Sukuna could count on his hands the number of times in his life he’d been nervous. Once, when he was the ring bearer for his older brother’s wedding. The two gold bands sat on top of a red cushion and probably cost more than anything Sukuna had ever held before, and he spent the whole time thinking how much of an idiot his brother was trusting him to walk down the aisle without majorly fucking something up. The second time would have been when Yuji was born, and Jin brought him home from the hospital. Small, frail, and pale, with the signature pink tufts of hair and the softest look on his face, his big grey eyes unscathed, full of curiosity. Jin asked if he wanted to hold him, and Sukuna protested, having never held anything so gentle at such a destructive time in his life. Jin insisted and handed the bundle over carefully, with Sukuna clutching the baby close to his chest, not even breathing in fear of disturbing Yuji’s peaceful slumber.
The third time? Probably now, when you, staring at him with sultry eyes that stopped him in his tracks, walked backward into your apartment with an invitation that he was ready to beg for on his hands and knees weeks ago, with your last line hitting him like bricks to the chest.
Why don’t you come inside and find out?
He nodded dumbly, his mind wiped clear. His body moved on autopilot, his feet stepping before his brain could catch up. He felt your hand slide around his wrist, pulling him into your apartment, like his legs weren’t moving fast enough for either of your liking. He looked down at you, and a giggle escaped your lips.
“Don’t get all shy on me now.”
His mouth was dry.
God, you would be the death of him.
“You nervous or something?”
Fuck, was it obvious?
“No. Just…letting you take the lead.”
You hummed in approval, turning back around, your hand still encircling his as you led him through the front door and to your couch. You turned around, facing him again, gazing up through your lashes, your wide eyes hypnotizing. Sukuna felt himself leaning in and down to your face before you pressed a finger to his chest. He grunted in protest, irritation evident. You only offered a small smile.
“Sit.”
He sat.
Your smile widened. “You listen so well,” you commented, taking small steps forward, still standing, now slightly positioned between his open legs.
“Don’t start.” He took his hands and dragged them up and down your calves, his fingers drumming the back of your knees. His touch was instinctual, your body like a magnet, an attraction his body could not fight any longer.
He had to touch you. He was scared he might combust if he didn’t do so any longer.
“You gonna sit too?”
“Eventually.” You leaned forward, bracing your body on the back of the couch behind Sukuna. He leaned back in tandem, his eyes dark, pupils blown, legs stretching open wider as you brought your knee up, its weight sinking into the couch cushion, dangerously close to his crotch. “I just wanna make some things clear with you.”
He nodded, his hands slowly moving up from your calves to the back of your thighs. You could feel the heat of his hands through the fabric of your jeans, and your chest rose and fell at the memory of when he had his hands last on you. You dragged your other knee up, now fully in a straddling position, and brought your hands down, your fingers playing with the curls at the back of his neck. You saw his Adam’s apple bob as he kept his eyes on you, flicking down to your lips and back up, tracing the planes of your face. His hands kept roaming, the pads of his fingers still curled into your thighs. You hovered above, not fully sitting, teasing, not giving either what you wanted, what you came for, until you laid out stipulations on the table.
You weren’t sure where this confidence was coming from. Maybe it was the liquor running through your veins, liquid courage to get you kneeling above Sukuna, with him, his body so pliant underneath you. Or maybe it was the realization that you held the cards; you always did. For so long, you felt subject to the whims of the wind, where it blew you was the direction you stumbled in, but here, in your apartment, on your couch, with Sukuna looking up at you like you hung his moon and stars, and holding you like you would vanish at any second, you left the power of his desire rush to your head.
“I know you haven’t done this before, but I don’t like to share.” You started. Your thumb rubbed gently up and down the column of his neck, and he licked his lips, forcing his eyes back on yours. “If we’re gonna do this, I need to be it for you.”
“You’re it for me.” He repeated immediately. His earnestness made your lips curl up. “It’s only you,” he said, his voice raspy and low. His hands tightened around your thighs, pulling you impossibly closer. He felt starved like a madman, so hungry, so delirious that he thought you could get him to say anything you wanted. Blood had been rushing south ever since you wrapped your arms around his, and it had only gotten worse when he stepped foot in your apartment, your warm scent like an aphrodisiac, an addiction he wanted to bury himself in. He’d never been reduced to such a state, just pure putty in your hands, and yet, he’s right where he wants to be.
“I only want you.” His hands travelled further up, now resting on your hips, his thumbs sliding just underneath the hem of your white tank, lighting your skin underneath on fire. You inhaled shakily as he brought his head forward and down in solemn devotion, pressing the smallest kiss to your navel, right where the smallest strip of skin was visible between your shirt and jeans. Heat pooled deep, burrowing itself in your core, and you felt your heartbeat quicken, your blood like magma, carrying arousal throughout your being. He looked up at you through his lashes, a desperate craving puddling in his eyes like red rivers, their depth calling to you with the most primal tune that strummed through your entire body, a siren’s cry tantalizing you both.
“Please.” His voice cracked under the weight of his desire. ”Let me show you.”
You both were on the edge. Sukuna was like a chained dog, your leash wrapped around his collar, eyes set on the prize, waiting for the magic words to release him from this prison of torment. Your body, so close to his, your vanilla and hazelnut scent dizzying him so much he couldn’t think straight, the heat from your body and the feel of your fingers on his neck nearly burning him from how good the sensation is. His hands flexed on your sides, and his neck craned up, veins popping from the side as he strained his neck to reach for you.
“Please.”
A cord in you splintered. Your eyes, half lidded, were laser-focused on his. Slowly, agonizingly, you began to sink, dropping your weight on his lap, bringing your mouth closer to his face. Your breath was hot as it fanned over his skin, your whisper sending a shiver down his spine as you brought your lips to his ear.
“Fine. Show me.”
His reaction was immediate. With permission finally granted, his control snapped, leaving behind something animalistic and raw and dripping with want. It washed over and overwhelmed you, both too much and not enough, hot and heavy and everything you two had been craving.
He pulled your body down the rest of the way, refusing to deny himself the closeness of you on him. You gasped as you felt all of him beneath you, the sinewy muscle of his thighs and his hard center, pressing and pulsing against your heat. He swallowed up your gasp in a kiss, devouring the small noises you made when you finally made contact. Your eyes fluttered shut, as if depraving one of your senses would help you control yourself, but you couldn’t help your movements – your hands pulling at the hair at the nape of his neck, lifting his head back and deepening the kiss, your small turns as you nipped at each other’s lips, noses and foreheads brushing, your hips shifting back and forth, trying to relieve the smallest bit of pressure built up from weeks of yearning. His hand came around the back of your neck, his fingers buried in your hair as if he couldn’t bear for you to be further away for a second. His other hand came down to the top of your thigh, guiding you back and forth on his lap. The slight vibrations and the friction of your clothing rubbing against each other sent your heads spinning. He groaned inadvertently when you shifted over his bulge, and his grip tightened in your hair and on your hip, signaling you to move faster.
You broke the kiss for air, and he chased you forward, eyes glassy and pleading as you pulled back, chest heaving. You stared deep into his eyes, the darkest shade of red you had ever seen them, so dark they seemed practically black. He breathed out, voice and expression fucked out, even when you had barely touched. “What’s wrong?”
“Take off your shirt.”
His dick twitched. Like he was cast under a spell, he grabbed the bottom of his shirt, tugging it off and throwing it on the end of the couch, already feigning to get your lips back on his. He kissed you, sucking on your bottom lip as he took your hands, guiding them where he needed them, dragging them down the expanse of his chest, the feeling on your hands on his skin like euphoria, better than anything he could have ever dreamed.
“Touch me,” he whispered against your lips, his words littered between breathless kisses. “Anywhere. Anywhere you want. I need to feel you.”
Your heart felt like it was beating out of your chest. Greedily, you ran your hands along his skin, feeling every inch of his sculpted, toned body, his heat warming your insides. Your hands gripped his shoulders as you steadied yourself, grinding down on his crotch. He threw his head back, groaning, both hands shooting up to rest on your hips.
“Fuck,” he gritted out, your name coming out like a prayer. “Keep moving.”
You couldn’t stop even if you wanted to. You shifted your hips back and forth, your pace quickening as Sukuna assisted, little whimpers falling from your mouth as you launched yourself forward, burying your face in his neck. You flushed, too overcome with the sensations your body was feeling. Your breath became labored as you tried to control the searing hot ripple bubbling in your stomach. Sukuna took the opportunity to pull you closer, pressing open-mouthed kisses to your neck, nipping your skin everywhere you were sensitive, thrusting up into you, hardly reigning in his lust.
You dragged your hand down his chest, running over the ridges of his abdomen, curiosity and ardor clouding your mind as your fingers brushed over his clothed dick. You short-circuited when you felt him beneath you, how big and thick and hard he was, just from the little you had done.
He took your hand in his and guided it, rubbing it over himself, voice strained like a rubber band pulled taut. “You see that? You feel that?”
You nodded, unable to speak.
“That’s what you do to me.”
“God, Kuna, please, I – ” you whined, mind too foggy to even know quite what you were asking for.
“That’s how you make me feel.” His mouth only moved more ardently, sucking and nipping, glossing over the marks he was leaving with his tongue, the hot, biting sensation soothed by the gentlest kiss. You moaned when his lips found the back of your ear, the underside right near your lobe, so sensitive that when he pressed his lips there, you felt like your body underwent a factory reset, shuddering in his lap.
“You drive me fucking crazy.”
The coil in your stomach reared back like a viper about to pounce. Another grind along your core hit exactly where you needed it to, and your neck craned back in pleasure. A high-pitched whine escaped from your throat, and your eyes squeezed shut. “God, Kuna, I’m – ”
You felt him grunt against your chest, his arm wrapping around your waist. You yelped when you felt him stand beneath you, your arms flinging back to his neck, and your legs immediately wrapping around his hips. He carried you, supporting your weight with one hand as he made his way through your apartment, pushing your bedroom door open, still peppering kisses along your neck and jaw. Your head swam from the sudden loss of stimulation, and when your back hit the cushiony plush of your comforter, your legs hanging off the edge of the bed, you leaned up, resting your weight on your forearms to stare at Sukuna, who towered above you.
You blinked slowly, trying to steady yourself. “What – what’re you – ”
Your words died in your throat as your vision cleared and you saw him sink to his knees.
His hands came up, caressing the backs of your calves as he spoke. “You need to know how fucking sorry I am for ever making you feel like that. I need you to know.”
“Sukuna, I do know.”
But he only shook his head. “No. I’ll never say it enough. But,” he stared at you with eyes that made your thighs clench closer together. He wet his lips. “Please. If you’ll let me…”
“Kuna…”
“I wanna taste.”
Jesus fucking Christ. You felt your heartbeat stop as your cunt began to pulse. It was as if you could feel every cell rushing through every vein, every sense lit on fire by his words, melodic to your ears.
“Please. Let me taste you.”
You didn’t trust yourself to speak, so you only nodded. You began to move your fingers to unbutton your jeans, but Sukuna pushed your hands aside, ready to do it himself.
Painfully, agonizingly slowly, he undid the top button to your jeans, his fingers pulling down at the zipper and brushing over your mound of skin, already sensitive from earlier. You were embarrassed by the slight gasp you let out, but Sukuna couldn’t be bothered by how reactive you were to his touch; if anything, it fueled him.
He unzipped and moved toward your hips, pulling the fabric down over your thighs and knees, finally pulling off each leg and leaving you exposed in your underwear, tank top, and bra. His eyes honed in on your pussy, the lacy black material leaving so little to the imagination, you could almost hear the lewd thoughts spilling from his mind.
But nothing was ever easy with Sukuna. Like he was taunting you, he started at your lower leg, kissing up around your calf, to the back of your knees, up, up, to the plush of your thighs, sharing equal attention to both legs. You couldn’t help but begin to be antsy as he dragged his lips up the lower half of your body, kissing you everywhere but where you needed him.
He pulled at the skin of your inner thigh, biting lightly and still eliciting another gasp from you. You felt him grin against your leg. “So sensitive. Is that all for me?”
Him and his smart mouth. Just moments ago, he was on his knees, pleading to taste you, and now you could feel his canines against your skin, his smile teasing how visceral your body was to his actions. You wish you had the wherewithal to fire something back, but your mind and your heart and every other part of your body would begin to scream if he didn’t touch you the way you needed to be touched. What came out was on the verge of begging. “Kuna, please, I need – fuck! ”
Your plea was cut off by a long, slow, arduous lick up the lips of your pussy, through the fabric of your panties, so vile and crude it felt sacrilegious. Your back arched as his tongue made another stripe up your cunt, your fingers burying into your sheets, both the comforter and your face twisted in pleasure. “Oh, fuck,” you whispered, trying to breathe through the stimulation of his mouth and your panties working in tandem to wind you up.
You felt your legs begin to lock together, closing in around Sukuna’s head, and he brought his hands up to the outer sides of your legs, giving him leverage to push his face deeper into your cunt. His tongue lapped against your cotton gusset, already soaked from your arousal, and now dripping from his wetness. He pressed open-mouthed kisses against your core, pecking all around your clit to the point where you felt like you were vibrating from your aching cunt, all but pleading to be touched.
“Sukuna, please.”
“I know, princess, I know. Just wanna make you feel good.”
You were past the point of feeling good. You sighed as you fell back into your comforter, too wrapped up in your pleasure to hold yourself up any longer, instead trying to focus on keeping yourself together as his mouth continued working.
This wasn’t your first time being intimate with someone, but Sukuna was unraveling you in a way that made you blush like a virgin. With others, sex felt more like a means to an end. A transaction acts unspoken until necessary, a “not there”, a “wait, that doesn’t feel good”, an awkward laugh as you adjust positions - something to relieve stress and get both parties off quickly, if you were so lucky.
Sukuna, who was just rough and tumble and aggressive and sullen all over, instead, cupped his hands around your waist like you were glass, his tongue lapping at your essence like a dog in heat. He reached up, still kissing your cunt, wrapping his fingers around the elastic band and tortuously pulling down, your slick pulling glossy strings down with it. You whimpered as the cool air hit your pussy, leaving you so exposed in front of him. Your body was flushed all over, but you still couldn’t help but feel embarrassed with your level of exposure, with Sukuna’s eyes devouring every last inch of you. You writhed in his grip, but his fingers held you still.
“Nah, don’t run, let me have a look.”
You shut your eyes as you felt his thumb rub over your lips, ghosting over your clit.
“So pretty,” he muttered, his hot breath hitting your wetness.
And all of you was so pretty. A sight to be seen, one he revealed in you being kind enough to show him. He watched as your back arched off the bed, your chest heaving up and down, skin glistening as his fingers and mouth worked you up, you shuddering as his mouth ghosts over your clit, your subtle thrusts forward as you tried aimlessly to grind yourself on his mouth, begging for a hint more of friction. It was cute, honestly, seeing you pretend not to be so needy.
Your whimpers felt like they had a direct line from your throat to his blood, fueling him, egging him on. He finally caved, wrapping his lips around your bud, and the moan that left your mouth was heaven to his ears. Your fingers ran through his hair, nails dragging across his scalp as you pulled his face closer to you, as if asking him to ruin you wholly. He smiled as you began to fall apart beneath him, your breaths turning into pants, your pussy squeezing around nothing, coaxing to be filled. He felt himself rutting into the bed frame in front of him, chasing the high he was currently giving you.
He sucked on your clit, and it pulled out another moan from you as you trembled beneath him. He kissed it gently, looking up at you with the most reverent, pussy-drunk eyes that made your stomach do flips. “You taste so fuckin’ good, baby.”
Baby? Your hand flew up to your mouth to muffle the wanton sounds you couldn’t control spilling from your mouth. Your eyes were screwed shut as you felt yourself tumbling, your breath fighting to escape your lungs, the coil in your stomach so fucking tight you thought you would die if it weren’t released. You felt Sukuna’s teeth nip at your bundle of nerves, and you choked back a scream, your hand pressing more firmly into your mouth as you reared your head back even deeper into your mattress.
Sukuna’s tongue clicked in the back of his throat. The gasps and moans coming from you, whether involuntarily or not, were quickly becoming some of his favorite sounds, and he wouldn’t stand for you taking that away from him.
You felt Sukuna’s hand reach up, wrapping around your wrist and pulling it down from your mouth. “Mhm, lemme hear you, princess.” His fingers intertwined with yours as he pushed his tongue deeper into you, still lapping over your clit as you sighed, the pleasure washing over you like waves.
“God, Sukuna, it’s – I’m gonna – ” You were so beside yourself you couldn’t even form a coherent thought, let alone a sentence. You felt your mind start to go white, your breath coming out fast and sharp as the pressure became insurmountable.
“It’s ok, it’s ok,” he soothed, still gripping your hand with one and rubbing the side of your thigh with the other. His pace never ceased, his tongue rolling small circles over your bud as you felt your climax building higher and higher. He tugged on your arm, prompting you to raise your head and locking eyes with him, his pupils so blown it felt like you were staring into midnight.
“Come for me, baby.”
A searing, white-hot flash, then stars, spinning as you felt your spine arch, your fingers squeezing his hand as you came, his mouth still kissing you through your orgasm. The release of pressure felt so good that you could feel the tears pricking at your eyes, your gasps deep like you were trying to catch your breath. You twitched as Sukuna continued to lap you up, his chin and lips wet from your release, and you couldn’t decide if you wanted to push him away or if you needed him closer. “Kuna,” you moaned, too overstimulated to manage anything else out.
He kept circling, kept licking, kept kissing like a man addicted. Like it was his full-time job, like if he stopped, you would escape his grasp, fall just out of reach again, like things would go back to the way they were.
“Just one more, princess. You taste so damn good. Can you give me one more?”
You shook your head, crying out. “It’s too much, please – ”
You were cut off by a silent cry, a sob that wracked your body as he rolled over your puffy clit again, your body overheating with how much you were feeling at once. You heard Sukuna grunt as your fingers curled in his hair, as if you were trying to ground yourself in his pink tufts. You whimpered out his name again, your second climax rapidly approaching.
“One more, baby, I need it. Please, just give me one more.”
It’s like his voice was a trigger with how responsive your body was to it. You gasped as your second orgasm wrecked your body, your thighs shaking as they wrapped around Sukuna’s head. His entire being was light from the pressure and essence of you all over his tongue; he felt deluded. Your eyes fluttered shut as your head lolled to the side, your chest rising and falling rapidly as you tried to steady yourself, your entire body still buzzing from the two orgasms he pulled from you with just his mouth.
He pressed one last kiss to your pussy, and crawled up from his kneeling position, his body hovering over you. He wiped his mouth with his hand, licking up the last bit of you as you looked down at your figure, his smile bigger than you had seen it. The moonlight streaming from your window cast an angelic glow over your body, your skin practically illuminated as he drank your figure in.
“So gorgeous,” he whispered, leaning back down to press kisses against your neck. “You’re so beautiful. You did so well, princess.”
You moaned lightly, rolling your head back to give him more access. He kept kissing along your jaw as he spoke. “Are you ok? Was that too much?”
You opened your eyes, your half-lidded irises trailing over your project partner’s face. The same face that stared at you so sullenly, whose eyes flashed an angry red when you dared to talk back to him in the library, whose jaw clenched when you’d even entertained the idea of being interested in someone else, from whose mouth dripped nicknames and praises and words that made your stomach churn and pussy flutter, was now leaning above you, shirtless in his tanned and inked glory, asking if you were ok, attraction coming off his skin in heat waves.
You brought your hand up to his chest, your fingers daintily coming around the back of his neck, gently pulling him closer to you for a kiss. His mouth met yours, his hand resting between the juncture of your jaw and neck, cradling you as if you were something fragile. You pulled at his bottom lip, biting gently as you let go, looking at him with eyes coated in a mist of lust.
“Ryo, I need you.”
His world stopped. He became so painfully aware of his dick, aching, hard as a rock pressing against the seam of his pants, the front already damp from pre-cum that he felt his whole body vibrate. The veins in his arms popped as his grip tightened in the sheets below you. He thought he misheard you, but the look on your face and the need in your tone couldn’t be mistaken.
“You – ”
“I need you,” you repeated, leaning up. Your hands moved to the bottom hem of your white tank, pulling it over your head and leaving you in nothing but the lacy black bra that cupped your curves just right. You saw Sukuna’s throat move in a swallow, his eyes flicking between your chest and face, like he didn’t know what to look at.
He leaned forward, stalking toward you like a tiger, and you leaned back in tandem until the back of your head hit the pillow, and you were inches apart. You took a sharp inhale when you felt his heaviness pressing against your leg. His voice was strained as you spoke.
“Are you sure?”
You bit your lip, nodding. Your bra strap slipped off your shoulder, and his eyes tracked it like he was hunting. He rocked back, kneeling on your bed, his fingers nimbly unbuckling his belt and unzipping his jeans as a shadow crossed his face, his features impossibly sharper and eyes dark like dying stars, glinting in the night.
“Show me.”
Your pussy clenched. Your mouth went slightly dry. “What?”
“Show me how much you need me.”
This cocky motherfucker. Your breath was shaky. The tension had been built so high up that you couldn’t separate your gazes of fear of shifting the veil, removing yourselves from this singular moment where it was just you and him, eyes boring into each other, fires burning so passionately and breaths so aligned it was as if there was only one in the room to share.
Slowly, you brought a hand down toward your center, aching and leaking and begging to be filled, and deliberately took two of your fingers, spreading your folds, and began to rub, warming yourself up but keeping your eyes locked on him.
Sukuna’s inhale was sharp as he slid his belt out of his pants, swiftly taking them off and began palming himself over his boxes, his tip beading pre-cum and growing harder by the second as he watched you touch yourself. He ran a thumb over his tip, and you saw his abdomen contract, his Adonis belt sharp and mouthwatering and oh so tempting as you traced a vein down, disappearing into the black band barely obscuring the last part of Sukuna’s toned body. His dick was upright, flushed against his abs, and you felt your walls flutter as you looked back up at him, his jaw clenched so tight as he tried to control himself.
You touching yourself wasn’t enough, not after the ecstasy he’d given you only moments prior. You needed more, needed him, in you, filling you up, forcing you to chase that high of pleasure again. You settled for dipping a finger in, your head softly hitting the back of the pillow as your mouth opened, forming a small ‘o’ as your gasps came out in little pants.
Somewhere in your haze, Sukuna had discarded his boxers, leaving himself fully exposed to you, his dick flushed and red and erect in all its glory. He stroked it up and down, matching the pace of your fingers pumping in and out of your cunt, as if transfixed. The wet, slick sounds in the room made you want to turn away in shame, but Sukuna knew you, knew your body and reactions, too well.
He shook his head, his voice deep. “Eyes on me, princess.”
You wanted to cry in protest, but you kept going, barely holding your head up to stay focused on him, on his irritatingly handsome face, his eyes, which gave away how much he was affected by you, even if he didn’t want to admit it. You felt your free hand go up to hold yourself, clutching at your breast as your finger and thumb rolled over your nipple through the lace, your body begging for another form of stimulation as you remained locked under Sukuna’s gaze.
You added another finger, trying to simulate an iota of sensation that Sukuna would, but it still wasn’t satisfying. You pressed up, curling, trying to hit your sweet spot, but you couldn’t get there, no matter how hard you tried. “Ryo,” you whined, dragging out his name in a way that made his dick twitch and body shudder. “Please, stop teasing. I need you.”
Fuck. Your words wrapped around him, seeping into his pores and entering his nervous system like a drug. He was an addict, addicted to you, to your voice, to the scrunch of your nose, to the way you looked sprawled on your bed. Every inch of you, he craved, wanted to know intimately like a painter knows his subject. He watched intently as your fingers dipped inside you, and his heart hammered at the idea of sheathing himself in you, the thought making his head rush.
He crawled forward, coming closer to you, capturing your breath in another kiss. He pulled back and took your hand you had touched yourself with, still glistening and wet from your slick, and brought it to his mouth, sucking your taste off each of your fingers, all the while staring at you with a gaze that had you at a loss for words.
He let go of your fingers with a pop, then lowered himself to hover over you, reaching down to line himself up with your entrance. He rubbed his tip between your folds, and you moaned at the simple act. Sukuna hissed, trying not to bust when he hadn’t even gotten the chance to sink into you yet. He grunted, whispering your name. “Tell me if it hurts.”
You nodded, too turned on to do anything but. He breathed out, then, slowly, pushed in.
“Fuck!” He grunted. He’d barely made it through your first ring of muscle, and your walls were so tight, pussy gripping onto him like a vice, he was worried if he went any deeper, he’d finish prematurely. Your hands immediately scrambled to his bare back, your nails digging into the muscle as you gasped at the feeling of him entering you. You knew he was big, but Jesus Christ, you were worried he would split you in two.
You hung off his back as he paused, searching your face for inklings of pain or signs of discomfort, you both panting as your chests rubbed together. His stopping felt like torture. “Keep going,” you breathed out.
“You’re gonna kill me, princess,” he muttered, but obliged, pushing more of himself in until he bottomed out with a groan, your walls tight and sticky and warm and every bit as narcotic as he thought they would be. He felt he could die here, trapped between your walls, with your wide, watery eyes staring up at him, lips swollen and glossy with spit from your kisses, and so beautiful underneath him he felt like an idiot for taking so long to realize.
“You okay?”
You nodded, fingernails digging deeper into his back, and he groaned at the pain that brought him such pleasure. “Please, Ryo, move.”
He didn’t need to be told twice; his hips moved in sharp, snapping forward motions that made your eyes flutter closed and move in sync with him. Each thrust sent you both deeper and deeper into oblivion, your head so foggy all you could do was moan as his tip kissed your cervix, so deep inside you, you almost wanted to scream.
His hand and mouth found your chest, his lips kissing and sucking and biting at the chest above your chest as his fingers worked blindly to unclip your bra. The lacy black material fell to the wayside as he moved down, rolling one nipple between his fingers and the other over his tongue. The combination of his size filling you up so perfectly, and his fingers and mouth on you, left you babbling, chants falling out of your mouth as you felt your body shake. Your nails scratched down his back, trying to release the pent-up tension in your body in any way you can.
You felt your voice leave your body when his hand came down to push your leg up, pistoning deeper at an angle that left you seeing stars. He grunted, pressing his leg up as he hit a gummy patch in your walls, and you screamed his name, too fucked to care about your volume. “There she is.”
“Fuck, Ryo,” you sobbed, feeling past the point of no return. Each drag of his dick along your walls, feeling each vein rub against your skin, the slick wet sounds, and the smell of sex permeating the air, all sent you spiraling, tumbling down uncontrollably into your climax, this time building like a boulder in your stomach.
Sukuna felt it coming as you squeezed around him. He maintained his pace, bringing his mouth up closer to your ear, kissing along your neck and jaw as he spoke.
“Whose dick is this?”
It was like the gasp was ripped from your chest. You couldn’t bring yourself to answer; it might’ve sent you over the edge. You warbled out a mumble, but it wasn’t enough, not for Sukuna.
“Nah, I’ve been dealing with that smart mouth all semester. Don’t get all quiet on me now.” You felt him drag his thumb down, rubbing small circles over your bundle of nerves. You would kill him if you didn’t want to come so badly, tears started to fall, sliding down your cheeks. He only smiled, kissing the trails away, the masochist.
“C’mon, baby. Whose dick is this?”
A sob wracked your body. “It’s mine,” you cried out.
“That’s right, it’s all yours. I'm all yours, ‘nd only yours.” He punctuated each word with a thrust you could feel in your throat, your clit screaming from his thumb, and body wound so tight, you could feel yourself beginning to fall. He felt his climax coming too, his dick so hard it felt like it would fall off, and he leaned down, swallowing your cries in a kiss before whispering to you again.
“Now come for me, princess. Please.”
This last orgasm shook you to your core, ransacking your body and leaving nothing left. You gushed out, a high-pitched moan shuddering from your body as he kept thrusting, his orgasm chasing swiftly after yours. The feeling of your constricting around him, your juices flowing from your last climax, you cum mixing and acting like a lubricant, all made him feel crazy. His thrusts got sloppy and erratic as he neared. “Fuck, baby, you did so good, you feel so fucking good.”
“Ryo,” you whispered sleepily, every ounce of energy drained from your body as you came down from your high.
He looked up at you.
“Come inside me, baby.”
Shit. You looked so perfect, so fucked out, so otherworldly as you stared back up at him. You had done so well, had taken him so well, he almost faltered. “You –”
“Please, Ryo.”
Fuck, you’d be the death of him. He leaned forward, feeling so good he damn near whimpered into your neck, his face twisted as his hips stuttered as he came, filling you with hot ropes, the white substance leaking from your pussy as you both groaned from the feeling of him finishing inside you.
With a shaky breath, he lowered himself carefully, still lodged between your thighs, his weight resting on you but not crushing you, enveloping you safely. He wiped another tear from your cheek as you caught your breath, your eyes barely open. He kissed each eyelid lightly to not disturb you. “You ok?”
You nodded, too overwhelmed to bother forming a sentence. You two stayed like that, bodies connected, warmth transferred as you twitched around him, still so, so sensitive. Without thinking, your hands went up to his chest, tracing the sharp lines of ink that ran across his torso, up towards his neck, down towards his hip bones. You felt his shift inside you, still half hard from what had just transpired. You shook your head as he smiled without remorse, tugging you closer. “You’re impossible.”
He only kissed you in response, this one gentle, and slow, careful as he gently stroked your side. He stole your breath, pulling back and leaving you dizzier than previously.
“You always this touchy after sex?” You asked, winded and delirious from the past hours’ events.
He shook his head. “Just with you. Only with you.”
You sighed as he finally pulled out, his warmth leaving you feeling empty and already craving his touch again. He stood, heading to your bathroom and grabbed a wet, warm cloth, coming back and wiping you down carefully. Only then did he climb back into your bed, pulling the covers over your bodies, as if the heat you two generated wasn’t enough to keep you both warm, and pulled you into his chest, your limbs tangled, so intertwined it was hard to tell where he ended, and you began.
The sleep that overtook you both was the most peaceful you’ve had in months.
You only arose the next morning when the sunlight streamed through your window, its rays casting a glow on your face as you stirred, your back absent of Sukuna’s large, muscled warmth. You took in a breath, rubbing your face with your hands, and were distressed at the makeup from last night smudged around your eyes.
You turned, covering your body with the loose-fitted sheet, and furrowed your brow at the smell of something being fried in your kitchen. You rolled out of bed, slipping on some clean underwear and a discarded hoodie littered on the floor, and padded out of your room, your stomach grumbling at the idea of breakfast.
You stopped short at the sight of Sukuna, in your kitchen, shirtless, hips resting against the stovetop as he fried eggs, two plates with buttered toast waiting to be served. Miso sat in the corner of the room, slightly miffed at the not-so-strange stranger in her kitchen but pleased she had been acknowledged and fed by someone. She meowed at your disheveled entrance like a disappointed roommate, keenly aware of what transpired last night.
Sukuna looked up, attuned to your arrival. His eyes shot down to your bare thighs, trying to conceal his smirk at the love bits you clearly hadn’t noticed yet. “Hey.”
“Hey.” You had the nerve to sound sheepish. You cleared your throat. “Uh, good morning.”
“More like afternoon. It’s past 12.”
“Oh.” You fiddled with the ends of your sleeve. “Right. Guess I was really tired.”
“Princesses need their beauty sleep, right?” He chided, flipping the eggs in the pan, their yolks a royal gold color.
You hummed, propping yourself up on the counter behind Sukuna as he turned his attention back to the stove. Your eyes widened, and you flushed at the red, raised marks like claw stripes on his back, and the memories of last night came rushing back in a wave of heat.
“Hey,” he murmured. Your head snapped up, and he stood in front of you, pressing a finger against your forehead. “Don’t get trapped in there. Tell me what you’re thinking.”
“Nothing.”
His eyebrows flicked up as he caged you in, his thick arms resting on the countertop on either side of you, bringing his face in close. “What’s wrong?”
It was evident he wasn’t gonna let this go. You bit your lip before asking. “What…is this? What are we now?”
His eyes widened in incredulity, but all he could do was laugh when he saw the earnestness in your face, the vulnerability in your question. He let out a disbelieving laugh. “You serious? Did you actually just ask me that?”
You shrugged. He stared harder.
“I meant everything I said to you. In the library, at the party, certainly last night.”
You flushed before prattling on. “I just thought – ”
He tsked. “Stop doing that. You think too much. Complicates shit.”
He pressed a chaste kiss to your forehead before turning back around, scooping the eggs out of the pan and serving them on top of the toast, bringing a plate and fork over to you. He took a bite of toast, chewing as he continued.
“Like I said last night, I’m all yours. And by the way you were screaming my name, I’d assume you feel the same.”
You scowled, your leg going out to kick him as he dodged, laughing at your antics. “You didn’t even ask me, dickhead.”
“Ask you what?”
“To be your girlfriend,” you mumbled shyly, kicking your feet as if you both hadn’t bared your souls to each other just last night.
Your chastity made him bite his inner cheek. You were too damn cute for your own good. “You want me too?”
You shrugged again, reaching for your toast. “Princess treatment, right?”
He smiled despite your feigned ambivalence. “Alright.” He grabbed your hand, pressing a kiss to your knuckles, staring at you deeply with content and admiration and a mix of something else you weren’t quite ready to name, reflecting at you in his eyes.
He said your name like it was his favorite thing to hear. You hummed, as if telling him to proceed.
“Can I be your boyfriend?”
You smiled, flicking your brow up. He sighed, shaking his head.
“Please?”
The grin that stretched across your face made his heart skip a beat. You wrapped your hands around his neck, bringing his face closer to yours.
“Hmm, maybe I was right. You are a fast learner.”
His hands found your hips, rubbing small circles there as he grinned back, the type of grin he could only let you see.
“Yeah, well, I had a pretty good study partner.”
