The friend Rosie left behind didn't even cross her mind as she exited the party with the mysterious boy. It's ironic, she thought to herself, it's my first time at one of these parties and i barely lasted fifteen minutes.

The ice haired boy had his hand on the small of her back, as he led her out and down a corridor. Soon, the sound of the music and teenagers had faded, leaving only a heavy silence between them, and the echoed tapping of their shoes on the cold stone floor.

'Where are we going?' Rosie inquired softly, knotting her hands together.

She didn't look at his face but she could hear the impatience in his voice. 'Not far. I have the perfect place.' Rosie didn't give him a reply, and wondered if this really was the best idea. This was hardly a good way to make friends outside of hufflepuff, which had been her aim. She hoped that this boy would be gentle with her, just as the other hufflepuff boys had been, and above all, she really hoped she wouldn't regret this. Rosie, being open minded, decided to stop overthinking and let what would happen, happen.

'In here.'

His gruff voice snapped her out of her deep thoughts and she realised they were stood outside Snape's potions classroom. Her jaw dropped.

'Merlin's beard, you're joking.' She gasped. 'Snape will feed us to death eaters.'

He put a finger under her chin and lifted her face, planting a slow kiss on her surprised lips to shut her up.

'Not if he doesn't find out.' He whispered onto her mouth.

And with that the discussion was over. She surrendered to him, wrapping her arms around his neck and kissing him back gently, letting this be just another crazy aspect of a crazy night. He pressed her against the locked door, his body pinning her hard. His cold hands untwined her fingers from around his neck and held them above her head against the door, then wedged his hard erection between her legs. Rosie moaned into his mouth, feeling her legs become weak and her groin begin to throb. He left her swollen mouth and began kissing down her neck, nipping aggressively at the tender skin, causing Rosie to arch her back in pleasure.

Suddenly, the boy stepped back, leaving her a panting, flushed mess. He ignored her confusion and placed his hand on the door.

'Lily.' He said, and in obedience, the door to the classroom swung open.

'He keeps it locked with a password, but I've heard him say it before. Must be his favourite flower or something stupid like that.' He sneered, rolling his eyes as they entered the musty classroom. It was dark and there was a heavy smell of old books and burning. Before Rosie could even catch her breath, the boy flung the door shut and slunk slowly towards her. The bang of the door made her flinch, and she realised just how close he was to her. Their hot breaths intertwined,thickening the air between them, as they stared into each others eyes, her head tilted upwards to meet his.

Rosie thought his cold, grey eyes were somewhat beautiful, if not intimidating, and this unnerved her. They didn't even know each others names. It all seemed too personal.

Despite the fact that he had left her craving more outside the room, her heart was now thudding doubtfully. She knew he was the type to do this often, with many different girls, so there would be no awkwardness on his end. But nevertheless, she couldn't help but feel the desire to know him first. In fact, staring into his eyes, with his intense glare looking into her soul...she was afraid of him. She bit her lip in concern and his heavy eyes, almost ink black, trailed down to them.

He felt an animal inside his stomach grow as her brown doe eyes looked up at him innocently... timidly. Why was it that he was turned on by the fear in her eyes? Her breathing was shallow and quick, and she immensely reminded him of a tiny brown bunny rabbit. She was so small and pure that he completely and utterly wanted to destroy her. Looking into her eyes had made him enraged- it was too personal and he didn't like it. He wanted to hear her scream, to run his hands over her naked honey skin and leave possessive bruises all over her- to show everyone how she deserved to be treated. He hated her for her unintentional purity- it angered a deep part of him. There was something different about this girl, and it annoyed him that he couldn't put his finger on it. He didn't recall ever seeing her around the castle. Was she new? Why had he only noticed her tonight? Her slender figure looked so angelic dancing at the party that he had approached her, something he never did. The girls always came to him. Maybe he hated her because his instant attraction to her damaged his pride. Or maybe it was because she was everything he wasn't.

He sometimes wondered if his insatiable desire for sex was worrisome, if he would ever find a girl intriguing for something other than her body, but he highly doubted it. This girl stood before him was beautiful, yes, but the only thing he wanted from her was a fuck, he tried to convince himself. Yes, that's what he needed. To get it out of his system. To fuck her so hard that he could no longer see her as innocent and beautiful anymore. So that she would be ruined for him and he could forget about those sincere brown eyes.

His dark, hungry eyes bore into Rosie's. She could feel his unwavering glare pierce her. uncomfortable, she lowered her eyes to the floor, her thick lashes shielding her from his deep gaze. He smelled like an intoxicating blend of apples, musk and spearmint and it clouded her mind with scandalous thoughts she knew she shouldn't be having. Her stomach clenched with desire.

'Fuck.' He murmured in frustration, and forcefully pulled her waist forward against him, kissing her aggressively. The kiss was raw, passionate desire as their hands began raking all over each other. Rosie wrapped her legs around him and he carried her to a desk, his strong arms slamming her down on it and towering over her with her legs either side of him, lips still locked with their desperate intensity.

He aggressively pulled her panties down, flinging them onto the floor, and his thick fingers sank deeply into her wet, throbbing pussy. Rosie's back arched as she moaned in pleasure, sprawled out on the desk. She had never been treated so roughly...and she liked it. His thumb circled her clit slowly and possessively, whilst still thrusting his fingers inside her, and her whole body shuddered with uncontrollable pleasure. His lips clasped onto her neck, leaving angry bruises all over her.

He couldn't take her eyes of her flushed and writhing body. He felt powerful watching her come undone by his touch, and swore to god he would kill any motherfucker who ever touched her. Nobody would give her pleasure except for him. Her moans were ragged and her pussy was dripping wet for him...and he had never been so turned on.

Impatiently, he threw off his black blazer and unbuttoned his black dress shirt. Rosie sat up to help him zip down his trousers but he grabbed her hand and pushed her back so she was lying down in front of him again. Seconds later, he stood before her, his pale smooth skin illuminated in the dark light. Rosie gave a short inhale of breath. He was unreal. His toned set of abs led down to a prominent v-line. She dared not look down at his dick, which was resting eagerly against his stomach. Instead, her eyes locked onto his, filled with lust.

He stood by the edge of the desk and forced apart her legs again. He quickly pulled her dress up above her head, tossing it carelessly into the corner of the room and unclasped her bra with unsurprising ease. Overcome with lust, he forcefully pounded his dick into her, not caring about her loud whimpers of pain. The animal inside really had taken over.

A veiny hand snaked around her neck, cold rings digging into her tender flesh, that was already covered in large bruises, causing euphoric goosebumps to prickle Rosie's skin. It was hard to separate what was pain and what was pleasure.

He could feel her slick walls tighten around his throbbing member, making him groan hoarsely. His eyes remained locked onto her slender frame, watching it come more and more undone as he pounded into her. Her curly hair was sprawled messily around her rosy face, and from her rosebud mouth spilled a continuous stream of delirious moans. Lifting his cold hand from around her neck, he examined the bruises he had left with satisfaction. Those bruises proved she belonged to him. He needed everyone to see how dirty his little hufflepuff actually was; he wanted to ruin her. He couldn't have her wandering around the halls of hogwarts, radiating her innocence as she must've done before- the thought made him angry.

Once again energised with anger, he slid out of her and moved to sit on the edge of the desk, pulling her onto his lap to sit upright on him Once again, he entered her, forcing himself deeper and clutching her tiny, quivering figure to his chest with his big hands.

Rosie could feel her climax building up inside of her like a volcano ready to explode. She toes curled and she began to see stars, wailing loudly as he kept fucking her harder and harder and harder. His atavistic grunts were hot against the skin of her neck and she could feel he was on the edge too. Rosie arched her back, her head tilted back facing the ceiling as she reached her climax, her whole body shuddering and her screams echoed in the empty classroom. The boy latched his mouth around her nipple, hungrily sucking and swiping his tongue across the sensitive bud.

They were lost in their own world of longing as he came inside her and they became a tangled mess of one being. His thick cum filled her insides and she whimpered into the nape of his neck. His head rolled back, lips parted and he panted raggedly, his whole body dripping in testosterone.

Rosie climbed off his now limp dick, her body feeling tender and sore after his ruthless display of lust. Her legs almost gave way as she stood up, but he made no effort to help support her. He just watched her with dark eyes, his piercing stare half-concealed with blonde hair that had fallen over his eyes. Rosie wondered why he was being so hostile, feeling a stab of self consciousness as she stood naked and shivering before him. She hadn't noticed how cold the potions room was until now. Awkwardness crept in and she hurriedly decided to gather her clothes together. When she looked up, he was gone.

He had quickly put his clothes back on as she was slowly doing the same on the other side of the room and hastily left Snape's classroom. He couldn't bear to look at her after feeling the way he just did. He easily could have fucked her again and again through the night, desperate to see her lust-filled eyes lock with his once more. But he couldn't. He couldn't allow himself to feel this way. What was wrong with him? He usually felt disgusted with the girl after, full well knowing she was just a convenient fuck and nothing more... but she was different. He had wanted so badly to hold her in his arms and cradle her to his chest until she fell asleep, but he knew he could never be that type of man. He thought fucking her would destroy her purity, but as he replayed the sound of her innocent moans in his mind, he felt nothing more than the overwhelming need to protect her. Confusion swirled in his mind. He didn't even know her name.

He stormed down the stairs to the entrance of the slytherin common room in the dungeons. Although it was cold, he felt hot and constricted, as more panicked thoughts kept erupting in his mind. He snarled the password impatiently and marched into the common room. He was so glad to see that everyone was still at the party. Making his way up to his private room, which his father had paid for, he began taking his jacket off, feeling confined in its tight shape.

He slammed the door and threw open a window, taking deep breaths of the cold night air. What was wrong with him? Why was this girl ruining everything? He had never, ever, been affected by someone like she had affected him. He had never felt the warmth she made him feel before...and he didn't know if he was repulsed by it or infatuated. Either way, he needed to get rid of her. He never wanted to feel so out of control again.

Rosie stared, stunned, at the open door. He was gone. She didn't know how to feel. She felt so ashamed, and yet...there was a small part of her that regretted nothing. That same part of her would willingly fuck that boy over and over in every room of the castle. But her shame prevailed. Despite the fact that she wasn't surprised he didn't stay, she felt disappointed. It meant nothing to him, she told herself harshly, so stop thinking about him and get yourself together. She had never felt so many emotions in one night...and although she hated to admit it, she had never orgasmed like that before.

She slowly made her way back to the kitchens and into the hufflepuff common room. She was in no rush to get back to Bella's inquiries and needed time to think.

As Rosie passed a window, she caught her reflection with surprise. Her neck was littered with dozens of dark purple bruises. She gasped, wincing with pain as she traced her fingers on them. She could almost feel his cold rings digging into her neck, or his rough, possessive kisses down her nape once more. She felt a prickle of desire shoot up her spine, but she quickly repressed it. She needed to forget about this boy. He wasn't good for her.

She didn't want to assume anything about him, it wouldn't be fair as they didn't know eachother, but she knew how he made her feel and she didn't like it. He seemed to bring out a primitive side of her. Rosie didn't want sex to be the primary factor of a relationship. She valued loyalty, kindness and honestly above all, and she couldn't see this boy offering her any. Why was she even thinking about a relationship? Rosie scolded herself for being so naive. He probably wasn't even thinking of her.
