Intimate Games (1976)

The entire movie is about a college class studying sexual experimentation and fantasy. Sexual themes and discussion are prevalent throughout. A secretary comes into a businessman's view several times, each time he imagines less and less of her clothing until eventually she is naked save garter and stockings. Her breasts and pubic area are clearly visible for several seconds. A young woman is being tormented on a stake for educational purposes. Her breasts and stomach are exposed. Three young women are shown in their dorm room in various stages of dressing and undressing. Breasts and pubic areas are visible.

In what is obviously a fake film for educational purposes, a woman is tied to a stake with flamed flowing around her, and a man is beaten and tormented under a harsh light. No blood is shown.
