You’re straddling him, lowering yourself onto his cock the way he lets you, whining because he’s too big. Your perfectly manicured fingers dig into Sukuna’s chest, leaving faint pink trails across his tan, tattooed skin.
“Come on, doll… take me deeper.”
Sukuna’s cock is huge. Thick. Heavy.
Veins tense beneath your fingers. The flushed tip, slick with your arousal, glistening with pre-cum, stretches you open as it pushes deeper in — and the sensation makes your vision go dark at the edges.
You’re naked, except for the gold chain with a diamond around your neck — your father’s gift for your coming of age — and it looks wildly out of place against the rumpled sheets, in the smell of sweat and sex...
Sukuna is sprawled against the pillows, one arm tucked behind his head, watching your attempts to sink down onto his cock with a lazy, mean smirk. Amused.
He doesn’t even help.
Just watches you struggle to take him.
“Can’t even handle the tip, little doll?”
You tighten around him, your walls clenching, and he growls in satisfaction, like he’s not sure whether it’s pleasure or irritation.
You don’t belong here.
And Sukuna knows it.
Your world is private drivers, daddy’s money, designer boutiques, and etiquette lessons.
His is frat parties, weed, casual hookups, and constant trouble.
You can’t even drink properly.
You’ve never thrown up from alcohol. Never known a hangover.
You’ve never smoked weed.
Never been fucked in the backseat of some filthy, smoke-filled car.
You’ve obviously never wrapped your lips around someone’s dick just to make them come.
Clean and untouched.
Too polished. Too perfect.
Like something meant to sit pretty, not take him.
And it fucking pisses him off.
And now you’re so stubbornly trying to prove to him you’re no worse than the rest.
“Poor sweet thing,” Sukuna purrs now, his low voice vibrating down your spine.
And still, you kept coming back to him with those naive eyes — like he could be your boyfriend.
It all started strangely. Spontaneously.
You’ve always been his clingy little fan...
Back then, you’d clung to his arm with a death grip, standing by the staircase, like you belonged there. Like you belonged to him. You’d scared off some random brunette in a cheap top who could drink — and probably fuck — way better than you.
Sukuna had reacted sharply.
He’d torn his arm out of your grip, jaw tight, eyes cold.
“You want my dick? Yeah? That’s why you pulled this whole circus?”
You — with your trembling lips, perfect curls, and a short dress that probably cost more (before Sukuna tore it) than he spent in a month — looked painfully out of place down there.
“If I fuck you, will you finally leave me alone?”
He’d said it back then, like you were something to brush off.
“Listen, doll. Even if I agreed — you wouldn’t manage,” he hissed, leaning close to your ear, gripping your elbow tight. “Your pussy’s probably as spoiled as you are. Wouldn’t even take half of me. You’d whine and cry like you are now. So get lost and stop bothering me.”
He’d expected you to cry and run.
Instead, you lifted your chin stubbornly and said:
“You’re wrong. I can.”
Idiot. You’re so stupid. Such a stubborn girl.
But.. How long ago was that? An hour? Two?
His words still burn somewhere under your ribs.
Sukuna watches your brows draw together, the way you bite your glossy lips — your expensive lipstick long smeared — while you stubbornly try to take his cock with your tight pussy.
Brat.
So soft. So weak.
Pretty little doll.
Made to be handled.
Only when Sukuna mutters again about how useless you are do you flinch and remember to move.
“Look, little doll,” Sukuna nods downward mockingly. “Your poor pussy can’t even take half. And you thought you could handle it?”
You flush, but don’t look away.
You’re looking down at him, thinking about how beautiful Sukuna is. Dizzyingly so. The kind that makes your knees weak and your chest ache.
The tattoos you want to trace for hours.
Those cruel eyes that are still, to you, the best in the world...
“That girl downstairs,” he continues lazily, stroking your hips, “she would’ve managed. But you…” He sighs dramatically, pretending disappointment, starting to lift you off him. “Get up, baby.”
Off him. Off his cock.
“This is pointless.”
The anger hits instantly, burning up your throat.
You shove him hard in the chest, forcing him back into the mattress. Something like real interest flickers in his eyes when you squeeze them shut, grit your teeth — and drop your hips down sharply instead of moving away.
Sukuna curses under his breath when you force yourself a little lower onto him.
The smirk slips.
Just for a second.
And something sharper replaces it.
Interest.
You’ve taken almost half of his cock.
“Fuck,” Sukuna breathes through his teeth, sweat already forming on his brow. The smirk slips off his face, replaced by something hungrier. “Why the hell is your pussy so tight, brat? Has anyone ever fucked you before?”
You try to lift yourself, to give yourself a break, but his fingers instantly dig into your hips, stopping you.
“Where?” his voice drops, darker now. “Where do you think you're going, doll? You barely even started — and you're already giving up?”
“Kuna, wait…” you whimper, looking down at him with wet eyes.
A scared, stupid brat who wanted too much and can’t handle it now — that’s what you are.
And he’s going to teach you.
“Nah,” Sukuna smirks.
He suddenly pulls you down again, forcing you back onto him. You cry out, digging your nails into his shoulders.
“Begging time’s over, sweet thing. A deal’s a deal. Especially after you scared off that brunette…”
Sukuna starts pulling you down slowly, and you feel his cock, hot and pulsing, stretching you open as it sinks deeper. Every inch twists low in your stomach.
You hear the wet sound of him sliding into you.
When Sukuna is fully inside, you feel the head press deep within. A thin, broken sound slips out of you.
He freezes for a second.
“Shit,” he breathes, glancing down. He can see it bulging against your belly. “Look. See that, brat? And you were whining.”
You mumble something, shifting your hips.
“Don’t cry,” Sukuna clicks his tongue, something like satisfaction slipping into his voice.
His hand slides over your thighs.
“Poor thing,” he coos, watching your long, doll-like lashes, wet with tears. “So sweet. So dumb. Why’d you latch onto me?”
He smacks your ass.
The sound is loud and wet.
You flinch, sobbing.
“Sweet little doll,” Sukuna smirks.
You wipe your tears and catch yourself almost smiling. Sukuna grimaces slightly, realizing you really might be that stupid… or maybe his cock has already knocked the sense out of you.
He lifts you by the hips.
Thinking he’s letting you up, you try to get up, but he chuckles and drops you right back down.
“You wanted this so badly,” Sukuna reminds you, making a lazy thrust from below.
He thrusts again, harder.
“Stubborn brat,” he mutters through clenched teeth. “But I’ll admit — your pussy is… fuck. Good. Greedy as hell…”
Greedy just like you.
“Go on,” Sukuna orders, leaning back against the pillows. “Bounce, doll. Ride me. Show me how badly you wanted this. Prove I’m not wasting my time on you.”
You look at him, dazed.
Your eyes are hazy with arousal, pupils blown wide.
“What? Too much for you? Overestimated yourself?” Sukuna mocks, twisting his mouth in fake pity. “Can’t handle it, brat? Too much work for a rich girl? Not used to doing things yourself?”
You frown, swallow, brace your hands against his chest and start moving.
Slow. Clumsy.
You lift your hips, feeling him slip out, then sink back down.
Each time a little better.
Sukuna only helps slightly, guiding your hips, setting the rhythm.
Your wet, slick pussy makes soft, wet sounds every time you sink down. You feel his cock rub against your front wall, brushing against something impossibly sensitive inside.
You whine, moan, biting your finger to keep from crying out.
“Good,” Sukuna breathes, watching.
His gaze drifts over your body — your tense stomach, your trembling breasts, the gold chain swaying between them.
He reaches for it, wrapping it around his fist.
“Come here,” he tugs the chain, pulling you toward him.
You cry out, nearly collapsing onto his chest, and the movement almost pulls his cock out of you. You clamp down around him instinctively.
Your faces are inches apart.
Yours — stunned, tear-streaked.
His — dark, thoughtful.
Your pussy pulses when you notice he’s staring at your lips, but Sukuna growls softly:
“The hell did you stop for?” his breath burns against your mouth.
You whine and start moving again.
Small, fast.
Grinding your clit against his pelvis.
Your mouth falls open, drool slipping from your chin.
And Sukuna just keeps watching.
“Not bad,” he finally admits. “You’re learning.”
A drunk, happy smile spreads across your face — and dies instantly.
Sukuna yanks the chain again, pulling you back close.
“Wipe that expression off,” he growls, grabbing your cheeks with his free hand, forcing your lips together. “Too early to be proud. Move.”
You obey.
A few more rolls of your hips and that tight knot starts twisting inside you.
“Kuna…” you gasp. “I… I’m gonna…”
“Already?” he scoffs. “On a cock you could barely take? Go on, sweet thing. Show me what you can do.”
And that pushes you further. Your walls tighten in a rhythmic pulse. The sensation crashes over you, overwhelming you completely.
You hear his rough exhale:
“Just like that. Your tight little pussy squeezes so well. Keep going, baby, milk me.”
You almost black out when you come again.
Your pussy pulses, tightens around him, squeezes, sucks, and every spasm shoots up your spine in a sweet, exhausting tremor...
And in that moment Sukuna suddenly sits up, pulling his knees in. Sharply, he shoves your shoulders and you fall onto your back.
He hovers over you easily, grunts, and thrusts back into you in one powerful motion, burying himself all the way in.
His balls slap against your ass.
You arch, gasping for air.
He grabs you under the knees, lifting your legs so high they almost touch your chest, folding you in half.
He pulls out and pushes back in again, starting to fuck your already oversensitive pussy.
Fast, rough, deep.
Wet sounds fill the room.
You see his cock disappear into your body and slide back out again, slick with white foam.
“Enough…” you whine, trying to crawl away. “Kuna, please… slower… I can’t…”
You hate yourself for begging.
You know what brand of cigarettes he smokes.
You know his best friend’s name.
You know which days he goes out and which he doesn’t.
You know everything about him because you spent six months watching him on social media, liking every photo and taking screenshots to look at before bed…
“You can, brat,” Sukuna exhales between thrusts, watching your pussy with a satisfied, tense smirk. “Thought I’d go easy on you?”
Sukuna hovers over you, pounding into you.
You feel every inch of him — the way he enters, stretching your walls, the way the head presses deep into you.
He pulls out almost completely, only the tip left inside, and you whine at the loss — then he drives back in, sharp, deep, to the hilt, and your body arches on its own.
His hips slap against your ass with wet, heavy sounds, and with every thrust more slick leaks out onto the sheets.
You feel how soaked it is down there, how sticky and hot, how his heavy balls slap against your core with every movement.
“Hear yourself?” he breathes, voice hoarse, rough, breaking. “Hear how your pussy sounds? How it’s begging for more?”
Sukuna leans down, grabbing your chin and turning your face toward him. His rough fingers squeeze your cheeks, forcing your lips into a pout as you look up at him with a hazy stare.
“Pretty face, sweet thing,” he smirks. “You’re so sweet, so dirty right now. You like it, huh? Like being fucked like this?”
You try to answer, but only a strained moan escapes.
Sukuna pushes especially deep and your eyes roll back.
“What?” he slows, painfully slow, almost pulling out before pushing back in by a fraction. “I can’t hear you, little doll. You like it?”
His cock pulses inside you.
“Y-yes…” you manage. “I like it…”
“Good girl,” he exhales, satisfied, and slams back into you fully, making you cry out.
His fingers dig into your hips, leaving bruises, his teeth sink into your neck, biting, leaving marks. He suddenly pulls out completely and flips you over — by your hip, by your shoulder, without any care — and you end up on all fours, face in the pillow, ass up.
“Better,” Sukuna growls, and his palm smacks your ass hard.
A sharp gasp leaves you.
Heat blooms instantly across your skin.
He spreads your cheeks with his fingers, looking at what he’s done.
Your pussy — swollen, flushed, wet.
He watches with a satisfied, predatory smirk.
“My sweet girl’s dripping.”
He spits right onto your pussy.
“Needy cunt,” he mutters, spreading the spit over your lips with his fingers.
Sukuna pushes back into you — from behind, deep, all at once.
You cry out, gripping the pillow as he fills you again. His hand reaches forward, grabbing your hair and pulling your head back, forcing your back to arch.
“I’ll ruin you,” he hisses.
He fucks you hard, deep, his balls hitting your clit with every thrust.
One hand holds your hair, the other reaches for your chest, squeezing, kneading, rubbing your nipples until you moan louder.
“Like being my dirty little whore?” he growls into your ear, driving in so hard you squeak.
“Y-yes…” you breathe, drool slipping down your chin. “Yes, Kuna…”
The words reach you with a delay, like you're hearing him through water.
“Whore.”
Such a bad word.
Your nanny would’ve slapped your lips if she heard it. But when Sukuna says it… it sounds like a compliment.
Like the best praise in the world.
You want to say something smart, prove you're not just a whore but… but what?
You freeze for a second, drifting inside yourself.
Sukuna smacks your ass again — hard, leaving a red mark. Then again. And again. A low moan slips out each time, but instead of pulling away, you push back against him, taking him deeper.
“Greedy,” he smirks. “Not enough for you? Want more?”
“More…” you moan.
He pulls out, and you whine at the loss. But he immediately pushes you forward — chest to the bed, ass up — and you end up sprawled out, legs spread, your wet pussy open for him.
He slides back in and you moan into the pillow.
His fingers play with your clit, rubbing, pressing, making you arch and cry out. You come again — sharp and intense — squeezing his heavy cock. Your walls clamp down in a frantic rhythm, and Sukuna growls, feeling his own orgasm building as your hips twitch.
“Where?” Sukuna growls. “Take it, doll. You wanted this. Take all of it, brat.”
And then the heat crashes over you.
Hot spurts fill you deep inside.
You feel his cock twitching, spilling everything he has into you, excess already starting to leak out, mixing with your slick and dripping down onto the sheets.
He comes hard, long, growling, pressing you against him so tightly you can feel his body trembling with tension.
When he’s done, he slowly pulls out, and you feel warm, thick fluid immediately starting to spill from you.
You lie there, unable to move, feeling his cum leak out, drip onto the bed, slide down your thighs, mixing with sweat and saliva.
Sukuna leans back, breathing heavily, watching you.
Your exhausted body.
Your ass still flushed from his slaps, bruises already forming on your hips from his grip.
You’re soaked, sticky, smelling like sex and him.
He smirks, satisfied, running a hand over your ass, squeezing, feeling your muscles still twitch.
“Well?” he chuckles, brushing damp hair from your face. “Proved what you wanted? Happy now?”
You try to answer, but only a tired breath escapes.
You feel your strength draining away, your eyes growing heavy.
You just want to lie there and melt.
But a thought appears — you should get up. Go to the bathroom. Clean yourself up.
You start to push yourself up on your elbows, trying to gather enough strength to at least crawl to the door. You shift, trying to get on all fours — but the moment you move, his hand presses against your lower back and shoves you down again.
You fall chest-first onto the bed, ass up, crying out in surprise.
“Where do you think you’re going?” Sukuna asks lazily, almost disappointed.
You turn your head to look at him over your shoulder.
He’s sitting against the wall, sprawled out.
“I… I thought…” you mumble, trying to lift yourself again.
“You thought,” he mocks. His hand pushes you down again, holding you against the mattress. “You’re too dumb for that, little doll. Who said I was done?”
He slaps your ass.
You yelp, twitching, and he just laughs.
You try to gather your thoughts, but they slip away like his cum down your thighs.
Some stupid, stubborn thought lingers in your head.
You frown, trying to remember…
“Stay,” Sukuna orders. “I didn’t let you go.”
He spreads your cheeks with his fingers, looking at what he’s done. Your pussy — swollen, flushed, still leaking his cum.
He takes his cock — still hard, still ready — and runs the tip along your folds, spreading spit and cum, pressing against your clit, teasing.
“See?” he whispers. “It still wants you. And you were trying to leave. Where?”
“Kuna…” you moan as the tip slides over your clit, sparks bursting behind your eyes. “I can’t anymore…”
“You can,” he taps his cock against your pussy — once, twice, three times.
The sound is wet, filthy, and you flinch each time.
“Hear that? She’s asking for more. Your pussy wants it. Don’t lie to me.”
He pushes just the tip in — then pulls out again, teasing.
You whine, pushing back, trying to take him, but he pulls away with a smirk.
“Not so fast, little doll.”
You don’t even argue. You can’t.
Arguments require a brain and yours is somewhere far away.
You just go limp, pressing your face into the pillow. No thoughts. Just a heavy, pleasant emptiness in your head and a deep, pulsing warmth between your legs.
You feel his fingers playing with you again and instead of fear or protest, you simply close your eyes, satisfied.
Sukuna says something else, but you’re too stupidly in love to remember what it was.
You just curl your lips into a soft, dazed smile and wait for him to make you feel good again.
That’s why you’re here, right? Or is it something else? Doesn’t matter.
You’ll think about it later.
If you still remember how.
If you still remember how to think without him.
If you still want a touch of sadness, read this line:
“I love you,” you whisper into the pillow so quietly Sukuna won’t hear. Because if he hears — he’ll send you away. And if he sends you away, you’ll die.
