The days grew into weeks and then months.

The grafts, the implants had all healed very well, with no complications or scaring.

The brainwashing had continued all during the time.

All the while, what was Cindy, was kept unconscious. Until today.

Today was the start of her surfacing to consciousness. Today was the start of a new life, a new being.

No longer was she a girl called Cindy, for branded into the skin just above her pussy was her mark, the logo of the establishment that had transformed her together with her registration number, 10-22-23F.

This ID was a combination of the year of her creation, her natural age, the local establishments sequence number for her and that she was a filly.

But for now, she would be simply referred to as, ‘23’.

Day by day the medications were reduced and changed so as to bring her slowly out from her comatose state to near waking.

It was at the near waking stage that 23 started dreaming. Her dreams were of horses.

At first she was riding a horse, then it changed – she was a horse, running, no, galloping. She was also aware of someone, a man, on her back whipped her, urging her on.

She felt invigorated, alive – and very horny. Galloping faster and faster, the sting of the man’s whip sent waves of pleasure through her., her whole body felt so overwhelmingly full of passion and lust.

She was aware her pussy was wet, she desperately wanted sexual relief, and she whinnied as a horse would in heat.

The mans laugh came to her and she whinnied again – oh how she wanted, needed him to plunge his cock into her, to mate with her, but instead he whipped her and she whinnied in frustration and lust and galloped on.

The dream played over and over endlessly in her mind. Slowly but surely, the dreams took over her mind and her persona. The brainwashing was almost complete.

Little by little, 23 was brought back to a waking state and after almost 3 months she opened her eyes.

10-22-23F was officially born and the human girl called Cindy simply ceased to exist.

She woke feeling groggy and with the same metallic taste in her mouth as she had the last time. A flood of memories came rushing back, the room, the neck collar, the man injecting her.

She tried to sit up, but was stopped by something holding her arms.

She looked sleepily down at her wrists to try and find why she was held down.

There was something wrong with her hands, they looked different ‘What’s happened to my wrists” she murmured, or rather thought she had murmured , except no sound came from her mouth. She cleared her throat and said louder “What’s happening?” – still not a sound. The exertion was too much for her half awake mind and she feel back asleep.

The next day, 23 again woke. The dream she had had was vivid in her memory, the powerful feeling of passion and lust, of galloping, of the beautiful sting of the man’s whip on her bare arse and her desire to have him mate her lingered in her mind.

She reached down to tantalize and stroke her wet pussy. Something was on her hand stopping her fingers from reaching into her hot cunt. She pulled her arm back up and examined her hand.

‘That’s funny” she thought “It’s a horses hoof” she smiled at the dream fragments in her mind. Again she fell asleep.

Little by little, 23 was allowed to remain awake for longer, and little by little her mind adjusted to her new form.

23 awoke, her mind holding onto the dream. Oh how she wanted to be mated. She needed the man’s hot cock in her cunt , to feel his cum exploding deep inside her.

She looked down at her hands. Hooves she corrected herself.

“For some reason I now have hooves” she sleepily thought and smiled to herself as the memory of the wickedly erotic dream came back.

Something else made its presence known. The bit in her mouth.

Her tongue had found it and now she was aware of its presence. “ What the hell is this” she thought.

She explored it with her tongue and hooves. “It’s a mouth bit,” she smiled again,

“Oh god, I need mating” . “ Did I just say mating? “ she asked herself “ Funny” she thought “Mating is such a beautiful word and so much better than ‘being fucked’ ”

She looked down at where her feet should be but found she had very limited ability to lower her head, so she raised her leg so she could examine it.

“Hooves for feet, I am a horse then” and smiled again.

Something else prised its way into her mind.

There was something wrong with her lower back. She had found dozing on her back uncomfortable and now she reached down with her hoof and examined it.

It didn’t take long for her to realize what it was.

“A pony tail !” she beamed “ A lovely, lovely pony tail” again she drifted off to her erotic dream and smiled in her sleep.

One day a man who she had not met came to her bed just as she woke from her dream.

“Hello 23, how are you feeling” he asked.

23 looked at him and her heart raced “Is he the man in my dreams?” she wondered.

The man reached down and touched her cheek. “Do you want to know more about yourself 23?” he gently asked.

23 nodded and blushed. Her pussy was still wet from the dream and she was in a state of high sexual arousal. Her nipples betrayed her feelings, something not missed by the man at her bedside.

He smiled at her, seeing her obvious discomfort and embarrassment.

“Don’t worry, that is how a pony like yourself is meant to be”

“You yearn to be ridden, to be controlled, and whipped” he added.

23 stared at him, feeling even more embarrassed that he knew her mind.

“Your name is 23” the continued, “because you are the 23rd ponygirl to have come from this establishment.”

“You have hoofs for feet and hands; you wear a collar, bridle and bit to show that you are broken in and as a means to further train you in being a pony. You also have ears and tail of a pony “

With that, 23 moved her hoof to her head and felt the new attachments.

“The way you feel is normal and natural and is the way a ponygirl.

“ The sexual excitement and arousal of being controlled and commanded, of being owned as an object is how you should feel, revel in it and enjoy it “

“You have also been enhanced physically to make you more appealing sexually”

“Would you like to get off the bed and see what a beautiful creature you really are now?” he asked and held out his hand to her.

23 held out her hoof and he gently helped her to stand. She was unsteady and wobbly. The hoof’s that were now her feet felt strange and balancing was difficult.

“Take small dainty steps, it also helps to bring your knees up much higher than you are used to” he said.

23 took a few steps with the aid of the man’s support.

She followed his suggestion and found that walking and balancing was much easier.

He helped her to walk in front of a large wall mirror where she could take in the full sight of herself for the first time.
