Koumi-jima: Shuu 7 de Umeru Mesu-tachi – Episode 1 (EN)

In Koumi-jima ~Shuu 7 de Umeru Mesu-tachi~ Episode 1, protagonist Seiichi—a teacher passionate about remote island travel—struggles with his overwhelming sexual endurance, finding no outlet for satisfaction. Invited by an acquaintance, the island chief, he transfers to Ushihi Island (nicknamed Koumi Island or Childbearing Island), where women possess a unique evolution: gestation and birth complete in only one week due to customs emphasizing feminine breeding roles. For centuries, this enabled rapid population growth, but inbreeding now blocks conception without new genetic input. The chief's desperate request? Use Seiichi's unmatched virility to impregnate every woman on the island and save their lineage!

Seiichi encounters the island's ultra-submissive females, who live for male pleasure, childbirth joy, and fulfilling primal instincts in a deeply male-dominant culture. They eagerly await his arrival to be claimed and bred repeatedly. This premiere episode kicks off the harem breeding saga with intense, heartfelt encounters as Seiichi begins his mission to repopulate the fertile paradise. Packed with creampie action, big breasts, and devoted masochistic females, it's a must-watch for fans of extreme impregnation hentai!
