Back and forth... forwards and backwards... Mistress Vanny uses her slave today as a rocking horse! He may not walk, he must swing his rider forwards and backwards. He squats on all fours and seesaws back and forth, exactly as his mistress wants. While the slave struggles and sweats, Mistress Vanny sits comfortably in the saddle and enjoys torturing and humiliating him. Then she presses her bare, stinky feet into his face. How mean! He has to smell her and kiss her. But the swinging pony has to keep rocking all the time!
Mistress Zora's slave trots after her like an old donkey until she doesn't feel like walking anymore and straddles his back. Fot as long as she wants, the slave will let her ride on his back. Too bad for him that Zora is bored on his back and already has an idea how she can humiliate him further. She stops her pony and dismounts him. She makes him take off her sneakers then pushes his face into them and orders him to inhale deeply. Does that improve his ability to be a good slave pony?! Mistress Zora tries it out and lets him breathe the scent!
For Angelina it's just normal to train her slaves to be a human pony during their slave training. As a young dominatrix she knows exactly how to make submissive slaves follow her orders. Just like this slave should feel honored to be allowed to serve this goddess as a pony. And when her pony can't take it anymore? Then Angelina will just make it move with some kicks!
