I couldn't believe my luck, and I couldn't believe that between us, my wife and her husband was the thin wall of a room, with a fully open door and here we were, fucking each other, as if we were alone in the house.
This girl was centrefold material, whereas, I was just an average looking guy who in his wildest dreams, would never have expected such an event.
God it was so hot being inside her, feeling her incredible body, fucking her, and in complete silence, save for a muffled moan or sigh. The feel of her butt cheeks against my stomach, Mmmm there's nothing like the feel of a woman's butt against your bare flesh, my cock, sliding in and out of her, as I felt and viewed, all of her completely naked body.
