Mariah has the biggest juiciest ass ever. She knows how much it smothers her slaves face. What will make him more on edge in his chastity is rubbing her pussy on his face til she cums. Then he will feel how wet she is and it will make him even weaker for her! Feeling her wet pussy on his face without being able to touch his dick or ever put it in her pussy makes him go crazy. Mariah really loves humping his face but hates when he moves or breathes because it loses her concentration. He just needs to sit there and shut up. After all, he is so lucky to even be in her presence.
