I'm staying at my brother's house because of work. My brother and I have different lifestyle rhythms, so we don't see each other much, but my sister-in-law, Minami-san, is very kind to me, so I was excited every day. That's no wonder, since I was delusional that I would be such a wonderful wife ever since I was introduced to my older brother, Minami-san. One day when my work schedule changed and I came home, Mr. Minami was masturbating alone while watching erotic videos. I tried to leave quietly, but Minami noticed me. When I ran into my room, Minami came. I nodded when asked if I had seen it. I was told that I despise you, and I shook my head. And I was so nervous that I confessed that I liked Minami. Then, Minami-san, will you keep what you saw a while ago a secret? I heard. I nodded, of course, and instead of keeping it a secret, he gently closed his eyes and brought his lips closer to me...
