Sam is enjoying a quiet wank in his room when the door opens and his step mum Francys peers in. She is shocked to see him jerking off but he doesnt notice and she watches for ages. Then she walks in and surprises him, telling him to carry on as she wants to watch. He finds it weird but wanks for his sexy step mum as she controls his speed. She then pushes his hand away and takes over, stroking his big cock expertly until he shoots his cum all over her hands!
