This mistress was broke and she knew she could make money from this guy. He was proud and he thought he could beat everyone. She was a tough girl skilled in martial arts so she challenged him. They bet some good money that whoever won would take it all. The guy doubled his because he knew he would not lose. But he did not anticipate her vice-like grip which he could not break free from. She choked him with her stranglehold and won all the money.
