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.

"Just this once..." No matter how much she scolded or gently persuaded, her excited son wouldn't listen. She couldn't match his strength. Emiiko resigned herself and decided to accept her son's desires. This would be a one-time mistake. She told herself to forget it quickly and return to normal life. But contrary to her feelings, her body reacted strongly to her son's thrusts. Against her will, she climaxed repeatedly, showing her son her lewd, feminine true self.
