Chapter Text
“As if I’d let you anywhere near her.”, Yuuji snarled, directing his venomous glare at the cocky bargainer in front of him. The glowing red of Sukuna’s innate domain created shadows on his angular face and his blood red eyes glowed like coals in a fire. The lines of ink tatted on his skin were as bold as ever.
“Considering your situation, brat, I’d say you are in no position to decline.”, Sukuna stated. Although his velvety voice was mostly calm and collected, the faintest smirk was audible. He knew he had Yuuji in the palm of his hand and this filled him with sadistic joy that he was struggling to contain.
Yuuji gnashed his teeth, brows furrowed, eyes shooting daggers. This arrogant bastard, he thought to himself. Of course, he supposed being called the King of Curses for centuries might start to go to a persons head. He was backed into a corner. He would sooner do many things than allow Sukuna in the grace of your presence.
You were a best friend, the person he allowed himself to be intimate with, without the stress of labels, but deep down he had a possessive streak that was rearing its ugly head. You were his girl and Sukuna knew that. This only tempted him more. Yuuji knew the curse he contained had developed an interest in you. His perverse thoughts would constantly swarm around his mind, almost like white noise in the background, as Itadori would spend time with you, forced to share a body with a brazen curse. One who continued to think obscene thoughts of you.
Over the time you had known Itadori, Sukuna couldn’t help but grow enamored with you. Such a perfect, sweet creature. Never in his time in any age had he felt such a burning, demanding need to conquer and claim. And of course the brat he was stuck with was crushing on you. He took this time as an opportunity to voice his demand. Sukuna had the upper hand and Itadori could only refuse if he wanted to remain deceased. The king internally smiled so wide his cheeks ached and his canines scraped along his bottom lip. It was perfect. He would finally get what he had been craving.
Itadori Yuuji swallowed shakily, feeling the pangs of defeat in his chest. Sukuna forced his hand. “When you’re around her, you are not to harm a hair on her head. Or I’ll have yours on a stake.”, Itadori stated with a hard edge in his voice. Obviously, it would be in a metaphorical sense. After all, he was the physical form carrying the burden who was Sukuna. “Of course. Just a taste.”, he promised the brat.
The king before Yuuji felt a smirk blanket his features. Finally. He would have you.
**************
You sat in the garden on school grounds, deeply breathing as you took in the sounds of summer. The soft gushing of water in the fountains, koi fish occasionally splashing in their ponds as they caught insects out of the air. Cicadas were buzzing. The air was thick with humidity. Nobara was off training and you were due to spend time together later this afternoon.
You were one of very few people who were aware that Yuuji was alive, and you were sworn to secrecy. Your chest swelled as you thought of him. The silly boy you couldn’t get out of your head, even if you wanted to. That idiot. With a huff, you stood up and brushed yourself off before walking to your dorm. You liked to get your training done and over with in the early morning before it got uncomfortably hot and steamy outside. Now you had the bulk of the day to yourself to focus on your studies, read, or explore your relatively new surroundings. You had only been a student at Jujutsu Tech for a few months.
You halted in front of your room and as you reached for the door knob, you felt a rush of air as you were quickly tugged through the now open door frame, and pressed against the door as it closed with a resounding ‘click’. Your lips parted in surprise and as your eyes adjusted to the dim lighting, you were able to make out Yuuji’s facial features.
You huffed in exasperation before lightly thwacking his shoulder. “You bone head, you aren’t supposed to be hanging out around here. What if someone sees you?”, you hissed. Although you could never stay mad at him.
Never mind the fact that it was forbidden for boys to linger around the girls dorms, he was thought to be dead.
“Awww, sweetheart, I thought you’d be happy to see me.”, he murmured with a playful pout, baby brown eyes staring down at you.
“If someone caught you in this hallway, we’d both be dead.”, you said in wonder with a hesitant giggle. The rules being broken filled you with adrenaline. It was kind of exciting.
“Gojo-sensei has been putting me through the most boring training”, he drawled, leaning down closer to your ear. “And I couldn’t stop thinking about you.”, he whispered. A shiver jolted through you as his breath tickled the shell of your ear. You thickly swallowed, heart hammering against your ribs. You felt your knees grow weak and your cheeks started to flush at the realization of what this man did to you when he was like this.
You both casually fooled around in secrecy, and you were surprisingly good at it. Not even nosy Nobara, your pushy, bossy, yet endearing friend had found out and that said something.
You offered him a breathless smile, eyes twinkling, as your arms wound around his neck. His face broke out into a full grin as he reached to turn the lock on the door he had you backed up against. He moved his hands to the globes of your ass under your skirt.
Today, students had been allowed to wear more casual summer attire and you silently thanked your past self for picking a skirt.
You kicked off your shoes before jumping up into his arms. His thick muscles tensed around you as your legs wrapped around his torso, easily holding you against him. Your eyes fluttered shut just as your lips pressed against his warm, soft ones, slowly moving in an enhancing rhythm that made your heart beat that much quicker.
You felt him walk the both of you to your bed before tossing you like a rag doll upon your plush mattress, the cool silky comforter soothing your flushed skin. He crawled tantalizingly slowly over your body and you felt his face hovering above yours. As your eyes fluttered open, you nearly yelped.
Thick, bold, jet black markings danced across his face and arms, perhaps more elsewhere, but those eyes gazing down at you stopped you in your tracks. Red like wine and filled with a hunger that you had never seen before. The corners of his mouth slowly curled into a smirk and canines peeked through his plush lips.
Your eyes widened a fraction and Sukuna loved it. You resembled a fearful fawn caught in a pair of headlights. A soft, velvety chuckle left his chest and the vibrations tickled you where your skin met his.
Of course you knew that Yuuji carried Sukuna within him, but never, not once, had he lost his footing like this. He always promised to you he maintained control and would never let “that fucking pervert” anywhere near you. Your legs trembled with the realization that this wasn’t Itadori looming over you anymore.
Your lips parted as you audibly gasped. Sukuna trailed the pad of his thumb along your jaw line before ever so gently tracing your bottom lip, eyes carefully observing your face. “Sweet thing,” he breathed, warmth fanning across your face, causing your lashes to flutter. Although Yuuji had assured you that the curse he carried was diabolical and craved destruction and death, he couldn’t have been acting any more different towards you.
In fact, your chest nearly ached over his gentle words and touches and you scolded yourself for it. You should have been making a move to shove him off of you, demand that he bring Yuuji back, but you realized with a shock that you didn’t want to. Not just yet.
You blinked up at him and his almost dazed face was graced with a soft, awe-filled smile. It was with a sudden realization that you noticed the throbbing in between your legs. Goddammit all. What was wrong with you?
Your thighs slowly inched closed, feeling as though that would shield your aching heat from your surroundings and the beautiful, awful being pressing you into your fluffy bed spread. This didn’t go unnoticed by him and he softly tsk tsk-ed under his breath.
“Princess, is that any way to get what you want?”, he murmured, gazing into your eyes. Your lips parted once more at his pet name and with a shocking amount of effort, you found your voice. “How could you know what I want?,” you asked airily, suppressing the shaking that threatened to make your voice tremble.
Your sweet yet sassy tone surprised him in the best possible way and it was all Sukuna could to to suppress a groan as he felt your comment go straight to his cock. He chuckled once more. “Oh, baby, you are not nearly as subtle as you believe yourself to be.”, he said with great amusement. He was going to have so much fun with you. You were absolutely perfect for him.
You furrowed your brows at him, attempting to glare, and he nearly cooed. So cute, even more so when you were mad. He abruptly forced his thighs in between your own and spread them with astounding ease. With just as much grace, one of his hands trailed up your figure before yanking your wrists together and over your head, forcing your back to arch just a bit.
He gazed with hunger. If he could have this image made into a painting, he would. Your hair tousled across your satin pillow, eyes full of unwavering curiosity and longing, flushed cheeks, moist, pouty lips parted as you tried to steady your breath, your perfect tits ever so slightly forced up into the air. “My, my, little lamb. Aren’t you the prettiest thing I’ve ever seen.”, he mused softly, almost entirely to himself, as though he wasn’t aware he actually said it aloud.
You couldn’t stop the small moan that escaped from your chest and tumbled past your lips even if you wanted to. Half embarrassed, half lustful and filled with such an aching need you could combust. His words went straight to your clit and you could feel your heartbeat in between your thighs.
It was his turn for his eyes to widen, almost in disbelief that you were so willing, wanting this just as much as he did. His free hand danced up under your skirt, fingers leaving a tingling trail in their wake. You felt his fingers hook around the band of your panties, and yet his eyes never once left yours. Without thought, you drew your bottom lip in between your teeth, in anticipation or an attempt to stop yourself from making anymore unwarranted noises, you weren’t sure. His eyes watched the movement and the soft material of your underwear glided down your legs before they were completely off.
Placing his thighs back between yours to keep them spread, Sukuna slowly lifted the article of clothing up to his face, fisting it and inhaling deeply. A soft growl left his chest. He could smell your fabric softener, your skin, your slick, it was almost too much to bear. They were unceremoniously tossed aside, his dark, hungry eyes intent on your face that was still gaping up at him.
Pervert was correct. His thumb firmly pressed into your chin as the knuckle of his index finger guided your head up, until you were directly facing him. “Open”, came the swift demand, and without pause, your lips parted, opening your mouth. His fingers left your chin, only to delve into the wet warmth of your mouth. Your eyes fluttered shut and your tongue brushed along both digits, ensuring they were completely wet. His fingers almost felt like they were massaging your tongue and a soft sigh left your nose.
His eyes widened and his lips parted, gazing down at your content face, suckling his fingers, lashes brushing along the tops of your cheekbones. Perfectly obedient, seemingly happy to please. Sukuna couldn’t help but think Yuuji was a damn fool for not enjoying these facets of you. What a waste. But he would ensure he put them to proper use.
He gently pulled his sopping wet fingers out of your mouth with a ‘pop’ and your eyes fluttered open, gazing up at him. “Offer, baby.”, he murmured, and you dumbly spread your legs farther, knees coming up to rest on either side of your waist. Your cheeks flushed even more at your lack of hesitation. His hand left your wrists as he slid down in between your legs, his warmth seeping into the plush of your thighs as his arms wrapped around them, fingers pressing into the flesh but not harshly so. Your skirt pooled and collected at your hips, exposing your most sensitive parts.
Your breathing hitched as you felt his hot breath fan across your soaked, throbbing pussy. He finally couldn’t suppress it anymore and let out a groan, expression nearly looking pained as he came face to face with your cute little cunt. The way it glistened with your slick, catching the dim light coming in through your curtains, nearly drove him to madness in that exact moment. You slammed your eyes closed and your back involuntarily arched at the sensation, a whimper escaping from you. “Please”, you whispered.
Yuuji never toyed with you this much, let alone reduced you to saying please. But then again, this person could not have been any more different than him if he tried. “How badly do you want it, princess?”, Sukuna asked, voice firm and dominant, yet velvety smooth.
This bastard was going to make you beg. And with that thought, you abandoned the last of your sanity and self preservation. “I’ll do anything, King. Please... please make me come.”, you pleaded, hushed voice shaking while your cheeks and ears heated.
He smirked as your words stroked his ego. Blushing while begging for him to give you release, he thought. The irony nearly made him laugh. You were acting as if he’d already fucked you stupid and he had hardly even begun. This realization made him almost salivate. What a good girl. “Say my name.”, he demanded coyly. You softly exhaled, almost in exasperation while squirming under his watch. “Please, Sukuna”, you whispered. And that was enough for him.
He smirked and began leaving love bites all along your inner thighs, small purple marks appearing where only you could see them. Once in a while, you could feel a small sting as he applied pressure with his canines and your clit began to throb harder with each nip.
Sukuna felt something deep in his chest and he decided then and there that he was going to leave a rather memorable mark. This one would be special, much different from the bruises that were already forming. He used the smallest possible amount of cursed energy and as he pressed his lips to your skin once more, the mark was painlessly inked onto your soft flesh. It was a dainty “S”, the calligraphy similar yet different from that which covered his body. His lips twitched into the smallest smirk.
He knew he promised Yuuji he only wanted a taste, but there was just no way, after getting said taste, that he’d be able to leave you alone. This would ensure that you remembered who had been there last. And who’d be there later.
He wanted to thoroughly rile you up and leave his marks on you before moving to your soaked pussy. But as he gazed up at you through his lashes, watching your flushed face react with each movement of his mouth on your inner thighs, he found himself growing increasingly impatient.
He had never been this eager to please another being in his life.
With this last thought, he slowly trailed his lips to your clit, leaving your inner thighs wet with his saliva, and you nearly cried out from the sudden impact before remembering you needed to keep quiet. “Baby, you’re drenched.”, he purred in awe. At this comment, you softly moaned, and gently (embarrassingly) bucked your hips, futilely searching for some form of friction.
He clicked his tongue in displeasure, moving one of his hands to your hips to hold them down. “Be a good girl for me and stay perfectly still.”, he whispered.
You whimpered and weakly nodded. “Can I at least touch your hair?”, you asked, voice so strained and quiet he could scarcely hear you. “Of course, angel.”, he said silkily. You wetted your lips and rolled your bottom one between your teeth before moving a hand to his blush-pink, silky locks, entwining your fingers through them. Your eyes fluttered shut, comforted by the touch.
You felt him smile into your slit before masterfully suckling on your clit and spreading his tongue, running it up and down your folds. You whimpered, seeing stars as you fisted your comforter. And his hair.
He developed a pattern, moving from your clit to your dripping wet slit, back and forth in a tantalizing manner. You were repeatedly driven to the brink of a shattering orgasm before being gently lulled back into waves of pleasure so you wouldn’t come too quickly. Sukuna wanted to tongue fuck you so properly, you could barely speak or move afterwards. He grew rock hard just listening to the sounds you were making and he couldn’t help but wonder... had it ever felt like this before?
He decided it hadn’t. Not once had he been driven so buck-fucking-wild while going down on someone. With each soft whimper and cry of yours, he had half a mind to flip you over and pound into you until neither one of you could tell where he started and you began. To claim you. Make you his little cum slut. His slave princess who would think of him and only him.
Your slick was practically dripping down his chin. He opened his eyes just in time to see you lose yourself.
The warm tingling tension in your belly finally snapped and you opened your mouth in a silent scream, brows furrowed, moisture pricking your eyes. The overwhelming pleasure washed over you and it took every last ounce of restraint you had left to not sob. Your legs were shaking to the point of humiliation and you whimpered under your breath as he licked you through your orgasm.
You gasped for air as you finally stopped shaking so profusely, running your trembling fingers through the locks in your hand. You slowly opened your eyes, blinking away the tears of pleasure that had formed without you knowing. Sukuna bear crawled over your meek frame so he could once again gaze down at you, a hand cupping your cheek. He captured your lips with his own and you could taste yourself on him. Slightly tangy, subtly sweet. A small, breathless moan escaped you and he pulled away, thumb caressing your cheekbone.
“Good girl”, he praised, voice endearingly gentle. You felt your eyes water once more, unsure of why. His thumb caught a stray tear. Your eyes fluttered shut as his warmth enveloped you, pressing your back to his front in a possessive manner.
As much as he would love to fill you up completely with his cock and make you forget how to speak everything except his name, he wanted to take his time with you. You were simply too much fun and it would be such a shame to indulge himself too quickly. He wanted you to come to him next time. Preferably on your knees, asking for him specifically. It was such a bother having to let Itadori initiate.
“My sweet princess”, he whispered against the shell of your ear. A shiver raked its way down your back and your heart swelled.
His princess, you thought as you drifted to sleep.
