Chapter Text
It was late. Far too late to still be up and roaming the empty corridors of the castle. Sebastian knew what he risked if he got caught, he knew what you risked too but he simply didn’t see any alternative this time, it was an emergency.
“Will you tell me where we are going now ?” You asked him, walking behind him, close enough to benefit from the light of his wand, guiding his steps in the dimly lit halls.
He stopped in his tracks and you bumped into him with a thud. He turned around to look at you with a disapproving look, raising a finger to his lips to ask you to be quiet and you rolled your eyes at him. It wasn’t your fault, the least he could have done was warn you that he was going to stop so abruptly…
He froze, carefully listening to the sounds of the castle in the night, making sure no one was around to catch you breaking school rules. Again.
Once he decided that it was safe enough to continue, he started walking in direction of a wooden door you recognized with surprise.
“Mrs Weasley’s office ?” You exclaimed, as quietly as you could. “Is this how you are planning to help me out ?”
“She threatened to not let you finish the school year if you failed her preparatory exam.” Sebastian justified, reaching out to try to open the door but of course, it was locked. “What else can we do ?”
“Oh I don’t know, study maybe ? Try to keep up with homework ? Take more notes in class ? Anything but breaking into her office in the middle of the night!” You responded, scandalized that he’d take such a careless risk. Did he not realize that you both were very close to getting expelled from Hogwarts for various reasons ? Adding breaking into a professor’s office definitely wouldn’t help your case.
“I’ve heard your answers when Ominis quizzed you on the subject this evening, it was catastrophic.”
“You aren’t exactly the best at transfiguration either.” You snapped back, vexed by his remark.
“I’m good enough to not fail my exams.” He retorted, before attempting to open the door with an Alohomora spell but it remained locked, probably protected by a charm. “Crap.”
He took a closer look at the lock, looked around to both sides of the corridor to make sure that no one was in sight and took a step back, outstretching his arm to protectively guide you behind him.
“Make sure you stay behind me.” He told you, raising his wand in front of him.
“Oh no, Sebastian, don’t you dare !” You said, knowing exactly what he had in mind.
“Confringo !” He shouted and flames bursted out of his wand, crashing against the door in a thud and setting the old wood on fire.
There’s no way you wouldn’t both be expelled after this.
You watched helplessly as the door consumed itself enough to let you in and followed Sebastian inside the office with resignation. Might as well go for it now that you were here…
“Lumos.” You whispered, at the same time as he did, once inside the dark circular room that Professor Weasley used as her private office between classes. It wasn’t big but there were a lot of items around, shelves against every wall filled with books, parchments and relics. A large desk in the center of the room, with pieces of papers and files neatly piled up. Some heavy looking chests on the floor, sealed by large locks. You weren’t sure where to start. “What are we even looking for ?”
“The answers for the upcoming exam.” He replied, almost casually, as he started rummaging through the papers on the desk. “I know she keeps them somewhere around here.”
You turned to the shelf closest to you, surveying the different books lined up and taking a closer look at a strange and ancient looking relic on display. Sebastian opened each drawer of the desk one by one, shamelessly invading your professor’s privacy with a desperate expression on his face. It almost seemed like he cared about you succeeding at this preparatory exam more than you did… But why ?
You focused on your task, quickly going through the parchement papers piled up in front of you but you didn’t find anything helpful. You turned to look at him, now searching the shelf on the opposite side of the room. You could tell the more minutes went by, the more agitated he became, audibly groaning in frustration each time his rummaging proved unsuccessful.
You were about to tell him that you both should head back to your dorms, that it didn’t matter that much and most of all, he shouldn’t be breaking the rules for your sake but a commotion behind what was left of the door made you freeze in place. You exchanged an alarmed look with Sebastian as you both stayed perfectly still, listening to your surroundings.
“And what do we have here ?” Peeves’ loud voice suddenly boomed, resounding against the walls.
“Crap.” You heard Sebastian groan, letting go of what he was doing to catch your hand and pull you towards the door. “We need to go !”
You let him guide you out of the office, not even bothering to cover your tracks or repair the door you had destroyed on your way in. It was no use, now that Peeves had seen you, you were surely going to be sent to detention. Or expelled.
“I think I saw the caretaker in the hall, he’s going to catch yoOoOoOou !” Peeves shouted, his airy form following you as you both ran through the empty hallway. “Mister MoOoOoOoOoOn !”
“Shut up, Peeves !” Sebastian yelled but it was no use, the poltergeist enjoyed nothing more than to tell on your friend and see him get punished for his infractions.
You ran hand in hand under the alcoves and up a spiraling staircase, the ghost still following you with loud bursts of laughter resonating in your ears.
“Here !” Sebastian exclaimed, pulling on your hand to ensure you took the same sharp turn as him. He stopped in front of a large door you didn’t recognize and opened it with no hesitation, pushing you inside a dark and narrow supply closet before joining you there, quietly closing the door and plunging you both in total darkness.
You both held your panting breaths as the loud ghost flew by in the hallway, waiting until his voice faded to breathe again. It’s only then, in the absolute silence of the castle that you realized how close you were from each other, your body pressed against his as his warm breath softly caressed your skin.
“Do you think it’s safe to get out now ?” You asked him, your voice a whisper in the dark.
“He said Mister Moon wasn’t far, I think we should wait it out a bit longer.” He replied, his usual confidence replaced by an hesitant tone, as if being so close to you was unsettling him more than what he would have expected it to.
You cleared your throat awkwardly, outstretching your arms as far as you could to assess the space you truly disposed off. You barely had enough room to take a step forward before your body pressed against the wall but at least it put a few inches of distance between you and Sebastian. You both still were panting, the sounds of your ragged breaths filling the narrow supply closet. You could feel the warm air leaving his lips hitting against the exposed skin of your neck, causing a shiver to run down your spine. You closed your eyes, leaning your forehead against the cold stone wall to try to distract yourself, your mind - and body - extremely aware of the proximity of him behind you.
An echo of Peeves’ laughter resounded in the distance, making it clear that it still wasn’t safe to come out of your hideout.
“Stupid poltergeist.” Sebastian breathed, the animosity he felt towards the ghost who loved to snitch on him very audible in his tone.
You kept quiet, hoping you’d soon get an opportunity to exit the all too small closet, because your heart was racing in your chest and you couldn’t help but feel a shudder of excitement coursing through your entire body each time a part of Sebastian brushed against you, like a teenager desperate for something more. It was embarrassing.
But not as embarrassing as the thing currently poking your lower back.
It was his turn to awkwardly clear his throat, attempting to back away as far as he could but the erection that had grown into - and now outstretched - his pants still touched you.
“You know, maybe we could try to pass the time in a fun way.” He suggested, obviously deciding to own up to the situation.
“Sebastian.” You said, trying to sound scandalized by the implications of his proposition and his very noticeable arousal but it came out all wrong, more like a whispered moan and less like the patronizing sigh you were going for.
He took a step closer and you felt the full length of his cock pressing up against your back, the heat radiating from underneath the fabric of his pants piercing through your skirt to warm your own skin up. He placed a hand on your hip, careful at first, and as innocent as he could be, gently caressing its way up your waist with a slowness that made it seem like he was waiting for you to protest… But you didn’t.
Getting bolder because of your silent approbation, he snaked a hand under your skirt, caressing the bare skin of your thigh before moving to your center. You leaned back against him, your heart racing and your breathing pant up. Rationally, you knew this was very wrong, but in the darkness and the narrow space forcing you against each other, it felt so right.
“Getting caught in such a compromising position, added to sneaking out past curefew and breaking into Professor Weasley’s office will probably get us expelled, I don’t think we should risk it.” You finally managed to say, although your body was melting under his fiery touch.
“We may have broken a few rules tonight but they can’t say anything about this, we’re both adults.” He replied, his voice low against your ear, making you shiver once more.
“It’s written in the official school regulations; no intercourse or other sexual misconduct will be tolerated in the castle.” You informed him, a gasp escaping from your lips as his fingers slipped under the elastic of your panties, sliding downwards between your thighs to where you were already wet with anticipation for his touch.
“In the castle… So you’re saying we should hook up outside next time ? Like out of the astronomy tower ? Or in the gardens ? The front courtyard ? Technically we could even do it under the bleachers of the quidditch pitch...” He retorted, playfully, while his fingers applied pressure where you so desperately needed to feel it, earning a soft whimper in reaction.
He buried his face against your neck, placing a wet kiss on your pulse point as he massaged your clit with ease, tugging on your hip with his other hand to get you to grind against the impressively hard buldge in his pants.
You weren’t sure how long it lasted, nor did you remember to be quiet, shamelessly moaning as he brought a finger to your entrance and your grinding against him allowed you to control the speed and depth with which it slipped in and out of your pussy.
You enjoyed the way he breathed loudly against your neck, the tiny gasps dropping from his mouth each time the pressure you applied against his erection caught him by surprise. A pleasant surprise.
You knew you shouldn’t want more. Shouldn’t want him. But it felt too good to stop and you both were already too far gone to even try so you didn’t stop him when his hand left your panties to focus on sliding them down your thighs instead, before pulling your skirt up to your hips.
“We shouldn’t.” You whispered, a moment of lucidity in your thoughts, probably sparked by the sudden vulnerability you felt now that your underwear had been removed. Good thing Sebastian couldn’t see you in the dark, otherwise he would have laughed at how red your cheeks probably were by now.
“Why not ?” He asked, interrupting his attempt to open up his pants and focusing his full attention on you.
“Because…” You started, but suddenly couldn’t think of any real reason as to why it wasn’t a good idea, except for one. “Because we’re friends.”
He laughed and you felt his hand on your chest moving upwards to your neck until it reached your chin. He turned your face in his direction, leaving merely an inch of space between your lips and his.
“We’ll still be friends after that.” He promised, pressing a kiss on your mouth that was everything but friendly. It was a passionate, eager and hungry kiss. Desperate even, and just like that, your only good reason to stop him seemed completely unjustified. You could allow it to happen, you could hook up with your best friend without instantly losing him, there was no harm in having a little fun after all, you both were two consenting adults.
You returned his kiss and pressed your back against him, making him understand that you had no more objections and you felt him smile against your lips, triumphant.
He parted from you to finish unbuttoning his pants, pulling his hard cock out of them. He guided it between your legs, the tip instantly gliding between your wet folds when he stepped closer, easily finding its way to your prepared entrance. However, his erection was much bigger than his finger and you gasped in shock as it slowly stretched you out the deeper it went in. You braced yourself with your hands against the wall in front of you for support, whimpering pathetically when his full length was shoved inside you, making you feel incredibly full and hot.
A few obscenities dropped from his lips, mixed with groans and gasps as he moved his hips back and forth to create the friction you both so desperately craved. With his hands on each of your hips, he guided you in rythym to add in some intensity to his own thrusts, making sure that you’d meet him ready whenever he sloppily pushed forward, his tip hitting as deep as it could inside your wet pussy.
It felt good, and the pleasure building up in the pit of your stomach kept intensifying with each of his thrusts. You weren’t aware of much else except of how perfectly he fitted inside you, how your own walls were contracting around him the closer to climaxing you got, and faintly - very faintly - of the distant sound of a poltergeist’s voice in the empty hallways.
At least Sebastian could still think clearly enough to remember the reason why you had ended up in such close proximity in the first place, and how crucial it was that you did not get caught. Especially not now that he was so recklessly fucking you from behind. So one of his hand let go of the grip it had on your hip to cover your mouth, muffling the sound of the moans you didn’t even realize that you were letting out, and effectively silencing your cry when the pleasant sensation in your body exploded into pure bliss.
Then, it was his turn to struggle with keeping quiet. He bite down on his lower lip as hard as he could when the tightness of your walls around him became way too intense to bare, causing him to shoot his load deep inside you. He filled you up with his cum, unable to stop himself, another obscene word dropping from his lips as he realized how imprudent it was.
Once he was done and your body relaxed enough to allow him to pull out, he took a step back and leaned against the wall, chest heaving and vision blurry. You were panting too as you reached down to pull your panties back on, feeling his release dripping out of you and already soaking the fabric. You adjusted your skirt and your hair, although you weren’t sure it mattered that much. Not in the darkness of the supply closet at least.
Sebastian’s ragged breathing slowly came back to normal, you heard the sound of his pants and the way he shifted to tug his shirt back inside them, making himself presentable again as well. Then, without a word, he cracked the closet door open and took a tentative look around.
With the corridors apparently cleared, he stepped out and held out his hand for you, gallantly helping you down the step as your eyes adjusted to the moonlit hallway. You followed him as he guided you through the castle back to your dorm, hand in hand this time, and once it was time for you to go your separate ways, he wished you a goodnight with a shy kiss on your lips and a smug grin on his face that you knew all too well.
---------------------------------------
By some kind of miracle you couldn’t quite comprehend, you hadn’t failed your transfiguration exam, even scoring a pretty acceptable number of points on it. You should have been overjoyed when Professor Weasley handed you your copy back, even though she looked at you with a sucpicious expression on her face, but your mind was mulling over something much more important.
By the time your last class of the day was over, you still hadn’t managed to smile a single time, absently doodling on your parchement paper instead of taking notes for the next exam. You only realized that your day was over because all the students around you suddenly got up, leaving you to pack your things up in a rush. You were the last person to leave the classroom but, as you stepped outside in the courtyard, a familiar freckled face was waiting for you by the door, a grin on his face that you tried to imitate, although your heart tightened in your chest and it suddenly felt like there wasn’t enough air outside to fill your lungs.
“So ? Did you pass Weasley’s preparation exam ?” He inquired, excitedly enough to make you think that he already knew the answer. But when he saw how difficult it was for you to feign the same kind of enthusiasm, his face dropped and his brows furrowed intensely.
“I did.” You told him, walking to the fountain so that you could sit on the edge of it, a welcomed rest after the sleepless night you had endured.
“Then why do you look like you’ve seen a boggart ?”
“I’m fine.” You said, but you knew he didn’t believe you at all. You barely believed it yourself.
“What’s going on ?” He asked, his tone softer, concern on his face as he sat down next to you. You took a deep breath, panic rising in you once again. You knew that you would have to tell him eventually, but the fear of how it might ruin your friendship weighted heavily on your chest. “Is it because of… What we did last month ?”
You looked at him, surprised to see his usual confidence gone, replaced by worry and empathy.
“Yes.” You admitted, quietly but he looked away, letting you know that he heard you clearly.
“I’m sorry if I did something that upset you.” He said, his legs nervously bouncing up and down. “I noticed you’ve been distant since it happened, I really didn’t mean to make you uncomfortable…”
“No, it’s not that, I’m not upset.” You said, shaking your head, which seemed to reassure him slightly and he dared look at you again. You knew it was time to tell him the truth and you didn’t know of any better way to do it than dropping it on him like a ticking bomb. “I think I’m pregnant, Sebastian.”
You watched as his eyes widened and many different emotions passed on his face, from confusion to absolute fear.
“Wh-What ? Is it… Mine ?” He asked, once the shock of your confession allowed him to speak again, although his face had turned ghostly pale.
“No, it’s Poppy’s...” You snapped, vexed by his question. Whose else could it be ? He was one of the only males that still dared approach you now that the whole school knew of your ability to wield ancient magic and of the many deaths such a power had caused. “Of course it’s yours !”
“Alright, okay, let’s not panic.” He said, seemingly struggling to follow his own advice, jumping up from his seat to walk around you in circles with his hands tugging at his hair and a grimace on his face. “How did this happen ?”
You raised an eyebrow at him, wondering if you really needed to have a conversation about the birds and the bees with him… But when his brown eyes met yours, something flashed in them, making it clear that he knew exactly how it had happened, the memory still playing in details in his mind on a daily basis.
“Gosh, what are we going to do ?” You whined, hiding your face behind your hands. “My parents are going to kill me… And they are going to kill you too.”
“They don’t need to know now, right ? Nobody has to know yet, there’s still time.”
“If I don’t tell them, they’ll figure it out pretty quickly when I’ll look about ready to pop after we graduate...”
“But by then we’ll have figured things out too… Hopefully.” Sebastian said, with a smile he meant to be reassuring but you could still clearly see the sheer panic in his eyes. “Until then, we should try to keep it a secret... Even from Ominis.”
“Okay, that shouldn’t be too hard.”
