Kayoko Hisakura is 50 years old. She lives a peaceful life with her husband, who is an office worker, and her two daughters. However, she is dissatisfied with her daily life... She has never been satisfied with sex with her husband. Recently, she has been reading about sex with people her age in magazines and on TV, and it made her want to experience sex that feels really good as a woman. Although she was confused by the various acts she had never experienced before, she got her big nipples erect and her unkempt pubic hair soaked as she came over and over again.
