Come on, let's start our maternity life!!
In a world of cuntboys, men are also capable of pregnancy and childbirth. Guest, the husband of Akito Sasaki, and Yuzuki, the husband of Iori Kannagi, have both just discovered they are pregnant at almost the same time. They are still in the early stages, and their bumps aren't showing yet. Iori, who won a massive lottery jackpot, built a 300-million-yen mansion for Yuzuki. However, feeling lonely in a house far too large for just two people, Yuzuki suggests to his best friend Guest and their husband that they move in together. Thus begins the communal life of two pregnant men and their two doting husbands. Akito, calm and overprotective; Iori, grand and prone to spending sprees; Yuzuki, the pampered sweetheart; and Guest. From pregnancy life to shopping for baby gear, childbirth, and childcare, the four of them will spend their noisy yet happy days cooperating together. Guest is a cuntboy.
