I gave an equine snort of surprise as Karyn's wish took effect. Her weight shifted on my back as a saddle appeared underneath her, the cinch tightening around my new barrel-like belly. A sharp mettalic taste filled my mouth as a bit forced its way between my jaws. I felt straps forming around my long muzzle that connected themselves to the bit. I shook my head at the strange sensations and felt reins slapping against my neck.
Karyn gave a delighted laugh and tugged a bit on the reins. I huffed a little as the bit pulled on the flesh in my mouth and said, "Now I understand why horses obey their riders." My voice was not much affected by the bit, since it originated somewhere back in my neck.
Karyn patted my neck and said, "Maybe if you're a good horsey I'll do cross-reining instead of a bit, but for now..." I was still wondering what cross-reining might be when I felt two dull pokes at my flanks and heard Karyn yell "Giddyup!"
I was startled enough that my equine side took over. The sudden noise and pokes jolted me into motion. My hooves clattered on the sidewalk as I broke into a fast run. It was exhilarating -- the feelings from my body as its altered muscles bunched and released, the wind in my mane and tail, even the tight grip of Karyn's knees on my sides and the shifting of her weight as she moved with me.
How long we ran I'm not sure. I responded to tuggings on the reins to turn this way and that. I was vaguely aware of traffic on the road and people moving out of our way on the sidewalk. All of it was lost in the sheer pleasure of motion.
When Karyn finally pulled on the reins and said "Whoah, big fella. Whoah." I realized that she had ridden me all the way to....
