I was sent on a business trip to my brother's hometown for a few months, so I ended up staying with him. His wife, Hitomi, was a gentle woman and I liked her. However, I only met her a few times a year, and I was nervous. However, because of the shifts, my day and night shifts were reversed, so I ended up talking to Hitomi a lot. I'm not much of a talker, so I mostly listened to what Hitomi had to say. I listened to her recent stories, what was going on in the neighborhood, and her complaints about my brother. Sometimes she would talk about her sex with my brother, and I wondered if she wasn't satisfied. One day, I came home on the last train because of a late-night shift, and I saw Hitomi fidgeting in the dark room. I thought I shouldn't look at this, so I went to my room, but Hitomi found me, and the atmosphere became awkward. After that, Hitomi came to my room. I told her I'd keep it a secret, and in my panic, I confessed to her that I liked her and hugged her. Chitose was also confused, so she told me that I Ito do whatever I wanted in exchange and closed her eyes. As we slowly kissed, my reason that I had been holding back until then was blown away and I found myself wanting her again and again until the morning...
