絶倫ヤンデレ母 ～息子の巨根ぶりに貞操がよろめく～

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.
