Asian Dominatrix DominaFire commands her submissive slave, Df Boytoy, into a medical exam room, her eyes gleaming with sadistic intent. She begins with a firm, clinical handjob, her long, red nails digging into his flesh as she edges him towards orgasm, only to deny him at the brink. DominaFire then introduces a urethral sound, the cold metal glinting under the harsh lights. She teases his sensitive urethra, causing him to squirm and moan, his cock throbbing with a mix of pleasure and pain. Mizzi Red assists, her eyes locked onto the slave's tormented face, as DominaFire gradually inserts the sound deeper, her sadistic pleasure evident.
