A documentary following a popular married woman's volleyball team based in Kanto. At first glance, they seem like any ordinary married woman's volleyball team; however, there's one unique rule that sets them apart—swapping partners among the dads in the group. "This month happens to be my turn," says the most popular mom on the team, Tsukki-Mama at 25 years old. As long as she doesn't react, it isn't considered cheating! The moms participate in a rotation system where members agree to have consensual sexual encounters with each other's husbands. Each mom gets paired up with a different dad during her turn. While some admit to having extramarital desires, they value their families too much to risk destroying them. Note: The contents may vary depending on the recording method used.
