FERA-151 Thought it would be okay to have sex just once... but ended up being made to cum repeatedly by her son, the mother Yurika Hiyamayuri fell into a quagmire.

I was pushed down by my son. I'm no match for him in strength. Even if I scold and try to calm him, my words don't reach my son who is in a state of excitement. Feeling threatened, Yuri-ka reluctantly agreed on the condition that it would be 'just this once.' I thought that if I made him pull out and calm down, he would understand that this relationship is unacceptable. But my son, having tasted the flavor of my mature body, became even more uncontrollable. And Yuri-ka herself also fell into the abyss of forbidden pleasure.
