Koumi-jima: Shuu 7 de Umeru Mesu-tachi

Seiichi Ozaki, a single high school teacher, decides to visit a soapland—a type of brothel where clients bathe and interact intimately with prostitutes—to relieve his pent-up sexual frustrations. However, his journey takes an unexpected turn when he arrives at a remote island known as Koumi-jima, or “Childbearing Island.” This island, once a paradise where inhabitants freely fathered children with the most beautiful women, now faces a dire problem. After generations of inbreeding, the island’s women can no longer conceive without genetic material from outsiders.

Enter Seiichi, whose insatiable lust and virility make him the perfect candidate to solve the island’s crisis. The women of Koumi-jima, who have evolved to conceive and give birth within just one week, are eager to welcome him as their savior. Raised in a culture that glorifies male dominance and finds ultimate joy in pleasing men and bearing children, these women are more than ready to fulfill their biological and cultural roles.

As Seiichi steps into this bizarre yet enticing world, he finds himself at the center of a mission to repopulate the island. From the enchanting Komi to her mother Kaori and younger sister Riana, the island’s women are determined to ensure its survival—and Seiichi’s stamina is put to the ultimate test.
