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 father-in-law, and she became captivated by the pleasure.
