Step-Sister comes home and sees her step-brother having sex with his girlfriend and decides to watch her stepbrother fuck. She starts masturbating, getting carried away, and eventually he catches her. Before she has a chance to run up to her room, he confronts her and he starts feeling how wet she got from watching. He's upset he got interrupted, so he flips her over and starts feeling her, slipping his raw cock inside of his stepsister. She moans and takes it, pleading him to pull out. He doesn't listen, and even though she's begging, he fills her up with his fertile cum regardless. Maybe getting pregnant will teach her a thing or two about privacy...
