Frank’s brain was in overdrive using every vestige of his remaining humanity he had left to force himself to remain calm. The undercover couple that had infiltrated the club had turned to start stepping toward him, as the man and the woman got closer to his stall. They were close enough to touch him over the open stall gate and he saw in their eyes that they had recognized and remembered who he was and he nodded his head so slightly yes as if to signal he remembered them.

Frank remained very calm as the woman reached to stroke his shoulders, face and ran a hand under his chin. Then she traced a line down his now smooth hairless chest, yes his body hair had been removed, toyed with his limp hanging chastity ringed penis.

"Must be uncomfortable this thing," she said referring to the chastity ring device around his dick, perfectly in undercover character. The man with her also in character nodded, saying. Yes, that ring device detects the pressure of the erection, when the animal’s cock expands in that erection and becomes over aroused, becomes too firmly erect without permission to climax and punishes the animal. Given the sex hormones plumped into him, and the psychosexual conditioning it is not like the stud can control it, but it will get punished anyway. One of the staff the dark haired, dark eyed groom the regular who maintained him, opened his stall gate and clipped a long leash to his collar. She checked that his restraints were all in order and led him out of the stall with a slight pull. His hobbles had not been removed, which meant that there was going to be no running. The staffer disabled offhandedly the punishment device on his chastity ring. Frank fell into his ponyboy character and walked after the groom with short hi prancing steps, ignoring the guest couple and their gazes. He felt more than saw that they were following along as the staffer lead him towards a two-story building where he had never been or in before.

Frank heard some murmured remarks from behind him, but he could not pay attention because he was concentrated on the all-important business of walking properly, with the right amount of stomping, and in the ordained position of one step behind, one step to the right of the person who was leading him. The four entered the building through an open double door and stopped in front of the Matron Director his hooves making that unique sound of pony hooves on a solid wooden floor. The Matron Director arms folded across her chest had an odd look on her face, she appeared to be waiting for them in the middle of that room in which Frank saw off to the side in that room a low bench and chair laid out with clothing. There also was a small refrigerator in the corner would hold soft drinks and water, chilled to a perfect point for the guests.

Frank felt as if there were two people in his head. He could swear his brain was mentally split in two as it was physically was in two parts: the human male right hemisphere hoping anxiously to be freed, with its desired dream of having his ponies with him. The other left hemisphere a stallion, waiting anxiously for orders, to be rewarded and being attentive to form, as long as he stood perfectly still at attention these two hemispheres of his brain, of himself were both satisfied. While both hemispheres asked of his spilt brain asked what did he need to do to help the outside miracle along?

The Matron Director of Livestock smiling was dressed as a turn of the century English squire in tweeds and leather boots. She welcomed the two esteemed guests from outside local security and said that, if everybody was ready, it was decision time, as the double doors they came in by where locked closed from the inside.

Frank by experience knew the Matron Director was about to deliver a lecture, observed behind the Matron in the room a pair of large sliding doors which she slid open to reveal tied to posts and frames in the next room was on the right the human ponygirl Springtime, on the left the now pony girl April and between with all four of her legs bound to her special frame the delicate undersized pale blue-gray coated Arabian Mare Springtime. Frank was in his condition amused to learn that two of the fillies were named Springtime. He fondly recalled the short time as his mount the gentle delicate under sized Arabian filly, now his mated mare which he rode in on. The other was the ponygirl he had fucked in the ass and unsuccessfully was unable to communicate when unplugging her that same day and last the shared plugging experience with April who he saw when she was still a human girl, just hoping for a better new life.

It was clear they were in that bound position to allow the deepest penetrations of vagina and anus while being quite comfortable for both sexual partners.

Frank with a start his penis had been hard the moment he smelled and saw all three of them. The Matron Director waives to the couple who remove piece by piece his arm glove, his hand gloves, his body harness his pony hoof boots, the chastity cock ring, the collar around his neck every item of tack restraining tack, except for the plug in his mouth and throat Frank still is automatically in that comfortable rhythmic spasm of sucking and swallowing. Stripped nude without his tack Frank his forelimbs hanging limp sore at his sides waiting for the circulation to fully return, waiting to respond to the nerve impulses his brain is transmitting for them to flex and move again.

So far nothing happened, and his hands painful lower themselves to remain loose free at his sides to move, he cautiously started by flexing his fingers. The hobble chain of one meter that linked his thighs together was removed which again allowed full movement of his legs, Frank-Senior was physically free.

The Matron Director cleared her throat and then started the expected lecture: "Stallion Senior who was once a man named Frank, you have completed the Club requirements of an uninvited guest. I must say you turned out with your hidden potential to be a rare Stallion among ponyboys, and you I hope will choose to consider this a strange interlude, perhaps akin to a military boot camp or an internship in a rather peculiar Club. Last at most a hazing to become a permanent Club fixture, we know that you entered this place voluntarily of you own free will, uninvited seeking something only you truly know. However like everyone who finds their way here it is not what they expected as you learned firsthand yourself that first day with April and this time were also a form of pleasure and profit for us here at Silver Saddle Hills Club.”

But as you have been told and now shown very clearly ponyboys and ponygirls at this Club are here as livestock voluntarily. It may not look so, because of the bondage, the punishments and the harsh training technique, but this is the truth. Everybody in these stables the pony girls, the pony boys, all the staff and these two outside security enforcement agents witnessing your testing the decision we have all made, just like today you are going to take yours.

As you have noticed, we have freed your arms and legs, and you are free to make a choice. Actually, you are not free: you will have to decide entirely on your own.

The choice during this test is you can return to the outside world as you are, you can turn right now, walk to that bench, dress in those clothes sized for your developed physically figure. Remove the plug and unlock the door to leave. You will be permitted one last long look at the club. After which there two agents will escort you to the outside world. You will again be the man Frank, except for the bonus of your hanging enhancement. You will return to the outside world to be free under a suitable cover-up story provided by these agents. It will be as if nothing ever happened cornering anyone on the outside. Plus you will never be permitted to return to be inside this club or anywhere near this club again. It will be as if anything had never happened, at least outwardly, of course that potential now revealed to you will always be with you. It will influence your sexual tastes bent for pony kink sex you, I am now sure have acquired will be entirely your own affair to conduct. You might find that your new required sexual tastes and equipment, especially in sex will make it difficult to resume your previous lifestyle, but I am sure that you will find your way into what is called, I believe, the Pony play culture. In the unlikely effort to replace these three fine individual ponies. The Matron Director had the gall to actually to sniff at the words "Pony play culture".

Or Senior my new ponyboy, as a stallion you can walk right on behind me to screw all three ponies I am sure you now know your mated for life mare and the two virgin fillies you desire to do more than folic with, as many times as you like for the rest of the day as a reward. You and those three ponies are going to earn the club a huge profit at your weekly three way livestock harem sex show. As they will be sexually corrupted to engage in female pony lesbian sex.

Just look at them the lovely Springtime ponygirl, all tied up, virgin wet and wanting for you to make her a mare as a stallion which will complete her psychosexual conversion into livestock. Look at her I think she is trying to wiggle her hips despite the bondage. Next look at your matched cock to vagina true mated for life delicate mare, the only one of the three presently able to take you’re erected hanging equipment fully. Springtime the delicate Arabian horse, undersized as she is lucky to have you for a stallion, a true stallion would rip her apart, likely damaging if not killing her, see she is wiggling her hindquarters and tail for her stallion. Fuck both of them plus there is the one you did meet when she was still only a human girl, in a way you are responsible for assisting that day in helping granting her desired to vanish. Further you assisted pony April to look forward to the new existence I gave her, look she also is presenting her sex for you to take and help complete her as simply livestock, to abandon the remains of her humanity. This one time your hands will be free to touch fondle them the way you desire and show them what animal lust they arouse in you Stallion Senior.

The Matron Director of livestock training her full title was not going to make it fair or easy as she reached out with both her hands to stoke the fully erected forty-one centimeter shaft engorged with so much of his blood he began to feel light headed which further sexually aroused the stallion Senior. The Matron says I think you had a part in making all of three of those ponies the way they are, Senior are you going to take responsibility as a stallion?

After you have had your fun, you will be restrained again, taken to your stall and given a full twenty-four hour cycle of rest. And then you will stay here, as a ponyboy, a stallion. Occasionally you will be checked on to make sure you like everyone else are doing OK and to play with you. There may be more opportunities like this one at the moment, or not: I am not promising anything, and I advise you to treat this as a once a lifetime chance, to create a harem. You have not been unplugged because there is nothing for you to say at this point, or that we would even care to hear. Leave and do what you want with yourself outside or stay and be the clubs livestock. Live as we tell you as the animal you are now. You can remove the plug yourself while dressing on the changing bench or you can keep your plug on and fuck these ponies.

The Matron with both hands has been slowing guiding Senior the stallion by the cock closer slow step by step to the hind quarters of his mated show mare. The Matron continues her lecture, just to be clear the moment your cock my stallion senior touches the mares pussy lips or the moment you unlock and step out that outside door you will have permanently decided. Soon now you will have to make your choice as Frank is now only a step away in those stoking hands from plunging the head of his mushroom glands as Senior into the awaiting vagina muscle hug Springtime the mare will deliver.

The matron played her trump card firmly now jerking that stallion’s cock, that trump play the Matron Director was to have the opposite effect on Frank. Frank by the thinnest of margins was about to lose his humanity entirely; when he looked realizing he was seeing his future as a stallion and livestock.

What Frank saw as he turned his head to look instructed by the matron as she aroused him, the Director looked amused and actually winked at him, her hands tugging him toward the ponies his cock so desired. The woman agent was looking at him open mouthed drooling with that all too familiar facial spasm. The male agent behind her then smoothly inserting a plug in that mouth as she began a cycle of rhythmic sucking and swallow spasms and her eyes vacant half closed he strapped that plug about her head. The agent explained yes we were uninvited undercover private investigators following up on our own time what is done here. While he stripped her of the sweat suit to fully outfit her in tack, arms bound pinned behind her back,. with his hands groping the ringed nipples the at her labial hood. Soon he had his sweat pants down round his ankles revealing he was hung like a pony boy, soon his erect cock half buried her ass. Continued to explain we were subject to what you just experienced, my partner as you can see is no longer human. I still retained some of my humanity but could not leave the ponygirl behind who I knew was the only one that could satisfy my stallion hung cock. So the Director and I came to a win-win mutual agreement, I got to keep my pony to use her outside in private, with a regular vacation stay mixed in here as a matched pair. We became the outside security you met us shortly after we joined the local police force, we were investigating you and came across your insurance in the event you vanished. Today we were invited to witness your choice test. Now if you excuse me my pony requires a open fucking in front of someone that she has not had done to her since our last visit.

Frank was for once in his life thinking with his higher head and not the lower head, for if he had been a young man there was no doubt where his cock would be plumbing. The Director Matron would have done better without her trump card. Just if he had been offered the choice alone to create a harem, be their stallion he would be into those three ponies at this instant and the future to be hanged. The Director did not realize what her words Frank did understand and all the lectures on theory of changing humans into animals with sex he did get, very precious orgasms with these ponies that would leave him frustrated, going insane wanting for more.

Frank took one longer look into the three pairs of eyes; a shudder racked him for in those three pair of ponies’ eyes he believed seeing the same bittersweet emotion and message, “PLEASE TAKE ME- MAKE ME YOURS!”

Again Frank was tempted to think with his lower head. In a flash he remembered what happened here to him. Could this be real? If this was real why wasn't he already getting dressed changing into normal, human clothes and getting ready to go back to live in the outside free world as he dreamed of doing again?

It became clear what he had to do, for to remain in the club would only result in an endless succession of days consisting of training, punished erections, sodomy and out of his control rare climaxes. From where he stood now able to flex his arms buying a little time, Frank could see the glistening fluids around their sex. Why the hell wasn't he running out of this place? His dick was bobbing in the air, harder and thicker than it had ever been, in the hands of the Control freak Director engorged with a full pint of blood, which was making him light headed. Frank imagined walking to the bench dressing and then got the fuck out of the ranch and rejoined his normal life, to regretting always leaving those three behind. In his lower head he could see that his body took was about to take the last step, the Matron withdrew her hands expecting yes I got him. Before he knew that his hands were reaching out to pat first the Arabian mare’s hind quarters to his front. Then one hand to either side patted the soft firm ass cheeks of the human in name only ponies to his right and left. Only a couple of centimeters of air still separated his mushroom sized cockhead from the wet ready vagina opening of his mated Arabian mare.

Frank turned a way to hear the saddest tiny sounds he was to remember for the rest of his life, first turn step away from the brink. His first action was to remove his plug, to step over without a word to the male agent and offer it to those male agent’s lips. The male agent cock still half buried in the ass of his female pony partner, was nodding her head yes-yes. The male agent accepted the plug, and then the arm glove as Frank stripped the agent of his sweats to become bare as his female pony mate. She assumed a position on all fours on the floor as the now Frank outfitted in tack male agent revered to being a pony boy mounted her from behind.

Frank next stepped over to sit down on the bench to ease the dizzy light headed feeling he had and looked to reach for the clothes to start dressing.

The Matron Director shunned that this rare stallion still had a vestige of humanity left still had not given up thinking time to take extreme measures to get Senior back under her dominance and control. She simply came to sit next to him, first took both his free hands into hers’. She stated what a shame they so want you, why can you not Senior take the responsibility for them? She placed his hands on her pair of comely sized breasts, holding both there with one hand while the other reached for his still half erected cock. Frank-no as Senior conditioned to that touch if hers’ started to erect again.

Reducing the available blood supply to his brain, his voice box free of the plug began to make noises of pleasure Frank has been denied. His hands on the Directors pair of breasts are groping them, firmly with that grip repositioning the Matron Director moving to be on her knees between his seated legs. The Director complying for one of those noise is Senior’s calling her “Mistress” repeatedly.

The Director thinking yes I am regaining control as his mistress all I have to do is let Senior lead himself, besides she is herself sexually aroused at the thought this rare stallion will be hers’ to control.

Frank now is able to French kiss again and does so with the not so unattractive Matron. Whispering when breaking for air “Misstress-Mistress.”

The Matron locked with tongues feels Senior move his grip to her wrists to bring them behind her back, where she hears a click. Frank has handcuffed the Director, pinned her arms for the first time behind her back. Frank whispers mistress relax you are in control; relax as this time he stands to put the cock into her open lips. Senior is repeating the key word control over and over has he inserts his cock into her mouth soon to be down her throat just like so many she has done before.

The Matron Director of Livestock Training has experienced with the plug to get a feel for it, to better understand how it feels to those she is victimizing. This is the first time she has had a stallion’s enhanced cock in her mouth and now going down her throat. She is still under the illusion that she is in control, but that point of control passed to Senior when he repositioned her on her knees. The Director‘s libido is aroused to a level she has never known, exceeding the arousals with Senior. This level of sexual arousal has blanked out her very thoughts. Her panties are wet and a spot of that wetness is spreading to her rear skirt. Quickly Senior withdraws the cock to smoothly replace it with a club standard plug before the semi-vacancy clears in her pair of eyes. Was then the direct fully realizes she has lost control.

Frank while stripping and tacking the Matron Director explained you are responsible for your present state. You were to one who explained everything in those private lectures that you never thought that livestock could understand. Then after leading her over to the coupling agents announced time for a change of Directors. During these last months in my opinion the present director here is a danger. She does not truly understand those of us with a bent for pony kink, for she has never experienced it herself.

Today you are the pony Matron, for with your sucking of a stallion’s cock and being plugged as you said, “once a pony always a pony.” Now I am going to hitch you where you can witness what is going to be your learned future sexual activity.

Aftermath

At a much later time in a different state in the countryside not anywhere near a population center of any size, on a private homestead the closest neighbor twenty kilometers distant. Frank is in the outside paddock set up for this activity with Arabian mare Springtime her rear hindquarters to him, communicating her natural feelings to her two legged upright human stallion as she sends him a private tight muscle cock hug during their coupling. Plus in her muzzled mouth a fake mushroom like horses cock dildo the mare learned while still at the club before her mating with her stallion to take down the throat into her long neck instead of a bit is being hugged on both sides about her long neck by her human two legged ponygirl stable mates. Girl Springtime, and pony girl April. Who are next up to couple with their stallion, they also rhythmically in a spasm, cheeks sucking and throat swallowing their plugs. Hands, arms now free they could remove the plug, except for the fact they find that pacifier provides comfort and it is now a natural state to have that pacifier to suck on. For it helps maintain the ponygirls constant state of arousal, filling the mouth void along with the rectum tail plug and dildo in her vulvas opening of her vagina which is required to keep up with her stallion.

Frank has resolved, merged the psychosexual mind set he had to adapt to endure the corruptive program of the Silver Saddle Hills club, with his remaining humanity to become a true human stallion, it is well as there are seemingly three devoted pony mares that have also adapted to satisfy and servicing their now existing demanding high powered sex drives. Together they do keep up with each other. Besides the details of daily life, they have a demanding daily physical exercise routine for the energy and vitality it brings them. They carefully monitor their diet to maximize their health. Last they continue to ingest the drugs and hormones that maintain what they have become physically and mentally, a human stallion with a harem of three ponies. The heard is happy, healthy, and well matched to each other.

At their private homestead wearing only the tack they are comfortable without clothing, bare as livestock should live, during those days many times the four pairs of eyes become bright in the vacant waves of pleasure they feel among each other, the mare’s lips suck and her long neck rhythmically spasms on her pacifier and who’s to say she is not imaging it to be her mated two legged human Stallion’s, while her sex fluid drips down her hind quarters, due to the intercourse with her mate for life.

The two girl mares also with eyes bright in waves of pleasure lips wrapped around the sealing plug, cheeks shaft sucking and throat swallowing down the mushroom head inserted, in their rhythmic spasm on their pacifiers and both desires it to be this way for it leaves them open to him elsewhere and as it further arouses their dripping sex fluids ready to be penetrated from his fingers at her lower lips to see him sharing, just not doing it to them.

What Frank as Stallion Senior is sharing each time is how seeing all of his mares mouths plugged in their rhythmic spasm of arousal, eyes bright as his are in waves of pleasure. His stallion’s cock into one of them his hands free to fondle and masturbate the remaining next to be mated all of them can see their bright semi-vacant pair of eyes looking back at him.

Sharing being voiceless for the void of his mouth plugged with the mushroom head of his pacifier deep in his swallowing throat, cheeks sucking the shaft in his automatic spasm of rhythmic arousal cycle.

All lost again, brains reacting on their bonded for life pure sexual instinct, eyes brightly vacant seeing only each other, four bodies locked together with two pair of free forelimbs in a similar macro rhythmic spasm, like the micro individual one induced by the dildo plug, vacant lost in their pleasure, continually many uncounted times a day.

The End
