Wildfire glistened in the mid-day sun as the canted through her paces. She was taking to the surgically implanted hooves and her balance was adjusting. The "Thyr-steri" treatments where making her taller, stronger, faster, giving her unheard of endurance. Her rider felt light on her back.

She shook her mane, trying to remind herself it was only a bad hair cut. She clenched the bit in her teeth, trying to ease the relentless pain in her jaw from the sawing reins. Mistress Safia was an unyielding woman, but Wildfire was learning quickly that if she obeyed, Mistress Safia could be quite pleasant.

Wildfire didn't want to obey.

Safia was breaking down her will, slowly, surely. Soon Wildfire would forget her own name.

Alice had been a mousy, plain woman who hungered for a romp on the wild side. She had met Safia in a BDSM club. Alice was rude, brash and uncontrollable.

"You're a wild little filly, aren't you?" Safia smiled with her eyes as she spoke.

Alice was three sheets to the wind as her blurry eyes fell on the mistress. "Ya thinks ya's hot shit, don't cha'?" She slurred. "I bet ya can't tame me!"

Safia smiled. "I already have."

Alice looked at her curiously, then looked at her glass as the world spun away from her and the floor rose up and smacked her in the face. One of Safia's special teas had done the trick. Safia would have simply sent the girl to one of the rooms upstairs to sleep it off, but the girl had had to challenge her. She signaled her hand maiden. "Take her to the car. I believe I have found my new filly." she said, as Alice slipped into darkness.

Whipped to break resistance, then the treatments to make her grow, Alice, now Wildfire marveled that even her breasts were swelling. Perfect orbs, they were only a purchase for Safia to punish. She screamed into her gag as the surgical screws permanently attached hooves to her feet and a wispy tail to her spine. Oddly enough, the most humiliating thing was the hair cut. The stupid horse hair cut. When Wildfire looked her reflection in the watering trough, she didn't know who it was looking back at her.

"I have something special for you today, Wildfire." Safia announced as she reined her towards the barn. "Today we apply the final finishes that will make you my ponygirl forever."

Wildfire felt her knees weaken, but there was no use in resisting. She had lost all will to fight the day Safia branded her. Amongst the screams and acrid smoke, Safia threatened, no, promised: "That was a taste, my sweet. Misbehave again and I'll brand your other cheek." Safia then put cool salve to dim the pain. But it lingered as a reminder and Wildfire never misbehaved again.

Her reins were removed and replaced with her ball gag. Wildfire was always gagged except for eating and sweet kisses from her mistress. Then her corset, that tight, wind-stealing corset was removed, and replaced with a steel belt that constricted her waist even more. Wildfire cringed from the sparks of the welding gun as it was permanently sealed up.

Next, heavy brass collars were squeezed over her breasts until they hung like little blobs of dough on her stomach. They felt very odd hanging there, brushing against the cold steel of her belt. Then, because everything has to be extreme with Safia, titanium shafts were pierced through her breasts to permanently secure the brass collars in place.

A new collar and harness were bolted on, connecting to the steel belt. This form-fitting brace would allow her spine to carry a rider easily over many miles. Then Wildfire's arms were positioned behind the back prayer style and riveted in place, her hands sealed in mittens. "A proper ponygirl has no need for arms." Safia explained. "They will be uncomfortable for a while, excruciating in fact. But as they atrophy, the pain will subside, along with your memory of the girl you used to be."

An aluminium saddle was then bolted on. The mittens were positioned to be the horn of the saddle and at the right spot to entertain Mistress Safia as she rides. Stirrups were attached and Wildfire was ready.

Safia turned to the stable girl. "Feed and water her. I can't wait to take her out for a ride."

With difficulty, Wildfire bent enough to drink at her trough and saw the reflection in the water. She looked nothing like that girl she used to be. "What was that girl's name again?" Wildfire wondered to herself, as for the life of her, she couldn't remember that girl's name.
