At a quiet inn, married woman Maki relaxes both body and mind in a cypress bath. Her husband has been away on a long-term work assignment, leaving them to meet only once every few months, with almost no conversation or intimacy in their daily lives. Soon after arriving at the inn, she finds herself craving the feeling of a man's body again. Her mature form overflows with insatiable desire, seeking sex three times in one night. Her husband eagerly answers her passion, giving in to her every advance. When he asks, "What does adultery mean to you as a wife?" she replies, "Perhaps it's proof that I'm still a woman..."—a response that deeply moves him.
