I came to Tokyo to take my university entrance exams, and ended up staying with the eldest and second sons' wives. By coincidence, my two older brothers were on a long business trip, so I started living with my two brothers' wives in a strange way. With only three days left until the exams, I was studying as hard as I could, but I couldn't get my head around my sister-in-law's firm, perky ass, which I could see even through her jeans. In the middle of all this, she pushed me down and said, "When studying for exams, it's important to take a break..." and until the exams, her beautiful ass kept sucking my sperm out, whether I was awake or asleep...
