In the empty gym, a lone, shirtless man finds solace in his hands. His body glistens with sweat as he works out, but it's not just his muscles that crave release. He moves to a secluded corner, eyes darting nervously. His hand slips beneath his waistband, grasping his hardening cock. He strokes slowly, building rhythm, as his other hand pinches and teases his nipple. The room echoes with his ragged breaths, each thrust of his hips pushing him closer to the edge. Finally, with a low groan, he spills his load onto the tiled floor, panting and spent.
