In a cramped therapy room, Dr. Sophia Locke, a sultry Aussie-Canadian hybrid, prescribes a unique form of therapy for a couple's sexual dysfunction. The husband's penchant for porn and fetishes must be addressed, and Dr. Locke believes a threesome is the best solution. With Theodora Day joining the session, they explore each other's bodies, with Dr. Locke expertly guiding them through a maze of tongues, lips, and pulsating flesh. The wife watches, her eyes wide with surprise and desire, as her husband's fantasies unfold before her.
