Kimiko Yoda, a 56-year-old housewife. Married for 29 years, her life with her husband had been long and stable, yet an undeniable desire had always stirred within her. Her striking 100cm G-cup breasts concealed a deep, powerful sexual appetite. She had suppressed these urges through years of marital intimacy, but a year ago, her husband reached the end of his sexual ability, bringing their conjugal life to a halt. As their 30th anniversary approached, she began to feel a profound emptiness deep inside. Though love remains, her husband's body can no longer satisfy her. Driven by this longing, she seeks a new partner and dares to experience her first affair through adult video—marking the beginning of a new journey born from 29 years of marriage.
