In the dimly lit room, a man's hand wraps around his rock-hard cock, the skin taut and sensitive to his touch. He begins to stroke, slowly at first, then with growing urgency. His other hand cups his heavy balls, rolling them gently, feeling their weight. The scent of his precum fills the air, a musky, primal aroma that spurs him on. His strokes become frenzied, his grip tight, until with a final, powerful thrust, he spills his load, his body shuddering with the force of his release.
