In the dimly lit lair, a caped crusader, sans the crime-fighting gear, dons only his Batman mask. His hand strokes his throbbing cock, the mask's eyeholes framing his intense gaze. Pre-cum glistens on his helmet, a testament to his growing excitement. His grunts echo in the empty space as he jerks faster, feeling his balls tighten. With a final, deep groan, he unleashes a massive load, coating his mask in sticky, warm cum.
