Koumi-jima Shuu 7 de Umeru Mesu-tachi~ Ep 1

Seiichi, a teacher who enjoys visiting remote islands, is asked by an island chief to transfer to Ushihijima, commonly known as Childbirth Island. Due to the island's unique customs, its women have evolved a special constitution that takes only one week from implantation to childbirth. The island prospered for hundreds of years, but because the islanders only mixed with close genetic relatives, they now face a crisis: no children can be born without genes from outsiders. The chief's certain request to Seiichi is about to change everything. Catalog: avdb-h00396 (Hentai, produced by Hentai OVA, released on 2026-11-10, runtime 00:15:31).
