The mother-in-law satisfied her son-in-law at midnight because his wife was pregnant

Asami, a mother-in-law, comes to Tokyo from her hometown for a limited time to take care of her pregnant wife. Thanks to my mother-in-law, our life has become comfortable, but my mind is still restless. The reason was because his wife told him not to sexually harass her until the child was born. My mother-in-law treated me kindly because I was not feeling well, but my pretty face and attractive features became brighter day by day. And one night, my mother-in-law found me while I was masturbating because I couldn't stand it.
