Your girl loses a bet. She has to get my guy off however he wants for a week. But she made sure to add the rule 'no fucking'. So what does that mean? They have to get creative. Each day is a different scenario. Will she love it by the end? Or just do it and be done with it.
Plenty of ways to play it out. High school teens. College kids. An older couple. Or even co-workers that are married but clearly are bored with their spouses.... There are ample other ways too. Feel free to shoot me with a suggestion!
