After retiring from teaching, my father spends his days in a daze without any particular hobbies. My wife, Yuri, was taking care of my elderly father during the day. One spring, when I came home from her work, I saw her wife's ass submissively sucking her father's cock in the bathroom. I was so shocked that I hadn't said anything to them since that night, but after a while, I heard that her wife was happy.
