John Marsh is in a race against the incoming tide. He falls backwards into the swamp muck, wearing only a thong with a built in cock ring and ball splitter. The thong doesn't actually cover anything in front, so John's cock is naked. He toys with the deep, soft mud then works his way onto his back where he can reveal his muddy cock and stroke it teasingly. The tide comes in before he can finish himself off, but the cock makes a good showing and, after he climbs out, there are some closeup shots of his mud covered, drippy organ.
