A son raised single-handedly by his mother, but he had no interest in women and sometimes she would touch his face while he was sleeping. She tried not to mind it. One day, they took a long weekend and went on a hot spring trip together. During the trip, her son suddenly confessed, 'I like you... as a woman.' Although she initially refused, she eventually gave in to his passion, thinking 'just for today...' and let him have his way. The long-forgotten pleasure of being a woman transformed her from mother to lover. After multiple encounters, their twisted affection opened the door to taboo incest.
