When my wife was hospitalized to give birth, my mother-in-law came to Tokyo from the countryside. It seems she was worried about her daughter after the birth and how my life was going. I started living alone with my mother-in-law. She changed in front of me, and I became aroused by her thin clothes and defenselessness. The son-in-law exposed himself to his mother-in-law, but she said she understood and said, "What a stupid thing to say. You're going to be a father. Right now, Kokoro can't keep up. Just for today..." and allowed herself to be with her.
