Mistress BlackDiamoond was tired of using pain to punish and torture her slave. She wanted to use another method. She tied him to avoid resistance and she facesat on him. She attempted to choke him then let him just before he did. She also had a plastic bag over his face and she smoked and blew smoke over it so that she could choke him some more. It was more effective than when she used heels and slaps.
