A married woman responds to a "cuckold" proposal from the organizer of a swinging club. This time, S-mi (27 years old) from "Yukemuri Tabi 22" embarks on a special couples trip with her husband. She claims their relationship deepened after their previous trip and agrees to be taken by another man right in front of her husband, if it brings him pleasure. Upon arriving at the inn, the three of them begin with a celebratory drink. When her husband leaves to buy more alcohol, a man takes the opportunity to make his move. Though anxious about her husband's return, the married woman is highly sensitive to the man's touch and quickly melts into blissful reactions. Meanwhile, her husband has already returned and secretly watches, capturing the sight of the man thrusting his cock into his wife as she writhes in ecstasy. Then, right before her husband's eyes, she straddles the man and grinds her hips, riding the waves of pleasure. Later, after some private couple time together in the bath, they resume drinking. When the man briefly steps away, the couple begins having sex, but the man soon rejoins them, escalating into a threesome. The wife finds greater pleasure with the stranger's cock, moaning and convulsing intensely as she's ravaged by the outsider.
