I shake my head and bellow in fear. She laughs and moves to the side of the stall, watching as I discover my new form. I can't make my head twist back far enough to see past thick, shaggy shoulders, but the hooves and forelegs, combined with the massive snout that extends from my face, tells me what I need to know. I have become a massive black bull!
The realization should frighten me, but I feel intense sexual desire build instead. Not for the girl, though. New scents come from outside this stall, smells that translate into images of many willing, needy cows.
I turn awkwardly, trying to find the exit, only to be stopped by the girl. She grins. "Ah, you have smelled out the herd? If you leave this stall as you are, you will shift back to your normal self long before you can reach them." She took a shining gold ring from a hook on the side of the stall and held it out to me. "Allow me to touch this to your nose. It will allow you to remain a bull long enough to mate with all of the cows you desire."
My thickening mind can only focus on one thing - the females outside. Dimly, I understand what she is saying,a nd I twist my muzzle towards her. There is a sensation of cold, then an impression of weight on my upper lip. If anything, my need to mount is more intense than ever, and when she swings open the gate, I charge for the open pasture outside.
