For the in-discriminating viewer who simply wants a story about pretty naked girls in a lesbian embrace, this is the movie to see. There is not much plot to clutter the soft-core action, but there is an abundance of exploratory nudity. Director Nasu seems to suffer from delusions of importance as he treats the project more seriously than the thinly written story might deserve. His camerawork is creative, perhaps even innovative, based on the deviant angles he manages to capture. The plot itself deals with two high school girls who discover the pleasure of sex with each other until one of them chooses to be with a boy (!), then all hell breaks out.
Naomi, the short-haired chick and Miwako are not yet lesbian lovers at the start of the movie. Naomi hooks up with a guy, then she cheats on him with Miwako. The guy also fucks Miwako later when he has the chance.
There's a scene in the third act where Naoki rides her boyfriend on a beach chair while Miwako jealously watches from a window.
