OFKU-177 "The mother of my wife's fellatio 'We're not related by blood, so it's okay if you just put your dick in my mouth, right?'"

Because my wife was hospitalized, my mother-in-law suddenly helped me from my wife's parents' house. As usual, my mother-in-law does housework as quickly as possible, not only taking a bath, but also having a drink with me at night, and at least rubbing my back as a filial piety. It's like I'm conscious of her mother-in-law while looking at her unsuspecting mother-in-law. That night, maybe because I didn't have a wife, I finally couldn't stand it anymore...
