Parvati Patil and Lavender Brown

Harry saw Parvati Patil and Lavender Brown. Lavender had her arm hooked around Parvati's and was dishing about the latest gossip while Parvati looked bored and exasperated. As they passed Harry, Parvati smiled then rolled her eyes.

After they passed, Harry thought. "Parvati's hair has grown to her thighs and she wears it in a tight ponytail."

Parvati's hair changed to match that of Harry's description.

"Parvati Patil and Lavender Brown and bisexual nymphomaniacs and Patil is Lavender's mistress. Parvati leads Lavender around on a leash, and Lavender crawls after her."

All of this became true, and Lavender was on her hands and knees, a collar around her neck, and leash attached to the collar.

"No one at Hogwarts cares about that arrangement as no one has any respect for Lavender. Parvati loves being fucked multiple times a day and always has Lavender use her mouth to clean her and her lovers up afterwards. This behavior is accepted at Hogwarts. Parvati makes Lavender keep Lavender's wand up her arse."

Lavender's skirt poked out as her wand was now up her anus.

Parvati turned back and looked at Harry. She smiled then licked her lips.
