Yukika Kamine, 47 years old, has a perfect body. Her 'beauty secret' is the promise she made to her husband at the time of her marriage, 'stay beautiful...', which she has kept for 20 years since her marriage. Her beauty feels like she's at her peak right now. However, she has been sexless for several years because of her husband's physical strength. At that time, she admired the shining appearance of the AV actresses she saw on the net, and came to the studio to release her body that she had continued to polish and her lust hidden inside her.
