Nunnery Affair: The Inverted Manji Hanging (2005)

One stormy night a forestry worker, returning from investigating a landslide finds himself unable to return to town and seeks refuge at the temple. Unable to abandon the desperate man, the head priest invites him in. However, the man becomes aroused by the head priest's beauty and rapes her. The man's body, which she hadn't touched since her time in the secular world, reminds the head priest that she is a woman. From then on, the head priest indulges in masturbation while secretly watching the sex of a couple, the daughters of the temple's parishioners. One day, while she is masturbating, the forestry worker from before comes along and sees her. The man grins and says he'd like to teach the head priest even more extreme sexual pleasures, and then he ties her up with a rope...
