Koumi-jima Shuu 7 de Umeru Mesu-tachi

Synopsis

Based on the CG collection by Aomizuan (青水庵). The protagonist, Seiichi, works as a teacher and has a passion for traveling to far-flung islands. Though endowed with extraordinary virility, he finds his routine existence lacking. One day, an appeal arrives from the chief of an island he already knows, and he ends up being stationed at Koumi-jima—an island nicknamed Childbirth Island. That "favor" turned out to be... Owing to the island's longstanding practice of emphasizing the feminine role, the women here have developed a singular biological trait: only one week elapses between conception and childbirth. This distinctive way of life has allowed the island to endure and prosper for hundreds of years. But because the inhabitants have intermarried only among their own close bloodlines for so long, they've now reached a dead end where only genes introduced from beyond the island can produce viable newborns. The island chief's plea to Seiichi, a remarkably potent man carrying outside genes, was: "I want you to impregnate all the girls on the island." That was the request! Given the island's custom of prioritizing the female role, the women long to gratify the instincts of men who hold deep-rooted convictions of male dominance. What fate awaits these women, who derive ultimate pleasure from serving men and bringing forth children, when Seiichi steps onto the scene??
