My wife's mother, who lives in the next town, came to our house to take care of her and help her because she thought it would be hard for her to be pregnant... One day, when I came home from work, I happened to peek at my wife's mother while she was taking a bath, without any ill intention or intention... Just as I expected, no, even more than I imagined, my wife's mother had a plump, soft, and extremely erotic body. Moreover, my wife was pregnant, so I was naturally living a life of abstinence, so I couldn't help myself...
