Knocken, clad in leather and denim, parks his motorcycle in a bustling city square. His heart races, not just from the ride, but from the taboo he's about to indulge in. He unzips his pants, revealing his stiffening cock. He starts slow, teasing himself, as passersby unknowingly provide an audience. His strokes quicken, his breath hitches, and his grip tightens. A car horn blares, jolting him, but it only drives him closer. With a final, forceful stroke, he comes undone, his cock pulsing as it coats the bike's seat with his hot, sticky cum.
