Shinichi, who has a wife, was aware of his mother Eri as a woman every day. One day, unable to suppress his overflowing sexual desire, he decided to go on a hot spring trip with his mother. Love between parent and child… Eri had thought her son's words were a joke, but when she saw the penis she hadn't seen in a long time, she surrendered her body to the waves of pleasure. She received her son's hot semen deep inside her, unable to resist the intense pleasure. In the hot spring deep in the mountains, echoes of forbidden moans resonate in this tale of mother-son incest.
