The stunning Mistresses An Li and Annalisa caught their slave masturbating without permission so decide to lock him into long term chastity. To prepare for this he will experience teasing and edging over and over, as they tie his balls tightly, chastising and humiliating his small hard cock. They use the Venus2000 to bring him close as they Mistresses take turns sitting on his face and controlling his breathing, the more he takes the faster the milking machine. Finally he gets a vibrator assisted handjob, his cock released just before he cums, resulting in an amazing, frustrating and cruel ruined orgasm. His cock finally going limp to allow them to lock his errant dick away forever.
