since my wife got pregnant, my wife and I have been fighting every day. whenever that happens, Yukari-san always takes my side. Yukari-san is so youthful and has a good figure that you wouldn't think she's my mother-in-law. perhaps because i was frustrated from my wife's pregnancy, i can't help but follow her breasts and ass with my eyes. one night, while masturbating, she came in behind me without knocking... her devoted hip movements are different from my wife's and are irresistible! i want to fuck her repeatedly, even though my father-in-law is a lesbian! even after making up with my wife, i can't resist the charm of her big ass and can't stop having a secret affair! ahhh~~ i want to keep doing erotic things with my mother-in-law forever!!
