You are in your bedroom and stepmom comes in! She said she heard noises from my bedroom, busted! You give in and tell her about you and your stepsister. She starts telling you how wrong it is and your stepsister doesn't love you and will leave you! She convinces you that she should be getting your attention, you give in and she gives you a blowjob and rides your cock. Your stepsister comes in for a late night cuddle and catches you in the act!
