Z/F- Zenitsu’s friend
“Hey! Knock it off, brat!”
Y/n laughs as Genya pushes her face away from his own, sending her stumbling back a couple of feet.
“Not until you give your girlfriend a kiss, you meanie!”
Y/n pounces on Genya again, this time locking her arms around his neck and hanging there like a child on monkey bars.
He gags and leans down to try to get her feet back on the ground, then, he turns around and flicks her forehead.
“Not right now!” he scolds. “We’re still in uniform!”
Y/n purses her lips in a pout, but resigns herself to walking next to Genya, gently humming a tune.
“Hey, Genya, what are we doing for Valentine’s Day, anyways?”
Genya glances at y/n, a faint blush on his cheeks.
Damnit.
He had hoped she wouldn’t bring it up.
“I dunno,” he says simply, rubbing his neck. “I figured we could just relax at home?”
Y/n smirks and intertwines her fingers with Genya’s.
“Relax, you say?” she purrs, giving Genya’s hand a gentle squeeze.
Genya’s face burns red at the implications y/n’s voice holds.
He and y/n have talked about sex before, and both of them have decided that they were ready to try some things out.
Y/n’s bold, shameless approach to it, however, was something Genya was not prepared for- especially not right now, in the middle of the sidewalk.
“Y-yeah,” Genya stammers, pretending to act innocent. “I thought we could watch that new horror movie, then make dinner…”
Y/n smiles and hugs Genya’s arm.
“It sounds perfect, Genya,” she says happily.
Genya gives a sigh of relief.
He really wants to romance y/n, it’s just that… he’s not very good at it.
He’d asked Sanemi about it, but Sanemi never had any good advice to offer.
It was never comforting to hear “How the fuck should I know?” or “Just go for it, dumbass!”.
He’s happy that y/n is comfortable with a quiet night in.
“Did you hear about Z/F and Zenitsu?” y/n suddenly asks, releasing Genya’s arm. “I heard she picked him up after school on her motorcycle! You think they’re finally going on a date?”
Genya scoffs.
“With the way he was acting today? Fat chance.”
The two continue to gossip for a while longer, walking through the streets of town like they did everyday after school.
Finally, they reach Sanemi and Genya’s house- a traditional looking home, made of dark wood panels and decorated with tiled roofs. A dozen potted plants sit outside, along with a couple of food bowls for the stray animals in the area.
“Is Nemi going out tonight?” y/n asks as she slides open the front door.
Genya shrugs, discarding his shoes and backpack.
“Dunno. He hasn’t told me much about Miss Urano. He gets pissed whenever I say her name.”
Genya’s thoughts briefly turn to his home economics teacher, Miss Urano. She and Sanemi had been in the early stages of romance for a while, but Sanemi was very defensive about his relationship with her.
“That’s just ‘cause he likes her,” y/n snickers. She picks up Genya’s backpack and carries it into the living room, knowing that Sanemi hates a disorderly home.
“We should probably get some work done before we watch the movie,” y/n continues, taking a seat at the coffee table. “I can help you with your math if you help me with history! I love Mr. Rengoku, but how am I supposed to memorize when the Kanagawa convention was?”
Genya grins and follows y/n over to the table.
“Sounds like a plan.”
“But first!” y/n shouts. She points to her lips, grinning.
Genya rolls his eyes, but leans down and gives her a gentle peck.
Y/n pulls away giggling.
“Okay! Let’s rock this bitch.”
***
“Hey, I’m going out.”
Genya glances up at his older brother, who stands next to the door, pulling on his blazer and adjusting his sleeves.
Genya pauses the movie to ask his brother where he’s going, but y/n beats him to the punch.
“Where are you going all dolled up?” y/n teases from next to Genya. “You have a hot date with you know who?”
Sanemi’s face immediately flushes red and he scowls.
“Keep it up, brat,” Sanemi snaps. “I’ll have you washing dishes for the next year!”
“Do you loveeeee herrrr?”
“Shut it!”
Genya slaps a hand over y/n’s mouth and smiles politely at his brother.
“Have a nice time, Nemi,” he chirps, waving goodbye.
Sanemi tuts and grabs his keys before waving two fingers at the teenagers on his couch.
“Don’t do anything stupid,” he warns before opening the door and stepping out.
Genya blushes and looks back to y/n, who grins at him.
“Yeah, Genya,” she says in a low, sultry voice. “Don’t do anything stupid.”
Genya’s face flushes even more red than before and he quickly presses play on the remote.
The screaming on the television continues, and y/n cuddles closer to Genya.
When the movie finally ends a few minutes later, the two briefly talk about what they’d just witnessed, coming to the conclusion that the movie was, in fact, shit.
“We need to follow that up with some good food,” y/n laughs, jumping off the couch and walking speedily into the kitchen. Genya is quick to follow, grabbing his phone to play some music as they work.
“What sounds good?” y/n asks, rummaging through the fridge. “Nemi hasn’t gone grocery shopping in a bit…”
Genya frowns and leans down to peek into the fridge as well.
He spots the key ingredients to quite a few sweets, but not much for an actual dinner.
“How about we make dessert first?” Genya suggests, pulling out a box of cream cheese. “I think we have all the ingredients to make a cheesecake…”
Y/n’s eyes light up and she shoots Genya an excited grin.
“I like the way you think, Genya!” she beams. She reaches into her pocket to pull out her phone, probably to look up a recipe.
A few moments later, Genya opens up his music app and starts playing some of his and y/n’s favorite nostalgic songs- predominately, 2000’s alternative and punk bands.
As he and y/n sing along quite badly to “Dear Maria”, they dance around and prepare the cheesecake batter. When y/n finally puts the cheesecake into the oven, Genya seizes her around her waist and begins to ferociously tickle her, music still blasting in the background.
Y/n shrieks and tries to fight him, but he’s far too big for her to put up much resistance.
Eventually, she decides that she’s had enough and grabs his shirt, tugging him down for a kiss.
The moment their lips lock, Genya can sense the passion and desperation behind the kiss.
After a few moments of heated kissing, Genya finds himself hiking y/n’s legs up around his waist, picking her up and placing her on the counter as they continue to kiss.
“Genya,” y/n murmurs as Genya begins to pepper her neck with kisses.
Genya pulls back and gives y/n a questioning look.
Y/n gives him a bright, mischievous smile in return.
“Let’s continue on the couch, hm?” she whispers, pecking the corner of Genya’s mouth.
Genya gulps and nods, letting y/n slide off the counter and take his hand in hers, leading him over to the couch.
Y/n turns around to Genya and presses his chest, pushing him down to the couch.
His face explodes into a brilliant red color as y/n sinks to the ground and positions herself between his open thighs.
“Y-Y/n?” Genya stammers, sitting up slightly.
Y/n tilts her head in a faux display of innocence.
“What?” she asks sweetly, her fingers drifting up to Genya’s waistband. “Do you not want to go any further, Genya?”
Genya shakes his head and y/n immediately retracts her hands.
“Alright!” she says cheerfully. “No worries! Are you still comfortable with kiss-”
“N-no!” Genya blurts, grabbing y/n’s wrists. “I meant… I want it, y/n. I want to go further.”
Y/n stares at Genya, her eyes wide as Paramore’s “Misery Business” blasts in the background.
Finally, y/n smiles warmly and lowers her hands back down to Genya’s pants.
“Well, then…” Y/n unbuckles Genya’s belt and begins to tug down his pants. “Let’s do it.”
Genya lifts his hips to better assist y/n’s efforts, then, blushing, he lets her slide down his pants completely off to reveal his boxers.
Completely mortified, Genya realizes that he already has an impressive erection.
Y/n grins upon catching sight of this and runs her fingers across his bulge. Genya’s breath catches in his throat and he struggles not to kick his hips up at the sudden contact.
“Damn, Genya,” y/n teases. “I had no idea you were packing.”
“Sh-shut up,” Genya replies in embarrassment.
He begins to imagine y/n’s lips wrapped around his cock, steadily sucking and stroking as he whines and pants.
He feels dirty for letting his mind think of y/n in such a compromising position.
She’s not actually gonna do it, Genya keeps thinking to himself. There’s no way.
Y/n pulls down Genya’s boxers and his cock springs forward. Genya’s entire body flushes red.
Y/n gently nuzzles the side of her cheek against it, looking up at Genya with her beautiful golden brown eyes.
“Do you want me to blow you, Genya?” she asks in a low, seductive voice.
Genya gulps and feels himself begin to shake.
“I… I mean, if you want to…”
Y/n smiles sweetly and gives Genya’s cock a few tentative kitten licks.
Genya shudders at the feeling of her tongue against his sensitive flesh, and without a moment of warning, y/n’s mouth suddenly sinks down on Genya’s length.
“Sh-shit, y/n!” Genya gasps, his large hand flying to the base of y/n’s skull.
Y/n chuckles lightly, sending vibrations throughout Genya’s body.
Y/n’s head begins to bob up and down as she sucks steadfastly on Genya’s cock. She can’t possibly fit the whole thing into her mouth, so she strokes the lower part of his cock with her hands.
Genya’s hips tense and twitch as he tries to prevent himself from kicking upwards. Y/n suddenly takes Genya even deeper than before, letting out a soft moan as she does so, and Genya grits his teeth.
He doesn’t want to make too much noise, afraid that it might turn y/n off, but Christ is it hard to keep quiet.
A moment later, as y/n once again begins to focus on his head, Genya snaps.
“F-fuck, y/n,” he groans. “So fucking good.”
Y/n’s hand drops down to his balls, cupping and stroking them gently as her lips encircle his head.
Genya gives a high pitched whine, then gasps at the sound that just left his mouth. Y/n giggles once more and releases Genya with a soft pop.
She looks up at Genya through half lidded eyes, absolutely drunk off of lust. A mixture of saliva and precum drips down her chin, but she pays it no mind.
“You enjoying yourself, big boy?” she teases. Genya, unable to properly form a sentence, shudders and nods.
Y/n rises from her kneeling position and crawls onto Genya’s lap. His face burns red as he feels his cock press against her clothed cunt, hidden by her short skirt.
Y/n cups Genya’s face and presses her lips against his hungrily. Genya’s hands wrap around her petite waist and pull her closer to his body. Y/n suddenly pulls away and places her hands on Genya’s chest.
“Do you want to go all the way?” she whispers, gazing directly into Genya’s eyes.
Genya feels his cock twitch and he exhales sharply.
“Yes,” he murmurs with a light laugh. “Fuck, yes.”
Y/n grins and wipes her mouth.
“You have a condom?” she asks.
Genya nods.
“I- uh- yeah, in my room,” Genya stamers. “I’ll go get one.”
Y/n smiles and briefly kisses Genya before sliding off of his lap.
Genya hikes up his boxers and half jumps off of the couch, heading down the hall and into his bedroom.
Weeks ago, when Genya had first asked Sanemi about sex, Sanemi had given Genya a lecture about being safe. He’d immediately forced Genya to buy condoms, and made Genya promise to tell him when he had sex with a girl (“Or a guy, or a person, or whatever the fuck”).
Genya hadn’t thought he’d be needing a condom so soon, but… here he is, rummaging through his bedside drawer as his girlfriend waits in the other-
“Eager, are we?”
Genya jumps slightly and turns his head to see y/n standing in the doorway. She’s shed her skirt and begun to unbutton her shirt, revealing her matching black undergarments.
Genya’s face flushes red and he turns his attention back to the drawer. Finally, he finds the pack of condoms and tears one off, holding it up triumphantly.
Y/n grins and crawls on to Genya’s bed, continuing to strip her clothing away and carelessly fling it across the room.
Genya pulls his own clothes off and rolls on the condom, exactly as he’d been shown (during a rather awkward encounter involving a banana and an extremely red Sanemi), then turns around to face y/n. She immediately pulls him in for a kiss, slipping her tongue into his mouth with ease and gently pulling him down so that he is situated on top of her.
Genya cages y/n with his hulking frame, continuing to kiss her passionately as his cock brushes against her inner thigh.
Genya affectionately nips at y/n’s neck and she sighs, letting her hands wander down to his hips. She presses him a bit closer to her pelvis and Genya feels his entire lower body tingle in anticipation.
“Genya,” y/n whines, her hand drifting down her own body. “Aren’t you gonna prep me a bit better?”
Genya watches in shock as y/n lowers her hand, pulls down her underwear, and begins to rub gentle circles around what, he assumes, is her clit.
He and y/n had talked about their experiences touching themselves before, but he never would’ve thought he’d be seeing it up close and personal.
Y/n is just so fucking beautiful, in every way.
Genya presses a firm, reassuring kiss to y/n’s lips before shrinking back and grabbing her thighs.
“Genya?”
Y/n yelps as Genya suddenly drags her closer to him. He gives a good natured laugh, then begins to gently kiss y/n’s thighs.
“Don’t worry, y/n,” he muses, strangely confident. “You took care of me, now… let me take care of you.”
Y/n blushes bright red and covers her face with her hands, laughing.
“Where did this guy come from?” she teases.
Genya rolls his eyes, grinning. He glances back down at y/n’s cunt. It’s a lot different than a dick, for sure…
Genya leans forward and softly blows air against y/n’s clit, causing her to jolt up.
“Do that again and I’ll sock you,” she warns. Genya laughs and licks a stripe up her folds to subdue the fiery young woman.
It works like a charm.
Y/n shivers and relaxes her body, opening the floor to let Genya do as he pleases.
Genya decides to experiment with the area y/n had been touching earlier.
He gives the area a couple of soft licks before letting his tongue slip in between her folds. Y/n’s legs immediately begin to shake, unused to the attention her cunt is now receiving.
“Fuck, you’re so cute,” Genya chuckles.
Y/n laughs in return, then knocks her knee against Genya’s head.
He takes this as a sign to continue.
Genya begins to tease y/n’s clit with quick flicks, then, he presses his tongue flat and moves it in firm circles.
Y/n cries out in pleasure and jerks her hips upwards. Genya squeezes her thighs tighter and forces them further apart, hungrily lapping at her arousal.
“G-Genya,” y/n gasps. “Keep going. Right there!”
Genya continues to focus on y/n’s clit, sucking and licking in rhythmic patterns.
Y/n swears and squeezes her thighs around Genya’s head, panting and moaning softly.
Genya absolutely loves to watch her fall apart like this- her normally fiery personality giving way to a more pliable, desperate side. It sends blood rushing to his lower body, making his cock throb with anticipation.
“Babe, I’m- I’m close.”
Genya pulls away and y/n sits up, grinning.
“Let’s move on to the next part?” she asks, cupping Genya’s face.
Genya nods and tackles her in a kiss, once again repositioning himself so that he’s on top of her.
Y/n reaches down to Genya’s cock and gently strokes it, then guides Genya down to her sopping wet hole.
Genya drags his cock up and down her folds to collect some slick, then gives y/n a nervous but loving smile.
“Are you ready, lovely?” Genya asks, using a rarely used nickname.
Y/n grins and nods, lifting her hips slightly to better accommodate Genya’s impressive size.
He slowly presses into her, gasping at how warm and tight her walls are around him. Y/n’s cunt sucks in his cock inch by inch until finally, Genya bottoms out inside of her.
As Genya struggles to not immediately begin thrusting, y/n cups his face once more and grins.
“I’m surprised you haven’t passed out yet,” she teases.
Genya laughs and nuzzles his face against her hand.
“Trust me, y/n, I’m wide awake.”
Genya slowly pulls out of y/n, then sheathes himself back in.
Y/n hums a tune of approval, signaling that Genya can continue.
Genya repeats the action, rolling his hip against hers, and y/n gives a low moan.
“How’s it feel, Genya?” she breathes, her hands on his shaky arms.
Genya chuckles and continues to thrust into her at a slow pace.
“Fucking amazing,” he responds, placing a loving kiss against y/n’s lips.
Y/n grins as Genya leans lower down on her body and begins to increase the speed and power of his thrusts.
“F-fuck!” Genya swears, hips working quickly against y/n’s. “So ‘fuckin tight…”
Y/n moans and squeezes Genya’s biceps. Her hands don’t come close to wrapping all the way around them, and her nails are beginning to dig in, but Genya relishes the feeling anyways.
“‘M close, Genya!” y/n whines, her hips snapping against his. “I’m so close!”
Genya’s face flushes red and he continues the rate of his thrusting, bringing up a hand to rub at y/n’s clit.
“It’s alright, y/n,” Genya whispers, his lips grazing y/n’s ear. “I’ve got you. Come for me.”
A moment later, y/n cries out and Genya feels her walls tighten around his cock. As y/n lets out a string of curses, Genya continues to thrust into her body, chasing his own high.
“Fuck, Genya!” y/n moans. “Fuck, fuck!”
Genya’s hips stutter and his pace falters, and seconds later, he’s hit with a wave of pleasure. He lets out a raspy groan and his thrusting slowly comes to a halt.
He looks down at y/n, who grins at him with a thoroughly exhausted expression on her face.
He returns her smile, letting out a breathy laugh before pulling out of her and getting off of her body to dispose of the condom.
When he turns back around, y/n is sitting up in bed, smiling like she’d just won some grand prize.
“C’mere, Genya,” she murmurs, opening her arms.
Genya doesn’t offer any objections, hopping back on the bed to cuddle up to his girlfriend.
The two lay down, limbs tangled together and foreheads pressed against one another.
“That was amazing, y/n,” Genya finally says, chuckling slightly.
Y/n grins and snuggles even closer to Genya’s chest.
“Yeah?” she asks. “We’ll have to do it again, sometime.”
Genya laughs and squeezes his partner tightly, placing his chin on top of her head.
“I love you, y/n.”
“And I love you, Genya.”
The two lay in comfortable silence for a few more moments before Genya’s nose tickles. He frowns and sits up to smell something burning.
Slowly, the gears begin to turn in his head and he cusses, jumping out of bed and pulling on his boxers.
“You didn’t start a timer!” Genya shouts.
Y/n leaps out of bed after him and puts on her own underwear, rushing into the kitchen to find the oven filled with smoke.
“Shit!” she swears, grabbing the baking gloves and pulling open the oven. As smoke floods into the room, she half throws the eviscerated cheesecake onto the counter.
“You’re gonna set off the fire alarm, dumbass!”
“It’s not on fire!”
“Yeah, but the smoke!-”
BEEP! BEEP! BEEP!
Genya groans in frustration and grabs a towel, whipping it through the air in an attempt to get the smoke to dissipate.
Y/n joins the makeshift fire brigade with a tea towel.
Within a couple of minutes, due to the valiant efforts of both teens, the smoke alarm stops going off.
Genya and y/n take one look at eachother, dressed in only their undergarments and winded from the sudden exercise, then burst into laughter.
“You- you look like a fuckin mess!” Genya wheezes.
Y/n cackles and punches Genya’s shoulder.
“Like you look much better!” she retorts, still out of breath. “You look like a wild animal with that hair of yours!”
Genya leans down so that y/n can tousle his thick black hair, then his laughter slowly crawls to an end.
Y/n stares at him, smiling, still holding the tea towel in her hand.
“I ‘fuckin love you, Genya,” y/n breathes, hugging him around his waist and pressing her cheek against his chest.
Genya squeezes y/n tightly and rests his chin on her head.
“I love you too, y/n. Now… let’s just order some ‘fuckin pizza.”
