The slave calls Mistress Julia to come to the studio and film with her as he has not been milked for two weeks. Julia does not really want to film but agrees if it will be a fast one. S he takes off her jeans and exposes her fishnet stockings. For the filming she has choosen her golden GML stilettos…..it will not take long for him to cum under them. She steps on the box, massages his continously and the slave cums. She then leaves and puts her jeans back on. The slave begs her to do it again and she agrees – but it has to be her way. She puts the shoes back on and proceeds to empty the ashtray over the cock. Soon the box and cock are black. His pre-cum doesn?t help to lubricate her soles instead they feel like sanding paper. She now does everything painfull she can think of including some long and deep cock spiking. He is still hard so she stands on him until he cums again. But she does not get off and does some post orgasm trampling over the cock. Finally she steps off and the cum spills out.
