VENU-803 Suddenly, my wife's sister barged in and made me cum non-stop for one night and two days

(I did it...) Yoshinori has betrayed his wife. That's because his sister-in-law, Yuu, is in front of him. Yoshinori was enjoying the freedom of living alone for the first time in a long while when his wife went on a one-night, two-day trip. Then suddenly Yuu comes to play with her. As a matter of fact, Yu had come to relieve her frustration with her Yoshinori, but she invited her in without her Yoshinori knowing. Yoshinori, who took care of Yu who did her housework, took a bath and Yu also came.
