Shirley shares her masturbatory pattern while a narrator describes each of the steps in self-sexual exploration. She is first seen in the bathroom showering, drying, and brushing her hair luxuriously. In the bedroom she moves and strokes her body sensuously, gradually focusing in on her breasts and genitals. She then uses a vibrator on these areas, and moves into an exuberant orgasm. Close-ups show the vaginal area contractions of the pubococcygeus muscle during orgasm. Her delight continues to be visible after her orgasm, as she caresses and stretches her body.
