Kana-san, my mother-in-law, who always takes my side when I fight with my wife. She was so youthful and stylish that I couldn't believe she was my mother-in-law, and I couldn't help but stare at her ample breasts and big ass. One night, after my wife had gone to bed, I was secretly masturbating, and Kana came into the room without knocking. Perhaps feeling sorry for me, she asked, ``Do you want me to use my hands?'' and gave me a hand job. After that, Kana-san became interested in my big dick and had me pull it out with her hands, but I couldn't stand the sexiness that Kana-san gave off...We both wanted to have each other's bodies, stealing my wife's eyes and creampied her. I started to devote myself to sex.
