The young stepsisters had always been a bit too close for comfort, according to their strict stepmother. She decided to seek professional help and scheduled an appointment with a doctor at the hospital. Little did they know, this was no ordinary therapy session. The doctor had a unique approach to his therapy, one that involved a lot more than just talk therapy. He had a rather large proposition for the two girls. He introduced them to his massive member, a sight that left them both in awe. The doctor, being the deviant he was, insisted on treating them right then and there on his plush sofa. The girls, being the curious creatures they were, couldn't resist the allure of his monstrous cock. They eagerly took turns sucking on it, their small and petite bodies struggling to accommodate his girth. The doctor, with his expert hands, made them both climax, leaving them both completely satisfied and fulfilled.
