With a mischievous glint in his eye, a young man steps out into the busy city streets, his intention clear. He spots a quiet corner, yet one with a clear view of passersby. Unbuttoning his jeans, he reveals his stiffening cock, the cool air causing it to throb. He begins to stroke, his eyes locked onto the unsuspecting public. As his arousal grows, he leans down, his tongue flicking out to lick the pre-cum beading at the tip. He takes his cock into his mouth, his lips stretching to accommodate his girth, his hand working his shaft in tandem with his eager mouth. The thrill of being watched, of being so close to discovery, pushes him to the edge. He pulls back, his cock pulsing as he cums, his load splattering onto the concrete, a secret message for the unsuspecting public to discover.
