A/N: First of all, you may have concerns, but this is NOT smut. I can neither read nor write that. Characters will mention stuff, but never in detail, nor will you ever have to read detailed scenes of that type whatsoever. Just thought you should know, so you don't get the wrong idea and stop reading. :)

This fic is based off of a (fabulous) movie called Cruel Intentions, as well as the historical fiction movie (Dangerous Liasons, which I named my story after) and finally, the original French book, Les Liasons Dangereuses, which it's ALL based off of. I highly recommend them all! But here's my geeky Harry Potter twist on it. Enjoy!

I. The Challenge

Pansy Parkinson was sprawled across a suede green loveseat, doing not much more than inspecting her manicure, when she came to the painful realization that she was incredibly, gut-wrenchingly bored.

Frowning, she sat up. The queen of Slytherin, the pureblood princess, the fittest and most popular girl at Hogwarts…bored? She was not accustomed to this.

She was also bloody horny.

'Crabbe,' she whined lazily to the stout boy across the room. 'Where's Blaise?'

'Zabini?' Crabbe shrugged. 'Dunno, probably with some girl or another.'

'If you're looking for a fuck buddy, though, Pans…' Goyle grinned cheekily next to him.

Pansy smirked. 'In your dreams, git.' She hopped off the couch and scanned the room. 'Where's Draco?'

'Hiya, sis,' Draco called from across the room, having just entered the common dungeons. He cocked an eyebrow tauntingly. 'Looking for me?'

Pansy and Draco had dated on-and-off until the previous year, when it had been discovered that Narcissa Malfoy had had an affair with Pansy's widowed father. When the Malfoys had divorced and Thomas and Narcissa were married, Draco and Pansy had become step-siblings, which promptly ended their relationship. Not, however, their mutual attraction, although Pansy now refused to sleep with him. She still flirted shamelessly with Draco, despite her current boyfriend Theodore Nott, who was really just her father's choice. He was from a 'respectable, pureblood, wizarding family,' not to mention not being her step-brother, and was one of the only boys her father found acceptable for her to date. Pansy didn't mind it that much; he was a decent kisser (and even better at other things). He was also clueless about almost everything, so Pansy was free to pursue her other conquests, namely the previously mentioned Blaise Zabini.

'I'm bored,' Pansy purred, slyly approaching her step-brother. 'Entertain me,' she ordered with a bat of her eyelashes, flirtatiously pulling on his tie.

Draco rolled his eyes and pushed her away. 'What, so you can tell me how bad I am?'

Pansy giggled. 'Is that what you thought I wanted? Wishful thinking, maybe?'

Draco sighed and shoved a copy of the Daily Prophet at her. 'Take a look at this, then.'

'Since when do I find reading entertaining?' Pansy raised her eyebrows at him.

'You'll find this one entertaining.'

With a sigh, Pansy took the paper, which was opened about halfway through. The article featured a beaming picture of Little Miss Perfect Ginny Weasley, and her Equally Mister Perfect Boyfriend, none other than Harry Potter.

The piece, entitled Why I'm Waiting, was written by the Weaselette herself, detailing her choice to remain abstinent until marriage, and why she had made that choice, how Potter respected her decision, and lastly, a plea to all other wizarding teens to follow her example and consider abstinence. It was so dreadfully... Muggle. Not to mention boring.

Pansy was wide-eyed by the time she finished. 'You're fucking kidding me. Isn't that sweet. The one girl Draco Malfoy will never get into bed,' she laughed.

'What?' Draco scoffed, folding the paper and tucking it into his robe. 'Of course I could. I could get any girl in Hogwarts to sleep with me.

'The Weaselette?' Pansy challenged. 'I'd like to see you try.' She pulled Draco by the hand and sat him on the couch beside her.

'Of course,' Draco assured her. 'If I wanted to.'

Pansy ran her fingers through Draco's hair thoughtfully, then quickly glanced around the room to make sure they were alone. 'What if,' she began pensively, after being assured that Crabbe, Goyle, and any other stragglers had gone, 'I dared you to deflower Potter's princess? What if I bet you couldn't do it?'

Draco paled. 'What?'

Pansy cackled. 'That shouldn't be a challenge, brother dearest,' she began, walking her fingers up and down his shirt. 'After all, you're blindingly attractive, devilishly charming, frighteningly cunning, and, as you put it, could get any girl in Hogwarts to sleep with you.'

'True,' Draco conceded with a smirk.

'If you can't, though,' Pansy grinned mischievously, 'I get your new Firebolt.'

Draco was about to protest, but his pride got the better of him. 'And what would be my incentive?' he asked skeptically.

'You mean the sex part isn't enough?' Pansy laughed.

'With the Weaselette?'

'Hey, she's fit!' Pansy protested.

Draco rolled his eyes. 'I'm waiting for my end of the bargain.'

'Fine, fine. I'll give you what you really want,' Pansy said lightly, licking her lips. 'What you've wanted ever since our parents were married.'

'Erm?' Draco managed.

Pansy grinned seductively. 'I'll fuck your brains out.'

A/N: Hahahah. Oh my. I have a feeling this will be fun to write. Please review! xD
