Mistress Sophia knew that her boss wanted her and he was making her feel uncomfortable. She wanted a raise as well but he did not want to give it to her until she slept with him. So she got pissed and she cuckolded him and told him that if she ever slept with him, it would be because she wanted to and not because she needed a raise because that was her entitlement given the kind of work she did and how she delivered.
Mistress Sophia was not pleased with how her husband questioned her all the time and how he rarely did what she asked him to do. She did not want that to be the modus operandi in their house so she had to do something about it. After careful consideration, she chose to cuckold him so as to make him realize she meant business and would not tolerate his behavior again.
