The school is blatantly empty today, which was rather boring. You had decided from the moment you woke up, that this would be the day you saw Sukuna’s supposed vessel. How disappointing to notice everything so empty, like an abandoned building. No Gojo, no other first years, whatever. It was all lame.
Huffing to yourself you open the door to another spacious classroom with zero people intact. You thought to even check the nurse’s office, only to see Ieiri doing who knows what with the bodies there. She turns up at you as blood adorns her lab coat, “Oh, hey, what’re you doing here?” You blink and close the door. She shrugs and diverts her attention back to work.
Where else could they be? Principals room? Sealed room? Ah possibly there.
You make way for the chambers, passing the empty hallways. The year above you's class is more than interesting. There's a panda, a dude who speaks in rice ball ingredients, and a zen’in lady. The lady was also able to keep up with your rude remarks which was amusing.
As you walk you hear small far away grunts. Humming, you curiously begin to switch directions, and near the sounds of groaning and “Hyah’s!”
From far away, you’re able to see a faint, puffy pink-haired man slapping a training dummy with a weird fuzzy blade. He’s so caught up in training that he doesn’t notice you, so you watch, judging his stance and how he struggles while dragging his breaths.
Though you’re amused at the pure confidence brimming in his expression; he was almost cute it's laughable. Eventually, that makes its way from your mouth, and he shifts to you, completely oblivious that you were even there that whole time. He’s a bit taken aback, and you near closer to see him.
“Um.. who are you?” He asks, dumbfounded.
You press your hands to your waist ignoring the question and direct one back at him “Are you a first-year?”
“Yeah. Are you one of those second years? Did you guys already come back from your mission?”
You shake your head, and point to him exclaiming loudly, “No, I’m with you! Yuji Itadori!”
He blanks, “Uh.. okay..” you squeal, throwing your hands in the air.
“I knew it! Sukuna picked you? Look at that, you’re so innocent looking, you’re not even holding that blade right.” You giggle to yourself obnoxiously and he tilts his head, a small flicker of annoyance inside him.
“Actually, he didn’t pick me, I just swallowed one of his fingers and-“ you cut him off with a sound of disgust.
“You did that willingly? Ugh, how interesting, what did it taste like? Was it crunchy? Gooey? Was it old?”
He ponders for a moment before answering, “Old, definitely old, and wrinkly.. and his fingernails are sharp.”
“Ew.” You cringe at the thought, and he tilts his head to ask, “So, what are you here for?”
Shrugging, you think. “I just wanted to see,” you answer vaguely. Being Sukuna’s vessel is more than interesting, considering it’s been what, hundreds of years?
He opens his mouth to speak and you look at his cursed tool, probably one that was given to him by Gojo. Something in you wants to admit the morbid curiosity of seeing Sukuna, but in reality, you know that would be terrible.
“So, how does that work? Do you just have him inside of you? Does he talk? Do you hear him? See him like a ghost and he talks to you, is he standing here right now?” You ramble all your ideas at him and he rubs the back of his neck awkwardly. You were definitely weirding him out.
“No nothing like that, though I do hear him every now and then. It’s sort of annoying.” He points to the back of his hand, “or he’ll show here.” You tilt your head, weird.
You move close to him, enough to invade his personal space. You lift your hand and he’s confused, then you dive it down on his head, patting the fluff.
Beaming, you pet him mockingly while cooing, “I heard you’re going on your first real mission tomorrow, how exciting.”
Yuji lightly slaps your hand away, grumbling, “Can you not do that?” he steps back so you would no longer be at arm’s length.
You smile. Truthfully, you were planning on being more annoying. Why? Well, you're not sure. You quite liked him instead, he was cute, and you know you're going to enjoy teasing him often. He's still fussing over his hair as you think until you twirl away with a laugh.
“Hey, tell Sukuna I said hi when he saves your ass from death.” You stick your tongue out at him and Yuji furrows his brows immediately. That annoyed him.
Safe to say, Sukuna was definitely amused by you since then.
Yuji is your boyfriend, and he's someone you love to death even if you can still tease the heck out of him. But you've calmed since then. And through the years nothing ever came of Sukuna. Many times you had even forgotten he existed.
Occasionally you two would get food together, and sometimes you had a morbid curiosity when remembering after all this time.
“Does Sukuna still talk to you?” You’d ask and he’d turn his head to the side with a grave expression. He knows, but he never admits.
“No, not really," he'd mumble to himself. You’d nod in response, giving him a knowing gaze. Was it really that bad?
From the day he first met you to now, all that was always on the curses mind was how he just wanted to kill everyone and have fun with the punk’s lively girlfriend. Luckily, that day never came, and it never will.
That was until.. he got sick of course.
You’re patting the washcloth against Yuji’s head, a worry setting a deep frown on your face. His breathing is heavy, and he's panting with a newfound flame that burns in his forehead. He’s hotter than you’ve ever felt, it was almost inhuman. No reverse curse technique seemed to have been helping, no doctor, no medicine, no bath, no rest, just nothing was working.
You’re rushing to look through Yuji's cabinets. There has to be something here that you haven’t seen before. No simple pain medications would help, nothing generic. You pick up a bottle, maybe this one? It was a herbal medicine, and you knew it was a fat chance, but you’re desperate. So you rush back to Itadori and pour him a small cup of water near the pills.
“Hey, Yuuji.. baby,” you lightly caress his cheek, but to no avail. His skin is steaming, and his eyes are clasped shut.
You frown and take the pills in your hands, pouting at what you have to do. You open his mouth and drop the pills in lightly, holding his head up at a good position, then making sure a very small amount of water is poured in so he won’t choke. This reminded you of something, but you weren’t sure of what.
Setting the cup back down you stare at it, then him, then gasp as a bad thought strikes you. Sukuna. The only person who can heal him.
You can’t do that. Sukuna only works for his own gain. He probably wouldn’t even care if he died with Yuji. But still, you won't just let that happen.
Albeit.. are you really going to allow possibly hundreds, if not thousands to die by his hands just because you selfishly want one man to live? Emotional connection or not, that wasn’t smart. Or is it?
Yuji is probably the only person who could hold Sukuna off- or not probably, he is the only person who can hold him off. Maybe besides Gojo, but that didn’t count when it came to a literal internal affair.
Either way, the fingers are all stowed somewhere. Surely you could find one. but still, you’d rather not have the god of curses of all beings roam around. You knew Yuji wouldn’t want that either, in fact, he’d probably be disappointed.
You sigh and pat Yuji’s head, giving him a soft kiss on the forehead. “Hope you get better… I’m gonna go now, okay?” You stand and stare at him, knowing he probably couldn’t hear you, or respond. You were sure he was deep in there somewhere, maybe even kicking Sukuna’s ass.
Sighing, you arrive at your home and slam your back into the bed, draping a hand over your forehead. You’re exhausted. Lately, you’ve just been spending days and nights at his house.
Sometimes you aren’t able to sleep depending on the day, this time might be one of those, but you aren't sure.
Battling with the idea of Yuji’s worsening sickness and Sukuna’s possible revival made you almost get a migraine.
You glance at the time. It’s already been a full hour, and your corneas are burning from the lack of sleep. Alright.. suppose it was time. You sigh and make yourself comfy, curling in a small ball before closing your lids.
When you awake, there’s a blur in your eyes as you tiredly open them. It’s dark and when you glance at the window you’re thinking it’s maybe 2 AM. 3? Rolling over to your side, you pull your leg up and get comfy again, groaning at how hot your pillow now is. Lifting your head to turn it, you slam back down comfortably, a flicker of pink in your sight. Yawning, you rub your eyes and blink at whatever that could be, but decide eh, whatever, it’s your room, nothing out of the ordinary. What you needed was sleep for tomorrow.
Shuffling, you clutch your pillow and squeeze it against you, loving the feel of the brisk cold that rubs against your cheek and satiates the heat of your neck. Closing your eyes with a small moan, a faint chuckle sounds near you. Blinking your eyes open, a jolt of fear slithers down your spine, and you raise your upper half and rotate to survey the room. Nothing out of the ordinary. You’re tired, just hearing things.
Huffing, you press yourself against the pillow again and clench your eyes shut. Just go to sleep damn it.
This time you heard an audible step. Your heart sped into your chest and you forced yourself to rotate the other way. You’re just hearing things, lack of sleep will do that to you, it’s been a long day too, so surely it’s that.
Step. It must be a curse, but you didn’t feel anything, so it had to just be you. If you go to sleep now, then it’ll all be gone. Just keep closing your eyes and when you open them again it’ll be morning.
Step. You squeaked at the sound and the creak in the floorboards. That’s when you heard another chuckle.
“How long are you going to feign sleep?” A raspy deep voice erupts a squeal from you.
Turning shakily, you struggle to adjust to the lighting as you see a familiar figure ahead. “Yuji?” Your small voice whispers out. He grins wide. No, something was not right here. Yuji didn’t have markings or whatever this was on him, and he never kept his bangs back.
When you glanced down to study his body you froze. There was a hole in his chest, not an incision, not a Halloween effect, a full-on hole that you could look inside of. Blood was dripping from the wound, but it seemed as if it was drying judging by the goop.
A realization hits you, and you gasp, your body shaking under the weight of Yuji- no Sukuna's gaze. His smile is large, and his dark orbs glow red in the darkness. “Y-You’re…” you hold your breath.
“H-How..?” You’re still whispering, tremoring as nears your features. He suddenly laughs loudly, cackling horribly with that new voice of his. It echoes into your ears and makes your heart drop. This was it, you were going to die.
“You see, I was planning on having fun with that other lively girl. But, because of the brat’s affection for you, I have decided to pick you first.” He has a rumble in his hoarse throat when he verbalizes, and a horrifying smile still paints his face. You’re stuck, shaking in your spot.
“A-Are you..” you struggle to think of the words, your voice cracking as he gleams at you. “Going to.. kill me..?” Sukuna’s grin widens, and finally, you can see the way his double pair of eyes glimmer even in the lack of light.
“After you’ve quenched my insatiable thirst, then yes.”
He takes a moment, pausing to press his hand against his chin as he thinks. “Or perhaps I’ll bond you to a life of servitude, whatever amuses me more at the moment.”
You know he’s more than serious. You had to do anything, talk, and keep on conversing until he got bored. Reason with all your might.
You attempt to continue as you swallow hard. “B-But… Yuji will switch back.” He had to switch back, right? Won’t he? Or does the hole in his heart not prove to you enough that he won’t be able to?
“Unless the punk wants to die, then he’ll have to be my guest. But he seems to be struggling at the moment, so, I’m going to take my sweet time with you.”
He gets close, his finger twirling around your hair.
You bawl your fist into the sheets. You have to escape. You have to. Your legs quietly press beneath you, as if readying for a sprint.
“If you so as flinch I’ll make quick work of your death.”
Suddenly you’re rigid as can be, terrified that the quaking in your heart and the stammering in your hands would get you killed. All you’re doing is heaving, barely able to meet his gaze.
“Now bow.” He commands and you quickly rush to cradle your head between your hands that lay flat against the bed. He enjoys the scene, delighting in the fear.
A second passes, and you’re flipped on your back with a strength you’ve never felt before. It was enough to bruise you just from the sheer weight. He lifts his clawed finger and suddenly your clothes are ripped, and before you can think to cover yourself with a blanket or anything he’s over you, staring into your desperate eyes.
He was truly a pure evil that no one could think to reach.
Tears are forming. You’re terrified. “Please don’t,” you mutter weakly.
He cackles loud enough for you to flinch. He won’t kill you yet.
The glimmer of his teeth when he grins wide makes you gasp. He’s snickering to the point it becomes manic laughter, and it makes you sick to your stomach. It sounded nothing like Yuji. His laughs are always a lot lighter and sweet.
Sukuna sighs longingly to himself, trailing his fingers down your body as you cry. “It’s been a thousand years, and I will never stop delighting in these sweet whimpers.” His palm meets your cunt. He presses against your clit hard and you squeal out from the pain. He doesn’t care for your enjoyment. All he wants to do is force himself down your tight hole and release every bit of cum he's had stored up for years.
“To believe the fool hadn’t claimed you, what a shame.. for him. A treasure to me.” He’s chuckling as he kneads your clit more. It’s impatient and mean, but it gets you wet enough. His middle finger promptly shoves inside you, and you whine at the pain, curling your toes into the bed. Blood drips from the wound, lubricating his finger to pulse into you more. Sukuna grins at the liquid, and he’s purposely speeding up his pace.
Tears swell in your eyes. You always wanted to save yourself for Yuji. Save yourself for the perfect moment.. and Sukuna just took everything away from you.
“A thousand years and I get a virgin, ah I just delight in it, this is going to be fun.” His eyes are glimmering wide, brimming with joy as he adds another finger. You hiss at the sudden discomfort. His other hand moves to your neck, but it pauses, just hovering above it. You gulp tightly, scared for what was to come.
“On second thought,” he pulls away and uses his free hand instead to circle your clit harshly. You’re tensed up, quivering with the pain of him spearing you mercilessly while gasping at the pleasure of your clit.
"I wouldn’t typically allow you the pleasure to breathe, but since you’ve never felt this, your cries will satisfy me more," Sukuna grins. If it wasn’t for the need to stretch you out, he wouldn’t be doing this at all. But he enjoys the way your cunt attempts to swallow his fingers whole as if attempting to expel him. He forces another in and you gasp at the sudden intrusion. You’re hands are clutched around your sides desperately as you moan and cry.
His fingers are fucking you furiously, eventually attaining a pleasant amount of wetness from your cunt. The obscene sounds feel as if they’re blaring in the room. You’re still tense as could be, but once he finally takes them out, you slump in response, heaving in relief.
Sukuna chuckles evilly at the slick surrounding his fingers. As if it wasn’t a moment ago that he had just broken you and stretched you wide.
“Ah, virgins. So easily excitable.” He breathes in delight to himself. You’re quivering, attempting to remain stiff, but every time his hand grazes your skin you flinch. You forcefully drape your arm over your sight while streams roll down your cheeks. Whenever you would glimpse at him all you wanted to do was cry and run.
There’s no remorse in him, no guilt, nothing but happiness as he lives his fantasy.
You feel his tip suddenly poke at your entrance, and you don’t even feel how clenched up you are. Your teeth are dragging against one another in anticipation, and he attempts to push in. You can’t help but peek fearfully, and you tighten at the sight. Sukuna gazes at you, annoyed. You shiver. Did you move? Did you do something wrong?
Quickly you’re spun around, your chest landing on the bed and your face bouncing off the pillow. Your view is met with the headboard. You can’t see anymore, and you panic. Your head moves up and you attempt to turn your body to fixate on him. He forces you back down instantly with a grip on your scalp. It tightens and you're shoved into your pillow hard.
When you attempt to move, the strength increases. His sharp fingernails are grazing your skin, almost drawing blood. You can’t breathe. You try to take an inhale and you’re stopped by the force of the pillow stuffing and blocking your airway.
Without warning your pussy is spread wide by his cock and you scream incoherently. He instantaneously groans loudly at the warmth that meets him. His gaze turns to the ceiling, and his eyes are practically rolled to the back of his head as he relishes the feeling. He’s been waiting centuries for this exact moment. This scene has been revolving in his mind since day one. The idea of forcing a helpless virgin on their knees and taking them completely.
“Ah, I thought I’d never feel this again.” He exhales a deep breath of satisfaction, “It’s wonderful."
Your tight cunt swarms around his cock, sucking him in helplessly, and he groans, a newfound lust within. You're struggling to swallow his size, quivering as you feel your pussy forcefully stretch. You cry into the pillow, convulsing beneath him. He’s usually a patient man, but not this time.
He moves, gripping your head tight and pulling you down while he begins to pound you murderously. The brutality of his thrusts while you gasp for air has you thrashing around, adamant to get him off of you. He has no care. He'd make sure he would let out all of his frustrations from being in your punk-ass boyfriend’s body for so long.
“Do I need to remind you of what I’ve said? That would be rather impolite don’t you think?” Sukuna breathes heavily, annoyed by your muffled screams. He rams his cock to the very end of you and back. He's huge, and it burns endlessly when he thrusts. You’re shouting against the fabric, desperately attempting to shake off the force and lift yourself for just one inhale. He was going to kill you and defile your body. This is how you’re going to die, in the worst possible way.
He’s using you like a mere plaything. Eventually, the pressure rushing to your head starts to make your vision go dark. You limp against him as he fucks you senseless. Sukuna starts cackling, and he pulls your weak head up, watching you come to life with a heavy inhale. Tears are pouring down your cheeks, drool falling from your lips as you greedily heave. He's still bucking his hips sharply into you, slapping your ass hard.
Sukuna would've sneered, but there was a large amount of impatience beginning to surge. “Now, if I need to remind you again, then the next you won’t be breathing. Not that it matters to me. But you wouldn’t like that, would you?" His tone is dark, and you shake your head a complacent no. Anything to not go through that again.
He slaps your ass with a rush of strength, making you jitter against him. He pulses into you, enjoying the way your pussy is now melting into a wet slop.
“It appears you enjoy this just as much as I.” You’re sputtering with your breaths, unable to even hear him chuckling as he slams into you. Your hair is suddenly pulled back. Sukuna is grabbing a fistful and the ache in your neck has you groaning uncomfortably.
You’re moaning nonsensically and his pace is merciless. “How cute, maybe I will keep you alive.”
His tug is impossible to push back at, and you yelp when he pulls you even further. He’s still slapping your ass repeatedly and you’re squeezing tight around him at every hit. His force is painful, and he finds it amusing. He only thrusts himself to the brink of his own orgasm while yanking you like a rag doll and stretching you wide.
You’re whining desperately as he speeds up, and a jolt of electricity rises. It pulses into a quivering release while you slur incoherently, subconsciously circling your hips into him.
Sukuna breathes hard against you, merciless excitement running through his veins as he pulls you back hard and fucks your exhausted core, all while you still ride out your climax. He finally hits deep inside of you, reaching the furthest his cock can and even more. There's a sudden warmth in your walls as a heavy thick stream of cum pours inside of you.
“How I miss this.” Sukuna exhales loudly, nearly moaning at the sweet release. His clutch on your skin is still tight, causing you to jolt beneath him.
And It was only a few moments that had passed before he left your sore cunt, only to push himself back in and slam into you. You’re a slop, whining desperate slurs into your pillow as he fucks you senseless.
You don't know how much time passed, but it never stopped. You found yourself eventually heaving and imagining a place where this wasn’t happening. Where Yuji was alive and he was the one taking you instead.
Sukuna had whirled you around, pushing himself deep into you, his tongue dragging against your neck. Your legs are barely gripping his as he pounds you beneath him. His grasp was tight on the sheets beside you, and you were just relieved it wasn’t on your skin anymore.
Suddenly a rush builds and you’re whining loudly, your thighs feeling a new strength as you clasp around him. Your hands don’t dare to grab him, but as you lose yourself in your orgasm you can’t help the way you claw at his back. Sukuna pulses into you and lets out another stream of cum. The eventual number you didn’t know. Tears were rolling down your face, you're tired, you just want it to stop.
“No more.. please,” you whisper desperately.
Sukuna snickers into your neck, breathing not nearly as hard as you were. He pulls himself from your throbbing hole and you still manage to whine at the loss. Relief follows swiftly, and the cum that clogs itself inside of you drips slowly.
“Did you think a mere few climaxes would be enough for me? You truly don’t understand.” His tone gets low as he grins. “I am going to keep playing with you until I get bored.” You pant exhaustedly, barely able to register his words. You just want to go to sleep.
As quick as that relief had come, it diminished the moment he buried himself in your cunt again. You whimper and let out a choked breath, eyes practically rolling to the back of your head. His deep breath brushes your skin, his groan rumbling something deep within you.
“And yet you have joined them all so wonderfully. It’s been so long since I had a woman keep up with me,” he beams wide with that evil sparkling in his red eyes.
“I’ve decided I’ll let you live. I’ll keep you by my side whenever I feel the need to use you.” At his words, sobs begin to overtake you. He grips your arms tight, pushing into you repeatedly and cackling maniacally.
You would never be free from that grating sound ever again.
