My mother-in-law, Kana, came to Tokyo half a month ago to support her pregnant wife. I thought her housework would be easier and her wife would be in a better mood because of her Kana-san, but her wind was more than before, and she was angry at me who comforted herself alone. I was sentenced to a masturbation ban. A few days later, she said that Kana, who had heard our quarrel that she was in agony because her libido hadn't subsided, would replace her. I was on the verge of overflowing her sexual desire, and I made an excuse only once and asked for Kana-san.
