Mistress Sue wanted to find out her slave's pain threshold so she humiliated him and tortured him. She teased him with her big and sexy tits and when he lost focus, she strangled him with her hands. She sat on him and she made sure he could not breathe properly and besides that, that he was in a lot of pain. When she was done with him, she slapped him and sent him away.
This mistress was tired of how this guy was a bother to other members of the gym. She did not like his attitude and had to talk to him about it but he was rude and did not change even a little. Today he was something else so she called him to her office where she surprised him with a stranglehold he could not break free of. She also leg scissored him and tortured him till he agreed never to disturb anyone again.
