Equestrienne Mistress Serena takes her loyal steed out through the fields for some much needed exercise. He is worked hard under the sun, and encouraged to perform properly - Goddess Serena demands excellence and wants an award winning stallion, not a lame mongrel!

Once the human pony is tired out from his merciless hike, his Mistress commands him to bend himself over the trap's bench and prepare his bottom for a good, old-fashioned punishment with her riding crop! He has done a good job, but he must remember what will happen to him if he ever fails to impress her.
