Chapter Text
Severus looks around nervously, but he only hears the drip of water on the porcelain sink and sees nothing suspicious.
He would never have come here, to this abandoned women's bathroom, but what he's up to requires secrecy from prying eyes.
Severus looks down at the cauldron settling on the burner in front of his crossed legs.
- It's time, - the corner of his lips twitches in a smile.
He stirs the bubbling potion in the cauldron three times counterclockwise.
Then he takes a flask from his robes pocket and uncorks it, turning it over the cauldron.
A pair of dark curly hairs falls into the boiling brew, disappearing into it. The potion changes color.
Severus takes his wand in his right hand and, concentrating, waves it.
The potion changes color for the last time, turning golden. Unfairly.
But despite that thought, a triumphant smile spreads across Severus' lips. It took him a long time, but he got the job done, which means he'll get his goal.
And besides... It's more like pyrite than gold. Fool's gold... It sounds fitting...
Severus lets the potion cool, then pours it into a clean vial. He holds it with two fingers and raises it higher, watching the liquid shimmer in the flickering light of the enchanted candles.
He feels impatient. Soon, he'll avenge all the insults. But he takes his time, savoring the moment.
He thought it'd be more difficult. It wasn't easy to get the ingredients, and he thought it would take him weeks to get a... piece of Potter's body.
But it was much easier than he thought. To his annoyance and good fortune at tge sami time, James Potter often ruffles his hair and pushes his curls off his forehead, attracting admiring glances from others. Black looks at him like a puppy looks at its owner. It's disgusting. Even Lily looks at him.
And Severus had to watch, too. He winced every time, but he watched intently. And less than a couple of days later, he managed to get a few hairs that had fallen from the head of this unbearable braggart.
What is it about James Potter? Why does everyone admire him so much? Why does everyone love him so much?
Today he will be able to find out. But more importantly, he will be able to destroy it all. He will make others see that beneath the foolish smile lies the grin of a jackal. That there is no kindness in those deer-like eyes, only a calculating gleam.
And he's going to start with Lily. He's not going to let Potter try to turn his friend against him again. No, today, the stupid Gryffindor is going to do something that will make Lily hate him and never look at him again.
Inspired by this thought, Severus raises his hand with the vial and downs the entire contents in one gulp.
He expects to feel bitter and disgusted, but the taste is like a complex combination of oranges, apples, caramel, hazelnuts, and coffee.
His stomach and belly are warming up, as if he had drunk firewhiskey instead of the Polyjuice potion.
A slight but pleasant shiver runs through the bottom of his stomach, his back, and spreads to his limbs, causing a slight panic to grip Severus.
He knows that the Polyjuice potion must reflect the essence of its owner. Could he have messed up and picked up someone else's hair from the desk? Some harmless Hufflepuff?
But it's too late to make a fuss.
The conversion process has begun.
He feels the robe tighten over his expanding shoulders, and his trousers tighten snugly around his muscular legs. The ends of his hair stop touching his shoulders. Instead, light curls tickle his cheeks and neck.
He doesn't need to look in the mirror to know that he's not mistaken. But he does.
A haughty expression appears before his eyes, and he restrains the already instinctive urge to turn away.
The anxiety on Potter's face looks strange. Unfamiliar. Wrong.
And the Slytherin school robes don't suit him at all. Not only in size, but also in color, in essence.
Severus should have taken it off before drinking the potion.
He pulls off his robe and shirt. Strong pectoral muscles, a sculpted abdomen, and tanned skin. A typical jock jerk. Except he's also good at school.
Severus ignores the slight twinge of envy.
He pulls off his trousers as well, trying not to look down, although he can feel that his underpants are much, much tighter.
Salazar, why didn't he change his clothes beforehand?
He's always known that Potter is bigger than him. But at this very moment... he feels it in a completely inappropriate, too intimate way.
He feels it with his own body.
He changes his clothes into a Gryffindor robe and tie, trying not to look at or touch the body he now owns.
After getting dressed, he takes one last look in the mirror to make sure everything is in order.
Potter's intense gaze, directed straight at him, sends a shiver down Severus' spine. Is he so deeply affected by fear? And what kind of fear is it that fuels his curiosity and desire to provoke? He knows all too well what fear is. Fear is what drives him to hide in the dark corners of his home, seeking to escape at every opportunity. Fear makes him silent, makes him invisibility, makes him non-provocative.
What James Potter evokes in him isn't fear.
- It’s hatred, - Severus whispers in a deep, low voice that doesn't belong to him, but is now in his power.
Pretending to be Potter is a hell of a lot of work. Severus thought he had learned all of his idiotic habits well enough, but now he realises that all of them are full of spontaneity, devoid of theatrics. When he tries to reward the second-year students who wave at him with a haughty smile, they look at him a little strangely and then wish him a good health.
Severus had hoped that he would be able to avoid interacting with others until he met Lily, but that was a naive assumption.
People gravitate towards Potter. They smile at him, wink at him, and start small talk about nothing. The Prewett brothers slap him on the back, and Severus knows that he would have fallen under that hard, friendly punch, but James' body handles it just fine.
Severus is doing his best to look like his enemy so that he doesn't get caught. Fortunately, despite the slightly surprised looks from some of the students, they don't seem to suspect anything.
He quickens his steps as he approaches the Gryffindor Tower. He can't afford to run into any of the Marauders, as Potter's closest friends would definitely notice the substitution.
Potter himself is currently on detention, and they're likely aware of this. So his mere presence here at this time will raise questions.
Fortunately, Black, Lupin, and Pettigrew aren't in the Gryffindor common room, where he joins a group of first-year students. Everyone is busy with their own activities, and they don't pay attention to him. Neither does Lily, who is also present here, as he had anticipated.
The girl sits in an armchair, reading a transfiguration textbook. Her red hair reflects the light of the fireplace, and her green eyes sparkle beneath her fluffy eyelashes.
He's never seen a witch more beautiful than her. Over the years, his friendship with her has given him strength, making him feel needed and interesting. Not so lonely. He won't let Potter ruin it all. Especially since he doesn't deserve her light, her kindness, her attention, or, most importantly, her love.
Once again, he feels a pang of guilt for his plan. He doesn't want to offend Lily. Even as Potter, even for her own good. But he's already gone too far. He can't turn back.
He looks at Lily, searching for the determination to proceed with his plan, but suddenly someone, strong enough, grabs his shoulder and drags him towards the exit of the room.
He's pushed against a hard stone wall and a face full of displeasure appears before him, gray eyes full of rage and something else.
He shudders under the gaze of Sirius Black.
- What the hell?! - Black hisses in his face.
Severus quickly looks down at his hands, which are hanging limply at his sides. They're still Potter's hands.
Has Black discovered the deception? When did he even arrive?
Severus swallows, preparing for the blow.
However, instead, pale fingers grasp his chin and lift his face, forcing him to look into the eyes of steel and storm that have pierced him so many times.
Severus is trying to find his wand in the folds of his robes. There will be an attack, and even in Potter's body, he is unlikely to be able to withstand Black's blow. And Black, possessed by Potter, will strike with full force once he realises who has dared to pretend to be his best friend.
But instead of a punch to the face, he gets a question full of pain:
- Why the hell are you staring at Lily like that?
Severus freezes, trying to make sense of what he's heard.
Is Black also interested in Evans?
He looks into the gray eyes and sees jealousy.
Well... the gears in Severus' head are turning faster... he might try to drive a wedge between the inseparable couple if they're both in love with Lily.
- I'm not interested in this boring girl, - Severus snorts, glad that he managed to convey Potter's trademark disdain. And Black, of course, will have to try to protect Lily. One word at a time, Potter and Black would quarrel.
But at these words, the Gryffindor, on the contrary, seems to calm down.
And then Severus pays attention to how close they are standing. Almost touching breasts.
Had he seen Black up close before?
Of course he had. He'd seen him close enough during their fights to know the smell of his hair and skin, the smell of blackberries and absinthe. He'd once felt his breath on his face, hot in the heat of a fight.
But he's never seen Black look at him with such love and adoration.
Severus' eyes widen, but instead of horror and disgust or jubilation at finding his opponent's weakness, his heart is filled with irrational bitterness.
He's not looking at you, he's looking at...
- James...
A hot whisper, full of reverence, slides across his lips. It's the only warning he gets before soft lips cover his mouth in a demanding kiss.
Black kisses like he knows those lips, knows their curves.
And Severus' last coherent thought is that not only Potter is Black's weakness, but Black is Potter's weakness too. They're together, and it's almost ridiculous, because they weren't even trying to hide it, but everyone... everyone, damn it, didn't see them. Their sick obsession with each other, their...
The tongue bursts into his mouth, and the hands squeeze his waist. The fingers slide under the belt of his trousers, and then grab the buckle.
These two aren't normal. Is it okay for them to do this in the hallway? Where anyone can find them? Aren't they all afraid of anything?
Severus doesn't know where to put his hands, they're still hanging silently, fingers twitching nervously. If he pushes Black away, will he be found out?
Black pulls away from his mouth. His eyes are hungry, but his voice is almost gentle as he asks:
- Are you all right, Prongs?
Severus knows this is his chance to escape. He doesn't care about his plan, he doesn't care about anything. He has to break free from Black's grip, because Black thinks he's James. It doesn't take a genius to realise that James allows him to do whatever he wants. You don't have to be a genius to figure out that Black is taking everything Potter is offering him.
But instead, his tongue, still slurred from the unfamiliar intensity of the caress, says:
- I.... yes... Sirius.
Black's eyes are shining brighter than the stars in the night sky. A wicked grin spreads across his lips. He's beautiful. Objectively. And that's not fair either. It's unfair that Severus finds his enemy so attractive.
- You never refuse me, - the Gryffindor whispers admiringly, predatory. - Damn it...
Black's grip on his hips is almost painful. He pushes Severus into a nearby niche and steps in after him, pressing his back against the wall again.
- Cast the Concealment charm, - he whispers, unbuckling Severus' belt.
Even through the arousement and curiosity that made him do this stupid thing, Snape understands that as soon as he takes out his wand, Black will immediately understand that he is not stroking James' penis through the underwear.
- I want it that way, - Severus blurts out in Potter's raspy voice, trying to infuse it with a playful, seductive tone.
Indeed, what does it matter to him if someone catches Potter and Black in the dirty act? Severus himself will get away with it.
Sirius chuckles and squeezes his cock, and Severus barely suppresses a shameful groan.
- You're such a slut for attention, Prongsie, - Black whispers in his ear, his hot breath scorching him. - Turn around.
Severus is doing this, and maybe it's even better, he won't see that face, those eyes filled with adoration that isn't directed at him. Not that he wanted to...
He doesn't understand why he doesn't try to leave, why he doesn't try to escape from the strong hands impatiently pulling off his trousers.
Is it because he knows that then Black will suspect something? Or maybe it's because he's the spoiled, vicious boy his father calls him.
His legs tremble with arousal as the cool air brushes against his bare buttocks. He places his hands on the wall to maintain his balance. He can feel Sirius' sharp gaze sliding over his... no, James' body.
Black would never look at him like that. Oh... he'd be furious if he found out he'd made love not to his precious Potter, but to his enemy.
But what about Severus himself, who seems strangely desperate for Black to continue what he started?
Lips cover his neck and the back of his head with kisses, and Severus moans, wondering whose sensitive spots these are. Or maybe he and Potter share them?
Slightly rough palms cup his ass, caressing and kneading it, obviously enjoying the elasticity of the semicircles and the velvety texture of the skin.
How far did these two go? Did they fuck? All of this suddenly arouses Severus' curiosity and fantasies. Merlin, who would have thought he'd ever imagine Black fucking Potter?! And who would have thought he'd let Black fuck himself?
Severus can't help but chuckle.
- What is it? - a low voice calls from behind him. Fingers dig into his flesh and spread his cheeks.
Severus feels a gaze on his arsehole. He wonders what Potter's hole is like? Tight, or always ready for Black?
- I wonder if you fell asleep there, - Severus replies boldly. He can't stand there forever. The potion doesn't last forever, and if he...
All thoughts vanish from his mind when he hears the sound of a loud spit and thick, warm saliva drips heavily directly onto his hole.
Before Severus can complain, Black immediately inserts a finger, and Snape moans with the unfamiliar sensation.
- Insatiable, - Sirius whispers into his neck, moving his finger back and forth. - Stop moaning like a virgin, or they'll hear us before I get my dick inside you.
"I am a virgin," - Severus wants to snap back, but of course he can't. He can, however, moan, because Black's finger touches that spot inside him that makes him shudder with pleasure. Curiosity gives way to a thirst for more. Potter's slutty waist bends as Severus tries to impale himself on the fingers, now two.
He has to admit that Black knows what he's doing when he rubs his prostate at the perfect pace.
Severus feels dizzy and loses all shame. He doesn't care who does what to him. He just wants it to continue.
But deep down, he knows he's lying. He cares.
He cares that the hands that usually hurt him now give him pleasure, that the lips that usually curse him now shower his neck and shoulder blades with kisses. That the voice, the scent, and the silky curls brushing against his shoulder make him more aroused than when he jerks off in the shower.
- Love, - a hoarse voice whispers in his ear. - Touch yourself.
The words combine with the circular motion of the fingers over his prostate, and Severus screams.
- Come on, - Black whispers urgently, his lips grazing his earlobe, pulling it into his hot mouth.
Merlin... God!
Severus presses his cheek against the wall and lowers one hand to the bottom. He slowly takes James' cock in his hand, it's big and hard... so hot. And the first touch gives him an extraordinary pleasure. He strokes himself, and Sirius groans behind him, accelerating his finger movements.
Potter's cock throbs in Severus' hand, and he comes, letting out another scream.
Fingers slide gently inside, prolonging his orgasm as a copious stream of semen spills onto the stone wall.
Sirius pants behind him, and Severus is too weak to even move. He rests his forehead against the stone, gasping for air.
- Wow, I've got a great ass! - a suddenly, a cheerful and cocky voice comes from behind him, ruining the intimacy and mystery of the moment.
All the lightness and relaxation disappear from Severus' body, and he quickly turns around, trying to pull up his trousers and underwear, but his legs get tangled, and he slides down the wall, covering his body with his robes and knees.
And he sees something that makes him freeze for many reasons.
Black's dark gaze is fixed on him. His trousers are bulging with arousement. And a smirk plays on his lips. An equally predatory smile plays on the lips of James Potter, standing next to Black.
The real Potter wraps his arms possessively around Black's waist and stares at his own reflection with a mocking expression. Neither of them looks surprised, nor do they look angry. Instead, they appear like two lions playing with their prey.
Severus straightens his shoulders to regain his confidence.
His fingers search for his wand in the folds of his robes.
Sirius chuckles, noticing his unease.
- Well, Sevvy? Did you like it?
Severus frowns darkly.
- When did you figure it out?
At this point, the effects of the potion stop, and his knees turn pale and sharp, as does his entire body. And there're traces of kisses on his pale neck.
- James screams my name when he comes, - Sirius snorts with a chuckle. He openly admires his work.
Severus warily looks from one Gryffindor to the other, so as not to miss the moment when their fun turns to anger and a fight begins. If he was fast enough, he could escape. That's just... His legs are still slightly trembling from the orgasm he just experienced. The most intense and vivid orgasm of his life.
- You fucked his brains out good, Pads, - Potter smirks, his hungry gaze roaming over Severus' exposed skin.
Sirius lets out a barking laugh.
- Next time, turn into me. James sucks like a champ, - he smiles, baring his canines.
James is laughing this time.
- I don't mind doing it to myself. Conquering new peaks.
He squats down in front of Severus and wipes the saliva from Snape's lower lip.
Snape's hand freezes with his wand in it.
The tenderness of that touch almost baffles him.
- Although..., - Potter's gaze drops down and then rises again. - I bet you'd like it better if I put this cute little thing in my mouth.
Severus blushes under the penetrating gaze of those hazel eyes.
- Let me go! - he blurts, jumping to his feet and clutching his robes to himself.
James stands up after him. Sirius wraps his arms around his waist and rests his chin on Potter's shoulder. He looks almost innocent, if not for the fact that his hips are grinding against James' backside at that very moment.
- The price of freedom is one kiss, - Potter tilts his head to the side and taps his lips with his index finger a couple of times. They are plump, unlike Black's thin lips.
- Sod off, - Severus mutters through clenched teeth. Unbidden thoughts of those lips on his cock come to his mind.
James rolls his eyes. Sirius snorts behind him. He lowers his head and kisses Potter's shoulder, looking at Severus through his eyelashes.
- You kissed my boyfriend. Do you want to kiss me?
They're both crazy. Severus has always known this, but now... he realises that the world is a game to these two...
- James, - Black whispers impatiently, but Potter doesn't take his eyes off Severus. Something hard appears in his mischievous gaze.
- Come on... one kiss and you're free. And I won't even be mad about this your masquerade.
Severus wonders what the chance is that he can beat the two of them if it comes to a fight.
But then Black laughs softly.
- You're not mad. You just can't stand it when I get something first, Prongs.
James turns his head towards his friend and, obviously, lover and grins.
- Okay, you got the first kiss, Pads. I'll get the first of something else.
This threat, this promise... makes Severus' exhausted cock twitch.
Fortunately, these two are too busy with each other, communicating silently through their eyes.
Severus takes advantage of this and breaks out of the niche, pushing them aside.
They still don't look angry, and, surprisingly, they don't follow him. Sirius even has a hint of joy on his face.
Potter blows him a kiss before Black pulls him into the niche by the belt loop on his trousers.
Severus blushes and escapes.
Part of him wonders if Potter kisses as well as Black.
Something tells him that one day he will know the answer to this question.
