Asami, a mother-in-law, came to Tokyo for a limited time from the countryside to take care of her pregnant wife. Her mother-in-law made our lives comfortable, but my heart remained unsettled. The reason was that her wife had told her not to masturbate until she gave birth. Her mother-in-law treated me kindly as I was not feeling well, but my beautiful face and sex appeal were spurring on the days of frustration. And one night, when I couldn't stand it and was masturbating, my girlfriend's mother-in-law found me.
