Due to work, I was sent to a rural area where my brother lives for several months. As a result, I ended up staying at my brother's place. My sister-in-law, Rieko, is a gentle woman, and I had feelings for her. However, we only met a few times a year, so I was always nervous around her. But because of my shift schedule, which had me working nights, I inevitably found myself talking to Rieko more often. I'm not much of a talker, so I mostly just listened to her stories—recent events, neighborhood gossip, complaints about my brother, and sometimes even details about their intimate life, making me wonder if she was unsatisfied. One night, after finishing a late shift and taking the last train home, I saw Rieko moving around in the dark room. I tried to leave without being noticed, but she spotted me, creating an awkward atmosphere. Later, Rieko came to my room. I promised to keep it a secret, but in my panic, I confessed my feelings for her and hugged her. Confused, she offered an exchange: let me do what I wanted, then closed her eyes. Slowly, I kissed her. My long-suppressed rationality shattered, and I kept taking her all night...
