In the throes of a heated workout, Gamma Cassiopeiae can't resist the temptation to stroke his throbbing gym dick. He drops his towel, revealing his thick, veiny cock, and starts jerking off. His muscular form glistens with sweat as he picks up the pace, his ass clenching with each pump. The room fills with the sound of his heavy breathing and the wet slapping of his hand against his cock. He grunts, his body tensing as he nears orgasm, before finally spewing his load across the gym floor.
