Christie Stevens, Dana Dearmond, and Marica Hase enroll in a unique course where the curriculum is their insatiable desires. Their MILF professor, a seasoned expert in lesbian kink, leads them through a series of explicit, taboo lessons. Today's agenda: anal fisting. Marica, the submissive, is first to volunteer, her ass gaping as the professor's skilled hands stretch her. Dana, the eager student, watches, her pussy aching to be filled. Christie, the dominant, takes charge, strapping on a massive dildo and fucking Dana's tight cunt while Marica services her from behind, turning the classroom into a symphony of moans and sloppy, wet sounds.
