Mistress BlackDiamoond was not happy to learn that her slave had not been doing what she had been asking him to do. She had never asked for a progress report. But today she did and it caught him flatfooted. He had no answer and the mistress ass smothered him as punishment. She wanted to make sure he had learned his lesson and learned it the hard way. She choked him and had him jerk off at the same time she was choking him.
