​In “Island of Lust,” a group of castaways must navigate a mysterious island plagued by a sexually-transmitted virus. This virus, if left untreated, induces insatiable arousal and ultimately proves fatal. As they grapple with their predicament, the tables turn for Ai, who once bullied the only male student in their class, now forced to engage in sexual encounters with him. Tensions rise when Yumi, consumed by jealousy, takes control and engages in explicit acts in front of Ai. Even Akira, who initially struggled to suppress her own sexual urges, falls prey to the allure of his semen. Will this group of students ever find a way to escape the clutches of this island, or are they doomed to remain enslaved by their desires?​
