Professor Dotadu, a gym enthusiast, starts his workout in a sleeveless singlet and shorts, his tattooed arms rippling with each movement. He performs squats, lunges, and push-ups, his body becoming slick with sweat. His hands roam, caressing his bulging crotch, his breath hitching as he feels himself grow harder. He moves to the bench, lying back, his hand slipping inside his shorts to grip his cock. He strokes slowly, his hips bucking, his moans echoing in the empty gym. His body tenses, and he cums, his load spilling out, marking the gym floor.
