Mistress BlackDiamoond caught her slave telling neighbors her secrets and she was pissed. As punishment, she had him deepthroat a strapon she wore and she also had him bend over and she fucked him in the butt. She cruelly dominated him and she made him learn his lesson through the pain he felt as she did all those cruel things to him. He never told her secrets again because he was afraid of what she would do to him.
Mistress BlackDiamoond is the queen of strapon. She loves using strapons to punish and humiliate slaves because according to her, they are very effective and very efficient. Today she showed her friend how to use it and made her lick it and did to her what she does to slaves so as to demonstrate how she was supposed to use it. The only thing she did not do was stick it up her friend's butt.
Mistress BlackDiamoond likes to use strapons to humiliate her slaves. She knows it is painful and it is their worst nightmare. Her slave had largely avoided getting punished by it but it seems he had forgotten that she had it and when he messed up big time, she got it out and reminded him she had it by making him give it a good blowjob and he nearly choked on it.
