A guy gets caught masturbating by his step-sister

A man sets up a camera and walks over to the couch, where she continues to jerk his collar. The step-sister comes into the room, and he sees the guy masturbating and massaging his cock. She understands the assignment better. She goes ahead and bends over the couch and shows the guy her ass. The guy's cock gets super hard as he caresses the girl and jerks off.
