Letting Lavender go a head and touch herself while she sat in Fleur's lap, Fleur let her fingers idly run over the girl's thighs while she watched. When Lavender's gaze met her's and she spoke, Fleur grinned back at Lavender knowing that the girl could see her eyes, "Non, I suppose zhere not. But zhen, I do not zhink zhat students are suppose to enjoy receiving one eizher."
As Lavender sat on the desk, Fleur could tell that the girl's arousal would stain her blotter. She grinned, knowing that now whenever she saw it, she would have a reminder of what they had just done. There was absolutely no way she was going to buy another blotter, if any asked, she could say she spilled a drink.
Watching Lavender, Fleur leaned back in her chair and rested her elbows on the arms while her fingers were laced and hands in her lap, looking like a very serious professor about to lecture a student. But her dark eyes gave away that she was thoroughly enjoying the show Lavender was putting on and crossed her legs as she watched with a faint smirk on her face.
