The air is thick with anticipation as he closes the door behind him, locking out the world and all its distractions. He leans against the cool wall, his heart pounding in his chest as he unzips his pants, his hard cock springing free. He wraps his hand around it, feeling the heat, the pulse, the smooth skin. His strokes are slow at first, building a steady pace, his body tensing and releasing in time with his movements. His mind is a blank canvas, filled only with the sensation of his hand on his cock, the promise of release growing closer with each stroke.
