The men approach married women on the street under the guise of conducting a survey, but they don't stop so easily. They persist and offer a reward to lure them into the filming van, where they get to reveal details about their nighttime marital life. These married women are all somewhat sexually frustrated and love masturbation, but they still prefer real penis. Will these wives, gradually aroused by the pickup artist's teasing, abandon their chastity, thinking, "If only my husband doesn't find out..."? This time, they capture Reiko, a 32-year-old mother of one. She confesses to being sexually inactive since giving birth, but will she be able to find satisfaction with this thick cock she just encountered...?
