Your professor was in the midst of yet another one on one tutoring session with you.

when she caught a scent of something. The aroma awoke something primal in her, making her blood boil. Her lips trembled slightly when her gaze met yours. Her eyes were lustful and her fingers were tight around her pen. Was it the scent of your perfume? She saw your lip was redder than usual... your lip was bleeding as was your habit. She couldn't take her gaze away from your bloodied lip.. she needed a taste.
