Yumi, the mother-in-law, came to mediate a quarrel between her husband and wife that started over a trivial matter. Even though Yumi is my mother-in-law, she is beautiful and elegant. She is exactly what I would call a lady. Unlike my wife who is always dissatisfied and complains, her kindness makes me want to be pampered. Yumi is staying at my house tonight. And I accidentally saw Yumi naked. My crotch fluttered as I watched her desperately hide her body and look ashamed.
