SPRD-931 Mom, you're way better than that bitch of a wife... Tsukishima Kogiku

It's been a few years since my stepfather passed away. I went to Tokyo to visit my stepmother, who lives in the countryside, for the first time in a long while. My stepmother, Kikuko, had my wife early and is still in her forties. She has a plump, fair complexion, and I've been attracted to her since going to greet her on our wedding. Of course, my wife is also cute, and we have children, so I've been hiding my feelings. When I heard that Kikuko was coming to stay at the house again after many years, I was genuinely happy; just thinking about seeing her again made me excited and kept me awake. My wife isn't very into sex, but Kikuko seems to be hoping for a second child... When I saw Kikuko's underwear in the laundry basket, my rationality vanished, and I couldn't help but smell it. I was frantically stroking my painfully erect penis when Kikuko caught me… She only agreed this one time, but I've become desperate to have sex with Kikuko.
