Disclaimer - I don't own Harry Potter.

Title aside, I also don't own 'Basic Instinct' although the movie inspired this short story. My thanks to White Angel of Auralon for the idea of draining Horcruxes.

Enjoy and please let me know what you think.

Basic Instinct.

The teenage girl moved sensuously through the man's flat, her long, beautiful and rich dark red hair curling beautifully like woven ruby down her back, while the man himself allowed close behind her, his eyes running up and down while he wore a lecherous smirk on his face as he watched her delectable bubble butt swinging from side to side as it was wrapped up in her tight party dress.

Once he was inside the flat with the girl in front of him, the man couldn't believe how lucky he was to have picked up this gorgeous girl. His trousers were straining as his erection grew harder and harder, much to his surprise since he had never felt any erection of his grow this big before. He was dying to fuck this girl. The fact he didn't even know her name didn't matter one little bit to him. All he wanted was to have fun with her.

The girl turned to face him. She's one hot piece of arse, the man thought to himself as he studied her once more. She had a rather willowy frame, with long statuesque legs which looked like marble pillars connected to dainty looking feet which were currently encased in a pair of high heels. She had a figure most models would kill for, only her figure looked like it was natural rather than forced, which only added to the attraction he felt for her. She had two large looking tits, not too big but not too small, and her face was flawless with the dainty nose and plump red lips slathered with red lipstick. Her eyes were two large gleaming and lovely emeralds, and right now they were shining with lust.

The moment he had closed the door, the girl looked around for a moment before she turned to face him. "Nice place," she remarked, her voice a soprano voice that oozed sex.

The man smiled at her, trying hard to keep how this teenager was affecting him.

But the girl's next action took him by surprise. She cast her eyes down and smirked as she locked eyes on his groin, a smirk growing on her face before she lifted her eyes. "Someone's happy to see me," she remarked coyly.

The man gaped at her, surprised by her bluntness. She giggled and she walked over to him. His nose twitched as she approached, and her sweet perfume and scent wafted up his nose and through his nostrils, and he gasped, wondering if he was becoming harder just smelling the girl. He jerked in surprise when he felt a hand which was much smaller and daintier than his hand grip his cock through his trousers.

"Hold on, a bit sudden isn't it?" he protested, although it wasn't a particularly forceful protest given how the girl was slowly jacking him off.

The girl smirked. "You're the one with the erect cock," she purred.

She leaned in. "Do you wanna fuck me?" she asked. "Your cock is up, I've caught you looking at me and my hot body. But do you want to fuck my pussy?" she whispered.

The man was breathing in and out desperately. He had never encountered a girl who had come onto him in this manner before now, and his brain seemed to have stopped.

"Answer me," she said, stroking his cock.

"Yes, I want to fuck your pussy!" he cried as more shivers of pleasure went through his body.

"Take me to your bedroom, and then we can fuck!" the girl demanded.

The man growled and he grabbed her hand and yanked her off of her feet, and pulled her into the bedroom. Once inside, the girl shoved him onto the bed before she started gyrating her body much like a stripper. She ran her hands down her body before she turned around and slowly unzipped her dress, and she pushed it off down to her ankles, revealing the sexy red silk bra and panties she was wearing as well as the dark stockings she had been wearing the entire night.

The girl turned her head around and smirked at him. "Well, aren't you going to get undressed?" she giggled.

The man jumped up and instantly started to undress, although he had problems with his trousers and boxers because of how hard his erection was, he managed to shimmy out of them, although he did have problems with the shoes.

The moment he was naked, his cock standing proudly to attention, the man stared at the girl and he ran his eyes down her body, seeing her milk pale skin and the sexy long legs she had, and he felt himself grow hard as he looked at her bubble butt. He wondered what kind of treasures she was hiding on the other side.

The girl grinned and she turned around, revealing her large tits which were round and smooth and so full they existed him at once. Every inch of the girl was sexy. She smiled as she stepped towards him and she leaned in and kissed him deeply on the lips, and he started kissing back, feeling the plump lips under his own, and he tasted her lipstick. As they kissed, he moaned with surprised pleasure when he felt her soft hand on his cock again, although this time he could feel her fingernails gently grazing the skin, which did incredible things to him that he had never felt before, from any of the girls he'd had sex within the past.

The girl pulled back just as she was pushing her nipples into his chest. She smiled and she gently lowered herself down on her knees, her hand was still on his cock. He gasped when he felt her warm tongue slither out of her mouth, and she started to slowly lick his cock. The man threw his head back and gasped as she started to slowly open her mouth, her teeth softly grazing the foreskin. Once she had his cock in her mouth, she began bobbing her head up and down along his length.

He felt himself beginning to cum, but she pulled away and she quickly got onto the bed and pushed herself up the length of the bed on her back before she opened her legs, revealing her sopping wet cunt.

"Fuck me," she said simply.

The man was more than happy to oblige, he quickly clambered on top of the teenager and he shoved his cock into her pussy. He gasped at her tightness; she wasn't a virgin, but she was super tight.

The girl moaned in pleasure as he began thrusting in and out of her hot cunt.

"You're a fucking slut, aren't you?" he asked between pants.

"Of course!" she grinned up at him, before she moaned loudly, her eyes fluttering between being open and closed, revelling in the sensations she was getting. The man grinned down at her, and he reached down and cupped the girl's tits, tweaking her nipples, making her moan out loudly like a whore while he kept fucking her.

He groaned when she began using her cunt muscles to squeeze his cock, and he latched onto her neck and started biting her. She moaned with mewling pleasure as he bit her neck while she squeezed him with her cunt, and she mentally laughed when he groaned as her pussy squeezed him.

XXX

She was on top of him, riding him while her pussy squeezed his length. They had been fucking like rabid animals for the last few hours, and more than once he had come inside her. As he thrust in and out of her, she felt him about to come inside of her. She leaned back and supported herself on his legs before she lifted a hand and flicked her wrist, and a large ice pick appeared in her hand.

She slashed his neck in a flash of silver, spraying arterial blood everywhere. She smirked as some of the blood fell was sprayed on her tits, but she continued to hump her victim.
