Today, the Dominatrix tied her male slave in a doggy position to a stool - it looked like she wanted to milk a cow. But the reason was clear: she wanted full access to his cock, balls, and ass without giving him any possibility of resisting. Next, she inserted his cock into a vacuum penis pump. This device was tremendous, as it sucked his cock hard, and the vacuum kept it deep inside. While the machine did its work, making his cock bigger and bigger, the Dominatrix started pegging his ass with cock shaped toys. She pushed them deep into his asshole to stimulate his prostate while the automatic device continued to suck his cock. Once the Mistress decided it was enough, she removed the penis pump and attached a vibrating milking machine instead. What happened next was obvious, but her slave came too quickly, which made her angry. Therefore, she left the automatic device attached to his cock after his orgasm and left the room, leaving him behind to suffer.
