Yasaki Yui, 36, is a working caregiver and celebrating her 10th year of marriage. Influenced by her kind grandfather from childhood, she has developed a preference for older men. Her husband is a 57-year-old man approaching retirement, making them a couple with a 21-year age gap. They have successfully had children and enjoy a happy family life, but recently she has grown increasingly dissatisfied with their sex life. "My husband can hardly get an erection anymore... Lately, I mostly resort to pleasuring myself." Watch as this married woman opens up about her new resolution after a decade of marriage—to experience sex with younger men.
