Bronwyn bunched the panties, put them on the top of her other clothes and turned to face John. He guessed that she was 5'6" tall and no more than 9 stone. She was slim, but not wafer thin, had strong thighs and square shoulders - attributes he and the club looked for in a wild Pony-girl. Her breasts were a decent full hand size while her butt cheeks were gloriously pert and well formed.

The pretty PA gave him a bold smile and belatedly replied to his statement. "Actually, John, I'm already proud of my body."

"That's good to hear, Bronwyn. Your nerve is going to be put to the test, but each session in the wild will make you a much stronger woman."

"Henrietta thinks that I should see what it's like to lose control for a short period. I have led a very comfortable life."

He understood Henrietta's desire to test her girlfriend's metal. She stood to attention, naked as the day she was born. He could see that she was extremely nervous.

He stood beside a low bench, where he had placed some of her tack. "Firstly, Bron, you will call me 'Master' whenever you are in my charge and have the ability to speak." He pointed to a tawse and short snake whip lying on the bench. "Misspeaking will get you a stroke or two. Do you understand?"

"I do, Master."

He was impressed by her quick response. "While you are in the wild, you will be treated exactly the same as the wild Ponies. Is that understood?"

"Yes, Master."

"You will be an animal and no longer have human rights."

"I know, Master."

"Bron, turn around and bend forward... That's it, put your hands on your knees and part your feet."

He ran his fingers along the tattoo 'BRON', that had been inked in fancy italics just below her coccyx. "Was this Henri's idea?"

"Yes, she thought it would look cool..."

He eyed up her baby-smooth, thrusting labia, parted by a regulation two and a half inch long clitoral clamp, a crude chastity device. "How long have you been wearing the shield?" He stroked the surface of the shiny protective grip, causing her to flinch briefly.

"About a week, Master. After the trouble with Ralph. Henri takes it off at night... it's her way of telling me that my sex belongs to her."

The grip was spring loaded and locked in place by turning a screw with an Alan key. "All female club members wear them for three reasons, Bron. It's more hygienic in the wild and stops you from pleasuring yourself by rubbing your cunt where you shouldn't. It also makes it easier for the Pony-boys to locate your quim. The wild Pony-girls have had their labia laced with wire thread for exactly the same reasons."

He ran his hands over her firm buttocks and squeezed the musculature. "Your gluteus maximus are firm, do you run, or go to the gym?" He could feel her body tense as his fingers kneaded her firm flesh.

"Yes, Master, I go to the gym three times a week."

There were several faint stripes running both ways, but the blows had avoided her cunt. He traced the lines with his finger. "A woman delivered these, Bron. Am I right?"

"Yes Master, you are right."

Discovering that he had a timid lesbian on his hands confused him somewhat, but if she was the vet's girl, he was sure that Henri wanted her well trained; and that meant plenty of punishments.

He hunkered down and slowly moved his hands down the lower slopes of her buttocks, ensuring his thumbs rubbed along her labia lips. She quivered while he rubbed her sex and then relaxed when he moved down to the back of her thighs.

"You're in good shape, Bron. Stand and turn around." He waited for her to face him and then handed her a pair of black woollen leg warmers. "Put these on." He waited for her to draw them up her legs and then showed her a brown leather hood. "I'm going to fit this now. It's probably the most difficult thing to get used to, but once it's in place, the rest of your tack is fairly straightforward."

It was a shame to cover her beautiful features, John thought. She stood still while he offered the opened hood against her face. "Turn around, Bron." He pulled the sides, until he could start to slowly pull the zip down from the top. He took great care to gather her hair and tuck it in, as he pulled the fastener down. It travelled lower and lower, until he arrived at the bottom of the three-inch neck lining.

"The next item is your collar. Probably the most important item of your kit."

With Bron facing away, he placed the hard, plastic strip around her neck and pushed one end into the small box on the other end, at the back. After ensuring the electrodes were in contact with the sides of her neck through the holes in the hood, he pulled the tab through, tightened it, then locked it in place with an Alan key. Until it was open, the collar could control the girl and make it impossible to remove the hood without removing the collar first.

He turned her around and smoothed out the supple leather around her eyes, nose and mouth. "The next item is your bridle and once it's fitted, you won't be able to speak. Have you any questions?"

Her anxious brown eyes betrayed her thoughts, but she shook her head in the negative. The eye and mouth holes in the hood were a generous size, but it was the feeling of being imprisoned that helped to keep the Ponies under control.

The bridle straps fastened around her forehead, under her chin and over the top of her head. They had to be tight, because several 'D' rings provided a number of attachment points. It was to two of these, at the sides of her mouth, that he attached the skeleton bit.

The main part of the bit was a flat elongated plastic tab that pushed into her mouth and sat on her tongue. It had two 'U' shape connections at the front that pulled the sides of her mouth back and clipped onto the 'D' rings.

When the reins were also connected to the 'D' rings, pulling on them drew that side of the mouth further back. Pulling on both, lifted the front and forced the back of the tab onto the filly's tongue. The bit was thin and extremely tough, so it didn't matter if she tried to bite down on it.

"Comfortable?" he enquired. She stared back at him. "When I ask a question, I expect an answer. Grunt once for yes and twice for no."

"Huff, huff..."

"That's better. I won't warn you again, Bron, I will just punish you. Understand?"
