One of two stories, depending on my mood.
One could be when she was convinced by a stripper to get topless on stage in front of a group of her male friends. She's busty petite, with some of the best tits on the planet. Lucky guys.
Second is a story that's only hot to me if I am stupidly horny, but when I am, it drives me crazy to think about. It's less a story and more an idea, because I don't know much of the story. But one night at a party, she decided to give in to flirting from a guy who everyone knew was massively hung. She had a boyfriend and he had a girlfriend, but he constantly cheated and the girlfriend never left. Anyway, somehow, some time that night, she fucked him, and she proved to be one of the few who could take a pounding from his roughly 10x6.75 inches. So they became a recurring thing, and it's just so hot to think of how she was in her absolute prime but still allowed herself to be just used as this monster cock's plaything for a few years in college.
