Open his Mouth

Standing there, Pansy smirked at Harry before letting him in on a secret, “Say Potter, did you know that with the combination of the Sissyficstion Potion and you being my House-elf gives me more control over you then they would alone.”

“In fact, from now on your favorite drink is warm Butterbeer, and you’ll want to have a taste as often as possible. Ah, I see that look on your face Potter.”

Harry tried to hide the disbelieving look that that order could be anyway interpreted as bad.

However it was to late and Pansy noticed, “Don’t worry, that was just the first part.”

Moving her hands to grab the sides of her skirt, she ordered Harry, “Open your mouth as wide as possible without hurting yourself, and keep it open.”

Kneeling with his mouth open in front of Pansy, Harry’s eyes were wide with fear of what she might have planned for him.

Lifting her hands and then her skirt, Harry saw that not only did Pansy’s socks end mid thigh, but she was also not wearing any panties which gave him a view of her hairless cunt.

Shuffling forward and lowering herself until her pussy was covered by Harry’s mouth, she looked down at his eyes and told him, “From now on my piss tastes like warm Butterbeer.”

Pansy relished in the pained understanding that flashed across Harry’s face, that he’d look forward to drinking her piss because it would taste like his favorite drink, something he’d be forever to want as often as possible.

“Drink all of my piss, don’t spill a drop,” she warned him, “you won’t like the consequences.”

Releasing a sigh from the pressure of holding in her piss, Pansy’s eyes lit up with glee watching Harry face flash with yearning for her pee and disgust for the fact that he was craving the liquid.

As the stream of urine trickled off, Pansy told Harry, “Clean up my pussy with your tongue, no use wasting toilet paper,” she finished with a laugh.

Humming from the feeling of her sissy slut cleaning her pussy with his tongue Pansy closed her eyes to enjoy the experience.

When she felt she was sufficiently clean, she opened her eyes and commanded her House-elf, “Alright, that’s enough,” before stepping back and checking his face to see if he missed any drops.

Chuckling when she noticed Harry drank every drop, she told him condescendingly, “Congratulations, you get an O+ for managing to drink all of my piss,” Pansy snickered.

Stepping into a pair of green panties she pulled from her pocket, Pansy said in a bored tone, “Use your House-elf magic to shrink and take your uniform trunk with you. You're to change and wash your uniform every day. Expect a call after later tonight.”

Moving to the door, Pansy unlocked it and stepped out before waving and closing it behind her.
