The organizer of a swinging enthusiasts' circle presents a "cuckold" request. This time, a special trip with married woman Risa (30 years old). She agrees to be cuckolded, saying, "This is just for today..." However, unexpectedly, she harbors a secret—she's a lesbian. Her relationship with her husband is always gloomy; though she receives foreplay, her reactions are weak, yet her genitals are slick and wet. When taken from behind in an outdoor hot spring, she moans, "It feels strange..." and her expression suddenly changes. Back in the room, as the penis enters her again, she begins to cry out in pleasure, eventually uttering the words, "I love cock." After dinner, at her husband's request, she performs masturbation for him, then fiercely sucks the offered penis, repeatedly engaging in titty fucking in a state of extreme arousal, bringing him to ejaculation—an ultimate depiction of climax.
