Roomates

Denki Kaminari x F!Reader

Summary - You and Denki pair up to share a hotel room together while the class is on vacay😨

CW - Smut, first tim, teasing, sub! Denki, pervert Denki (ofc), mentions of alcohol,(🍃)

—————————————————————

The two of you are settled in the room you were sharing, you couldn’t believe Aizawa let a girl and a boy share a room together. To be fair, nobody else really wanted to room with Denki, especially for 5 days straight. You were stuck with him on this island, you wake up? He’s there, you go back to the room to chill, there he is again. You couldn’t get enough of this boy even if you tried, and he definitely couldn’t get enough of you. “{Y/N}? Heyyy, I know you can hear meeee~ come onnnnn!” Denki whines, shaking you out of your disassociated state. “Hmm? Sorry denks, I zoned *yawn* ..out a bit” he eyes you up and down, since it was the class’s first day on the island, your teachers didn’t plan anything for the class to do, which was relieving especially after a 13 hour plane ride.

He digs through his backpack, and pulls out a bag of opened gummy bears, “ew why do you have those, how long have they even been in there?” He smirks, pulling one out and popping one in his mouth. “Oh no, they’re new, just had to make them look like they were from the actual brand..” you lift an eyebrow, invested in what mischevious acts he got himself into. He gets close to your ear and whispers something, you gasp and cover your mouth “Denki! Oh my god you could’ve gotten in so much trouble at the airport!” hitting him in the back of his head, “..so you want one?” you smile “hell yeah I do.” He grabs another gummy bear from the pack, grabbing your jaw and opening it before slipping the gummy into your mouth. You had never really done this thing before, sure you had gotten drunk before back in middle school, but weed seemed so much more serious and it honestly kind of freaked you out at first. But you were with Denki, so if anything were to happen you were atleast with somebody you trusted. The two of you giggle over what you had just done and you grab his hand, he turns his head and gets up, still holding onto you. You wonder what’s going on in that pretty head of his, when all of a sudden he pulls away and jumps up in excitement.

“Let’s go swimming!” The loud boy exclaimed, his hands still on your shoulders as you sigh “Denki its like.. 10 p.m. shouldn’t the pool be closed?”. He gives you that look, that look where you know he’s up to no good, “who said we couldn’t sneak in?” you roll your eyes and laugh, as you get up from your bed and begin to rummage through your suitcase to find your swimsuit. Denki sits on his bed, taking his shirt off as you look in his direction, his swim trunks were already on, “oh you asshole you were planning this since we got here, weren’t you?” He flashes a guilty smile, “what can I say? I’m full of great ideas, honey~” You couldn’t help but laugh, walking into the bathroom to change into your suit. Your head starts to feel a bit tingly, but you ignore it, you can hear Denki losing his shit over nothing in the other room, ‘idiot’.

—————————————————————

10:31 PM. The two of you are tip-toeing downstairs, sharkng quiet laughs as he opens the door to the entrance of the pool. Of course, the gate is locked as you expected, Denki holds you up as you grab ahold of the top of the tall fence, throwing yourself over to the other side as you land on your feet, but then stumble onto your ass due to the height of the fall. Denki starts to tear up from holding in his laughter as he climbs over the gate, he loses his grip, falling straight on his face, “SHIT!” He yelps, you can’t breathe, laughing so hard it could be heard from the top floor, he shoots you a dirty look as he wipes the dirt off of his face, throwing you over his shoulder while your gaurd is off. “Denks? Denks what are you doing, no NO-“ He jumps into the cold pool with you, you kick him under the water as you stick your head up from the water gasping for air, “you really are such an ass!!” He swims closer to you, “y’know you love me, you can’t lie~” he gets close to your face, he’s one flirtatious dude you’ll give him that.

You’re face gets hot, your wet skin touching up against eachother, it’s like he’s staring into your soul. The both of you breathing heavy, the silence is painful and he gets even closer, your skin almost glued to eachother. That’s when you hear a somebody outside of the gate, “shit!” you grab his head and push it under the water, you do the same, the lights are off so nobody would be able to see you under there, right? Wrong, it’s Iida, Aizawa had heard the two of you and sent the class president chasing after. “I can see you two, what on earth were you thinking? Go back to your rooms, your gonna get us all kicked out!” He scolds the two of you as the both of you are giggling, pulling yourselves out of the cold water. “Oh Iida your no funnn” the electric boy whines once more, shaking the water from his hair, “you should be lucky, this time I won’t tell sensei. You two are off the hook..” he eyes the both of you, arms folded “..for now”, you and Denki look at eachother, almost rolling your eyes in sync.

—————————————————————

You both were sitting on Denki’s bed, after showering the two of you were exhausted, bored, and needed something to do. Denki turns to you, “hey {Y/N}?” you hum, looking over at him as you fiddle with your phone, “do you, like have a crush on anybody?” you smile, “why would you like to know, one of your buddies send you on a mission to pair me up with them?” he turns away, his cheeks a darker shade of pink. “N..no.. was just wonderin’” Your smile fades as you yawn, heading over to your bed as you hide under the covers, the two of you both still intoxicated as he starts to complain “come on don’t go to bed yettt, I wanna do something~” Too late, you were out cold by the time he walked over to you, “pfft, lightweight.” He continues to stare you down, thinking about what you were wearing, a pair of tiny sleep shorts, and a tank top from a band you both enjoyed, Denki had gifted it to you last christmas. He then stumbled onto his bed, still staring at you, he thought about how pretty, and how hot you were in your pyjamas, and especially how amazing you looked in your swimsuit. “..Fuck..” He looked down at his crotch once he noticed his pants felt tighter around him.

God it was so wrong, but so hot. He begins to palm himself, letting out tiny, sweet moans as he continued to stare at your sleeping body, maybe it was the weed, or maybe it was the long plane ride. But he wanted you so bad, he lets out a loud whimper, that sure as hell woke you up, you lift your head as he jumps up, removing his hand from his still clothed dick. “..mmm.. Denks? You okay..?” You rub your eyes, letting your eyes readjust to the light, eyeing him and his frazzled, embarrassed state. “Y..yeah don’t worry about me.. j-just go back to sleep, i’m perfectly f-fine..” He didn’t look ‘fine’, you uncover yourself and walk over to him, putting the back of your hand to his forehead, “you’re warm, Sparky..” he loved it when you used nicknames, it drove him nuts. He breathes heavily, hoping you don’t notice his little ‘issue’, but it was already too late, as you were eyeing him down to see what was wrong, you saw the tent under his pants, but you decide to save him from the embarrassment, instead you decided to tease him a bit. You slowly trace you hands down his body, “..you sure you’re feelin’ alright, Denks..?” he whimpers slightly, he craved more than that, he wanted, needed more of you. “You wouldn’t wanna be sick the entire trip, you gotta tell me..” you lower down, finally straddling him “..if somethin’ isn’t feeling right” you could hear his heart beating at an inhuman speed.

“Fuck.. {Y/N} ~ g-get off of m..me~ or i..i..-“ you grind against him slightly, “you what Denks? Gonna cream your pants over some friction..?” His hands trembling, holding your waist as he stares into your slightly red, half-lidded eyes, he leans in, and finally kisses you. All day you had been teasing him, everytime you were close to kissing, something messed it up somehow. You break the kiss, “Denks..” his eyes widen, “d-did I do something wrong? I-i’m sorry!” he removes his hands from your waist, you smile and kiss him again, pushing him down so your fully on top of him.

That sure answered his question, his hands are above is hands as he lets you do all the work, he liked you being in charge, your tongues slickly rubbing against eachother as you continue grinding onto him. Breaking the kiss again, you slink down so your head is leveled with the band of his shorts, “you want this.. Denki?” he whimpers, letting out a small “yes.. p-please.. i’m beggin’ you~” His body shaking, you untie the strings from his pyjama pants, you look up at him for permission, he lifts his hips up slightly. You pull his pants down, and then hook your fingers on the rim of his boxers as he looks away, you pull down his boxers to reveal his twitching dick, leaking with precum. You were honestly shocked by the length, Denki didn’t really.. radiate big dick energy.

You open your mouth and maintain eye contact as you lick a wet strip up his length, before lowering your mouth, taking his cock in slowly as a groan escapes from his mouth. His hand slapping over his mouth as you bob your head up and down, swirling your tongue around the tip every so often, “..babydoll, fuck.. you don’t know what you’re doin’ to me~”. A series of grunts, moans, and whimpers can be heard before you come up for air, a slight ‘pop!’ is heard when your lips seperate from his throbbing length.

“W-why’d you stop?” whining as you crawl on top of him, your hand intermingling with his as the other hand plays with his hair, he nuzzles his head in the crook of your neck as he moans softly. He opens his mouth, suckling on your soft, sweet skin “mm~ Denks.. want you..” you moan slightly, “..need you, inside.” Groaning, he takes ahold of your waist and flips you onto your back, still eagerly feeding on your skin, purple marks all over your neck and chest. He looks into your eyes before lowering his head over to your left breast, lolling his tongue out as he starts to harshly suck on your nipple “Denki, mmph!” You cry out, you needed him so badly but he just kept teasing you, this had to be payback from earlier, “..baby, you gotta be quiet.. can’t have anybody hear us..”

You try to hold back your sweet sounds as he moves his head back up, kissing you hungrily, growling into the kiss as he starts to pump himself slowly. You couldn’t take it, you rub your thighs against eachother, trying to create any kind of relief from the need of the electric boy inside you. “Stop fuckin’ with me, just do it already you bastard~” he smiles, removing his hand from his length as he gets closer, ripping your shorts and underwear off. You can feel the tip of his dick pushing up against your needy, wet folds. Inhaling deep as he slowly pushes through your entrance “oh.. fuck! {Y/N} f-fuck!” is all he could say, dropping his head low, you try to contain yourself, a mix of pain and pleasure.

You dig your nails into his toned back, deep breaths are heard as he sips fully inside of you, there’s a familar, comforting silence between the two of you for a moment, you both still, refusing to move until you look up at him, weakly nodding as that devious grin of his appears back onto his face. Show thrusts begin, pumping in and out of your aching core, the sound of skin slapping and lewd noises fill the room. “{Y/N}, god.. you feel so.. ahh~” He sobs out, you can’t contain yourself as you finally lose all sense of dignity, “Denki, fuck ahh- your so good..”

This was so beyond wrong, you had completely broken the trust Aizawa had reluctantly granted the two of you as soon as you got there. One of Denki’s hands were latched onto both of your wrists, which were above your head at the moment, your legs were wrapped around him tight as he thrusted faster into you, neither of you could hold back, especially Denki. You sucked on his neck, marking him as well, making him go crazy, you were his and he was yours and he made sure you knew that too. What a submissive boy this guy was, sparks of electricity escaping his body as his sweet, high pitched moans were ringing through your ears. He hid his face the crook of your neck again, embarrassed at the current state the two of you were in, his thrusts got faster, deeper as he choked on his own sobs, you were in a state of bliss, never wanting to leave this sacred moment.

You felt it, an unfamiliar feeling in your core building up, quickly too. The grip of your legs tighten as he moves his mouth closer to your ear “..c-can’t take any more.. I need to-“ A small whimper interupts him, “..mm~ gonna.. c-cum! can I- cum inside.. pl-please?” You can’t contain yourself, you pull your wrists away from his grasp as you cup his face, “Denks.. do wh- ahh~ whatever you want to m-me..” that sent him over the edge, harsh thrusts abusing your pelvis and thick ropes of his seed coat your insides, he throws his head back and lets out one last pathetic moan before you release, the feeling of his seed abusing every pleasureable spot inside your cunt finally snapping that. Clamping down on his sensitive cock as you release all over him, as you cry out a series of profanities, he quickly pulls out and collapses on the bed next to you, it’s silent once more, the only things that could be heard was the loud breathing the two of you shared.

“What did we just do?” He looks over at you, panting as he stares at you with those golden eyes of his. “..fuck?? make love? whatever you wanna call it..” You look back at him, before frowning as you feel a sense of guilt, “what does this make us?” He reaches for one of your hands and squeezes it “..what do you want us to be {Y/N}” it’s quiet for a moment, “Eachothers, I.. I love you Denks, I never thought I’d say it out loud.. I really love you.” He smiles, getting closer to your exposed body, “..I love you too {Y/N}, I want to be yours, forever.”

—————————————————————

The two of you had walked into the breakfast room of the hotel the next morning, holding eachothers hands as quite a few of your classmates stare at you. “Real nice you two, please! By all means, be as loud as possible, not like any of us couldn’t hear you.” Mina has her hands on her hips, scolding the two of you as you both look down in embarrassment. “Oh real subtle guys, have a lightup sign saying you guys finally screwed while your at it, huh?!” Mineta chimes in, pointing at the hickeys trailed along both of your upper bodies, you couldn’t help but laugh as Mineta still scolds the two of you as you cross your arms.

“Someone’s really jealous, should’ve picked a better roommate~”
