On a remote island, a female doctor is the sole caretaker of the islanders' health... According to the island's rules, she must also take care of the sexual needs of all the islanders while performing her medical duties. Gentle handjobs, deflowering virgin islanders who are leaving the island, late-night oral sex, and threesomes on the beach... This is the story of a Kokoro female doctor who eagerly accepts the islanders' sperm and dedicates herself to them, set against the backdrop of beautiful nature.
