Mistress Sonny and mistress Bonny are gorgeous girls. They like weird fetishes and today they got this guy who was so desperate for a threesome that he did all the crazy things they asked him to do. He was turned into a human pony and the mistresses rode him all over the house. They rode him together and nearly broke his back as they did so. But his endurance paid off in the end as they were impressed with his stamina and his high pain threshold.
