Wife to be Sacrificed (1974)

Director: Masaru Konuma
Stars: Naomi Tani, Nagatoshi Sakamoto, Terumi Azuma
What Five Minutes Were Like: Apparently Japan's been making torture porn since the '70s. Dude's pouring candle wax over this woman now, and she doesn't like it one bit (though in some movies they do). Honestly, she's tied up in such a way that doesn't make sense, unless he's slowly making her a rope kimono for his samurai S&M story.
