"What are you carrying on about?" Bellatrix laughed dismissively. "Is there any need to be so dramatic?" She rolled her eyes but kept her feet firmly on Lavender's back enjoying using the sexy Gryffindor as a footstool and planning other ways to use her appropriately.
"I can understand that desire and I'm nothing if not fair and I can even be nice," Bellatrix replied. "Though, I can't have you getting me in trouble for being nice to you. So, I'm going to need you to do something." She paused dramatically. "Take out your wand," she instructed.
Bellatrix drew her own in preparation. "Swear on your wand that you won't speak to anyone about anything that happens in detention and I will find you a new punishment," she vowed.
