Fucked my stepsister to take revenge for the fact that my stepmother stole my father from the family

Dad invited his son to a barbecue and said that he was going to introduce him to a new woman. The guy was not happy with this turn of events, but then his stepmother’s daughter came and the conversation immediately changed direction! Just imagine, this bitch turned out to be so anxious that she sucked him off in the presence of her mother. She, however, did not notice anything: she was too busy cooing with her new husband... Although, perhaps, in their whore family this is considered the norm.
