The wife, a bikini-clad bombshell, struts her stuff on the treadmill, hips swaying, ass cheeks jiggling in her skimpy bottoms. Her husband, hidden in the shadows, watches, his cock twitching at the sight of her toned body and the thin string of her dental floss bikini bottoms disappearing between her ass cheeks. He can't help but imagine that string snapping, her pussy exposed, ripe for the taking.
