Women born in the Showa era, married women in their sixties to seventies, exude charm with their skillful makeup and beauty, maintaining their bodies through dedicated fitness routines, achieving soft, plump, and bouncy physiques. This erotic documentary drama portrays 36 mature women aged 28 to 74, born from Japan's postwar reconstruction period through the bubble era. Traveling across Japan—from the far reaches of Hokkaido to Sakurajima in Kyushu—the film explores their desires and pursuit of pleasure. For these mature women, easy targets for affairs are middle-aged male relatives or nephews—men who are discreet and well-endowed, capable of stimulating their sexual instincts and satisfying them with exceptional sex. Also revealed are the wet, hidden desires of seemingly modest and virtuous housewives in rural areas, pounded relentlessly by AV actors during surprise on-location shoots. As the second installment of the Sensual Masterpiece Erotic Film Theater series, this film vividly captures lust and ecstasy, set against Japan's timeless natural landscapes through the seasons.
