He's now her Pony - just like mistress Annabell decided. He should feel honored to be her pony and being allowed to carry his mistress on his back. She uses the crop on his ass frequently to motivate him even more. But mistress Annabell isn't very satisfied with her pony as it isn't able to carry her weight for a long time. Of course Annabell continues to ride him even after he broke down under her!
