Mistress Gaia did not want to deal with a malicious person and when this guy turned out to be one, she felt that she was not in the mood to deal with him and she had to humiliate as well as dominate him so that he learned never to be malicious ever again. That is why she made sure she turned him into a human pony and rode him to both humiliate him and to make him feel pain.
Mistress Gaia wanted to show this slave that it was in his best interest to make sure he did things her way so as to avoid being punished. He had taken what she told him for granted but today he took her seriously when she tied him up and she used him as a human pony. She was on his back for hours and he collapsed with exhaustion as he could not support her any longer.
Mistress Gaia wanted to try anything and everything about pony riding and pony play fetish and she did it on her human pony. She was least bothered about the pain she was inflicting on the human-horse and more concerned with the fun she was about to have. And that is all that mattered to her. She had a great time but the same cannot be said of the human pony.
Mistress Gaia wanted to teach this guy a lesson that he had never been taught before. The mistress wanted to change his laziness and she did so with her pony play mistress. The mistress rode him for a bit and she noticed he was tired and could not go on. So she changed tact and she whipped him as painfully as she could. He learned his lesson the hard way.
When this guy tried to con mistress Gaia, he did not know that he had gotten himself into deep shit. No one messed with mistress Gaia's money and got away with it. She punished him cruelly by stripping him naked and whipping his balls. She did not spare his dick either and she enjoyed how he cried and begged her to stop. She stopped and turned him into a human pony which was also painful as she rode him for a long time.
Mistress Gaia had been told by her friends about how great pony play was. She had to try it for herself and when she did, she was blown away by how great it was. She loved everything that happened and she whipped him and did everything that she had heard her friends say they loved and it was exhilarating for her but it was absolute torture for the slave and human pony.
This guy was a bully and had been warned to stop his bullying but he did not stop. Mistress Gaia was fed up of him and she chose to do something about it. She tricked him to go to her house and she turned him into a human pony. She whipped him while naked and she forced him to carry her even when he felt his back was breaking. Needless to say, he never bullied anyone again.
Mistress Gaia wanted to teach her slave a lesson. So she punished him in a way he did not expect. She used her pony play fetish to do it. He expected a different punishment but he did not get it. She even whipped him when he slowed down. She got him to lick the soles of her boots and she also made him behave like a pony before she was done with him.
Mistress Gaia was tired but she had to punish her slave. She chose to do it differently. She chose to ride him like a pony and she cruelly did so. She forced him to carry her around. Being heavy, he was at pains to do it but she had a whip ready which she used when he slowed down. She had fun doing it and it was an effective punishment too.
Mistress Gaia wanted to send this guy to enemy territory. She knew he was going to be tortured and humiliated but she wanted to do it first so that when he went, he would always be ready for whatever was thrown his way. So she whipped, trampled and crushed her slave for fun. She also rode him like her human pony before she felt it was enough punishment for him. She toughened him up so that he would be able to carry out her mission.
