Mistress Dula and her friend love to dominate guys for fun because they have a fetish for pony play. Today they were doing it to a loser and they spent time riding him while he was naked. They wanted him to be naked so that it would be easy to humiliate or punish him in the event he did not cooperate with them. Luckily for him, he cooperated so he was not whipped.
Mistress Dula and her friend had human ponies and today as they were hanging out with them at mistress Dula's house, she suggested that they race them to find out which among them was faster. They also sat on them to find out which one was more enduring. They then scored them for fun after they had had a bet. It as humiliating and painful for the human ponies but the mistresses did not care.
