This guy had pissed off mistress Jardena and being the kind of girl she is, she knew she had to get even with him. And her way of getting even with him was to make him drink her pee and that is why she chose to do it. The mistress did not care how humiliated or degraded he was. In fact she felt that the more humiliated or degraded he was the better.
Mistress Jardena went for a date with this guy but he disappointed her as he was the worst guy she had ever been on a date with. She had to punish him for wasting her time and for being a loser. She peed on him to humiliate him and to degrade him at the same time. He did not know she felt that way about her and he had to apologize.
Mistress Jardena did not like how careless this guy drove. He nearly hit her and she did not like to imagine what would have happened had she not been more alert. So she punished him after following him to where he stopped. She turned him into a human toilet and she got him to drink her urine. He could not say no and had to endure the humiliation and degradation.
