A group of girls help a guy study by quizzing him on a subject, and every time he gets a question correct for a subject, he gets to tie a part of a girl up, and this continues until she's all tied up and gags her, then me moves to the next girl.
This can be done in many ways. The characters can be in either high school or college or even both. You're welcome to make it PG-17 if you can, but that's optional.
PM me if interested and have fun with it

EDIT: Found someone to work on it
