Lady Scarlet is a clean freak and that is why she did not like it when she noticed that her slave did not observe high standards of cleanliness. She had to do something about it and she used her pee to punish and to humiliate him. Lady Scarlet put a funnel in his mouth and she used it to pee into his mouth. He was shocked but he quickly learned his lesson and that is how he avoided further degradation.
Lady Scarlet wanted to try something new for foreplay and that is why she chose to use her pee to do it. The mistress knew her boyfriend had never experienced that but since he loved how naughty she was and he wanted to experience new things all the time, she chose to surprise him with her pee fetish during foreplay without giving him any warning. She was shocked that he did not complain.
Lady Scarlet wanted to show this loser that she was not going to accept anything short of him doing exactly what she asked. That is why she used her pee to dominate him and to teach him a lesson.

Lady Scarlet was bored and it was reflected in the sort of things she made this loser do. The guy was so into her that he interpreted whatever she was doing to him as spending quality time with her. She asked him to drink her urine and he agreed. To make it more of a challenge for him, the mistress asked him to jerk off while he drank her pee.
Lady Scarlet wanted her slave to taste her urine because she wanted to scare him and so she made him lie down and she undressed and had him drink it. She peed on him instead of making him drink her pee from a bowl or cup. She also wanted to turn him on as he looked at her pussy so he was super confused and conflicted as on one hand, her pussy was on his face but then she was peeing on him.
Lady Scarlet despised this loser. She knew the loser had a thing for her and he did not know how much she despised him. She had wanted to humiliate and to dominate him and she realized that the fact that he had a thing for her was good as she could use it to dominate him. So the mistress teased him and controlled him before she made him drink her urine.
Lady Scarlet was fed up with her boyfriend coming home drunk and she had to find a way to have fun at his expense especially when he came home drunk. Today the mistress used her pee to dominate him and she forced him to drink her urine. The mistress did not care whether he remembered what she had done when he woke up the following morning and he was sober.
