Melissa's heels click on the worn asphalt as she sways her hips, putting on a show for the unknown watcher. The scent of distant rain and her own perfume fill her nostrils as the stranger's hands grip her ass, lifting her onto a nearby dumpster. The metal is cold against her skin, a stark contrast to the heat radiating from her body. She gasps as he unzips his pants, revealing his throbbing cock. He's big, bigger than she expected, and she licks her lips in anticipation. He pushes into her, stretching her, filling her completely. She cries out, her nails digging into his shoulders as he begins to move, his hips slapping against hers, the sound of their bodies meeting echoing in the empty alley.
