Prompt: Y/N Black is a mystery to many. She isn’t interested in making friends, only her studies. However, unbeknownst to many, one boy has piqued her interest——Tom Riddle. Little did she know, he had an obsession with her.
Sidenote: I did use some spells from the vampire diaries just for the heck of it. I may do a part two, but I’m not sure if it really needs it. I’ll leave it up to you guys!
Everyone seemed more chattier than usual. Maybe it was the upcoming Yule Ball or maybe it was because holidays were approaching. However, you hated the buzzing chatter, the obnoxious shouting, and all of the crowded halls. You had tried to go to the library as an escape from this madness, but everyone had infiltrated the library even.
You were the Scrooge that everybody was painfully aware of as you stormed through the halls with your books clutched to your chest. If you were a Hufflepuff, Ravenclaw, or Gryffindor, they would have laughed at the irked expression on your face. However, knowing you were a Slytherin strikes fear in many.
Not to mention you were a mystery to many. You were oh so quiet, along with a freakishly amount of smart, and an unearthly amount of beautiful. You chose to stick to yourself, choosing to not make any friends. You instead chose to have acquaintances in case a group project popped up, however you normally managed to worm your way out of that so you could work alone.
That was how you preferred doing things, alone. Other students have given up on trying to befriend you, seeing it as pointless. Guys would still try and ask you out, but their advances failed. They hadn’t noticed that your interest was piqued by a boy already. However, it seemed that he was just like you.
Tom Riddle was a handsome young man with jet black curly-ish hair and dark brown eyes that looked almost black from afar. He was fairly tall and had a lean look. His face was always blank…passive as he studied or walked through the halls or even when he was with his group of “friends”. They were his followers in his mind, not his friends. To anyone else, they saw them as a happy friend group.
You had noticed the things that anyone would pick up about Tom from afar, like his intelligence. Tom excelled in all of his classes, in fact he was tied at the top of the year with you. He too was introverted, preferring to be alone and in silence. For someone as passive as Tom, you noticed things he did. When he was judging something, he’d lean back in his chair, occasionally quirking an eyebrow as if he was impressed or annoyed.
When he was in a rather intuitive or creative mood, his eyes seemed to be a lighter shade of brown and he would get carried away in his journal. When he was thinking, he would zone out on his journal or something in the room.
You noticed that he’d clench his jaw until a muscle there ticked when he got angered. When he was annoyed, he had a tendency to sigh.
She stood among Tom Riddle and all of his “friends”. Tom’s eyes find you who was clearly irritated. You had made your way through the crowd and head towards her.
“Hey, that is no way to talk to your favorite cousin.” Narcissa scolds.
“Who said you were my favorite?” You ask.
“It’s because it is me.” Bellatrix grins.
“Not you either.” You mutter.
“Moving on, have you seen Sirius or Regulus?” She asks.
“I’m not their keeper, Narcissa.” You mutter.
“They said they were meeting up with you.” She says, sighing in frustration.
“Well they didn’t. I need to get to class.” You mutter.
Before you could go, Bellatrix grabs your upper arm in a tight grip. You turn back to her with a clenched jaw as Narcissa steps back, muttering an “Uh-Oh”.
“Leaving so soon, cousin?” She mocks.
“Bellatrix, I’m warning you now to let go or you will regret it.” You warn calmly.
“What will you do? You're all goody two shoes, yet your in Slytherin. I think that dumb hat sorted you into the wrong house.” She says.
You pull your wand free, pointing it at her as you mutter “Stupefy”. You roll your eyes as she flies backwards through the crowd.
“If I wouldn’t get expelled, I would definitely crucio you or use the killing curse on you for your information. However, nothing is stopping me once we graduate.” You say, before turning and leaving the group stunned.
Tom smiles slightly as he watches you walk away, finding himself even more intrigued with you than he originally was. Call it an interest or maybe an obsession at this point. He liked to watch you when he could. He noticed things about you that he was sure no one else noticed.
He knew you were a quiet and mysterious girl, but underneath that “innocent” mask you wore, he knew there was a strong woman with a dangerous mind. You were far from innocent and today proved that more so to him. To anyone else, you were that innocent girl. However, when you let your guard down if you were stressed or angry or irritated, he could see the danger swirling in your (eye color) eyes.
He lets his smile fall, regaining his composure before turning back to his group. Bellatrix was back on her feet, a scowl on her face as Narcissa helped hold her up. He watches as Sirius and Regulus join them.
“What is wrong with you?” Sirius asks.
“Your bloody sister is what is wrong! She used stupefy on me!” She snaps.
“How pissed off did you make her?” Regulus chuckles, shaking his head.
“You both told me you were meeting with her about becoming a follower. Yet, she hasn’t seen either of you all day. So, where were you both off to?” Narcissa snaps.
“Have you seen how mad she can get? We learned not to mess around when she gets mad, Issa. When she is mad, she will take down anyone in her path. We’ve learned how to avoid making her mad. So, you go have that conversation with her because I rather not get crucio’d again.” Sirius says.
“She may be quiet and keeps to herself, but Y/N is a ticking time-bomb when you make her mad. She is intelligent, and maybe too intelligent for her own good. She also liked being stronger than others in magic, so that is why she studies so hard. However, because she is so antisocial and introverted, even as a child before Hogwarts, she took her studies serious, so she doesn’t understand fun. She is boring.” Sirius says.
“I bet she hasn’t ever shagged anyone, or snogged! A sixth year and a virgin! That is embarrassing.” Bellatrix cackles.
That further piqued Tom’s interest about you.. He found himself having more thoughts about you, both innocent and sinful thoughts. However, his sinful thoughts changed to the exception of you being a virgin. That made him feel a possessiveness over you he wasn’t quite sure how to feel about. However, he knew that the idea of you being with anyone else was sickening to him. You were his, you just didn’t know it yet.
Your studies past fairly quickly and you were heading towards the Great Hall. You sit at your normal spot, Regulus sitting next to you. Tom sat a table down with his “friends”, however his focus was on you. Regulus gently closed your books, pushing them away.
“Eat, then study.” He stresses softly.
As irritated as you were about him taking away your books, you listened. Tom quirked a brow, finding himself wondering if it was often you got so distracted by your studies that you didn’t take care of yourself the best. His eyes roam over you slowly, noticing the dark circles under your eyes along with the thinning face of yours. So, it was often, he thought.
“Y/N! My favorite sister! How has your day been?” Sirius asks as plops down across from you.
“What do you want?” You ask, sighing as you pushed your food around on your plate.
“Nothing to do with studies I hope, she is taking a break to eat.” Regulus stresses.
You close your eyes as the two start to argue, resting your chin on your hand. You open your eyes when Regulus stands, his voice getting louder.
“Enough!” You snap, the two instantly quieting.
It had gotten the attention of those around your table. You take in a slow breath before letting it out, regaining your composure before looking between your brothers with a blank look.
“You two bicker like a bunch of children. This is our brief moment to be able to hang out, however you both don’t know how to push aside your differences because you both are too hot-headed and irrational.” You rant.
You snatch up your books that Regulus had pushed away from you earlier and stood from the table as you left the Great Hall.
Tom watched you leave before looking between your brothers, before his eyes fell on your plate of untouched food. He puts some food in his bag, going unnoticed and decides to leave himself. He made his way to the library, heading to the forbidden section where he assumed you’d be. He feels a brief moment of pride flare in his chest, right about where you had gone. He clears his throat and you look up from your notes.
“Here. I noticed you didn’t eat.” He says.
His voice surprised you. It was deep, soft and mysterious. He pulled out some food he took from the Great Hall and handed it to you.
He nods, going to leave and you begin working on your studies again. You sigh as a loud group comes into the library.
“Would you allow me to show you a place I like to go?” He asks, looking back down at you.
“I don’t see why not.” You admit, gathering your stuff before standing.
You follow behind Tom, not quite sure where he was taking you. You knew of his quest to become the Dark Lord. Some of his followers had big mouths, so you heard more than everyone thought you knew. They assumed you were clueless about his current quest and they all were tip-toeing around who would be the one to break the news to you. However, you knew. You knew more than them in fact.
He looks around, making sure there was no other students or professors in the hall before a door appears in the wall. Your lips part from surprise as he ushers you in, following behind you. You looked around the empty room in awe.
“The Room of Requirements…I’ve heard of it and I’ve looked everywhere for it.” You mumble.
“Yes, I searched for this room for awhile myself. I later learned that the room only will appear in great need.” Tom explains, seeming rather smug about finding it.
“The room seems to know you quite well…and you seem to know the room quite well too. Otherwise, the door wouldn’t have appeared because I’m sure my studies are not in great need.” You say, turning back to him.
You feel a heat spread across your body as you catch his eyes on you. The dark eyes slowly trail over you, mapping out your body. His eyes stop on your blouse where you had a few buttons undone since you were alone and had started to get a little hot in the confined aisles of the forbidden section in the library.
He steps forward, closing the distance between the two of you. You look up, not realizing that he was this tall. He puts a hand out and gently grasps your hip before trailing it up your side. He tugs on the middle of your blouse, revealing more of your cleavage, before he starts undoing the remaining buttons.
“That and maybe because I am in great need of you.” He murmurs, leaning down to trail his lips along your neck.
You shiver, feeling a trail of goosebumps being left behind from the ghost touch. His hands find your shoulders where he pushes the robes off before pushing your blouse off along with it. He leaves a soft kiss on your racing pulse, before he pulls back to look down at you.
You were left in a dark green lace bra, and he tsked quietly, approving the way they made your breasts look. The bra seemed to work as a push-up bra, but really Narcissa had gotten you the wrong size this year.
His eyes trail over your stomach, noting the soft curves he would be sure to feel later. His eyes focus on the short school-girl skirt, also Narcissa’s doing. You didn’t fret much about it as you knew you’d wear your robe more often than not. You were wearing knee high stockings with a pair of mary-janes.
“The school girl skirt, hmph, your just asking to be fucked, aren’t you?” He asks, a smirk slowly spreading across his face.
“Tom.” You say breathlessly.
“Leave the skirt on, but take your panties off.” He orders.
He begins unbuttoning his own shirt, watching you. You were frozen in place before you start to work the panties down. He held a hand out, looking at you expectantly. Your shaky hand places the matching dark green lace panties into his hand.
He balls it up and sticks it in his blazer pocket. You watch as his long, slender fingers work his belt off. Your eyes focused on his veiny hands.
“Hands and knees.” He says.
You slowly drop to your knees, turning over, no longer able to watch his next move. You get on your hands, moving so you are on your elbows. You arch your back down, sticking your ass out more.
Tom licks his lips slowly, swallowing hard as he watches you get into the position. He inhales deeply, watching as you arch your back. He puts a clenched fist to his mouth, lightly biting himself, not quite sure if this was really happening. The skirt hid nothing. He could see the big globes that he found himself really attracted to. He never would have taken himself as an ass man.
His eyes trail further down to see your glistening entrance. He pushes his pants off before he gets on the ground behind you. He brushes your hair over your shoulder, before he finds himself tracing down your spine lightly. You shiver unintentionally, however he enjoyed the effect he on you.
“How bad do you want me?” He murmurs into your ear.
“Please, Tom.” You whisper as you push your hips back.
“Pathetic. Do you want my cock or not?” He asks, grabbing a fistful of your hair and roughly jerking your head back.
A breathless moan fills the thick air in the room as a heat spreads across your scalp. He clenches his jaw, feeling himself twitch from the sound he heard. It was the beginning of a beautiful symphony, one he didn’t realize how much he’d become crazed for.
“Tom! Please! I need you!” You cry, feeling frustrated that he wasn’t touching you where you wanted to be touched.
He smirks, gently grabbing your hips. He uses his other hand to guide himself into your dripping entrance. He groans, your walls immediately grasping onto him, suffocating him. You moan lowly, your hands grasping at the stone floor as your eyes flutter shut.
“Fuck.” He curses, working himself in and out of you slowly.
“Tom, please.” You plead, pushing your hips back.
“Is my cock the first one you’ve ever had?” He asks, his eyes burning in the back of your head as he awaited your response.
“Yes! Please, Tom!” You cry.
He couldn’t help the grin across his face. He heard it, but he wasn’t sure if maybe you just kept them out of the loop. But, knowing he was the one to take your virginity was exhilirating to him.
“I better be the only cock you have here. You are mine.” He warns.
“Yes! I-I’m yours, Tom!” You moan as he starts to move at a faster pace.
“I’ll kill any boy who dares to be with you, because you are mine! I’ll punish you if I see you talking to some boy.” He growls, his hips now savagely moving.
You cry for more, your soft and loud moans were music to his ears. He breathed heavily along with you as held onto your hips tightly. Skin smacking echoed in the room and you heard his soft groan which sent you coming. He groans louder as you clench around him, coming around him.
You stood on shaky legs, buttoning up your blouse and grimacing as you feel your shared climaxes slowly leaking out of you. He grasps your chin, looking at you with a stern look.
“Keep it in. I want you to know who fucked you.” He says.
“Tom, I need my panties.” You say as your cheeks flush.
“Find another way to keep it in.” He says, before focusing back on straightening himself out.
You pull your blazer on along with your robes before grabbing your books and hurrying out. You reach the Slytherin common room, Narcissa and Bellatrix looking up from their game of cards. Sirius and Regulus’s backs were to you.
“Oh my god, you got shagged!” Narcissa exclaims with a grin.
“Who was it?” Bellatrix asks.
“Yeah, I’d like to know.” Sirius seethes, taking in your disheveled hair and the hickeys on your neck.
Narcissa looks at your knees to see that they were scraped up, but you choose to ignore your brothers and cousins as you make your way past them. Regulus laughs, yelling “Atta girl!”
A small smile graces your lips at your little brothers comment. He too was protective of you, but he knew you inside and out. He and you were far closer than you were with Sirius. You get to your dorm and think of showering, but then your mind wanders to Tom. Keep it in…
You pull on a pair of fresh panties as you change into your nightware. You found yourself tossing and turning for a long while before you fell asleep. By the time it was time to wake up, you were exhausted. You could sleep in, but that ruins your morning routine.
You go to the shower, grimacing at the burn in your stomach. It was now that you realized you didn’t eat once yesterday. You finished up in the bathroom before pulling on a black lingerie set. You gasp as your door opens and Tom walks in.
“I knew you’d be awake.” He says, his eyes slowly roaming over you and some of the bruises he had made from where he held you still.
“Tom, what are you doing here?” You ask, grabbing a random robe and pulling it on.
“I’ve seen it all, darling. I wanted to tell you no more skirts.” He says and you look at him confused.
“I…Is it because how short they are?” You ask.
“That and the school girl skirt should be meant for my eyes when we are alone. Do you understand?” He asks.
“I…yes, Tom.” You say quietly.
He grins, looking at your neck where you had several hickeys before he leaves. You frown and look at the outfit you had prepared for this morning. It consisted of a school girl skirt.You sigh, grabbing a dark green skater skirt that ended a little about mid-thigh. There wasn’t much you could do about the length of your skirts until you went shopping again.
You grab your button up blouse and your Slytherin tie. You grab the blazer and sigh when you see dust on it. You hang it back up, deciding you will have to clean it later because you don’t have time now.
You pull on your knee socks and mary-janes when there was a knock at your dorm door. You open it and see it was Narcissa.
“I came bearing gifts.” She says.
You open the door and she guides you to the small vanity as she begins to help you cover the hickeys on your neck and jawline.
“So, who was it?” She asks.
“I’m not sure if I’m ready to say who it was yet.” You murmur.
“Did he force you? I’ll make him suffer the worst ways imaginable.” She says seriously.
“No, no, he didn’t force me. I’m just not sure what is happening yet. I don’t know if it merely was just another shag to him or if it’ll turn into something. However, he’s being a little controlling of what I wear, mainly my skirts.” You explain.
“I feel like I already know who this is.” She says, sighing.
“Oh…how did you know?” You ask.
“Tom is…many things. I don’t know if he is capable of love and a relationship. He is a very possessive man. And I mean to the extent that it isn't healthy. He is ill-tempered and easily jealous. Not to mention he can be obsessive too. I personally think you should put some distance between the two of you and let things die down. I don’t know what his intentions are, but I’m sure they aren’t good.” She explains.
“Alright.” You say quietly.
You were quite sure how to feel. But, you knew Narcissa meant well and you also knew that she knew Tom better than you. You trusted her advice almost as you trusted Regulus’s.
“Thank you, Issa.” You murmur and she nods.
She leaves you to your thoughts and you realize you need to head down to the Great Hall for breakfast. You gather your books and make your way out of your dorm in a daze. You head to the Great Hall and see everyone was already there. You ignore the burning stare that you knew belonged to Tom Riddle.
“Hey, you okay? You seem out of it? And your running late.” Regulus says.
“Oh, I’m fine. I think I’m just in need of food. I realized I didn’t eat once yesterday.” You explain.
“Y/N/N, you’ve got to take better care of yourself. I will start treating you like I did the first year.” He warns.
“I know, I know, and I promise I’ll do better.” You sigh.
“Why is Riddle staring at you? He seems pissed.” He whispers.
“Oh, who knows.” You sigh, briefly glancing at Tom.
Tom was staring at your neck where your hickeys would be, but thanks to Narcissa, they were no longer there. You managed to eat some of your food before it began to make you feel sick. You felt suffocated with Tom glaring daggers into you and Sirius was no better.
“Stop it.” Regulus warns Sirius.
“I want to know who it was.” He snaps, looking back at you.
You clench your jaw, narrowing your eyes at him as you take a slow breath in and let it out. You pull your wand out and keep your hand rested on the table, so you don’t draw anymore attention to you.
“Keep glaring, brother and watch how fast you end up in the hospital wing.” You warn lowly.
“Who is he?” He growls lowly, leaning closer to you.
“Oh shit. Take cover!” Regulus says, going under the table.
You reach forward, grabbing Sirius’s tie and pull him closer as your face heats from anger.
“Astronomy tower, now.” You grit out.
He stands and storms out and you stand as Regulus pokes his head out.
“Don’t kill him please.” He pleads.
You storm out of the Great Hall, wand in hand as you make your way towards the Astronomy tower to see him already there and waiting.
“Who is it!?” He snaps as you both circle each other.
“Sirius, it’s none of your business. Stop trying to act like the older and protective brother. Stop acting like you care!” You snap.
“I do care! You're my sister.” He snaps.
“Guys. Let’s try to keep calm.” Narcissa says as she walks in with her group.
“Yeah, let’s just hug it out and make up.” Regulus says.
“I want to know who has my sister acting like a tramp.” He snaps.
“Oh no….oh no! Oh no! Back up, back up, back up!” Regulus says as he pushes everyone back.
“Bombarda!” You fast and Sirius curses as he tries to dodge the mini explosion you casted his way.
“Confundo!” He shouts, but you dodge it.
“Everte Statum.” You cast, watching as he flies back against the wall, his wand falling in the process.
You walk forward, grabbing his wand before looking down at him.
“Impulsa Animositas!” You snap, gaining confused looks from around the room.
“I…Y/N, have you been creating spells again?” Regulus asks cautiously.
“Again?” Narcissa asks alarmed.
“What did you do to me?” Sirius snaps.
“Say something mean. To any of us.” You say, smirking.
“What the hell did you do to me you crazy bi—ow!” He exclaims after feeling a jolt of electricity go through you.
“Just as I assumed. This spell will zap you everytime you try and say something mean.” You say.
“That’s child’s play you idiot!” He snaps before groaning.
“Hm. This isn’t. Lihednat Dolchitni.” You cast.
His hands find his throat as he try’s to breath. You clench your fist tighter, watching how he struggles more before you wave your hand and it stops. He leans forward, breathing heavily.
“Tread carefully, brother. I have far more up my sleeve than you wish to believe.” You spat.
“You…you will get in so much trouble for creating spells. Regulus and I told you that you need to stop.” He breathes heavily.
“Then keep your mouths shut otherwise I’ll make you suffer in the worst unimaginable ways.” You say.
With that, you turn and walk past the group who seemed shocked. You head back to the Great Hall, gathering your items before heading back to your dorm. You were too upset and riled up to do anything. So, instead you hurry to your dorm and lock the door.
You pace frantically, running your hands through your hair. You let a breath out that you hadn’t noticed you were holding.
“You’re okay. You’re okay. Everything is okay.” You mumble to yourself.
The lock on your door clicks, so you turn and see Tom. He closes the door back and turns to you with that normal passive and cold look.
“That was…impressive.” He says.
“Tom, I really rather be alone right now.” You mutter.
“Why cover the marks I left? I left them for a reason.” He says, his voice hardening as his eyes turn several shades darker.
“I didn’t want to walk around with them showing. People would have said something and I don’t want to deal with that. Plus, I rather the school not know I was your play thing.” You mutter harshly, turning your back to him.
“Who said you were a play thing because I don’t recall ever telling you that?” He snaps.
“Tell me this, Tom. Are you one for commitment? Would you be in an exclusive relationship? Huh, tell me that!” You snap harshly as you turn to face him again.
“I can do commitment. Before, I’d say no. However, for you I am willing to do it. I’m willing to be in an exclusive relationship as you call it. Because I can’t ever get you out of my head! You are all I can focus on! It’s so…so irritating, yet I love it at the same time.” He growls.
“Tom, there are going to have to be some rules set in place if we are to do something. Like the skirt thing this morning. I only wear skirts.” You say.
“Fine. Wear your skirts, well not the school girl ones, however I can’t promise that some asshole won’t end up dead for looking. You are mine.” He snaps.
“Okay, and what about the marks?” You ask.
“You shouldn’t care what anyone says. You never have before, so why care now? I want people to know that you belong to me. I want the guys to realize that you aren’t a possibility anymore. You are mine.” He says, closing the distance between you both.
You look up as his hand wraps around your throat. He tightens his hand and you let a shaky breath out as you clench your thighs.
“You barely know me.” You mumble.
“I know more than you think, darling. You piqued my interest. When that happens, I tend to learn everything I can.” He murmurs, brushing his nose against yours before kissing you softly.
You hum, moving your hands to his hair. You whine when he pulls back, a smirk on his lips.
“What does that mean? How have you learned about me if you just started speaking to me yesterday?” You ask.
“Because I might be a bit obsessive when it comes to learning of the things that interest me. I won’t stop until I know everything.” He says.
There was banging on your dorm door and you sigh, going to walk past Tom, but he loops an arm around your waist.
“Who is it?” Tom asks, annoyed.
“It’s Bella, me and Regulus. Is Y/N in there?” Narcissa says.
“Well go away. I’m about to fuck my girl.” He snaps.
Your face heats up as you cover your mouth to hide your gasp. Narcissa gasps, Regulus laughs and yells for you to get it while Bellatrix throws a fit.
“We are not doing anything! We are just talking!” You exclaim.
“Talking, huh?” He says, quirking a brow at you as he slips a hand beneath your skirt.
You let a shaky breath out as he trails his hand up your thigh. He gets to your underwear, sliding two fingers beneath the lacy fabric.
“Talking and yet you're so wet for me. Do you want my cock again?” He asks, sliding a finger in you.
Your eyes flutter close and he grins widely, loving the way you reacted to his touch. You were the violin and he was the violinist. He played you so gracefully and loved the beautiful symphony that came from your mouth. It was his greatest obsession.
