Lucy Lauren "Favourite Student"

Lucy has given you detention, she can't have you behaving so badly in her college classroom or people would figure out you are her favourite student. She gives you a piece of paper out of her bag and accidentally hands you her knickers, she is embarrassed and tells you that she is going on a date and she was going to change her knickers in case she got lucky. She begs you to keep it to yourself and you agree to but on one condition, she has to put them on for you.
