Mistress Deviant had given her slave jerk off instructions and as he did it, he added some swag and naughtiness she did not expect from him and he turned her on. She did not expect for that to happen. And when she gave him cum eating instructions, he did the same and she was wet and wanted to be fucked. But she would not be fucked with him so she went and masturbated in her room.
This mistress wanted to use cum eating to humiliate and punish this guy. That is why she had him jerk off and once he had cum, she asked him to eat his cum according to her instructions. He could not say no to her as he feared what she would do to him next. He had to do it the way she had instructed him. It was a lot of fun for her.
This mistress knows how to get what she wants and today what she wanted was to make this guy jerk off and eat his own cum. When she looked at the guy, he did not look like he was ready for what she wanted to do to him. But she did not care about that. She went straight to what she wanted and she forced him to do it. He ate his own cum after masturbating.
This guy was interested in fucking this mistress but she did not want that. Instead, she charged him for cum eating instructions. She had left out the eating part until he had cum and then she forced him to eat his own cum. He had already paid her and he could not take it back. And she told him it was part of the package so he was forced to eat the cum.
When this mistress realized that she had to punish this guy, she chose to use cum eating because it was the easiest way to humiliate him without inflicting any pain on him. That is why she went out of her way to tease him and dominate him and she was able to get what she wanted. He thought it would go one way but it went a totally different way.
