I live with my girlfriend and my mom comes to visit us frequently. When is a social visit she only comes on weekends, that are the days we both are at home. When my mom comes for sex, she visits on work days, during work hours, on my off days at work, and when she knows I'm home alone. Some of our neighbors know her so she likes to be undercover, wears a wig so the neighbors don't know it's my mother and eventually tell my girlfriend she visits me often. She likes to wear the wig while I fuck her, she says that it makes her feel a slut.
