Bored and curious, I browse Craigslist for a suitable partner to join my wife and me. A muscular stranger, let's call him Mark, responds to my ad. We meet at a seedy motel, my wife dressed in a revealing outfit, her anticipation palpable. Mark is impressed by her beauty, and she eagerly takes his thick cock in her mouth, gagging slightly as he hits the back of her throat. I watch, stroking my own hardness, as she sucks him off while he plays with her big tits. I join in, fingering her wet pussy from behind as she continues to pleasure Mark. We move to the bed, and I slide into her tight cunt while Mark takes her ass for the first time, stretching her with his massive dick. She moans and cries out, loving every inch of our hard cocks in her holes.
