Isabella has the perfect requirements for giving a good and intensive facemASSage: her soft and fleshy ASS and enough weight for a nice mASSage-pressure.
The slave is waiting on the bench for his treatement, Isabella steps over him and decends her ASS reverse on his face.
After a short but intense reverse "ass eating the face", she turns around to foreward and the to sideward facesitting and rubbing.
He's groaning, but i think he had his pleasure... if not, who cares!
