I ended up staying at my brother's house for about a week due to work. My sister-in-law, Yuka-san, is very beautiful and kind. I haven't seen my sister-in-law much since my brother's wedding. She had some peculiar habits. When no one was home, she was always naked... Yes, she was a nudist. I never imagined that knowing this would lead my sister-in-law and me to such a situation.
