Princess Violetta and mistress Joschi found this guy repulsive but he thought he was God's gift to them. They hated his guts and wanted to tame his balls. So they invited him to their house where they turned him into a human pony and rode him naked all over the house. They did it while naked too so he was double dominated as he was turned on but could not get some and was physically dominated by having to carry them around.
Lady Lucy was feeling freaky today and being that she was dominant over her boyfriend, she wanted to do something naughty to him. So she teased him and got him in the mood and then got him to agree to be her human pony. The mistress rode him all over the house and she had fun even though she could see he was struggling to carry her after some time.
