In a fictional world facing falling male libido, lower marriage rates, and declining birthrates, the government introduces the ZO Act: women attend matchmaking parties completely naked, and couples who successfully match and achieve conception through a creampie receive state support. Male guests can inspect the women's naked bodies as they display their tits and pussies, while also peeking at other participants. The goal is to form a couple and advance to a private creampie conception session for two.
