The back box cover explains that this indoor aquatic sex frolic takes place during a frat house party, but it must be the smallest fraternity in the Czech Republic given that there are only four guys in attendance. On the plus side, they're four pretty cute guys. They have two attractive female guests that slip out of their little black dresses once the boys start lobbing a beachball at them, and then the party really begins. The interactions, both same- and opposite-sex, are great fun to watch. Unfortunately, the camera slips out of focus an annoying amount of time.
