When Mistress Katja starts to feel violent, she takes it out on her slave. She calls her best friend and they put her slave on the sofa. They make sure they hurt him with their asses. They bounce on him. They sit on his face. They make sure they leave him breathless. It's a great deal of fun for them to watch him struggle. As soon as they are done, they go out to a bar and leave him sore and bruised.
