Carmen Rivera, the epitome of female dominance, stands over her trembling captive. She adorns her hand with a sleek, black glove, her eyes gleaming with sadistic intent. "You will take my fist, my pet," she purrs, pushing him down onto the cold, hard floor. She roughly grabs his hips, positioning him for her invasion. With a swift, powerful thrust, she buries her fist deep within him, evoking a guttural groan. She brutalizes him with her fist, each thrust harder than the last, until he's a quivering, pleading mess, desperate for her mercy.
