This summer, Matsunaga Chieri, on the verge of turning 40, faced a major turning point in her life. After nine years of marriage and growing apart from her husband, she made the decision to divorce. At the same time, she resolved to pursue a new dream—making her debut in adult videos. As a divorced woman, she experienced one after another the "first times" she had never known while married—the first time being passionately taken by another man, the first time cheating, the first time fully surrendering to desire. All of it is captured in raw, unfiltered gonzo style across four intense sex scenes, documenting her bold transformation in this debut work.
