You are my stepson and you are studying to become an OBGYN. You tell me you HAVE to study with a real woman tonight - you are a visual learner. It takes some convincing of course because of our relationship. But I think if we keep it professional, I mean - you’re studying to become a DOCTOR, right??? Anyway, I give you a bit of a run-down of all my female parts (which you should already know, btw) and you ask me silly questions in order to get me to stretch my hole wider for you. You need to be able to see inside. You don’t know it, but this stepmommy can actually fist herself… and it turns me ON! I get wider and wider for you, becoming more turned on as we continue. Eventually I show you with my dildo, and eventually you can’t contain your boner. I am actually impressed!!!! I decide to take my own stepson for a ride and cum HARD all over your dick! Some biology lesson.. huh?
