In a cramped therapy room, Penny Barber, a mature and experienced therapist, facilitates an intense session between April Olsen, her stepdaughter, and Dan Ferrari, her stepdad. April, a busty teen with a big ass, is clearly attracted to Dan's big cock, while Dan struggles to keep his hands off April's curves. Penny, noticing their unspoken desires, suggests a unique form of 'therapy.' She guides April through a sensual masturbation session, then teaches her how to pleasure Dan with her mouth. Soon, the room is filled with moans as Dan's cock slides in and out of both women, leading to a intense, taboo-filled orgasm that leaves them all craving more unconventional therapy.
