Deep Throat

A sexually frustrated woman (Linda Lovelace) asks her friend Helen for advice on how to achieve an orgasm. After a sex party offers no help, Helen recommends Linda to see a doctor. The doctor discovers that Linda's clitoris is in her throat and after helping her develop her oral sex skills, the loving Linda asks him to marry her. He tells her that she can settle for a job as a therapist by practising her special oral technique - hereafter called "Deep Throat" - on various men until she finds the one she wants to marry. In the meantime, the doctor documents her exploits while having repeated sex with his nurse. The film ends with the line "The End". And Deep Throat for you all".
