Mistress Yuen, a vision in black latex, supervises her ponyboy's training with stern precision. Ushidai, on all fours, is adorned with a bit gag and a tail, his body glistening with sweat. Yuen commands him to lick her boots, her sharp heels clicking on the polished floor. She disciplines him with a swift slap, leaving a red imprint on his skin. Mounting him, she rides him hard, her body swaying rhythmically as she controls his every move, her disciplinarian spirit fully unleashed.
