Marine Rouge

A young man named Kenji decides to have a vacation on the beautiful island together with his sister Hiromi. Taking a break from work and worries, the two discover a tourist resort with lovely beaches and high-class hotels. Very soon Kenji finds out that many attractive young women either work on the island or have come there for various reasons. Soon the holiday turns into a never-ending string of sexual escapades - and perhaps one of them will turn into a true romance?
