In college I used to fuck with my best friend's girl behind his back. At the time I was dating the woman who I would end up marrying.
It was grimy and not something I'm proud of but goddamn it was exciting at the time. The three of us used to hang out sometimes and me and his girl would be cracking up to ourselves. Looking back it was pure hate that made me do what I did. Shorty had a nice ass though.
