Carmen Rivera, the sultry dominatrix, leads a naked workout, her toned body glistening with sweat as she commands her submissive to follow suit. She begins with sit-ups, her firm breasts bouncing, then moves to squats, her ass flexing. As her sub struggles to keep up, Carmen grows frustrated and decides to torment her. She orders the sub onto all fours, then roughly fingers her pussy, twisting and stretching her tight hole. The sub moans in pleasure-pain as Carmen's fist disappears inside her, fucking her mercilessly.
