A hot spring trip for two men and women who are drowning in pleasure by hitting each other's bodies with lust. A omnibus of director Koichi Takahashi's selection of works from the "Mature Woman's Sexual Journey" series, which condenses the conflicts and eros of mature women who have lived a turbulent life. The second theme is "Dense luster". A mature woman who can't stop her delusion while working in a video box is caressed in an open-air bath and her face and female genitals are turned into a tortoise. A 240-minute work containing 3 titles selected under the theme of a mature woman full of lustrous and sexual charm, such as shaking the whole body and repeating cums many times when welcoming a cock.
