There's something thrilling and exciting about doing something you know you're not supposed to do. Like cheating on your wife. Or your husband. It's not that you don't love them. It's more about wanting something different from time to time. Deep down you know that if anyone ever found out you suck cock, or take it up the ass, you could lose everything...your spouse, your home, your kids. And yet, the thrill of getting caught is exactly what makes cheating such a titillating experience.
