THE PLOT TWIST SHUSJSJSJ

ofc our handsome devil brewed the potion😭

diesel is desire (we were playing with fire) ; sebastian sallow

pairing sebastian sallow x f!reader word count 4k synopsis sebastian sallow is a good friend. so good, in fact, that when you find yourself under the ungodly influence of a lust potion, he's willing to help give you some relief. content contains seventh year au, dubcon (under the influence of lust potion), darker take on seb's character lol <3, breeding kink, creampie, possessive!sebastian, possessive sex, virginity loss, babytrapping

“Why did you go out of your way to avoid me?”

An accusatory voice momentarily breaks you free from the overwhelming feelings you were struggling to deal with, but the voice is too familiar.

The source? Sebastian Sallow — a very disappointed Sebastian Sallow, which after two years of friendship (and the lingering what-if of becoming something more), you’re able to identify as a Sebastian that you would much rather not be dealing with. Particularly because, try as hard as he might, he’s rather prone to saying harsh things and treating you unkindly whenever he gets into one of his moods. The hurt expression on his face is barely concealed by the scowl that mars his otherwise handsome features.

Don’t think about how handsome he is!

Instead of replying to him, you’re quick to turn your head to the side, trying to focus on the curtain that separates your cot from the others in the infirmary. It’ll do no good to engage with Sebastian right now — not whenever the reason you’ve been compelled to check yourself in to the school nurse is purely because you’re not sure if you have enough self-control to stop yourself from literally ripping his robes off of him.

But it’s not like you can tell him all that. Lying would be preferable, if only Sebastian wasn’t so attuned to you and every single one of your tells. If you attempted lying to him, who knows what more damage you would cause? Then again, blatantly ignoring him also seems equally dangerous, especially with how quick to irritate he’s been lately. Ever since you witnessed him literally murdering his uncle, the relationship between the two of you has grown stronger — being practically partners in crime will do that to a friendship — but also more… volatile. The charming fifth-year you met on your first day of school still remains, but you have long since realized that there’s more to him than meets the eye.

On the surface, he’s nothing but affable. Maybe a bit of a rebellious streak, but it’s all in good nature. In the beginning, it was fun being with him. Exciting, even. Then you started following him on the dark path he paved all by himself, and before you could realize that you were in too deep, it had already been too late to turn around. Now, the seventh-year boy standing by your cot seems so different from the one who lives on only in your memories.

“Don’t ignore me.” He means to make the words come out sharp, irritated. It resembles more of a plea than anything, and you shut your eyes, willing him to leave. It must be all in your head, but you swear you can smell the familiar scent of him: cool mint mixed with the light musk of whatever cologne he’s been favoring since the fifth year.

“Sebastian, I’m not feeling very well.” You mumble, hoping it’ll be enough to get him to leave you alone. It’s not a lie. You aren’t feeling great whatsoever. Not even the nurse, bless her heart, can figure out what’s become of you. She gave you a pitying look and an almost amused smile as she explained that — in her words — sexual urges are very normal for girls your age.

If your body wasn’t already overheating, you’re certain your cheeks would have instantly turned hot from sheer embarrassment.

“Well, why wouldn’t you tell me that instead of abandoning me the whole entire day?” Sebastian is many things with different people. With you, he is both guarded and vulnerable. Some days, when you’re not feeling your best, his emotions versus his actions can give you whiplash. He has the audacity to say something like that all the while, he sounds absolutely tortured over the fact that he had to go eight hours without your presence.

As if realizing the harshness of his attitude, he softens his tone as he asks, “Are you feeling any better?”

You had gone to the Great Hall before him because you needed to review your History of Magic notes before the test today. All you had was a bit of pumpkin juice and toast, and all had been well until you started feeling warm underneath your robes and sweater. As the heat began to travel through your body, you found it hard to concentrate on your notes. Not because of the heat, but because of the many thoughts swirling around in your head. Flashes of Sebastian that started innocently enough and quickly morphed into daydreams of him without his uniform. Sebastian with his hair messed up from the way your fingers tugged at the strands as he satiated his thirst with the juices flooding between your legs. Sebastian who would prioritize your pleasure over his and could make you cum multiple times before even thinking about getting his dick wet. Sebastian—

—who you share most of your classes with!

You knew right then and there that something had to be wrong with you. Sure, you’ve thought about him sometimes, but never to that degree. And certainly never at seven in the morning over breakfast and history notes.

That’s how you ended up lying in a cot in the infirmary, trying your hardest to ignore the intrusive thoughts of Sebastian fucking you ‘til you can’t walk anymore.

“No.” You practically moan out the word, and you’re hoping to play it off as just you being a baby about being “sick”.

You don’t expect him to turn your head so that you’re staring up at the ceiling, and you certainly don’t expect him to press the back of his hand against your forehead. His hands are cold, but surprisingly enough, it brings you some sort of relief from the fever that has seemingly overtaken your body. You bite back another moan.

“You’re burning up.” Gone is his attitude. Instead, it’s been replaced by your favorite Sebastian — the kind, caring one. The one that resembles the boy you first met. Sometimes, his care can be suffocating, but when you find yourself craving nothing but him and his touch, you don’t mind his invasion of your personal space at all. “Are there any other side effects? Does your throat hurt? Stomach? Tell me what’s the matter.”

You know how Sebastian must feel when it comes to people he cares about falling ill. His sister has only made him more paranoid about the severity of sickness and curses, and the concern and fear etched upon his face makes your hardened resolve of keeping the sordid details of your affliction to yourself melt away.

“Don’t laugh…” You warn him, but your voice seems so small and maybe even a little scared that his expression turns even more serious.

“Never.”

“I think… I think something happened to me. A charm…” You’re careful to dance around the word curse, lest Sebastian accidentally blows up the whole entire infirmary due to his emotional state. “I just feel very hot. And, um, I think the only relief would be to—”

You can’t even say it. You can barely even explain it since you don’t really know what’s happening either.

“I’mfeelingverysexuallyfrustratedandIhavenomeansofrelief!”

The two of you know that you’re never going to repeat that phrase ever again, and you’re practically near tears after that little confession.

“Oh.” He says, as if this is nothing more than a simple, casual conversation and not the most humiliating situation ever. “Why didn’t you tell me sooner?”

“Be-because it’s embarrassing!” Has he really no shame? Who would willingly admit that out loud?

“You know, I’ve heard rumors of some sixth-years trying to pull pranks by spiking the juices with love potions. Just really gimmicky concoctions, truly. Nothing too severe. Hmm… You must have a sensitivity to it, though.” Sebastian’s musings do nothing to bring you reassurance. If anything, it just makes you want to hide. If the universe is truly kind, a sinkhole will emerge from nowhere and swallow you whole. Yes, that sounds lovely right now.

Instead, the universe is sick, because what else could explain Sebastian telling you,

“If it’s relief you need, I’d be happy to help.”

Sebastian is many things to you — a dear friend, a confidant, a literal partner in crime — but none of those things involve him having sex with you, even if the offer only came from some odd sense of duty.

And that’s what this is, isn’t it? He probably feels indebted to you since the fifth-year. Maybe even anxious, too. You could expose him at any given moment, and maybe that’s why he’s been so keen on attaching himself to your side ever since. This is a humiliating predicament to be in, and Sebastian doesn’t seem like the type to kiss and tell — considering that you don’t even know the names of girls he’s been with before is evidence.

Besides, you’re only feeling incredibly needy for one person. You can accept his offer, but you’re certainly not going to let him know the truth: that only he is the one who can help you.

“Don’t be embarrassed.” His cool hand is now cupping your face, thumb brushing against your cheekbone in an almost gentle manner. Sweet Sebastian is making an appearance, perhaps to try to put you at ease. You like this Sebastian. “Just let me take care of you.”

When the haze of lust clears from your sex-addled mind, the rush of consequences will burden and crush your very conscience.

Fortunatenly enough, consequences are clearly the last thing on your mind.

It would appear that the only thing you can truly focus on is Sebastian and what his idea of ‘taking care of you’ is.

The Sebastian staring greedily at you is an unfamiliar Sebastian. You’ve become accustomed to the many variations of himself: Angry Sebastian, who says the most vile things out of spite and usually misguided anger; Remorseful Sebastian, who is quick to grovel (he’s quite good at groveling, really) and wants nothing more than to be back in your good graces; Happy Sebastian, although there are variations upon this very variation — the trick to seeing whether he’s pseudo-happy or not is all in his smile (the fake one is eerily perfect, the real one is crooked and a rarity). This Sebastian, though…

Hungry.

The word doesn’t quite explain the dark glint in his eyes or the way his hands are almost reverently stroking your body. Your skin felt so, so hot just a few minutes ago — then again, just a few minutes ago, you still had your school jumper and blouse neatly intact. Now, you’re laid practically bare, prey to Sebastian’s more-than predatory gaze.

If the two of you weren’t such great friends, you might have had enough sense to be scared.

The only articles of clothing left to protect your dignity and shield you from his eyes are your skirt (which is already riding up to expose your thighs due to his wandering hands), your white cotton panties, and the matching bra.

“How do you feel now?” He asks, and you want to tell him you’re still feeling embarrassed, but his hands feel surprisingly nice on your skin, and you can’t help but hunger for more. Perhaps the look in his eyes, the one you couldn’t quite find a proper name for, is the same look you’re giving him.

“More.” You whimper out, not caring if you sound selfish or impatient. This is awful. The two of you should put a stop to… To whatever the hell this is! This is a horribly unbecoming, unsavory situation you are in, and if things progress like how you think they are going to (how you want them to), then you’re both dead once all the adults find out. Professor Weasley would probably force the two of you to be wedded within the next day of her finding out, not to mention that the headmaster would probably have the both of your heads on sticks.

But you don’t tell him to stop because your rational thought is slipping, much like your bra. You’re viewing everything almost as if in a trance, almost as if this is happening to someone else and not you. But it is very much you; it’s your nipples hardening after being exposed to the cool air of the infirmary. It’s your bra that Sebastian tosses to the side. He’s licking his lips, eyeing the expanse of skin that has been revealed to him. In ordinary circumstances, you’re certain you would make all attempts to cover yourself up and try to regain some sense of modesty.

In these circumstances, you practically arch your back and mewl out for more, more, more.

More touching. More skin-to-skin contact. More of Sebastian. You want him. All of him. Every part of him. You want his cock ramming into your cunt, you want his hands wrapped around your throat, his mouth spewing out words of filth right into your ear. Most importantly, even though all you can seemingly focus on is having him ravish you, you can’t help but to be greedy and dare to hunger for more. You want his secrets — all of them. You want to know the nightmares that plague him, and whether he’s full of regrets, just like you. You want to have a claim to his soul, just like how he already has a claim to yours. You want to know that when his heart beats, it is calling out for you.

“I’m going to kiss you now.” He announces, like he’s waiting for you to protest. He’s not directly asking, but the question is still there, as is the warning. Can I kiss you? If you let me, there’s no going back.

“Please.” You whimper, completely and entirely at his mercy.

“Say it.” Sebastian swallows hard, almost as if he’s also nervous and too charged up with desire. His fingers are loosening his tie. He has already shrugged off his robes.

He doesn’t tell you want to say, but you already know what he wants to hear. The words have been resting on the tip of your tongue this whole entire time, anyway.

“I want you to— to kiss me, and more…” You look into his eyes. The lights in the infirmary make them appear a lighter color than usual. “I want more. I want you, Sebastian.”

The moment the last confession slips from your soft lips, Sebastian’s mouth descends upon your own. His body is angled awkwardly, trying not to crush you with his weight, but you can feel the heat emanating from him all the same, even despite the layers of his clothing that separates the two of you.

You think the world stops spinning when his lips slot against yours. He tastes like the pumpkin juice from this morning, sweet and refreshing. There’s a lingering taste of spearmint toothpaste. You want to keep kissing him forever. You want him to kiss you everywhere else. When breathing becomes a necessary thing, he stops. You frown. You didn’t want him to stop. Oxygen is overrated, anyway.

He lays a hand against the pillow you’re resting on, staring down at you, want clearly displayed on his visage; desire is etched onto every facial feature, and his eyes are gazing so intently into yours, you wonder if he’s a Legilimens.

“Promise me you won’t regret this. Swear that you truly do want this.”

He must not be a Legilimens, then. It’s so clear you’ve been in… It feels odd to admit it. Wrong, even. But it’s the truth—

—you’ve been in love with him since the fifth year.

You don’t keep someone’s secrets, their crimes, to yourself when you don’t love them. You let him perform Cruciatus on you, and you forgave him. No — you didn’t. Because you asked him to. There was nothing to forgive. You would endure it, over and over and over again, just for him, only him. And to think, you’re flooding your panties just at some simple fantasies of him, and he has the nerve to believe you don’t want this? Don’t want him?

“I promise. I swear it to you. I want this entirely.” And maybe liquid courage had been slipped into the juice you’ve consumed as well because you find yourself admitting, “I’ve always wanted to do this with you. If it… If it had to be done the first time around, I would always dream of you doing it to me.”

He stops breathing, just for a moment. Gapes at you, even.

“Y-you’re a virgin?”

You wonder if you’ve gone off and ruined the mood. You wonder if you should take it back, say you were just joking, but before you can, his lips are pressing against yours once again. This kiss is even hungrier than the last, and you’re not quite sure how that’s even possible. It’s almost as if he wants to devour you whole.

“Thank you.” He gasps out, so close to you that his breath tickles your nose. “Thank you for entrusting me with this, love. I promise I’ll make it good for you, just as you deserve.”

And suddenly Sebastian is just everywhere. His sweater is discarded on the floor, right next to your bra and his tie. His belt is unclasped; he hasn’t even bothered to remove it entirely, just displaced it enough to where he can unbutton his trousers, and he’s pulling it down — his pants, that is. And the briefs. He hasn’t entirely disposed of everything, just partially. Meticulous Sebastian Sallow who is now so far gone into lust and depravity that he cannot even handle wasting another second by removing himself entirely of his clothes. You have made a man into a beast.

But you see the way he’s eyeing you — all dark hair and sharp teeth. He flips your skirt up, exposing your damp panties to him, and he licks his lips again, and you realize — perhaps too late, or perhaps you’ve known all this time — that Sebastian has always been a bit of a beast. A wolf only coyly imitating domesticity.

“You’re so wet.” He brushes a finger against your cotton-covered folds, and you shiver.

Yes! Your body seems to cry out. More, more, more! Your back arches, keening, craving his touch. You’re soaking through the fabric, making it practically translucent. You’ve never been this wet before in your life. You’ve never wanted his touch more badly than you do now.

“For me.” He mutters, but in the silence of the infirmary, you hear him all too clearly. “Is this all for me, love? Have you been like this all day?”

You nod, not trusting yourself to form coherent sentences. Even if he’s not staring at your head, far too fixated at what’s between your legs, he hums his approval.

“Don’t worry, my love. I’ll make it all better.”

He’s kissing you. He’s got your panties only pulled to one side, and you think he’s muttering apologies against your saliva-coated lips. Something that sounds awfully like sorry, so sorry, but I can’t wait, and I don’t think you can, either. You barely catch a glimpse of his cock before you can feel the sharp heat of his length against your inner thigh. You would have thought that there would be some preparation, especially since this will be your first, but you’re thoroughly soaked. You’re aching for a sensation you have never felt before, but the animal inside of your brain is telling you, instinctually, to seek Sebastian out. That Sebastian will make it all better. That’s what he said he’ll do, and he’s kissing you, and he’s apologizing, and—

—and the world stops spinning.

No. There’s some slight resistance at first, your poor cunt protesting at the intrusion. A second later, and he’s slipping in half of his length with considerably more ease. A few inches more, and his hips are pressed against yours, and oh— Oh, it’s like you’re made for him. There is no resistance. There is no pain. There’s just you and him, and your body is welcoming him home. Where has he been? It seems to ask. Please don’t ever leave again.

“Fuuuuck.” He hisses it out, and his teeth are gritted, and he’s admiring you. His eyes flicker to your face, down to your breasts, down down down right to where the two of you are connected. The word comes out broken, and yet, drawn out. As if he’s struggling to speak.

Then he starts thrusting, and suddenly you realize that the world hasn’t ceased its spinning. No — now it’s moving entirely too fast. It must be off its axis. You feel otherworldly. You feel like this pleasure, this overwhelming, absolutely delicious pleasure, cannot simply exist on earth. It should be impossible. It should be impossible to find comfort and rapture in the way the tip of his cock seemingly kisses your cervix. You expect pain.

You only find mindnumbing, earth shattering pleasure.

You feel stretched beyond your limits. You hear his pants and his groans, and you’re moaning, too. Calling out his name, which is so silly, he’s right there, he’s right there. There, at that special spot, at the spot you’ve never been able to discover on your own. You now know why adults advise so heavily against these type of relations — it’s simply addicting. You don’t think you can stop; you don’t think you want to stop.

“Oh, fuck. Fuck, you’re so good f’me. Such a good girl. My good girl, aren’t you?” He’s rambling. His thrusts are considerably sloppier, and you feel his thumb brush against your clit, and you arch your back some more, practically screaming out his name. The stimulation is too much — it’s not enough — and you will always crave him. “Tell me. Tell me that you’re mine.”

There’s something so, so addicting about his possession. About being treated like his possession.

“Yours. M’yours, Seb. All—” You can’t finish your sentence. The pleasure is becoming too much, and you’re too sensitive, and he’s doing this thing, this absolutely amazing thing, where he rubs circles on your clit in tandem with his harsh thrusts, and you’re cumming. You don’t ever want to come down.

He feels you cum, sees your juices drench his cock as he pulls out, only to push right back in, relishing in the feeling of your contracting walls. He leans down, biting on your neck, and you take a hand to grip his dark hair, still cumming, and now he is, too. Spurts of his cum are flooding into you, painting your walls, successfully staking his unrivaled claim on you. You have been compromised. If anyone were to find the two of you out, you would have no other choice but to take his hand, his ring, his family name, him. You would have to take it all.

Coming down from his high, he has enough kindness left in him to lick at the wound he’s left on your neck. Your eyes are fluttering close, the intensity of it all thoroughly exhausting you. You don’t know the thoughts swirling in his mind. You don’t sense the longing behind him stroking your stomach, wondering if the Felix Felicis — his bottled Liquid Luck he’s spent forever brewing — has done its job. It would surely be very lucky, indeed, if his seed takes this first time around.

Your breathing slows, and he feels your heartbeat even out. You’re exhausted, poor thing. Perhaps he had been too rough.

He’ll apologize, he decides, by doing something that’ll benefit the both of you. He ought to clean you up, get you tucked in, and when you wake, he’ll go down on you. He bets you taste so sweet, so innocent. He had known, of course, that he was your first — that he was always going to be your first. Your only.

He wonders if the effects of the lust potion will still linger in your system even after you wake up. Probably so — he did it brew it quite strongly.

But the adoration, the love, in your eyes is something no amount of skilled potioneering can create. No; your feelings for him are real. You just needed to lower your inhibitions to get to the confessional stage.

And now that you have confessed…

Sebastian Sallow can rest well after confirming what he’s known ever since he first laid eyes on you:

You’re his.
