Yoshino Hanaoka is 55 years old. She currently lives alone and works part-time as an accountant on a temporary contract. She had almost no sex with her husband, and her flower as a woman had finally closed. But Yoshino blossomed again through an affair with Mr. A, whom she met at the temporary employment agency. It was the first time she had sex in 17 years, and she felt it, and since then, she has loved sex ever since.
