I love my father-in-law more than my husband...

Yua marries her childhood friend Yuma. My father-in-law Toru also knew Yuai since he was a little kid, and he always helped me whenever I was in trouble. One day, Yua came to this town where she was born and raised. My father-in-law's house has not changed since ancient times. Yua finds out that Yuma is cheating on her, and runs out of the house. Then, he pushes his father-in-law down, who had secretly liked him for a long time, saying, "Please don't tell Yuuma that you've come here," and boldly takes the cock in his mouth...
