Notes Hey there!! I finally decided to pick up writing as a hobby again after I did an one-year break, I hope my style and grammar are moderately acceptable lol. I'm already apologising for typos/grammar errors in advance haha but anyways, I hope you'll enjoy this regardless!<3 See the end of the work for more notes "Hey, Kiri…"   "…hm?"   His voice is soft, a mere whisper, careful to not alarm any of his other classmates. "Do you… want to come to my room?"       Requests, instructions like that have been starting to become a frequent occurrence between Kirishima and Kaminari, and every time one of them invites the other to his room, they always know what they are going do. They know they'll end up fooling around in either of their rooms, but that's exactly what they intend to do, anyway.   It's not different today — after both of them manage to slip out of the common room into one of the elevators without anyone noticing them — it's especially difficult when Mina is around, but they somehow manage to sneak around her while she's gossiping with Ochako and Tsuyu — their hands automatically entangle as they arrive in the floor where Kaminari's room is located.    Intertwining their fingers has become some sort of ritual as well, and Kirishima squeezes Kaminari's hand hard as the blonde tugs him to his room, quickly fumbling with the lock until he finally manages to push the door open.   Kaminari briefly turns his head to flash Kirishima a smile — it's small and kind of shy, which is honestly extremely cute, and his cheeks are bright red already, but then he locks eyes with him and he'd be lying if he said he couldn't relate to the desperation, the hunger in his boyfriend's eyes. God, he wants to kiss him so badly.   However, Kaminari's expression is enough to make Kirishima's face flush a decent shade of pink before he pushes the blonde back who stumbles into his own room with a short, surprised gasp, the other boy following him and immediately closing the distance between them.    Kaminari stands with his back against the door, trapped in between Kirishima's arms which are on either side of his shoulders. The redhead swiftly pushes his bangs back (he's wearing his hair down today because he ran out of hair spray, much to his own dissatisfaction) and looks around in Kaminari's room — it's messy, but not messier than usual, his bed is not made either (which isn't that much of a problem right now anyway), the blinds are drawn, letting the warm, faint light of the setting sun in.   "…hey, Eiji", he hears Kaminari saying and turns his head to look back at the blonde who is slightly pouting, his hair a little more mussed than usual. "How long are you still gonna stare at my room?" He hesitates for a split second. "Kiss me already."   Kirishima can't help the grin that immediately spreads across his face before he finally leans in, one hand coming up to cup Kaminari's jaw. He closes his eyes after he sees Kaminari doing the same and presses their lips together in a chaste, soft kiss. He hears and feels the blonde sigh as he pushes back, arms coming up to wrap around Kirishima, his hands caressing his shoulder blades as he pulls him closer. Their lips move together in a loving dance, a perfect balance of receiving and giving pressure to the other's mouth.   Kirishima can't deny he likes starting slow when doing those kinds of things with Kaminari, but going fast isn't bad, either. Soon, their slow and gentle pace vanishes and Kirishima's hand wanders from Kaminari's cheek to the back of his head, threading his fingers through blond locks as the other sighs again. Their rhythm starts becoming a little sloppy as the redhead tilts his head and parts his lips a little to press open-mouthed kisses against Kaminari who squeezes the other's shoulders, whimpering softly as he gives in, opening his mouth as well as their kiss grows more heated.   Both of their breathings become ragged as Kirishima's tongue peeks out and traces Kaminari's bottom lip who reflexively opens his mouth wider, ready to welcome his boyfriend's tongue in his mouth. Kirishima sighs at the reaction, feeling his face grow hotter and a spark of pleasure traveling down his spine as he slips his tongue into Kaminari's mouth, pushing closer as the other whimpers while reaching back with his own. Their tongues entangle for a second before he pulls back, earning an irritated whine as Kaminari chases after him with his mouth.    The blonde's hands reach up and caresses the hair on Kirishima's neck with his fingertips.    The redhead sighs and leans in again, this time his tongue immediately darts forward and Kaminari moans softly as he mimics Kirishima's movements.   Kirishima moves his head in a rhythm, pushing forward and pulling back slightly, his tongue stroking against Kaminari's who clings to him desperately, arms tightening around his boyfriend's shoulders in an attempt to pull him closer, to pull him flush against him.    "Nh… ah", Kaminari inhales sharply as their tongues push together and Kirishima's sharp teeth graze his lower lip. It doesn't hurt; in fact, it tickles slightly and Kaminari shudders up as pleasure surges within him. Their kiss is sloppy and wet and it leaves him breathless in a way he can't get enough of.   Kirishima presses their bodies together, one hand gripping at Kaminari's waist while the other is still buried in his hair and tilts his head to the side, just a little bit, and pulls the collar of Kaminari's shirt towards his shoulder to have better access to the other's neck as he starts trailing kisses along his jaw and throat.   The redhead can feel the other boy's moan rumbling in his throat before he even hears it, and moves further, peppering pliant, open-mouthed kisses all along Kaminari's neck before he latches his lips on to his soft skin and sucks.   "Ah— fuck, Eiji." Kirishima doesn't miss the way the blonde's hips twitch as sharp teeth sink into velvet skin and he sucks harder, just barely pulling back before he draws blood. Kaminari's skin is pretty thin and breaks easily, especially on his neck area, so he has to be careful.   He observes the way Kaminari's pale skin turns a slight red-purplish colour, forming a new, fresh hickey over the layer of older, fading ones before he cocks his head to be met by a desperate gaze. Kaminari's cheeks are flushed red, his lips swollen and glistening with saliva and god, his eyes are dark and clouded with desire and Kirishima absolutely adores that look on Kaminari's face.   Warmth pools in the pit of his stomach as he shudders, diving right back to suck at the new hickey before moving further and sucking at the junction of Kaminari's neck, earning a desperate gasp and another twitch of his hips. He grazes his teeth along the smaller teen's collarbone, leaving small marks all along the way before he presses soft kisses against the bruised skin.   "Denki…" He sighs as he feels hands curl tighter into his locks, the slight pain of his hair being pulled causing him to tremble in pleasure. "I love you."   "Eiji…" It's a breathy whisper, maybe even a plea, and he grips Kaminari's waist harder. He hears the blonde swallow. "Eiji. C'mon."   Kirishima raises his head to give Kaminari a questioning look through his red bangs, just to be met by soft, slightly wet lips again. He groans as the blonde rakes his hand through his hair and licks at the corner of his mouth, but instead of slipping his tongue in, he pulls away to gaze at Kirishima.   With his beautiful flushed face and swollen lips and needy, hooded eyes, even though his expression looks a bit softer this time.   "God, Eiji, I love you so much."   Kirishima can feel his heart swell at the way Kaminari says that — in fact, it swells because it's Denki who says it, anyway.   The smaller teen doesn't even give Kirishima time to reply, he just pulls him down again to kiss him. It's slower than their previous kisses but it's still unbearably hot, especially as Kaminari nips at his lower lip while the redhead feels up his chest. Kaminari's hips stutter once more, a sweet aah, slipping through his lips as Kirishima's fingers trace his areolae, and god he has to bite the inside of his cheek to keep himself from moaning and rutting against Kaminari.   Instead, he finally slips a thigh in between Kaminari's thighs and the blonde immediately grunts, pulling away from the kiss to angle his face downwards and stare down at their aligned crotches and the room immediately feels dozens of degrees hotter.    "Can I start moving?" Kaminari hears Kirishima asking him in a husky whisper, and he shifts his gaze, seeing that the redhead looks just as breathless as he sounds.   Kaminari has to bite back a moan as his hips move without his permission, grinding his crotch into Kirishima's kneecap which is pressed against the front of his jeans. "F-fuck, yes."   And Kirishima finally shifts, slow and deliberate, pressing closer, rubbing his thigh up against Kaminari's groin. The blonde lets out a shuddering gasp as his hips buck unintentionally against his lover, stretching into a moan as Kirishima actually moves with him, stirring nothing but pure pleasure in both of them.    Kirishima shifts and adjusts a little, still with his leg pressed in between Kaminari's thighs as he starts kissing him again, slowly, leaving him enough space to gasp for air while he keeps rubbing his knee against Kaminari's crotch.   The blonde moans as Kirishima breaks their kiss to gasp for air, and pushes his hips forward, feeling the redhead's erection pressing through the fabric against his hip and Kaminari's own cock pulses in response as he realizes he's just as hard as he himself is.   They soon lose their rhythm and just start humping against each other, hard and fast, hands and knees pressed against each other's crotches in frantic, desperate movements, the heat between them slowly becoming too much, their pants and moans echoing in the room.   "Ngh—ah", Kirishima moans as he struggles to keep himself up, the pleasure surging through his entire body making his knees weak. "W-wait, wait a second." He gasps and forces his hips to halt.   "Wha-what's wrong?" Kaminari asks, lust clouding his vision but still managing to stop the desperate humping.   Kirishima doesn't answer (at least not verbally), as he takes Kaminari's hand and drags him over to his bed while wriggling out of his shirt, the fresh air cooling his overheated body. He lets himself fall back against the cushions, pulling Kaminari with him who immediately sits up, straddling Kirishima who  grabs his hips.   Before the taller teen can even think of starting to move his hips again, Kaminari stops him.   "No wait, I, um…" He bites his lip.   "Huh? What's wrong babe?" Kirishima props himself up as well, eyes not leaving Kaminari's face.   Kirishima can't really read the blonde's expression, his face is still flushed with dark eyes, but he looks some sort of… embarrassed? Bashful? Nervous? He immediately worries that he did something wrong and already opens his mouth to apologize but Kaminari cuts him off.   "I-I was just thinking if you could do…" He swallows and wriggles a little. Kirishima tries his best to ignore the sharp pang of pleasure in his groin at his movements. Whatever it is that Kaminari wants him to do, if it makes him happy, he'll do it.   "C-could you do… y'know…" His voice gets quieter at the end as he curls his hand and jerks his wrist up and down, his face flushing, but Kirishima doesn't really know why. They have fooled around like this before, and yes, they have gotten each other off by using their hands too, so why is Kaminari so embarrassed about it?   "B-but like, you do it to yourself, and uh, I watch."   Oh.   Oh.   Kirishima has to admit that he did not expect that.   Kaminari quickly raises his hands at Kirishima's baffled expression, trying to laugh it off. "But you don't have to! It's perfectly fine if we just do it like usual—"   But Kirishima already rolls him over carefully so he's the one to look down at his lover, pressing a quick kiss against his lips before withdrawing, resting with his back against the headboard. Kaminari looks at him timidly, questioningly, and the taller boy nods, unable to suppress a grin at Kaminari's alarmed yet turned on expression.   He shifts his eyes down to his own crotch, seeing how his erection presses up against the fabric of his jeans.   He quickly peeks up at Kaminari who sits on his knees in front of him, hands grabbing the bedsheets, and sees how his gaze is fixed on Kirishima's crotch as well, sees how he unconsciously licks his lips. It just urges him on, seeing Kaminari so horny and desperate to see him jacking himself off, even though it is in fact a little bit embarrassing.   Kirishima slowly presses a palm against his groin, feeling his erection through his jeans and grunts at the sensation. It feels good, finally getting a hand fondling his dick, even though he'd like it better if it was Kaminari's.   His hand slowly caresses the skin around his navel, slipping his fingertips below the waistband of his pants before he unbuttons and unzips his pants, pulling them down mid-thigh, his erection visibly straining his boxers. There's already a wet patch of precum where the tip of his cock lies.   He hears Kaminari's breath hitch as he reveals the prominent tent and looks up, seeing how his boyfriend has crawled closer to get a better view. Kirishima spreads his legs a little and Kaminari looks up as well, only to see that the redhead has been staring at him and quickly turns his head away, flushing.   Kirishima thinks he's kinda cute like this, embarrassed but needy and he really, really wants to give his boyfriend a reward for being so adorable, so he gropes himself through his boxers, fingers finding the outline of his erect dick and his hips snap up at the contact while he lets out a deep, guttural groan.   His head thumps back against the headboard, eyes lidded and vision blurry, only barely able to see how Kaminari turns his head to stare at Kirishima again.   The taller boy's hips rise from the bed to push his boxers down as well and they bunch along with his jeans below his knees so he can still keep them open enough for Kaminari to see. He's all worked up, his cock hot and heavy as it's fixed flat against his lower stomach, precum smearing the tip.   He himself knows his dick's physique pretty well, but Kaminari stares intensely, taking him in, which is embarrassing since he's the only one with his dick out, and maybe he's high on dopamine or something but Kaminari gazing at his cock like that turns him on like nobody's business.   Trying to blink the cloudiness in his vision away, he sees how Kaminari bites his lip and his cock twitches at the sight.   Kirishima finally, if slowly, wraps his hand around the base of his cock and bites back a moan, hips already shaking with pleasure. He grips tighter, sliding his hand up torturingly slow, breath catching in his throat as he finally reaches the wet tip of his dick. A shudder whacks through him as his thumb and index finger rub around the head, against the slit, fingers already threading with precum.   "Oh god", Kaminari chokes out, and Kirishima tries his best to focus on the silhouette in front of him, watching his dick pulsing with need. He's still on his knees, but he's clasped a hand over his mouth, fingers only barely hiding the deep red blush staining his face.   It's the last thing Kirishima sees before he tilts his head back with a ragged moan, palm rubbing against the head of his dick in circular motions, before sliding it down, spreading his precum across his length. His hand twists at the base, squeezing himself hard, and he growls as his hips snap up, fucking himself once, twice into his hand.   "Damn, D-Denki", he stutters, followed by a throaty ahh as he moves his hand up and down, slick, wet noises filling the room along with his breathless groans and gasps as he humps against his hand. His sharp teeth sink into his bottom lip, trying to muffle the wanton noises coming deep from his throat. It feels so good, finally chasing his release after being worked up so much, and imagining that it's Denki who does this to him actually makes it better.   Since Kirishima has his eyes closed, he's able to concentrate more on the noises, the movements Kaminari makes, and as he calls out his name, he swears he can hear him moan along with Kirishima. His fingers skate across the burning hot skin, feeling the skin ripple and stretch with every up-and-down movement while he listens to Kaminari's uneven, laboured breathing which sounds so hot to him right now, he can't get enough.   His hand twitches as he starts moving faster, just barely twisting, only sliding up and down his length, his hips following the movements of his palm while he sometimes lets out a deep moan, breathless and needy and he'd literally do anything to just get Kaminari's hand on his dick already, but if he can't get that right now, doing it himself is the best solution.   His cock is so hard it almost hurts, sometimes it throbs when he hears Kaminari's sighs or when his breath hitches, it sounds so delicious to him and only makes him want to move faster, pumping his hand while imagining it's Kaminari's softer, smaller hand rather than his.   He imagines how Kaminari must look right now, since he's too busy to open his eyes. He's probably blushing harder than ever, worrying at his own plush bottom lip as he stares with hooded and needy eyes at Kirishima's moving hand, his hard dick. Maybe his own hips move a little, humping the air, or grinding against the mattress, or maybe he has a hand on himself already and the thought makes Kirishima's dick throb.   Kirishima groans deeply as his cock twitches in his hand, wrist aching already, but he can feel the pleasure coiling deep in the pit of his stomach. He tries his best to pick up the speed, thumb rubbing against his slit every time his hand jerks up. He an feel the tension in his stomach gathering at the tip of his member.   "Denki, g-god", Kirishima chokes, the hand that's not on his dick coming up to muffle his groans. "'M, ah, gonna cum…!"   Kirishima feels drunk off the feeling, he can't get enough, and actually wants to continue ruthlessly fucking into his fist but suddenly, Kaminari grabs his knee, slipping forward and trying to stop him.   "Wait, Eiji, wait a sec— ah, fuck…", he grits out, grabbing Kirishima's wrist to stop him.    The redhead's hips stutter up until he comes to a halt, his expression dazed as he slowly opens his eyes, staring at his boyfriend through his red bangs that stick to his sweaty face. He can see Kaminari, even though his vision is still a bit blurred, but god he's so beautiful,  his blush still prominent and dusting down from his face and ears to parts of his neck, and for some reason, he looks just as breathless as Kirishima, even though he still — Kirishima's gaze drops down to Kaminari's crotch — yes, Kaminari doesn't look like he has touched himself yet.   "W-we can, I mean", he clears his throat. "Can we do it together? I don't think I can hold it in any longer…"   Kirishima immediately groans and nods frantically, hell, now he knows why Kaminari wanted to watch him masturbate because just the thought of the blonde doing it almost makes him come.   Kaminari slowly pulls his pants down along with his underwear while Kirishima sits up again, trying to ignore the throbbing in his dick, reminding him that he's about to cum by a hair's breadth.   But he's immediately rewarded by Kaminari's cock springing free and Kirishima almost whines as he sees the other's erection.   He doesn't know if the words "cute" and "pretty" are appropriate words to describe your boyfriend's cock, but he can't deny thinking that as his eyes take Kaminari in.   It's a bit smaller than his own, and flushed in a different shade than his; while Kirishima's own dick is a crimson red down to the base, Kaminari's is flushed a soft pink that slowly fades downwards, his whole member dripping wet with precum and sweat. He's just as hard as Kirishima is himself and he's careful not to get his hand back on his dick again — not until Kaminari is ready.   But the blonde wraps his hand around the shaft and the whine he lets out is enough to make Kirishima shudder violently, moaning along with his boyfriend as Kaminari twists his hand eagerly, desperately, already looking like he could come apart any second.   "God, Denki, you're so cute", Kirishima groans, his own hand finding his dick again, pumping slower than his boyfriend so he has time to catch up. "Just look at you, you're so cute, ah—"   He can hear the smaller teen calling his name wantonly over the erratic throbbing of his heartbeat, a sweet "E-Eijirou—!" that makes his core seize up and his muscles spasm. Kaminari calling out his full name had always been intimate to him — usually he was just called abbreviations of his name like Kiri in public and Eiji when they are alone.   Watching Kaminari desperately jerking his dick and listening to his breathless moans and whimpers is like watching art unfold. His blonde bangs stick to his sweaty forehead, his whole face is flushed in blotchy shades of red and his swollen, pink lips are parted as he pants his boyfriend's name over and over while rubbing against his slit.   Kirishima can't help but mimic Kaminari's movements on his dick, finally picking up the pace to match it with the blonde's whose hips have started twitching irregularly, hand struggling to pump in time with his desperate thrusts.   "Ah, mnh, E-Eijirou", he rasps out as he throws his head back, his eyes rolling back in their sockets, shaking and panting as his hand twitches up his dick and squeezes hard around the head. "G-gonna cum—!"   Kirishima has troubles keeping his eyes open, with his own wrist and dick aching and he's so fucking close to tipping over the edge that Kaminari's voice alone could've been the cause of his wrecking orgasm but his hand applying pressure to his dick only adds more feeling as he finally comes apart, cum spurting hard and heavy between his fingers and dripping onto the sheets while releasing a string of guttural, breathless moans.   He needs a few seconds to calm down and come down from his high and almost forgot that Kaminari still has to finish. He shoots up despite every single muscle in his body telling him to rest and hopes, hopes that Kaminari isn't done yet, and in fact, Kirishima finished just in time to see the blonde rolling his hips up one last time before releasing, one hand holding his shirt up while he other is still clasping his cock, continuing to rub himself through his orgasm as his cum shoots out, spurts of white painting his abs and hands as he shudders through it.   Kirishima bites his lip hard and slumps back against the cushions as he watches Kaminari coming down from his high, gasping for air and hands shaking.   Although his legs and hand feel sore, he sits up and grabs Kaminari by his sides, pulling him into an embrace and back against the pillows as the blonde collapses on top of him, still trying to regulate his breathing.   "Denki…" Kirishima search for his boyfriend's lips and Kaminari moves with him, even though he almost seems too exhausted for kissing right now. "I love you."   "Mmh", Kaminari hums, pulling up his boxers that were still bunched up mid- thigh. "Love you too."   Kirishima notices that his own pants are still around his calves as well and ponders if he should pull them back on or off, but then settles on kicking his jeans off and only pulling his boxers up. It's too hot to be wearing anything more than underwear right now, anyway. He also notices that they haven't cleaned up the mess they made yet, which is kind of embarrassing, so he tries to wriggle out of Kaminari's grasp but he holds him tight against him.   "Don't go", he whispers, eyes closed. "Stay with me."   Kirishima's heart skips a beat at the way Kaminari says that but cuddling with cum on their bodies is still kinda gross, even if it's their own stuff, so he reaches out for the tissue box Kaminari has on his night stand (obviously) and tries his best to clean their hands and stomachs.    He isn't exactly sure how late it is and how much time they spent fooling around, but the sun has already set and faint moonlight is coming in through the window into the room. Kirishima slowly settles his chin against Kaminari's head and pulls him closer, entangling their legs and reaching for a blanket to toss over their bodies while Kaminari's arms are winded around his torso, keeping him close. It seems like he'll sleep here tonight since Kaminari doesn't make a move to get up nor letting Kirishima go, but it doesn't bother him anyway.    Kirishima sighs contentedly, raking one hand through Kaminari's blond hair while the other wraps around his waist.    He should also change Kaminari's bedsheets tomorrow.
