Work Text:

You've been horny all night.

Your boyfriend, Itadori Yuji, is wearing a simple plain white dress shirt which he folded up right below his elbows. He has two buttons undone and the shirt is tucked in black dress pants, his long legs causing for his ankles to show right above the black boat shoes he has on his feet.

He finished the look with a white silver watch on his left wrsit. Honestly? You could feel your cunt already dripping just by the way your boyfriend looked while the two of you were still at the apartment.

As the group; Nobara, Gojo, Nanami and Yuji sang happy birthday for Megumi, you're busy rubbing your thighs together, proving for the action to be a bit more difficult than it actually is when you're seated.

Megumi blows his candles and everyone cheers, clapping their hands as they begin to dig into the food. You try distracting yourself, scooping in a few scoops of food on your plate but it is all for naught when Yuji leans over, giving you a chance to get a whiff of his cologne.

A strong strawberry scent with a little bit of sweet vanilla and a hint of bold wood. The scent doesn't smell like it goes everywhere at all- it all smells so good together. Yuji uses his chopsticks to place some strips of beef on your food, your gaze immediately on his forearm- veins feintly protruding from under his light skin. The silver around his wrist doesn't help at all and it makes you feel as if you are this horny teenager again.

"Eat up." Yuji smiles, his eyes smiling with him. You force your lips to stretch, sending him a big smile back before eating your food, deciding to forget all about your thoughts by stuffing food in your mouth.

It works.

Well, more or less. You haven't had a single dirty thought about your boyfriend ever since you began eating, and now Nobara is currently singing her heart off as Gojo and the birthday boy himself are dozing side by side on the end of the couch. Nanami is busying himself by sipping on his drink, a smile faint on his lips as he watches and listens to Nobara sing, looking like how a proud father would.

Your boyfriend, on the other hand, doesn't look too good.

"You okay, babe?" You ask, leaning in to squeeze his forearm softly. He snaps out what seems to be in a caging gaze he was in, looking at you. Yuji smiles, hand fluing on yours to give it a good, reassuring squeeze. "I'm good, baby. Just a little tired, I guess."

You furrow your brows, definitely not buying his lies. "Just tell me. The faster you tell me the faster we can solve the problem." You say, crossing your arms over your chest.
Yuji's eyes slowly and uncontrollably begin traveling down your chest, gaze glossing over your evident cleavage, moving again even much lower, his eyes taking note of how the black dress you're wearing is hugging every curve on your body perfectly.

Yuji leans in, his strong cologne scent causing the butterflies in your stomsch to go insane. "That dress has been driving me crazy the whole night." Your boyfriend's hot breath fans over the shell of your ear, casuing goosebumps to rise all over your body. "Take it off for me, please?"

You breath in a deep and shaky breath, closing your eyes to try and convince yourself not to strip naked in front of your friends and teachers right here on the spot. You stand up abruptly, catching Nanami's attention.

"We gotta go, Yuji has a really bad stomach ache." The corners of your mouth pull down into a fake frown which Nanami buys, nodding his head and waving the both of you off. You take Yuji's hand and pull him out of the Kareoke room, your heels loud as you stomp your way out of the building and to the parking lot.

As you find your car, you pull the front seat's door open only for it to be closed shut again by your boufriend. Yuji pulls you closer by your waist, making you can feel how hard he is inside his pants.

"We're not doing it here."

"My car's windows are tinted." He bites on your ear.

You keep telling yourself not to do it, to just wait until the both of you gets home but Itadori jr. seems to be having other plans for tonight. You sigh, walking over to the back door and pulling it open. As soon as you bend over to get in, Yuji pushes you and slams the door behind him.

The cold winter nights of Japan has the interior of the car all cool and comfortable. Yuji spins you around by your waist, running both of his hands on either sides of your waist. He breathes out deeply, eyes scanning hungrily over your form. His hands begin to make their way down your thighs, he leans in to give you a soft peck on the lips. Yuji looks into your eyes at first before leaning back in to envelope you into a deep kiss, his tongue skillfully brushing and sliding against yours as he sucks on it softly. His breathing his ragged as he feels your body all over, your legs instinctively opening and moving up his hips. Yuji presses his hard member against your clothed cunt, grinding on it for some kind of friction before pulling away when he feels just how soaked you are down there.

He reaches a hand under your dress, pressing two fingers on your wet cunt making you mewl. You've been holding it in for too long and now you're just very sensitive. The corner of his mouth twitches up, "Have you been wet for me the entire night, baby?"

You don't trust your voice, you can't. You know it'll sound needier than you actually are, you know it'll set Yuji off to start teasing you, so you nod your head, your face contorting as you feel him slip a finger between your folds.

He leans forward, hot breath fanning over the sensitive skin on the side of your neck. Yuji's warm tongue runs up the skin once, twice- he's adding another digit into your wet hole and you almost cum at the spot when he nibbles on your soft skin.

"I'll take very good care of you tonight." He presses his soft lips on the nibbled part of the skin, slowly trailing kisses up to your cheek and finally back onto your lips.

You couldn't think straight- your head was full of the boy. You absolutely loved about him; his strawberry pink hair, when he smiles with his eyes, how he can never go through a day without cuddling you at least once, how he does his best to give you anything you want, how he's one of your biggest inspirations in life. This boy- no, this man is someone you can imagine waiting for you at the end of the isle, hot tears streaming down his face as he waits for you at the end of the path, looking at you as if you were the most beautiful woman he's ever laid eyes on- yes, even more beautiful than Jennifer Laurence.

Aoi would be right beside him, rubbing a hand on his back as he tries to soothe his best friend's sobs.

You snap out of your daze when you notice your boyfriend looking deeply into your eyes, a soft blush caressing his cheeks as he studies your face ever so lovingly. "I love you." You tell him.

His blush darkens as he leans into you, pressing his lips once again on yours. "I love you too." You feel the head of his cock press against your entrance for a bit before entering you completely.

You let out a soft whine, arching your back as your lips are trapped between your teeth. Your eyes roll back at the feeling of your boyfriend slowly pushing his entire length inside you, getting you feeling so full of him. "Yuji..." Your voice sounds so lewd, so needy and whiny for him that the sound of it makes you blush. You feel him stop moving once he's inside you fully, and at first you think he's letting you adjust to his size. That is, until he pulls his head back and your gaze falls onto the black lines all over his face. The soft look that once inherited your boyfriend's face is now replaced by a smug, cocky one. He has a smirk on that tells you to push him off and quickly get out of the car- but why don't you?

Instead, you feel yourself clenching around him even more. The look on his face has you dripping wet, your nipples hardening underneath your dress and the butterflies in your stomach going crazy as ever.

"Can't believe that little boy would keep you all to himself." His voice isn't Yuji's- no. It's much deeper, darker, more dangerous. He looks down at your apalled expression, his smirk growing even bigger. He leans over, pushing your legs up to your chest and forcing you down into a mating press. "What's my name, princess?"

You can feel your heart beating rapidly against your chest, your breathing shaky and your head clouded. Without even thinking about it, your mouth moves on their own and out comes your whimpering voice.

"Sukuna."

The curse pulls away with a wide grin, pulling his hips out before thrusting his cock inside you again, the tip of his cock hitting the same spot as it did before. Sukuna's hips are relentlessly thrusting inside you, abusing your needy hole as you moan loudly for more.

His hand finds its way to your boob and you feel something hot and wet lap itself over your hardened nipple. You look down to see the mouth on his hand grinning cockily like him. It wraps itself around your nipple, sucking on the bud and biting on it softly making your eyes rolls back to your head.

You feel something coil up inside your stomach, your mouth opening as you feel yourself slowly reach your high. "I-I'm so, fucking, clo-" Sukuna thrusts his hips hardly once, causing your toes to curl and your body to shake as you move your hips to ride out your orgasm.

Heavy breaths fill the car as your legs grow limp on either side of his body and your eyelids become heavier.

"The fuck do you think you're doing?" Sukuna squeezes your cheeks, making your eyelids lift open. He hooks his arm around your back, pulling you along with him as he sits up.

Your eyes widen and back arches when you feel electricity run up your spine. Sukuna lifts a brow, his hands on either side of your hips, preventing you from lifting them.

"Too full!" You whimper out, tears forming on the corners of your eyes as you swallow a large lump down your throat.

"Hah?" He tilts his head to the side, "But I haven't even came yet." You feel him roll his hips once, but it was all it took to have you digging your nails on his shoulders. "I'll pull out when I cum. But for now," He lowers his head to take your nipple by his mouth, his fingers pinching and playing with the other one. ",focus on making me feel good, princess."

Your eyes clench shut asbyou focus on the feeling of his hard member inside your dripping cunt. You move your hips once, you feel goosebumps all over your body. You move your hips a second time and you're wanting to feel that same friction again. You move your hips a third and you're letting your desires take over.

You hump on Sukuna's cock sloppily and roughly, the car is shaking. Sukuna let's out soft groans and moans, the constant "love feeling your cunt around my cock like this" whispered and growled into your ear. His eyes travel down to your chest, eyes gleaming when he sees your boobs bouncing in sync with everytime you hump on him.

When he looks back at you, all his other sense go numb. The sight of you with your tongue out your mouth, you drool dripping down your tongue, your face flushed and your eyes crossed together at the feeling of it being so good has him gripping on your hips tightly. "You're a fucking slut, aren't ya?" He begins thrusting himself inside you and you moan loudly, your toes curling at the feeling of his sac slapping against your skin. "Aren't ya?!" He yells and all you could do is whimper as you nod your head. He's fucking you so dumb you couldn't form coherent words.

He rolls his hips as he thrusts them, making sure you feel every single inch of him inside you. Your moans are in sync with his thrusts, feeling your breath being knocked out of your system with every thrust the curse does.

Your hand flies up your mouth, trying to surpress the loud moans that keep slipping out of your lips but Sukuna wraps his hand around your wrist, pulling your hand away.

"Scream for me, come on princess. Let him know who's fucking you so good right now." His voice is low and deep, it drives you to the edge, almost pushing you off. "Wh-who? Who's him?" You ask, forcing your eyes to open as you look down at Sukuna- your eyebrows raise in surprise at the sight of the black lines on your boyfriend's face gone.

Yuji looks up at you with eyes holding such lust. He has a straight expression on as he looks into your eyes, kind of hypnotising you as he thrusts into you, leading the both of you to your highs.

"Wh-what happened to Sukuna-"

"Why are you looking for him." Yuji's voice is covered in coldness. He combs his fingers on the back of your head and throughyour hair, curling them into a fist as he pulls on your hair. "He's not the one fucking you right now, I am." His thrusts start becoming more aggressive, hinting at you that he's already close.

"You'll cum around my cock a second time and you'll be moaning my name out as loud as you can. Got it?" Yuji growls onto your neck. His other hand grabs onto your hip and begins thrusting into you faster than before. You feel something snap inside you, your orgasm causing your toes to curl and your fingernails to be dug onto your boyfriend's skin. "Y-Yuji!" Your hips shake as you begin rolling them around, riding out your orgasm.

"That's not my name right now, princess." You look back down only to feel your heart drop at the sight of the black lines all over his face. "S-S-Sukuna! Sukuna!" You moan out, your chest rising and falling exceptionally. You hear him chuckle before feeling him pull out, shooting his hot seed all over your naked cunt.

You look back up, checking to see who's who right now. You smile when you see it's your boyfriend. You press your forehead on his shoulder as you try to calm yourself down. You feel his arms wrap themselves around you as the two of you bask in each other's presence.

"You gotta stop doing that, it fucks up with my brain." You mumble onto his chest which only leaves you with a lighthearted chuckle. "But Sukuna says he doesn't want to be left out."

"Whatever, Sukuna can go fuck off." You mumble sleepily.

"Why don't you fuck me yourself, princess?" A deeper and much darker voice speaks up and you curse yourself mentally.
