Novel skin flick concept. Japanese performers turn an offshore, underwater lagoon into their sex lair. But lo, this story has more to it than just sex. This video examines the cultural mores of modern society versus ancient civilizations.

Three college friends vacationing on a remote tropical island discover more than they bargained for in the local inhabitants. These savages lack the carnal knowledge of educated city folk. In their world, sexual activities are limited to procreation, not recreation. Witnessing the vacationers during various states and positions of coitus, the locals decide to see what all the fun is about. In time, they learn the joys of ball tonguing and rim jobs. Meanwhile, the philosophers sit around pondering the possibilities of dropping out of their workaday world and living the simple life on an island paradise.

The obvious draw to this material is the scuba sex scenes, all lit well and featuring some fascinating positions. Casting adorable Japanese girls doesn't hurt anything either. One of the more interesting aspects of this sort of novelty-porn, is the underwater pop. The released jizz has an ethereal quality to it, floating around in the azure water.

This is porn that is at once sophisticated and innocent, premodern and postmodern - and above all, erotic and entertaining. In Japanese with English subtitles.
