Married for four years, Shinzo is a housewife. One day, her husband brought his young subordinate Shoji home. Since the last train had left, he had to stay over, and when he opened the toilet door, he saw Shinzo in her underwear. 'I'm being watched... I want to tease this seemingly innocent guy...' Shoji couldn't hold back his desires and that night, invaded her futon seeking her body. From that day forward, in the intimate space close to her husband, they fell into a sweaty sex life together.
