In a private, dimly lit room, a black bull prepares for a solo session, his cock already hard and eager. Slipping on a cock ring, he admires his engorged, veiny length in the mirror. He lubes up, his large hands expertly teasing every inch of his meaty tool. With each stroke, the ring emphasizes his thick, pulsing vein, driving him closer to the edge. He grunts, his muscles tensing as he fights the urge to explode, prolonging his delicious torment.
