FERA-140 Thinking it would be okay just this once... but ended up being made to cum repeatedly by her son, the mother, Sugioka Emiko, fell into a quagmire.

"Because it's only once..." Even if I scold him or tell him gently, he doesn't reach my excited son's ears. He can't compete with his physical strength.

However, contrary to her feelings, her body reacts violently to her son's piston. Emiko shows her son the real face of a lewd female.
