In the bustling Rio de Janeiro metro, a horny stranger spots a thick, uncut cock straining against tight jeans. Unable to resist, he approaches, discreetly unzipping the unsuspecting commuter's fly and revealing a massive, throbbing member. With a quick glance around, he begins to stroke the pulsating flesh, feeling the vein-ridged shaft grow even harder in his hand. The commuter, too shocked to move, lets out a quiet moan as the stranger's expert touch brings him closer to release.
