Jefferson, a muscular black man, sought respite in the river, but his libido had other plans. As he waded in, his massive cock twitched, tenting his tight, wet underwear. He couldn't help but grasp it, his big, meaty hand working his length as he panted, his eyes closed against the sun's glare. The water lapped against his round ass, and he moaned, his body tensing as he came, his cum clouding the water around him. He emerged, his chest heaving, his body glistening with sweat and river water.
