In the dimly lit room, a man, unseen but for his silhouette, takes center stage. His uncut cock, massive and veined, throbs with anticipation as he begins his solo performance. He strokes slowly, sensuously, his large hand barely fitting around his girth. The room fills with the sound of his wet, rhythmic movements, and the scent of his pre-cum. His breathing deepens, becoming ragged as he nears his climax. With a final, powerful stroke, he erupts, his hot, sticky seed coating his hand and splattering onto the floor.
