31-year-old housewife Kanan Mizuki, who started going to a gym in Setagaya Ward. Beginning to visit the gym due to sexual dissatisfaction in her marriage, she decides to make her AV debut in search of pleasures unattainable through sports. Thanks to her twice-weekly workouts, she develops a toned body and a luscious, glossy "pussy." Depicted in this documentary-style adult film is her repeated climax, as sweat and arousal mix. This is a close-up portrayal of Kanan's "first affair" and "first adult video shoot," capturing the moment she experiences intimacy with a man other than her husband for the first time since getting married.
