All The Rumours Are True (I Fuck Him And You)

Summary:

“Prove it.”
“I will!” Denki doesn’t even question his retort until after he’s said it.
———
Denki hears a rumour about Shinsou through the grapevine. When he goes to Monoma to confirm it, he finds himself tangling the three of them in a complicated web of feelings without even knowing it.

Notes:

I use masculine terms for Denki’s genitals (dick, hole, etc) btw 👍🏻 Trans Denki is my favourite thing ever as a trans denki Kinnie so boop

Chapter 1: Bad Decisions, Good Feelings

Chapter Text

Really, it’s probably his own fault for being a little too gullible with his giant heart. Denki has always been a romantic, with a big helping of teenage horniness that zaps his braincells away from him as much as his quirk did.

But he’s gotten better! He’s in his third term of his final year and he’s improved drastically with his quirk since his first year. His voltage tolerance is higher and his aim is pretty much a bullseye 85% of the time. He’s ready to become an on-duty full time hero and save people with his classmates in the world of Pros.

More than anything, he can’t wait to be the future underground hero, PuppetMaster’s, biggest fan! Heck they might even work together sometimes!

Denki plans on being a pretty vocal fan of all his friends, but Shinsou holds a special place in his heart. Specifically, he holds the whole damn thing.

Denki can’t pinpoint when he fell for Shinsou, but after he finally got the boy to acknowledge their budding friendship in second year, it was a downhill slope for Denki.

Shinsou listened to indie punk and heavy metal, he loved cats and was always visiting the shelter on his off days to play with them, his humour was dry and snarky and he was extremely attractive. Especially in action.

Denki’s heart didn’t stand a chance when faced with that cheeky, soft smile every time Denki squawked at his playful insults.

Befriending Shinsou opened Denki’s friend group up too. Big Hands and Steel Shark became quick friends with him. Blondie, the loud mouth, fought it for a long while but sometime in the beginning of third year he seemed to mellow out with Denki. He was Shinsou’s closest friend after all, and Denki liked to think he was a close second. A truce had to be made eventually, for Shinsou’s sake.

Monoma being Shinsou’s closest friend though was probably why Denki went to him when he heard the rumour.

Denki had been trying to work up the courage to ask Shinsou out for ages. It was mostly a promise he made to himself during the high after his top surgery. If he can go under a scalpel to get rid of his flesh sacks, then he can ask out his stupidly pretty boy crush!

So when he hears from the grapevine (aka Mineta, who could write a gossip paper if he ever retires from being a pro with how much juicy informative he has) that Shinsou doesn’t date, only fucks, he’s shocked. At first he tries to reason that maybe he could try and change that — he’s never been against the idea of casual sex, but he does prefer the idea of a real romance. Maybe he could make Shinsou fall for him along the way. But then the kicker comes.

“Apparently he refuses to fuck virgins though; what a loss, man. Who wouldn’t want to fuck a virgin?” Mineta sighs like a disapproving parent and Denki wants to bury his face in his hands and wail dramatically like a five year old.

Denki didn’t think he’d still be a virgin by third year, honest. But his first year in UA he was still adjusting to his shots and felt terribly uncomfortable with the idea in practice despite his constant horniness (and hunger — god, he would have starved if not for Kacchan cooking for him most days, even if he complained that Denki would get fat and then continue to pile more on).

In second year he tried to overcome it, feeling a bit more comfortable with his body. So he asked out Jirou. And it was a great two months, he was certain he was in love, but then… Well, it turns out he’s so bad at kissing that he turned her into a lesbian — or so she likes to joke. In truth, she realised she loved Yaomomo and apologised profusely when she ended things with him. Denki had tried to negotiate at first, he really did love her after all. She had shut it down quick though when he said he still had the stuff she liked.

Probably wasn’t the best way to come out to his girlfriend, but it hadn’t ever come up in conversation and Denki often just forgets he has to come out. Most of his friends who know only found out because of him cracking trans jokes.

Denki had been touched when she said he was still a boy, that she didn’t like them, and that what he has or doesn’t have didn’t change that. And then proceeded to awkwardly admit that she was a trans girl but didn’t feel comfortable telling everyone yet because they all thought she was cis. It’s probably one of the reasons they’re still so close after the break up, besides her rocking personality, of course. The solidarity kept them close. It took him a bit to heal, but soon after he got closer to Shinsou and well, the rest was history.

So Denki still remained a virgin unlike half his disgustingly in love classmates. He was pretty sure Mineta was still one too, but that didn’t count for much.

“Are you sure?” Denki asks once more for reassurance.

“That’s what I’ve heard, man. Shinsou gets in on with pretty much anyone who asks, but never virgins. Heard it with my own ears from someone in his class.” Mineta tuts and grumbled about his own lonely status.

“Ah.” Denki, as much as he trusts Mineta on the battlefield (and with his porn stash), decides then and there that he needs more proof. So he goes to Monoma, because who would know better than Shinsou’s best friend?

So Denki finds him during a free period that he knows Shinsou spends with Aizawa. Tetsutetsu and Kendo were usually training with their own partners during that time too; Tetsutetsu had been pumped to test Aoyama’s limits recently with his quirk, as well as his resistance, and Kendo had been trying her best to beat her reptilian girlfriend in battle and improve her agility.

Everyone was excited to be applying for agencies and it made them all restless, Denki figured.

So that left Monoma alone every Thursday during their shared free period. Denki was a great strategist! Suck on that, Mina.

“Yo! Ken Doll!” Denki grinned, wide and cheeky, and Monoma only spared him a deadpanned glare. He looked tired, and considering he roomed next to Shinsou, maybe the rumours were keeping him up. Denki tried not to laugh at the thought.

“Ah, I see you’ve decided to grace me with your presence, how can I be of service, your highness?” Monoma drawls, loud and mocking. Yet somehow Denki can sense the teasing. Monoma doesn’t like to show many others, but he is a good guy. He’s kind, calm, intelligent (even if he struggles academically as well, something that had brought them closer as friends) — he’s got the makings of a pro hero and he’s vocal about it in all the wrong ways, in Denki’s opinion.

“I do need your service actually,” Denki laughs, feeling a little nervous suddenly. He scratches the back of his neck, an anxious habit he can’t kick. He knows Monoma will know of his feelings for Shinsou if he asks about the rumours, but he’s also fairly sure he would keep it a secret if asked.

“Oh?” Monoma actually gives him his full attention now. A rare occurrence. Monoma is a multitasker, almost habitually. It’s a sweet gesture, and Denki feels his heart warm at it. Monoma really could be a good friend when needed, no wonder Shinsou kept him around.

“I, uh…” Denki felt his cheeks heat as he cleared his throat, spying around the fairly empty room. There’s only one other student there, earbuds in. “I heard this rumour. About Shinsou.”

“Ah, you do have working ears.” Monoma hums, obviously waiting for more. Denki pouted.

“Look, I just want to know if it’s true. If Shinsou really doesn’t date and only, uh, fu— fucks.” Denki cleared his throat once more. “And the things about no virgins.” His face burns now and he adverts his eyes to avoid Monoma’s observant blues.

A long moment passes before Denki hears Monoma snort, turning back to watch the boy stifle a laugh into his palm.

“What? Hey, stop laughing at me! It’s just what I heard, okay?!” Denki grumbled, embarrassed beyond belief.

“You — You want to know the truth?” Monoma looks up at him — his eyes are a vibrant baby blue and they swirl with cunning — and Denki can’t look away as he waits on the edge of his seat. He nods, bright eyes wide with curiosity.

Monoma’s smirk twists into a razor sharp grin, his eyes darker as he leans in. He looks sinister and Denki thanks the heavens that Monoma uses his quirk for good and not evil, because he’d be a truly terrifying villain if he tried.

“Shinsou does sleep around. But he doesn’t fuck virgins because…” Monoma chuckled, barely containing himself it seems. “He doesn’t want to make them cry because they can’t handle him.”

Something tells Denki that Monoma is fine with making his partners cry from his tone, and quickly waves away that thought because he doesn’t want to stew on whatever weird kinks Monoma might have.

“Can’t handle him?” Denki furrowed his brows in confusion. Denki doesn’t like to think ill of Shinsou considering he really likes him, but he does start to wonder what crazy kinks he might have with that kind of logic. Was he — oh god, did he use his quirk on people in the moment? Quirkplay wasn’t terrible uncommon, but still, handing complete control over to someone like that and not being able to break free while they order you around and use you for their sick fantasies…

Denki shifts uncomfortably before taking a proper seat besides Monoma, ignoring the flash of heat in his gut. He should put that thought away for after he’s dating Shinsou.

“Well, I can tell you, but you have to promise not to tell Hitoshi I told you.” Monoma picked at his nails in a bored manner and Denki whined, shoving his arm like a child.

“Don’t be like that! I won’t tell a soul! Cross my heart!” Denki crossed over his heart and he saw the twitch of a smile on Monoma’s lips before the other schooled his features and turned back to Denki.

“I asked ‘Toshi the same question you did. Why don’t you sleep with virgins? Isn’t that most guys fantasies? You know what he said?” Monoma rolled his eyes as Denki visibly anticipated the rest of the story. “He told me that he didn’t fuck virgins because he’s got a monster down there, and he doesn’t want to ruin their first time if they can’t take it.” Denki gaped.

“What? No way. There’s no way that he’s really…” Denki flushed.

“Yep. I’ve seen it once, in the changing rooms.”

“Then…” Denki put his hands together and slowly pulled them apart. Monoma quirked a brow before a look of understanding came onto his face. He watched as Denki continues to move his hands out slowly. “Surely…” Denki stopped for a moment but Monoma shook his head with a look of amusement. Denki felt his face burn as he continued and suddenly Monoma gave a nod and shrug and Denki covered his face with his hands. “Holy shit.”

“Yep.”

“So— he won’t sleep with virgins because he’s — he’s big. Very big. Okay. Um… no exceptions?”

“Nope.” Denki visibility deflated. He knew he should be intimidated by the new information, but more than anything he felt dejected. He really liked Shinsou, but if Shinsou didn’t date and he wouldn’t touch a virgin…

Denki sighed. Monoma suddenly burst into laughter and Denki’s face burned.

“What the hell are you laughing at?! Frickin’ loudmouth.” Denki grumbled.

“You’re a virgin? Still? We only have one more term left after this before we start working. At this rate you’ll be a virgin until you retire,” Monoma continued to snicker into his hand. “Good luck trying to convince Mr Bleeding Heart to take it,” Hitting the nail on the head, Denki felt a rush of frustration run through him.

“Fuck off! I could take it, virgin or not!” He huffed. Monoma scoffed.

“Please, you’re such a crybaby that you wouldn’t even be able to handle me.”

“I bet I could considering you probably have a baby dick!” Denki stood and puffed his cheeks as he tried to hold in a scream of aggravation. Monoma’s eyes narrowed up at him, a sly smirk curling on his lips.

“Prove it.”

“I will!” Denki doesn’t even question his retort until after he’s said it. He freezes in shock and slaps a hand over his mouth as Monoma grins. Denki growled loudly and stomped his foot in his irritation before he turned to leave. He hoped running away would make Monoma forget it all (he was the kind of prick who liked to embarrass him though, so unlikely).

“My room, tonight, if you’re not chicken, virgin!” Monoma laughs after him and Denki takes back every nice thing he’s ever thought about the bastard.

— 💛💙💜 —

Denki’s good at convincing himself to do stupid things. It could be the ADHD speaking, but impulse control? Nonexistent.

So when he ends up stewing on Monoma’s offer (was it an offer? Maybe it was just a joke?) the rest of the day, he knows he’s going to go. Against his better judgement, the idea solves his main issue right now.

If he can get rid of his virginity, then he can sleep with Shinsou and seduce him into a relationship with his wild charm. The plan is still vague, but he’s working on the details! It’ll all end in a badass career, a wedding and a kid or two anyway. Plus, if he can handle Monoma than he gets to shove that in the blonds face. He was not a crybaby, that asshole. He was just a little sensitive to videos of cute animals and funny bones!

That how he ends up at Monoma’s door right before curfew. He’s showered and dressed comfortably, but maybe he’s wearing his tightest boxers and he’s possibly done some maintenance downstairs. If this goes through, it’ll probably be a funny story he can tell over drinks when he’s older — and him and Monoma will laugh about it because Denki does intend to keep contact with everyone once they all graduate.

It doesn’t occur to him until after he’s knock that Monoma probably doesn’t know he’s trans. Is Monoma one of those gay guys who only likes ‘the real thing’? Monoma can come off judgemental, but Denki is certain Monoma will be nice about it if he’s not into Denki’s quote-unquote ‘male box’. For all he knows, Monoma might be bisexual or pansexual.

Denki’s pretty sure he’s gay though.

“Kaminari?” Monoma sounds vaguely surprised, his hair still wet from his shower. He’s wearing baggy grey sweatpants that hang low on his hips, the branded waistband of his navy boxers peaking out. Monoma tousles his hair roughly, pulling it down around his shoulders as he looks at him head on.

“You told me to come.” Denki tries for a chill tone, but Monoma simply blinks at him. He looks caught off guard.

“Uh. Come in then, I guess?” Monoma steps aside and allows Denki inside his room. The walls are decorated with photographs and art work from kids; Monoma was surprisingly well loved during his time studying under Centipeder (Mount Lady had tried to recruit him too at the time but Monoma had held strong on the idea of working with Juzo who taught him a great deal of wisdom and technique — and how much his body could handle when it came to copying less humanoid quirks like the Pro’s). Apparently kids loved his magician look and asked him to do tricks with their newly developed quirks. Aside from the decoration on the walls, there is little else different about the room. His desk has a photograph of what looks to be a sister; it’s blurry but the elementary school uniform and the two pigtails tells him she must be young, or the photo old.

“You know, I didn’t actually think you’d have the balls to come.” Monoma says with his back turned, flattening his partially dried hair with a hand and tossing his towel in a hamper in the corner.

“I don’t have literal balls but I have a fuck ton of figurative balls.” Denki gives finger guns out of habit, stomach swirling with anxiety as Monoma pauses and turns to him with a perplexed expression.

“I’m trans. Trans man specifically. I kinda just… forgot to mention it. Is that still cool? I know some people can be icky about certain parts, you know.” Denki shrugs, nervous as he shuffles his feet and Monoma actual snorts.

“I really don’t care about that. I like guys, and you’re a guy, so I don’t care if you have a dick or not. Wish mine was customisable.” Monoma snickers. Denki is flooded with relief and finds himself laughing too. “My sister, she was — is — too. But it’s not important. Uh, if it’s okay to ask, have you had any surgeries done? I imagine training is hard with those— those chest things on all the time.”

“A binder. And yeah. I had top surgery before third year started up. Healed up pretty well so far.” Denki didn’t linger on the topic of his sister, seeing it might be a sore subject. Instead he takes the opportunity to strip off his shirt and show off his scars. They’re still pink but the tenderness is long gone and with the creams he uses the scarring should become barley noticeable with time.

Monoma’s eyes slide over Denki’s chest, the scars, before dipping lower to his lean stomach and up over his toned arms. Denki’s cheeks bloomed pink at the ogling and cleared his throat.

“So… what now?” He asked meekly, trying to calm his racing heart. It was surreal really. Denki was going to lose his virginity to Neito Monoma of all people. His crushes best friend, he realises. Hopefully that’s not awkward in future. Shinsou doesn’t have to know who it was if Monoma thinks it’ll be a problem.

“I guess now…” Monoma moved to his door and the lock clicked shut. Denki felt a spike of heat in his gut, anticipation making his heart pound as Monoma crossed the room to stand toe to toe with him.

Denki hates that Monoma got another growth spurt over the break. Monoma had only been maybe half a centimetre taller before third year, closer to Denki’s height than Shinsou’s, but now Denki had to actually tilt his chin up to meet his eyes when they stood like this. Denki was sure if he was an inch taller he’d tease Shinsou about being shorter than him, but alas, the universe let Shinsou have the win of being just that slightest bit taller.

“I can do this,” Monoma’s hands are warm against his face, cupping it gentler than Denki would have thought he would. He doesn’t hesitate to kiss him, which makes Denki flounder for a moment. He hasn’t kissed anyone since Jirou and they didn’t really get past a little bit of tongue. In the end, Jirou didn’t want to make out with a boy, so Denki was left without much experience in this area.

Denki’s eyes fall shut, focusing on the sensation; Monoma’s lips are soft and a little waxy — chapstick? — but his kiss is sweet. Denki’s hands slowly slip around his neck, needing a place to put them as Monoma nips his lower lip and curls a hand around his waist to pull him in closer. Denki sighs into the kiss, heart still hammering as Monoma’s tongue glides along his, slow and weirdly sensual. It feels strangely intimate, and Denki’s nerves sparkle at the intensity that feels like it shouldn’t be there for a one night stand.

Denki gasps as Monoma pulls him flush against him, feeling the broad chest and the tapered in waist and the stirring in his sweatpants. Denki feels a little dizzy at the contrast of a hard body against his and the gentle, languid kiss thats stealing his breath away.

Monoma’s hand brushes lower, hooking a thumb into his loose sleeping pants, and Denki rises onto his toes without breaking the kiss to help him pull them down. Denki inhales sharply at the groan Monoma let’s out, his other hand cupping his ass and holding him there. Denki feels the hardness grinding faintly against his hip and moans quietly as his body thrums with a wave of want.

Why was Denki nervous? This was great. He wishes he gave into his horniness earlier, the hormones were onto something.

Denki kicks his pants off after they’ve fallen to his feet, letting himself be led backwards; Monoma’s hands are on his ass and he’d giggle if not for Monoma’s tongue being halfway down his throat.

Denki squeaked as he tumbled back onto the sheets, lips still tingling like the rest of his body. It takes him a moment to clear his head enough to look at Monoma, noticing his touches had stopped. He looked up at the other hero and felt his cheeks burn as he watched Monoma’s dark gaze roam over his body.

“You know, you’re quite pretty. I’m surprised ‘Toshi hasn’t broken his rule for you.” Monoma makes it sound like an after thought, like he’s talking to himself, and Denki’s thigh twitches with the urge to rub them together.

“Well he won’t, cause I’m a virgin. So stop talkin’ about him when we’re… doing this.” Denki looked away as he spoke and he heard Monoma chuckle.

“His loss. I’ve always liked playing with pretty things more anyway.” Denki’s stomach flipped at the comment and gasped as Monoma’s lips pressed small kisses against his chest. Everything about Monoma is soft, gentle. He doesn’t pull or pinch or bite. At most he scrapes his teeth against one nipple and soothes the mild burn with his tongue until Denki is squirming. His chest had always been sensitive, but one nipple had gotten even more sensitive after surgery while the other got less. Relearning that part of his body had felt weird by himself but it felt just as strange with another person. Heightened even, embarrassingly so.

“You’re so red. And it goes so far…” Monoma’s finger trails over his throat and down to his nipple, giving it a light tug. “Cute.” He sounds genuinely pleased and it makes Denki’s stomach roar with butterflies. He throws an arm over his arms as he tries to cool his flush, Monoma’s tongue dragging down his stomach as he trembles.

“Don’t hide. I like watching your face.” How does he say things like that? Isn’t it embarrassing? Denki simultaneously wants to die of embarrassment and beg for more of his compliments.

Denki gasps when his hand slips into his boxers, and Monoma pauses. He doesn’t move his hand, simply stills and waits.

“Is this okay?” Denki takes a moment to respond. After all, that was the end goal. He didn’t have much dysphoria in regards to his downstairs, but that was just around himself. He hadn’t ever shared that part of himself with others and it felt a little daunting but also… exciting?

“Yeah. Yeah, it’s okay, just… don’t, um, I’m not a girl, okay? I’m still — still a boy.” Denki nibbled at his lower lip and Monoma chuckled softly.

“I know. You wouldn’t be in my bed if you were a girl.” And somehow, that does make feel Denki better.

Monoma pulls down his boxers slowly, like he’s waiting for Denki to back out, but Denki let’s his legs fall apart and they fell away. Monoma doesn’t linger on looking at it, which Denki appreciates, instead going back to kissing his lower stomach, hands roaming over his hips and thighs.

Denki whimpers as Monoma’s lips skip over his sex and instead lands on his inner thigh, kissing and biting gently as he throbs. He wants nothing more than to reach down and get himself off, but he doesn’t want it to end either.

“I wonder…” Monoma murmurs and Denki makes an inquiring noise before he yelps, Monoma’s teeth sinking into his inner thigh and leaving a deep red imprint that he soothes with his tongue.

“That hurt!” Denki grumbled, ignoring the desire to ask for another on the other thigh; for symmetry, of course.

“My apologises, darling.” There’s a hint of teasing in his smug smile and Denki has half a mind to kick him. He doesn’t get much of a choice though considering Monoma’s attention draws back to what’s between the thighs he’s nipping at.

Denki can’t help the groan that slips from his throat as fingers dance across his folds, pressing into the wetness coating them. A finger sinks in with ease and Denki moans softly, looking down shyly at Monoma who watches as a second finger gets sucked in besides it.

“Don’t have to worry about lube.” Monoma jokes to himself with a slight smile and Denki rocks his hips into his hand without a second thought.

“Come on, I’m dying here.” Denki whines, panting as Monoma smirks and thrusts his fingers deeper, watching Denki’s face now.

“So impatient, I’m learning new territory here, you know?” Denki wants to pout but it hard too when a fairly attractive blond is rubbing his walls in a way Denki could never reach. Denki whimpered and let his head fall back against the sheets, spreading his legs further.

That seems to be all the encouragement Monoma needs because suddenly there’s a tongue against his dick and he moans so loud he has to cover his mouth and pray to god that no one heard him.

“Wow, that was something.” Monoma grinned. “Keep moaning like that, darling, I like continuous feedback.”

Denki doesn’t have enough time to retort before that tongue is back against his dick, sucking and licking as his fingers stretched and curled inside him. His body was shaking, overwhelmed by the sensations as he muffled his moans against his palm. He felt like he was burning from the inside, pleasure curling in his gut like a wildfire.

“Fuck, ‘m gonna cum, shit,” Denki gasped out as his thighs twitched in the urge to wrap around Monoma’s neck and keep him there until he finished.

Monoma doesn’t stop. In fact he sucks harder and Denki can feel the tidal wave ready to crash when he hears a sharp, “ow!”

Denki cries out as Monoma pulls away, the wave falls apart and he groans into his hands. It takes him a moment to look down at Monoma, feeling a little cheated. He’d been unbearably close.

“Why’d you stop?”

“You zapped me!” Monoma defends himself, a few strands of his hair standing on ends.

“Oh.” Denki sudden feels rather guilty and rubs his neck sheepishly. “I forgot I sometimes do that. I’m usually alone so I’ve never… thought about it. Sorry.”

“It’s fine.” Monoma rubs his tongue along his teeth; it must have zapped his tongue specifically. Denki’s glad he didn’t bite it off all things considered. “I’ll just copy your quirk before you start going off again. I’ve built up enough resistance by now training with you.”

“Huh?” Monoma’s grin is back and he practically pounces between Denki’s legs to lean down and kiss him passionately. Denki groans against his lips and let’s himself be pulled back into the previously lost mood.

He can feel Monoma’s clothed cock against his stomach as they kiss and its noticeable enough that Denki speaks up.

“So, you gonna take those pants off so I can prove you wrong?” It’s cheeky and it’s earns him a graze of teeth against his jaw before Monoma relents and stands up to push down his pants. Denki pulls himself up into a sitting position so he can take a look and tries not to openly gape.

Denki fears for his guts if Shinsou is even bigger than Monoma.

“What was that about me having a baby dick?” Monoma quirks a brow at Denki and Denki wants to shut the fucker up. Apparently pulling him closer and wrapping his lips around his dick shuts him up pretty well.

The taste is strange; saltier than his own taste and a little bitter. But it’s bearable and Denki finds he doesn’t mind bobbing his head, sucking softly like it’s a candy. Denki just has to remind himself that he can’t bite down on it like he would a stim toy.

“Gods, you’re so fuckin’ pretty like this.” Denki burns with the praise, sucking harder and trying to take more as Monoma’s hand runs through his hair. “Looks like your mouth is good for things other than talking; should’ve made use of it earlier.” Denki knows he should be offended but his body throbs at the idea, having a cock in his mouth whenever he won’t shut up, it made his blood thrum with desire for more.

He gets too enthusiastic and ends up gagging and pulling off to cough, blinking back tears and wiping drool off his chin. When he looks back up at Monoma he feels a shiver run down his spine at the intense gaze.

Monoma’s fingers graze along the lump of his throat as he keeps his gaze, leaning in close to run a thumb along his wet lower lashes.

“You look pretty when you cry. Makes me want to ruin you so I can kiss them away.” His heart is pounding in his ears as he’s guided in for a kiss, nerves alight as he melts into it.

“Then ruin me.” It’s no louder than a whisper but it may as well have echoed, that way Monoma freezes and takes in a shaky breath.

“How do you want it?” He finally asks and Denki swallows audibly.

“I wanna ride you.” Monoma groans and kisses hard — harder than before and Denki moans into it as he sinks his fingers into the lean muscles of his shoulders.

“Do we need a condom?” Denki realises that’s a very good question once his brain catches up with him.

“I got the rod in my arm a few months back — I knew I’d just forget to take the pills — but we can use one if you want. You’re clean, right?”

“I’m all good.” Monoma kisses him once more, deep and passionate as he pulls Denki into his lap, breaking the kiss slowly as he laid back against the pillow. “Whenever you’re ready, cowboy.” He says cockily and Denki smacks his chest with a huff.

It’s a little daunting when he looks down at it; Monoma looks to be of average thickness, but he’s long and Denki both wants to back out and leave, and sit on it and let it fill the ache deep inside him.

He hovers over it and grinds himself against the length of it experimentally. They moan together at the feeling, and that gives Denki just enough courage to face the beast head on. At least when riding him Denki could pick his own pace.

Denki holds the cock in his hand gentle before he angles it at his hole and tries to slowly lower himself. It slips once, twice, but the third time is the charm, the head popping into with a soft gasp from Denki.

Unlike his fingers, Monoma’s cock takes up more space, the stretch uncomfortable as Denki rolls his hips gently to try and get himself to relax. There’s a slight sting for just a moment before something gives and suddenly he feels too full too quickly.

“Ah…” He takes a moment to breathe, looking down to see he was only halfway through. He refused to look at Monoma’s face as he swayed his hips, working his way down slowly. 

Denki yelps when Monoma tips his balance, sinking down on the last of his cock with a whine. He squirms at the feeling, clenching around the intrusion as he panted.

“You dick,” Denki huffed and Monoma grins at him.

“Come on, I thought you wanted to take ‘Toshi. You can barley take me,” He laughs and Denki flushed with humiliation.

“I’m taking you just fine! Just gimme a minute!” Denki bit his lower lip as not to pout like a child. After taking a few moments to just breathe, he let his hips roll and rock slowly, picking up speed. He can hear the soft breathy moans Monoma makes and it feels like victory. He could get used to this feeling, the fullness, the minor power trip. He felt electric, pun not intended.

Denki gets lost in the little movements, the quiet moans, until he feels Monoma’s hands under his thighs. He made an inquiring noise before he yelped, shifted up and shoved back down on his cock.

“That’s more like it, darling. I like it when you’re loud.” Denki can’t hold back his obscene noises when Monoma is fucking him onto his cock, hard and deep yet too slow and it makes Denki want to cry at the torturously paced pleasure. His nails find his chest — pale and unblemished and slightly muscular; the result of having to build up stamina for certain attack quirks like Midoriya’s.

There’s a single, almost vanished scar from his left collarbone to his right nipple and Denki wants to ask but not now. Instead he just digs his fingers into the muscle and scratches up the pretty canvas in his pleasure.

His skin crackles and Denki fears that he’ll stop but he gets zapped back instead. It feels different than his own electricity, a constant crackle of warm energy, and hits him like a hot, sharp smack. Denki trembles with every new shock, Monoma not stopping the sparks as he fucks up into him.

“Fuck, look at you. You’re gorgeous, all spread out like that. The prettiest boy I’ve ever seen, riding me like he was made for it,” Denki tries not to visibly react to the praise, but his breath hitches and he knows Monoma knows the moment those eyes sparkle like a young boy who’s found a new toy to play with.

Denki squawks when he’s suddenly tipped over from his seat in Monoma’s lap, back pressed against the sheets as Monoma looms over him.

Monoma—“

“Neito.”

“Neito, please,” Denki’s not sure what he’s pleading for but Neito does.

Denki’s legs find a leg hooked over his shoulder as he pushes his hips up, holding them tight in his hands; they feel big and warm and safe when they’re holding Denki’s like this.

“Ah!” He can feel it deep inside, thrusting in and out in abandonment and Denki’s world crumbles into just them. It’s heat and pressure, heady pleasure that makes his body tremble and his throat hoarse from screaming, that makes his skin damp and his hole drip with need. The sparks crackle and pop against his skin and it’s warmth he knows and twinges of pain that mesh into pleasure.

He doesn’t realise he’s crying until Neito cooes, “Darling, you asked for this. Didn’t you want me to ruin you?”

By then it’s too late to stop, overwhelmed by every touch, every push and pull, every firework bursting against his skin.

A finger digs into his dick and his vision whites out as the spark runs through his body. He cums hard, crying out and sobbing as he’s fucked through it, painfully sensitive and exhausted.

“I’m almost done, pretty, you can do it.” Denki nods dumbly, attempting to hold his thighs apart but too weak limbed to do much outside make Neito coo.

He feels like he’s short-circuited, his body going lax and head hazy, skin buzzing with energy. He gasps softly when Neito’s hips stutter and he cums, shivering at the feeling of hot cum covering insides. He whines when he pulls out, too empty after finally getting used to it.

“Oof.” Denki felt the heavy weight of Neito drop onto him. He wants to complain, but he actually finds it quite comforting. His arms draped loosely around his middle, nuzzling into the blondes hair. It was still damp, but not from the shower this time.

“Good?” Denki slurred eventually, fingers lazily tracing the ridges of his spine.

“Amazing. You were amazing, darling.” Neito groaned, pecking kisses over Denki’s neck. Denki giggled at the ticklish feeling.

His giggle hushed when Neito raises his head to kiss him properly, soft and lazy in a way that makes his head buzz pleasantly.

Denki doesn’t remember much after that, but he knows he fell asleep with Neito in his arms, cuddled up close. When he wakes up, it’s to Neito’s alarm.

The blond grunts and smacks the alarm, cuddling back into Denki’s arms without even opening his eyes.

“Neito, I gotta get ready for class.” He didn’t really want to go considering the ache between his legs, but he has training with Jirou is twenty minutes before classes even begins because they’re looking to team up in future.

“I hate mornings,” Neito grumbled but slowly released Denki in favour of grabbing his things for a quick shower. Which Denki would also need. Denki dressed quickly and went to the door.

“Hey?” Denki quirked a brow.

“What’s up?”

“If things don’t go well with Hitoshi, feel free to call me to fuck the heartbreak out of you.” He grins, wide and unashamed and Denki snorts.

“I’ll be sure to change your name to ‘Booty Call’ in my phone if it comes to that.” Denki blows a teasing kiss and closed the door behind him. He felt like a new man almost. A man who had finally done the sex.

He probably shouldn’t phrase it that way or Jirou would laugh at him.

“Denki?” Denki jumps in surprise, whipping around to Shinsou who looked like he had just woken up. “What are you doing here?”

“Oh! I was uh, asking Neito for some quick tips before I trained with Jirou. You know he’s always got a sneaky trick up his sleeve and I wanna really challenge her today!” Denki grinned widely to sell the story.

“Oh.” Shinsou looked back at Neito’s door. “Was there someone there with him?”

“Hm? No. Why?”

“I heard… a lot of something I didn’t want to last night so I figured I’d chew him out right after his new partner left, but I guess they left after I passed out.” Shinsou shrugged.

“I thought his room smelt rank. He looked pretty out of it too. Damn, did Neito finally get game? Crazy.” Denki laughed a little too loudly before checking his phone. “Aw man! I’m late! I’ll see you later, Shinsou!”

Denki ran off before he could embarrass himself further.

“…Since when did he use Neito’s first name?” Shinsou frowned slightly and shrugged before pounding on Neito’s door so he could chew him out for scarring him for life.
