My mother in law, Kana, is always on my side when I fight with my wife. She looks so young and has such a nice figure that it's hard to believe she's my mother in law, and I couldn't help but stare at her ample chest and big ass. One night, when I was secretly masturbating after my wife had gone to sleep, Kana came into my room without knocking... Perhaps she took pity on me, and asked, "Shall I... do it with my hand?", giving me a handjob. After that, Kana became curious about my big cock, and I continued to have her give me handjobs, but I couldn't resist the sex appeal she exuded... We wanted each other's bodies, and we started having creampie sex behind my wife's back, spending all our time together. *This work is a spin-off of "Tired of the daily marital quarrels, I took advantage of my mother in law's kindness and came inside her over and over again..." This is an excerpt from "Kana Morisawa" (product number: dvaj00618).
