After divorcing her husband, she raised her son alone. Her son, who had become a semi-hikikomori due to relationship troubles, was taken on a hot spring trip. She didn't want to see her child suffering... she wanted to heal him somehow. Her love for her son transformed into forbidden love. Just encouraging her son... she thought, but she was swallowed by female pleasure. In a small inn deep in the mountains, they repeatedly entwined and reached climax after climax. Before she knew it, they were seeking each other out in this taboo tale of incest.
