The beautiful wife tsunobu went to her husband's parents' house. Because her father-in-law was seriously ill, she came to take care of him. One day, when he was well, we were about to go home when we suddenly heard him crying because he discovered his wife was cheating on him. Feeling heartbroken, I stayed to comfort him and drank a few glasses of wine with my father-in-law, but after a while, I fainted and my arms and legs had no strength left. When I woke up, I felt helpless before the scene of my father-in-law making love to my mother-in-law. I was in pain, and my father-in-law seemed to be provoking my mother-in-law, and there was nothing I could do but endure it.
