Chapter 1: How could they know?

Chapter Text

Bakugou actually hates parties.

Like really fucking hates them. 

 

He's sitting at the bar drinking some sort of French vodka the bartender gave him, gosh, he won't even dare try to pronounce the name.

You might be wondering. Why the fuck is Bakugou here?

Well, he's there because it's Mina's birthday, and well Mina loves to "turn up" during times like these, so the least asshole-ly thing to do would be to come, right?

 

Anyways, they're playing this song by Chris Brown, it sounds good, bakugou has a very specific taste for R&B. At least that's one thing he's happy about at this party-

 

" Suki! Wassup man! " 

He knows that voice like the back of his hand, Its Eijirou. 

Kirishima seems a bit buzzed already, some hairs sticking to his forehead, due to sweat

Gosh, he looks so..wow.

He's wearing some black combat boots, with a white tanktop, some skinny black jeans, and pulling the outfit all together, he's wearing a silver chain, his long hair starting to gain its black roots back. He looks straight out of a vogue magazine.

And my god, his arms are so-

 

"Yo, you good man?"

Fuck, he zoned out. 

" I'm fine dumbass, how much have you had to drink?" Bakugou exclaims, trying to change the subject.

" Not much, just enough to feel fuzzy inside, ha. " Kirishima replys.

 

Bakugou gives him an eye-roll, and sighs.

 

"Cmon, suki let loose a little! You're always so tense. "  Kirishima says. 

"Im not tense, dipshit just tired." bakugou defends.

" Thennn, lets wake you up "

Kirishima asks the bartender to give them 2 cups of Bacardi.

 


                                                    "   Yea yea yeah they don't know about us, they don't know about it.  " 

 

The night started to get more restless. Now, Kirishima is sitting at the bar with Bakugou, one hand on his thigh rubbing back and forth, both eyes are hazy with lust, the air thick. Bakugou and Kirishima are both equally tipsy now, everything around them a blur.

Now.. Bakugou and Kirishima have always had something going on ever since UA, they've had that close connection with each other ever since, so them talking, bonding even, isn't new, but this sudden tension, is new.

..

"I love this tank of yours. " Bakugou said without thinking.

surprised by this sudden compliment,  Kirishima replies with a nervous but firm tone,

“ Thanks suki..I like…your earrings, the orange really makes your eyes pop.”

the side of Bakugou's mouth twitches at the compliment, by the way Bakugou is acting, the alcohol definitely made him let “loose” a little. 

. Kirishima is looking at Bakugou like he’s hungry. Kirishima leans Bakugou's face to the side, Bakugou and Kirishima eventually make eye contact..making him look directly at Kirishima. Kirishima leans into Bakugou's right ear, hand still on his leg.

 

“You want to come to my place..?”

 

“  How could they know? “ 

Chapter 2: The party & the after party.

Summary:

Bakugou and kirishima hunch, bakugou brings up something he wonders.

Notes:

(See the end of the chapter for notes.)

Chapter Text

Surprisingly, Bakugou, already being in a tipsy state, said yes. Plus, he had no fucking ride home anyway. And Bakugou hasn’t had fun in a fucking hot minute.

 

They arrive at Kirishima's place.

Kirishima unlocks the door.

They step inside and take one look at each other, and lips crash.

It was sloppy, messy, wet, and hard.

"I understand, your body wants it"

 

The hunger between the two was sufficient, Kirishima, placing his hand around Bakugou's neck. kissing Bakugou like he was his last meal.

“Mmm” Bakugou moans.

Bakugou, trying to keep up with Kirishima's tempo, was kissing back equally as hard.

Bakugou abruptly says;

“ Take this off.”

Kirishima looks at where Bakugou is holding onto and starts to remove his tank, showing off his tatted chest. Bakugou looked in utter awe.

 

Kirishima wanted Bakugou to return the favor.

Can this come off?”

Bakugou takes off his jacket, white shirt leaving his chest exposed, his scars stealing the spotlight of his abdomen.

Kirishima runs a finger over one of them, getting Bakugou to shiver.

God, Bakugou needs this so bad.

Kirishima grabs Bakugou by the waist and carries him to his level. Bakugou entraps him with his legs.

Their lips are still connecting with each other. Kirishima takes them up the steps.

" I know your thoughts, oh, you 'bout it, 'bout it "

Kirishima places Bakugou on the bed, taking off his own pants. Bakugou takes this as the cue to take off his.

Now, they are both fully undressed, their bodies exposed to the cold apartment air. Kirishima spreads bakugou open, watching as his length falls.

Kirishima opens his mouth to tease Bakugou near his thighs. He licks his inner left thigh, then slowly, but surely, goes to the right thigh. Licking up and down.

“Fuck, just get on with it.”

“ So impatient. Don't rush, baby.”

Bakugou shivered at the name.

“Don’t call me that..” but bakugou said it with little, to no bite.

“Okay, I won't baby." Kirishima chuckled under his breath.

Kirishima licks his fingers and slowly inserts two fingers into Bakugous entrance, going slow and steady, careful not to hurt him. Bakugou arches at the sudden pressure. He huffs,

“ fuckk, ha-”

“Kirishima fuckin get on with itttt”

bakugou whines.


" Ride with it, ride with it "

 

Kirishima is grabbing bakugou by his hair, grinding into him at a slow but hard pace, Bakugou eyes are rolling in the back of his head, moaning under kirishima. Kirishima tilts down to whisper into Bakugou's ear.

“ You like that sukii?”

Bakugou doesn’t reply with words, only a head nod.

Kirishima starts to go faster and that's when Bakugou starts to tanker a bit.

“Fuck, Fuck, fuck, fuck, FUCK-” Bakugou moans.

 

"So loud baby.." Kirishima whispers.

 

" Everybody wants you, you can have them all
but I got what you need. "

 

Kirishima stops pounding into him, and flips him on his back. And starts to ravish Bakugou, overstimulated by this sudden drastic change in position and feel, his legs start shaking. He's so overwhelmed with pleasure.

"Fuck, Fuck,-argh, rou, I think..- I think I'm gonna cum.." Bakugou exclaims.

"Then do it, its just you and me baby, only me and you. " Kirishima says.

 

Bakugou then shoots ropes of cum all over Kirishima's chin.

 

"Fuck sorry-"

Kirishima cuts Bakugou off by kissing him quick, and lazy. Kirishima breaks apart the kiss to say ;

" Don't be sorry, that was like the best sex I had in a while.


After getting cleaned up and situated, Bakugou and Kirishima end up in the kitchen,

Bakugou is raiding kirishima’s fridge, looking for something to quench his thirst.

” Rou… All you have is fucking energy drinks in here..” bakugou says with a stank face.

” Uhh, and what about it? “ kirishima says in a fake sassy tone, just wanting to get a reaction out of bakugou.

“ Well.. it’s fucking ridiculous..” bakugou says.

” Don’t know what to say man” kirishima shrugs, chuckling under his breath.

“ Well, fuck you very much. i’m going to sleep on the couch.” he slams the fridge and lays unto the couch.

”Night to you to sukii.”

Chapter Text

 

Bakugou wakes up, and for a second, doesn’t really register where he is.

Is this Rou’s house?

The memories of last night cloud his thoughts.

 

" Don't be sorry, that was like the best sex I had in a while." The memory of Kirishima talking to him after their rendezvous just hits him.

right, they hooked up..

 

He arises from the couch, searching his joggers for his phone.

What time is it?

Bakugou's heart skips a beat as he checks the time.

 

FUCK.

He shoves on his slides. He needs to leave, now.

SHIT

He forgot he didn’t even drive home; he must have been extremely buzzed because what the actual fuck was he thinking last night?

Bakugou ends up calling an Uber.  

"Turn your phone over, when it's all over"

 

As he gets into the Uber.. Bakugou has the urge to text Kirishima.

                 

Suki: Dumbshit, I just left your house, I'm going to work, see you there.

The chat log goes silent for a second until Kirishima starts to type.

Rou: yeah, just realized.. See you at work! Luv u sukii.

Bakugou smirks at the “luv u”. But then straightens his face after realising he was smirking a little too hard.

 

The whole Bakusquad was discussing random topics, as usual.

Denki and Sero were having a debate between Mina and Jirou about where is the best fast food place to eat at.

Sero exclaims, “McDonald's solos,”  he says, crossing his arms and leaning back into the lounge chair, having a cocky look on his face.

Mina and Jiro look at each other and sigh, sucking their teeth.

"I'm saying! I mean, you could never go wrong with McDonald's, McDonald's is always there for you when there's no good fast food around, you can always count on McDonald's- “

Bakugou walks into the lounge area.

Denki stops talking, and the bakusquads' attention is stuck on the presence that comes in. “ Hi fuckfaces, I'm here…Rou might be late like usu-”

Bakugou stops for a second to figure out the reason why the whole room is looking at him like he’s an intruder. Denki whispers something into Sero’s ear, still looking at Bakugou. “ What's that on Bakugou's neck?”

He slowly points to the left side of Bakugou's throat, and Bakugou himself uses his hand to block the spot.  

How the fuck was it THAT noticeable?

Bakugou slowly leaves the room and goes to the bathroom.

​Sero says, breaking the silence “ was that a hickey?”

 

Mina agrees, “ Oh for sure,”

 

“ You think Bakugou is hooking up with somebody..?” Sero says

Mina agrees in a confident tone, “ Oh, for sure.”


You know better than that.

I come around when you least expect me.

I'm sitting at the bar when your glass is empty.

Bakugou is in the bathroom, he touches the red and purple spot on his neck. He's so in disbelief. Oh he’s going to gnaw at Kirishima's ​face in anger when he comes to work. See, he knew that kirishima was going to leave a mark, but he didn't know it would be bold enough that fried-brain was actually able to notice it, For denki to be able to notice anything it has to quite literally be in plain sight.

Bakugou ​tries to use some cold water to dilute the hickey. It helped somewhat, but didn't help drastically. 

 Ohhh kirishima is soo fucking done for.

 


 

Finally, Kirishima arrives at work. An hour. late, he’s notorious for his late arrivals.

“ Ahh, kirishima. You finally joined us.” Aizawa said sarcastically. 

“ Yeah, I got lost in the sauce a bit ha.” Kirishima nervously says, he takes his seat and purposely sits beside Bakugou.

“ Yea you got really. "lost in the sauce" Stupid fucking idiot, you left a bit of a mark yesterday, crazy.” he whispers. “ Yea, last night was crazy.” Kirishima says, smirking. Bakugo's ears slowly start to have a pinch of red on the top after kirishima said that.

 Aizawa starts to lecture the team. 

“ You guys have a lot of training to do, you guys have been on this team for 1 month, and I'm already seeing slack off. Just because you're on this team doesn’t mean you guys aren't in danger of being off it. 

“Our skills are like the tools on the rig; if we don't use and maintain them, they tarnish. Meaning that i need to see consistency from this team, Sure you can have your parties, and you can have "fun". But you still need to realize that we are this town's Heros. And they are counting on us.”

 

Notes:

Sooo firefighter AU! How are we feelingggg?

Chapter 4: Beware , Beware , Beware.

Summary:

kirishima wants more. Bakugou doesn’t need more.

Notes:

Hey everybody! i apologize for the long wait! Life chews you up and spits you back out. This one is going to be a teensy bit harsh! every good fic needs to be a little bit angsty :))

By the way, in the middle of this fic there will be a flashback! So i’m just clearing up the air before you guys get confused! 😵‍💫

(See the end of the chapter for more notes.)

Chapter Text

“ Looking at the stars like they finna’ talk back

Looking at my phone like he finna call back 

 

 

Kirishima arises from his bed. The feeling of good sleep never fails to ease him. He stretches his arm out and yawns, his muscles releasing tension.

 

Today is a weekend so that means it’s a day off, aka.. chill at bakugous house and probably makeout day.

 

Kirishima can admit, he absolutely loves going to bakugous to talk, and other stuff. But he hates how he has to keep it low.

 

Sometimes, just. sometimes kirishima wishes that he can be able to kiss bakugou after a good save, or give him a peck when he makes a good point during meetings, affection

 

But bakugou has explicitly said before  he wants nothing more than just “this”.

 


as they were in the middle of making out, bakugou establishes something.

 

bakugou’s  head moves away from kirishima's lips for just a minute. 

 

“ Rou..”

 

“ Hm?” kirishima looks at him with lust still in his eyes.

 

“ I don’t want you to get the wrong idea, we can’t be anything more than “this”.

 

kirishima connected the dots as to what bakugou meant by “ this”  he understood. Bakugou doesn’t want anything personal… easy enough.. right?

 

-

Kirishima grabs his phone from his side counter  and goes to bakugous contact.

 

Rou: suki, you free? 

 

…. 

 

Sukii: Yes.?

 

Rou: i wanna come over :)

 

sukii: Sure. But bring some food over, nothing in my fridge looks good.

 

Rou: of course sukii :)

 

-

“ But last night I feel like probably ended all that “

 

Kirishima arrives at bakugou’s house, the drive there was pretty chill, he bought bakugou’s favorite caribbean food, extra spice just how he likes. 

 

Kirishima does three little knocks with a familiar beat, and patiently waits for bakugou to answer the door.

 

Bakugou answers the door wearing a pretty cool outfit, to kirishima literally anything that bakugou wears is cool. 

 

He’s literally just wearing a white shirt with some light washed jeans. Nothing flashy. 

 

“ You gonna come in red?”

 


 

 

They end up drinking just a little bit of wine, to them alcohol helps loosen their mood and nerves. 

 

Their sitting on the couch, sitting beside each other watching a youtuber playing some horror game. Until Kirishima says something.

 

“ What are we?”

 

Bakugou’s remote is in his hand, he pauses the tv, and turns his head to look at kirishima. 

 

“ Like..what do you mean?”

 

 

“ Don’t play coy with me katsuki.”

 

Bakugou could sense the sternness in Kirishima's voice. Kirishima was serious. 

 

“ Well, i don’t know what the fuck do you mean by we.”

 

“ I mean what are we. Are we friends that just fuck?, are we buddys that just so happen to leave hickeys on each other from time to time?” kirishima says.

 

“ Then another one tryna take it all back “

“ Saying "Fuck you," "I miss you," or "I hate you so much"

 

 

“ so.. just because you left a hickey on me once. You think that we could be something more.. kirishima you do remember what I told you right?

 

“ Fuck, of course I remember. bakugou. it’s just hard to act like we’re nothing when we give each other that look. And the way when you were in my bed whispering things into my ear that you wanted me to do to you..” 

 

he paused before he started talking again. 

“ it’s hard to be “ just friends “ after that shit bakugou.” 

 

“ Ur so fucking sensitive kirishima. it’s annoying”

 

kirishima felt his words. It lingered. It pierced through him like a poisoned arrow. 

 

“ IM. sensitive? Bakugou your so fucking full of yourself. You claim to be a “strong guy” but in reality your a pussy who can’t admit how he feels. Youv’e been like this since highschool. Grow up.” 

 

kirishima said it with bite.  he wanted it to hurt bakugou. As fucked up as that sounds.

 

But bakugou didn’t feel hurt, instead he took it as a competition. Typical, fucking, bakugou.

 

“ Oh yea? That’s how you feel? What about the fact that little kirishima still needed his mom to walk him to school. You were so scared that some stupid bully was gonna come “beat” you up. You call me a pussy? You’ve been one since middle school. 

 

by now their up off the couch, their looking at eachother face to face.

 

Kirishima gave bakugou a glare that could pierce through obsidian. Sharp.

 

“ I’m done, I don’t want to just be a piece of meat to you. 

 

“ Ooh, I was so mad, I should've seen this coming right from the start

You should beware, beware, beware of a man with a broken heart’ “

Chapter Text

Kirishima left bakugou place and went inside his car to process the events at the house. 

Kirishimas hands were shaky from adrenaline,. The things he said goes through his head. 

 

“ You claim to be a “strong guy” but in reality your a pussy who can’t admit how he feels. “

 

he rubs his hands over his face and sighs. He plants his forehead on the middle of the steering wheel.

 

What was Kirishima even doing? He got on Bakugou for no reason. He felt horrible. He felt shitty.

Kirishima was tipsy and honestly he just wanted to go home and literally scream into a pillow and curse himself to death.

 

Another memory hits him. 

 

“You’ve been one since middle school”

 

ouch, his heart hurts. He imagines the look on bakugou’s face after saying it. It seemed like it  was pure anger..It was past anger. It was rage. Surely bakugou didn’t mean what he said right? 

 


 

 

Bakugou was watching kirishima  shut the door behind him. 

 

The slam of the door causing him to flinch.

 

 Maybe kirishima was right. He was scared. He was scared of the way people would perceive him.

 

Bakugou hasn’t become openly gay, I mean he didn’t even realize he was gay until he watched a show about two hockey players that hunch 3 times every episode. We don’t talk about that.

 

Bakugou felt bad for what he said, sure.

But he shouldn't be forced to become so open if he isn’t ready. It’s not fair that Kirishima wants him to just be “ready”. That's not bakugou’s tempo.

 

 

Bakugou realizes he’s still on the couch. It’s fucking 3:30am , they stayed up that late..? 

Bakugou gets up reluctantly and goes to his room. 

 

He flops onto the bed. And covered himself up with his blanket. He’s doomscrolling on his phone until he sees kiri’s contact

 

i’m gonna text him..

 

 

Suki:i’m sor| 

 

Bakugou backspaces the message , stopping himself before fully typing that.

 

Sukii: You're a dick

 

bakugou deletes that. 

 

Sukii: Rou, I'm just not ready yet. 

 

Bakugou sends the message. 

 

Kirishima reads it.

 

 

 Rou: I understand . I rushed you,…  fuck, i said some hurtful shit to you suki

 Rou: I understand if you don’t wanna speak to me again. 

 

sukii: we were both tipsy and just being stupid. 

 

Rou: yea but that isn’t an excuse, genuinely man.. I fucked up. I’m sorry.

 

Sukii: yea, yea, it’s fine. Just don’t get all sappy and shit.

sukii: just be patient. That’s all..

 

-

 Monday, 9:30 am 

 

Bakugou gets up from bed, he does not want to go to work today. 

But if he calls out “sick” , Aizawa is going to give him an hour lecture talking about how japan is counting on us ‘blah blah blah.’ typical aizawa bullshit.

 

Bakugou goes into his closet and grabs his uniform. It consists of some wide leg cargos, a black shirt with his station’s symbol on it that he tucks in. with some combat boots. Simple, but tactical. 

After he’s done he sprays some shitty cologne just to feel something.

 

-

The drive to work was like any typical work day. he most likely today would have to  save a cat from a tree, probably help an old lady not set her house on fire. Which surprisingly happens too often.. 

 

He gets to the station and of course the rest of the idiots are on the couch discussing bullshit, it’s honestly therapeutic, even though the job they do can be hard sometimes. They make it bearable. 

 

Bakugou sits down near the rest of the squad, their sitting at a circle table and theres chairs around. Mina and Kaminari are rating artists. For some odd reason they love to argue. But to bakugou it’s free entertainment.

 

“ So you're telling me you're picking drake.. over Kendrick Lamar? You're actually insane.” Mina says.

 kaminari replies  “Drake defeats any artist you can think of.” he crossed his  arms and leans back. 

 

-

Kiri eventually comes to work, but he doesn’t really say Hi or greet Bakugou..

maybe he’s still blaming himself? Maybe he’s just tired? 

 

He’s at his desk, and kirishima’s is right next to him, he peeks from the side wall and whispers  to kirishima 

 

“Rou? what is stuck up your ass today?”

 

No reply. 

 

“ Rou. Is it about yesterday..?”

 

a pause.

 

“ Did you mean what you said?” Kirishima says quietly.

 

“ About what?”

 

“ Let’s go somewhere more private..” kiri whispers 

 


 

They end up going into an empty storage closet. It’s not to big, but not to small.

 

“ So.. what did you want to talk about.?”

 

Yesterday.”

ah, so it was about yesterday

“What you said hurt me a bit, I understand I fucked up. I attacked you out of nowhere.. whenever i get alcohol in my system I act stupid…”

 

Bakugou chuckled at the last comment.

 

“ It’s just middle school was really hard for me. And you saying that made me feel shitty.”

“Fuck, i’m sorry rou, I wasn’t thinking.. my anger blinded me.” bakugou apologizes. which is very rare..

” 

Yea..but y’know some of the shit you said hurt me.  but Honestly it’s fine.. I just don’t want one drunk argument to ruin our.. “friendship”.  “

 

“ Me either..”

 


 

Bakugou eyes trail down Kirishima's chest..

 

 

“ Eyes up here blondie..”

 

“ fuck you.” 

 

Kirishima slowly walks towards Bakugou, hands behind his back, with a flirty smirk on his face.

 

“ What are you looking at..”

“ you.”

 

Kirishima, towering over bakugou, lowers his head down to kiss bakugou’s neck. Earning a tiny moan from him.

 

“ Ah, ah, more..”

 

and kirishima delivered.  

 

while he’s doing that he slowly lowers down his hands around bakugou’s waist, grinding bakugou against him.

 

Bakugou closes his eyes, giving into the pleasure.

 

“You look so pretty like this suki.”

Kirishima knows that praise is Bakugou’s weakness.

 

Bakugou grabs kirishima’s face and brings

it to his own face. 

 

bakugou kisses kirishima slowly. Just wanting to savor the moment, until realization hits.

He quite literally forgot he’s at work, fuck.

 

The sound of lips parting aired out in the room.

“ Hm? Why did you stop suki?”

“ We’re at fucking work dumbass.”

“Ughh, work can wait!” kirishima exclaims.

Kirishima lifts bakugou up unto the wall and makes eye contact with him.

 

Maybe work can wait.
