The beautiful wife Tsunobu came home to her in-laws. Because her father-in-law was seriously ill, she came to take care of him. One day, when he got better and we were preparing to leave, we suddenly heard him crying out because he discovered that his wife was cheating on him. Feeling heartbroken, I stayed to comfort him and we shared a few drinks together, but before long I fainted and had no strength left in my limbs. When I woke up, I found myself helpless in the scene of my father-in-law making love in front of my mother-in-law. I was heartbroken, and my father-in-law seemed to be provoking my mother-in-law, and there was nothing I could do but endure.
