Hidden in a desolate rural town lies a secret club where men gather to indulge in forbidden pleasures. Within this bathhouse—a brothel in name only—numerous underage girls work to satisfy male guests, offering more than just tender companionship. These young girls, treated like companions, provide exquisite service and openly offer bareback sex. Since they haven't started menstruating, pregnancy is not a concern, allowing them to receive each man's creampie deep inside their virgin vaginas, blushing shyly with every cumshot. This film starkly reveals the raw, hidden sexual reality of rural Japan.
