THE LIBRARY WAS the last place (y/n) thought to look for answers but, she in large part blamed that on her generation. She sat in the center of the large library, century's old books stacked from floor to ceiling. She couldn't remember the last time she came here, to be completely honest she actually avoid this place like the plague.

It aways made her feel slightly uncomfortable, the smell of old books and burning candles just rubbed her the wrong way.

"Why can't I find anything?! Ugh! "

She slammed her forehead on the old oak desks, open book's surrounding her as she flipped through trying to find answers to her questions.

She had gone through the history of jujitsu, the different types of diseases of jujitsu and the history of Sukuna Ryōmen just for kicks. This little library journey was shaping up to take all day.

Just then out of the corner of her eye she spotted an untouched book at the very bottom of her stack. Its purple velvet cover, binded with gold threads, it seemed to be perfectly preserved.

Upon closer observation the title read; " sorcerers and curses, the bonds between us."

The title made (y/n) skin crawl, yet relief swept through the girl. Finally, it seems like her search had come to an end. Flipping open the book, she ran through the table of contents. Skimming through her finger hovered over a word the made her heart lead out of her chest, "soulmate bonds pg. 256"

Quickly flipping through the book her words seemed to be caught in her throat, disbelief the only thing going through (y/n)'s mind as she read the chapter.

"theses individuals may feel confused, the symptoms usually start as dream sharing, followed by burning and intense sexual urges. The later symptoms can present as sharing each-others pain and memories-"

Her heart throbbed in her ears, she couldn't even breathe.

"The only way for these symptoms to stop is to complete the soul binding, to mark their chosen half. There are several benefits to this, sharing jujitsu and power reserves. Additionally, the sorcerers life is extended to match the length of the curse..."

"But if the soul binding is not complete the curse will eventually die and the sorcerer will lose their ability to summon cursed energy..."

(Y/n) felt her eyes water, hot tears beginning  to leak out.

"Not much is known about this affliction, there are few cases of soulmates over the case of centuries. Each case has been between an extremely strong curse and powerful sorcerer..."

Feeling herself hyperventilating laid her head on the table. This can't be happening, this can't be happening, this can't be happening!

Her (e/c) hues went to read the last paragraph when she realized parts were scratched out and illegible.

"There is one known way to remove the soulmate bond, it is though-"

God dammit!!!

This couldn't be happening to her, it couldn't. Not with her clan breathing down her neck, and being a sorcerer. Her job is to exorcise, kill curses! Not fall in love with them.

Crying tears of frustration (y/n) repeatedly slammed her forehead on the desk, "why me..."

Closing her eyes, she hadn't realized how tired she truly was. All her energy had run out, exhaustion had taken its hold on the young women.

why me?

•••••

WAKING UP TO Sukuna's domain of eternal damnation and torment could cause anyone to feel dejected, but the 1000 year old curse couldn't help be feel hurt by (y/n) reaction to his presence.

Her (e/c) orbs opened only to lock eye contact with his red hues, causing her to audibly grown.

"Not now Sukuna, not now"

She rolled onto her stomach and just stayed there not wanting to come to grips with the information she just learned.

"What's wrong with you?"

The pink haired man became frustrated at her attitude, grabbing her roughly at the waist as he flipped her onto her back. Without regard to her feelings he straddled her, pinning her thin wrists above her head. His devilish smile causing heat to pool between (y/n)'s legs.

"Tell me (l/n)... why are you acting like this?"

It wasn't that he didn't find her actions amusing, in fact it was quite the opposite. Her childish nature only made him want to teach her some manners.

Lowering his head, a glaze passed over his scarlet hued eyes. Feeling bold, he tightly held her in place as he traced her neck with his tongue. She gasped at the sudden hot contact, rubbing her thighs together due to the dripping liquids from within.

Her eyes fluttered closed as she savored his lapping tongue, the butterfly kisses and bites he haphazardly littered all over her collar bone and up her neck. What caused her to truly react was when the curse carefully bite hear ear lobe, his hot breath driving her over the edge.

"Tell me little lamb I won't ask again"

He moved so his one hand held two of her wrists, his now free right hand wondering underneath the hem of her skirt.

(Y/n) bit her lip at the contact, she wanted to tell him what she had learned but she didn't want this to stop. She didn't care if it was fate binding them together, all she knew is that she wanted this.

His tattooed fingers played with the waist band of her pink panties. With a sharp thwack he pulled them and released, making (y/n) audibly gasp.

"Tell me (y/n), unless... you don't want me to stop?"

He purred her name, his honey combed voice sending shivers down her spine. Instead of responding, she just whined at his touch.

Sukuna was a beast, he took what he wanted and now he wanted (y/n).

In one clean montion he ripped her underwear off, pulling her school skirt with it. This action left her lower waist bare, now only wearing her black button up and bra.

"Ah- Sukuna!"

She moaned his name as he ravished her. He greedily licked and sucked her dry, lavishing her cunt with his rough tongue. His tattooed long fingers pumping her, making her stomach knot.

"Ah don't stop"

He savaged her, as if he was a starving man who hadn't eaten in weeks, he became a heathen. He would be the first to admit, she was delicious.

Absolutely addicting, and he couldn't get enough.

Something about her made him lose all sense of self, he drowned in her. Sukuna was certain he could never get enough.

In lavishing her cunt he released her wrists, now pinning her voluptuous thighs wide open. Her fingers shot to his hair, as she moaned in please. She pulled and grasped onto his pink locks as if her life depended on it. His tongue swiping up and down her hot sex, plunging in and out bringing her closer to the edge. His sharp fangs light grazed her clit, her audible gasp make the curse grin. He calculating circled his tongue  around her hot pulsating pleasure, driving her made with desire.

"Sukuna ahh, Sukuna!"

She couldn't get enough, she was in a haze. All she could think, all she could feel, all she could breath was him.

Her high was building, and he could tell. His tongue now pumped her as his talented fingers rubbed her now swollen cunt rhythmically. He feverishly indulged in her leaking juices, making her slim thighs slick with passion.

"Right there! Don't stop!"

In an instant the knot in her stomach came undone, as she rode her orgasmic high. Sukuna lapping up all her juices, greedily, drinking in her addicting nectar. He loved it, how she tasted on his tongue. Its all he wanted, all he craved.

She instinctually grabbed a fist full of his pink hair, holding on for dear life as she rode his face. Her high seemed never ending, it was euphoric.

Pulling away quite whimpers left (y/n) pouting pink parted lips. Hot whines leave her pretty mouth, as she desperately wishes for more.

"So are you going to tell me what's on your mind?"

Look at Sukuna through her thick full lashes, a lustful haze still present on her (e/c) hues.

"We're soulmates... that's whats on my mind."
