You didn't mean for it to happen. You've always sneered at people who spend all their time on the prowl, obsessing about that one true fit. Besides, you already have another in your life, who's always been faithful and comfortable. You're not even looking.
But sometimes it happens. A new love catches your eye and suddenly you realize what you were missing--what suddenly, heart-wrenchingly, you can no longer live without. A new love that cups your derriere lovingly, just the way you like it, and whispers how hot you are. The fit, the timing, everything is perfect, and you are more tempted than you've ever been before. You tell yourself that it's not right, that you're happy as you are, you can't afford this new commitment--what will you tell your spouse? But it's inevitable, really.
Sooner or later you're going to buy that new pair of jeans.
$24.99, baby. I don't even feel cheap.
