Takashi's wife left him over a trivial matter. Hearing about a huge fight between the couple, his wife's sister, Shiori, came to his aid, and Takashi couldn't help but blurt out that he would do anything to make up for it. "If it's anything you want...hold me." Takashi never expected that she would demand his body in exchange. He was approached by her snow-white, voluptuous, beautiful breasts and body, and ran away at first, but he couldn't go back on his promise.
