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.
