Mistress Bambina likes to do naughty things to other people. That is what she did to this new loser. She was with her friend at the time and the two of them joined forces and they rode her like a human pony. The mistresses nearly broke her back as they did so and they had fun at her expense. She had to endure the pain or else they promised to punish him using a worse method.
This mistress learned that not punishing a slave was setting him up to disappoint her so she humiliated him with advice and instructions from her friend. The two mistresses turned the slave into a human pony. He was humiliated and made to endure a lot of pain. He tried to plead for mercy but none of the mistresses paid attention to him. He was then trampled before they were done with him.
Mistress Gaia likes to torture. She is a sadistic mistress who enjoys being a source of pain and misery to others. She enjoyed what she did to this loser and only let him go when she had made him carry her all over on his back. He tried to beg her for mercy but she did not listen to him. She just did her own things and did not bother to hear what he had to say.
This mistress and her friend had a bet. Whoever won it would ride the other like a pony. This mistress won and her friend had no choice but to carry her. She carried her like a human pony and the mistress rode her all over. She was tired but she could not stop as she had to fulfill the terms and conditions of the bet. When she finally stopped carrying her, she felt like dying.
