A request for "cuckolding" is made to the organizer of a swapping enthusiasts' circle. This time, in a special episode, married woman S-ka (29 years old) is taken on an overnight trip. After six months of persuasion, the wife finally agrees to the cuckolding trip. She arrives at the inn with a gloomy expression on her face, and becomes completely tense when a man bursts into the open-air bath. She resists the man's advances, but in fact, her genitals are soaking wet. She is then at his mercy, gradually beginning to moan and writhe in ecstasy. After dinner, the drunk wife is molested, and while writhing in pleasure as she is stimulated with a vibrator, she calls her husband to report on the experience. She lets her husband hear her orgasmic cries, and then reports on the man inserting his penis and reaching another peak. The wife climaxes multiple times, sweat streaming down her forehead. The next morning, she seems to have let go, greedily seeking pleasure and going wild.
