Chieri didn't think sex was very pleasant, perhaps because her school boyfriend was bad at it. After graduating, she got a job at a real estate company. The manager there took a Ke'ai to her, and before she knew it, they were having a physical relationship. The manager was quite a sadist, so Chieri naturally became aware of her own masochistic nature. Her body learned to feel pleasure that she had never felt as a student. Her affair with the manager ended quickly. After an arranged marriage, she married her current husband, but was dissatisfied with the sex that was too normal. One day, she met the manager again. She wanted to have sex right away, but she was not feeling well, so she was introduced to an older man.
