I'm a husband who's cheating on his wife with his sister

I'm a husband who's cheating on his wife with his sister<br><br>I want to keep anon because I'm ashamed of what I've done. <br><br>My wife and I are married for two and half years, and we have a daughter aged one and a half. My sister is a year older than me and is single. I had a very normal relationship with my sister until she had her first boyfriend when I was 16. It was as if she became uncomfortable around me and started to avoid me. I figured it was probably because she had a boyfriend and was no longer focused on family. I never thought much of it and our relationship never really improved. She had a few more relationships afterwards but never told me anything about them. I also kept my relationships private and so neither of us were really open with each other about our relationships. <br><br>This is where the problem starts. Last year, my wife's friends and family had a party and invited me, my wife and our daughter. My sister was in town so I invited her too. I didn't think much of it and thought she would have a good time with my extended family. I didn't prepare her at all for the party and didn't tell her she was invited at the last minute. As a result, she overdosed on her drink and was very drunk. Throughout the night she started getting more and more interested in me, and eventually tried to kiss me outside when I was smoking. I'm ashamed to admit this, but I felt an intense attraction to her at the time and was really turned on. I pushed her away and told her to go home. She insisted we share a taxi together and so I had to take her home. We ended up having sex and I told her to pretend like nothing happened. She asked if I told my wife but I said no. I told her it never happened and to get over it. I was really cold and distant with her and she left in tears. <br><br>A few weeks after, my wife and I got into an argument and my wife said that she needed space. I told her I was going to my sister's to stay there for the night. She said I was allowed but she wanted me to come back tomorrow. So I packed my stuff and left, but instead of going to my sister's house, I drove to hers where I stayed the night. We had sex again and she said it was much better this time. I agreed with her and said I couldn't control myself. I said that I wanted to make it feel even better and she agreed. We went on making each other happy for the rest of that night. <br><br>That night started off our affair. The next day, I went back home and acted like nothing was wrong. My wife was much more friendly to me and I could tell she was making a big effort to make up for the argument. I was really upset by this because I knew I was being a coward and lying to her, but I couldn't resist the guilt trips my sister used on me. She said that she was lonely and I was the only guy who could satisfy her. She said I was her soulmate and that she needed me. <br><br>At this point, I was still making love to my wife and our sex life was great. But whenever I was at my sister's house, I would just let myself lose control to her. We had sex whenever I was at her house and she would always just look at me sultrily and make seductive movements. It made me feel like I owned her and was in a position of power over her, and sometimes she would even call me daddy and act like a little girl. It really turned me on. <br><br>As time went on, my wife noticed that something was up. I started spending more and more time with my sister and started distancing myself emotionally from my wife. My wife was really confused because I still had sex with her and she didn't know what was wrong with me. I tried to reassure her and told her that it was just a phase. I said I was doing fine but my wife was still convinced that there was a problem. She said that she needed me and couldn't focus on work without me. I told her I was fine and that our relationship was working. My sister was getting more upset as time went on and sometimes she would say "I'm your wife and not her". I tried to reassure her but I could see that she was desperate for me. <br><br>I was living a double life, and I was conflicted about what was happening. It was like I was living two lives, and I didn't know which one was actually true. My wife was more than happy to have me and my family was happy for me, and everyone around me was happy. It was as if I had a normal life, but I had a whole different life at my sister's house. <br><br>In the end, I had to choose between my sister and wife. It was a painful decision, but I decided to end my marriage and affair with my sister. I moved out of home and into my sister's house, and started our relationship. It's been a few years now, but I still don't regret my decision. My sister is the love of my life and I couldn't be happier with her.
