The newlyweds, Mr. and Mrs. Asano and Mr. Yamamoto, are acquaintances of regulars at the orgy club. Both of them are married to wives a year younger than them and have played the role of good husbands, but they want to come out about their sexual inclinations and enjoy NTR as a couple, so they ask the organizer of the orgy club to arrange and film a swapping party. Ayumu and Rui are confused after hearing the story from their husbands, but they come to the hot spring resort, and in the steam of the hot springs, a crazy wife swap and orgy party begins!
