Koumi-Jima Shuu 7 De Umeru Mesu-tachi

Storyline & Plot Overview

On the secluded and forgotten island of Ushihi, the local population faces a dire existential threat: a collapsing gene pool caused by generations of isolation. To salvage their lineage, the village elder recruits Seiichi—a disillusioned teacher harboring a “hidden physiological gift”—to undertake a mission unlike any other in human history.

Seiichi’s task is as exhausting as it is extraordinary: he must impregnate every woman on the island to refresh their genetic diversity. In a bizarre evolutionary twist, the women of Ushihi have developed the ability to complete a full pregnancy cycle just one week after conception. For them, the act of conquering a man to ensure the survival of their clan is not just a duty; it is the ultimate expression of ecstasy.

Upon arriving at his island lodgings, Seiichi meets Konomi Tachibana, a vibrant and irresistibly provocative young woman. Konomi is not merely willing to fulfill her role; she is consumed by a desire to bear at least five of Seiichi’s children. Her relentless aggression, combined with the unbridled advances of the other island women, transforms Seiichi’s life into a blur of “physical exhaustion” amidst a never-ending cycle of carnal pleasure.
