My stepmom barges into my room while I'm masturbating and tells me I'm grounded unless I masturbate In front of her. I start touching myself in front of her as she's telling me how fast and how slow to rub my pussy and it just starts feeling better and better with her instructing me to the point that I can't stop, I want to please my stepmom and make her happy..... and not only when it's to get out of being grounded either
