Mistress Ava Black was gifted a chastity device by her naughty friends. She had been with it for some time and when she got bored today, she chose to try it. She had to find a loser to wear it so she went out and came back with one. She got the guy to wear it and once it was in place, she teased him and enjoyed as he got hurt when his dick started getting hard.
Mistress Ava had things she wanted from this guy. He refused to give them to her and she was pissed. She could not understand why he was refusing to give them to her so she dominated and punished him for it. She chose to teach him the kind of lesson he would never forget in a hurry. And true enough, he never did it again as he had learned never to mess with her.
