A full-length POV incest story between siblings. One day, I hugged my sister to comfort her as she cried, and in that moment, she suddenly kissed me. After that, she began acting as if I were her boyfriend. But deep down, I still feel this relationship is wrong. Yet, my body instinctively reacts every time. Once again tonight, she sneaked into my futon. Recently, she's started entering my room and even the bathroom without hesitation, and my self-control is nearing its breaking point. Is continuing this relationship truly right? I'm constantly struggling to confront my own feelings.
