He's alone with his thoughts and his throbbing desire, his fist pumping up and down his thick, veiny shaft. The scent of his musk fills the air, mingling with the faint smell of disinfectant. His abs clench with each stroke, his body tensing as he nears the edge, before finally letting out a deep, satisfied groan, his cum shooting onto the tile floor.
