Mistress Nina Hartley enjoys controlling the cocks of her slaves, making them cum on her command. This slave is so under her command that the very sound of her voice makes his cock jump up and down from excitement. While Nina sits on her slaves face, getting her pussy pleasured by his tongue, she completely controls his cock, expertly edging it until it is rock hard, then smacking it back down, denying his orgasm again and again. When Nina has had enough oral worship, she concentrates on jerking her slaves cock, it is just a plaything in her control. When she finally decides to let him cum, she makes sure that he eats his load while she uses her foot to squeeze the last bit of cum out of his cock.
