During the family vacations, you've been spying on step-mom any chance you get. Watching her turns you on. One day, she gets in the bathroom but leaves the door open. You watch her shower, and when she finds out you're there, she's not upset; she agrees to help you with that boner. Then, while the rest of the family is outside, you and step-mom lock yourselves in the bathroom so she can suck your cock and you can fuck her and cum deep inside her pussy, like you've always wanted. Now you and step-mom have a little vacation secret.
