Mistress Zora enjoys making life difficult for her slave pony. First she whips him mercilessly and then sits on his back to send him walking on all fours. He has to carry her around as she wants him to and is not allowed to show any signs of fatigue. After all, Mistress Zora uses this to humiliate him even further, to beat him and to ride him for much longer. Obedient slave ponies are not allowed to get tired - and he learns that now!
