Mom gets new outfit delivered so tries it on and decides to start playing with herself but her son walks in! She notices he got hard from watching her. She tells him its ok- its their secret- obviously all people masturbate and starts asking him questions what he masturbates to. She strips down and finally ends up getting the answer that his hottest fantasy is about girls peeing. She stands up and pees for him on the floor telling him to stroke to her peeing. He cums to her peeing.
