The Liberation of Cherry Janowski (1976)

The movie takes place inside the product-testing laboratories of Joyful Novelties, a pioneering sex toy company that takes its mission to unite all colors, creeds, and clitorises in sexual ecstasy as seriously as NASA took its mission landing man on the moon. If some had to lay down their lives in pursuit of the perfect orgasm--as one busty blonde does while connected to a prototype for a nuclear-strength vibrator--well, such are the pitfalls of progress. Suffering at the center of all this are Cherry Jankowski and the newly impotent Marcello Fettucini, two product testers whose vocational dedication to great sex has left them worn out and unfulfilled.
