Many years ago she went out with some friends for drinks. She came home at 1am and was drunk. I started feeling her up and she smelled like alcohol, sweat and after shave. I asked her if she had fun and she said she did. I attempted cunnilingus but was not allowed. My face got to her belly button. I was oblivious but now know I was smelling a combination of her pussy and semen. She allowed penetration and as I fucked her a smell of dirty pussy was very present. She was very loose feeling and wet and sloppy. I asked her if she was hit on and she said yes she was. I pressed for details and she told me to "hurry up and finish". I told her it would help if she told me how she fucked another guy tonight. She proceeded to tell me about a black guy who hit on her and she went out to her car and let him fuck her in the backseat of the car in the bar parking lot. She told me I needed to hurry up and cum because his big cock made her sore. I exploded quickly. I now know that the entire story was true. I also knew that night that she had been fucked. The next morning I got her panties out of the laundry and found them full of dried cum. I sniffed them and jacked off in them. It took years before I knew any details. After that night she was often very wet. She explained that she was getting wetter and that her chemistry had changed. Truth was she only let me fuck her on days where another guy had already been inside her. I was only allowed to penetrate when she knew that I was inside her getting sloppy seconds. It eventually evolved in to her having me eat her after she had been filled by another guy. It makes me hard to this day.
