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