My husband's father wanted to give me his house, so I decided to go to his parents' house for the formalities. Yui used to tolerate her kind and attentive father-in-law, but when he caught her having sex with her husband, the next day when they were alone, Yui realized that he could satisfy Yui better. Her father-in-law seduces her and makes her do it. Yui, who had been resisting, was made to cum over and over again by her stepfather, and she became captivated by the pleasure.
