switch

summary: you and yuji have been together for three years now, but on your anniversary night, you allow your own demons to come to the surface. pairing: ryomen sukuna x female!reader (itadori yuji x female!reader, too, i guess?) | aged up characters word count: 3.5k warning & content: cheating?? (is it cheating if it's technically the same body?), unprotected sex, creampie, slight dacryphillia, vaginal fingering, blackmail, reader is kind of an asshole? (can you blame her tho, sukuna is such a daddy ugh), bit of overstimulation, slight dumbification (if you squint)

a/n: i'm back, and i can tell my writing skill is getting rusty. i took a break and it's obvious with this fic, but i need to get my head back in the game. it is what it is.

Yuji was a great boyfriend. In all honesty, he was every woman and man's dream — funny, charming, attentive and, most importantly, caring. He cared about you so much that he always made sure to control his own personal demon. You knew about Sukuna, Yuji told you after a few dates, and you were well versed in Jujutsu Sorcery, enough to know that he was not someone you could mess with. But you didn't want to give up on Yuji, and stuck with him through thick and thin. After almost three years of the beautiful and fun relationship you two had, he asked you to move in with him since you were both adults now, and you gladly accepted, because after so much time, you came to love him, despite seeing Sukuna's outbursts during fights. That thing, that monster, was beyond terrifying, but you trusted Yuji with all your heart, and that was all that mattered.

Or maybe you were unhinged, maybe you wanted Sukuna to come to the surface. Maybe, deep down in your heart, you fell in love with the switch, with the raging, brutal frenzies that you happened to witness on the rare occasions when Yuji couldn’t control the King of Curses. Maybe you weren’t meant to be a Jujutsu Sorcerer, because, as opposed to your optimistic and good-natured boyfriend, you never hesitate to kill – human or curse. Sometimes it felt as if your curiosity surpassed your love for Yuji, and that was a horrendous thought. Surely, that can’t be the real you, right?

Today is your three-year anniversary, and naturally, you want to surprise your boyfriend, so when you come home from a mission, you stop by his favourite ramen restaurant, picking up something to eat, maybe even some dessert. You tiptoe inside when you notice Yuji napping on the couch, and after silently setting up the table, careful not to wake him up, you quickly change into something... nicer. Yuji doesn't really enjoy it when you show some skin, which sucks because you want him to show you off. Nevertheless, you respect him, but tonight is special, surely it wouldn't hurt if you wear a shorter skirt. And a low-cut blouse. And heels. Fuck it, you think, adding a pair of thigh high socks as well, maybe that would rile him up. As much as you loved him, Yuji was too gentle. You liked that about him, truly, but sometimes you just need him to give you a good fuck, which was impossible, no matter how much you begged him to do it. You watch your reflection in the mirror from head to toe, proud of your skimpy outfit, but you can't help but wonder if he might be upset at your choice of attire. Even if he prefers it when you're dressed in pastels, that's not you, the real you. "You look good enough to eat." Yuji's voice breaks your trance and you turn on your heels to look at him. He stands in the doorway of the bedroom, arms folded across his chest, but there's a strange aura around him, and you can't exactly see his face through the dim lights. "You like it?" Your ears perk up, happy that he's not bothered by the clothes. "I do. You should dress like that more often." He sneers, stepping closer to you. "Alright, what kind of prank are you pulling now, Yuji? You never liked these kinds of clothes." You lower your head, your luscious lips turning into a pout. His calloused fingertips grip your chin, turning your head to face the mirror, and that's when you see the black markings on his face. Fear paralyses your entire body, eyes widening in panic and anxiety. "He might not like them, but I do." His voice is lower than Yuji's, calm yet obscenely dangerous. "I- you-" The words get caught in your throat, and you can't take your eyes off of his reflection. You know for a fact there's absolutely nothing you can do to defend yourself from Sukuna without hurting Yuji, and that thought makes you feel incredibly small and downright pathetic. "Little lamb, do you have any idea how hard it's been for me to watch this ungrateful brat take you for granted?" His hand is still leaving imprints on your chin and cheek, the other travelling down your back. "To watch you lose yourself for him, of all people?" "You don't know me!" Lips open without a thought, and you regret every syllable that came out of your mouth. "Oh, but I do." Yuji, no, Sukuna sneers, that same hand that was once on your back is now on your abdomen, painstakingly slowly creeping under your blouse. "Everything he sees, I see. Everything he smells, I smell. What he hears, I hear. But I just couldn't touch what's mine. Until now." You feel him pinching your nipple, and you're ashamed to admit how good his skin feels against yours, his hot breath fanning over your nape. "'M not yours." You grit your teeth, manicured fingernails digging into the plush of your thighs to keep your composure. "There's one thing I can smell that he can't. Wanna know what that is, sweet dove?" He whispers in your ear, and it's dotting your skin with goosebumps. "Enlighten me." "Your arousal." "You're bluffing." Is all you manage to say before Sukuna spins you around, pinning you against the mirror. "Let's see, shall we? I bet you're dripping," he shoves one of your legs to the side with his knee, and you don't stop him, "I bet you you've fantasised about this, late at night, when this brat can't please you. He's well endowed, though, it's a shame he can't use his dick." "S-stop it, please. I love him." "Pardon me if I doubt that." "Please, sir..." Sir? How should you call him? Demon? Cursed spirit? Monster? "How about master?" Sukuna barks back, as if reading your mind sarcasm dripping

down his tongue. You can't stifle a moan when his teeth sink in the crook of your neck, and you know damn well that you want this, and that every word he uttered so far was correct. You have thought about Yuji switching with Sukuna, wondered how he would fuck you, make you chant his name, but you never told your boyfriend, you couldn't. It's sinful, disgraceful and disgusting. Instinctively, you grind up his thigh, tears of shame and lust pooling at your eyes when you slowly give in to the temptation. He's already bruised your skin, one hand toying with your tits, the other lifting your skirt up. It's too late to fight him, because you never wanted to fight him in the first place. You deepest, darkest wish is finally coming to life. "That's better." Sukuna licks his lips, and your half-lidded, glossy eyes land on his tongue. "Please, m-may I kiss you?" Eyes dart away, cheeks burning with desire and embarrassment. "How polite of you to ask." He coos at you mockingly, his face inching closer to yours before absolutely crushing your lips under his. You don't hesitate to partly open your mouth, allowing his tongue to slip between your lips. Fuck, he kisses you so good that your knees give in, and all you can think is that if he's such a good kisser, he's definitely going to fuck you dumb. And you want that more than anything. When he pulls away, you lick your lips, still tasting him on your tongue, and he tastes so much better than Yuji — sweet and addictive. "I really wanted to take my time with you, after all, I waited three long years for this. But you're such an eager little slut, aren't you?" "I'm n-not a slut-" You try to protest, but you can't fool him, especially not when he's pushing your panties to the side, fingers grazing over your slit. "You are a slut. You merely buried that side of you for a pathetic little boy who can't handle a real woman." Sukuna's index finger gently brushes against your clit, enough to have you weak and needy. "Don't worry, Y/N, you don't have to hide from me. You can show me what you really want." It hurts to know that Yuji probably sees and hears everything, that he will probably break up with you after this, but you're too far gone to care about his feelings when finally someone is paying attention to yours. Your hand travels up his thigh, palming his already hard cock, and the way he groans, throwing his head back is satisfying enough for you. It hurts to think that Yuji never appreciates this side of you, and it's more painful when you consider this to be cheating — it's still his body, technically, but it's not your loving boyfriend, and you're perfectly fine with that. He slips a finger between your folds, a quiet moan escaping your lips, and Sukuna knows you won't dare say no to him, or try to reason with him. He adds another finger, but he absolutely does not move them an inch, instead you automatically fuck yourself on his hand, gripping one of his shoulders for support. "That's a good whore." Sukuna praises you, tongue lapping at your collarbone, making you delirious with lust. "You want my cock? Want me to fuck your aching cunt?" It's impossible to refuse his proposition, instead you buck your hips, your fingers gripping his t-shirt and you know you might tear it if you keep this up. "Yes..." You answer him, voice soft and quiet. "Yes what?" "P-please... Yes, please!" "Much better. Get on the bed." Sukuna commands and you obey, skirt dangerously hiked up. You proceed to take it off, but he slaps your hands away, too impatient for such formalities. He did wait a long time for this, you understand that, and so you lay on your back, blouse unbuttoned, panties on the floor and legs wide open for him to take you. Oh, and he adores this sight, how you willingly give yourself to him, your dainty fingers spreading your juices around your cunt, eager to be filled. In those three years of being with Yuji, you got used to his cock, but seeing it now seems like it's the first time. Precum leaks from the blushing tip and your mouth begins to water just by looking at him, and

this pleases Sukuna greatly. "Tell me what you want." He climbs on top of you, hands resting next to you as your fingernails graze over his chest. "I don't wanna say it..." You avert your gaze, a crumb of dignity left in you because you know Yuji hears everything. "Oh, you don't?" He quirks a brow, brown irises bearing a hint of red. "Then you won't mind me killing the brat." This garners your attention, and you feel stupid because of course he would blackmail you. Do you care? No. Do you want Yuji to think you care? Yes. "Please don't hurt him." You look back at Sukuna, tears pricking your eyes. "Why shouldn't I? We both know he doesn't deserve you." "You're wrong, I love-" "This isn't about you loving him, it's about you renouncing your true nature." His hand finds its way on your neck, fingers wrapping around it. "How many times have you begged him to choke you and he refused? How many times did you ask him to fuck you harder and he said no? You're a filthy slut, Y/N, and it's time you got what you deserve." The lack of air has your pussy clenching around nothing, and you hate him so much for being right. Yuji could never give you what you want, but Sukuna can, and it's an opportunity you can't pass. "Now, I'll say this one last time — tell me what you want." He releases the grip on your neck. "Y-you! I want you to fuck me, please, fuck me good, make me yours!" The tears that roll down your cheeks ruin your makeup, mascara mixed with eyeshadow smeared under your eyes. The tip of his cock pushes past your folds, and inch by inch he bottoms out. It feels bigger than before, stretching you open in a beautiful blend of pain and pleasure, your lips forming an O as your eyes roll back. "He doesn't deserve your tears. But I do. Cry for me." Sukuna sneers, his broad frame hovering above you and you feel so small and vulnerable. Yet again you obey, allowing more salty droplets to run down your face as you wrap your legs around his waist, feeling him go deeper. "Fuck, 's big! Oh, god-" Sukuna's palm meets your cheek, a sharp, stinging pain bringing your eyes on him. "Focus, whore. Not god, not the brat, me." He grunts, hips rocking back and forth harder and faster. "Who do you belong to?" You don't want to say it, what would Yuji think of you? He's probably already disgusted, contemplating breaking up with you once he regains control of his body. Another slap pulls you out of your thoughts and you buck your hips against his. "Answer me." "I b-belong to you! You!" "That's right, you're mine. Don't worry your pretty head, little lamb, Yuji won't be coming back any time soon." He grunts with every thrust, and his reassurance is somewhat comforting, because, god, he fucks you so good, you would kill for another opportunity like this. His teeth sink into your shoulder, fingers bruising your skin and you're delighted that he's marking you. All that matters is that you're his, chanting his name over and over again, praying to your new god, and Sukuna is beyond pleased with his work of art. When he pulls out of you, you almost cry, because it feels like a part of you is missing, but he's a merciful god, he won't let his newly devoted subject famished. Flipping you over as if you're made of feathers, he thrusts back into your aching cunt, and you yelp at the feeling of being overpowered by him. Sukuna's stamina is off the charts, because while your legs begin to feel numb, he's fucking into you with such force and intensity that the damn bed slides on the floor. It's raw, the way he's defiling your cunt, and it's sending your brain into overdrive. Your spongy walls clench around his cock, and while he doesn't say anything, the simple fact that he's going deeper and harder makes you feel special. Squirming and thrashing under him, you're desperate for some form of validation, and so you lift your ass up, pushing it back against his hips with a delightful moan escaping your lips. Sukuna takes notice of your sudden change of posture, and the way you curve your spine to try and get a look at him is adorable. "You want something,

pet?" He barely spares you a glance, and his indifference makes your pussy flutter. Your incoherent sentence almost makes him laugh, words such as good and please distinguishable between the other stutters. "Use your fucking words." A slap over your firm ass makes you yelp and jolt up. "A-am I good enough f-for you?" The question takes him by surprise, but he doesn't stop to think. Instead, he digs his sharp talons into the plush of your hips, overjoyed by your eagerness to please him. "You could do better." Sukuna teases you, but you take it personally, sadness and determination coiling inside of your heart. By this point, you don't even remember your boyfriend's name, too high on pleasure to even care. "'M sorry! P-please, I wanna be good!" You throw your head back and he wraps an arm around your neck, pressing his chest against your back. "If you wanna make me happy, you best forget about Itadori." "W-who?" "Your– never mind." Sharp canines flashed in his smirk, Sukuna tilts your head enough for you to catch a glimpse of his eyes. They're dark and vicious, and any sane person would be repulsed by them, but not you. No, you drown in them, completely absorbed by the hatred hiding behind them. The more you stare into his orbs, the closer you are to your climax. And he knows it. "Fuck fuck fuck!" "That's right, little lamb, let go of all that is moral and human." "Don't stop- oh, god, please don't s-stop!" In your frenzy, in his frantic pace, Sukuna's close, too. It would have taken any other woman hours to please him due to his insatiable nature, but you — your cunt clenching around his cock for dear life milks him dry, and inch by inch he pulls out, watching the hot liquid dripping down your trembling thighs. Art, he thinks, this is what art is — your face buried in the pillows, ass up, and his seed spilling out of your sore cunt. You come down from your haze, slowly but surely, and the realisation of what just happened begins to hit you. You want to regret everything, to feel a shred of shame, but there isn't any left. After this night, Sukuna irrevocably owns you, and you wouldn't have it any other way. He lays on the bed, lazily watching you stumble in the bathroom to clean yourself up, but with his guard up in case you want to try anything stupid. Yet when you don't come back, Sukuna wonders if you ran away out the window, which makes him laugh to himself because he could find you anywhere if he wanted to. So, he drags his feet across the room, finding you on the edge of the bathtub, watching the water pool inside with a blank stare. When you feel his presence, you get up and tug at the hem of his shirt. The man flinches, until he remembers that you are harmless and exhausted, and you don't look like you even want to put up a fight, so he allows you to take his shirt off. "Is this for me?" He points at the tub, brow quirked and a mischievous smile on his lips. "Yes." "Are you gonna clean me up?" "Yes." You sigh, wondering if you truly ever loved Yuji, wondering why you didn't even try to fight for him. "Do you want your boyfriend back?" Oh, how you dreaded this question. You cringe at the words, and don't reply. Silence is also an answer, but he's cruel. "I need to hear it." "He will also hear it." Of course he will, that's the whole point of humiliation. Sukuna steps in the tub, dipping himself in the hot water, a hand extended towards you. "Join me." You hesitate to take his hand, lips pursed and eyes narrowed at the man who looks so serene that it amazes you how brutal he was before. "I won't ask again." Complying, and not wanting to anger him, you don't waste another moment to get in the tub, back against his chest. "Can I ask you a question?" "You just did, sweet dove." "Fine, I’ll shut up." "Now, now, don't give me that attitude, or else I'll have to put you in your place. And you won't like it." His nails are pressed onto your jugular, and you know those things can cut, your hips are still bleeding. "Ask away." He lets his hands fall on your shoulders and you exhale the breath that was caught in your

throat. "Why didn't you kill me? Why don't you kill me?" "I need a pet." "Oh." Your disappointment makes Sukuna burst into laughter. What did you expect? A confession of love? "Oh?" He mocks you, tracing circles on your skin with his talons. "Don't worry, I take good care of my pets. Especially if they're loyal and obedient." His hands travel down your body, one pulling your knee to the side, the other moving up your thigh. "You are loyal and obedient, yes?" "Please, no more-" The rest of the sentence dies before you can utter it when his fingers ghost over your swollen clit. "Answer me, Y/N." "I can't come again!" "You can, and you will, because I want you to. Now answer the fucking question." Sukuna toys with you, only pushing his index finger one knuckle deep between your folds before pulling it out, and somehow you can't feel the sharpness of his nails. "Will you serve and obey me, not once questioning my authority?" He pushes the finger back in, curling it upwards and you don't fail to clench your walls once more. "Oh, f-fuck, I will, I will! But please, I can't–" When he rubs your clit, you are done for. You didn't think you could reach another climax, but those circles he's rubbing with enough pressure to both give you pleasure and pain have you melting in his arms. "Swear it, then. Make a pact with me. I can give you anything in return, maybe even the brat." "I s-swear it, S-Sukuna! I swear my loyalty to you!" You hiss between your gritted teeth, hips rolling in synchronicity with his hand. "And in return, what do you want?" "I want you! Oh, god, I only want you!" "Clever girl." The man decides to give you what you want, and with a quickened pace, you squeeze your thighs together, coming undone on his fingers. "I'm going to enjoy your company." Embracing your true nature is your salvation, and damnation. Your boyfriend is never coming back, Sukuna simply won't allow it, and from this moment on, your memories of Yuji begin to fade away, like a bad dream, because you simply must serve your beloved master, your merciful and devastatingly powerful god. That's who you really are.
