I caught my step-son peeping on my while I was peeing on the toilet. I get shocked and say it's wrong. I tell him to leave but I see his hard cock and it starts to make me horny. I can't help, I know it's wrong but omg. I tell him to come closer and I start to touch my pussy, I tell him to jerk his cock for step-mother. I ask him if he wants to see his step-mother peeing on the floor, and then I do it. Then we go to the matress and and I pee on his cock, chest and face. I then sit on his cock, he licks me peed pussy, we fuck in different positions and by the window too. Sometimes I tell him to stop cause its wrong, but not for long cause we cant resist each other. I tell him to fuck my ass, we fuck in different positions too and he cums in my asshole . I keep dirty talking all along. At the end, I pee on his face before step-dad arrives.
