I watch as his hand, adorned with a watch, inches closer to her thong, his fingers brushing the waistband, ready to pull it down. My wife’s ass, round and jiggly, is on full display, her back to me, her face turned away. She’s a vision of temptation, her curvy body accentuated by the sheer white thong that barely covers her. The black bra strap on her shoulder is a stark contrast to her light skin, and her long, straight brown hair with blonde highlights cascades down her back. I can almost hear her voice, whispering the details of their previous encounter, as I stand there, a cuckold, waiting for my turn to be used.
