Adrianna and Sia are stepsisters who do everything together. Their Perv Therapist, Dorian, is particularly interested in their porn-watching habits. Adrianna and Sia love stepsis porn and pornos where patients get with their doctor. Dorian wants to make their fantasy a reality, so he initiates a bit of roleplaying and puts on porn for the two babes to masturbate - this seems like the type of therapy the girls could get used to!
