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 has large, firm breasts, and I was aroused and couldn't sleep. The next day, we were again sleeping in a row. I woke up feeling uncomfortable and saw that my mother-in-law was touching my crotch. Then she asked me, 'Weren't you rejected by your wife? Isn't this uncomfortable...'
