Lately, Mike noticed that his stepdaughter River has been distracted from school. She’s in her senior year and she can only think about sex right now, so he forbids her from associating with any boys to keep her focus on her grades. However, River doesn’t like being told what to do, so she tricks Tyler, the harmless nerdy boy from class, into coming to her place to talk about a school project and convinces him to have sex with her in Mike’s bedroom. But that’s just the beginning of her plan, as River has more things in store to teach her stepdad a lesson about not messing with her.
