A married woman visits an anal trainer at her husband's request. Hesitant at first about receiving training from a man other than her husband, she gradually begins to succumb to the pleasure. Bound in a spread-eagle position, her body is intensely stimulated using various devices—vibrators, fingers, dildos, and anal vibrators—thoroughly assaulting both of her orifices. Scenes depict her screaming as pain and pleasure intertwine.
