I am in love with my brother’s stepdaughter. My brother married my sister-in-law, who had a daughter from her previous marriage. I lived with my senior brother (58 years old) before I started working and got my own place. Before I left, my brother’s stepdaughter (LOML) and I were having sex for almost a decade. She was 20 when it started, and I was 26. My mom always knew but warned me that she didn’t want any issues. My brother had his suspicions because I told him just last month, and he wasn’t surprised. The problem is his wife. He said he doesn’t know how she will react, and we will meet at the end of this month to tell her that we will be getting married. She’s scared, and I am scared. My brother is even more scared, and my mom will be there too.
