In the cramped shower stall, the jock's big cock tents his towel. He can't hide his excitement any longer. He drops the towel, his thick, pulsing dick standing at attention. He grabs it, stroking from base to tip, feeling the slick pre-cum lubricate his hand. He leans against the wall, his breath coming in ragged gasps, his ass clenching as he nears the edge. With a final, desperate stroke, he comes, his hot cum splashing onto the shower floor.
