I had to stay at my brother's house because I was on a business trip for several months to the area where my brother lived due to work.Her older brother's wife, Hitomi, was a gentle woman and I liked her.However, I was nervous because we only met a few times a year.However, due to the shift, the day and night are reversed, so inevitably, I often talk to my sister-in-law Hitomi.I'm not the type to talk much, so I mostly listened to Hitomi-san's story.I heard recent stories, neighborhood things, and complaints about her brother.Occasionally, the story of his life with his brother popped up, and I wondered if he wasn't satisfied.One day, I came home on the last train because of the late-night shift, and I saw Hitomi-san groaning in a pitch-black room.I tried to go to my room, saying that I shouldn't see this, but my girlfriend, Hitomi, found me and made me feel uncomfortable.After that, Hitomi came to my room.I'll keep it a secret, she says, and she's upset.Chitose-san was also confused and closed her eyes that she could do what I wanted in exchange.When I slowly put her lips together, her reasoning that I had endured until now burst out, and I was looking for her again and again until her morning.
