Sexaholics (2000)

Mrs. Seville is a sex therapist that has a strong hold over her latest therapy group... filled with patients who are "Sexaholics." The group proves very challenging, as two of them sneak off for a "quickie" even before the first session begins. As each member of the group relates his or her experiences, everyone gets turned on. As Ms. Seville counsels each, alone in her office, total sexual chaos takes place outside. By the time she has talked to each patient, she has lost much of her willpower. She finally succumbs to one of the girls she is treating. The session's end with the therapist turned patient... confessing to the whole group her inability to cope with unbridled sex. Naked, the group then cluster around her!
