Mistress Amy had always wanted to ride a pony. But since she lived in a city, she did not have much chance of doing that. She also lived in an apartment. But she had a slave and she chose to use him as her human pony. The mistress had fun riding him and doing all sorts of things to him. He had to endure the pain as there was no alternative.
Mistress Gaia does not like people who take her for a fool. Her slave did and he disappointed her. She did not appreciate being lied to which is what he had done. So she made amends by trampling him, making him lick her heels as well as whipping him while he was naked. She also rode him like a pony before she tied his balls and she ballbusted him painfully.
This mistress loves to do naughty and crazy things. She wanted to ride a horse but she did not have one. So she turned her slave into her human pony and she rode him for fun. She made sure he carried her weight and she did not give him any breathing space. She whipped him when he slowed down and she cruelly tortured him to send a message to him.
Mistress Gaia and her friend found out that this guy was hitting on both of them. They did not like it and they had to make sure he never did that to anyone else. He had to choose who he wanted next time and stick to them only. They lured him to mistress Gaia's house and they whipped his naked butt. The mistresses also rode him like a human pony. He was in pain but he learned his lesson.
Mistress Amy watched her slave for a while and knew she had to punish him if he was to change. She chose to turn him into a human pony as punishment. She forced him to carry her all over the house for a few hours and he was so tired he could no longer carry her. That was when she let him rest for a few minutes then did it again.
Lady Karame knew her slave expected her to slap him or trample him after he had made a mistake. She did not want him to get used to one method of punishment as it would cease to be effective. So she surprised him with a pony play punishment. She undressed him, whipped him and rode him like a pony. She rode him for hours on end till he could not carry her anymore.
Mistress Gaia knew her slave liked riding horses so when he messed up, she turned him into her human pony and she rode him. She did it for hours and his back was tired and he could not withstand her weight anymore. When he wanted to stop, she whipped his naked body which made him carry her for a few more minutes before he collapsed on the floor out of exhaustion.
Princess Serena loves ponies and she enjoys riding them all the time. However, she moved to the city where she could not have a pony. She lived in an apartment where she could not have a pony and because she missed riding ponies, she got herself a human pony. She got a loser and she turned him into her human pony. She rode him all the time and she did it for fun not as punishment.
Madame Marissa wanted to use her smoke to humiliate this loser. She spat on the ground and she crushed it and rubbed it with her boots. She had this loser lick the dirty soles before they were allowed in. She had a great time humiliating the guy and making him do all the naughty and nasty things that she had in mind. He had no choice but to do them as he feared something way worse.
Mistress Gaia was not amused with how this loser behaved. She decided to turn him into her human pony. She rode him as punishment for his behavior. She made him tired and fatigued like never before and she laughed at him as he begged for mercy. She told him he should have thought of that before he had messed up. But now he had to face the music and pay for the consequences of his actions.
