Here's a plot idea I've had in my head for a while:
A high school is groped on the bus or subway by one or more men on her way to school. Later, at school, she finds a group of her male classmates watching cell phone footage of the incident. She can be recognized in the footage, so they blackmail her into having sex with them.
Could be short term or long term. Willing to play either the guys or the girl in the scenario. This could also be a femme scenario, with a group of girls being the ones to want to take advantage.
Any takers? Threading, PB only, and willing to discuss details in a custom.
