Pals Toshida (Wani Kansai) and Uno (Toushi Yanagi) insist on going to a brothel with their betrothed friend Nakazu (Yuya Ishikawa), who has never paid for sex before. Each guy is matched with a nubile prostitute, unaware of the locale?s deranged mission to sexually torture customers. Vagina dentata is the yarn?s main means of attack, but samurai swords and phallic food games provide plenty of ketchup.
