I am home for summer break. Stepmom is gone on a work trip and it's just you and me alone, stepdad. I've caught you checking me out when you thought I wasn't paying attention. But I was. Why don't you show me how hard your cock is? Haha, I took a photo of it! If you don't want me telling stepmom, you'll do whatever I say. You are going to be my personal fuck toy all summer. I am going to ride you and fuck you until I cum. I don't care about your orgasms. I only care about myself. You'll keep this kinky secret between us. Or else your marriage is ruined.
