Sometimes when a lady has a regular session scheduked the other one comes to sit down on a chair while they film and watch. This time Mistress Julia did not only want to watch but warm the slave up for the second lady. She has put on some fishnets and her GML stilettos. While Pearl watches MJ gives the slaves cock a rough work out bringing him close to orgasm several time leaking onto the cockbox. She takes one shoe off and masturbates him even harder. Then she takes both shoes off and stands on the cock fullweight trampling it as if it was a dildo. Now his balls are so tight that it is time to get off the cockbox.
