A single mother is proud of her son. However, he has no feminine side and occasionally touches her body while she is sleeping. Nothing more happens, so Kaori tries not to pay it any attention. One day, she takes a long weekend and goes on a trip to a hot spring with her son. While on the trip, her son suddenly confesses, "I love you as a woman." She initially refuses, saying that it is not right for a mother and son to do this, but she gives in to her son's enthusiasm and gives in, saying that it will be just for today. Feeling the pleasure of a woman for the first time in a long time, Kaori transforms from a mother into a woman. This is an incest story in which their twisted love opens the door to a forbidden relationship after repeated encounters.
