"Because I have little experience with men, I wonder if I don't really know the true pleasure of sex..." Yuuki Aoi, 30, works in sales administration at a local company and is a mother of one. Currently, she is leading a fulfilling yet busy life with work and childcare. However, occasionally, she wonders what would happen if she had sex with a man other than her husband. Entering her fifth year of marriage, she feels the decline in the passion of their marital life and becomes even more drawn to the unknown pleasures. The image that comes to mind is that of an actress from an AV she once saw, wildly enjoying herself. "Since I was born a woman, I want to experience that at least once." Aiming for the peak of pleasure that seems unreachable in marital life, watch as this virtuous wife decides to appear in an AV and accepts the second man in her life.
