This watershed Japanese film is -- make no mistake -- borderline porn, with endless and explicit shots of male genitalia, insertions galore, and bodily fluids. The story is a simple one of lust and love (you decide which), with a couple (a man and his servant) falling hopelessly in love and experimenting with numerous sexual varieties, from domination to asphixiation and more. Typical moment: The dude inserts a hard-boiled egg into his girlfriend's privates, and she later asks him to eat it. But I don't know what's weirder: That an elderly geisha plays a stringed lute of some kind during most of their trysts, or that the girl later asks the guy to screw her. Creepy.

Aka Ai no corrida.
