"I feel like I don't know the pleasure of real sex because I don't have much experience with men..." says Yui Yano, 30 years old. She is a mother of one child and works in sales administration at a local company. She is currently leading a busy but fulfilling life with her job and childcare. However, sometimes the thought of what would happen to her if she had sex with a man other than her husband comes to her mind. As she enters her fifth year of marriage and begins to feel the decline in her married life, her yearning for unknown pleasures grows even stronger. The image that comes to her mind is the image of an actress who goes wild like crazy in an adult video she Itsuka saw. "Since I was born a woman, I want to be like that at least once." Watch as this faithful wife, who decided to appear in an adult video in order to reach the heights of pleasure that she could not reach in her married life, accepts the second cock of her life.
