Synopsis
Based on the adult game developed by Lune, this is an advanced sequel to Jutaijima. A school trip takes a deadly turn when a ship carrying students on a holiday voyage is suddenly battered by a storm. The survivors find themselves stranded on an unknown island. There, the girls begin acting strangely due to a mysterious virus that spreads on the island. The infection causes them to become aroused and lose control of themselves. The only way to resist the virus is to receive regular doses of sperm, which grants immunity to its effects. If a girl does not get enough sperm, the unrelenting arousal will trigger a fatal heart attack.
