Chapter Text
The dancing light of the candles that dotted your room casted a comforting glow. Lit for ambiance, you laid on your bed pouring over your textbooks, studying. Rain pittered against the glass of your apartment reigning in the call of winter. The colder months meant more time spent inside and more time spent preparing for upcoming finals. The pains of stress and exhaustion seeped into your bones as the night went on. Focusing on the mythologies and folklore required for the ancient cultural history course you were taking usually excited you; however, tonight they bored you as you turned page after page of the old book. Sighing, you flipped through the chapter before stopping. A vivid picture caught your eye as you smoothed out the page with your fingertips. The figure on the page was colossal in stature, it looked human despite its multiple eyes, arms, and mouths. The detail was exquisite on the body itself, depicting bound muscle and striking black tattoos. You took a moment, partially recalling the lecture detailing how the entity was in fact a demon king an ancient cult worshiped centuries ago. The being was surrounded by devout followers, confirming your suspicious, all engaged in orgies and feasts.
In a way, he was handsome in a monstrous kind of way and the vivid detailing on the page didn't help as you pressed your thighs together. You sighed, unbelieving that an ancient drawing was apparently hot enough to turn you on. You haven't touched yourself in a bit, the much needed style of stress relief slipping your mind until you felt a bubbling inside you just now, encouraging on your thoughts as you gazed at the ancient art. Huffing into your pillow, you readjusted your comforter and pillow so it was nestled neatly between your thighs before you repositioned hips, pushing your underwear to the side. You sighed as your fingers pressed lightly against your pussy, taking into account how wet you already were as you glided over your folds. Fingertips dipping experimentally inside, you sighed as your thumb met your clit and rubbed slowly Biting your lip at the sensation you continued stifling little mewls.
The soft shirt covering breasts rose and fell with your breaths as you massaged them gently before you took it off. The small bars through the centers of each of your nipples glinted in the soft candlelight as you tweaked them occasionally. Sharp sensations of arousal thrummed through you, causing your lips to part in a silent moan and hump the pillow gently. Images passed through your head of hands on your body under dark red skies. Twitching against your touch you leaned further into your desire, circling faster. Another gasp echoed from your lips as your eyes fluttered slightly, clenching around your fingers while gazing at the image in front of you.
"Pleasuring yourself to my likenesses?" A deep voice reverberated against the thin walls of your room, as if the shadows were speaking. Startled, you snapped the book shut and your once busy hand darted to push yourself up.
"Oh, flattery can get you far but don't you dare rescind it..." He chuckled, a pair of pointed canine's appeared, glittering in the low light. "I'm going to absolutely devour you." The figure emerged, his face was covered in mysterious black markings, like tattoos. The candles in your room extinguished leaving only the moonlight pooling in through the window. As he stood the figures' extremely loose tunic slipped off his shoulders to reveal his massive physique and hung at his hips, only held up by a patterned sash. Stepping towards you, he took a seat on the corner of your bed jolting you slightly but you couldn't stop staring at the incubus. The tattoos continued down his body and were instantly recognizable; solid black lines that adorned his body like jewelry with some wrapping around the muscular limbs, others geometric lines that accent his chest and abdominal muscles.
"Who are you-?" you whispered, trying to maintain an air of calm but there was a small waver in your voice as you looked him in the face, gaze trailing on the fine tattoos that framed his eyes.
His jawline that could cut diamond shifted as a small smirk played on his lips, drawing a hand through his pinkish hair. His red irises gazed at you, "So you can see me..." he muttered
"Excuse me? W-what did you say?" You questioned, unsure what the significance was that you could see him.
He leans closer. An inky black claw makes contact with the soft skin of your cheek and traces your jawline. A subtle threat that could slice at any moment. "Something tells me you know who I am. My cult hasn't made a flesh offering in eons," He pondered aloud voice reverberating against your skin. "Today is the greatest day of your life for you have achieved your highest purpose, mortal." He rests his head against your shoulder and presses his face into your neck, inhaling deeply. "Hmmm definitely not a virgin, but you will do just as nicely."
"Excuse me did you just-?" Eyes wide at the insinuation that this sultry demon made about you.
"I'm not insulting you, morsel." he purrs into your ear. "It'll be a lot less painful for you if you know what the sensation is like." Pressing a kiss to your cheek before pulling away "A fine blood offering you'll be. I dislike going slow after all."
"An offering-? How-"
"You're the offering and I'm going to take you," he glowered. "And by that, I mean that I'm going to fuck you." His blackened fingers and sharp claws crept down your thigh, squeezing playfully before slotting against your underwear. Three fingers pressing against your pussy with the middle finger pressing against the wetness soaked between your lips. The pointed tip of his finger ghosting over your clit. Sukuna smiled, "You are wanting as well it seems... perfect. That's always welcome. Far more pleasurable for both of us, sweet creature." With a quick slice of his claws he ripped away your large shirt and panties.
His hands glide to your waist pressing you down into the soft comfort of your bed. Realizing what he was doing you squirm against his hold while his breath ghosts against your pussy. The sharp fingertips pressing v-shaped indents into the soft flesh of your hips, claws pricking you as a warning before his drool-covered tongue slipped in between your folds.
Mewling, you grasp the sheets beside you unsure if you were allowed to touch him while he held you down as he eats you out like a starved man, licking, nipping and biting at any flesh he can find. After a tentative moment you bring your hand down to his head, directing him as he found your throbbing clit and payed special attention to your touch. All while your other hand gripped the headboard for some sort of support.
"Now, do you like this?" He rumbled against you.
"Yes," you whisper before gasping at the feeling of his tongue running up and down your folds, sucking on your clit and lapping up all your juices from your past orgasm. "Oh f-fuck yes" you stuttered out. The stimulation making your mind feel hazy and in one swoop all of your thoughts were discarded, the only thing on your mind being the entity in front of you.
"Mhmmm you're so wet already... perfect for me. I haven't had anyone who tastes as sweet as you in ages. Like a..." he paused thinking for a moment about mortal food. "Cherry, yes.. a cherry! mhmmm," he groaned into you and continued.
"Th-thank you Sukuna." You hummed out, taken slightly by his kindness.
"Lord Sukuna. I will not be kind if you forget it." He muttered against your sopping wet coochie.
"Yes Lord Sukuna!" You whined out as he nibbled on your clit.
"Good girl... so obedient. Keep it up and you'll be rewarded."
Being too invested in pleasure to notice how you're rutting yourself against the curse's lips, you desperately chase after your high while squeezing your thighs together around his head. There's no way Sukuna could ever suffocate from two thighs constricting his head, but if there was ever the possibility, he would find it to be a great way to die.
"Oh! Lord! Sukuna- Sukuna!" his name paints your lips perfectly. He does his best to lap at everything you're giving, but he finds himself pulling away to gasp for air and chuckle to himself, catching that he's enjoying your taste a little too much.
"That's right, chant my name sweet thing. Chant the name of your god." He growls slickly into your skin. "You are so precious and delectable..." he punctuates the compliment by his tongue delving deeper inside you, greedily licking up your offering.
Sukuna's long tongue surrounded your clit and caressed it back and forth until fat tears of pleasure rolled down your cheeks and the grip on his hair remained tight. He slipped his fingers inside you, careful to retract his claws down to a smooth shape to not harm his new toy. His large fingers trace against your core before gliding against your sensitive walls and stretching you open. Pushing against soft muscle as his thick digits curled, eliciting a sultry moan from your lips.
His gaze was fixated at how his fingers coaxed slick from your pussy, drenching his palm. Moaning into his neck, you felt blush wash over you when you felt his red stare. You clenched and sucked him in, a sight he immediately loved. Your thighs parted more, giving him an even better view. "What a cute little pussy" He uttered softly, your head falling back into the pillows. That alone was enough to snap the tension building in your core. Your nails gripped his curls as you came, the lewd sounds echoing from his lips as he licked up every last drop until there was no tension left in your body.
His ragged breaths brushed against you as he pulls away, licking his lips and sighing. After a moment of peace Sukuna placed a kiss on your clit, "You make such pretty noises. I want to hear you sing more for me."
Nodding in a lust-addled stupor you nodded, smiling softly. He took you in his arms and moved you to straddle his massive physique. You felt something big move underneath you. Out of the corner of your eye you saw what could only have been a mouth part from his stomach. It was complete with soft lips, a dripping demonesque tongue and, of course, a set of sharp teeth. Suppressing the urge to scream, all you could do was stare below at the tongue lolling out beneath your dripping, plump pussy. After a moment you felt the tongue flick up voraciously, swiping a stripe up the center of your pelvis before plunging into the softness of your folds. Sukuna brought a hand down to your ass caressing the plump flesh and feeling the tongue press against your holes, eating you out sloppily. You felt his tongue flick voraciously over the rim of your asshole, your body tensing then relaxing at the sensation.
"Are you practiced with this morsel? You're relaxing where some would recoil..." he hummed as his palms held you up.
"Mhmmm," you moan into his mouth as his tongue snakes against your lower lip "s'good lord Sukuna- feels good."
"Mhmmm, good girl." Sukuna moaned as he felt your body tense and relax as he prepped you. He cooed lovingly at your body, tracing it with a pair of hands as he watched every expression flitter across your face as he ate you out.
"Your body is so supple and beautiful...The piercings are a good touch." He hummed against your neck before his palms enveloped your breast. The mouths that emerged licked and suckled softly on your nipples. Your moan was cut off in surprise as another one of his hands snaked around your neck. His gaze captured your debauched countenance and watched your lips fall open, your eyes roll in enjoyment, body trembling trying to peak.
But Sukuna wanted to be a little cruel.
He stopped at the dawn of your climax, a wicked grin snarling his features as you realized what he had done. Whines begin to pour from your lips as your thighs clasp around his body, grinding down desperately to finish. You looked at him, tears pooling in your eyes, wetting your lashes, and your lips pressed together in a plump pout which he attempted to ignore.
Playing with your orgasm he pressed so softly against your clit, ripping a desperate whine from you, "Beg for it." His hand eased and he started over slowly, the tips of his fingers pressing against the swollen bundle of nerves over and over.
The pain from having to hold back as Sukuna teasingly slowed and toyed with you was agonizing. "Lord Sukuna- please-!" Your voice sounded soft and sobbing, moans delicious, as he pulled two fingers down your slit and brought them onto his lips. His long tongue lapped down the length, tasting the essence of you coating him. "Please... I beg you! Let me-let me cum again for you-" You sniffed as you pressed your thighs together, trying to find some sense of relief from what he had built up inside you.
He tsked and cupped your face in his palm, taking in the look of wanting as his claws brushed dangerously against your cheeks.
"You're whimpering like a slut for me already... do you want it? Do you think you can take all of me in that cunt, sweetheart?" Sukuna gave his fingers another long lick as of to savor it.
"Huhuh, please! I want to feel you- I need to feel you inside me, fill me-" he leaned down and shoved his fingers past your plump lips. He slid them deeper, causing drool to coalesce on his fingers. You could taste yourself on his digits. A hot feeling of lust and humiliation humming through you, but a newly awakened part in you were enjoying every second of it.
"Mhmm, and what about that ass? I can fill both up at once if you'd like, sweet thing." He hummed, the hands still present on your breasts grasping handfuls of your soft flesh. You moaned around his fingers until he pulled them out, opting to grab your ass to play with your plump cheeks.
"Yes!" You let out as soon as his fingers left your mouth, a dribble of saliva falling from your lips.
Sukuna shifted out of his loose-fitting robe, letting the silk pool on the bed before returning to pump his twin cocks in a closed fist. His tongue slipped behind his teeth with a lick as he grinned, seeing the look of shock wash over your face.
You realized what Lord Sukuna meant when he said he could fill both holes at once.
Both of his cocks looked absolutely gorgeous, each at around 8-9 inches with a girth that made your thighs press together and tremble at what the stretch would leave you looking like the next morning. Each was slightly pale and carried a bright blush that cascaded down the tips. The heads were a dusty pink with a needy shine of precum clinging to the mushroom-shaped tips. Blueish veins ran up the shafts, thick and a bruised blue against the pinkish hue but were slightly marked by the intricate geometric tattoos that dotted both the base and the heads. The sight alone almost let more drool slip from your mouth.
"Want me to ruin you? You like it a little rough don't you, beautiful?" His deep voice reverberated against your soul. That alone could bring you to the edge, even twitching at the thought before he withdrew his fingers and pressed a kiss against your lips.
You hummed at the warm sensation, "Please do."
"You want to cum on my cocks, right pretty thing?" he hummed picking you up and placing you on his lap, your legs over his shoulders.
"Yes... yes!! P-please let me..."
His arms holding you close and legs tightening around him, hungry for him. He smirked, hands squeezing the back of your knees, pushing your thighs until they barely grazed your chest. The sight of your bare sex dripping and swollen with need, glinting in the red light tempted him more than anything he could remember.
"Good girl. Look at you being so obedient..." He growled, nipping your throat before soothing it with a kiss.
"I-I, they're- going to fit?" your voice was weak as you whimpered, feeling your nervous tears gathering at the corner of your eyes when he nudged at your pussy. The head of his cock teased over your entrance, rolling his hips and collecting slick before nudging the head again over your sensitive clit.
"We'll go one at a time, sweet creature. I'm not going to break you as soon as I finally have you." He hums, pulling you close. Despite the kindness in his words you hissed when he pushed his tip in. He let out a wolfish chuckle when your body shuddered, "It seems like it'll fit just fine, you're drooling all over me sweetheart."
"No, huh...gentle" tears pushed down your cheeks when you looked up at his towering figure, "I've never had anything this big. I-"
The king of curses halted his movements. Your eyes widened when a wide grin split on Sukuna's face and a dark haze formed over his sharp eyes.
"You've never had anything this big? Is that right, morsel? " he repeated mockingly, staring at your watery eyes when he pulled his tip out of you, "I see how this is..." he flipped you over onto your back, pinning you to the mattress. You yelped when he suddenly pushed your knees all the way back until it was right against your chest. The pain at the sides of your thighs had you slamming your head back, arching yourself off the mattress as Sukuna licked his lips at the sight of your dripping cunt.
"Oh... you are so wanting because no one has ever truly fucked you before..." he mused, gripping you by the back of your knees as he repositioned himself.
A sharp mewl ripped from the back of your throat when he pushed the head in, not even halfway through but your hands were already clawing at the sheets beneath you at the stretch. Your walls clamped down at the newfound fullness, stretching apart by a girth you had never experienced before. Your moans were positively sinful as they flooded the room. You skin felt burning hot to the touch and it brought him such arousal as he began rocking slowly into you.
His cock pulsed in you when he laughed, his lips curling up at the way your toes pointed straight and how your eyes rolled back. "This big?"
You could only whimper when he pushed more of his cock inside. "How about this, morsel?" he asked again, his throat bobbing when your tight walls fluttered around him. Your hands quickly moved up to grip the muscle of his back.
More. "How about this big?" The laugh rumbled out from the bottom of his chest when your voice came out high pitched and broken. The painful hiss stuck at the back of your throat when he gave one final push, his heavy balls and other cock slapping against your ass when he finally bottomed out. Squirming and whimpering, sweat dampening your neck, panting as you slowly get used to the girth and he simply smirks and watches you with the lingering fear of what might happen if you disappoint him. Your body treading between the line of pain and pleasure as your vision faded white around the edges from getting stretched. He was hot inside of you, and the weight of his cock sitting inside of you was impossible to ignore as every cell in your body was set aflame by a lusty need to feel him move.
"Let me show you how a king fucks his new queen." He growled, rolling his hips slowly while grabbing your hair as he rhythmically grinded into you. The sudden rush of pleasure flushed through your body, exponentially rising as he slid in deeper and effortlessly after you adjusted to his size. Sukuna groaned, his third hand latching onto the base of your throat as he felt you clenching around him, coupled with your twitching and moaning incoherent words at his gentle thrusts.
He let out a soft moan, loving the feeling of you around him; the way he can hear the beating of your heart, the way that you're nearly stretched to your breaking point, the tremble in your thighs - the slight bulge in your stomach where he's big enough to distend you. He smiled, running one of his claws over that bulge and delighting in the beautiful way that you moan and clench around him.
"You feel, oh you feel so fucking good." Sukuna purred, running his hands up your sides and squeezing playfully. "Look how lovely I look inside of you," he murmurs. "Almost like you were made to take my cock, isn't it?" He says this as if you're not aching from the stretch, following the statement with a wicked smile. The red irises of his four eyes glinted; "I think we could fit both of them inside of you now, don't you?"
Taking a deep breath you stilled, adjusting to his entirety before taking another one. In the moment of pause you felt his stomach tongue come up and caress your pussy. The new sensation of the tongue pressing against his sheathed cock making him jolt slightly.
Sukuna fingers squeeze the flesh of your thighs reassuringly as he slowly began pushing in and out of you, "Such a pretty and strong treasure for me, aren't you?"
His words turn you on even more, you feel your arousal growing. You squirm under him responding to his thrusts, "Don't squirm too much," he growls at feeling you get tighter around his cock. "So eager to be ruined by me. Such a good girl," he hisses into your neck, covering his moans by sucking hickeys onto your sensitive skin and down your shoulder.
"Fuck-" he let out quietly, growling in pleasure as you clenched around him.
You felt your slick drip down onto his shaft as he slowly ground into your pussy.
"Ah-okay- okay." You sighed out.
"Here morsel," he repositioned your hips before teasing your ass with the head of his second cock. Sukuna grabbed it in his free hand, the mouth opening and slicking the length with drool as he eased it against you. "There, now- oh- fuck" he grunted, easing himself in gently.
You let out a whine at the stretch, breathing steadily as the head pressed inside before the discomfort slowly took on a more pleasurable quality. Rolling you hips slightly you felt him press deeper inside you, pulling moans from the both of you.
"Mhmm, I'm not even halfway in yet and you feel so deliciously tight. He hummed, caressing your ass until it finally met the meat of his thighs.
A sinful moan left your lips as you felt the twin cocks press against each other inside you, pressing against the thin walls. Letting you get use to the feeling, despite being stretched out around the inhuman girth and length of both of the shafts inside you.
You felt his breath in your neck and his groans muffled against you, arms cradling you protectively. "You're so lovely-" he looked down at you, his red scleras tinged with gold.
"Stop-stop looking at me..." you mumbled shyly.
"I'm going to look at you." He answered, caressing your waist.
"You're looking at me like you... like you love me."
"Does that bother you, sweet thing?"
"I- I don't want to like it," you met his gaze, his clawed finger tilting your chin up.
"It'll be more fun if you do. Besides, why do you think I'm looking at you like this? It's because I want to, youre beautiful and feel gorgeous." To punctuate his statement he pressed a kiss to your lips, chaste, before he felt your tongue trace his lower lip. Sighing into his embrace you deepened the kiss. "You're mine, no one will ever have you."
You felt his tongue flicked and suck against your neck, his moans muffling into your soft skin as his thick shaft was sucked deeper inside you, milking his cock every time he pulled out. Sukuna palmed your lower abdomen, feeling himself fucking so deep, he smirked at the sight. A well of pride cresting in his chest as he grunted louder. Crimson eyes stared into yours; eyes teary, cheeks blushing, lips swollen from your own bite, parted for some moment for another moan. All for him, only for him to see, only for him to devour.
"I will devote myself to you as you devote yourself to me." After a moment he brought his hands up to your breasts, caressing them before you felt the mouths on his palms softly envelop your nipples, licking and biting at them. Causing you to arch up into him. He brought another hand under your arched waist, holding you close. "Good girl. My girl." His body pressed against yours, heavy and muscular as Sukuna was hulking compared to you. You squirmed when his tongue licked over your neck. "I will always be apart of you... Not that you have a choice, morsel. I could make you my queen if I wanted to."
"You-you could do that?" You questioned before hiccuping through a moan.
"Only for a creature as sweet as yourself, look-"
In that instant your vision clouded and revealed what could only be a reflection of yourself. Your neck was adorned with precious stones and pearls that cascaded down to sway against your breasts which highlighting their shape and how they swayed with every movement. Your hips were covered in scarlet and purple silks held up by golden facets. Golden earrings and multiple piercings dangled from your ears and jeweled chains dangled from your pierced nipples that continued and disappeared underneath the silks as a body chain. A circlet of gold that was hand-braided into your hair was the tell-tale sign of an ancient queen. That, coupled with the subtle black tattoos that delicately accented your joints and face in a near-match to Sukuna's.
"A queen of curses for me. A king of curses for you." Sukuna purred into your ear, snapping his fingers and bringing you back to reality, away from the awe striking vision.
"Oh- " you moaned him hitting even deeper, closer to ecstasy "Y-yes. Yes."
"Oh? Interesting now. I really could you know, you'd be by my side of eternity. I'd prize you like the most coveted treasure." He purred.
That was all he needed to firmly grasp onto your waist and pull you back onto his cocks, thrusting fast and hard. The skin slapping sound which you had been subtly craving filled the room. Your knuckles turn white as you grasp onto Sukuna's muscled back tightly, scratch marks dragging down his tattooed flesh. "Sukuna, Lord Sukuna! Yes please, take me" you began.
"Let me hear you, my queen, who do you belong to?" His grip was strong, making your breath hitched as the feeling in your stomach was beginning to build up. You were practically soaking his thighs. The lascivious sound of skins coated with arousal clapping onto each other, echoing against the walls.
His balls, thick and full, were placed perfectly as they slapped heavily against your ass.
"You... I belong to you, Sukuna! Only you!"
You repeated the last two words like a mantra loudly, devoutly. Smiling, Sukuna's hands spread you open, delighting in seeing his cock disappeared into you and the creaminess forming in the base, a highlight of your own pleasure.
In a moment his tattoo markings slowly seep onto and become apart your flesh, like ink through water. The rhythm and purrs he sets create a sort of trance as the seal forms. The black ink of the tattoos turns white before seeping and disappearing into your flesh. You're brought back to earth by a tap of a lacquered claw he purrs in your ear; "Keep your eyes on me, little queen."
Loud slaps echoed in the room when he started thrusting, holding your shaking legs tight as he pounded into your cunt with feverish intent. The crescent marks of his nails digging into your skin was painful, and your body did not feel like it was under your own control as he drilled in and out of your sloppy hole. Your ass jiggled under each slap of his thighs against your cheeks, everywhere his cock had dragged against feeling like it was set on fire as he fucked you at a frantic pace. Your mouth parted when the initial pain was taken over by an undeniable lust, your brain melting into mush with his cock bottoming out in your so hard you could not even think straight
"Cum again, for me." He purred against your skin.
Something about his cocks stretching you open, the feeling of them gliding against each other through the soft separation of skin caused you to pant; nearly overwhelmed with the girth and the feeling of being stuffed full. You came again, clenching and twitching as a red light took over your vision for a split second.
"I bet you have men and women by the throat and killing each other to have a taste of your body, I certainly would." he murmured appreciatively, nibbling at the sensitive skin of your neck as he dragged his teeth down. He thrusted languidly, "A woman like you would love that I bet, all that attention from people killing for a chance to fill you up with tongue and cock."
"I want m-more!" you sob, your body hyper-aware of how fast he was pounding into you.
In an inhuman display of strength, Sukuna hoisted you up to face him and used his other two arms to position you onto his dick. "Don't worry my treasure, I'm going to stuff you so full that you leak for hours- I'll give you everything fuck-"
Two of the curses other muscular hands played with your pierced nipples, twisting and running over them with his index finger and thumb, flicking over them. "Look at you" Sukuna hummed, his hips grinding further, harder into your ass, and you keened at how the shafts moved together inside you. "So needy, so mhmmmm... greedy for everything that I'm giving you." His vulgar words and the way he praises you make you blush, "so pretty when you blush" he says as he caresses your cheek.
Tears of overwhelming pleasure ran down your cheeks as his hands trailed down your body holding you close as his thrusts sped up.
"You look so pretty with those tears running down your cheeks," he rasped greedily as he grabbed a handful of your tits as he impales you deeper onto his cocks, "Or maybe I'm a bit of a sadist." He chuckled, going harder when the wetness of his tongue tasted and licked away the salty droplets. You whimpered. "So pretty when you devote yourself to me," he said before rutting his hips against your pelvis, one pair holding onto your breasts while the other gripped your hips. Sukuna's claws pressed V-shaped imprints onto your flesh as he grinded his hips into you causing his cock to surge deeper into your core. "A gorgeous queen." His warm breath brushing against your cheek as he accentuated each word with a roll of his hips.
"Sukuna please, I'm gonna cum- I'm gonna I'm again-" you moan planting your nails along his back, he grabs your wrists and holds them above your head with one hand.
"You look so beautiful taking my cocks" he chuckles increasing the thrust of his hips grasping at your waist and pulling you into him. With no mercy his thumb caresses over your swollen bud of nerves, lighting up your sensitivity and causing your body to jolt from pleasure. "Yes! Just like that baby" he praises as your orgasm shuts down your brain and makes a mess of you.
"Yes yes yes yes- fuck yes, don't stop, please don't stop-" you practically scream out as he prolongs your orgasm into an everlasting peak.
Sukuna cackled, voice reverberating off the walls of the mortal plane and kissed you deeply. Your head dips forward so your forehead presses against his, arms falling to rest around his neck, thighs squeezing his sides, hips jerking in an uneven rhythm as you ride out your orgasm. He continues to thrust up into you, hard, cursing as he loses himself in the spasming of your tight cunt. His hands jerk your hips down one more time, slamming you onto his shaft as it pulses, sheathing himself fully inside you as his balls empty into your wet heat and paint your walls white. He hisses as his cum spills into you, filling you, and his firm grasp on your hips makes sure you stay there and take all of it. He kept his thrusts going, drunk on the sight and feeling of your pussy. You whined at the warmth that filled you up, the stickiness leaking out with each push of his fat cock out of your holes and running down where your bodies connected. Sukuna leaned his body back as he slowed down, his eyes gluing onto the mess between your legs as your juices mixed with his release dripping onto the sheets. He pulled you into a warm embrace, pressing a searing kiss against your lips as you clung to his body. With your breaths in sync he whispered sweet praises in your ear. Your hands trailed over his still-hot body as you quickly fell asleep in his arms.
When you woke up the next morning your bed felt warmer as you snuggled into the sheets. Before the remembrance of the night before cracked over you like lightning. Bolting upright and looking around the room nothing was out of the ordinary or showed even a sense that Sukuna had appeared at all. That was, until you looked into the bathroom mirror to see a canvas of dark marks blossoming on your skin. Uniquely some showed the presence of his sharp canines. As you turned to shut the door to inspect them more closely, out of the corner of your eye you thought you saw a glimpse of black ink appear in your skin before quickly vanishing along with the mural of bruises on your flesh.
