Fleur watched as Lavender squirmed, the sight bringing a smile to her lips. It turned Fleur on, to know that Lavender was at her complete mercy.
Hearing that Lavender was ready, Fleur nodded, and took the quill, but didn't write on Lavender just yet. Instead, she took the feather quill and teased Lavender's skin, just as she had done to Fleur's thighs under the desk. SHe drew the feather lightly up Lavender's stomach, to between her breast, then moving to circle each nipple before tickling her neck, watching LAvender's reactions intently. She didn't speak, knowing that that added to Lavender's inability to see would probably drive her even crazier.
When she had had enough of using the feather, FLeur opened the bottle of ink and gently dipped the quill in, pondering for a moment before deciding on what to write. Deciding to keep it simple for the moment, she merely wrote her name, her elegant signature like her writing her name to claim ownership across the skin right above Lavender's navel and waited for the girl's reaction.
