A group of friends from the Exploration Club head to a southern island for a vacation but their boat gets shipwrecked on a mysterious uninhabited island in another world. The island, called Harem Island, has 99% women and very few men. A god appears in their dream and asks them to revitalize the island into a popular tourist destination so they can return home. They meet beautiful island women and start working hard while enjoying explicit harem encounters with deepthroat, paizuri, raw pounding missionary doggystyle and creampie overload
