Son walks in and finds step mom on the phone having phone sex with dad. He tries to walk away but step mom gestures him over to her. She covers up the phone and tells him. “Not a sound” and winks at him. She unzips his pants and starts stroking his cock. She tells dad through the phone that she’s taken a dildo out to use it as a surrogate for his cock. She tells him to listen to her suck that hard cock, and then starts to suck off her stepson. She stays vocal so it can be heard through the phone, and dirty talks to her step son, which in turn, dad would think it’s for him. During the BJ, dad tells mum he’s about to cum so she vigorously sucks stepson’s cock to make noise. Dad thanks her and mom states she can’t wait for him to come home tomorrow.
