part two | part three

You spotted his car before you even made it to the front door.

Parked along the curb beneath a streetlight, clean and familiar.

Good.

That meant he was already here.

The music from the frat house rattled the pavement beneath your heels as you stepped out of the Uber, smoothing your hands down the sides of your outfit before glancing at your reflection in the dark window of his car.

You'd spent nearly two hours getting ready for tonight, and not because you were excited about the party.

No.

You were here because your ex was.

Petty? Maybe.

But after two months of watching him parade around campus with his new ‘girlfriend’ like the last two years had never happened, you felt entitled to a little pettiness.

The front lawn was already packed with people. Music poured from the house through open windows and the constantly swinging front door while groups of students crowded the porch with drinks in hand. Laughter drifted across the yard, mixing with the smell of alcohol, weed, and cigarette smoke lingering in the warm night air.

You looked toward his car one more time before lifting your chin.

Tonight was about making sure he regretted it.

You weave your way through the crowded side yard, careful not to twist an ankle on the uneven gravel. The deeper you move into the party, the louder everything becomes.

Music blasts from speakers somewhere near the house, vibrating through your chest while groups of people crowd around folding tables and lawn chairs scattered across the backyard. Strings of lights hang overhead, casting a warm glow across the sea of students packed shoulder to shoulder.

Your eyes immediately begin searching for a familiar head of pink hair.

When you finally spot him, you nearly laugh.

Of course.

You watch Sukuna as his arm candy practically hangs off him, clinging to his bicep like she paid for the privilege. He stands at the end of a long table watching a group of underclassmen frantically play flip cup.

Empty cans and half-finished drinks clutter every inch of the table, and judging by the way everyone around them is yelling, this is less of a game and more of a public humiliation ritual disguised as entertainment.

You couldn't care less.

You didn't come here just to stand on the sidelines.

You make a beeline towards him, people parting around you as you move through the crowd.

They knew who you were.

By the time you reached the opposite end of the table, several of the players had already noticed your arrival. A few glanced between you and Sukuna with poorly concealed curiosity, while others openly stared, their attention drifting away from the game entirely.

News traveled fast in Greek life after all, and your breakup had been very, very bad, and very, very public.

It had only been two months since the two of you imploded at Tau Kappa Epsilon's start-of-the-semester mixer, and judging by the looks you were getting, nobody had forgotten about it.

You certainly hadn't.

The entire night had started with you watching Sukuna make his way through the party, surrounded by girls.

At first, you'd ignored it.

Then, you'd tolerated it.

Eventually, we were out for blood.

What started as a few sharp comments quickly turned into a screaming match in front of half the fraternity, and shortly after, you were throwing empty liquor bottles at his head while he tried to snatch you up and drag you to his car.

The argument continued all the way back to your dorm. Neither of you had ever been particularly good at fighting fair, and once the two of you got going, there was no such thing as a line that couldn't be crossed.

Every insecurity, every bad habit, and every mistake either of you had ever made became ammunition. By the time he pulled into the parking lot, you were both angry enough to say things you couldn't take back.

You told him you were done with him.

Then, because hurting him suddenly seemed more important than just walking away, you told him you were sleeping with your RA.

The lie worked far better than you'd intended.

At the time, you'd expected him to react the way he always did. You figured he would disappear for a few days, cool off, and eventually find his way back to you.

Instead, he vanished completely.

For an entire week, you tried contacting him. You texted, called, showed up outside his classes, stopped by his apartment, even waited outside his job, hoping to catch him before he left.

Every attempt ended exactly the same way, with him ignoring you.

Eventually, you stopped trying when he started showing up to places with another girl, a mere 10 days after your split.

You tried to convince yourself you didn't care.

That delusion lasted right up until you saw her wearing a gold bracelet he'd bought for you. You'd left it behind out of spite, never imagining he'd ever hand it over to somebody else as if you had never existed.

That was when you really began to spiral.

For weeks, mutual friends had been telling you that Sukuna hated you now and never wanted to see you again.

Maybe there was some truth to that, maybe there wasn't.

Either way, you had never truly believed he was indifferent. You knew Sukuna too well for that.

Your relationship had always been toxic.

The constant fighting, jealousy, breakups, makeups—none of it was healthy, and neither of you had ever pretended otherwise. But for all the damage you'd done to each other over the years, there was one thing you'd never doubted.

Sukuna was utterly and completely obsessed with you.

And judging by the way his attention locked onto you the second you stepped in front of him, completely ignoring his new girlfriend, you had a feeling he wasn't nearly as over you as he claimed to be.

You cross your arms as you both look at each other.

His expression had darkened significantly since you arrived, and you could feel the rage radiating off of him in waves.

The girl attached to his arm says something to him, but he doesn't take his eyes off you.

Instead, he scowls.

“The fuck are you doing here?” he asks, giving you a deadly look.

“I didn’t know I wasn’t allowed to have fun.” you roll your eyes. “Besides, I’m here for him.”

You nod toward the guy standing beside Sukuna.

The vice president, Jacob, immediately points at himself.

“Me?”

You nod and offer him a small smile.

“Yeah. You said you were gonna give me a tour of the house, remember?”

The lie leaves your mouth effortlessly, and to nobody's surprise, he goes along with it without question, his face immediately breaking into a grin as he straightens slightly, clearly pleased by the attention.

“Yeah, of course.”

You have to stop yourself from laughing.

Around you, the backyard is still packed with people. Music pounds from the speakers mounted beneath the patio roof while groups of students crowd the banister. The flip cup game finally continues in front of you, players shouting over one another as beer splashes across the table, but your attention remains fixed on Sukuna.

Or more specifically, the girl hanging off his arm.

She presses herself against his side, her manicured hand wrapped around his bicep while she smiles up at him. Every now and then, she leans closer to say something in his ear, and every time she does, that ugly feeling in your chest twists a little tighter.

You knew there would be other girls after the breakup.

You weren't stupid.

Still, seeing one draped all over him while he stood there looking completely unbothered by it made your eye twitch, especially when you notice that damn gold bracelet that hung off her wrist.

Your bracelet.

“Were you still offering?” you ask, turning your attention back to Jacob.

“Absolutely.” he smirks and steps towards you.

You step around the corner of the table and slip your arm through his.

The gesture is small, but you immediately see the effect it has. Sukuna's eyes drop to where your hand rests on the poor guy's arm before slowly lifting back to your face. His expression doesn't change much, but you've spent too much time with him not to notice the tension that settles into his posture.

The girl notices it too.

Her smile falters slightly as she glances between the two of you, suddenly looking a little less confident than she had a moment ago.

“Ready?” Jacob asks.

“Lead the way.” you smile.

As he begins guiding you through the crowd, you allow yourself one last glance over your shoulder. Sukuna is still watching you, his attention fixed entirely on you.

Exactly what you wanted.

You let Jacob pull you through the large house, showing you random memorabilia and supposed sacred artifacts of TKE, before he leads you upstairs.

He pushes through the door to his room and holds it open for you, stepping aside so you can walk in.

“And this is my cave.” he smiles at you, his dimples popping out under the dim lighting.

“Hm.” you walk in and run your fingers over his bookshelf.

“Sooo.” he rocks back and forth on his heels. “Wanna fuck?”

You snort and snap your gaze towards him.

“No.”

He nods his head and purses his lips as a semi-awkward silence falls over you.

“You’re tryna make Sukuna jealous, right?” he asks you.

You raise your eyebrows at his directness.

“Yeah.” You don't bother lying. It's not like he was going to do anything about it anyway.

Jacob shakes his head and lets out a breathy laugh as he closes the bedroom door.

“Yeah, I figured,” he says with a lazy smirk. “Hopefully he doesn't kill me.”

“Yeahhh.” You give him an apologetic look. “Sorry 'bout that.”

“It's fine.”

You wander further into the room while he leans against the door, giving yourself an excuse to look around. Compared to the rest of the house, it feels strangely normal. The music downstairs is still loud enough to vibrate faintly through the floorboards, but it's muted here.

A desk sits beneath the window, covered in textbooks, notebooks, and empty energy drink cans. Fraternity shirts are draped over the back of the chair, and a collection of figurines and random trinkets crowd the shelves lining one wall.

You sit down on the edge of his bed and reach over to pick up one of the figurines sitting on his nightstand.

“Your room is a lot cleaner than I was expecting.”

Jacob laughs as he pushes himself away from the door.

“Were you expecting a pigsty or something?”

“Yes.” you set the figurine back down.

“You're really honest.” he says, eyeing you.

You snort. “I know someone who would disagree with you.”

“I think I could probably guess who,” he chuckles. "I've heard stories about you.”

“Figured." you mumble as you look at your nails.

“I heard about all the shit you did to Sukuna.” he grins. “You're kind of crazy.”

“You have no idea, kid.” you sigh and clasp your hands together in your lap.

His grin only grows.

The conversation slows after that as you lean back on your hands and glance around the room again. Through the open window, you can hear groups of people moving through the backyard below, their voices drifting upward alongside the music.

The string lights hanging over the patio cast a warm glow across the room, and every few minutes, another burst of cheers erupts from somewhere outside whenever somebody wins a drinking game.

“I think it's hot.”

“Is that so?” you roll your head to the side to look at him.

Jacob shrugs, though the faint redness creeping up his neck gives him away.

“Yeah.”

You let your eyes drift over him openly.

He really is cute. Not enough big muscles or tattoos for your taste, but he looked clean-cut in a way most of the men you found yourself attracted to never were. His hair is slightly messy, his sleeves pushed up to his elbows, and despite trying to act confident, there's still an obvious nervousness lingering in the way he carries himself.

“I guess we could make out if you want.”

Jacob blinks. “Deadass?”

“Yeah, fuck it.” you pat the empty spot beside you.

He crosses the room immediately and sits down next to you. The mattress dips beneath his weight, and the closer he gets, the more obvious his nerves become.

His shoulders are stiff, his hands uncertain about where they're supposed to go, and he keeps glancing at you before immediately looking away again.

“Why do you look so weird?” you ask with a laugh. “Have you never kissed someone before?”

“Yeah,” Jacob says, rubbing the back of his neck. “but no one as hot as you.”

The answer is so genuine that you can't help smiling.

“Just relax. I'm not gonna hurt you.”

He lets out a nervous laugh and nods.

“Okay.”

You shift slightly toward him and watch him swallow. The sounds of the party continue around you as you lean closer. Music hums through the walls, voices drift past the bedroom door, and somewhere downstairs, somebody starts shouting the lyrics to whatever song is playing.

When your lips meet, he freezes for half a second before finally kissing you back.

The kiss starts slowly. You can practically feel him figuring it out as he goes, growing more comfortable each time your lips meet.

Eventually, he relaxes enough to slide closer, one hand settling against your side while yours moves up into his hair. The nervous energy he'd been carrying around all night gradually disappears as the kiss deepens.

You barely notice the footsteps in the hallway at first.

People had been walking past the room all night.

It isn't until they stop directly outside the door and nearly swing it off its hinges that either of you pays attention.

You both pull apart immediately.

Jacob's hand drops from your side while yours slips from his hair as you look toward the doorway.

Sukuna stands there.

The hallway light spills in behind him, casting part of his face in shadow, but you don't miss the crazed look in his eyes. His gaze moves from you to Jacob and then back again, locking in on your frame, taking in the sight of the two of you sitting together on the edge of the bed.

Jacob looks between the two of you nervously.

“Hey bro... we were just—”

“Shut the fuck up.” Sukuna doesn't even glance at him.

His eyes remain locked on yours.

You stare right back.

The tension settles over the room so quickly that it almost suffocates you. Jacob is looking increasingly uncomfortable the longer the silence stretches.

“You know it's rude to interrupt people who are about to fuck.” you smirk.

Jacob nearly chokes. “W-We weren't— Sukuna, I wouldn't—”

“I said shut the fuck up.” Sukuna finally turns his head toward him. “Or do you want me to break every bone in your scrawny body?”

Jacob immediately goes silent.

Sukuna's attention returns to you. “You. Get up. We're leaving.”

“Yeah, fuck no.” you cross your arms over your chest and lean back slightly. “Who the hell do you think you're talking to?”

The muscle in his jaw jumps.

For a moment, neither of you moves.

Then, Sukuna crosses the room.

The distance disappears so quickly that you barely have time to react before his hand closes around your arm. His grip is firm as he pulls you to your feet, forcing a startled curse from your lips while Jacob immediately stands.

“Bro, chill—”

“Sit down.”

Jacob sits.

Immediately.

You would laugh if you weren't busy trying to wrench your arm free.

“Sukuna, let go of me.”

“No.”

“I'm serious.”

“So am I.”

You glare up at him, but he doesn't budge. If anything, his grip tightens as he starts dragging you toward the door. The music grows louder with every step closer to the hallway, while students pass by outside completely oblivious to what's happening inside the room.

“Sukuna!”

“Keep walking.”

“You are actually insane.”

“Yeah?” he finally looks down at you. “And what does that make you?”

You keep your mouth shut at that, because unfortunately, you both already know the answer to that question.

Still gripping your arm, Sukuna drags you into an empty bathroom at the end of the hall.

He all but tosses you inside before he slams the door shut behind him and locks it.

“The fuck is your problem?” you growl, rubbing at the spot where his fingers had been digging into your skin.

His jaw is clenched so tightly you can see the muscle twitching beneath his skin, and the veins running along his forearms are noticeably raised from how hard he's balled his hands into fists.

“You wanna tell me what the fuck you were doing with my vice president's tongue down your throat?” Sukuna asks, standing between you and the door.

You drag your eyes over him and almost smile.

The calmness in his voice only makes him look crazier.

“Uh, like I said, we were about to fuck before you barged in like some angry caveman.” you reply with a roll of your eyes.

“You think it's okay to fucking embarrass me like that in front of the whole frat?” Sukuna takes a step closer. “I'm their president. How do you think it makes me look when my batshit fucking crazy ex shows up and starts drooling over every guy she sees?”

“I don't give a shit about how you look,” you scoff. “and why do you care who I sleep with? I'm not your girlfriend.”

A humorless laugh escapes him as he drags a hand down his face.

“Oh, so that's what this is about?” he asks. “You're mad I don't want your ass anymore?”

The smile on his face doesn't reach his eyes.

“I don't care what you want or don't want.” you cross your arms over your chest. “We both know I have no issue getting whoever I want. Half your frat would probably get on their knees for me if I asked.”

“See, that's your fucking problem.” Sukuna points at you as he takes another step forward. “You always think you're the center of everything. Always convinced everyone is obsessed with you.”

He gives you a cruel smile when he stops right in front of you.

“But the truth is that without me, you fade into the background,” he says, his voice dropping lower as he stares down at you. “Because there is nothing interesting about you. You're just another fucking slut who happens to have a pretty face.”

For a second, your stomach twists painfully, but then you look at him standing there breathing hard enough that his chest is rising and falling beneath his shirt.

His hands are still clenched, shoulders still tense. He still looks one wrong word away from punching a hole through the bathroom wall.

And suddenly the whole thing feels ridiculous.

“Then why are we here, dear king of frats?” you ask, tilting your head as you look up at him.

Sukuna's jaw flexes. You watch his eyes narrow, but he doesn't answer.

Instead, he stares at you while the music downstairs continues vibrating faintly through the floor, and voices drift past the bathroom door.

The silence lasts long enough for you to know you've hit a nerve.

Because really, he knows you're right.

If he didn't care, he'd still be downstairs. If he were really over you, he would've let Jacob have his little tour and stayed with his girlfriend.

Instead, he'd marched through a house full of people, dragged you out of another man's room, and locked the two of you in a bathroom because the idea of you touching someone else made him lose his fucking mind.

“That's what I thought,” you say softly.

The corner of Sukuna's eye twitches. The look he gives you is murderous.

Good.

You want him angry.

Jealous even.

You want him to feel every miserable thing you've felt for the last two months.

“You're unbelievable,” Sukuna mutters.

“Yet here you are.” you glare at him.

The words barely leave your mouth before his hand closes around your jaw, causing your breath to catch. His grip isn't gentle.

Neither of you wants it to be.

For a second, he just stands there staring down at you, his thumb pressed against your cheek while anger, frustration, and something far more desperate flickers behind his eyes.

Then he pulls you forward and crashes his mouth against yours.

You kiss him back immediately.

The kiss is rough from the start. Your lower back hits the counter with a sharp thud as his free hand grips your waist. Every ounce of tension that had been building between you explodes at once.

Your tongues slide messily against each other as he brings both hands to grip your ass through your dress.

You pull away to smirk at him. “You missed me, huh?”

“I fucking hate you.” he growls out before crushing his mouth against yours again.

You reach a hand down between you two to slide it into the waistband of his joggers, his growing bulge jumping in your hand, causing him to groan loudly.

“You sure?” you reach down further to cup his heavy balls in your palm, “Your dick seems to say otherwise.”

You give him a toothy grin that's laced with pure sadism.

His jaw hardens noticeably, but he allows you to feel him, his eyes never leaving yours. He’s always been known for his cocky attitude and brutal nature, yet he stands there, letting your pretty hands wander wherever they wanted like you own him.

His breathing hitches, barely audible under the muffled noise of the party downstairs.

You lick your lips as you slowly watch his composure crumble under your touch. You bring your hand back up to wrap around his girth, stroking him slowly as he grows to full mass.

“You think you can control me with a few touches?” he breathes out.

“I know I can, baby.” you blink up at him, fluttering your lashes just the way you know he likes.

A low, dangerous growl rumbles from his chest—his cock visibly twitching under your palm in agreement despite his pride trying to fight it. He reaches a hand up to grip your chin again, harder this time, forcing your face closer to his.

“Get on your knees.” his voice is barely above a whisper, deadly and dangerous.

You look at him with lidded eyes, arousal and yearning swirling around them as you speak.

“No.”

His pupils dilate as they watch the smirk tugging at your lips.

“I think you need to earn it.” you say.

He growls, the sound low and satisfied as his eyes lock in with yours. He knows exactly what you’re hinting at, and he’s willing to show you just how badly he deserves it.

With a sudden movement, he turns you around, pressing your hips into the cold counter and pulling up your dress. He groans as he notices you aren’t wearing any panties.

“God, no panties? Dirty girl.” he reaches down to run his fingers through your wetness.

You let out a breathy moan as he drops to his knees behind you.

He doesn't hesitate. His hands grip your hips like a vice, pulling them back until your ass is perfectly presented in front of him.

“Lean forward.” he presses a large hand against the center of your back.

You immediately oblige, your arms reaching out to brace your weight against the counter.

He spreads your cheeks before he buries his face between them, his tongue immediately finding that tight, pouting heat he’s been dreaming about for months.

He groans against your flesh, his eyes closing in bliss as his tongue drags slowly up your slit.

You let out a shaky breath, your arms trembling as they already struggle to hold up your weight.

His tongue drags along the center seam of your ass, not caring about the slight hair there. He braces one hand on your hip, the other curling around your thigh to hold you in place.

“Stay still.”

He begins to eat you out slowly, but deeply.

You sigh as your knees knock together at the sensations overwhelming your core.

He grips both thighs now, forcing your knees apart with his palms. His tongue spreads your folds, tasting your arousal like it's the sweetest nectar.

He groans against your skin, his grip tightening possessively. His eyes are closed in concentration, giving you the attention he always reserved only for you.

“Spread wider.” he commands.

You shuffle your feet further apart, opening your core up for him more.

He rewards your obedience by diving deeper, his tongue plunging into you with a wet, obscene sound. His chin presses against your clit, the friction driving you wild.

“Oh fuck…” you whine as your head falls forward.

He uses his thumbs to spread your cheeks even wider apart, giving him full access.

There he was.

The self-proclaimed frat king on his knees, worshipping your sweet pussy like it's his only reason for existence.

“Kuna.” you pant out as you feel his tongue slide in and out of your hole.

He curls it inside you, mimicking his cock as he eats you out desperately. Slick sounds fill the bathroom as he works you open, his breath hot against your dripping folds.

One of his hands slides up to pull the front of your dress down, exposing your tits before he grips one firmly.

“Mm, your pussy missed daddy, huh?” he murmurs against you before sucking your clit hard between his lips.

You jerk forward at the sharp pleasure.

“Yes…fuck yes, baby…” you moan as you grind filthily back onto his face.

He growls against your clit, the vibration making your thighs shake violently. He keeps his grip on your soft mound of flesh, his fingers pinching and twisting the stiff peak as you grind shamelessly against his mouth.

His tongue swirls around your sensitive bundle of nerves before sucking it back in ruthlessly, the wet slurping noises echoing off the walls and shooting right back into your core, making your quivering hole leak all over his nose and chin.

“Missed every fucking inch of this messy, fucking cunt.”

He pulls back to spit directly on your pulsing clit before he dives back in to lap at your slick entrance.

“Oh shit! K-Kuna…” your legs can barely hold you up at this point. “I-I’m gonna fuckin’ cum, baby.” you moan as you grind harder against him.

Your hole clenches violently as drool and slick drips out and down your puffy lips.

He swallows, his tongue catching every drop with a slow, deliberate suck. His eyes roll slightly at your words, the smell of your arousal and taste of you on his tongue overwhelming him.

“Good girl, fucking cum all over my tongue.” he sets a steady rhythm, trying to give you that last push you need to fall over the edge.

“Ohhhh baby…just like that..” you moan as your breathing turns into rapid pants, your entire pussy burning as the pleasure begins to pool. “Gonna cummmm.”

His ego swells with pride at your pleasure, his tongue making bolder, more aggressive movements against your swollen, hard clit.

He spreads your cheeks wider, almost pulling them taut as he fully sucks your wet folds entirely into his mouth. He runs his tongue over them as he slurps them up, his eyes fluttering closed as he laps up your juices like a man dying of thirst.

You gasp as your body slowly stiffens, your hole clenching violently around nothing as your orgasm builds tighter and tighter.

“S-So close…” you whimper out, your face pressed onto the counter as you squeeze your eyes shut.

“Cum for me.” he growls out as he pulls away slightly, his tongue flicking rapidly over your clit. “Make a fuckin’ mess for me.”

He dives back in to suck your whole pussy back into his mouth, swirling his tongue up and down, back and forth through your heat.

Your orgasm hits violently, your twitching slit gushing wet streams directly onto his face and tongue. He catches every drop with absolute devotion, mouth moving rhythmically against you, guiding you through your trembling release.

“Kuuunaaa fuuckkk yes!” you moan loudly into your arm, your body locking up as you grind your achy, leaky cunt all over him.

He doesn’t pull away as he swallows your fluids, not stopping until you're shaking from overstimulation.

Once finished, he presses a wet, open-mouthed kiss to your swollen clit before standing and pulling himself from his joggers.

You're still panting as he grips the base of his cock and rubs it against you.

“I’m gonna fuck this tight fucking pussy so hard.” he groans as he rubs his precum over your slick entrance.

Right before he can sink into you, you stand and pull your dress down.

“Huh?” he looks genuinely confused as he watches you adjust your dress back over your chest.

You sigh and turn on shaky legs before planting a kiss on his clothed chest.

“This was fun.” you smirk up at his confused expression.

You can practically see the wheels turning in his head as he tries to figure out why you look like you’re about to leave.

Before he can think too long, you flash him a smile and unlock the bathroom door to step back into the hallway.

He watches the door shut behind you, his cock in hand and a stupid look stuck on his face.

You smirk as you walk down the stairs and towards the front door.

Yeah, he’s not going anywhere.

need him BAD
