Mistress Dana wanted to make sure that this guy learned his lesson and so she set out to dominate as well as degrade him and she did it with her hot ass. The poor guy had to endure being forced to lick her ass as well as being choked by the guy. The mistress made sure that the guy learned not to piss her off again and he learned after what she did to him.
Princess Serena does not have a slave but she wanted to facesit on this loser and humiliate him. He had not messed up but she still wanted to facesit on him. The mistress, being hot, teased him and he could not resist her. As he got turned on, he was like putty in her hands and she got him to do all she wanted including letting her facesit on him.
