Lucy had missed Katie over the break as well. She was spending it with her father's side of the family in Italy, but was planning on taking a small trip back to England to see Katie when the girl had to cancel. Of course, Lucy understood that Katie needed to be with her family, but it didn't change the fact that she still missed the girl.
Sitting in the History class that they shared in her uniform skirt, tube socks with blue stripes at the top an a tight school sweater over her blouse and tie with her usual eclectic bracelets and necklace and hair pinned back with a cute barette, Lucy concocted a slight plan of teasing Katie to help pass the time. Even Ravenclaws got bored in Binns class.
Looking at Katie, Lucy made sure to give her just the seductive, submissive look that Katie had told her that she loved. Adding that with her unintentional habits of chewing her quill and twirling her hair, she knew from Katie's reactions that it was working.
