When I came to Tokyo to take my university entrance exams, I ended up staying at the house where my eldest son and his wife lived, as well as their second son and his wife. Coincidentally, the two brothers were on a long business trip, and a strange cohabitation began with the two brothers' wives. There were only three days left until the exam, and I was studying as hard as I could, but I couldn't get my brother's wife's beautiful butt out of my mind, which I could see even through her G-panties. In the midst of all this, he said, ``It's important to take a break when studying for entrance exams.''
