A dominant mistress takes command, her submissive slave kneeling before her, ready to serve. She presents him with a variety of dildos, each one thicker and more intimidating than the last. He chooses the largest, a massive, veined beast that stretches his jaw wide. She guides it into his mouth, her other hand gripping his hair, controlling his movements. She fucks his face with the toy, her pace increasing as his resistance weakens. She pulls it out, allowing him to gasp for air before pushing it back in, her eyes gleaming with sadistic pleasure.
