Mistress Sophia wanted to control her boyfriend and she felt that the best way to do it was to tame him since she felt that he was too wild. The mistress felt that he needed to know she was not as innocent as he thought she was. That is why she made him walk in on her flirting with and teasing another man. She had the audacity to ask him to sit and watch.
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.
