Diclaimer: I own nothing.

Their clothes changed to their first set of clothes and music started. But this time they just danced. Not that was any better. They were dancing inmately.

Wasn't in the mood for dancin', forget about romancing
'cause I already got a lady
Wasn't tryin' to be flirty, wasn't feeling dirty
'til this shorty started runnin' on me
With her itty-bitty waist and her pretty pretty face
And the leanest, meanest, badest, badest body
Didn't have no time to waste, she was looking for a test
And she was wanting me to party

Harry pulled Luna on The Minister's table while Theo took the Head Auror's table.

Oh, it's so crazy, she's like Baby, I'm like Swayze
I'm said, oh, and I'm burning up
So, let's turn it up, I said turn it up now

Susan pushed Theo down on chair next to the Head Auror and gave him an lap dance. Harry felt Luna's arse agenst his cock and moaned.

She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me

Theo pulled Susan into his lap and started to kiss her neck making her moan.

Now, I ain't looking for no drama,
I don't want karma 'cause my baby sittin' in bed at home
She knows that I be lying and that I be trying to get this shorty with me all alone
Pretty pretty lips and her big 'ol hips
It's getting hotter when she touches me with her fingertips
And her sexy eyes and those big 'ol thighs
It's getting hotter like The Block up in the summertime

Harry turned Luna around and pulled her in a kiss. He licked her lower lip and Luna let him in. Harry's hands went down to her arse.

Oh, it's so crazy, she's like Baby, I'm like Swayze
I'm said, oh, and I'm burning up
So, let's turn it up, I said turn it up now

Susan pulled Theo up from the chaor and they started to dance again.

She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me

Harry and Luna had switched tables to the Headmaster's table and dancing closely.

Now, I know that my girl is alone
And she's been blowing me up on my phone
But I can shower when I get back home
'cause tonight I'm dancing dirty, yeah..

Susen felt herself beeing pushed agenst a table while kissing Theo hungerly. She moaned as Theo's hands went along her stomach and started to push up her dress.

Now, I know that my girl is alone
And she's been blowing me up on my phone
But I can shower when I get back home
'cause tonight I'm dancing dirty, yeah..

Harry pressed Luna agenst the table while kissing her neck. Luna moaned as his hands went under her shirt and started to play with her nipples.

Oh, it's so crazy, she's like Baby, I'm like Swayze
I'm said, oh, and I'm burning up
So, let's turn it up, I said turn it up now

The twins saw how things started to go way wrong and started to stop the spell.

She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me

Snape saw what the twins were doing and went to pull the teens apart and waved to the other teachers to do the same.

She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing, dirty dancing on me
She's dirty dirty dancing, dirty dancing on me

Just as the song stopped the spell wore of and the guys flew of the girls shocking everyone as they saw the look of horror on their faces.

"WHAT THE FUCK?" Susan asked angrly. All four turned to the guilty looking twins.

"Sorry?" They said and everyone now understood that this was suppose to be a prank but it went wrong.

"What did you do?" Harry asked them in a deadly calm voice.

"W-we...um..you see we...um."

"Yes?" He asked and narrowed his eyes making the twins flinch.

"Wegayusohoasipi."

"Care to repeat that?" Harry hissed.

"We gave you a horny potion and a singing pill. Our new products." Harry sighed and pulled Luna of the table. Theo checked that Susan was okay.

"I hope you're happy." With that the four left the hall.

Profferssor Macgonagall glared at them.

".now!" She hissed and the twins ran out of the hall to do as she said.

The twins got detention for the rest of the term with Snape who had them cleaning everything he could think off. He would create a mess just for them to clean up.

Susan and Theo had talked and agreed that it all were because of the twins and went seperate ways but became distant friends. Harry and Luna had secretly dated for a year so nothing between them changed. But no one could ever forget that evening. As soon as they saw one of the four their thoughts brought to that evening. Everytime they heard one of the songs the same thing happened. Hermione did the only thing she could think of. She wrote a book about it and sold it in the muggle world like a fantasy novell. Ron didn't know what to do so he asked one of the aurors to oblievte him. Ginny ignored it as mush as she could. Draco looked at Susan with dared she touch him? Theo was his. (He didn't care that it was because a potion.) Pansy just locked herself in to her boyfriend's, Blaise, dorm room to have awsome sex. The rest of the world? Well who cares?

A/N: Hope you liked it.
