Miss Tina looked at the time stamp on the lid of the crate and realized the women had been in their positions for almost 48 hours now. There was a sealed envelope inside the crate too. Miss Tina picked it up, opened it and began to read:

"Dear Tina!

These are Jeanine and Friederike, or shortly Jean and Friede, two women of age 25 (only 53 days apart in age. Jean is the older one). Jean is 6 feet tall and weighs 160 lbs, her measurements are 34b-25-35. Friede is 5'6''and weighs 125 lbs, her measurements are 36d-26-36. They have been a lesbian couple for 5 years already and recently discovered the BDSM lifestyle, only to find out they are both very submissive. The two are very promising slave material, and I want to turn them into ponygirls.

I want some body modifications done on them, and since I know of your skills in that area I send them to you. I added a list of what I want done to them; take whatever time you need for these modifications.

Looking forward to the results of your excellent work

Your friend Cindy!"

Tina took a look at the list and couldn't help but smile. This was a challenge, and she loved challenges.

Tina bowed down and carefully untied the women. First she loosened the knots that connected their feet to their hands, next were the ties that held their arms in place. Slowly she put their arms into a more comfortable position; she knew that after two days in this position their elbow-joints probably hurt a lot. Next were the feet; they too were released and pulled carefully over their heads back in front of their bodies again.

Tina turned to their hoods then and deflated them first; then she opened the zippers and pulled them over their heads. She realized the hoods had inflatable butterfly gags inside, through which the breathing tubes had run. The girls jaws surely had to hurt.

They seemed to be too weak to move or make any sounds; the only thing they did was carefully move their jaws around. Their long hair had been stuck under the hoods; it was quite sweaty now and and clung to their heads in a matted way. Jean's hair (Tina could tell them apart by the descriptions of them in the letter) was blond with just a trace of red, Friede's hair was totally black.

Tina took a brush and carefully combed out their hair. Both their hair was very long and reached down to their asses. Jean's was straight, Friede's was quite curly. The girls looked at her with some trepidation. Tina smiled down at them reassuringly, then she removed the neck corsets from them.

"Now, don't be afraid. I am Miss Tina for you. I apologize for your inconvenient trip here, but your Mistress wants a few things done to you, and this seemed to be the easiest way, since we are so very far apart. Do you two know of the plans Mistress has for you?"

The girls carefully shook their heads in unison; the first movement of their necks within the last two days.

"Well, she wants you to become ponygirls. Do you know what a ponygirl is?"

The girls looked at each other, then back at Miss Tina, and slowly nodded.

"You don't seem to be enthusiastic," Tina remarked. "But surely you trust your owner and believe she knows best what is good for you, don't you?"

The girls nodded again.

"And you trust me too, since your owner obviously trusts me?"

Nods again.

"Fine. The first thing I have to tell you is that from now on you will no longer speak. The only utterings allowed to you are neighs, whinnies and snorts. Is that understood?"

The girls looked at each other again, then they both whinnied.

Tina smiled.

"The next thing I have to tell you is that you have new names from now on. You - she pointed at Jean - "will be 'Thunder' from now on, and you" - she pointed at Friede - "will be 'Lightning'. What are your names?"

"Thunder" replied Thunder.

"Lightning" Lightning added.

Tina sighed, then she got up, took a riding crop and gave both five smacks on their breasts.

"What did I tell you your only utterings had to be?" she asked them while she hit them.

The girls quickly whinnied.

"There, that's much better. It will become second nature for you in time. Now, the first thing I'll do is get you out of all that you wear and remove those catheters from your urethras and asses."

Tina carefully loosened the threads of their corsets and pulled them off; they left interesting patterns on their bodies. Then she got them out of their boots and gloves too. She deflated the dildos in their pussies and asses and removed them; then the balls that held the catheters in place were deflated too and carefully pulled out. The girls cautiously tried to move their feet and fingers, without much success; they had become quite stiff during these two days.

"Now, I have to tell you that for becoming ponygirls your bodies will have to undergo some transformations. The first of these transformations will be that I will remove all of your hair from head to toe, and I mean all. Yes, this means head too, including eyebrows and eyelashes. Even the visible hair in front of your nostrils will have to go. There will not be a single hair on you, not even the finest fluff or the odd stray hair. One could search your bodies with magnifying glasses and would not find any; the only hair you will keep will be deep inside your nostrils were no-one sees them, because they are needed for filtering the air. And this hair removal will be forever; you will never have any hair again."

This seemed to terrify the girls, and tears ran out of their eyes.

"Now now, don't weep. You will get used to it and even love it in time. Other girls underwent the same process before you, and they loved it very much when the initial shock was over. Well, let's not waste time. Can you get up, or do you still feel to stiff?"

The girls tried to get up, but their legs failed to support them, so Tina lifted them and placed each of them on a chair.

She walked into the bathroom and returned with a set of clippers, shaving foam, a safety razor, a pair of automatic tweezers, a fine brush and a lidded can. She plugged the clippers in and removed the attachment, then she told them to put their heads together and started running the clippers over their heads. The girls started weeping again while strand after strand fell to the floor, building up a pile of blonde and dark hair at their feet. She ran the clippers over their eyebrows too. Then she put an eighth of an inch attachment on the clippers, told them to spread their legs and carefully shortened their bushes, making sure not to hurt the clits or labia. She then lathered them up from head to toe. Even the fingers and faces were covered with shaving foam.

Then she began the shaving. She slowly ran the safety razor over their heads first, scraping away the stubble. She then worked her way down their bodies. Meticulously the hair around their pussies was removed. She then made them get up and bend over the chairs. She spread their asses wide and freed the insides of them from hair too. When the asses were done she told them to get back on the chairs and finally did the legs and toes.

When all the foam was scraped off their bodies she took the automatic tweezers and started plucking out their eyelashes and the hair in their nostrils. Surprisingly plucking the eyelashes did not hurt at all, they hardly felt it. Plucking the nostril hair hurt all the more though and even caused some tears in their eyes.

After all the hair was removed Tina told them to close their eyes, put on a pair of rubber gloves, opened the can and smeared a foul smelling green paste all over their bodies, even on their eyelids. She put some of the paste on a fine brush and did the inside of their nostrils too. Even the pussies and the inside of their asses were treated, as well as their ears including eardrums. The paste burned on their skins.

"This is a permanent hair remover," Tina told them. "It kills the hair roots. You'll never have any hair again now. Perfectly smooth for the rest of your lives." She waited 15 minutes for the paste to take effect, then she led them into the bathroom, put them into the shower and rinsed them off.

Tina dried them, then she led them in front of a big mirror and told them: "Now have a look at yourselves". When they saw their hairless reflections, they started weeping again, but Tina kissed them on their heads and told them how good they looked now, and that they should be proud of themselves.

"Now for the piercings. You don't have any at all yet, not even your ears are pierced. Well, this will change, and quite drastically too."

She told them to sit down on a chair again, took the piercing forceps and started her work on them. First their ears were pierced at the bottom, and golden hoops with six inches diameter were inserted into them. Next she pierced the septums of their noses, the rings she inserted there were two inches in diameter. Next the tips of their tongues were pierced horizontally and a small golden ring inserted, then their throats, nipples, navels and clits. All of these piercings were given golden rings too. The outer labia received three rings left and right. One ring was placed at the bottom of each of their pussies, a so-called "fourchette". Finally the anal sphincters were pierced too. When Tina was finished with them each had received seventeen piercings. The piercings caused them a lot of pain, especially the nipple and clit piercings, but the girls didn't dare to shout and only whinnied a bit.

Tina told them what good ponies they were and petted their heads. They felt strangely elevated and were even proud of themselves.

"The next step requires some surgery. Follow me."

She led them into the operating room and told them to lie down on the two operation tables in there. She fastened straps around their necks, their bellies, ankles and wrists. She then pressed a button, and two other women appeared, both clad in green surgeon's aprons, with green pieces of cloth above their mouths. Tina disinfected her hands and put on the same, then she told them:

"These are Dr. Lynnot and Dr. Spencer. They are cosmetic surgeons and will alter your bodies now. You will fall into sleep, and when you awake you will be changed."

She put a 14-gauge needle in both their arms and left them in there. Then Dr. Spencer first approached Thunder and injected something into her veins. Lightning saw her close her eyes, before Dr. Spencer came to her table, injected something into her veins too, and she fell asleep.
