Mistress Natalia is very stern rider. First she ride her slave 4-legged sitting in a saddle on his back and kick him with her spurs (sharp texas wheel spurs), after that, she sit on his shoulder and ride her ponyboy 2-legged, kick him with spurs and whip him alot. In a short "break" she let him lick her dirty ridingboots. At the end she ride her slave again on shoulder and make same riding training with much kicking and whipping.
