The One In Control (Femdom, Chastity)

Learning to drive is difficult enough as it is, but it's even more challenging for Gemma when her driving instructor, Martin, begins to grope her during lessons. Unfortunately, Martin won't take no for an answer and so she decides to teach him a lesson. She promises to have sex with him as long as he wears a chastity cage until she passes her test. He soon discovers who's really in control.
