Based upon a true story (more commonly known in Nagisa Oshima s In the Realm of Senses ), this well filmed, well acted Japanese movie is as much a contribution to the infamous pink film genre, as it is a fascinating tale of the wild and weird ways that sexual obsession leads to. Kaio, as Abe Sada calls herself, and her boss Kishi are drawn into an amorous affair and totally forget about the outside world. They stay in their hotel room and day-in, day-out they spend their time in erotic games, exploring all aspects of physical love and gradually going further and further, until... The obsession is physically visible, but no doubt is left that the real obsession takes place in the minds of the protagonists. A forgotten gem, interesting, provocative and highly recommendable.
