Wife of wife and forbidden sex

It is Toru that the wife of the wife passed away, and the mother-in-law was married alone if it was lonely. One day, Toru, who had accidentally witnessed the appearance of her mother-in-law masturbation, was excited more than sex with his wife, pushed down and committed it. The mother-in-law who has lost the feeling of pleasure after a long time and received the Po of Po has begun to say that "Toru" and "my daughter help me" when I heard that Toru and daughter did not work well at night.
