Stepmother denies my advances but encourages solo masturbation and cumming in her hairy pussy

My friend\'s stepmother is a hot, voluptuous vixen with a big, juicy ass and a hairy pussy. She\'s been denying my advances, but when I\'m around, she can\'t help but rub her juicy cunt. I\'m always lurking, watching her every move, ready to join in and make it a wild ride.
