Her slave has not been milked in a long time and Mistress Summer is in the mood to allow him cum. Of course, because he is a slave, she will not allow him to cum in any normal or dignified way. Instead she will drain his balls mechanically. He is bound in the milking chair with his cock exposed and ready for the milking machine. She feeds his hard cock into the fake orifice and starts the piston pumping, telling her slave he better not cum too fast. It is fun for her to see him try to hold back his load as she speeds up the piston, and even more fun to see his desperation when she slows it down to a crawl as he nears orgasm. Before too long she allows her slave to have his orgasm, but Summers fun with him is far from over. She never tires of tormenting her slave as she feeds him his own cum load before getting ready to put his cock back in the machine for the entire night.
