Chapter Text
Not only did becoming third years at UA feel unreal, it was honestly a goddamn miracle considering all the shit their class had been through.
Especially for Katsuki Bakugo.
He'd not only been targeted specifically by villains MULTIPLE TIMES, but he fucking FOUGHT IN A WAR and DIED. His little curtain call and coming back to life act had drawn a horrible amount of unwanted attention and doting from classmates when it was all over, making the first bit of their second year absolute hell. Nevermind the fact he kicked absolute ass and defeated All for One on his own, earning even more constant fanfare and hindrance during the school day.
To make matters worse, he had a useless fucking arm to rehabilitate that year. It still wasn’t fully back to normal yet, but at least he can move the stupid thing now. With that in mind and the fact that his heart was also doing better, Katsuki was actually pretty ecstatic about starting his final year at UA.
Not only will he be able to participate in training again finally, he's now one step closer to his over all dream: Becoming the number one hero.
The only problem? He's gotta actually make it through this year, and so far there hasn't been any giant super villains, no threats to the school or anyone jumping out of the woodwork to kidnap him, no, none of the crap he's used to.
Just normal ass school shit.
Which apparently involves another school festival where this year class 3A has decided to do a play, and you have to participate or take a big fat zero as a chunk of your final grade.
Katsuki was livid at first, not wanting to prance around in some stupid get up, pretending and acting like someone he’s not. But when he skimmed through the list of roles to be played, he quickly keyed in on one he could manage without wanting to take a swan dive off the roof of the building.
“I wanna be the Barbarian King!” Katsuki demanded, pointing at the paper on the desk where Mina and Hagakure sat cheerfully.
They somehow got dibs on making the playwright, so it was their story they’d be acting out and their call for auditions.
Mina smirked and offered a copy of the play forwards, wiggling her brows at him, “Ya sure, Blasty? Have you read the script? I dunno if you could handle the ki-“
“HAH?” Katsuki barked, swatting it from her hand, “Course I can handle it!! I’m perfect for this role!!”
“He definitely didn’t read it.” Hagakure snickered.
“I don’t have to read it to know I’d be the fucking best at it.” Katsuki huffed, crossing his arms and glaring down at them, “Barbarians are warriors and I may as well be a king already with how many first year extras worship the ground I step on. If I’ve gotta take part in this stupid play I want that role.”
“Okay, just don’t come crying to me when you read your lines.” Mina said with a smile Katsuki did not trust whatsoever.
He sneered anyways and snatched the copy of the play from her hands, “I won’t.”
“Oh heck, there’s a dragon, Todoroki!” Kirishima said nearby, smiling brightly as he looked through a list he’d picked up, “With your fire you’d be perfect for that role!”
“Todoroki is going to be the ice prince!” Hagakure amended before Todoroki could respond, “But you could be the dragon, Kirishima! Your hardening would make the red body paint look like actual scales~!”
“Oooo, yes, yes, yes!!” Mina chimed, agreeing with her excitedly as they high-fived.
“Oh, I dunno, think I could pull off a scary dragon?” Kirishima asked sheepishly, rubbing the back of his neck while showing off those sharp teeth of his.
Mineta scoffed then and pointed at said teeth, “Of course you’d be the dragon, Kirishima. You practically have fangs.”
“Oh, I guess you’re right!” The red head chimed excitedly, hardening his fists and smashing them together, “Alright! I’ll be the dragon, guys!!”
“Woo!!” Mina and Hagakure cheered.
Katsuki rolled his eyes at their excitement, also picking up on how Uraraka was already practicing lines for her witch character and Izuku was in the corner playing with props for the soldier. They were to choose roles today and read through everything tonight, then tomorrow would begin rehearsal.
With that in mind, Katsuki made his way back to the dorms to get his bath so that he could hide out in his room and read his lines, because if there was one thing Katsuki Bakugo was good at- it was everything.
He prided himself on giving his all in every aspect of his life, from strength training, to honing his quirk, to maintaining a healthy lifestyle. His mother taught him how to cook, and he didn't consider himself a prodigy until his meals rivaled that of a five star chef. She signed him up for music lessons, and he mastered the drums in a span of a couple months. His father took him hiking and Katsuki learned to pitch the tent and find his way around by the mere position of the sun in the sky.
He even dedicated extra time into his studies despite knowing the material like the back of his hand already. So of course he was about to take on this challenge of being the best fucking Barbarian King UA has ever seen. Especially when Mina had the audacity to fucking doubt him. HIM. Katsuki fucking Bakugo.
There was no way they’d written something he couldn’t handle. Fight scenes? Easy. He was ambidextrous now, so he could even wield two weapons or just attack with his bare hands if they want. Remembering lines? Please, he’s top of the class for a reason. Katsuki can remember anything. Kissing the Dragon Monarch during the big finale where they end the war with a treaty of marriage? Katsuki could do that.
He could kiss the..
Wait.
“WHAT??”
~
The theater room was full of mindless chatter and over excited students when Katsuki shoved the door open the next evening. He stomped in with a scowl and marched right up to the stage, leaping up there where Mina was doting on Iida’s armor and rambling about how he has to charge in with vigor.
“Raccoon Eyes!!” Katsuki interrupted, holding up the script on the final page, “Mind explaining what in the actual fuck this is about?”
“The ending?” Mina chirped innocently, smile not meeting her eyes as she teased him so blatantly, “Oh, it’s nothing. Just that scene I tried to warn you about, but you said you could handle it, right Blasty?”
“Yeah, ya said you’re perfect for the role.” Hagakure added, making Katsuki nearly jump out of his skin as he hadn’t noticed her there without the gloves.
“First off, why in the shit did you think it was a good idea to make this a romance??” Katsuki barked, “And secondly, why are you naked??”
“I was changing, don’t look!” Hagakure huffed, and Katsuki could tell without having to see that she placed her hands on her hips. Just like his fucking mother.
“Well, look at the bright side, Kirishima is the one you’ll be kissing!” Mina amended as she wiggled her eyebrows, “Besides, it’s just a peck on the lips! It won’t kill ya.”
“Like hell it won’t!” Katsuki growled, clenching the script in his fist, “This is stupid, change the ending!! The Barbarians wouldn’t give into a peace treaty so easily, we should just kill the dragons!!”
“Kacchan, the theme of the festival is peace and new beginnings- eep!“ Izuku started to explain in his annoying nerd way of his, earning a glare that shut him up and made him yelp in the process.
“I don’t care what it’s about, this is ridiculous!!” Katsuki barked, “Change the script or give me a new role!”
“Bakugo, everyone has already chosen their respective characters and began memorizing their lines.” Iida interjected, “It would be very rude and unproductive to backtrack and have you swap roles with someone now.”
“I didn’t know class 3A was so chicken when it came to romance!” Monoma taunted as he and Kendo sauntered by holding props, “The Great Explosion Murder God Dynamight done in by a little kiss, who would have thou-“
Kendo quickly chopped the back of his neck with her hand, effectively shutting him up, “Erg, sorry about him. We’re leaving now, just had to grab a few things.”
Katsuki was gritting his teeth, seething already and making sparks involuntarily fly in his fist before Mina made it worse, “Ya know, he’s got a point, Blasty~ You’re not gonna chicken out cuz of this one scene, are you?”
“Hah?? Who do you think I am??” Katsuki huffed, clenching his jaw and puffing out his chest, “Fine, you wanna see a kiss? I’ll do it, I’m not chicken!! And our class is gonna blow them away, we’ll put on the best damn play those B list idiots have ever seen, goddamnit!!”
“Woo, now that’s the spirit!” Hagakure beamed.
And just like that, rehearsal began. To get into the mood, Mina had everyone go ahead and put on their costumes save for the makeup and extra accessories. ‘Just the clothes part will do for now,’ she’d said. The play itself wasn’t terribly long, a quick albeit surprisingly well put together conundrum of multiple fantasy elements involving kingdoms and villages all at constant war and disarray.
There were meetings between certain characters and fight scenes here and there, and finally the two most powerful of the realm, according to the script, were to end the war with a marriage between the Barbarian clan and the Dragon Tribe, overseen and blessed by the Ice Prince. Katsuki handled his lines with finesse and admittedly had fun swinging around the plastic sword, wishing it were real as he fought off his classmates with pretend swings that may or may not have been a little tad aggressive.
But then it came time for the final scene, and Katsuki met Kirishima’s gaze from across the stage and suddenly it was like his heart decided it was being obliterated by Shigaraki again. It was beating hard in his chest and he felt his face flush, but he wasn’t sure as to why. He was already a bit sweaty from all the moving around despite his costume not even having a shirt, just a fur lined cloak over his shoulders and pants and boots.
Kirishima’s face was also reddening slightly as they spoke their lines and listened to ‘The Ice Prince’ announce the treaty and that they would seal the promise of peace to the realm with their unification. Katsuki gulped as Todoroki finished his little speech and motioned for the two to kiss, and Kirishima offered him a quick, sheepish grin before leaning in, ghosting his lips against Katsuki’s.
“This okay..?” Kirishima whispered, voice surprisingly raspy.
Katsuki wasn’t sure why the fuck he was so nervous, but his breath hitched as he nodded and mentally said screw it, pressing his lips forward a fraction so they’d connect with his best friend’s.
He pulled back quickly, too stunned and flustered by how his body was buzzing with adrenaline to know what to do with himself.
Mina cracked up then, snapping him out of his stupor in record time as he growled and fixed her with a look that could kill.
“What the hell is so funny, Pinky??” Katsuki barked.
“You guys looked terrified of each other!” Hagakure answered for her.
“Yeah, ya looked constipated, dude.” Sero snickered, walking over and patting Katsuki’s shoulder, “I get that you’re allergic to romance and affection, but ya gotta not look at Kirishima like he’s gonna eat you.”
“Wha- FUCK YOU, I WASN’T SCARED!!” Katsuki barked, slapping his hand off, “If anything, Shitty Hair was the one who hesitated!!”
“Hey, I just wanted to make sure I had consent..!” Kirishima defended, holding up his hands in mock surrender.
“It’s a play, it’s not a real kiss.” Mina drawled before smirking at them, “Okay, now try again and actually pretend you like each other.”
Katsuki’s eyes widened as he directed his attention back to her, “Hah?? Why?? No one else had to redo their scenes!”
“The kiss is the most important part, it’s the grand finale and what brings peace to the realm!” Hagakure huffed dramatically, “You guys have got to get it right or the whole play will be in shambles!”
“Grr!!” Katsuki gritted his teeth, turning back to Kirishima, “Fine!! Come at me, Shitty Hair!!”
“Bakugo, it’s not a fight!!” Sero cried, falling over laughing with tears.
“Bakugo, just look at him the way you do in class sometimes.” Todoroki deadpanned, making Katsuki’s face turn a very, very bright red. Because.. what??
“Hah??” Katsuki barked, eyeing Todoroki accusingly and grabbing the front of his ridiculous prince costume, “The hell are you on about, IcyHot?? I don’t look at him during class..!!”
“Okay everyone, settle down!” Iida chimed, “Rehearsal time is up, we need to get dressed and put everything away before heading back to the dorms! Single file line on the way out, please!”
“Same time tomorrow, guys!!” Mina tacked on before patting Katsuki’s shoulder, “And you two, don’t worry. We’ve got a week of this before the play, surely you’ll learn how to pucker up by then.”
Forgoing whatever anger he had for Todoroki, Katsuki scoffed and shoved Mina off and stomped away to change. He couldn’t believe this shit, he was not about to lose to a fucking kiss scene in a goddamn play. He wasn’t scared, and he sure as shit wasn’t going to mess it up and have to ‘redo’ the scene more times than he already had to.
As soon as everyone finished up, Kirishima caught up to Katsuki on their walk back to the dorms and bumped his shoulder against his, “Hey, man. Sorry about-“
“You’re coming to my room when we get back.” Katsuki said, cutting him off.
Kirishima blinked dumbly at him then nodded, “Uh, sure, okay!”
The walk to his room was brisk, shoving between other classmates and stomping up the stairs when deciding waiting for the elevator wasn’t worth it. Kirishima kept up, trailing along behind him like a concerned puppy until they made it to his door and stepped in. Katsuki shut and locked it behind him, and as soon as he turned around Kirishima held up his hand to stop him from speaking.
“Before you even start, I know.” He said solemnly, “I dunno why I was so nervous, I promise I’ll do better and-“
“Shitty Hair!” Katsuki huffed, making him meet his gaze with that stupid sad ‘please don’t be disappointed in me’ look, “Shut up, okay? I’m not mad at you.”
“Oh.” Kirishima said, the tension visibly deflating from his shoulders as a wide grin spread across his face, “Well then, what’s up, man?”
“We’re gonna practice.” Katsuki told him, crossing his arms and narrowing his eyes at him with determination.
“Practice.. what?” Kirishima asked, as if completely oblivious. Ugh.
Katsuki groaned and nodded towards the bed, prompting him to sit before joining him by his side and facing him with his leg pulled up on the bed between them, “The fucking kiss scene. I don’t want those losers making fun of me again, so come on. Let’s do it.”
Katsuki had never seen Kirishima’s face turn so red before in his life, the tint on his cheeks practically matching his hair as his sharp toothed friend began to stutter, “Wh- What?? You mean, you wanna practice, k-kissing?? With me??”
“Well, duh! Who else, Hair for Brains?!” Katsuki huffed, fixing him with a glare, “We’re the idiots that have to do that dumb scene, and I won’t be made a fool a second time. We’re gonna master this and prove to them that I can handle a stupid kiss just fine!!”
“Oh, right! Okay, man!!” Kirishima agreed, still seeming nervous but something akin to understanding flashing across his features, “Okay, so how do ya wanna do this? We gonna read off Todoroki’s line before or..?”
“Nah, I’ve got the acting and lines down, I just haven’t..” Katsuki tailed off, feeling that stupid embarrassed, timid bullshit stirring in his chest again, “Ugh, I’ve never kissed anyone before, okay? Until, earlier, with you.. I need to practice so it’s not new and weird and I can be ready for it when in front of the others.”
“Ah, yeah! That makes sense!” Kirishima agreed, nodding along despite still looking like he was on the verge of passing out or having a heart attack, “I’ve never kissed anyone before either, ya know.. being busy with the war and all..”
Katsuki scoffed and rolled his eyes, “Yeah, no shit. Okay, just.. Let’s do it, now.”
Kirishima nodded once and met his gaze for a brief moment before dropping those matching crimson eyes of his to Katsuki’s lips. Katsuki felt his traitorous heart doing flips again and closed his eyes, trying to will himself to calm down as they both leaned towards one another.
As soon as their lips brushed, Katsuki could feel Kirishima gasp against him slightly and for some reason it made his own breath hitch again like last time. Fuck, why was this so hard?? It was a kiss, it should be easy. And Kirishima is his best friend, Katsuki may not handle physical touch or affection from other people, but he can at least tolerate it when it comes to Kirishima.
Finally with a bit more confidence, Katsuki pressed his lips firmly against Kirishima’s before pulling back, “There, see? Easy fucking peasy.”
Kirishima looked stunned and nodded his head, “Uh, y-yeah, I dunno why but I’m still feeling kinda.. um..”
Katsuki hated that he agreed, his whole body practically shaking with nerves, “Ugh, fuck! Let’s just keep trying, surely if we do this enough we’ll get used to it and it’ll be as easy as breathing.”
“Right.” Kirishima nodded vigorously, “Um, sh-should we like, try to kiss for longer? Or something?”
Katsuki felt his face heat at that but agreed quickly, “Yeah, that makes sense..”
Kirishima scooted closer then, trying to face him a bit more instead of twisting awkwardly. Katsuki swallowed his nerves again and leaned in, eyes half lidded as he met Kirishima half way. He didn’t let them flutter shut until their lips touched again, proud with himself for how much easier they’d connected that time.
Progress!!
Now just to get used to the feeling. It was weird, Kirishima’s lips were oddly soft against his own. He shifted a bit and in turn it made their lips slide against one another’s, making Kirishima stiffen for a moment before his mouth began moving deliberately against Katsuki’s.
Katsuki wasn’t sure what was happening or why, but his heart was suddenly racing again and he pulled away quickly, “Uh- I think, I think it’s getting easier now.”
Kirishima blinked his eyes open and agreed, “Yeah, I think so too. You uh, wanna keep going, or..?”
Katsuki nodded, shifting fully back on the bed with his legs crossed as he faced him, “Yeah, I wanna be good at this so they don’t say anything stupid tomorrow. C’mon.”
Kirishima scooted fully on the bed as well, mirroring his position before they leaned in to kiss once again. Katsuki was a bit more confident that time, closing his eyes just as their lips met and pressing them firmly into Kirishima’s soft ones that were- oh shit, they were a little wet. Had he licked them?
And damn, why’s he moving again? Fuck, is this how kissing worked? Katsuki’s mind was reeling as he tentatively started parting his lips as well, moving them with Kirishima’s lead and well, actually kissing. He focused on his bottom lip as Kirishima did the same on his top, the feeling making his skin tingle and his body start to warm.
He let out a soft sigh sort of involuntary as he started to relax into the feeling, earning a little ‘mmm’ sound from his friend. Katsuki didn’t know why the little groan or whatever the fuck it was made arousal stir in his gut, but he quickly ignored it and focused on the task at hand. He had to master this and become good at kissing so he wouldn’t get laughed at again.
This time though, it was Kirishima that pulled back first, and he was panting softly and met Katsuki’s gaze with pupils blown wide and a look in his eye that made Katsuki’s cock twitch in his pants. Fuck, what the fuck? He could not get turned on right now. Sure he liked Kirishima and thought he was attractive, but Katsuki was not in the market for a romantic relationship right now- or ever maybe.
He was going to become the number one hero, not date and fall in love and all that other useless crap.
“Sorry,” Kirishima said, snapping his attention back to him, “I uh, I think that’s enough for me for today, if that’s okay with you.”
Katsuki nodded quickly, strategically placing his hands in his lap as he leaned back, “Yeah, okay.”
“Um, well, I’ll see you tomorrow, man.” Kirishima said with strained nonchalance, offering a weak smile as he shuffled out of bed and headed for the door. He smiled more genuinely then as he peered back and waved without turning fully around, “Bye!”
Katsuki raised his hand to wave him off before watching him disappear into the hall, leaving him alone with a half hard cock and a lot of conflicting feelings.
~
The next day dragged by, and Katsuki couldn’t get what Todoroki had said out of his head during class. Sure enough, he found his gaze drifting towards Kirishima a couple different times and fuck if that wasn’t annoying as shit. Was IcyHot trying to insinuate Katsuki did that often? And if so, why did he? Why was it enough that it was noticeable??
And damnit, it’s not his fault Kirishima draws his attention. Bright ass red hair and a smile like sunshine, who wouldn’t be drawn to that? His presence demanded attention, the idiot may as well have a neon sign lit up above him screaming ‘LOOK AT ME I’M HANDSOME AND SWEET AND PERFECT.’
Ugh, it wasn’t like Katsuki had a fucking crush on him or something.
Besides looking at his friend, Katsuki’s eyes also kept darting to the clock. He was ready to get to their rehearsal. He wanted to show those assholes that he could do the kiss scene just fine. Now that he and Kirishima had kissed a few times, there was no way it would go as disastrously as it had the first time.
Only apparently it could, because after finally getting the school day over with then running to the theater room and doing all the scenes and lines flawlessly- Katsuki was nervous again. It was time for the kiss, Todoroki had just finished his dribble about peace and whatnot, and Kirishima was bright red again and Katsuki’s heart was doing backflips and breakdances and all sorts of dumb shit besides just beating like a normal goddamn heart.
Still, he swallowed his nerves and met Kirishima half way, trying to hurry through the motions with everyone’s eyes on them and accidentally slammed into him too hard. Their closed lips kept their teeth from actually clanging together, but it still felt like getting punched in the mouth as they both winced and pulled back, covering their mouths with a groan.
“Shit, sorry, that was my bad..!” Kirishima said as laughter erupted around them.
Katsuki gritted his teeth as Mina cracked up nearby and yelled at them, “Oh my god, that was worse than yesterday!!”
“You guys even know how to kiss?” Sero teased.
Katsuki yelled angrily and made explosions with both hands, “Of course we know how!! This is just stupid and you’re all fucking staring!!”
“The whole school will be watching for the actual play.” Todoroki deadpanned, making Katsuki’s face heat as he groaned and clenched his fists.
“Alright, let’s wrap it up!” Iida chimed, “Good work everyone!”
“Pft, everyone but those two.” Jiro snickered, making Katsuki fucking growl in anger as he stomped off to the changing room.
He couldn’t believe this, failing AGAIN!! Ugh, he was not going to let this beat him, damnit!!
Katsuki Bakugo was the best at every damn thing, and he’d be the best goddamn kisser in the whole fucking world by the end of this!!
“Shitty Hair!!” Katsuki huffed, marching over to the red head once they were back in their school uniforms, “Go ahead and get your bath when we get back then meet me in my room, you’re not fucking leaving until we get the hang of this shit.”
Kirishima’s cheeks dusted a faint pink as he nodded, “Okay.”
~
Once they’d gotten back to the dorms and had their baths, Katsuki was waiting in his bed wearing sweatpants and no shirt, deciding to try and get into character for the kiss. Surely that’s what they were doing wrong- it was a play, after all. They were acting. He was the esteemed Barbarian King, and Kirishima was the Dragon Monarch, and they were kissing to seal a deal of peace between the realms.
He needed to channel all of that strength and devotion and urgency into their scene, really focus on playing the part rather than his stupid fucking nerves and inexperience.
Kirishima knocked lightly on his door before peeking inside moments after Katsuki had arrived, “Hey, man.”
“C’mon, we ain’t got all night.” Katsuki huffed, motioning him to hurry up.
Kirishima shut the door behind him, his hair still damp and lacking the spiked up appearance he normally sported now that all the hair gel had been washed out. He was in shorts and a t shirt, and Katsuki couldn’t help but to think maybe them being more comfortable would also help them relax and kiss more easily.
“Okay, I did some thinking and I realized we need to just stay focused on our roles is the problem.” Katsuki said as his friend crawled into bed with him, “Remain in character and remember this is our duty. It’s for the sake of the- why are you laughing??”
“Sorry.” Kirishima said with another soft giggle, clearly struggling to not laugh outright, “You said duty, dude.”
Katsuki tried his best not to smile as he shook his head and scoffed, “Oh my fucking- Kirishima, get your head out of your ass and focus, you idiot. We’re not little kids.”
“Sorry, sorry.” Kirishima reiterated, smiling happily as he got situated in front of him, “Alright, carry on.”
Katsuki rolled his eyes at his antics and met his gaze again, “Okay, just fucking remember who you’re playing, okay? We’re the leaders of our people. Us getting married means peace for the realm, no more bloodshed, no more fallen companions. It’s serious business, and this kiss will prove our union.”
“Right, right.” Kirishima agreed, seeming to get serious, “Okay, maybe it would help if we acted with the rest of our body as well?”
“What do you mean?” Katsuki asked, arching a brow at him.
“Well, we’ve only met before in battle.” Kirishima explained, “I think just leaning in and touching lips would be kinda out of character for two men who’ve fought and shed blood together, I think I’d grab your face or you’d reach out to me first, some kind of touch before actually kissing.”
Katsuki thought it through and nodded in agreement, “Yeah, yeah that makes sense.” He took a deep breath then and scooted closer, letting their knees touch where their legs were crossed in front of each other, “Okay, let’s try it.”
They held each other’s gaze for a moment as Katsuki thought about what the Barbarian would to, deciding to go for the Dragon’s chin as if to challenge him to kiss first. Kirishima leaned into the touch, his eyes falling half lidded as he brought both hands up and cupped Katsuki’s cheeks gently, staring at him with something that made his heart beat hard rather than just fast.
It felt like he was looking into his soul, or seeing something he wanted to claim as his own.
Katsuki took a few measured breaths before meeting him half way, his eyes fluttering shut as they pulled each other into the kiss. Katsuki didn’t actually mean to part his lips this time, but it just felt so natural and Kirishima seemed to meet him with the same sentiment. It was easygoing like the last time they’d practiced, Katsuki focusing on Kirishima’s soft bottom lip and accidentally sucking it just a bit and the red head in turn doing the same with his.
Katsuki groaned softly when tasting a hint of strawberry from his friend and slid his hand from his chin and around to the back of his neck, pulling him closer. Kirishima groaned and reciprocated the extra movement by parting his lips more and suddenly Katsuki was completely sharing every breath with his friend. He started feeling restless and wanted.. something. Felt like he needed more somehow, like this was just-
Oh, fuck, that’s it.
Kirishima’s tongue licked across his bottom lip and Katsuki released a sound he decided didn’t come from him as he eagerly did the same, their tongues meeting in the middle of the kiss and turning it wet and messy. Suddenly Kirishima’s hold on him went from gentle to firm, one hand slipping to the back of his head and the other falling down to grab at his shoulder.
Katsuki’s heart was back to thudding wildly in his chest again as he got lost in the sensations, exploring each other’s mouthes with their tongues and pushing and pulling against one another. Arousal was pooling heavily in his gut and he knew he needed to calm down before he embarrassed himself by popping a boner in front of his friend, but Kirishima was making little grunts and groans against him that had his mind struggling for control as his body just ached for more.
“Hmm, Bakugo..” Kirishima practically growled into his mouth, making Katsuki let out another whimper that fuck you, did not come from his lips.
Katsuki kissed him harder and threw his arms around him, looping them over his shoulders as Kirishima suddenly leaned up on his knees. Next thing he knew, he was falling back against the mattress with his best friend on top of him, his hard on painstakingly noticeable as Kirishima slotted himself between his legs, only breaking the kiss during the fall before crashing back into him.
Katsuki gasped into his mouth and kissed back reverently, arching up against his friend when feeling he was just as hard as he was, and-
“Fuck, K-Kirishima..!” Katsuki panted between kisses as the red head grinded down between his legs.
The friction felt fucking amazing and all of Katsuki’s blood had definitely finished rushing south from the stimulation, and damnit, Kirishima did it again. And again. And again. He was dry humping the shit out of Katsuki and Katsuki was clawing at his back, clutching his shirt tightly and rolling his hips with the movement.
Kirishima leaned his weight onto his forearm, that hand clutching at Katsuki’s hair while he used his free hand to suddenly roam down Katsuki’s front and grope at his pec. They both groaned into the kiss with the added touch, Katsuki’s mind going fuzzy and his breath hitching as Kirishima’s palm kept brushing his nipple as he kneaded the plush muscle.
Katsuki mewled and arched into the touch, pulling out of the kiss to pant for breath as Kirishima kept rocking against him and opened his eyes to meet his gaze. Katsuki shuddered at his fucked out expression, lips swollen and eyes blown wide with desire, every little thrust sending jolts of pleasure through his body.
Kirishima seemed to blush then despite everything as his hips slowed and he stuttered, “Ah, B-Bakugo, I-“
“No,” Katsuki growled, rocking his hips against him and earning a surprised, breathy moan from the red head that made his head spin, “You stop now, you die, Shitty Hair..”
“Fuck..” Kirishima rasped before rutting down against him hard and leaning into his neck, kissing and biting those sharp ass teeth of his into Katsuki’s skin.
Katsuki couldn’t deny the moan that slipped from his lips if he fucking tried as he clawed at Kirishima’s back and threw his head to the side, allowing the red head better access kiss and suck and bite into the sensitive areas that sent shivers down his spine.
“Fuck, fuck, fuck..!” Katsuki cried softly, not caring how depraved he came across anymore as he met each of Kirishima’s thrusts with the same urgency, “Kiri- Kiri please, m’close..!”
“Holy fucking shit..” Kirishima breathed against his skin, “Fuck, Bakugo, can I-“ He pulled up and looked at him, still frantically grinding down against him, “Can I suck you off? Please, please, Katsuki..”
Katsuki’s brain short circuited at his question, then completely went offline at the use of his first name from his best friend’s lips. Realizing he was at a loss for words despite a pitiful “Ah..!” he managed to get his body to respond for him and nodded dumbly.
Because holy fuck did he want that!!
Kirishima groaned at the consent, working his way down his body quickly and yanking his embarrassingly wet sweats and boxers off in one go, leaving him bare to his fully clothed friend. Katsuki would be mortified if it wasn’t for the fact said clothed friend was now between his legs and grabbing his angry red, leaking cock in his fist and eyeing it like it was his favorite meal.
Kirishima fucking groaned again when he finally made a move, licking a wet stripe up the underside of Katsuki’s shaft and making him writhe and grip the sheets, nearly falling apart right then and there. Thankfully he lasted long enough to feel the tight, wet heat of Kirishima’s mouth envelope his cock before he broke, not even able to mutter a warning as his back arched off the bed and Kirishima sucked and swallowed around him.
Katsuki shuddered and moaned little soft “Ah’s” with every breath as he rode out his high, all the while Kirishima kept his mouth on him and didn’t pull off until he’d milked him dry.
“Fuck, Kats..” Kirishima said between breaths, “I’ve always wanted to do that..”
“Huh?” Katsuki asked in a daze, feeling his face heating as he caught his breath. Fuck, he wasn’t ready for post nut clarity, what the hell did they even just do? They seriously crossed a line somewhere and stomped it into the ground never to be remembered.
“I like you.” Kirishima admitted, face turning equally as red as he crawled back over him, “Sorry for not telling you sooner, I should have confessed before things well, escalated.” He sighed and smiled a bit shyly, something sort of funny to see after the guy just sucked his soul out of his body, “Will you be my boyfriend, Kats?”
Katsuki swallowed and nodded dumbly again, his chest blooming with warmth and affection for that stupid, shark toothed grin of his, “Yeah, okay.”
Kirishima smiled even brighter then, a sight Katsuki would die for (yes, a second time) and crashed his lips into his with the easiest kiss of them all so far.
Katsuki pulled back then and fidgeted nervously, realizing the situation, “Ah, uh, d-do you want me to-“
“Already did.” Kirishima admitted sheepishly, easing off of him to show that ah, he totally came in his shorts.
Katsuki laughed softly and earned a smack on the arm from his now boyfriend before he leaned up to get dressed again.
The next day during rehearsal, everyone was shocked when the two easily stepped up to each other, bringing their lips together in a heated, passionate kiss that had Mina gasping and Iida stuttering and begging them to stop while the rest of the class proceeded to both cheer and freak the fuck out.
