It all started a month before, at the Yule ball.

Pansy just wanted a one night stand with Draco, but she knew he would never do it willingly.

Sure, they'd been dating forever, but she knew he didn't really like her.

She was pretty, smart, and only a little bit annoying.

She was also a pureblood. That's the only reason Draco was dating her.

Well, she was going to have to give him a little help to get what she wanted.

She had been working on the One-night Lust potion for weeks and the Yule ball was coming up.

I'll just slip some in the punch and then everyone will have a better night. This school could you a little shaking up Pansy thought.

Later that night,

Pansy was wearing a form fitting deep emerald dress that simmered under the lights of the great hall.

Draco looked dashing in a classic black tuxedo that made his grey eyes pop.

She was sure that they were the best looking couple there.

Her hair was in an elaborate mess of curls and pins and her make-up had been done by one of the best make-up artist in the Wizarding World.

However, she had a black shawl over her dress, just so that she could slip the potion in without being seen.

"Draco, sweetie. I'm thirsty. I'm going to get some punch. Do you want some?" She asked in a sickly sweet voice batting her eyelashes at him the whole time.

"Uhh, what?" Draco said distractedly, "Sure, whatever you want, Pansy."

"Ok, I'll be right back." She kissed him on the cheek and walked away.

She poured herself a glass before she put the potion in.

Sneakily, she slipped the bottle out from under her shawl and she poured some into the punch.

Enough that nobody will remember this night, except me, that is, she thought.

She was laughing to herself when Hermione Granger walked by.

"Hello, Perkinson." Hermione said in a stiff formal tone.

"Oh, hello, Granger. Want some punch?" Pansy offered sweetly.

"Oh, uh, sure." Hermione was caught off guard by Pansy's sudden nice behavior. "I came to get some for Viktor too."

"Oho! You're the one who Viktor Krum asked? How special. Maybe you'll get lucky tonight." Pansy winked and walked briskly away from a flabbergasted Hermione.

She sure should be getting lucky tonight. I am.

A/N: Hey, guys. This is short cause it's just a prologue type thing. I got this story idea from Timeturneruser. Let me know if you like it. If you do, I'll keep going. ;) Like it? Hate it? Review it!
