Dave's cock, a sight to behold, stands erect and proud, begging for attention. The tip glistens with pre-cum, a testament to his growing arousal. He teases the sensitive skin with his fingertips, tracing the veins that pulse with desire. His cock twitches in anticipation, yearning for more. Dave, lost in his own world, begins to stroke himself, his grip firm and steady. His cock grows harder, the head turning a deep shade of purple, as he brings himself closer to the edge. The room echoes with the sound of his pleasure, a symphony of flesh meeting flesh.
