[M]y [F]iance cheated, and I ended up with her sister

This happened a few years ago. But let me give some back story.

Back in 2010 I met (well call her Sam in this), I was honestly more focused on her sister (Kim). Her sister was chubby and nice big tits and a big ass. But she had a bf. Me and Sam started talking and talking, and before I knew it we were with each other basically everyday. We started dating and a couple years went by. We moved and got engaged and started thinking of starting a family. Shortly after we had decided to try and have a baby. A few months into trying I was told by some mutual friends that she was cheating on me, and that it had been going on for a while, with not only 1 guy, but 3. It didn’t take long for me to find out the truth and when I had found out I called everything off. Kim found out and had been calling me for weeks trying to meet up and chat. Finally I caved and we met for dinner. When I arrived at the restaurant I found her sitting at the table in a very sexy dress. It showed all of her curves and was very tight around her hips and chest. It was low cut and her tits looked like they were on the verge of busting out. Well dinner turned into drinks and before I knew it we were hoping into a cab to her place where I was planning on leaving after I knew she got home safe. Once in the cab she told me how jealous she was that Sam was with me because she had always wanted to be with me, and she knew I always checked her out whenever she was around. I couldn’t help but stare at her tits the whole time she was talking and she knew it but did nothing. A few blocks from her house she told me I should go in and continue the night with her. She reached across the seat and started rubbing my cock through my jeans. Finally we get to her house and I couldn’t wait to get her inside. We barely made it through the door before I had picked her up and carried her to the couch. We started making out and I teased her pussy through her panties for a bit before lifting her legs and pulling her panties down, Revealing the one part of her body I had been dying to see for years. I started eating her out as she was begging for my cock. As I was about to give it to her I asked “what about Sam?” her response was “her fucking loss”. I knew she was on birth control so I didn’t bother putting a condom on. Her pussy was so wet and tight I could’ve came almost instantly, but I paced myself to enjoy what was happening because who knew if it would ever again. The next morning I woke up and my back was slightly burning. I had scratch marks all over my back and dried pussy juices all over my cock. I heard her doorbell ring and woke her to answer because it wasn’t my house. She opens the door and I hear Sam’s voice. Not knowing what to do I quickly got dressed and went and sat on the couch. A few minutes later Sam came in and seen me and asked why I was there. Before I could say anything Kim said “because we’re hooking up” fast forward 5 years, Sam is now my sister in law and auntie to mine and Kim’s daughter…… Karmas a bitch
