My mother-in-law came to Tokyo and stayed at our house. However, the house is small, so my wife and I had to sleep in a row with my mother-in-law. My mother-in-law is slender and big-breasted, and I got aroused and couldn't sleep. The next day, we slept in a row again. Late at night, I heard moaning from my mother-in-law. I watched her pleasuring herself quietly. The next day, after confirming that my wife had left, I hugged my mother-in-law and told her what I saw the previous night. I pressed my already hard lower body against her, and she knelt down and pleased me. Then at night, the three of us slept in a row again. I woke up feeling something strange in my lower body and found that my mother-in-law was sucking on my crotch...
