Zetsurin Yandere Haha ~Musuko no Kyokonburi ni Teisou ga Yoromeku~

I, Hazama Mikako, was moaning passionately in my bedroom at night. My husband was away on a business trip and not at home. I consoled myself by telling myself that this was better than having an affair. "Mmm... Mmmmm... Mmmmm... Uhhh..." Just one more thrust of my fingertips and I'd reach climax... Just as I was about to give in to my female desire and plunge my fingertips into her vagina, "Mom...?" The bedroom door opened. Standing in the doorway was my son, Akira. Then I suddenly noticed. There was a large bulge in my son's pants. "Well, then... I'm going back to my room..." "Wait." I suddenly realized that, impulsively, I had called out to my son.
