I am in my bedroom, masturbating, while my little step-brother rushes into my room without knocking. He caught me masturbating right when I have a really intense orgasm. He blackmails me that he is gonna tell step-mom and step-dad what he just witnessed if I don't suck his cock right away. I laugh in his face and tell him that's not going to happen. He, then, wants to leave and tell our parents. I accept to suck his cock, which turns out to be very big. He cums all over my boobs and then he blackmails me again that he will tell our parents I sucked him, if I don't accept to fuck him the next night(Part 2). *Part 2 is already recorded and will be up soon. Stay tuned!* Contains: taboo, kind, sis roleplay, masturbating, orgasm, POV, blowjob, sex doll, dirty talking, moaning, blackmail fantasy.
