A little about us first, I was 20 and my girlfriend 18 at the time, we were living in an apartment together and would have small parties almost every week. It was common for things to turn sexual and she would make out with another girl there, sometimes a little more. She had never done anything with a guy aside from me, ever.
Well this night we were playing truth or dare and I went to the kitchen to get some more drinks, after 10 minutes I came back to the living room to find grabbing our friend, Carl's, dick. He wasn't even fully erect but It was already significantly larger then mine on my best days. After a few seconds she let go and we went back to the game. Hours went by and we got more drunk but my girlfriend chose to practically ignore me and laugh among her girlfriends.
After a while one of her friends came up to me and suggested that I could hook up with Allie if I let my girl hook up with Carl. I was drunk and all I thought was how hot Allie was and quickly agreed. The five of us went to my bedroom and I started to fool around with Allie while my girl and Carl did the same right next to us. I watched her squirm while he ate her out and then I watched as he started to fuck her with a dick at least 3 times my size. She squirmed and screamed in ways that I had never seen her do with me before. All this time though Allie was trying to get me hard so we could fuck. No matter what she did though I stayed completely flaccid and about one inch in length. Eventually Allie gave up and left, I just lay there drunk while Carl finished off my girl.
Once he left I got extremely jealous and essentially begged her to fuck me. She was extremely drunk and started riding me but the whole time she was she was insulting me and making it very clear that she was not happy. She went on to describe how good sex with Carl had felt, how she thought about other men when she masturbates and just in degrading things in general.
Over the next 6 months she cheated on me with multiple guys before finally we ended things.
