Chapter Text

months of watching, yearning, obsessing. and now here you are, beautifully laid out across his bed, sleeping soundly. it seems the drink he gave you worked pretty well. sukuna looms over you, his shadow casting upon your body.

“pretty thing,” he mumbles, palming your cheek. he gropes your breast, massaging your soft flesh, and then leans down, nuzzling his face against the crook of your neck - taking in a deep breath. you smell as good as you look. unable to resist any longer, he decides to pull your shirt up and undo your bra while you are still unconscious.

“i was going to start once you’d woken up, but it seems i’ve lost my patience,” he tells you, knowing that his voice isn’t reaching you in the slightest bit. he brings his mouth to your chest and suckles on your perky nipples, grinding his bulge against you. he ties your arms up, just in case you decide to get feisty with him when you wake up.

once he slides your panties off, he hums as he uses a thumb to ghost over your clit. oh, how he wants to bury his cock inside you, right fucking now. he’s been waiting for this moment for so long.
“not yet - not right now,” he tells himself. 

“i want you to be awake for me.”

***

soon enough, groggily, you wake with him in between your legs, having been getting a taste of your juices as a way to pass the time while he waited for you.

“oh - you’re finally awake, sweetheart. took you long enough. did you have a nice dream?” he asks, pressing a kiss against your slit.

the sleepiness fogs your mind, and you only feel confused as you look down at the man you’d only recently started talking to, a few weeks prior. the last memory you have of being awake, is when he offered you some tea whilst you were sitting in his living room. when the pieces come together and you realise what’s happening, something snaps within you and you try to bring your arms down, only to notice how you’ve been tied up against the bed frame, rendering you immobile. panic ensues, and you flail around with a single yelp, breathing unsteady.

“shh, love. i understand your sentiment - but do try to calm down,” he coos at you, pinning your legs to keep them still with an iron grip. enough to prevent you from moving, but not enough to hurt you.
when you look at him with widened eyes, expression pooling with nothing but fear, sukuna feels a bit of hurt stir up inside of him. fear wasn’t what he was looking for, here. but it’s okay. you’ll learn to love him eventually.

you’re about to throw questions at him, scream for help, hoping this is just some sick joke, but he puts his tongue onto you again. his taste buds caress your clit and the way he suckles makes you gasp.

“no! stop-! i don’t want this,” you sob, feeling a sense of betrayal, wondering if this is the same person you’d been crushing on for those past few weeks. the person who could fluster you easier than he could breathe. he got you shy and giggly in every conversation you had with him. you dig your nails into your palms, desperately begging to wake up from this nightmare.
“you say that, but you’re getting wetter down here,” he stops momentarily to tell you. in denial, you shake your head with tears running down your cheeks.

“i don’t want to make you cry, sweetheart; but you sure as hell look pretty doing it.”
the way he looks down at you with his lustful, crimson eyes is enough to make you feel delirious. you feel as though they could haunt you in your dreams forever.

he then continuously pulls orgasm after orgasm out of you, using only his mouth. tongue snaking inside and out, swiping across your swollen and aching clit - making your tears of fear turn into tears of pleasure. you gasp for air like you never have before, hips bucking into his mouth, out of your control. it distracts you from the pain in your wrists, the binds bruising them from how you’re tugging so wildly.

please, sukuna- no more-” you cry out weakly, a whimpering and twitching mess.
he pauses from the way you say his name.

“...i can consider it, if you say it again. my name,” sukuna says, detaching his mouth from you, a trail of spit following his lip as he pulls away.

“sukuna…” you let out without thinking, doing anything you can to get him to stop overstimulating you. the way you pant his name sends a dizzying throb into his dick. you watch as he sits himself up, only to unzip his pants and reveal his girthy, twitching cock - tip already dripping with precum.

“i-i thought you said…” you attempt to argue, tugging at your binds again, wanting to get away.
“oh doll, this and that are different things…be good for me, won’t you?”
“it won’t fit! too big,” you cry out in alarm, looking down at it.
“we’ll see about that.”
“wait-!”

you can’t protest any further once the air is pushed out of your lungs as he slides in with one go, his tip kissing the entrance of your womb. you shudder at the way he stretches you. sukuna has a firm hold onto your hips, and groans deeply from how you’re clamping around him. this is heaven. he’ll never find anyone even half as perfect as you.

“look, i’m all in. wasn’t that bad now, was it?” he asks as he wipes a single tear away from your cheek. you don’t give him a response, only weeping softly.
“aw, come on. i’ll make you feel better very soon,” he reassures you.

he starts at a slow pace, letting you get used to his size for a bit.

he’s restraining himself - as much as he wants to start pounding, he wants your first time with him to be something special, not painful. he pays utmost attention to your every change in expression, burning this image of you inside of his mind, so he can visualise it again and again even after this moment is over.

“you’re doing so well, love. you were made for me,” he tells you, his own breath becoming uneven as he drags his cock in and out of you at a lenient pace, reaching deep inside every time. the first time you show yourself sighing in pleasure, is when he runs his tongue over his own lips lasciviously to wet them, before beginning to speed himself up.

choking out a moan, your brain numbs from the intensity. you don’t know how it happened, but your legs have wrapped themselves around his waist, bringing him closer to you. sukuna has a salacious grin plastered over his face - and when you make eye contact with him, you seem to get absorbed into that gaze of his, holding nothing but fierce infatuation. it’s overwhelming. you shut your eyes tight and turn away to avoid it, biting on your lower lip.

his hand comes up and holds you by the jaw, turning your face back towards him.

“open your eyes, sweetheart,” he tells you, thrusting in a particular way that makes you quiver, “i want you to keep looking at me.”

remembering the sheer strength of his you experienced first hand when he pinned your legs down just moments before, you pry your eyes back open in fear.

“so obedient,” he emphasises, bringing his face closer to your ear, warm breath fanning your skin. you feel so good around him, and he’s losing those little bits of restraint he had left in himself. nothing could prepare you for the way sukuna begins to pound into you, hips meeting hips, your pussy getting stuffed with every inch of his thick cock. you helplessly cry out, thighs trembling. he feels it around his waist, and chuckles.

“hitting a sweet spot, am i?”

sukuna’s eyes flicker over to your tied up wrists. he wants to feel your arms around him. feel your nails raking down his back. feel your sweaty palms against his skin. it’s a risky move, but he slowly unties those binds as he keeps thrusting, freeing your wrists, curious as to what you’d do in this state.

there’s a sense of immediate relief as they loosen, but it goes over your brain that you’ve just been freed. instead, your hands fly over to his shoulders for support, and you don’t realise you’re doing it. he deems it satisfying enough.

adrenaline rushes through his veins, and nothing but the thought of fucking you and fucking you and fucking you invades his mind - you look so gorgeous under him, an absolute mess that makes you all the more charming. he doesn’t look away from your eyes for a second, and neither do you. those swirls in his pupils, they seem hypnotising, and you can’t help but get sucked into his stare.

what surprises you, is the way sukuna kisses you as you get sent into another orgasm - his lips so soft, his tongue caressing yours so passionately, as if what he was doing to you wasn’t so hideously wrong. it leaves you in terrible confusion, even as he moves away from the kiss and continues to thrust into you before releasing inside. you should be hating every second of this.

he holds you so close as he grinds out his orgasm, breathing heavily while his cock twitches with every spurt of cum that spills within, and he only realises that you’ve passed out once he feels your weakened grip on his shoulder.

moments after, the water inches up against the bathtub walls as he fills it up with warm water, small gusts of steam rising along with it. sukuna gets inside of the tub with you in his arms, and adjusts your body so that your back is against his chest. noticing the bruises left behind on your wrists, he lifts one of them up and presses his lips onto it - as some form of a silent apology.

 

***

you refuse to eat.

it is rather peculiar, how he cooks every meal and plates it nicely for you at the same times of the day - regardless of the way you turn your head away from it with empty eyes, mouth set in a straight line. he is patient with you. he knows how much you must miss your family, friends, your former day-to-day life. but he promises that you’ll get used to this, used to him

every night, he sleeps with you in his arms, embracing you tight enough for you to hear the beats of his heart. things would be much more comfortable if it weren’t for the chains around your ankles, creating noise if you do so much as take a single step. sukuna has varied its length quite meticulously - so that you can only reach places around his house where he allows you to.

he is concerned. you’re thinning, and it’s been a few days since you haven’t taken a single bite to eat. even as he’s started working again, he always comes back home to see his food untouched.

you think he doesn’t know what you’re up to, while he’s not around? he notices it all, the slightest shifts in the placements of his furniture. the small evidences of your attempts at seeking for an escape. he notices it, but doesn’t say a word to you. he’ll let you figure it out for yourself, the futility of these efforts.

“why are you doing this to me?” you croak out, one morning - as he’s getting dressed to go out again.

“...’why’?” he repeats back, putting his tie on. “because this one-sided obsession pains me.”
There is a long, deafening pause before he says the next sentence.

“i need you to want me, like the way i want you. love me, like the way i love you.” he turns around to look at you with a calm expression.

“but that won’t happen if you keep skipping meals like this. i fear you’ll die before we even get to start.”

he plays with a few loose strands of your hair, twisting them between his thumb and index finger.
“your loved ones are roaming around outside in search of you, sweetheart. i hate to take such drastic measures, but if it’ll get you to eat, i have no qualms on-”

sukuna stops himself when you grab the hem of his shirt, trembling greatly.
his touch is gentle as he takes hold of it, smiling. 

“i’ll be back, love,” he says, after leaving a kiss onto your forehead. 
it somehow, sends you deeper into the depths of this hell.

later, when he comes back in the evening, he is put into a pleasant mood upon seeing your empty food plate for the first time. it is only then, you realise why he’d been so intent on knowing what your favourite dishes were, back when you thought he was just a normal man.

 

***

a few weeks have passed since you started eating again. at some point, you’d gotten ill, riddled with fevers and headaches. sukuna comforted you with great care, consistently changing the cold, wet cloth on your forehead during the nights and feeding you warm soups that were easy on your stomach.

those days went by like a fog - you couldn’t think straight and could only cling onto him for support. and he gladly enjoyed your vulnerability, taking this chance to hold your hand a little longer, help you bathe, stare at you while you slept. he didn’t like seeing you so ill and fragile, but couldn’t help thinking that it brought you closer to him.

he hasn’t touched you in a lewd manner again since that first night and it makes you wonder. he could do anything he wanted to you, if he so desired. why was he treating you so…

your thoughts are interrupted when the hair dryer stops, and sukuna puts it down beside the bathroom sink. his fingers interweave through your locks, checking if there are any spots that he’s missed. he picks up a brush and begins to smooth it out.

“what are you thinking so intently about, love?” he asks, as he continues to brush.
he always firmly insists that he does this part for you, claiming that he likes looking at you through the mirror.

“...nothing,” you lie to him, avoiding his gaze.

for sure, you catch on that he knows you’re refusing to say what’s on your mind. but he again, doesn’t confront you about it. only hums as finishes up, and then brings you back to his room.

once you’re sitting on the side of the bed, you’re looking down at him as he crouches at your feet.

“do you really love me?” the question that comes out of your mouth surprises even yourself.
sukuna seems a little stunned by the abrupt query.

well, at least that’s what you assume. you can’t see his expression because of the way he’s facing your feet. he doesn’t answer immediately, only finishing up those shackles around you first. when he looks up at you afterwards, there is the softest smile on his face as he brings your hand to his mouth, giving it a small peck.

“yes. i love you - from the very bottom of my heart.”

the chains have never felt heavier around your ankles.

***

and so, you’ve somewhat gotten accustomed to living under these conditions. little by little, you notice how he’s loosening up the walls he’d built around you and the outside world. he lets you watch tv when he’s gone, instead of just restricting you to the books in his collection. sometimes he brings you to the window to let you peer at the blue sky, even opening it up for you to get some fresh air when he’s in a good enough mood for it. often, you find yourself anticipating his return home.

it’s morning, on a weekend. you can only tell its the weekend because sukuna is staying home today. you hear him in the kitchen, chopping up what sounded like vegetables in the kitchen for breakfast. when he’s able to eat all three meals with you, he likes to go all out with his cooking.

turning the tv on, the news that happens to take over the screen is a missing persons case. your eyes widen as your face is shown. the reporter says your full name. the chopping sound from the kitchen stops.

your hands are shaking as you switch to a different channel immediately, to a random soap opera, side-eyeing where sukuna stood still. a few seconds of quiet passes - with only the tv noises ringing in the air. you almost let a sigh of relief out when he resumes his chopping.

however, the shock from the news makes your head sting. like a wake up call. what are you doing here? don’t you want to see your family and friends? they must be spreading awareness of your disappearance. your heart ached for them.

but how? sukuna has you in an iron grip. there is not even a small ounce of opportunity that he allows for you to escape, not when he’s not around. you’d have to think of an elaborate plan-

“sweetheart. breakfast is ready,” he tells you, coming up to embrace you from behind. the suspicious timing makes all the hairs on your body stand up. relax. you have to play nice. act like nothing is wrong.

you touch his arm and smile nervously at him.

***

the clock ticks in the middle of the night. you wake, but not purposefully. you sit up, and look back at sukuna, who is still asleep. your mind remains empty for a few seconds, and you shift your legs without thinking - only to notice how unusually loose they feel.

quietly, you lift the sheets. your intuition is correct. they are not fastened properly, and you can easily pry them open. you put a few seconds to waste just from the sheer surprise you feel. do you dare believe that he could’ve been so careless enough to not tie you down properly?

it doesn’t matter, you tell yourself. the only thing that matters is that the chains are loose and that this is possibly the only chance you’ll have to get out of this place. with a hitched breath, you slide your feet out of the shackles, and carefully get off of the bed. he does not stir while you do this.

cautious steps take off across the hall as you head down to where the entrance to the house is. normally, your chains aren’t long enough for you to venture out to this area of his place. all the windows have been bolted shut. and to your dread, there is a lock that keeps the door in place, keeping you from your freedom. you have no idea where the key might be.

with a frantic mind, you head over to the nearest room you could find and start rummaging. it could be anywhere.

a few hours pass, and there is still no sight of the key. frustrated, you fumble an object and it goes tumbling off the desk, onto the floor with a loud noise. freezing up, you stare at the fallen object, unable to move. the silence that follows is unbearable - and you can’t tell if that might’ve been loud enough to wake him or not. you make your way back to his room, with your heels raised up.

hovering at the doorway, you breathe out quietly, as you see how he is still in the bed, chest rising and falling at a slow pace. in a couple of hours, the sun would rise. you have no confidence of finding the key without accidentally alerting him before then. your eyes ghost over the chains, which gives you an idea. you can put him into captivity.

however, you stop after only having taken a couple to strides towards him. various thoughts run through your mind. what if the key was hidden somewhere around here? hidden cleverly by him in plain sight. he could reach and stop you easily. once he traps you in his arms, it would be game over. defeated, you retreat with balled fists. 

mindlessly, you enter the kitchen. by this time, your eyes have adjusted well to the darkness around you, so you are able to catch sight of the knife holder that is placed upon the counter. one of them hasn’t been pushed in all the way, so a section of the blade can be seen from where you stand.

…dead. if he’s dead, you’ll have all the time in the world to find that key safely.

your hand seems to wrap around perfectly against the handle, and it feels comfortable to hold. 

when you actually stand before him, all that determination you had suddenly washes away from you. in replacement of it, comes panic. you cannot help but question yourself. is this alright? is it okay for you to do this? his words, i love you - from the very bottom of my heart, haunt you - and you believe that they will continue to, for the rest of your life.

you bring the blade closer to his neck.

love me, like the way i love you.

your breathing becomes unsteady, and the knife suddenly feels dense, too dense for you to be holding, and you can’t seem to bring it down into his flesh. a cold sweat breaks out upon your skin, and a million different thoughts scatter within your brain, all at once. conflicting emotions and adrenaline course through your veins, and yet also, those feelings you’d felt when he enveloped you in his warmth came by in flashes, throwing you into disarray.

“go ahead. do it.”

his voice instantly silences the chaos inside of your mind.

“i don’t mind, if it’s you.”
sukuna opens his eyes slowly, and smiles up at you. his poor sweetheart, sweating bullets because you’ve never killed a person before. even when you’re holding such a dangerous weapon, like he anticipated you would, you look so adorable.

“my love. do you have what it takes to kill a man?” he asks, before sitting up.
you don’t offer him an answer, only trembling as you stand before him. he smirks and gently takes your hand, the one that is holding the knife, and brings it closer to his own neck. so close, that the tip pricks his skin, and a small trickle of blood rolls down. your eyes widen.

“i don’t mind, if it’s you,” he repeats. 
“i don’t mind, if it means you’ll continue to think about me - for the rest of your life.”

your resolve, that had already been fragile, crumbles into a million pieces, the knife clattering against the floor along with it. you break into a hysterical sob, because you can’t-

sorrow, guilt, anguish… it all overwhelms you so much. but it only shows in the form of hics as you bury your face into your hands, not knowing what you should do anymore.

sukuna brings you into his arms and coos at you, with a composed smile on his face. wipes your tears away. he wasn’t lying when he said that he wouldn’t mind - but in the back of his head, he knew that you couldn’t. you cling to him so desperately, the wetness of your eyes staining his shirt, and it makes him wonder if you were the same person who had tried to kill him seconds ago.

you’re still weeping when he pulls you into a tender kiss, and he just can’t help himself when you’re being so cute, so defenseless for him. you can’t gather the strength to stop him (or are you purposefully letting him? you don’t know anymore.) as he lays you onto his bed and laces his fingers with yours, fervently kissing your neck this time.

you can feel how every touch of his causes your sanity to ebb away bit by bit, bringing you down into a dark abyss where you’re slowly starting to forget the faces of your friends and family. replacing them with only images of him. i hate him. i hate him. i hate him. (do you really? the way you sharply inhale when he brings his tongue to your nipple tells a different story.)

there is obvious conflict deeply rooted within your eyes, even when you kiss sukuna back, tugging his shirt up. you’re still crying, you never stopped since you started, and its beginning to give you a headache. you don’t want to think about anything. you want to stop thinking.

“of course. i can help you with that,” he purrs gently, pressing a kiss against your forehead again. were you saying your thoughts out loud? you didn’t even notice.

“there’s no need for you to think about anything, sweetheart. just let me make you feel good.”

its not long after when he slides his cock inside of you, with a soft groan. he treats you like you’re made of glass, and somehow, it feels so different from the first time he fucked you. he’s so warm, the warmest he’s ever been, whispering sweet nothings into your ear as his hips meet yours at a set rhythm that inches you closer towards your orgasm with every thrust.

sukuna’s exploring your mouth with his tongue, making it impossible for you to think about anything or anyone else, like he’d promised you. large hands roam around your body, and you swear you’d felt more than two of them at some point, all working to further taint your conscience. a familiar tightness coils within your abdomen.

lewd moans emerge from the pit of your throat, but they don’t get the chance to be clearly audible, as his lips are latched onto yours. when he pulls away to allow you to breathe, you catch sight of the blood that was still visible on his neck. you swipe a thumb over it. he bleeds. this man is human, just like you. it is hard to believe. sukuna’s eyes glint with interest at your gesture, and he proceeds to catch your wrist. your mind is in a haze from the intense pleasure of his cock brushing up against your plush walls, but you clearly watch as he licks his own blood off of your thumb, giving off a slight ticklish sensation, before leaning down to intertwine tongues with you again.

it coats your tastebuds and you can’t comprehend whether this disgusts you or thrills you. perhaps a bit of both. sukuna doesn’t stop, and keeps on kissing you until he is sure that you’ve savoured all of him.

“how do i taste? tell me, love,” he asks you, panting as he doesn’t stop fucking into you. his smile is lecherous as his cheeks burn with a red hue, terribly aroused by the idea of you relishing him.

“good… so good…” you mumble mindlessly. he draws out another breath and admires you with a twisted grin on his face.

“oh sweetheart…you have no idea…” he begins to say, but you fail to hear the rest. it falls into inaudible muttering. you wonder what it could’ve been. but thoughts get whisked away when he suddenly pushes gently onto your abdomen. you’re close.

sukuna puts his mouth against your shoulder, only to suckle on your skin. you rake your nails down his back in response.

and then, just like that, ryomen sukuna swallows you whole. your legs wrap around him, and you choke out a moan, back arching beautifully for him as he fills you up. mind and body, engulfed entirely with the very essence of his being. he feels a kind of satisfaction that travels beyond just physical as he looks down at the way your eyes roll to the back of your head.

this is sukuna’s love - from the very bottom of his heart.
