In the dimly lit room, a lone figure, known only as the Grueso, takes center stage. His massive, uncut cock is the star of the show, and he teases it out from his boxers, letting it hang heavy and low. He runs his strong hands over his muscular body, pausing to tweak his nipples before turning his attention back to his cock. He strokes it expertly, his grip tight and steady, as he inches closer to his climax.
