Handsome, tattooed twink Justin, fresh from a vigorous workout, decides to relieve himself in his tight, sweat-soaked underwear. As the warm stream flows, he feels an unexpected surge of arousal. He quickly strips off his wet briefs, revealing his already stiff, massive cock. He strokes his length, his eyes glazing over as he remembers the sensation of his hot piss soaking his crotch. His hand moves faster, his breathing heavier, until he can't hold back any longer. He lets out a guttural moan as his cum shoots out, coating his abs and the floor.
