Shiori and her husband are a loving couple ready to have a baby, so they plan a fertility trip around her ovulation day. After visiting a shrine to pray for a child, they intend to spend the night having unprotected sex at their inn, with no condoms packed because pregnancy is the goal. Her husband promises to fuck her until morning, unaware that a group of adult college role-play guys have set a trap that ends with Shiori receiving multiple creampies.
