Madame Marissa had planned her boss' punishment meticulously. He was a proud man and she knew he had a thing for her. He wanted to fuck her and she did not agree to it. As she quit, she had come with another man to his office and she fucked him after she had tied her boss to a chair and forced him to watch as another guy got what he wanted but could never get.
When madame Marissa noticed that her boss was only interested in using her and not doing what they had agreed on, she knew it was time for her to do something about it. The mistress teased him and got him where she wanted him. Then the mistress got him cuckolded and he could not believe it. She was targeting his fragile ego and she shattered it to pieces with what she did.
