But maybe they were in love all along. Notes why is everything in mha so shippable urg. too many ships, not enough ideas. anyway, this was inspired by the song summer by brockhampton. comments are always appreciated. enjoy~   Eijirou isn’t exactly sure what kind of response he expects when he invites Bakugo on summer vacation with him. He’d just been talking to himself mostly, explaining why visiting his grandmother’s home out in some country town by the beach would be mind numbingly boring.   The sighed, “It would be so much better if you were there. Come with me?” had slipped out completely on accident, before his mind could even process exactly what he was saying and to who exactly he was saying it to.   Knowing Bakugo, he half expects the usual “Shut up, hair-for-brains. I’m not your therapist” to be spat out.   His mind is already playing the image of Bakugo storming away behind his eyes.   But what Eijirou definitely doesn’t expect is the softstare. No knitted eyebrows, no scowl. Just that blank face stare.   And then the “okay.”   Eijirou almost does a double take. This wasBakugo right? The same Bakugo that yelled at him daily for being too loud and obnoxious. The same Bakugo that he could only definitely count on for last minute cram sessions because the other blew off most planned hangouts with their classmates involved.   ThatBakugo was agreeing to spend a whole week cooped up in a tiny town with Eijirou and nothing to do?   Eijirou almost can’t stop the “Are you sure?” that wants to shoot from his throat as a much louder than necessary yell. But he does stop it because he doesn’t want anything to ruin this once in a lifetime unabashed, honest  acceptance by Bakugo.   “Cool, dude,” Eijirou says instead, letting a huge grin split across his face.   Bakugo is still staring, that same passive stare that tells Eijirou he’s doing something right.   There’s a beat of silence between them and Eijirou watches Bakugo’s eyes slide across his face awkwardly. His smile falters a bit because, that’s a little weird isn’t it? He gets slightly self conscious under that piercing gaze and begins to wonder if he has something on his face.   Eijirou absently wipes at the corner of his mouth and then Bakugo’s eyes are darting away.   The rest of their walk to the dorms is silent. But sometimes Bakugo’s silence spoke more honesty than any words could. A week later and they’re all packed and ready to catch their train. Eijirou doesn’t exactly get the sly remarks Kaminari and Ashido make about their trip together. Stuff about them “getting closer wink wink”.  They’re already as close a Eijirou could have ever hoped and he’d never force his way any closer to Bakugo than Bakugo wanted.   The train ride goes by in a blur. Eijirou never realized what a difference just being with someone could make.   Though Bakugo isn’t as much of a talker as he is a heated yeller, he listens well. Eijirou goes on and on about memories from summer’s passed. He describes the rocky beach landscape in detail, talks about the kids he used to play with summer after summer until he was the only one left.   Bakugo provides interjections. Calls him a “dumbass” in the stories about him fucking around and hurting himself. Sarcastically says “fun” in stories about helping his grandma fish or get market goods for the cheapest price with bartering.   Eijirou is somehow even able to coax a story out of Bakugo about his own childhood summer experiences.   Bakugo talks about swimming nude in a backwoods steam with some chumps he hung around in middle school.   “We should do that,” Eijirou giggles out, caught up in the image of a pre- pubescent Bakugo pridefully showing off the few pubic hairs he probably had growing back then.   When Eijirou doesn’t get a response he tenses up for a second, wondering if he had gone too far but a quick glance at Bakugo shows that he hasn’t angered the other.   “Wouldn’t you like that,” Bakugo finally replies, his tone a gentle scoff, accented by the twitching scowl upturning his lips ever so slightly.   Bakugo turns his head away from Eijirou and looks out the window next to their seats.   Eijirou takes this as a message to stop talking so he looks around Bakugo’s head and out the window himself.   He hadn’t realized how much time had passed and he’s surprised to see the expanse of rolling hills and empty fields rushing by in a smear of green.   He stares for a while until he hears Bakugo grumbling.   “Your shitty reflection is blocking the view, ass,”  Bakugo mumbles emptily, sounding more disinterested than biting like he usually would.   “Oh, sorry,” Eijirou replies mindlessly.   He makes to move his head and angle it more behind Bakugo’s own but he hears another mumble.   “Was only joking, shitty-hair. Stop taking me so seriously.”   It’s a drowsy mumble that makes Eijirou thinks Bakugo is drifting to sleep. But the words are what sticks to him the most. Eijirou had never known Bakugo to “joke”. Of course most of his insults weren’t 100% serious but it was hard not to take Bakugo seriously.   Eijirou had experienced his nature, similar to that of a ticking time bomb, full force for himself. Certain things just set Bakugo off for reasons Eijirou would probably never know. But he was fine with trying his best to read Bakugo. Trying his best to keep the other generally appeased.   But this, this  concept of joking, it was new. And Eijirou couldn’t help but grin at the back of Bakugo’s head. He was entering new territory and that was progress he wouldn’t trade for anything in the world. They arrive only a half an hour later, hobbling out of the train and onto a completely desolate platform with one suitcase and one backpack each.   The distant smell of the ocean hits Eijirou hard. It’s salty and intoxicating and so very different than anything he could ever smell in the city. It’s hot out, and bright. And although Eijirou usually hates the sticky feeling that the humid sea breeze brings, he can’t help but find it a bit comforting this time.   “Ah, the bus stop is a five minute walk up the road. It comes by every twenty minutes  so we may have to wait a bit,” Eijirou blathers, starting to walk towards the steps at the back of the platform.   He’s on the first step when he looks back over his shoulder to see Bakugo still standing in the middle of the platform, head turned to the right and looking off into the distance.   Eijirou stares for a second. Takes in the way the natural light bounces off of Bakugo’s pale skin. How his blonde hair becomes a halo as the light shines through it. He looks good. He always looks good.   “ ‘s nice, I guess,” Bakugo mumbles, letting his gaze linger on far off scenery for only a moment longer before turning forward and beginning to walk in Eijirou’s direction.   Eijirou is still staring and Bakugo has no problem snapping him out of it.   “Fuck are you staring at,” he snaps in a raised voice.   Eijirou doesn’t answer. He knows he doesn’t need to answer when Bakugo says stuff like that. Answering only hightens his sometimes feigned annoyance.   So Eijirou just turns back around and continues walking, his face flushing. Maybe because he was caught gaping at Bakugo or maybe from the heat. He can’t really tell. They only wait ten minutes before the bus is there and the ride to the neighborhood his grandma lives in is only twenty minutes more.   When they arrive at the old styled, traditional Japanese home that belongs to Eijirou’s grandmother, Bakugo seems to be at a loss for words for once.   “Holy- I didn’t know the place was going to be this fucking big. The way you talked about this place made me think it would be a fucking shack!” Bakugo yells out, clearly surprised.   Eijirou grins at him sheepishly.   “Well, no matter how big a place is, if there’s no one around it’s lonely as hell.”   Bakugo doesn’t reply but Kirishima can see the way his face falls just a bit, seemingly understanding those words perfectly well. “Eijirou!” his grandmother greets as they enter the main hall.   She’s as tiny as ever, only coming up to their shoulders, and she has to stand on her tip-toes to get her arms around Eijirou’s neck comfortably.   Bakugo watches the exchange, not expecting much, but then Eijirou’s grandmother turns and gives him the same lopsided hug.   “You must be the Katsuki boy he’s told me so much about. Just as handsome as I imagined,” she rambles on, taking a few steps back and looking the pair of them over.   Eijirou holds his breath for a second, but he can tell Bakugo isn’t phased by her dotting in the slightest   “I’ve set up your old room with two futons, Eiji. I hope you two don’t mind sharing a room, I just thought it would be easier for you both to be close to the front,” she continues.   Eijirou nods and after a bit of the usual small talk about school and hero training, he leads Bakugo to their room. “So you call me Katsuki behind my back, huh?” Bakugo sneers when they’re finally able to put their stuff down.   Eijirou’s skin prickles a bit at his tone, Bakugo doesn’t sound upset per se, but Eijirou can’t help but think he shouldn’t have done that.   “Ah, sorry-” He starts, busying himself with unpacking some of his clothes, but he’s cut off.   “’s fucking fine, just let me call you Eijirou,” Bakugo grumbles over his apology.   Eijirou feels his face heat up. They’re that close now?   “Okay! That’s fine K-Katsuki,” Eijirou tests out.   He turns his head to smile at the other only to see Baku- Katsuki turning away with just a tiny tint of red creeping up the back of his neck. Eijirou snickers to himself. The sun is just about to set by the time they’ve finished unpacking everything and have settled in. Eijirou decides to give Katsuki a quick tour of the neighborhood that mostly consists of tiny stone alleyways winding past various houses, some big, some small.   It ends up being more of a walk than a tour, because Katsuki is slightly ahead of him and Eijirou becomes more interested in the beauty of golden hour than pointing out little things here and there.   They pass a shrine and turn down one last spirally path before they’re at the beach.   “Wow, swear it’s prettier every single time,” Eijirou says, skipping ahead.   He kicks his sandals off and starts running towards the shoreline, leaving Katsuki somewhere behind him.   The retreating sun casts a deep bluish shadow over everything and the bit of sun left paints a long stretch of the sky orange. It looks gorgeous. The sound of crashing waves takes Eijirou back to days when he was too young and innocent to understand much about the world. To days when he would run across this very beach in the dark with sparklers in hand and five other boys his age in tow.   He runs right up to the water and kicks around in it a bit before turning around to see Katsuki walking towards him slowly.     He swears he hears Katsuki mumble out the word “pretty” while staring directly at him. And his face probably flushes a pretty deep orangey red that rivals that of the fleeting color painting the horizon. But luckily it’s masked by dark shadows.   “Hey Katsuki,” Eijirou asks when the other is finally close. His voice is slightly muffled by the sound of crashing waves, but he can tell Katsuki has heard him.   He lets his call for attention hang still in the salty air for a moment as the last peak of the sun starts to recede faster.   “Why’d you decide to come with me so easily? I thought you’d hate stuff like this. Hate staying with me in for such an extended period of time,” Eijirou finally continues.   A bit of surprise flashes across Katsuki’s face for an instant, but it’s gotten too dark for Eijirou to really read it.   “Why would you think I hate being around you? You’re the only one I’d ever tolerate this much,” Katsuki grumbles with his eyes shifted passed Eijirou and set on the ocean waves behind him.   He has this weirdly worried scowl etched into his face and Eijirou would do anything to wipe it away.   Eijirou’s heart skips a bit as a delayed reaction to Katsuki's words. Worries of being a bother to Katsuki wash away with the outward pull of the tide.   “You know me, I’m dense as hell. You have to spell things out for me or else I won’t get it,” Eijirou says back sheepishly, a nervous laugh gurgling in the back of his throat and coming out as a cough.   Silence.   Katsuki is always hard to read, but even so Eijirou considers himself a bit of an expert at it at this point. And yet, standing here alone in the dark with the sound of splashing seawater as their background music, Eijirou has no idea what  Katsuki could possibly be thinking.   His face is only slightly illuminated by a distant moonlight that reflects off of his pale skin and leaves a bit of a shimmer in his eyes. And Eijirou finds himself thinking that Katsuki is pretty too. Maybe Eijirou had been joking when he said he wanted to swim nude with Katsuki and maybe he hadn’t been.   But either way, it happens. There’s an abandoned dock farther up the beach than where they had stood the night before, and Eijirou leads Katsuki there just after breakfast.   “Why’s it so fucking empty around here? I’d expect more people to be around with weather this nice,” Katsuki says on their trek back down the same winding stone pathways.   “I guess people just forgot about this place or something. When I was a kid, there were always people on the beach or in the market. But these past few years it’s been deserted. It’s pretty sad to watch a place change so drastically. It feels like I’m the only one left who still holds those memories so dearly,” Eijirou replies.   Eijirou can see Katsuki looking at him from the corner of his eyes. He wonders if he’s coming off as a bit melodramatic so he turns his head and flashes Katsuki a little smile.   But Katsuki’s head snaps forward before Eijirou has even completely turned.   There’s a slightly weird atmosphere floating around them that’s been settling in ever since the night before, and Eijirou can’t help but think Katsuki had been acting uncharacteristically strange for even weeks before that. It’s weird that he hadn’t been able to notice it sooner.     Maybe Eijirou was denser than he thought. When they arrive at the dock they just mull around for a bit, sit with their legs thrown over the edge, and let the breeze swirl around them for what feels like an eternity.     Then Katsuki says it.   “We should go for a swim.”   The nonchalance of the statement gives Eijirou a start and for a second he doesn’t realize what Katsuki is implying. They haven’t bought any swimsuits nor towels. When the realization of the exact implications hit Eijirou, he turns to look at Katsuki, only to see the other looking straight ahead with an unreadable expression screwed tight into his features.   “You want to?” Eijirou asks carefully, watching closely for any slight reactions that he never sees.   “I’m the one that suggested it, aren’t I?”   Eijirou watches quietly with bated breath as Katsuki stands up.   He just stands there a second before kicking his sandals off to the side and tugging his black tank top off.   Eijirou can feel his face heating up. He’d seen Katsuki shirtless plenty of times before in the school locker room and even in the communal bathroom in their dorm. But Katsuki was even more majestic with the backdrop of the baby blue sky, clouds floating around behind his head, making him look like a classical painting of a greek god in the sky.   Eijirou feels his mouth go dry. He knows he's staring and he knows that Katsuki knows he staring. Katsuki pulls his pants and underwear down in one quick swoop soon after like it’s no big deal, but Eijirou can see the deep red blush speckling across his chest and spreading up towards the edge of his neck.   “Holy shit, you’re big,” Eijirou blurts out stupidly, his eyes dropping down to Katsuki’s crotch.   Katsuki looks like he’s struggling to keep from covering himself with his hands due to Eijirou’s scrutiny.   But he caves and lets his left hand slide in front of his junk while turning his head to hide the blush spreading across his nose. But Eijirou can see it nonetheless.   “Fuck are you staring at, you never seen a dick before?” Katsuki mumbles gruffly.   “Where was I supposed to see one, other than in porn,” Eijirou asks with his head tilted to the side.            Katsuki looks like he legitimately doesn’t know what to say to that. He stares at Eijirou’s face intently like he’s searching for something but when he doesn’t see it he looks rather taken aback.   “You mean, you’ve never, like, looked at any of us in the locker room when we’re showering and shit? Never?”   Eijirou looks scandalized.   “What? Why would I do that? It’s totally unmanly to invade another dude’s privacy by gawking at his unsuspecting dick in the locker room!”   There’s a beat of silence between them and then Katsuki laughs.   Bakugo Katsuki laughs.   It’s high pitched and awkward and uncharacteristically cute.   He’s covering his mouth so Eijirou can’t see whatever smile he may or may not have playing on his lips, but the sound itself is more than enough to make Eijirou’s stomach tighten.   “Get naked you prick, before I change my mind,” Katsuki barks out between snorts.   And Eijirou is quick to take his orders. He all but rips his own clothes off. And though he doesn’t expect Katsuki’s eyes to slither up and down his body, they do.   “You’re not too bad yourself,” Katsuki says with a final smirk before hopping off the dock and into the ocean.   Eiijrou all but beams and quickly follows suit.   It’s the fourth night when it finally happens.   It. They’re both tossing and turning in their respective futons. It’s a hot night. Sticky and gross, uncomfortable in all the worse ways.   Katsuki keeps cursing under his breath and that definitely isn’t helping Eijirou drift off into the semi-comfort of sleep.   They keep to themselves for what seems like hour.   And then   “Eijirou,” comes Katsuki’s hoarse voice, sounding groggy and tired but still slightly angry.   “What?” Eijirou replies in a similar tone, though there’s no anger laced between his words like in Katsuki’s   “I can’t fucking sleep,” Katsuki mumbles.   Eijirou stifles a laugh.   “I can see that,” he replies, rolling over so he’s facing Katsuki, whose body is already turned and facing his direction.   They stare at each other for a long few moments. Eijirou tracing what little he can see of Katsuki’s face through the dark with his eyes and Katsuki returning the gaze with his usual neutral stare.   They meet each other’s eyes finally, and Eijirou sees things behind layers of purposely dulled expression that he’s not quite sure how to interpret.   “Katsu-,” he starts, but he’s cut off by Katsuki voice, mirroring his own words.   “Eijirou.”   “What?” He says back again, still lost in Katsuki’s eyes, searching through galaxies unexplored, finding so much he can barely handle it.   “Eijirou, I like you.”   Eijirou can feel himself heating up far beyond a healthy temperature. He momentarily wonders if Katsuki just means he likes him as a friend. But Katsuki’s gaze shifts right before his eyes and reveals far more about his intentions. Reveals everything about everything.   “Katsuki,” Eijirou replies dumbly, suddenly breathless.   To think it was this easy all along. To think falling in love was so simple that it could happen without either of them noticing, without either of them realizing. To think.   Eijirou’s brain feels like it’s short circuiting. Buzzing to the tune of the cicadas chirping outside, a muted hum fuzzing out everything else with no thoughts able to break through that static white noise.   Eijirou’s body acts on its own. He leans forward and kisses Katsuki hard.   He’d never kissed anyone before so it starts awkward, their lips just sat there over each other’s. Then Katsuki moves his mouth and adjusts the angle and suddenly their lips are fitted together perfectly and their mouths are moving harmoniously.   He thinks he could kiss Katsuki like that forever.   Their bodies feel sticky as their hands start to fumble over each other’s bare biceps and their torsos somehow become pressed together firmly.   Eijirou gasps for breath first and then Katsuki is kissing his neck and letting his hands slip up under Eijirou’s tank top.   “Katsuki, wait, I’ve never, never done this,” Eijirou pants out, nerves suddenly baring their ugly head.   Katsuki stops and lifts his head back up to look at him.   “Neither have I. Sorry if I’m moving too fast. But, fuck, you’re so damn hot. Don’t know how I kept my hands to myself when we were swimming. Wanted to touch you like this.”   Katsuki’s breath fans out hot and heavy over Eijirou’s face and he feels arousal taking over the last rational part of his brain.   “‘s fine then,” Eijirou mumbles back, puffing his own hot breath into Katsuki’s face.   Katsuki resumes action, but slower this time. He continues to slide his hands up under Eijirou’s tank, peeling it off of sweat slick skin. His fingertips trace across defined abs, swiping over every dip in the muscles.   “Fuck, you’re ripped,” Katsuki breaths out pecking Eijirou on the lips before continuing to slide his hands even farther up   His fingertips brush against nipple and that’s all it takes to get Eijirou to gasp, loud and breathy.   Katsuki smirks at him and continues the assault, rolling each nub between his fingertips harshly, pinching them hard periodically. And Eijirou continues to groan, letting his hand fall over his crotch as inconspicuously as possible. He rubs over himself slightly, bucking his hips into the light friction. But of course Katsuki notices.   “Just let me suck you off if you need it that bad,” Katsuki says playfully.   Eijirou groans, deep and guttural, and allows  Katsuki to move his hand and replace it with his own.   “This hard just from a little making out?” Katsuki teases with an eyebrow quirked.   He gropes Eijirou through his shorts. Rubs his fingertips over everything tauntingly and squeezes at Eijirou’s balls.   “K-Katsuki,” Eijirou all but whines.   His hips start to jerk wildly at the feathery touches. He wants more friction. Needs more.   Katsuki suddenly picks up pace. He shoves a hand down Kirishima’s pants and pulls his dick out, pushing the waistband of the pants down and out of the way just enough.   He scooches down so that Ejirou’s dick is aligned with his face and he gives Eijiou’s hardness a tentative nudge with his nose.   Eijirou’s thighs quiver in anticipation, and he can’t help the incoherent babbling that falls from his lips     “Damn, never expected you to stink so good,” Katsuki whispers, nosing at the bush of pubic hair at the base of Eijirou’s dick.   Eijirou’s lets out a breathless giggle, squirming under the fluttery sensation of Katuki’s nose rubbing over him.   “I don’t really stink though, right? I swear I showered last night. Even used soap,” Eijirou rambles between his last few fading laughs   “I said it was a good stink, didn’t I? Super musky and manly and all that shit,” Katsuki says, looking up at Eijirou as he licks tentatively at the tip of the cock before him.   Eijiro whines, maybe because of the sensation, maybe because of Katsuki’s backwards compliment, and maybe because of both.   But either way he’s already gone.   Katsuki shifts them around so that Eijirou in on his back and Katsuki is between his knees.   And then he takes Eijirou fully in his mouth.   It’s sloppy. A mess of spit and precum everywhere, but that just makes it all the more hot. Katsuki trying to get Eijirou as far into his mouth as possible and all but choking himself on the length is damn near the sexiest thing Eijirou has ever seen.   It’s clear how inexperienced they are. Katsuki mimicking things he’d seen in porn and failing at them but still getting a rise out of the textbook virgin beneath him. And Eijirou not even knowing what to do with his hands until Katsuki guides one of the fists at Eijirou’s sides to grab at his hair.   But even though it’s awkward and new, it gets them both worked up beyond belief.   “Fuck my mouth like a manly man, or some shit,” Katsuki slurs halfway through with Eijirou’s dick poking the inside of his cheek.   “O-Okay,” Eijirou replies quickly, leaning back fully and placing both of his hands gently on the back of Katsuki’s head.   Eijirou awkwardly bucks up into Katsuki’s mouth. Once, Twice. Then he does it a third time, but thrusts far too hard and deep.   Katsuki starts to cough and sputter and pull away and Eijirou just cums, hips twitching up into the retreating heat.   His cum mostly dribbles down Katsuki’s chin, who continues to cough and wipe at his watery eyes.   “God, Katsuki, I’m sorr-” He starts, only to be cut off by Katsuki jumping on top of him and slipping a hand over his mouth to shut him up.   “Y-You really think I can’t even take that much? ‘m not weak,” Katsuki garbles back, his throat sounding all fucked out   They stare at each other for a bit. Katsuki letting his hand fall from Eijirou’s mouth and Eijirou bringing his own hand up to smooth through Katsuki’s hair. It’s that silence that speaks louder than most things that Katsuki ever says. The fondness moving across his face tells Eijirou everything he needs to know.   “I like you too, Katsuki.”   “As If I didn’t know, dipshit,” Katsuki grumbles back, before snuggling into Eijirou’s chest like his was meant to be there all along. When they get back, Ashido is the first to know that they’re a thing. Not because they tell her, but because she catches them holding hands on the way back to the dorm and self proclaims herself as the aunt of any of their future children.
