Mistress Roxy now mounts her new pony in all-fours position and makes him carry her around no matter how exhausted he is. She makes him do donkey lifts and then more all fours riding. The pony is new and not used to the hard work of being a pony so you can tell he is struggling under Roxy's weight. She weighs 160 lbs. (73 Kg) but she doesn't care if he is tired. She rides him even harder and makes him buck for her pleasure.
