"Lately, with my youngest child safely reaching adulthood and celebrating Coming of Age Day, I feel relieved—but at the same time, I've started to feel something like 'the end of my life' approaching," says Chihiro Yoneyama in a calm voice. At 54 years old, married for 28 years, and a full-time housewife, her sense of "life's end" comes from the satisfaction of completing her role as a mother now that her children have grown, coupled with inner conflict about how to live the rest of her own life. She's had only two men in her entire life, including her husband, and has long felt that something inside her was missing. Now, more than ever, she desires to enjoy her life as a woman more fully. Determined not to regret anything when she reaches her 60s, she wants to cherish this very moment—watch her commitment, her daily masturbation routines to satisfy her sexual desires, and focus on her longing and lustful heart.
