Miyoko Kujo, a 61-year-old lady with a noble and elegant presence. A homemaker who has spent the past 40 years raising three daughters and dedicating her life to her family. Her husband devoted himself to his career for decades, leaving little opportunity for the couple to truly share their married life. Just when she thought they could finally enjoy a relaxed, quiet life together after his retirement, he became absorbed in outings with friends, paying her almost no attention. Encouraged by her daughter who said, "Mom, you should enjoy your own time too," she found herself at a crossroads—until she came across a model recruitment ad. With nearly ten years having passed since her last sexual experience, she was tense and anxious, but determined: "Today, I want to discover a new side of myself," and "I want to let loose completely." Eagerly embracing the challenge, she was nursed by a young male actor, moaning in a sweet, childish voice as she writhed her fully mature body in ecstasy, thoroughly enjoying her first-ever affair.
