BEGINNING OF REVISED DRAFT
When Yasuko awoke, it was not to the empty white walls of her bedroom at the institute like she had expected. No, instead she was met with something else entirely.
Ominous red light cast this far larger room into shadow. She felt strangely weightless as she stared out into the darkness, almost as if she was floating somehow while she waited for her eyes to adjust. When they did, she was finally able to make out the massive ribcage looming above her. The giant, vaguely humanoid, ribcage. A lack of support beams as she glanced around the room suggested it was the only thing keeping the roof from caving in.
She squinted up at it. Sure, she’d seen a lot of strange things over the years dealing with curses, but even by their standards this was… an interesting decorating choice.
She shuddered in displeasure, closing her eyes as she reached up and brushed the hair out of her face, a drop of water sliding down her cheek like yet another useless tear.
Wait.
What?
She sat up quickly, sending ripples out around her in the process.
The whole room had about a foot of what appeared to be blood sloshing around it.
…and she’d been lying in it this whole time.
She grimaced as if in pain.
How lovely.
“Well that’s fucking nasty,” she hissed aloud, scrambling to her feet. She tried to get her bearings as she shook herself off like some deranged dog.
It was eerily silent apart from the sound of her splashes. The fact that the liquid seemed to slip off of her instead of being absorbed by her clothes didn’t help with her unease.
A glance down revealed she was still dressed in her uniform from her mission earlier.
How strange.
She was pretty sure she remembered changing out of it after she got back to the dorms, only just managing to throw on one of her oversized t-shirts instead before she collapsed Into bed feeling exhausted and miserable.
So she was definitely dreaming then, right? She glanced around the room, considering it from this new perspective.
…
She wondered what this said about her mental state.
…
Probably not anything good.
…
Anyway,
She reached up and tucked her hair back into where it had come undone from her braid, fingers snagging on a tangled curl in the process and yanking her scalp with a sharp jolt of pain. Narrowing her eyes, she laughed nervously.
This dream felt awfully realistic.
Ignoring it for now, she glanced around, checking for anything she might have missed between the blood and the ribs and the-
That was when she noticed the giant pile of bones.
She froze as she tried to figure out what they were from. Whatever they were, they definitely weren’t human. They were far too misshapen and large.
‘I mean sure.’ She thought detachedly, giving up on trying to figure out why everything was the way it was and just accepting that this was her current reality. ‘This might as well happen.’
She’d been having nightmares since Satoru’s disappearance, but honestly? This was getting ridiculous. What, was her subconscious manifesting a place that looked like Hell supposed to represent her feeling of living in it? She didn’t exactly need a dream book to figure that one out. How annoying.
She sighed in disgust, kicking at the strange liquid.
Forget the dream book. She was deciding right now that this was actually just her subconscious’s way of telling her to... drink more cranberry juice.
...Yeah.
That sounds right.
She watched the dark liquid lapping at her feet for a minute warily.
A cough from above startled her, and she nearly slipped and fell back in.
Oh, so there was a throne up there, too.
Sukuna, the demon that kept trying to possess Itadori, the thousand year old jerk whose musty fingers they kept making her go on missions to retrieve so that Itadori could then scarf them down like Takis, The King of Curses, glared down at her from atop it menacingly. His head rested against his fist as he lounged on the skulls of his innumerable felled enemies, lips curled in that threatening smirk that always made her feel something slightly to the east of anger.
She stared up at him heatedly for a second. And then another second, admiring the cut of his jaw and sweep of his hair and overall formidable presence.
...Nice.
What the hell was he doing here though?
Her stare drifted off into confusion before the pieces finally started to click together, finally realizing that this place was actually probably his domain, not just some random nightmare hellscape dreamed up by her subconscious.
Well, that explained why she felt so lucid, at least.
She glanced around again wondering if she’d missed anything.
A cursory glance around the room informed her that she hadn’t.
She raised her eyebrows at him questioningly. So this was all him, then.
“Really?” She suddenly asked, deadpan.
Sukuna just stared back, his smirk falling slightly as her non-reaction apparently threw him for a loop. He’d definitely expected her to either cower, scream, or just launch into an attack immediately but… Why should she? It wasn’t like she was really there, and anyway, she didn’t have any ridiculous assumptions that she could beat him outright in his domain, no less.
“Really what?” He replied, feigning boredom.
“Your domain is just... tons of blood and bones? Don’t you think that’s a little cliché?”
He frowned.
“I mean,” she looked down dubiously again at the ‘blood.’ “This. This is just blood, right? It’s not like piss or something and the red lighting is just making it look different-”
“What do you want?” Sukuna growled.
Yasuko paused, eyes flicking back to him in interest. Was that his angry voice?
…She kind of liked it. An idea of what she might want to do once again crossed her mind but was quickly ignored in favor of a far more pressing concern.
“How did I even get in here?” She asked incredulously. She certainly hadn’t just waltzed in uninvited. Was he somehow amassing his strength again despite still being sealed away? Without the rest of the sorcerers knowing? Without Itadori even knowing?
Sukuna shifted on his throne. She narrowed her eyes in suspicion.
“You probably drifted in here while sleeping.” He said eventually, glancing off to the side. “Wandering souls are occasionally attracted to my domain at such close quarters.” He grinned slowly then, as if he was just now coming to a realization upon seeing her red-rimmed eyes. “Particularly restless and sad ones.”
She gazed back at him unimpressed, not believing a word of it. When she woke up she’d definitely be mentioning this to Nanami. As weird as explaining “this” would be.
Hopefully on the condition that he couldn’t tell Nobara, though. She’d be insufferable if she ever found out Yasuko was sharing dreams with The King of Curses, ugh she’d never let it go. It’d be just like the “maybe he isn’t so bad” comment she’d made when he almost sniped Mahito all over again. “Acknowledging a good deed isn’t endorsing him, Nobara, yes I know he’s still evil, no I’m not suddenly into him now just because he attacked the curse I hate.”
“Missing someone?” he asked mockingly after her lack of response.
Her face turned impassive, whirling thoughts coming to a halt. “...Maybe,” she conceded.
They stared at each other in silence for a minute, during which she looked him up and down, considering. Ruthless, heartless curse or not… he was here, and Satoru was… gone. She’d cried almost every night the past month like she was still some teenager with their first crush, and she was so tired of it.
It’s what she’d been doing before she’d somehow ended up here; passed out again at 3 in the morning, cuddling a jacket of Gojo’s she’d stolen from his room.
She sighed, running a hand through her hair. She’d let herself get far more attached to him than she’d wanted to. Apparently his winning personality, and the whole “strongest sorcerer,” schtick had deluded her into thinking that he would stick around longer. She should have known better with their line of work. This was why she didn’t get attached to people. It’s why she had trust issues.
She grit her teeth as a sudden wave of self-loathing gripped her. She couldn’t protect him, she couldn’t protect hardly anyone of a higher rank than her. She was just some mid-ranked sorcerer that everyone knew was only good for spying and ambushing with her silencing ability. She hated being so weak. No wonder Gojo was so distant at times, always hesitating to define their relationship despite it clearly being far more than just friends at this point, even ones with benefits. Friends didn’t constantly initiate and melt into kisses outside of sex, friends didn’t constantly follow her around buying her things that reminded him of her. Friends didn’t lay for hours wrapped up in one another, talking about a possible future together where maybe they could manage just enough of the elder’s crap and do just enough to prevent the world from ending so that maybe one day, someday, they could both try and escape the fate of so many sorcerers to die young and alone.
They’d both been so lonely.
They’d both lost so much.
And yet he’d gone and left her, gotten himself killed, anyway.
There hadn’t even been anything left to identify him by. There rarely was, in the case of curses. And if he was still alive he definitely would have turned up by now.
She straightened again and eyed Sukuna thoughtfully.
He had asked her what she wanted. What she really wanted, right at this moment, was to stop thinking for a while. To stop feeling so cold, and empty, and... and lonely, for just. Just a moment. She hadn’t been able to get that once since he’d left, any semblance of peace having shattered long ago.
She wanted a distraction more than anything right now.
Watching the way his eyes raked over her in a similar manner, she thought that maybe she could get it.
She knew she was pretty, at least. She’d never had a shortage of admirers from either gender.
Besides, she had always been attracted to him whenever Itadori had let him out for a few minutes. His confidence, his easy yet powerful movements in battle, his voice, how he was always tearing off his shirt- She glanced down at his white kimono. She knew he had some killer abs under there. And really nice back muscles and biceps. And strong, broad shoulders- yeah ok she was doing this.
“Sukuna…” she drawled, beginning to stalk towards him through the mystery liquid. It splashed but made no sound around her feet.
He raised an eyebrow at her in question, before abruptly scoffing in distaste as he realized why she was getting closer.
“What, did you finally muster up the urge to fight me?” He rolled his eyes as he leaned back against his throne, before staring down his nose at her skeptically. “Do you really think that’s a good idea-”
“Tell me,” she continued coyly, cutting him off. “When was the last time you’ve been with a woman?”
He stilled, his eyes widening slightly as he was clearly taken off guard. His hand froze in midair where he had lifted it to make some kind of gesture.
He didn’t respond for a moment. Slowly, he relaxed again, lowering his hand to instead grip one of the horns of his throne. His eyes followed her movements more closely now as she neared him. She put a little more sway into her hips as she noticed his sudden interest.
“...Why do you ask?” He said eventually with suspicion.
“Just curious.”
She grinned flirtatiously up at him from under her eyelashes as she reached the bottom of the hill of bones.
He hummed, his expression still guarded.
“I was just thinking,” she paused, glancing up at him before continuing. “That you probably get pretty bored in here all by yourself and well, I wouldn’t be opposed to a... distraction. For a bit.” She trailed off as he leaned forward slightly, attention fully on her now. He propped his chin on his hand as he considered, pretending to think it over before side-eyeing her.
“You’re really offering yourself to me?”
He grinned conspiratorially.
“Isn’t that a little traitorous, sorcerer?” he mused.
“It’s not that traitorous,” she replied, before amending “Not if it was only for a night. If you were interested, that is.”
She looked back down finally, trying to keep her balance as she climbed up the hill. Worried about snagging her tights or accidentally impaling herself if she wasn’t careful, her attention was momentarily elsewhere. She was surprised to look up and find him standing near the edge as she reached the top, offering her a hand.
When she grasped it, he pulled her up and then farther still into his arms.
“I’m interested.” He murmured, face inches from hers.
Sukuna was far more intimidating up close. Those ruby eyes stared at her like a wolf facing down its prey. Daring her to make the first move and follow through with her suggestion.
Cautiously, she reached forward, laying her free hand on his chest. Immediately she felt the firmness beneath it. She blushed, but managed to keep a neutral expression as she carefully continued to explore.
He was solid muscle, definitely more built than Satoru, with a bigger, more solid frame.
She shivered in arousal and the slightest stirrings of fear as she glanced up at her natural enemy again. He was still watching her, eyes dark, permitting her intrusion. He could snap her wrist like a twig if he wanted to, dream or not. And yet, for some reason, she didn’t think he would… right now, anyway. Not while they were both playing nice. She let her hand glide up to his scarf, glancing at him for assent. He didn’t move to stop her as she gently tugged it free, letting it fall from her fingertips to the bones below.
Gradually, his grip on her arm lessened as she grew more bold, lightly grazing the column of his neck as she reached up to card her fingers through his hair. Her eyes widened briefly before softening, pleasantly surprised by the soft texture. His grew half-lidded as she lightly scratched his scalp, carding her fingers through the strands. He let out a low hum of approval.
She eyed the skin she had exposed earlier by removing the scarf, biting her lip. Her hand slowly dropped back down to tease at the edge of his kimono with a finger, pulling lightly as her eyes flicked back to his playfully.
“Aren’t you bold.” He muttered reproachfully despite the same amusement flickering in his eyes.
She blushed harder, her eyes meeting his in coquettish challenge as she reached up and quickly removed her own scarf. She pulled her long braid over her shoulder, and tugged it loose to let her hair cascade freely down to her waist.
“Better?” She asked quietly.
Sukuna leaned in towards her neck then, closing his eyes. She stiffened, worried for a second at having him so close to such a vulnerable spot, but he merely tangled his hand in her hair and breathed in deeply, inhaling her scent as he drew even closer. She knew she smelled like jasmine flowers and wood smoke. The smell of the incense she burned often lingered on her skin.
“Much,” he exhaled against her, the gust of air making her ticklish.
She couldn’t help the shiver it sent down her spine.
She looked at the throne behind him consideringly. It didn’t look very comfortable, but it’s not like they had much of a choice in here. She was absolutely not about to get it on in the mystery liquid below. She rubbed the fabric of his kimono between her fingers, mulling it over. Maybe they could use their clothes to cushion it.
Sukuna licked at her neck.
Or she could just ride him.
He nibbled at the tender skin under her ear.
She frowned at the thought. She didn’t really want to do all the work though.
He bit her abruptly, harshly, and she let out a soft moan in surprise before covering her mouth and stiffening against him in embarrassment.
She could feel his self-satisfied smirk at her reaction, before he started to nurse the skin he’d just bitten, soothing it.
Her breath hitched, and she returned her hands to his kimono, delving inside it to caress his bare skin. He was so hot against her fingertips. She watched, transfixed as he shivered just barely. She wondered briefly if he was ticklish too. He felt human, even though those eyes of his made it obvious to everyone at first glance that he wasn’t.
She wasn’t sure why that surprised her. She’d killed plenty of humanoid curses. They were, after all, born from human resentment. It made sense they’d take after them.
She gently pulled the kimono open wider to reveal more of his shoulders and those strange, striking markings. She traced a few curiously for a moment, then began to unbutton her own top before Sukuna could grumble again.
The air was cool on her skin as she removed the cloth, dropping it too, to the pile below. She hesitated to take her bra off, and in her moment of indecision he sliced it off instead with sharpened claws. He tossed it to the ground below before his hands came up to fondle her breasts as he bit lightly at her collarbone. She noticed that his claws were retracted once again. Interesting.
She pulled his hair in rebuke even as she let out a low sound of pleasure. “You know, that had a clasp,” she hissed in annoyance.
He ignored her. A hand came up to grip the hair at her nape, holding her in place as his lips grazed along her jaw. She met his gaze again. She was startled at how hungry it looked. Her eyes dropped suddenly to his lips, her tongue sliding out to wet her own. He paused, watching it intently, before placing his lips firmly against hers. Her eyes slid shut as she wrapped her arms around his neck and pulled him in, adjusting to a better angle. She licked at his plush bottom lip greedily, coaxing him to deepen the kiss. His lips parted, and suddenly she felt out of her element as his hot tongue delved into her mouth, twining against her own. He kissed her like he was starving, and she hummed in contentment as she carefully slid her tongue across his sharp canines, melting further against him. She pulled away a moment later at the feeling of him starting to tear at her skirt.
“Sit down,” she whispered against his lips, a thin string of saliva still connecting them.
He paused, his eyes unreadable, before reaching down and lifting her up in a bridle carry with an arm beneath her shoulders and knees. He walked them the remaining few feet to his throne before he settled against it. Then he leaned forward, attempting to capture her lips once more.
She pressed her hand against his mouth, which he promptly bit. She hissed in pain.
Yanking it away, she said quickly “Wait, just let me-”
He ignored her, pressing his lips against hers once more insistent. She sighed against his mouth. His hand came up to tug at her hair again, tilting her head back for better access. She cracked open her eyes, only to find him staring lustfully at her in turn. She nipped at his tongue. He jerked back, grunting, before his crimson eyes opened fully to glare at her as he growled threateningly.
She panted, nearly breathless. “Just let-”
She twisted out of his grip quickly, stumbling away. He grabbed her arm before she fell, despite remaining seated.
“Where do you think you’re going?” He inquired, his voice edged with something dangerous.
She pulled at the hem of her skirt pointedly in answer, slowly teasing the fabric down her hips.
He released her with obvious reluctance. She made quick work of her remaining clothes, turning around and kicking them off to sail to another part of the bone pile. His hands grabbed her from behind, pulling her towards him with ease. She turned as she was pulled towards his lap, bracing herself with her knees to either side of his hips. She looked down briefly from her position above him, brushing a strand of hair back from his face before she settled down fully against him. His hair was rumpled, his lips reddened, and his kimono tugged half open exposing his shoulders and well defined chest. He was tempting, and his eyes promised vengeance if she withheld her kisses for much longer. She licked her lips, leaning in to instead kiss the corner of his mouth with a smirk. She could feel him harden further beneath her as his hands settled heavily on her hips, encouraging her to grind against him. His lips chased hers, but she turned her head, and he kissed her cheek. He narrowed his eyes at her mischievously, fingers sneaking into her hair again. Grinning, she pressed her palms against his chest as she was dragged back down into another kiss.
Slowly his hand left on her hip trailed lower, cupping a cheek and squeezing a moment before drifting down between her legs. Her breath hitched against his lips as he stroked at the wetness there. His eyes watched her attentively as he carefully inserted a clawless finger. She closed her eyes again as she dragged a hand through his fluffy hair, kissing him harder encouragingly. His finger began pumping in and out of her as he sucked on her tongue. She moaned when she felt him poking her thigh from below through the fabric. Her hands dropped to his robe again as she tugged it roughly open, exposing his pecs and biceps fully. Her hands stroked slowly down his chest.
He withdrew his hands for a moment to free his arms completely from the kimono. When he was finished he returned his slickened finger and immediately began adding another. She stroked down his abs teasingly, feeling the muscles jump beneath her fingers. She smiled as she finally gripped him through the fabric. He hissed, tilting his head back and breaking their kiss as he clenched his eyes shut briefly in pleasure. She stroked him, nibbling at his jaw as she rocked her hips back against his stilled fingers.
She closed her eyes and tugged his belt loose from its knot, finally exposing him to her. Grabbing his dick, she practically purred as she felt how big he was. She couldn’t even wrap her fingers fully around it. His hair tickled her face as she nuzzled him.
His fingers began to move again, his head returning to her neck as she pumped him gently. She reveled in the feeling, sighing in bliss. Oh, how she’d missed this. She raised a hand to cup his head and buried her nose in his soft hair.
She opened her eyes, and saw cherry blossom instead of snow.
Suddenly tears streamed silently down her face in rivulets.
Sukuna paused in his movements, feeling her tears slip down his neck. “Why are you crying?” he asked gruffly, lifting his head from her neck long enough to glance at her impassively as his two fingers continued working her open below.
She gave a bitter sigh despite the pleasure of his thumb rubbing her clit, meeting his gaze and smiling at him wryly.
“You must not be doing a good enough job of distracting me.”
His four eyes glowered at her as he pulled back slightly in offense.
She laughed, tangling her fingers in his hair. She gave a sudden harsh tug, causing him to grunt in surprise as she leaned in and growled against his throat “Come on, Sukuna, I thought you agreed to help me stop thinking tonight.”
She pressed a kiss against him then, and smiled teasingly despite the anguish still ripping at her heart.
“I mean If it’s really too much for you after all this time-”
His loud growl rumbled through her chest as he removed his fingers and flipped them, crowding her back against the throne. She moaned softly at the feeling. She briefly registered that he had left his kimono covering it. Huh. How thoughtful of him.
She hastily blinked away her tears. ‘Not now,’ she thought. Later, sure. She wouldn’t be able to hold this all in for a while yet. But she had already decided that she was done crying over Satoru tonight.
“Oh?” She whispered tauntingly, a smirk pulling at her lips “Was I wrong?”
He didn’t even dignify her with a proper response as he grabbed her by the hips, sliding against her wet heat as his head buried itself in her shoulder once again, biting hard. She let out a choked gasp before moaning at the feeling, her nails raking down his back in revenge as he slowly let go and began to suck and lick at the darkening mark.
He chuckled darkly at her response. “So you want it more like this?” He hissed, flexing his hand and dragging his own exposed claws down her sides slowly, leaving welts in their wake. She thrummed with anticipation, feeling a surge of excitement laced fear shoot down her spine as his heated gaze met hers.
“Yes please” she murmured distractedly as she felt his length press harder against her thigh. Any thoughts of Satoru suddenly shifted to the backburner again.
“Oh? So now you’re being polite?” He sneered at her, baring his sharp fangs.
She hummed contentedly, gazing at him through half-lidded eyes as she smirked. Her pussy throbbed as she clenched around nothing. “Oh yes. You have my full attention now. Do continue.” She said pleased, wrapping her legs around his waist and brushing a hand coaxingly through his ruffled pink locks.
He shifted slightly, pulling his hips back. His four eyes still glared at her, assessing even as his arms drew her more tightly to him before he stilled abruptly.
“Why should I?” He hissed menacingly. “Why shouldn’t I toss you out of my realm right now for your insolence?
She eyed him with amusement as he refused to move.
“Please Sukuna?” She asked, closing her eyes and lazily drawing circles on his back as she kissed his shoulder sweetly. She glanced at him again out of the corner of her eye as she spread her legs open wider in invitation.
“Please?” she whispered.
He thrust into her then suddenly, roughly, and she barely muffled another moan against his shoulder as he pulled back briefly before pressing into her more fully. She squinted as tears pricked at her eyes again from the stinging feeling of her body trying to adjust. But she didn’t complain, even if he could have stretched her out a little more. She was more than turned on and, well. She’d wanted it rough after all. She hissed at the sensations, pleasure mixing with the pain as she gripped him tighter. He easily fell into a shallow rhythm, her slick making the glide effortlessly smooth.
The throne was cool against her back as she was pressed even harder against it, a delightful contrast to the burning of Sukuna’s skin. She was right, his kimono and her hair barely made it tolerable. She couldn’t even begin to grasp how he supposedly sat in it all day. She panted as he began to pick up the pace, his thrusts getting deeper as his claws started to dig into her hips, making her flush hotly. Harsh smacking filled the air, the little gasps escaping her echoed by his occasional grunt as he buried himself in her over and over again.
“So wet.” He growled approvingly in her ear, licking a stripe up her neck before nibbling at her earlobe. She whimpered helplessly in pleasure.
One of his hands came up to play with her right breast, kneading and rolling her nipple between two of his large fingers. She clenched around him and he groaned.
His hand wandered down, leaving a trail of fire in its wake as he flicked at her clit.
She pressed her lips to his in a frenzied kiss, trying to drown out her embarrassing sounds against him. He licked his way into her mouth, before nipping harshly at her bottom lip. His sharp teeth sliced through her flesh easily, a quick, vicious reminder of just who she was messing with. She pulled back with a hiss, glaring at him.
He grinned unapologetically, his pupils blown wide with lust as his tongue darted out to lick at her blood staining his lips. She panted, feeling it start to dribble down her chin as he increased the pace of his savage thrusts.
He chased her lips again, his eyes smoldering as he licked and sucked at his bite softly. She whined, overwhelmed.
“Sukuna...” she pleaded, her arms tightening around his neck.
“What, sorcerer?” He growled.
“I’m close.” She whispered against his lips, grunting and gripping him tighter as she began to move her hips to meet his harsh thrusts.
Instead, he started to slow down. She whined in protest, immediately regretting telling him.
“Are you?” He asked breathily, his lips lazily twisting into a merciless grin as he continued thrusting into her at a slackened pace. His left hand’s grip on her hip became almost bruising to prevent her from moving faster as his right leisurely dragged up the back of her left thigh, grabbing the back of her knee and spreading her legs wider as he lifted it up to meet her chest. The shift in position allowed him to reach even deeper in her, something she hadn’t even realized was possible, making the head of him drag against her sweet spot with every thrust.
Her whines increased in volume as he did so, making her remove an arm from around his neck in a vain attempt to stifle them with the back of her hand.
His hand moved from her hip to snatch it immediately, his gaze suddenly turning harsh.
“What are you doing?” he demanded, stopping his movements entirely.
She groaned in irritation, squirming with discomfort.
“Sukuna, please” she begged.
“I asked you what you thought you were doing.” He growled, his crimson eyes flashing
dangerously, mere inches away.
“I-” She whimpered, biting her bruised lip before letting it go quickly with a wince.
“I was… embarrassed,” she admitted, eventually, defeated. She didn’t meet his eyes. “I don’t like being so loud.”
“Well, don’t be.” He murmured, eyes dragging down to her lips again.
“I like hearing your sounds.”
He met her gaze steadily. “And there’s no one to hear you scream in here anyway.” He smirked.
She stared at him in silence for a moment, before she hesitantly moved her hand back to his bicep, surprised when he let it go easily.
Slowly, he began to move again, gradually picking up to his former pace as he hiked her knees up further. Her soft cries flew past her lips unimpeded as he moved his mouth down to her neck, cleaned away the lingering trail of blood from earlier. He licked and sucked another dark mark below her ear when he finished, making her clench around him again as she hugged him closer, whispering incoherent praises into his shoulder. He groaned in pleasure as he began thrusting into her in earnest, gaining even more speed, which only resulted in him lightly panting against her neck.
She wasn’t sure if she should be thrilled or appalled at his stamina.
She was close. So close. She bit his shoulder, hardly making a dent in the rippling muscle. She groaned and dragged her nails against his back, struggling to get a better grip as they grew more slick with sweat. He was burning against her. With her head so close to his neck, she could finally smell his scent of musk mixed with something dark, and sweet, and heady. It could be addicting if she wasn’t careful.
His hand moved rhythmically against her clit as they both neared their peaks, liquid heat pooling low in her belly as his thrusts turned less refined, the both of them growing desperate.
He bit deep into her shoulder, his fangs piercing her skin this time. If she were in her real body, she'd definitely be worried about scarring.
She screamed, her claws digging gashes into his back as she suddenly came, choking on his name as she was overwhelmed with the warring sensations of searing pleasure and throbbing pain.
He pounded into her chasing his own release a second later, making her sob from the overstimulation and pain from her wound. Finally, he buried himself in her to the hilt, his hot seed spilling into her and leaving him lazily pumping himself dry as he groaned and let his head fall heavily onto her shoulder. He brought his arms up and hugged her to him tightly, still not pulling out even when he finally stilled, growing softer. She sighed in contentment at his warmth as their sweat started to cool on her skin, his hot breath fanning her neck.
He licked at the sluggishly bleeding mark, and she winced, her breath hitching in pain.
He stopped, before almost apologetically pressing a soft kiss to it, moving back down to suck and press kisses against her chest. She sighed, still dazed with pleasure, as she finally relaxed. She slowly carded her fingers through his soft hair.
“I take it back,” she murmured into his hair a few minutes later when she’d finally regained her breath.
“Hm?” He hummed detachedly, face buried in her chest.
“I was definitely wrong earlier.”
“Oh?” She could feel his cocky grin against her skin.
She started to nod tiredly then cringed, her hand lifting up to cup her wound before she stopped upon seeing the blood caking her fingernails.
“Oops.” She whispered in surprise. Then she frowned in concern.
“Shit I think I tore up your back, let me look.” She whispered apologetically, trying to squirm out of his grip. He growled loudly and she stilled, glancing down.
“Leave it.” He muttered, unmoved.
She slumped back in realization.
“Oh yeah you can just heal it… I forgot” She said quietly, feeling a little chastened. Sukuna wasn’t Satoru, afterall. He wasn’t even human. She vaguely recalled the others telling her that he’d been able to completely regrow Itadori’s hand and heart in the past. Before killing a special grade in seconds. Her scratches were nothing in comparison.
He hummed noncommittally.
“You know,” she teased, trailing a blood tipped fingernail along the tattoos on his shoulder blade.
“You make such a great partner for Pillow Talk.”
He grunted in annoyance. She giggled, sighing as she finally quieted.
Her hair laid tangled around her, barely softening the unforgiving throne against her back. She still had no idea how he supposedly sat on the thing all day like Itadori said. Maybe he just didn’t feel pain. She squinted, considering. Something seemed wrong with that logic, but then again, the rest of his domain was just blood and bones and that can’t be comfortable either. It wasn’t like he had many options. No wonder he was using her like a living cushion right now.
She snickered, continuing to pet him.
“What’s so funny?” He whispered darkly in her ear. She shivered with arousal.
“I just realized that you’re probably using me as a pillow right now because this place is so horribly uncomfortable.” She whispered.
He didn’t say anything.
“Oh my god you totally are-” she said accusingly, starting to laugh before it shifted abruptly to a moan as he shifted in her suddenly.
Forget getting ripped to shreds, his recovery time was going to kill her.
—--------
Yasuko woke up the next morning in her bed, in her room, far away from Sukuna’s Domain… to a searing pain in her neck.
She scrambled out of bed in her desperation to get to a mirror in the futile hope that it wouldn’t confirm what she already suspected to be true.
There between the junction of her neck and shoulder, sat a dark, lightly oozing bite mark, the teeth clearly too sharp and distinct to be anything resembling human.
…
