Your heels clicked loudly on the stained prison tiles. The echo of your soft footsteps trailing along the narrow walls of the enclosed hallway.

Sukuna.

That was the prisoner you were assigned to. A man who had killed more people than you’d met in your entire life as a doctor, a psychologist at that. So you’d met a lot of people.

Two guards trailed closely behind you, glaring warningly at the inmates who smirked as you walked past the line of cells. A collection of whistles and cheers sounding at the mere sight of a woman as attractive as yourself.

How long had it been since they’d seen one after all.

“Hey Doc… you sure you wanna take this case.. i mean, i don’t doubt ya or anything but this one.. he’s bad. Dangerous.”

“Now what kind of doctor would i be if i feared a little danger. He’s still a patient.” You smiled, ignoring the way your hairs stood as you were led deeper into the institution. The part where they held those deemed a danger to society.

Those who had a no chance of even seeing sunlight again.

You were nervous, your heart thumping loudly in your chest when you scanned your surroundings. There weren’t any cells. There were only.. rooms. Fully enclosed rooms with a singular window for passing food.

Every part of your being begged for you to turn around and run. To not even interact with whoever sat on the other side of that door. And you froze when bright red eyes pierced into yours. The rest of his face casted behind a dark shadow as his head tilted back. Giving you sight to the small smirk creeping onto his features.

“Doc, i really think that-” It was the other guard who spoke up. Both of them holding nothing on their features but fear. It was clear that they never even bothered with Sukuna. The rumors had been enough to make every guard turn a blind eye.

“Hey, it’s fine. Okay? This is what i do.” It really was. The guard gave you a curt nod and a sigh when you clasped both his hands in your smaller one. Offering him a reassuring nod.

“If anything happens, us and about five others are stationed close. Good luck Doc.”

You gave him a small thanks, your head held high as the door was pulled open roughly. Revealing a pink haired man who sat on his bed against the walls, his eyebrow raising when you dared to step inside. Nodding to the guard to close the door.

You might as well have been a dead woman.

“You’re scared.” His deep voice rung out, keeping his eyes on you as you pulled out a small chair that was tucked away near the sink.

“And how do you know, Sukuna?” Your tone was steady, letting out a breath when the shakiness you felt wasn’t reflected in your voice.

Sukuna hummed, his smirk widening when you spoke to him like a normal being. To stuttering, no harshness. Just your sweet voice saying his name. “I can smell it, Doc.” He loved the way you tried to hide your squirm under his gaze.

“So, Sukuna. Tell me something about yourself.” You steered away from his accusation, holding eye contact even when he leaned forward. Taking you in from head to toe. You were hot, he liked that. You seemed to like being confident too. And God did you smell fucking delicious.

He wanted to eat you alive.

Break you.

Use you.

He really did. But you were so fascinating, and he’d only just met you. Who knew how entertaining you could be.

“I’ve killed people.” He was blunt, eyes almost begging you to keep asking these ridiculous questions. It was making his cock twitch.

“Well Sukuna, that is common knowledge, don’t ya think? I wanna know something else.. tell me a secret hmm?” You leaned forward with a smile, elbows rested on your knees as you looked to him for a response.

He reciprocated your actions, leaning forward until you felt his hot breath fan over your face. “A secret huh? Alright Doc..” he watched as your breathing sped up, using every strength in your body to not pull back. You were brave, he liked that. “I surprisingly don’t wanna kill you right now.”

“I’m glad to hear that.”

“I said right now, didn’t say anything about later.” He pushed away from you, one of his knees up to his chest when he leaned back against the concrete wall behind him. “Let me ask you, Doctor. Are you stupid?”

Your head tilted at where this was going. You were supposed to be the one asking the questions. But a conversation was two sided, this would’ve made things easier. “I’d like to believe not. Why do you ask?”

“Because you really think that if i try to kill you, some measly guards would come to your rescue.” He scoffed.

“But you don’t want to kill me. That’s all that matters.”

Fair.

Sukuna watched as you took a quick peek down at his files. There was something that you missed, that much was evident. “Finally found it huh?”

“I haven’t found anything that i didn’t see before.” You objected, glancing to the door with your lip hanging loosely between your teeth.

“Don’t. Don’t do that.” He demanded lowly, watching with lidded eyes as you let your plump bottom lip, slick after running your tongue over it, fall back into place. Sukuna breathed deeply, finally looking away from you as he swallowed hard. Closing his eyes with his head rested behind him.

There was something about you that he wanted a taste of. It was driving him crazy..er, “I never did anything to these other doctors. They were just weak. Got scared way too fast.”

“And what did you do to scare them away?”

“Nothing.” He spat, “They came in here acting all high and mighty, talked to me like i was beneath them. So i simply didn’t bother to hide how much i wanted to strangle them. And somehow that makes me the bad guy right Doc?”

You shook your head, “No, you have a right to respect too. They should never have treated you as unequals.” Lying was all in the job description.

“Good try Doc. But you and i both know that’s a load of crap.” He finally peeled his eyes back open, and you couldn’t help your mind from wandering to how attractive he was in the dim light. He was extremely built, and had the facial structure that made you clench your thighs. “Now, we gonna finish our game of twenty one questions or not?”

He was actually being cooperative.

“Yes we are. How about i start?”

“I’ll start.” There was no room for objection in his tone. “What’s your name?”

You contemplated whether to tell him or not, eventually letting it out with ease. Though you missed the small smile tugging at his lips when he muttered a small “cute.”

“My turn, what was your childhood like?” You watched his face grow cold, a small glare being directed at anything in the room but you. “Next question.”

“Sukuna..”

“I said next question. How old are you?”

You sighed, “I’m twenty eight.” His eyes widened, that was extremely young for a doctor. “Is there one good memory you have from before you killed for the first time?”

“I had twin kittens. Do you have a boyfriend?”

You were taken aback by the question, mouth opening and closing a few times before you chuckled. “No. I do not have a boyfriend.”

“Good.”

You jumped when the door was yanked open, the guard eyeing Sukuna warily before nodded to you. “Your time’s up, Doc.”

“Oh, already? Could we get just a few more minutes?”

“You know how dangerous he is Doc.. we can’t risk it.”

“You heard the man. I’m dangerous, Doctor.”

You nibbled at your lips softly, and Sukuna fought a groan as you did exactly what he warned you not to. Standing up, you gave Sukuna a warm smile, the gesture making his stomach get all weird inside. “Goodbye until our next session Sukuna.”

He only hummed, the door being shut behind you as you were led away.

It was back to darkness.

There was more than enough light, sure. But it suddenly felt so empty without you there.

—

You couldn’t keep Sukuna off your mind when you arrived home. A part of you just really wanted to figure him out. The other actually liked his company.

You must’ve been so sick in the head. Splashing your face with cold water as you mentally scolded yourself. What was wrong with you? He was a criminal.

—

The next morning you walked the path that you had taken the previous day to get to Sukuna. This time without the guards following you.

There was only one who stood outside of the door to let you in with a small nod of acknowledgement.

Sukuna’s head perked up at the familiar clicking of those heels you wore. His signature smirk on his face as he stared you down. “Just couldn’t get enough huh Doc? Aren’t you forgetting that i’m dangerous?”

You took a seat, no file in had this time. “Good morning Sukuna, how are you?”

“If i said better now that you’re here, would that be cliché?”

You laughed, an actual laugh. A sweet one that made his heart flutter the tiniest bit while blood rushed to his groin.

“It’s very good to see you too. How about we get started yeah?” You paused as you collected your thoughts. “You seem to be heavily affected by people calling you.. dangerous. Why?”

“Everybody is dangerous. It just takes pushing at the right buttons to get it out of them. Half of the people here have done just as bad as i have yet i’m the only dangerous one. Makes so much sense right?.”

He shook his head. “Tell me Doctor, do you really think i just happened to get caught? That i couldn’t get out of this damn place if i wanted too? Hell, tell me you realize that i could drop a good twenty more bodies right here, right now.”

You shifted in your seat. “I think that you let yourself get caught because you’re tired. Because there’s a small sense of peace you get from being in here. And i think that you aren’t trying to leave because you don’t want to.”

“You almost had it Doc. See, i was well on my way out until you came. So i might stick around for just a little bit longer.”

Your heart fluttered, for you? Giving up on fighting the rational side of you as you continued to engage in conversation. Getting Sukuna to slowly open up to you more.

“Do you have any friends Sukuna?”

“I don’t consider people friends. They just exist alongside me.”

“If I asked you to be your friend, what would you say?” It was routine, but you really were curious.

“I’d say you came be whatever you want to be Doc.”

Another flutter.

“Have you ever been in love Sukuna?”

He was silent, jaw clenching as his gaze got harsh. “Next question.”

“What was she like?”

“I said next fucking question Doctor.”

“And i said, what was she like?” You leaned forward, pressing for him to answer the question.

“You’re stubborn aren’t you? I wonder what my hand would loom like around that pretty little neck.” He grinned, sharp teeth peeling from beneath his lips as he brought his face to yours. “She was a lot like you.”

“What happened to her?” You knew how touchy that question would’ve been.

“Nothing. The bitch left.”

Oh.

“I’m sorry.”

He stared at you in confusion, “I never said she died.”

“Yes. But that’s only physically. When she broke your heart she died to you. And that hurts just as bad.”

He was silent, studying your eyes. Trying to get a read on you. “What else do you want to know Doc?”

You were getting somewhere.

Sukuna found you smart. Thought that you knew a lot. Found it hot how good you were at cracking him. But it pissed him off that the one thing you didn’t seem to pick up was how much it hurt to watch you leave at the end of each session.

—

A week later had led to a Monday morning where you hadn’t gone to the prison. You had quite an agenda for the day that could cost you your job if you didn’t get it done.

That was something Sukuna was obviously clueless about. It was why he thought you’d just decided to up and go after he had just started liking to have you around. After he’d started opening up to you.

It was also why he was causing a fit. Yelling at guards to get you to him now. That he wanted to see you. Needed to see you. A line of men laying knocked out atop each other from being sent to ‘handle’ the crazed prisoner.

Would you really not come back? Would you really abandon him? It seemed like that was common with the people he cared even the slightest for.

Sukuna’s fist met the wall near his bed, knuckles bloodied as he cracked into the hard surface. Chest heaving up and down heavily when his hands reached to tug at strands of pink.

He blinked when he heard the clicking of heels on the tiles. Immediately scowling at the unfamiliarity of them. “Who the fuck is this?” He growled through the small window.

“This is Dr Smith, she’s-”

“I don’t fucking care who she is. Bring me my doctor. Now.”

—

Back at your flat, you dropped the piles of paper in front of you at the sound of your phone ringing.

It was a number you didn’t have saved.

“Hello, Doctor ___ speaking- yes? Oh my. I- i am so sorry. Yes, i will be there right away.”

What had you done?

You practically ran through the halls after parking outside the building. Finding many guards posted outside his door with guns in hand. Some of them spotting very black and blue eyes.

“You can all go now.” You panted, it was clear that you had been in a hurry. “Please.”

They all shared a look, finally walking away and allowing you to slowly open the door.

“Where were you?”

“I’m really sorry Sukuna. I was so busy today and-” you gasped when a hand reached out to wrap around your neck. Slamming you into the wall behind you with his face buried in your neck.

Sukuna inhaled your floral scent, groaning to himself as his grip on your delicate skin tightened. “So you just left me here today? Am i not as important as your other little patients? Is that it hmm?”

Deep down, you had hurt his feelings. And he couldn’t help the way he clung to you as your hand lifted to his cheek. Turning his face to look down at yours.

“N-no i promise you. You’re just as important as anyone else. I would have never missed our session if i didn’t have to.”

“Make it up to me.”

It was the perfect opportunity.

“W-what?”

“Strip for me Doctor.” He let go of your neck, letting you catch your breath while looking up at him timidly.

“Sukuna..”

“Why so shy now doctor? We both know you want to.”

You shook your head, shrinking under his gaze with a protesting whisper. “I don’t know what you’re talking about Sukuna. This is very unprofession— ahh.”

Sukuna brought his knee up between your thighs, pressing it into your clothed clit. His lips ghosted over your ear, hot breath fanning your skin as he breathed deeply. “You can always leave if you want to. I’m used to that after all.”

You shifted on your feet when your back arched. A small whine leaving your mouth when he pulled away from you and gestured to the door.

He smirked, “Blouse first.”

You bit your lip, unbuttoning your shirt until your bra was on display. The heavy swell of your breasts causing Sukuna’s mouth to water when he nodded to the bra.

With your eyes still on his you let your breasts spring out of their confinement. Two pert nipples pointing right at him as his dick rose. His hand palming himself under the pair of black pants with a shiver. “C’mere.”

You walked over to him on shaky legs. Sitting down on his lap with your head to the floor. “Uh uh,” His hand reached under the your chin to force your eyes back on his. “None of that Doc.”

You moaned when his tongue swirled around one of your nipples. Sucking your breast into his mouth while he palmed at the other. “These are even more perfect outside that tight fucking shit of yours.”

Sukuna watched as you shivered when he ran his finger down your belly. Cupping your clothed cunt with the jerk of his hips into your ass. “Fuck.. take that off.”

You hurriedly peeled off your pants, Sukuna’s pupils dilating at the sight of your lace panties. “Wore this just f’me hmm Doc? All this for Mr Dangerous.” He groaned out.

Sukuan didn’t give you a chance to respond before flipping you onto the hard mattress they called a bed. Lifting your heel clad feet onto his shoulders with his head hovering over your pussy. His tongue darting out to lick at the wet spot building from your arousal. “You’re real dirty f’ a doctor.” He teased, glancing behind him with a chuckle. “Imagine if you got caught.”

Your eyes shot up to the small window, taking note of the vacant corridor as per your request.

“God, you smell so fucking good. Wanna devour that pretty pussy.” He breathed, large hand ripping the flimsy fabric to expose your glistening folds. “Hmm, this wet all for me.”

You mewled when his long tongue licked a stripe up your slit. Swirling around your clit before sloppily dipping into your hole. His hums sending vibrations through your clit as he lapped at your dripping slick.

“Sukuna—” you mewled, back arching as you reached for his hair. Tugging softly with the curl of your toes when his tongue and fingers swapped places. The two joints fucking up roughly into your g spot as he sucked noisily at your clit. “F-fuckk, nngh— so good.” You cried out, tears welling in the corner of your eyes as your body filled with pleasure.

“Yeah? You like that Doc? Bet you wanna get that greedy cunt stuffed right after.” He grunted, your eyes rolling back in a string of muffled moans as your other hand shot up to your lips.

Your legs began to tremble, Sukuna’s smirk growing wider and wider until he stopped his movements. Watching as you blinked down at him with a sniffled whine.

“You left me. You know how much that fucking hurt? I thought i would never see you again.”

“I’m-”

“You’re sorry. Yeah, yeah.. i know.” He rolled his eyes, crawling over your body with a sigh. Using the pad of his thumb to wipe away a stray tear before pressing his lips to yours. Making you taste yourself on his tongue.

You fell deeper into the kiss, eyes closing in satisfaction as his lips moves hungrily on yours. Pulling away with a string of salvia connected you to him.

“Let’s reverse the roles yeah?” He whispered, standing up to sit in the chair that you usually sat in. “So, my adorable little patient.. put these tiny fingers to work on that clit of yours. I want you to make yourself cum.”

You whimpered, your fingers immediately meeting your sensitive clit with a shiver.

“You know what to do.” He encouraged. Your fingers beginning to rub small circles on the small bud before speeding up. Little gasps and moans falling past your lips as your stomach burned with heat.

Your eyes locking onto Sukuna’s red ones as his head tilted. Just like it had the first day you met him. “Ahh, K-kuna. Fuckk.” You cried, head falling back with your eyes still on his. The primal look in his eyes making your insides flutter as he did nothing but watch you. Not even freeing his painfully hard cock.

“Sukuna— c-can’t. Can’t hold it.” Your voice cracked, body shaking lightly as your orgasm washed over you.

“Yes you can.”

“Nngh, can’t Kuna. Need to let go.”

He stayed quiet for what felt like an eternity, your breathing getting heavy as you desperately waited on his permission.

He leaned his head back, eyes boring into your fingers working your wet cunt before nodding. “Go ahead.”

You came with a silent moan, body spasming uncontrollably as your pussy leaked onto his only pair of sheets.

“Dirty, dirty girl. Look at that mess.” You shied away feom his gaze. “And look at how hard you made me. Come fix it.”

You stood on wobbly feet, barely able to balance in your heels as you fell to your knees before him. Looking up at him through your lashes while pulling down his pants.

You blinked at the mere size of his bulge. He was huge. Tugging off his underwear to reveal his thick, veiny length. Pointing up to the sky with a fiery red tip. “Suck.”

You took him past your lips, barely able to take even half of him before he hit the back of your throat. Your fist stroking all the parts of him you couldn’t take.

Sukuna groaned, head flinging back with another strained one at how good your mouth felt. “S-shit doc. You really got a mouth on ya.” He gasped, eyes meeting yours as you attempted to take him down your throat. Your drool coating both your lips and his cock as you lewdly sucked him off.

He took your head into his hold, letting you do your own thing as he grunted with each jerk of his hips. Defined abs tensing when he grew closer to his release.

“Fuck Doc, gon’ shoot my cum down that tight throat of yours.” He breathed. Holding you down onto him as you gagged and sputtered lightly, Sukuna’s cock twitching before you felt the warm liquid run down your throat.

“Wish i could fuck that pussy so bad.” He let go of your head, wiping a drop of his cum from your chin before pushing his finger past your lips. Watching as you sighed in content while sucking every last drop. “It’s too bad that in about one minute those guards are gonna come get you Doc. Our session is over.”

You had no time to question how he knew. Scurrying to redress with widened eyes.

Sukuna may not have had a clock. Nor was he able to distinctly see the sun rise and set. But he’d learned to count the seconds when you were around. He knew how much time he had with you.

“And… now.”

At that very moment the door swung open. Sukuna having easily pulled back up his pants after giving you your seat back. Both of you looking as professional as you possibly could.

“See you tomorrow Doc.” He smiled innocently, watching as you scrambled out while avoiding his eyes.

You really fucked up now.

It was hard to keep him out of your mind before. But now, trying was futile. You’d gotten a taste and you needed more. Which was why your brain would not let you close your eyes without thinking of him fucking you.

—

The next morning you bit back a whimper as your clit was caught between your rubbing thighs. You had worn a tight pencil skirt with no panties. Just for Sukuna.

You were thankful that the guards had complied to your wishes of them leaving.

You wanted to stop yourself. To go back home and forget about the red eyed prisoner. He may not have been dangerous to you physically. But to your heart and mind.. he’d be the death of you.

When the door closed behind you, you found yourself bring pushed roughly into the same wall as last time. Sukuna letting out an animalistic groan as he captured your lips on his. Kissing you so much more feverishly than yesterday.

“You don’t know how much i need you. Didn’t even sleep last night.” He panted, turning you around so that your chest rested against the concrete surface. “Missed you so much Doc.” His voice softened, kissing down your neck while grinding up into you. His fingers finding their way under your skirt with a smirk against your skin. “And i thought you couldn’t get any dirtier.. no panties huh?”

You moaned when he prodded at your already dripping cunt. The thought of him being enough to have gotten you soaked. “Shit- tell me what you want Doc. Let me hear you say it.” He growled lowly, ready to snap the second the words left your mouth.

“Please— please fuck me.”

Sukuna hungrily shoved your skirt up. The fabric bunching at your hips as he freed his aching cock. Both of you letting out a noise of satisfaction when he sunk into you, his large hands holding tightly onto your hips to pull you into him. Your back arching as your hands shot out to the wall for support.

“O-ohh God.” You cried loudly, your lips parted in shaky moans as Sukuna’s cock rammed deep near the entrance of your cervix. His veins grazing at your g spot as the fat girth stretched you to your limit.

“Nah baby, ‘s only me.”

“Kunaa— so goood- ahhh.” Tears pooled in your eyes, Sukuna’s hand reaching into your hair to pull you back into his chest. Your nails clawing at the wall in front of you as he destroyed yours.

“Taking me so fucking well. Shit- pussy’s so damn snug.” He husked, hips snapping noisily into yours as he fucked into your walls mercilessly. Basking in the sounds of your choked screams and mewls. The way you sobbed underneath him when your knees buckled.

He was fucking you so hard and deep. Better than anything you’d felt before. His cock slamming into all the places that would drive you crazy.

“The day you fucking leave me i will break outta here Doc. And i will find you. You’re mine got it?” There was a certain seriousness in his voice that made goosebumps arise on your skin. Your salty tears mixing with your drool as they ran down your flushed face.

“And when i do get outta here you’re gonna have my baby Doc. ‘M gonna fuck you again and again till’ i eventually give you my fuck—ing kid.” His breathing became ragged, your body rocking forward with each of his movements.

He smirked. “I’ve fucked ya this dumb already?” His cock twitching inside you as your body moved with his cock like a fleshlight. Your vision blurred as your head grew light, dizzy. You couldn’t think, every roll of Sukuna’s hips clouding your mind as you let an incoherent babble drip off your tongue. Shakily chanting his name when he reached forward to pinch at your clit.

“Look at you. Look so pretty underneath me like this.” His free hand snaked up to your neck, groaning loudly at the feeling of your heart beat on his skin. Pulling you up so your back rested flat against his broad chest, wandering lips meeting your exposed collarbone. “Let go f’me.”

Your body quivered as you tightened around him. Letting out a whimper-like cry as you came messily on his cock. A breathy moan of his own sounding in your ear when his thrusts began to get sloppy.

“Kunaaa.. inside. Want you inside. ‘M on the pill.” You begged, legs giving way as he held you flush against him.

“Whatever you want, Doc.” Slowly coming to a halt as he buried himself inside your warmth, tongue darting out to lick at your tear stained cheeks. Feeling his cock swell as he pumped you full of his cum. Painted your gummy walls in nothing but white

“Looks like i’m sending you back with my cum dripping down your thighs.” He pulled out with a grin. His cum leaking out of your fluttering cunt in small spurts when he used his hands to knead at the flesh of your ass. “Hottest thing i’ve seen in a while.. after you of course.”

You hummed, eyes shutting as you fell into him. Feeling the thick substance slowly dripping down your legs while spreading over your sticky folds. Sukuna stumbled back onto his bed with you on top of him. Your face nestling into his chest with a soft smile. “Hey Doc.. i love ya but those guards are gon’ be back soon.”

‘So worth it.’ Was the one thought branding itself into your mind as your body registered the rough, lust filled fuck.

“Shit.”

—

You and Sukuna had gotten so much closer over yet another week. You had never believed in falling in love that quickly until now. You couldn’t help it. You felt so much better when he was around. Seeing him was the highlight of your day- especially now that you’d convinced for longer sessions.

He felt the same way. You were the second person he had fallen in love with and somehow even harder. You made his heart.. swell. And he was serious about busting out to start a life with you.

“So, your first love. We never finished talking about her.” You smirked, notepad back in hand as you did your job. Sukuna having been stealing small kisses from you between every question.

“How about we forget about my first love and focus on my current one. You.”
