Lady Stefanie wished that she had known about chastity devices and chastity femdom earlier because she would have ensured no one ever cheated on her. She made her husband wear a dick lock in the morning before he went to the office and she kept the key. She opened it in the evening when he got home and that way, the mistress made sure he would not cheat on her.
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.
