Railing Horse Or Lame Horse

Mistress Anna has her pony slave absolutely under control. Finished bridled he is ready for his railing mistress. Mistress Anna sits on his back and rails him. Today she will judge his spectacle as a pony and determine whether he can be used as a railing pony or is just a lame stupid pony. With the crop she pushes him forward and rides faster and faster lap by lap. Only through this training she can find out if the pony slave is good enough for the mistress!
