because the drawer was pushed shut before he felt Izuku’s hands on him again.
The snap of a bottle opening made him flinch and his shoulders tighten before he felt Izuku rub his hand over his spine. “Shh, it's okay.” The soothing voice made him relax into the sheets.
The hand left for a few seconds before he felt his fingers return to his hole. He mewled loudly, pushing his hips into the touch. Izuku chuckled lowly and kept rubbing his ass with his wet fingers. “You like it that much?” he said and pushed two fingers in this time, all the way to the last knuckle.
Katsuki moaned into the pillow and dug his nails into the fabric. The sensation of Izuku fucking and curling and scissoring his finger in his hole causes sweat to run up his back and his throat to make the most embarrassing sound he has ever made.
He choked on a sob and arched his back harshly when Izuku curled his fingers in a specific way and touched something deep inside him.
“Found it.”
Izuku watched as his fingers disappeared in Katsuki's ass. Watched as his hips pushed more against him with every push against his prostate, as his neck turned more red from the ecstasy, as Katsuki clawed at the pillow from the onslaught.
Drool is dripping down his chin. Katsuki is so fucking amazing like this, his head feels delirious. He felt his hole clench around his fingers, indicating that he is close to coming. “C’mon, Kacchan, you can do it.” he said with a smirk. He saw Katsuki nod into the pillow and he leaned over him, his chest touching his sweaty back.
He grabbed Katsuki by the roots of his hair and yanked his head to the side, making the man under him whimper. “I-Izuku.”
Izuku tilted his head down to whisper in his ear. “You know what to call me, baby.” he slowed his fingers and Katsuki whined in desperation. “I'll let you cum if you say it.”
He started to push another finger against the others and Katsuki choked on his next word. “D-Daddy!”
Izuku smirked and kissed his temple. “That’s my good boy,” he said as he pushed a third finger inside and started to really prod against his prostate. Katsuki moaned loudly, louder than before because it isn’t muffled by the pillow anymore, and came on the sheets, painting it white.
His hole clenched and pulsed around his fingers, almost making it hurt, but Izuku kept going to help him ride out his orgasm. As soon as Katsuki went limp and started to bitch about the overstimulation, he stopped moving them, not taking them out because that is just the worst feeling ever.
Katsuki collapsed on the bed, panting harshly and completely lax. Izuku kept kissing the side of his face and whispering praises in his ear. Faintly, he saw a small smile on his face while he did that. He let go of his hair to start rubbing at his side, making sure to also not add too much weight on top of him. “You good, baby?”
Katsuki hummed and slowly lifted his hand to put it on Izuku’s nape. “Yeah,” He whispered. “Fuck. That felt amazing.”
Izuku chuckled and nuzzled his nose into his blonde spikes. “I know right?” he said softy.
He heard Katsuki snort. “Yeah. Why have I never done that before?”
Izuku’s eyes snapped open and he froze. “What?”
“Yeah,” Katsuki answered, not noticing Izuku’s reaction to that knowledge. “’m not a virgin or something but I never did anything with my fuckin’ ass,” he chuckled. Apparently his filter goes away after he comes. “Fuck, Zu. I feel fucking amazing right now.”
Pure and raw, carnal desperation filled Izuku’s head. “Please let me fuck you, Kacchan,” he begged. “Please. I'll make you feel even better.”
Katsuki barked out a laugh. “You’re really pathetic you know that.” He turned on his back, causing his fingers to slip out and making him let out a soft whimper. “Ngh, ‘course you can.” He opened his eyes and wrapped his arms around Izuku’s neck. “Make me your good boy, Daddy.”
With that Izuku leaned down and captured his lips again, pushing his tongue in right after. He bit his lip and sucked at the muscle and relished the sounds coming from Katsuki while he pushed his boxers off.
He patted his hand on the bed to find the lube before he pulled away to sit back on his hunches. Putting some on his hand, he lathered his cock up before leaning down again and lining himself up. Those powerful arms are back around him and he looked Katsuki in the eye, a silent conversation happening between them.
As soon as he found what he saw, he snuck one arm underneath him to hold onto his shoulder before pushing in.
Fuck, he could cum right then and there ─ that’s how fucking good it felt. He focused on his breathing and not trying to bust his nut instead of the sweet sounds escaping Katsuki's mouth. The tip popped in and he groaned, grabbing Katsuki's hip and stopping his movements before he embarrassed himself.
His grip on his shoulder and hip is tight enough to bruise but he couldn’t even let up even if he wanted to. He looked up and almost came again at the sight. Katsuki's head is thrown back, his mouth dropped open with heaving breaths escaping his red, kiss swollen lips, his neck and chest bloomed in a heavy blush.
He looked back down at where they were connected and clenched his jaw, pushing further inside. He leaned down to kiss him when his hips touched his ass, bottoming out. Katsuki kissed him back just as enthusiastically, fighting back with the same inferno he always does even if his arms are shaking from arousal.
He pulled away slightly, their lips parting making an obscene sound, still connected by a string of saliva to look him in the eye before tightening his grip, Katsuki doing the same, and drew his hips back. When only his tip was inside that searing heat, he pushed back in slowly.
He did it again and again, watching Katsuki's face closely, before picking up the pace when he was sure that it wouldn’t hurt anymore.
Soon, he was ramming in his tight ass like it was his kryptonite. Maybe it was.
Katsuki is moaning obscenely underneath him ─ loud and unashamed in letting his pleasure known to everyone with ears. “Daddy!” he screamed without a care in the world, totally lost on the electricity coursing through his veins. He tried to hold onto his back, nails biting in the skin but slipping anyway from the amount of sweat running down.
Izuku groaned and buried his face in his neck, sucking at every patch of sweaty skin he could find. Sweat is running down his temple, and his curls are plastered to his forehead as he chased his orgasm. “I’m close,” he said with clenched teeth, trying to hold off. “Cum with me? Be a Good Boy for Daddy?”
Katsuki nodded his head. One of his hands left his back to grip his damp curls. “Yes.” He slurred. “wanna be good ‘or Daddy!”
“Fuck!” Izuku groaned, and thrusted harder. “C’mon, baby,” he grunted. “Cum for me.” With one more thrust against his prostate, he shot down ropes of cum in his ass just as Katsuki screamed and shook with the weight of his own orgasm, coming across both of their chests.
Izuku kept his face in his neck while they twitched from the aftershocks, his arms shaking violently from trying to hold up his weight to prevent himself from collapsing on top of Katsuki. The blonde was carding his fingers through his curls, and it made him absolutely melt.
He felt Katsuki clench around him and he hissed, digging his fingers in his hip. “Shit, Kacchan, careful.”
Katsuki groaned loudly. “Then pull out, dumbass!”
“Can't,” he answered and continued before he could retort. “You’ll feel empty and it's the worst feeling ever,” he mumbled against his collarbone.
Katsuki huffed against the side of his face. “Then just fucking lie down, ya idiot ─ you’re shaking.”
Izuku shook his head, forehead digging in his shoulder. “I'll crush you,” he said even though he was already putting more weight down because he knows that Katsuki can take it.
And just as he predicted, Katsuki said just that. “Don’t fucking underestimated, shitty Deku!”
Izuku huffed out a quiet laugh and dropped his whole body on top of him. “There. happy, baby?”
Katsuki grumbled something and Izuku laughed again, kissing a spot on his neck and relishing the shiver that went through his body.
They stayed like that for a few minutes, bashing in the afterglow of their orgasms and just being with each other. Izuku thought about how he feels closer to Katsuki than he has ever felt, considering he just saw him at his most vulnerable. He can't fight the smile forming on his face at that.
Katsuki loved the feeling of Izuku on top of him, the weight comforting him in ways he didn’t know was possible. He didn’t expect this morning to go this way, especially not after how he started it, but he can't find it in himself to bitch about it ─ he just had the best fuck of his life.
Izuku is probably still convinced that Katsuki had moved on already from him because it doesn’t matter that he can dissect a quirk in seconds, he is still the most oblivious guy he has ever met.
He opens his eyes and stares at the ceiling, still carding his fingers through his curls because he finally has the chance to do so. It's just so addicting ─ the way they wrap around his fingers and how soft they are ─ he loves it.
“Izuku,” he calls out and the man on top of him hummed in his neck. He braces himself for the words he is about to say. “I didn’t move on,” he pauses. Izuku has gone completely still, and he thinks that he isn’t even breathing but he continues because he needed to know. Not just for Izuku but also for himself. “I love you.”
Izuku wrenched his face out of his neck to stare down at him with wide watering eyes. “Kacchan− you− huh−” he stutters and it's almost fucking cute if his dick wasn’t still in his ass.
Katsuki huffs and pulls him down to kiss him. “I’ve never kissed anyone but you,” he mumbles against his lips.
Izuku pulls away to look down at him, again, and this time Katsuki gives him the chance to really process it. He can see it happening in real time ─ the gears turning in his head before the lightbulb finally turns on. He smirks when he sees it and watches as Izuku smiles so bright that he has to resist looking away. “Really?!” Izuku exclaimed, fucking elated.
Katsuki nods. “Yeah dork, I really fucking love you.” His own voice is thick with tears and hoarse from the screaming. Years of hope and loss and just a flood of emotions almost being too much that he wants to cry himself when he sees tears falling from Izuku’s eyes.
Izuku leans down to kiss him again and it is actually just teeth clanking together because they couldn’t help their stupid grins. “I love you, too, Kacchan!” Izuku said, sniffling but still grinning wildly. “I love you, too,” he sobbed and buried his face in his neck again, shoulders shaking from the wave of emotions crashing through his body.
Katsuki huffed out a laugh and shook his head, holding onto him tighter. “Dork.”
