This time, I met a married woman who said she and her husband are trying to conceive. They've been wanting a child ever since getting married, so they have sex frequently, but they haven't been blessed with a child, and this situation has continued. Moreover, the sex has become mechanical, and she was troubled because she couldn't feel any stimulation or excitement. Then one day, while having lunch with a few female friends, the conversation got lively about playing around with men, and Kotone learned that everyone was having more fun than she had imagined, which sparked her own interest in playing with fire.
