Sex | Sebastian Sallow x Reader

This fucking song and this fucking idea have been floating around in my head for months and I think I just gotta get it out before I go NUTS!!! I hope y'all enjoy.

This is... not very plot driven tbh, just pretty much longing and smut.

Words: ~9,200

The walk to the car is excruciating.

And it’s not because of the crowd, not because of the neon-lit chaos of the parking lot, or because people are weaving between cars, shouting to their friends, the leftover adrenaline from the concert still pulsing through everyone’s veins.

It’s excruciating because of you.

Because you’re tipsy and giggling, clinging to Sebastian’s wrist as you stumble over the uneven pavement in those ridiculous platform heels that you insisted on wearing even though you knew you’d be walking half a mile back to the car.

Because your top is tight—way too tight—clinging in ways that make his pulse skip, the fabric stretching over curves that he’s spent ten fucking years trying not to stare at.

Because your jeans are hugging your thighs like they were painted onto you, and he’s trying so goddamn hard not to think about how good they look, how good you look, how much better you’d look without them.

And then there's your makeup—the dark, sultry eyeshadow, the perfectly lined eyes, the lipstick that started out precise but is now just slightly smudged from sweat, from drinking, from running your tongue over your lips all night.

It’s killing him.

You laugh suddenly, squeezing his arm as you stumble again.

“God, my feet hurt,” you whine dramatically, pressing your forehead against his bicep like the weight of your suffering is too much to bear. “Why the fuck did I wear these?”

Sebastian snorts, steadying you easily. “I asked the same thing when I picked you up, love.”

You lift your head, squinting up at him, cheeks flushed from the alcohol, the heat, the pure, unfiltered joy of the night.

“They make me taller,” you say, lifting one foot and wiggling it mid-air for emphasis before dropping it back down with a clunk.

Sebastian shakes his head, amused but also distracted, too fucking aware of you tonight.

“You’re still short,” he mutters.

Your mouth drops open in mock offence and you shove him, but your balance is shit, so you just end up gripping his arm harder, your nails pressing into his skin.

Sebastian swallows. He feels everything—your warmth, your weight against him, the way your fingers curl slightly against his forearm, the way your perfume is mixing with the sweat on your skin, and fuck—

He clenches his jaw. Keeps walking.

You don’t let go.

“That was such a good show,” you murmur, your breath warm against his shoulder.

Sebastian swallows. Nods. “Yeah.”

Then you tilt your head up at him, narrowing your eyes.

“You’re being so quiet,” you tease, squeezing his arm. “Did you not have fun? You didn’t even get a single drink.”

Sebastian exhales sharply through his nose, smirking just enough to cover the fact that his pulse is pounding.

“Yeah, well. One of us had to drive.”

You laugh, nudging your hip against his.

“Responsible and sexy,” you tease. “God, you really are the whole package, aren't you?”

His throat goes dry.

You always do this when you're tipsy. You get flirty, bolder than usual, pushing boundaries you'll never fully cross. You say things, teasing, reckless things, that curl around his ribs and settle deep into the spaces between them. Things that would mean everything if he thought, even for a second, that you meant them.

But you don't. You never do. By morning, it'll be like it never happened.

You'll wake up, groggy and hungover, your memories softened at the edges, and everything you said, every look and every touch, will be reduce to a joke, and Sebastian will have to pretend it didn't mean anything to him either, just like he always does.

He knows this.

But tonight? Tonight, it’s harder to keep his head on straight.

Because you look like this. Because your boyfriend isn’t here. Because your fingers are wrapped around his arm, and your perfume is still lingering in his lungs, and you keep staring up at him like you’re waiting for him to say something. Like you’re daring him to say something.

Sebastian forces out a low chuckle, looking away.

“Let’s get you in the car, trouble.”

He unlocks it with a quick flick of his keys, grateful for the distraction, for something to do with his hands other than wrap them around your waist and haul you up against him.

He slides into the driver’s seat and barely gets the door shut before you’re groaning dramatically and stretching out.

“Oh my god,” you sigh, reaching down with clumsy fingers to unbuckle your heels. “I swear to Merlin, I think my feet are broken.”

Sebastian smirks, watching as you yank them off one by one, dropping them onto the floor with two loud, echoing clunks.

“Told you,” he mutters, reaching for his seatbelt.

“I don’t need your attitude right now,” you huff, kicking your feet up onto the dashboard before twisting to face him.

Then, before he can even register what’s happening, you shift—leaning over the center console, stretching yourself across his lap like you belong there.

His entire body locks up.

Fuck.

Your hair spills over his legs, soft waves spread over denim, the warmth of you pressed against him. You twist a little, adjusting yourself, completely oblivious to how every tiny shift of your body is undoing him.

Sebastian exhales sharply through his nose, staring straight ahead, gripping the wheel like it’s the only thing tethering him to sanity.

“You comfortable?” he mutters.

You hum, smiling lazily, your cheek resting on his thigh.

“Mhm.”

His pulse jumps at the sound, but you’re not even thinking about it, are you? You’re not thinking about what it means, or about how he can feel the heat of your body through his jeans, how desperately he’s trying not to not get hard right now, how much he wants—

He exhales sharply, tilts his head back against the headrest, and fights the urge to slam his fist against the dashboard.

This is going to kill me.

Sebastian puts the car in drive.

Your place is only twenty minutes out of town. All Sebastian has to do is survive you laying across his lap and not get pulled over for the blatant seat belt violation happening right now. Simple.

Except it’s not.

Because every time he shifts gears, he feels you. And every time he exhales, he catches the scent of your shampoo, and because your breath is warm through his jeans, your fingers idly tracing along his thigh like this is just something you do, something normal, something casual, something it absolutely isn’t.

Then you start talking, and part one of his mission—survive you being in his lap—becomes infinitely harder.

“You ever think about your exes?”

Your voice is light, teasing, and the question comes out of nowhere.

Sebastian’s grip tightens on the wheel. “Like who?” he mutters.

You hum, fingertips still lazily dragging patterns over his thigh.

“Emilia?” you guess. “Or what about… what was her name? Harper?”

Sebastian scoffs, his pulse pounding. “Not even a little."

You grin like you don’t believe him. “Not even for the—"

“Don’t.”

You huff a dramatic sigh. “Sebastian, it’s okay if you still think about them.”

“I don’t.”

That’s the truth.

Because he doesn’t think about Emilia. Or Harper. Or any of them. Not when every girl he’s ever been with has only been a placeholder for the one person he can’t fucking have.

You hum. "I miss some of mine."

Sebastian exhales sharply, jaw flexing.

Oh, for fuck’s sake.

He should not be listening to this, but you keep talking, your voice low, thoughtful, the alcohol making you too loose, too honest.

“I mean, not them, really,” you continue. “Just, like… the sex.”

Sebastian almost veers off the fucking road.

He physically has to adjust his grip on the wheel, blinking hard against the heat that flares in his gut, against the way his brain immediately starts supplying images he shouldn’t be thinking about.

You miss the sex. Not the relationship. Not the romance.

The sex.

“You literally have a boyfriend,” he grinds out, his voice tight.

He hears you exhale, feels you shift slightly in his lap. “So what?”

Sebastian finally glances down at you, just for a second, just to make sure he actually heard you right. Because you can’t be serious.

But you are.

You’re staring at him, lips parted, the distant glow of headlights and streetlamps casting golden light over your face.

Sebastian lets out a short, humorless laugh. “'So what'?” he repeats, shaking his head. “Jesus, you really are drunk.”

You make a small, amused noise, your fingers tapping idly against your thigh.

“I’m not that drunk,” you murmur.

Sebastian exhales sharply through his nose. “Yeah?” he mutters. “Could’ve fooled me.”

You scoff, rolling your eyes. “I just meant that some of my exes have been better in bed than him, that's all."

Sebastian hums noncommittally, keeping his eyes on the road, but his grip on the wheel is tight. Because what the fuck is he supposed to do with that information?

On one hand—good. He’d never liked your boyfriend anyway. The guy was mediocre at best, the kind of safe, boring choice you made when you were trying to convince yourself you wanted stability instead of passion. On the other—

Sebastian doesn’t exactly want to hear about how great some other guy’s dick was.

But the damage is already done. Because now, he’s thinking about it. Thinking about you with them, thinking about the ones who were better, wondering what made them better.

Was it how they touched you? How they talked to you? Was it the way they knew exactly how to pull you apart, how to ruin you? Was it—

The sensible thing to do is change the subject. Ignore it. Pretend you never said it and focus on not losing his goddamn mind while you’re still draped across him, still warm against his lap, still too close.

But then—because he’s a fucking idiot—the words slip out before he can stop them.

“Who was best?”

You stretch a little, completely oblivious to the way every tiny movement of yours is sending heat pooling in his gut.

“Well,” you muse, eyes glinting with something dangerous, “do you want, like, a ranked list? Or just an all-time favorite?”

Sebastian exhales sharply through his nose. “You know what? Forget I asked.”

“No, no,” you tease, scooting up slightly. “You asked. You wanna know.”

I really fucking don’t.

But he stays silent. Because some stupid, masochistic part of him actually does.

You pretend to think for a moment, eyes flicking to the windshield, lips curving in a way that’s going to fucking kill him.

“Probably Caleb,” you finally say, voice thoughtful, casual, like you’re discussing a meal you once had instead of someone who used to fuck you.

Sebastian hates how his stomach twists.

“Caleb,” he repeats, expression unreadable.

“Yeah.”

Sebastian shifts his grip on the wheel, fighting the urge to roll his shoulders, shake off the tension creeping up his spine.

He remembers Caleb.

Tall. Broad-shouldered. Stupid fit. A Muggle who played rugby at Uni. Arsehole.

He also remembers how pissed he was when you first started seeing him, how much he fucking hated the way Caleb used to pull you into his lap at parties like he owned you.

Sebastian clears his throat. “Huh.”

You grin, shifting again, your hand brushing against Sebastian's arm now. “He was good."

"Why?"

The question slips out before he can stop it and you smirk, and Sebastian knows—he knows—he’s about to regret asking.

“He was just…” you hum, tilting your head like you’re choosing your words carefully. “He was… I don’t know. Rough, I guess? He liked taking control. Giving orders. That kind of thing.”

Sebastian grips the wheel so hard it might snap in half.

Because now he’s picturing it. Picturing you, pressed down against a bed, hips pinned, whimpering, gasping, hands gripping sheets, your voice breathy as you—

Stop.

Sebastian's jaw locks, his pulse hammering at his throat. “I didn’t need that image, thanks."

You laugh softly. "Why not? I thought maybe you wanted to take notes."

He laughs, low and dry, shaking his head. “In your dreams.”

Your smirk widens. “Mm. Definitely in my dreams."

Sebastian nearly groans.

Because fuck you for saying that. For laughing softly, for dragging your fingers against his stomach as you shift again, like you can’t stop pressing yourself against him. For smirking when you say it, for the way your voice dips, lower, softer, like you’re confessing something, like you’re actually being honest.

Sebastian holds in a sigh. He is not playing this game.

Because you’re drunk, and you’re not thinking about what you’re saying, and in the morning, you won’t remember how you said it, how your voice curled around the words like you meant them, and because your fucking boyfriend is waiting for you to get home.

So he laughs, low, dry, dismissive.

“Sure,” he mutters. “That’s a nice little fantasy you got there.”

“You’re such a dick,” you say, still amused.

Sebastian hums, flicking the turn signal as he veers onto the quiet stretch of road leading out of town.

Eight more minutes.

Just eight more minutes and he can drop you off. He can shake off the feeling of your fingers grazing his stomach through his t-shirt and of your weight pressing against his lap like it’s the most normal fucking thing in the world.

Eight more minutes and this night will be over.

Then you speak again.

"...Have you ever thought about it?"

“Thought about what?”

You grin, and it’s slow, lazy, dangerous.

“Us,” you say simply.

Sebastian stiffens.

Has he thought about it?

Fuck, he’s spent years trying not to think about it.

Not to think about you pressed beneath him, his hands gripping your waist, his mouth dragging over your skin, your voice breathy in his ear. Not to think about the way you’d sound, the way you’d fall apart, the way you’d look wrecked and flushed and fucking perfect. Not to think about how you’d feel under his hands, under his mouth, how you’d—

Sebastian shoves the thought away violently.

Exhales.

He's not about to tell you that.

“No.”

You laugh softly. Sebastian’s jaw tenses. And then you sit up, just a little, your breath warm against his neck.

“I have,” you say.

Sebastian stops breathing, his pulse slamming against his ribs as he flicks his gaze toward you—just for a second, just long enough to see the way you’re looking at him.

You’re not laughing now. There’s no teasing smirk, no smugness either.

Sebastian swallows hard, forcing his eyes back to the road, trying to think, trying to process, trying to decide if this is real or just another one of your drunken, fleeting moments that won’t mean a damn thing in the morning.

Then your hands move, fingers dragging down his chest, slow, deliberate, your touch featherlight but undeniable.

Sebastian grits his teeth, forcing himself to focus, forcing himself to keep the car steady, forcing himself to—

Your fingertips graze the waistband of his jeans, hooking slightly under the hem, and that’s it.

Sebastian's hand shoots out, gripping your wrist, stopping you.

The car is silent. Just the hum of the engine. Just the sound of both of you breathing hard.

He exhales, slow, controlled. But when he speaks, his voice is wrecked.

“Don’t.”

A pause.

"Why not?"

"Because you don't mean it," he mutters, voice rough, like he’s forcing the words out through sheer willpower.

"...What if I do mean it?"

Sebastian slams on the brakes. The car jerks to a stop, tires skidding slightly on the empty country road, the sudden silence deafening.

He stares at you, his pulse hammering, his breath coming too short, too fast.

"Are you fucking with me?"

"Do I look like I’m fucking with you?"

Sebastian exhales hard through his nose.

Yes. No. Maybe. Fuck if he knows.

Because this is what you do.

You flirt. You tease. You get close, just close enough to ruin him, and then you pull away like it never meant anything at all. And right now, you’re still in his lap with your fingers still hooked in his jeans and your breath hot against his neck, and this... this is dangerous. If you’re joking, if this is just another round of you pushing boundaries you never actually mean to cross, it will break him.

Sebastian tightens his grip on your wrist just for a second—just long enough to make sure you’re listening, really fucking listening.

“This isn’t a joke,” he says, voice rough, uneven. “This isn’t a game, it's not—”

"Sebastian."

Suddenly, you don’t seem drunk at all.

The teasing lilt in your voice disappears, evaporating into the thick silence between you. There’s no lazy amusement, no coy smirk tugging at the corner of your lips, no playful glint in your eyes like there always is when you push him just to see how far he’ll let you go. It’s all gone.

Instead, you are sharp, your gaze cutting through the dim light of the car, slicing right into him.

Sebastian feels the shift like a physical thing, like the weight of something heavy pressing down on his chest. His grip tightens on the wheel out of instinct, like it’s the only thing keeping him grounded, but it does nothing to steady him.

Because suddenly, you are steady.

You pull back just slightly, just enough to give him an out, to give him space, but you don’t really go anywhere. You are still there, your body still warm on his, your breathing still uneven, just like his. You simply leave just enough distance between you for him to feel it, the unbearable stretch of space that’s always existed, the one he has spent years pretending doesn’t hurt.

For a moment, you just look at him.

Sebastian sees the hesitation in your expression, the flicker of uncertainty in the way your mouth parts slightly, like you’re on the verge of speaking but don’t quite know how. You look like you’re standing at the edge of something dangerous, like you’re deciding whether to step back or let yourself fall.

Then, you inhale. Slow, measured, determined. And you let it all out.

"I’ve always imagined it was you," you say, voice quiet but unwavering, like you've already made peace with the confession before it even leaves your lips. "Every single time I’ve had sex since I lost my virginity, I’ve imagined it was you."

Sebastian’s stomach plummets, and for a split second, he genuinely wonders if he’s actually dead. If he crashed the fucking car and this is what the afterlife feels like—sitting in the driver’s seat with his best friend sprawled across his lap, admitting the thing he has spent years torturing himself over.

You keep going.

"If hell is real, I’m fucking damned," you huff a laugh, your voice coming out rough, frayed at the edges, "because I’ve touched myself to you more than any reasonable amount."

Sebastian makes a wrecked sound in the back of his throat, one that he barely recognizes as his own. His hands clench into fists at his sides, fingers twitching like they don’t know what to do with themselves. Because what the fuck is he supposed to do with this With you?

You're rewriting everything, burning down every carefully constructed wall he has built to keep himself from wanting you too much.

And then you land the final fucking blow.

"You want the truth? I’ve been in love with you since we were fifteen," you whisper. "And I want nothing more than for you to take me home at least one fucking time."

Sebastian’s body locks up. His vision tilts. Everything inside him goes too tight, too hot, too overwhelming. His fingers are trembling. His pulse is out of control. His mouth is dry.

No, this isn't a game, or some some drunken, fleeting moment. This isn’t a joke.

This is real.

And he doesn’t know how to breathe.

You let out a short, humorless laugh, shaking your head. "And I get it if you don’t feel the same," you say, voice softer now, almost like you don’t want to say it, almost like the idea is too painful, "if that’s why you’re acting like this, then I get it."

You laugh again, except this time it’s self-deprecating and bitter. "I mean, for fuck’s sake," you mutter. "I’ve got a boyfriend anyway. This is so fucked up, I know. I just, I don’t know what happened. But something inside me snapped and I can’t hold back any longer."

Sebastian’s jaw tightens. Because yeah, this is so fucking fucked up. And yeah, you do have a boyfriend and he is literally waiting at home for you right now. But Sebastian doesn’t have it in him to care.

Because you love him.

For ten years, he’s wanted this. Ten fucking years of pretending, of ignoring, of pushing it down so deep it nearly killed him. Every drunken flirtation, every lingering touch, every fucking time you smiled at him with that look in your eyes that made him wonder if you wanted it too, and now he knows you did. Knows you do.

And you—

Fuck, you think he doesn’t feel the same?!

"Just forget I said anything," you mumble. "Seriously. I don’t know what I was thinking, I—"

Before you can talk yourself further into this spiral, Sebastian's hand shoots out, gripping your wrist.

You freeze.

He exhales sharply through his nose, his grip tight, his pulse racing, erratic, wild. Then, his voice low, rough, wrecked beyond repair—

"I've been in love with you since we were fifteen, too."

Your lips part, barely breathing, completely still, like you’re trying to process the weight of those words, like you’ve lived in a reality where that wasn’t true for so long that you don’t know how to exist in one where it is.

And then your face crumbles.

"Sebastian," you whisper, voice breaking, shattered.

And that’s it. That’s fucking it.

Sebastian crushes his mouth against yours.

It’s not slow. It’s not careful. It’s ten years of frustration, ten years of jealousy, of biting his tongue, of pretending he didn’t want you, and ten years of believing he could never have you—all of it, all at once, breaking loose, crashing down.

And you kiss him back.

Hard.

Desperate.

Your hands grip his shoulders, his jaw, fisting into his hair as you pull him closer, closer, like you need this just as badly as he does, like you’re starving for him.

Sebastian groans into your mouth, swallowing the sound of you gasping against his lips, swallowing everything he’s ever wanted from you.

His mouth moves to your jaw, trailing down your neck, sucking a dark, bruising mark against your pulse point just to hear you whimper.

"Tell me again," he growls against your skin, voice rough, demanding.

Your nails dig into his arms, your breath uneven, panting.

"Tell me again how you've thought about me," he mutters, dragging his lips up to your ear. "How you imagined it was me," he rasps, fingers slipping under the hem of your top, gripping your bare waist.

You let out a soft, broken whimper, your fingers curling into his hair and pulling. He grips your jaw, tilting your head so you have no choice but to look at him.

Your lips part, eyes glassy, dark, and fucking desperate. "I imagined you every time."

Sebastian throws the car into reverse.

Because he’s not taking you back to your pathetic excuse of a boyfriend. Not when you’ve spent the entire night driving him insane, not when you're touching him, teasing him, whispering in his ear about the exes you never actually wanted because they weren't him.

Not when you just told him you’ve loved him for a decade.

No, he’s taking you home, and the second he gets you there, he’s going to ruin you.

You blink at him, dazed, lips kiss-bitten and swollen, still straddling his lap.

“Where are we going?” you ask breathlessly.

Sebastian’s grip tightens on your waist as he turns the wheel.

“My place."

Your eyes darken, and then your hands are everywhere—fisting into his hair, sliding down his chest, curling under the hem of his t-shirt like you need to feel his skin and touch as much of him as possible.

You trail hot, open-mouthed kisses down his jaw, your breath warm, wrecked, and he groans, tipping his head back slightly as your teeth graze his throat.

“Fuck,” he mutters, barely able to focus on the road as your hands wander lower.

You shift in his lap, your thighs spreading over him, and Sebastian hisses, cursing under his breath as you press down against him, rolling your hips just slightly.

And then your hands move lower.

Your fingers trace the waistband of his jeans, toying with the button, flicking it open. His hips jerk up instinctively and your laugh is breathy, lips grazing against his jaw.

“You drive too well for someone getting felt up,” you murmur against his skin, your voice all smug amusement and heat and fucking destruction as you drag a hand over the bulge in his jeans.

Sebastian groans, a deep, wrecked sound in his throat, his hips jerking into your palm despite himself.

“Fuck, don’t—”

“Don’t what?”

Sebastian slams his fist against the steering wheel, jaw clenched, desperate to focus, desperate to not lose his mind completely.

"If you keep doing that," he growls, low, warning, "I'm gonna pull over and fuck you in this car."

Your breath catches. Sebastian watches as your pupils blow wide, lips parting slightly, grip on him tightening.

His cock twitches in his jeans.

Jesus fucking Christ.

The drive to his place is the longest fifteen minutes of his fucking life. By the time he pulls into his driveway, he’s barely holding himself together.

His jeans are too tight, his body is on fire, his pulse is a reckless, unforgiving thing pounding against his skin, and you—you are still in his lap, still pressed against him, still dragging your lips over his jaw, still palming over him, still teasing, still ruining him.

Sebastian barely gets the car into park before he’s gripping your hips, hauling you against him, mouthing at your throat like he’s starved for it.

You gasp, fingers tangled in his hair, pulling him closer, rocking your hips over his lap like you’re hellbent on making him suffer.

And he lets you. For ten long fucking seconds, he lets you.

Lets you grind down on him, lets you drag your nails over his scalp, lets you press hot, open-mouthed kisses against his jaw, lets you whisper his name against his lips, against his skin, against his fucking soul.

Then—

“Inside,” he mutters, voice rough, strained beyond repair.

You blink at him, dazed, breath uneven and wanting. And fuck, he’s never wanted anything more than this. More than you.

The second he pulls you out of the car, you laugh, breathless, fingers gripping his shirt, swaying slightly in his grasp.

Sebastian catches you easily, one arm sliding low over your waist, his palm pressing into the soft curve of your hip, and fuck, he loves the way you feel against him, like you were meant to be there.

You tilt your head back, looking at him through half-lidded, dark-lashed eyes, “You gonna fuck me out here?” you murmur, smirking as you lean up, breath warm against his throat.

Sebastian groans, his hands tightening on you. “Don’t tempt me.”

You giggle, bright and shameless, dragging your nails down his chest, lower, lower, until he’s grabbing your wrist and tugging you along.

The second the front door closes, Sebastian is on you.

His hands in your hair, his mouth crashing against yours, his hips pressing you against the door as he kisses you so hard it knocks the breath from your lungs.

And you moan into it, fisting your hands in his shirt, dragging him closer, biting at his lower lip.

Sebastian growls, pressing into you, his knee slipping between your thighs, forcing them apart.

You let out a whimper, grinding down against him, your fingers tugging at the hem of his t-shirt, pushing it up, trying to get it off.

Sebastian laughs, breathless, rough, dragging his lips down your jaw, sucking another mark onto your throat just to hear you gasp.

“You’re impatient, aren’t you?”

You huff, rolling your hips against his thigh, lips curled into something dark, something smug, something absolutely fucking ruinous.

“You’ve made me wait a decade, Sebastian.”

Sebastian’s grip tightens. and then he’s lifting you, hands firm under your thighs, carrying you through the house like he’s done this a hundred times before, like deep down he’s always known exactly where this was going to end.

You laugh again, thrilled, breathless, arms wrapped tight around his neck as he kicks open his bedroom door and drops you onto the bed.

Sebastian stands at the edge of it, looking down at you—panting, flushed, wild-eyed, ruined before he’s even touched you properly.

You smirk.

“You just gonna stand there, Sallow?”

Sebastian smiles, dark and dangerous. Then he’s crawling over you, one knee pressing between your thighs, his hands bracketing your face, his lips ghosting over yours, teasing, testing, torturing.

His voice is low, a promise, a warning.

“Not a fucking chance.”

He takes your mouth again, swallowing your breathy little gasps as he kisses you deep, slow at first, dragging his tongue against yours, learning the taste of you, the heat of you, memorizing this moment in case the world ends tomorrow and this is all he ever gets.

And you fucking moan.

Loud and wrecked and needy, and it does something to him, something devastating, something that makes him tilt his hips down, pressing into you properly, rolling against you in a way that makes you gasp against his lips.

“Fuck, Sebastian—”

His fingers work automatically, popping the button of your jeans, sliding the zipper down, tugging the fabric past your hips—revealing more, more, more.

Sebastian has seen you a thousand times—in every possible way, in every possible light.

Drunk off your ass at parties, laughing with your head thrown back, cheeks flushed, eyeliner smudged from the heat of the room. Half-asleep, curled up in the passenger seat of his car, your fingers twitching as you dream. Post-workout, sweaty and flushed, hair stuck to your forehead, chest rising and falling as you try to catch your breath. Dressed to the nines for some god-awful date with some guy who wasn’t him, your perfume lingering in his car long after he dropped you off.

And yet, he’s never seen you like this.

Laid out in his bed, your lips swollen, your chest rising and falling in quick, uneven breaths, your jeans halfway down your legs beneath his hands, the anticipation humming between you so thick it feels like drowning.

You’re reaching for your top, fingers curling around the hem, ready to peel it off—not that it ever hid much anyway.

Sebastian should help you. He should be the one ripping that top off, the one dragging it up and over your head with shaking fingers and an aching hunger that’s been simmering under his skin for years.

But he doesn’t. He just watches as you pull it up slowly, revealing more, more, more.

His mouth goes dry.

Sebastian can’t stop looking.

You are a masterpiece.

Soft and plush, all curves and warmth, the kind of body meant to be touched, gripped, worshiped. The gentle rise and fall of your breath makes your stomach shift beneath the dim bedroom light, and fuck, he wants to put his hands there, feel the way your skin gives under his palms, kiss every inch of it. Your thighs—thick, full, fucking perfect—press against his thigh, and he thinks about spreading them, about feeling them squeeze around his waist, about sinking his teeth into them just to hear the way you’d gasp. Your hips, generous, tempting, made for his hands, make his fingers dig into the sheets, because all he can think about is gripping them, holding you down, guiding you. Your breasts, full and heavy, barely contained by the sheer lace of your bra, stretch against the fabric, making his vision tilt, his pulse hammer, his restraint fucking snap.

And then there’s everything else—the parts of you that make his chest ache, make his stomach tighten, make him wonder how the fuck he’s supposed to survive this. The stretch marks that paint your skin in soft, pale ribbons, evidence of time, of change, of life of a body that has existed beside him for years, growing, shifting, becoming something that was always beautiful but now feels like it was made for him. The softness that wasn’t there when you were younger, but grew with you, grew beside him, shaped by late-night drive-thrus, three too many beers, appetizers you never hesitated to share with him, the comfort of knowing you never had to shrink yourself. The dimples, the dips, the folds where your skin creases when you move, the evidence of a life fully lived, of a body that has only ever been yours—until now. Until him.

And you—you’re wearing a matching set. Black lace. Thin straps. Delicate details that don’t really hide a damn thing.

"Look at you," Sebastian says breathlessly, fingers tracing along the edge of your underwear, teasing. "Dressed up all pretty. You knew, didn’t you?"

You hum, lazily smug, shifting your hips just slightly, just enough to make his brain fucking short-circuit.

"Maybe," you murmur, biting your lip. "Maybe I wanted to be prepared."

Sebastian’s breath stutters, something deep, something dangerous curling in his gut, something possessive and wrecking and unbearable, because fuck—

Prepared? Did you know you were confessing him tonight? Did you get dressed for this moment? Or is he just filling your boyfriend's shoes?

His stomach twists, the thought curdling in his chest, bitter and raw, but then—

Does it matter? Because you're his now.

Sebastian leans in, pressing his mouth to the soft swell of your stomach, dragging his lips along your skin, his fingers curling into your thighs, his breath hot, his hands desperate.

“God, you have no fucking idea how much I love your body, do you?"

You make a wrecked little sound, your hands tangling in his hair, pulling.

Sebastian grins against your skin, dark and dangerous, pressing his lips lower, biting, sucking, making sure he leaves marks, making sure you feel exactly how much he’s wanted this.

You shift beneath him, breathless, giggling as your fingers find the hem of his shirt.

"Only fair," you murmur, tugging at the fabric, your voice teasing, expectant.

Sebastian huffs out a breathless laugh, shaking his head, but he lets you drag it up, lets you peel it off him, lets you look.

Because of course you should get to look.

He just wasn’t expecting to care so fucking much.

Call him arrogant, but he’s always known he’s good-looking. It’s never been a secret.

The wrong women (everyone but you) have always flocked to him like moths to a flame, drawn to the sharpness of his jaw, the cut of his smirk, the way he carries himself with an easy confidence that makes it seem like he never second-guesses a damn thing.

But this? This is different.

Sebastian never had trouble maintaining a trim figure back at Hogwarts, never gave it much thought beyond Quidditch and dueling and running from the consequences of his own goddamn actions. But adulthood claimed him differently, and that Sallow metabolism slowed to a crawl.

Sebastian is not lean.

And normally? That doesn’t bother him. Normally? He doesn’t care.

But right now, under your hands, under your gaze, in his bed—he does.

Because you’ve always been the most stunning fucking person he’s ever known. Because you could have anyone, and you always did.

Rugby players. Duellists. Healers who spend their breaks lifting weights instead of eating lunch. The kind of men who look like they were chiseled out of stone, sculpted into something untouchable, untouchable except for you—because you’ve had them.

Those were your exes.

And now here Sebastian is, broader, heavier in places they weren’t, softer in places they weren’t. Because he’s never been the type to count macros or meal prep or wake up at the ass crack of dawn to run five miles before work.

He’s still strong, sure—Auror training keeps him fit. But he’s also a man who doesn’t think twice about splitting a second plate of chips with you at dinner, who always finishes your leftovers because “wasting food is a crime”, who drinks pints after work without a second thought, who fills out his shirts more than he used to, who carries weight in his chest, his stomach, his thighs.

And now, here he is—bare in front of you. And you’re staring.

Sebastian wants to say something. Wants to make a joke, wants to shift your focus, wants to ignore the way something unsteady coils in his gut when your gaze drags over him—

Then you breathe out, soft, awed, wrecked.

"Fuck."

Sebastian freezes.

Your hands reach out, palms flattening against his chest, sliding over his skin, tracing down his stomach, your fingers pressing into the flesh there—

"You’re so fucking hot, Sebastian," you murmur, breathless, desperate, like you’re telling him the most obvious thing in the world.

He swallows, something rough and wrecked and disbelieving curling in his chest. "Yeah?"

You hum, dragging your hands back up his chest, your fingers tracing the freckles there, the muscle, the places where he’s softer than he used to be, pressing your lips just below his collarbone.

"Always have been," you hum. "But it's been really fucking unbearable the last few years."

Sebastian laughs, breathless, disbelieving, staring down at you like you just told him the sky is green, like you just shattered some fundamental truth about the universe.

Because fuck off—you’re serious? The last few years?

Oh. Oh. you have a thing for him like this—not when he was lean, not when he was a wiry, arrogant little shit back at Hogwarts, but now. Now, when he’s bigger, broader, heavier.

Something dark, something deeply satisfied, something possessive coils in his chest.

“Oh,” he smirks, his voice low, rough with amusement, with understanding, with something sharp and teasing. “So this is what you’re into?”

You blink up at him, your hands still roaming his chest, and fuck, you look ruined.

Sebastian lets out another low, rough chuckle, dragging his fingers down your body, spreading his weight over you, pinning you to the bed. He grabs your wrists, pressing them above your head, trapping them against the pillows.

“You mean to tell me,” he murmurs, lips hovering just above yours, teasing, testing, “that while you were off fucking all those blokes—”

You inhale sharply, your lips parting, your body arching subtly under him.

“—those assholes with their six-pack abs, the dueling champions, professional fucking athletes—”

You whimper softly, and fuck, he feels it. Feels the way your body reacts to him—not to them, not to some long-lost ex, not to your boyfriend, but to him, to his voice, to his weight pressing you into the mattress.

His grin turns wicked.

“You were picturing this?” he teases, his grip tightening just enough to make you shiver. "Me? All soft and heavy and fucking desperate for you?"

Your breath stutters, your thighs twitching against his hips.

Sebastian chuckles, dragging his lips back up to your ear, smirking when he feels the shiver that runs through you.

"And here I was, thinking I let myself go," he mutters.

Your breath hitches, but before you can say anything, he’s pressing a hot, open-mouthed kiss to your throat, sucking a mark there, then another, and another, branding you, making sure you remember this, making sure you feel it.

Your wrists twitch in his grip, but he doesn’t let you move.

Sebastian fucking loves it. Loves the way you squirm, the way your lips part, the way your chest rises and falls in uneven little breaths, the way you’re looking up at him like you don’t even know how to handle what’s happening to you right now.

His smirk deepens. “Tell me, love,” he murmurs, dragging his lips down your jaw, his teeth grazing your throat, “if this is what you wanted all along, why the fuck did you waste all that time with them?"

Your lips part, your expression flickering between dazed, ruined, and incredulous. And then you scoff.

"Because you weren’t fucking me, Sallow."

Sebastian freezes for a beat. Then two.

Then he laughs—low, rough, something almost mean curling at the edges of it. "No," he murmurs, dragging his lips down your throat, grazing his teeth against your pulse. "I wasn’t. But I am now."

You shudder beneath him, your body arching against his in some helpless, desperate little movement that goes straight to his cock.

"Impatient, are we?" he murmurs, smirking against your skin.

You huff a breathless laugh, hips shifting beneath him, fingers flexing in his grip. "You’ve made me wait ten years. Figure it out."

"You're not the only one who waited, you know—"

Sebastian barely gets the words out before you tug your hands free, fingers reaching for his jeans, already undone from your teasing in the car. And he should be savoring this—should be dragging this out, making you beg for it, for him, for all of it—but you're already shoving his jeans past his hips, and he loses the ability to think entirely.

Then your hand slips beneath the waistband of his briefs, and Sebastian’s entire body tenses, his breath catching as your fingers curl around the length of him, teasing, testing.

“Christ,” he exhales, shuddering, his forehead dropping to yours.

Your eyes flick up to his, and the way you look at him—blown pupils, parted lips, your expression equal parts fascinated and utterly fucking desperate—it makes his cock twitch in your grasp.

He can’t fucking handle this.

His fingers tighten on your thighs, his jaw clenching, his entire body burning with the effort it’s taking not to lose himself completely.

Sebastian grabs your wrist, halting your movements, his grip firm but gentle.

Your brows lift slightly, breathless.

“Seb?”

His smirk is wicked, possessive, completely wrecked. He leans down, dragging his nose along the curve of your jaw, his lips brushing your ear.

"If we're going to do anything," Sebastian exhales sharply. "We might as well fuck. Otherwise, this'll be over before it even starts."

“Oh,” you breathe, dragging your nails lightly down his stomach.

"We've waited ten years for this," he murmurs, dragging his tongue along your skin, feeling the way you shudder. His voice drops lower, rougher, teasing. "So let's make it worth our while."

Your breath catches, your nails pressing into his skin as you tip your head back against the pillow, blinking up at him like you’re still trying to process this moment—this night, this reality where you’re here beneath him, breathless and wanting, where he’s finally allowed to touch you like this.

And then you grin, a little dazed, a little breathless, completely wrecked already, and say:

“Holy shit, we’re actually about to fuck.”

You both freeze, eyes locking, and then you both start laughing, some combination of nerves and disbelief and a decade of waiting for this exact moment finally crashing down at once.

“God,” Sebastian mutters, shaking his head as he presses his forehead against yours, still grinning, still feeling that wrecked, desperate thing curling low in his stomach. “That’s what you have to say right now?”

You giggle, your fingers smoothing over his shoulders, down his chest. “I mean—come on, this is so surreal.”

Sebastian scoffs, nipping at your jaw, pressing a rough, open-mouthed kiss to your throat, humming when you shiver beneath him.

“Oh, I’ll make it real, love, don’t worry.”

And then he’s moving again, hands everywhere, fingers slipping beneath the lace of your bra, under the waistband of your thong, tugging the fabric down your shoulders.

His breath hitches as your breasts spill free, full and heavy and perfect, your soft curves shifting beneath him, and he can’t stop staring. He feels greedy, like he needs both hands, both lips, every fucking inch of him touching every fucking inch of you.

His fingers brush over the swell of them, thumbing over one hardened nipple, and you let out a soft, breathy little sound that nearly kills him on the spot.

And then your eyes flick down, your breath catching, because he’s still in his briefs, but they’re pointless at this point, and you can see exactly how fucking gone he is for you already.

Your lips part, eyes widening slightly, voice soft, awed, wrecked—

“Oh, fuck.”

Sebastian snaps his gaze up to you, brows lifting.

“What?”

You swallow, blinking at his broad chest, his stomach, his cock aching against the fabric.

“Just trying to wrap my head around the fact that my best friend is secretly built like a fucking god,” you say, laughing breathlessly, teasing, and yet completely, unabashedly honest.

Sebastian laughs, shaking his head like he can’t believe you. “Oh, I’ll remember that,” he says, voice thick with amusement, with something darker curling at the edges. “Next time you decide to insult me, I’ll remind you that you said that.”

You grin, tilting your head back against the pillow, watching him through half-lidded eyes.

“I mean,” you hum, dragging your nails lightly down his chest, “the evidence is pretty overwhelming.”

Sebastian groans, dropping his forehead to your shoulder for a second. "And here I thought you preferred the blokes built like Roman statues." He hums, dragging his lips lower, pressing open, slow kisses over your collarbone, between the swell of your breasts. “Should’ve known better, huh?” he murmurs, teasing, grinning against your skin. "Turns out my best mate likes them thick."

You huff a laugh, but it breaks into a whimper when he finally closes his lips around one pert, sensitive nipple, sucking, dragging his tongue over it, groaning when your back arches beautifully into him.

"Apparently," You mutter breathlessly, "You do too."

“Fuck yeah, I do,” he mutters, smirking, tracing the soft curve of your hip, gripping, kneading. “I've always known that. You've been ruining my life with it for years."

You meet his eyes, and your mouth curves into something downright sinful. “Yeah? So why the hell didn’t you do something about it sooner?”

Sebastian barely gets a breath in before you’re pushing him back, shifting your weight, twisting your body beneath him until he’s the one sinking against the headboard, his back hitting the pillows.

He exhales sharply, blown, wrecked, barely processing how fast you move—or the fact that you just fucking flipped him like that.

"Bossy little thing," he mutters, grinning, but his voice is hoarse, completely fucking ruined.

You straddle his thighs, pressing your hands into his chest, pinning him down like you’re making sure he doesn’t move.

And fuck. Sebastian just lets you. Lets you crawl over him, lets you drag your lips down his chest, his stomach, kissing and teasing and taking your fucking time.

He groans, his head tipping back, his hands twitching at his sides because he wants to touch you, wants to grip your hips, drag you back over him, but he doesn’t want to stop you, doesn’t want to break whatever the fuck this is.

His breath stutters when you press a slow, deliberate kiss over the curve of his hip, your fingers hooking into the waistband of his briefs, tugging, teasing.

Sebastian curses under his breath, his jaw clenched tight, his entire body drawn so tight with tension he thinks he might actually fucking die.

"Jesus," he mutters, his hands flexing at his sides.

You hum against his skin, dragging your nails over his stomach, over his thighs, soaking in the way his muscles twitch beneath you.

And then you drag his briefs down, past his hips, past his thighs, down enough to free him.

Sebastian groans, eyes slamming shut, jaw clenching as the cool air hits him, as he feels the weight of himself resting heavy against his stomach, already aching, already dripping for you.

And you just fucking stare, mouth parting slightly, eyes dragging down the length of him, slow, heavy-lidded, like you’re trying to process what you’re looking at.

Sebastian cracks one eye open, breath ragged, and he can’t help but smirk. His voice comes out low, rough, teasing—

“What is it?" He grins, tilting his head, watching the way your gaze flicks over him, the way you press your thighs together.

You exhale sharply, blinking like you need a second to find words.

“Oh, fuck.”

Sebastian laughs, full and deep, completely and utterly smug.

"Shit," you mutter, shaking your head slightly, still staring, like you're recalibrating your entire fucking world.

Sebastian grins, dragging a lazy hand down his stomach, wrapping his fingers loosely around himself, stroking once, slow, teasing.

"See something you like, sweetheart?" he murmurs, voice thick with wolfish amusement.

You snap your gaze up to his, glaring. "Fuck off." But your voice is breathless, wanting, wrecked.

Sebastian chuckles, tilting his head back, completely in love with the fact that you are absolutely, completely undone over him.

Then— then you lick your lips, and Sebastian stops fucking breathing.

You lean down, hands gripping his thighs as your tongue flicks over the head of his cock, licking up the sticky precum already there, your lips barely grazing the sensitive tip.

“Fuck,” Sebastian groans, his hands flying to your hair, fingers tightening, but you’re not done yet.

You swirl your tongue over him again, slow, deliberate, your nails dragging over his skin, and then—then you start mouthing off.

Because of course you do.

"You could have had me ten years ago, Sebastian," you murmur, voice low, teasing, sinful, your breath hot against his skin.

Sebastian grits his teeth, jaw clenching. "Yeah?"

"Yeah," you hum, pressing one last, teasing kiss to the sensitive tip before dragging your gaze up to his face, smirking. "How the fuck could you be so blind to the fact I've been in love with you this whole time?"

Sebastian groans, fingers tugging at your hair, his body trembling with restraint.

"You’re talking a lot of shit for someone who’s got my cock in their mouth," he growls.

You laugh, fucking laugh, your tongue flicking over him again. "You really can’t take a little criticism, can you?"

Sebastian snaps.

"Alright," he mutters, voice low, rough, wrecked. "That’s enough."

Before you can get another word out, his hands are on you, gripping your hips, flipping you back beneath him.

You gasp, laughing breathlessly, but it’s cut off when he pins you down, his full weight pressing you into the mattress, his hand wrapping around your throat, just enough pressure to make your breath hitch. Then—just to make sure you never forget who you belong to—

He spreads your legs, dragging his fingers down your stomach, between your thighs, feeling the heat of you, the slick, messy proof of how long you’ve needed this.

"Christ," he mutters, running his fingers through the wetness, spreading it over you, teasing you.

Your hips jerk into his touch, desperate, wanting, already completely undone. Sebastian grins, dark and satisfied, watching you unravel beneath him.

"Messy thing," he murmurs, pressing his forehead against yours as he drags his fingers up to himself, coating his cock in your wetness.

You practically purr beneath him, your thighs trembling against his hips, the heat of you slick and fucking ready for him.

This is it. Finally.

His fingers curl into the sheets beside your head, his cock dragging through the wet mess between your thighs, teasing, aligning, his vision tunneling, his entire existence narrowing down to the feeling of you, of finally having you—

And then your hand comes up. Soft. Trembling. Pressing against his cheek.

His gaze flickers down to yours. Sebastian stalls instantly. His brain short-circuits, muscles locking tight, because he knows that look.

He knows it in his bones.

Knows it in the way your fingers tremble against his cheek, in the way your lips part like you’re about to say something but don’t know how.

Shit. Wait. Are you having second thoughts? Are you saying no?

Sebastian’s stomach drops, panic flaring as he searches your expression, trying to push past the fog of lust, of need, of desperation—

But it’s not hesitation he finds. It’s something soft, something raw and pleading, and he feels it deep in his chest, where everything soft and aching for you lives.

“Sebastian,” you whisper, barely a breath, and fuck, his chest aches.

“What is it?” His voice is rough, hoarse, aching with restraint.

“If... if this is just for tonight,” you whisper, your voice small, fragile, like you’re saying it through the lump in your throat, “If this is just—if we’re just gonna wake up tomorrow and pretend it never happened, then I—” you pause, your voice breaking slightly. "I need you to tell me now."

And that—

That fucking shatters him. How can you not see it? The way he worships you, the way he’s been yours since he was fifteen fucking years old?

He exhales sharply, his grip tightening on your hip. “Are you out of your fucking mind?” he tips your chin up, forcing you to see him, forcing you to understand. “You think I could have you like this and then just go back to how things were?”

Sebastian shakes his head, dragging his thumb over your cheek, over your lips, his brows pulling together.

“I’m not built like that, love.”

Your throat bobs, your breath shaky, uneven, your body still trembling beneath him.

He swallows, something breaking open inside his chest. “I’ve wanted you for nearly half my life,” he murmurs, pressing his lips against your temple, against your jaw, against the curve of your throat. “You really think I’d just let you go after this?”

A breathless, almost helpless noise escapes you, your fingers curling into his hair, gripping, holding on to him like you don’t know what else to do with yourself.

Sebastian groans, pressing more of his weight down into you, anchoring you, grounding you, making sure you fucking feel him.

"You’re mine," he breathes against your lips, possessive, reverent, certain in a way that leaves no room for doubt. "You're fucking mine, and I’m yours, and I don’t care how fucking long it took us to get here—I’m not fucking going anywhere. You understand?"

Your lips part, eyes flickering between his, something desperate and so fucking relieved blooming across your face.

"Thank fuck."

Then you pull him down to you, crashing your mouth against his, kissing him like he just fucking saved you. It's messy, all tongue and teeth and years of wanting, and his hands move without thinking—gripping, claiming, spreading you open for him

You whimper into his mouth when he grinds against you, his cock dragging through the wet mess between your thighs, slick and aching and so fucking ready for him.

You shift beneath him, thighs trembling, reaching down between your bodies, lining him up yourself, guiding him right where you need him.

Sebastian chokes on a breath, his head dropping to your shoulder, his fingers digging into your hips.

"Shit," he groans, voice breaking.

He can feel you, feel the heat of you, the wetness of you, and his brain blanks.

He’s done for.

Because this isn’t just sex.

This is everything.

This is forever.

The Things We Do for Family | Sebastian Sallow x Reader

Words: ~5,200

Tags: Reader Insert, Female MC, No Y/N, No Hogwarts House, Humor, Protective MC

There are things that Hogwarts students simply know—unchallenged truths, whispered warnings passed down from year to year.

The Forbidden Forest is dangerous. Peeves is a menace. The best snacks at Honeydukes sell out by Saturday afternoon. Don’t trust the staircases to take you where you actually want to go. Never accept Garreth Weasley’s offer to ‘test something out’.

And, under no circumstances, should anyone fuck with your friends.

It isn’t official, of course. There’s no school decree, no printed rule in the Hogwarts handbook, it's not carved into the walls. It’s just… understood.

It’s not like you’re some fearsome monster or anything.

You’re a model student, by all accounts. Brilliant. Sharp. Precise. A skilled duelist, a quick thinker, someone who turns in their assignments on time, answers when called on, and doesn’t cause disruptions in class.

You don’t start fights. You don’t pick pointless arguments. You don’t openly break the rules—not in ways that can be proven.

You play the part well.

Because that’s what you had to do.

You grew up alone. No parents. No siblings. No one to step in when things got hard, no one to defend you when the world was cruel. When you were small, scared, and helpless.

So you learned.

You learned that no one was coming to save you. You learned that fairness was a lie, that justice only existed when you carved it out with your own hands. You learned that people could be awful for no reason other than that they could get away with it.

But now? Now, you have a family. Not by blood, but by choice.

And when someone speaks against them? Bad things happen.

The Ominis Incident

It started, as most things did, with a careless remark.

A fifth-year Ravenclaw—smart but not particularly bright—thought it would be amusing to make a joke at Ominis Gaunt’s expense. A cruel one. Something about how the Gaunts were all inbred lunatics, how it was only a matter of time before Ominis ended up just like the rest of his family.

The words reached your ears in the library, drifting from a table not far from where you sat.

"You know I hear they torture Muggles for fun—it’s practically a family tradition. Gaunts don’t have hobbies, just a long history of inbreeding and Crucio."

Laughter followed, a few snickers from their table, hushed but not nearly enough. Not nearly enough to keep you from hearing.

Your quill stilled mid-word, ink pooling in place. Across from you, Ominis sat straight-backed, his expression unreadable, but you saw the way his fingers tightened around the book he was holding, knuckles whitening from the force of it.

He wouldn’t say anything.

Ominis had spent years perfecting the art of indifference. Of carefully controlled expressions, of blank politeness that masked far too much. He never reacted to comments like these.

But just because he wouldn’t didn’t mean you wouldn’t.

You exhaled slowly, carefully. Then, without a sound, you closed your book and stood.

Not a word. Not a glare in their direction. Just a smooth, effortless departure, as if you had suddenly decided the library was boring and somewhere else required your attention.

The Ravenclaws barely noticed.

But they would. They absolutely would. Because Potions class was a very dangerous place. Especially for people who talked too much.

The next day, you walked to Potions without a care in the world.

Sebastian and Ominis flanked you, deep in conversation about some essay Sharp had assigned, with Sebastian whining dramatically about how unfairly long it was, while Ominis countered that perhaps he should have started it earlier than the night before it was due.

You weren’t really listening, because you already knew what was coming.

And sure enough—just as you reached the dungeon corridor—

BOOM.

The floor trembled slightly beneath your feet. A deep, echoing explosion, the unmistakable sound of a cauldron detonating mid-brew, followed almost immediately by the frantic shouting of students.

Gasps. Choking coughs. Someone let out a screech of absolute horror.

Sebastian and Ominis startled.

Sebastian’s head snapped up, eyes wide as he looked toward the dungeon doors. “What the hell—”

Ominis twitched beside you, tilting his head, as if straining to listen.

You? Didn’t even blink. You just kept walking, calmly, like nothing was amiss, like you hadn’t been expecting it for the last twenty-four hours.

Sebastian noticed. His gaze sharpened, flicking to you with a knowing squint. “That was—”

He hesitated. Then narrowed his eyes further.

“Okay,” he said slowly, “I know that face.”

You raised a brow. “What face?”

“That’s your I-did-something-but-you’ll-never-prove-it face.”

You tilted your head, feigning confusion. “I have no idea what you’re talking about.”

Sebastian scoffed and Ominis rolled his eyes, deadpan. “Uh-huh.”

Then the dungeon doors burst open.

A thick cloud of green smoke billowed out, sending students stumbling and coughing into the corridor. And in the center of it all, a group of very, very green Ravenclaws.

They clawed at their own skin, staring down at their hands in absolute horror. Their faces were the exact shade of an overripe toadstool, splotchy and uneven, and every time they opened their mouths, their tongues flopped out two inches too long.

Hysteria ensued.

Students gasped, some shrieked, others tried not to laugh. Professor Sharp stormed out after them, looking beyond exhausted, already massaging his temples.

“I told you,” he said, pinching the bridge of his nose, “not to add the peppermint extract.”

“WE DIDN’T!” One Ravenclaw wailed, voice garbled from their too-long tongue. “I—I don’t know what happened! We did everything right!”

Sharp did not look convinced.

Sebastian looked at you, long and slow, a glint of admiration dawning in his eyes.

“Did you—”

“I did nothing.” You walked past him, as if the entire debacle were none of your concern. “I was with you all day, wasn’t I?”

Sebastian’s lips twitched. “Yeah, but—”

“No proof, no crime.” You gave him a cheerful smile before stepping into the classroom.

Sebastian grinned. “Oh, I love you.”

It was offhanded, thoughtless, a casual jest, but it sent a sharp, pleasant warmth down your spine.

You didn’t react, though. Just smirked, settling into your seat. Because the message had been sent.

And Ominis Gaunt would never hear a word against his name again.

The Anne Incident

Rumors at Hogwarts were a force of nature.

They swirled through the halls, slipping between whispered conversations and behind cupped hands, growing more twisted with each retelling.

Some were harmless—who was dating who, which professor had it out for which student, the occasional Did you hear Peeves stole all the ink from the Ravenclaws again? But some? Some were cruel.

And this one... this one was about Anne Sallow.

It started at breakfast, when you overheard a group of Slytherin sixth-years in the Great Hall. You weren’t eavesdropping—not intentionally—but you had a habit of noticing things, of hearing too much when you weren’t meant to.

"Did you hear about Sallow’s sister?"

"Yeah, I heard she went mad."

"Lost it completely. The curse must’ve rotted her brain."

"That’s why she left, isn’t it?"

"Yeah, I heard she tried to hex someone in her sleep—"

Your fork warped in your grasp. A slow, controlled bend beneath your fingers, the metal bending in your grip.

Across from you, Sebastian had gone still.

He didn’t turn. Didn’t react. Didn’t give them the satisfaction.

But you saw the way his jaw clenched. The way his hand curled into a fist against the table. The way his entire body had gone taut, locked in place by sheer force of will.

He wouldn’t do anything.

Not because he didn’t want to. Not because he wasn’t capable of it—because he was.

Sebastian Sallow could be ruthless. You knew that better than anyone. You’d seen it firsthand, the sharp edges of his temper, the way his rage burned hot and all-consuming, leaving nothing but wreckage in its wake. You’d seen what happened when he felt cornered, when he thought he was out of options.

But he wasn’t that boy anymore. Because you and Ominis had dragged him back from the brink. Because you had looked him in the eye, years ago, when the dust had settled and the worst of it was over, and told him:

"You still have a future. Don’t throw it away."

Against all odds, he had listened. And now, this was his last year at Hogwarts and he was going to be an Auror. He was going to start over. Prove that he wasn’t just some reckless, violent delinquent one step away from Azkaban.

So no—he wouldn’t react. He wouldn’t take the bait. Wouldn't defend Anne, no matter how badly he wanted to. Wouldn’t let himself be dragged down into the same pit he’d barely crawled out of.

Sebastian was playing the long game.

But you? You weren’t.

Your revenge on Anne's behalf started small. Almost imperceptible.

The first Slytherin—the one who had started the conversation in the first place—was walking to class when it happened.

A single misstep.

His foot caught on something—thin air, perhaps—and he staggered forward, arms flailing in a desperate attempt to right himself. It didn’t work. His books went flying, parchment scattered across the stone corridor, and a bottle of ink tumbled from his bag, shattering upon impact and staining his robes in an ugly, irreversible mess of black.

A small accident. An unfortunate case of bad luck.

No one thought anything of it—until the second one fell.

In the exact same spot.

And then the third. And the fourth.

By the time lunch rolled around, all four of them had tripped at least half a dozen times each.

It wasn’t just limited to the corridor, either. They stumbled on staircases, barely catching themselves before they could go tumbling down. They walked straight into walls as if the castle itself had turned against them. One even managed to trip over absolutely nothing in the middle of the Great Hall and landed face-first into his own soup.

The snickers started soon after. The sideways glances. The poorly hidden laughter from classmates who found their sudden clumsiness far too entertaining.

It wasn’t enough to be suspicious.

Not yet.

Not until the moving staircase.

The ringleader of the group had spent too much time lingering in the courtyard after lunch, chatting up a group of girls who barely tolerated his presence. He realized too late that he was running behind and bolted toward Charms, racing up the moving staircases with zero grace and even less caution.

And then his foot caught.

There was nothing there. No loose stone or shift in the staircase, nothing at all to explain why he suddenly lost his footing.

But he did.

He stumbled backward, arms flailing wildly, fingers grasping at empty air as the momentum carried him too far—

And he plummeted.

Three flights.

A blur of robes and limbs, a crash of bone against stone, and then a sickening thud as he landed in a groaning, crumpled heap at the bottom.

A hush fell over the corridor.

Then—

Shrieking.

His friends rushed down to him, voices panicked, eyes wide with horrified realization as they took in his bruised, trembling form.

A girl ran to fetch Madam Blainey.

By the time she arrived, he was whimpering, clutching his arm like it might’ve snapped.

Hospital Wing. Immediate bed rest.

No one could explain what happened. No professor could find a cause. Some students claimed the stairs had shifted unexpectedly. Others swore that they saw nothing—no trick step, no loose stones, just an unseen force pulling him down.

It didn’t matter.

The moment he was carried off, you finally allowed yourself to smile.

Not a smirk. Not a grin. Just the smallest, most satisfied twitch of your lips.

Sebastian caught it. Because of course he did. He had been standing beside you the whole time. Silent. Still. Watching from the moment that asshole Slytherin stumbled earlier that morning to the moment he was carted off for medical attention.

And now? Now, he just exhaled, long and slow, shaking his head as his mouth curved into something unreadable.

“You’re dangerous,” he murmured, voice low.

You hummed, tilting your head in faux curiosity. “Am I?”

Sebastian turned fully then, facing you. His gaze searched your face, for guilt perhaps. For remorse. For something that might suggest you hadn’t meant for it to happen.

But there was nothing.

No trace of hesitation. No flicker of shame.

You were calm, collected, an completely unapologetic. Because nobody talked about Anne Sallow like that without consequence.

Sebastian blinked. Then, to your absolute delight, he grinned. Wide. Slow. A sharp, wicked thing.

“Yeah. You're very dangerous” he said, almost in awe.

Your stomach twisted. You ignored it. Instead, you just shrugged, voice as casual as ever.

“I don’t know what you’re talking about.”

Sebastian’s grin deepened.

The Poppy Incident

Poppy Sweeting was one of the best people you knew.

Kind-hearted, patient, and too good for the world, really. She spent more time in the company of magical creatures than she did with most people, and honestly? You couldn't blame her.

Because people could be cruel.

You first heard it one afternoon in the courtyard. A group of girls whispering amongst themselves, giggling behind their hands. You hadn’t been paying much attention—until you heard her name.

"Honestly, she’s weird."

"I know, right? It’s like she’d rather date a bloody Hippogriff than an actual person."

"Wouldn’t be surprised if she actually has."

Laughter, sharp and mocking. Like Poppy Sweeting was a joke. Like she was less than because she chose kindness over cruelty, creatures over people who didn’t deserve her time in the first place.

You turned your head and watched as one girl—a Hufflepuff, ironically—rolled her eyes, shaking her head in exaggerated exasperation.

"Beast-lover," she muttered, nose wrinkled like the word itself was distasteful. "It's unnatural, really. No wonder she doesn't have any friends outside of her precious Mooncalves."

Something cold and sharp settled in your chest.

You had no doubt Poppy had heard it. She was standing just a few paces away near the fountain, hands clenched tight at her sides.

She didn’t react. Didn’t turn. Didn’t say anything. She just exhaled, slow and quiet, like she was forcing herself to let it go.

You wouldn’t.

The next morning, that very same Hufflepuff woke up covered in fur.

Not all over, just her face.

A thick, fluffy coat of golden-brown fuzz, soft as a Puffskein, sprouting in wild patches across her forehead, cheeks, and chin.

According to Poppy, the screams started immediately, and the entire girls dormitory had woken up to it.

The girl, who turned out to be a fifth-year, had flown into a hysterical panic, shrieking as she bolted for a mirror, hands frantically scrubbing at her face like she could rub the fur away.

She couldn’t.

It was a very specific hex. One that lasted exactly one week.

Professor Ronen was baffled.

Madam Blainey was thoroughly fascinated.

And Professor Howin, bless her, had cooed over her like she was the most adorable thing she’d ever seen. You had a front row seat to the entire thing during Beasts class.

“This is truly fascinating,” she’d said, holding the girl’s chin and turning her face slightly toward the light. “I don’t believe I’ve ever seen transfiguration manifest quite like this! And so soft—feels just like a Kneazle’s coat, doesn’t it?”

The best part? It wasn’t harmful. It wasn’t painful. Just… humiliating.

You considered it a job well done.

When Howin had dismissed you for lunch, Poppy pulled you aside. She didn't say anything at first. Just stared.

You blinked at her, tilting your head. “Everything alright?”

Poppy squinted. Narrowed her eyes slightly. Huffed.

"You did that, didn’t you?"

You blinked again.

Because Poppy—sweet, gentle, pacifist Poppy—did not accuse people of things. Which meant she was completely certain.

You just smiled, giving her your most innocent expression. “I have no idea what you mean.”

Poppy just sighed, shaking her head. But then—just for a moment—she smiled.

Small. Subtle. Grateful.

Like she knew exactly what you’d done. Like she knew there was no use arguing, no point in telling you not to go to such lengths for her.

And then, without a word, she reached out and squeezed your hand.

The Natsai Incident

You had never liked Callum Thorne.

Seventh-year. Gryffindor. Arrogant. Loud-mouthed. The kind of person who had never been told no in his life and walked through Hogwarts like the world owed him something.

You’d tolerated him for years, mostly because you hadn’t needed to interact with him much. But this? This was different.

You were starting the day with Defense Against the Dark Arts. Professor Hecat had yet to arrive, leaving the class unsupervised and giving Thorne the perfect opportunity to make a scene.

Natty was speaking with Poppy near the front of the room, voice calm as she explained something about the Ministry’s policies on magical creatures in Africa compared to Britain. She wasn’t being loud, wasn’t even arguing, just explaining.

That’s when Thorne scoffed.

“Merlin’s sake, Onai, give it a rest,” he sneered from the back of the room, tossing his quill onto his desk with an exaggerated huff. “Do you ever get tired of standing on that bloody soapbox of yours?”

The room went still.

Natty turned, slow and deliberate, her expression unreadable, regarding him with that same poised, unshaken calm that made her such a force to be reckoned with.

“I was simply having a discussion,” she said smoothly. “No one is forcing you to listen, Thorne.”

“Right,” he drawled. “Except you never shut up about it. Always talking about ‘justice’ and ‘change’ like you think you’re going to fix the whole bloody world.” He smirked. “News flash, Onai—no one cares.”

A few of his friends chuckled.

Your fingernails dug into your palm.

Natty didn’t react—not outwardly, anyway. She just exhaled, slow and measured, and turned back to Poppy like his words had been nothing more than an inconvenience.

You? You were already plotting his downfall, and luckily, Callum Thorne was a creature of habit.

He always stayed out after curfew to flirt with whatever unfortunate girl he had chosen that week, and he always went up to the Astronomy Tower afterwards with his friends to play cards and drink whatever contraband alcohol they’d smuggled into the castle.

Which made him the perfect target.

That night, as the seventh-year tidied up the cards, stretching and yawning, likely already thinking about his warm bed waiting for him—

His legs froze in place. Not a Full Body-Bind. No, this was different.

A soft, subtle hex. A slow, creeping sensation, his feet adhering to the stone beneath him, then his calves, then his thighs.

By the time he realized something was wrong, it was too late.

He tried to step forward—failed. Tried to yank himself free—failed.

And then—with agonizing slowness—his entire body began to lift off the ground. No warning. No control.

He drifted upward, weightless, helpless, arms flailing as the stone ceiling came closer and closer—

And then, with a soft thump, he was stuck. Face-down, body pressed flat against the Astronomy Tower ceiling.

His screaming started immediately.

Loud. Panicked. A complete meltdown.

His friends, who had started their walk down the tower came bolting back up the stairs at the sound of his shouting.

“What the—?” one of them started, eyes wide as they gawked at the ceiling.

“Thorne?” another asked, dumbfounded.

You bit the inside of your cheek, holding back laughter as you hid beneath your disillusionment charm.

“GET ME DOWN!” Thorne bellowed, arms and legs flailing uselessly against the stone. “WHAT THE BLOODY HELL IS THIS?”

His friends stared, uselessly waving their wands, muttering counterspells that only resulted in Thorne spinning in slow circles, howling in distress.

When they realized they were utterly helpless, panic completely set in.

“What do we do?” one of them asked, looking between the others with wild eyes. “Should we get a professor?”

Thorne snarled. “NO! DO NOT—”

But it was too late. Because at that very moment, the Astronomy Tower door swung open once again, and a very tired, very unimpressed Professor Shah stepped inside.

There was a long, painful beat of silence.

Shah took in the scene.

The stack of contraband firewhiskey bottles on the table. The panicked seventh-years, wands still drawn, looking entirely too guilty. And Callum Thorne, still face-down, circling against the ceiling, hissing every curse word known to wizardkind.

She sighed, long and slow, as if she had simply had enough of this entire generation of students. Then, with an effortless flick of her wand, she cast a single spell.

And gravity returned. All at once. Thorne plummeted like a sack of bricks.

The landing was spectacular. A glorious, sprawling heap, limbs tangled, robes askew, one shoe missing entirely. His friends didn’t even try to catch him.

For a moment, there was only silence. Then—

“Hospital Wing,” Shah said simply, rubbing her temples. “Now.”

Thorne was half-carried, half-dragged down the tower steps, groaning the entire way.

And you?

You slept soundly that night.

By morning, half the school had heard the story.

"Did you hear about Thorne? Got stuck to the Astronomy Tower ceiling last night."

"He was crying by the time they got him down."

"Serves him right—bloke’s a complete asshole."

And you? You sat perfectly composed at breakfast, casually stirring your tea, listening as his friends panicked about who could have done it.

Sebastian, of course, knew.

He sat beside you, arms folded, lips pressed together, shaking with the effort not to laugh.

Finally, he exhaled, tilting his head toward you.

“You are actually unhinged,” he murmured, utterly delighted.

You simply sipped your tea. “I have no idea what you mean.”

Across the hall, Natty smiled.

Soft. Knowing.

The Sebastian Incident

You had been careful.

For years, you had woven your revenge into the shadows, never once leaving a trace of your involvement in the strange misfortunes that befell those who dared to insult your friends. You were precise, patient, undetectable.

But everyone has a breaking point. And yours? Yours was Sebastian Sallow.

It happened in the Great Hall when Scorpius Malfoy decided to idiotically open his big fucking mouth.

You hadn’t been paying attention to him at first. Why would you? People like Malfoy had never mattered to you. He was just another spoiled pureblood, another self-important waste of a surname who thought his words carried weight simply because he could afford to say them.

But then his voice cut through the din, and he said Sebastian’s name.

"No family name worth a damn, no money, no influence. Honestly, I don’t even know why the professors still put up with Sallow. And he’s an orphan, isn’t he?"

One of his friends nodded, grinning like this was some kind of joke. Like Sebastian Sallow’s entire life was nothing more than a punchline.

Malfoy snorted. "So he's got dead parents, a dead uncle, and a crippled sister who’ll probably never set foot in the wizarding world again. Wouldn’t be surprised if he ends up rotting in the same gutter he came from."

The words landed like a curse.

Sebastian had been mid-conversation with you, fork in hand, a faint smirk tugging at the corner of his mouth as he teased you about something inconsequential—some throwaway joke that would have normally earned him an eye roll and a shove.

But now? Now, he wasn’t moving. Not speaking. Not breathing. Just silent.

Rigid.

Like the weight of those words had turned him into stone.

And something inside you snapped.

It was almost funny, in retrospect, how much effort you had spent perfecting the art of subtlety.

Every step you had taken over the years had been measured, every spell carefully woven into the fabric of coincidence, every act of vengeance so meticulously placed that no one had ever been able to definitively trace it back to you. You had built a flawless reputation, balancing on the razor’s edge between brilliance and menace, justice and mystery.

But now? Now, as you rose from your seat, you weren’t careful at all.

You didn’t move like a shadow, didn’t cloak yourself in misdirection or the comfort of silence. No. This time, you wanted them to see you.

And the moment you stood, the Great Hall stilled.

Students stopped eating, stopped talking, stopped moving altogether. The clatter of plates and goblets faded into a thick, suffocating silence, as if even the walls of Hogwarts itself were holding their breath.

Your voice came out low. Cold.

"Say that one more time, Malfoy."

Scorpius turned lazily, like he hadn’t a care in the world. Like he hadn’t just spat on Sebastian’s entire existence for no other reason than because he could.

And he smirked. Merlin, he smirked. Like you were some insignificant thing, an insect buzzing too close to his ear.

“Oh?” he drawled, tilting his head. “Touched a nerve, have I? Which part got to you, I wonder? The fact that Sallow’s got no family? Or the part where I pointed out that he’s got no future either?”

You took a step forward. You could hear Ominis hissing at you to stop, to think about what you were doing before you got yourself deep into shit, gut you couldn't. Not when it came to your friends.

Not when it came to Sebastian.

Especially when he still hadn't moved. Hadn’t reacted. Hadn’t so much as breathed.

Your hand tightened around your wand, the weight of it comforting, grounding, an extension of the fury curling in your chest.

"You should tread carefully, Scorpius," you murmured, your voice smooth, edged with something lethal. "I know you think you're clever—that you can say whatever you like without consequence, just because you were born into the right family."

Your head tilted slightly, gaze sharp, cutting straight through him.

"But you should know something about me by now."

Malfoy’s smirk faltered just slightly. And then, before he could open his mouth again—

You flicked your wand.

Hard. Fast.

Malfoy's goblet exploded.

A concussive blast of magic sent shards flying, the remnants of his beverage splattering across his pristine uniform like spilled blood. A jagged edge of glass sliced across his hand, thin but deep, and he flinched, eyes snapping down to it with genuine shock.

"If you're going to run your mouth about my friends," you said coolly, watching him clutch his bleeding hand, "then you should be prepared to suffer for it."

Your next spell came before he could react. Before anyone could stop you.

A sharp twist of your wrist, and his mouth was gone.

Not silenced. Not muffled. Just… gone. Smooth, unbroken skin where lips should be, like his voice had simply been erased from existence.

The realization hit him immediately.

His hands shot to his face, clawing at his skin, a muffled scream—horrified, panicked—rising in his throat. He lurched backward, knocking into one of his friends, fingers digging at face like he could carve his lips back into place.

But you weren’t done. Not yet.

You needed something that would etch itself into the bones of this castle, into the minds of every single person watching in stunned silence. Something that told the whole goddamn school that if they so much as breathed wrong about Sebastian again, you would ruin them.

A simple hex would be too merciful. A standard jinx—something temporary, something easily countered—wouldn’t send the right message.

No, you needed something else. Something only you could undo.

Your wand rose, fingers tightening around the handle.

A familiar thrumming sensation curled through your bones, crackling at your fingertips, humming beneath your skin like a storm about to break. Ancient magic—the power that had followed you since the day you first stepped foot in Hogwarts, the magic that had made you different. You had never used it publicly. Never allowed yourself to tap into it in a room full of hundreds of witnesses.

Until now.

Malfoy’s body lurched.

Not by his own will, but by yours, by the ancient, crackling force curling through your veins.

The entire room gasped as he was wrenched upward, his robes twisting violently around him as though an invisible hand had grabbed him by the throat and hauled him into the sky.

He thrashed, or tried to, but the moment he moved, the spell struck.

A jolt of electricity tore through his body.

Not enough to kill. Not enough to cause permanent harm, but enough to make him scream. Or at least, he would have screamed—if he still had a mouth.

Instead, a choked, garbled sound tore from his throat, half agony, half suffocated panic, his limbs seizing as the current snapped down his spine, through his arms and legs.

And you let them watch, let the entire Great Hall bear witness as he hung there, suspended like some grotesque marionette.

And the moment he tried to move again, tried to scratch at where his mouth should be or flail his limbs, another arc of lightning danced across his body, snapping against his skin like a promise that any attempt to fight this would only make it worse.

And he knew. They all knew. He wasn’t getting down until you allowed it. But your arm didn’t waver, you held your wand high, like an executioner delivering final judgment.

Because this? This was a declaration. A statement. A message carved into the very bones of Hogwarts itself.

You do not speak against Sebastian Sallow.

You wondered if he realized that you would have done this a thousand times over. That you would have burned the entire goddamn world for him if he asked.

But before you could do anything more—before you could decide how far you were willing to take this—

A thunderous voice shattered the moment.

"THAT IS ENOUGH!"

The spell snapped. Malfoy dropped. His body crashed onto the table below, sending plates and goblets scattering, silverware clattering to the stone floor. He lay there, twitching, gasping, pathetically small as the last of the magic flickered out of his limbs.

And then—

"You."

Phineas Nigellus Black’s voice was pure ice.

You turned to face him—not a shred of regret, not a flicker of guilt in your expression.

But the Headmaster was raging. His hands were clenched at his sides, his teeth bared in fury.

The entire room was still. Waiting. Holding its breath.

"My office." His voice was low, lethal, like the words themselves were a curse. "Now."

A sharp inhale from someone at the Ravenclaw table. A hushed whisper from a terrified first-year.

No detention. No points docked. Just a direct order from the highest authority in the school.

But it was worth it, because now they knew. Every single person in this room knew.

And as you turned on your heel, heart still pounding with the remnants of power buzzing in your veins—

You caught Sebastian’s eyes one last time.

Still watching, still frozen in place, yet looking at you like you were the most devastating, impossible, extraordinary thing he had ever seen.

And then? The slightest smirk. The most faint, devastatingly admiring grin.

Like he had never, ever wanted anyone more.
