In order to prevent the slave from struggling Mistress Zora has rolled him up in a carpet. So he lies there helpless so that she can torment him. She needs only his stupid skull for this and she sits down with her hot ass on it. An extensive facesitting session ensues to the slave. Whenever he loses control and runs out of breath panic rises inside of him. That is what Mistress Zora wants. She stays sitting on him and takes away his breath with her ass.
