Jones1975's step-sister, Teresa, thinks she's sneaky, but her masturbation in the car doesn't go unnoticed. As she rubs her clit and fingers her pussy, she catches him watching. Instead of stopping, she invites him to join, pushing his hand onto her wet folds. He hesitates, then eagerly pleasures her. She sucks his cock, then straddles him, grinding her hips until they both cum, leaving them breathless and guilty in the parked car.
