Under the guise of therapy, Dr. Julia Robbie exploits the incestuous tension between step-siblings Cecelia and Anthony. She guides them through explicit role-plays, encouraging them to express their forbidden lust. On the couch, they explore each other's bodies, their moans echoing as they push boundaries. Dr. Robbie, in her professional attire, remains a voyeur, yet her presence fuels their kinky session, making it clear that this is no ordinary therapy.
