A stern Mistress commands her submissive to his knees, presenting his bound cock. She admires her blood-red stilettos before pressing the sharp heel against his quivering tip. He gasps as she applies pressure, slowly inserting the heel into his urethra. His cock stretches painfully around the invading heel, a sight that makes the Mistress smile. She twists and pushes further, her victim moaning in a mix of agony and ecstasy.
