In the heart of a bustling city, he unzips and pulls out his throbbing cock, stroking it shamelessly as unsuspecting passersby brush past. The risk of being caught only fuels his desire, his balls tightening as he nears release. With a final, furtive glance around, he cums hard, leaving his mark on the city sidewalk.
