This is the very last chance for the slave to prove himself to Princess Serena and show that he has what it takes. The princess turns him into a slave pony, sits on his back and rides him as she pleases. She sends him forwards, sideways and backwards. The main thing is that he obeys her and does his best! But even as a human pony he is a loser and deserves notjing but a beating. Nevertheless, Princess Serena doesn't let go of him and gets her fun at his expense!
