It’s good to be independently wealthy. To have financial security in one’s early thirties is a great feeling, not to mention having the ability to pursue one’s interests without worrying about deadlines, kissing up to the boss, or having to commute to work. On the other hand, there is the freedom – or should I say temptation? – to indulge in whimsies that one normally wouldn’t give a second thought to.

My beautiful wife Diana and I particularly enjoyed spending time on our California ranch. Three hundred acres of blissful privacy, complete with a sumptuous mansion, heated outdoor pool, and miles of trails in the surrounding woodlands ensured that we would never get bored. Or at least we wouldn’t get bored very often…

Diana and I had experimented a bit with pony play before that summer. Seeing her trim 28-year old body and luscious curves held tight by black leather always got my pulse racing. But turnabout was always fair play, as she liked to say, so I had to take my turn in the tack we had specially made for ourselves. Not that I minded one bit.

That spring Diana had broached the subject of trying out a dual pony play fantasy, one that would last more than a few hours. The suggestion intrigued me but it was a bit of a challenge to figure out how both of us could be in pony restraint simultaneously without forcing us to intrude a third party on our little game. There was also the issue of how long the fantasy should last.

“What kind of a time frame were you thinking of, dear?” I asked as we lounged by the pool.

“Oh, Mark,” she said playfully, “I don’t think you could last more than a week at any rate.”

“Just a week?” I retorted, “Why not two while we’re at it?”

“You surprise me! Why not make it a true test of endurance? How about a full month?”

I never could resist that smile of hers.

Setting up the scenario took weeks of planning and more money than even I would care to admit. The house and various outbuildings had to be rigged with computer systems so that they would maintain both themselves and us during our period of enforced helplessness. Being the cautious type, I ensured that food, water, and other supplies were more than ample for the time we would be in restraint. Diana insisted that all temptation to cut the game short should be removed, so the computer system governing the house was set to lock down the property for the month. Once the computer in the enclosed patio was set, no one could get into the house or past the fences surrounding the property until all the time had elapsed. Such finality made me a bit uncomfortable, so I rigged a failsafe mechanism to be used in an emergency. Several alarm buttons were set up, that even a pony could trigger. Upon activation, an automatic S.O.S. would be sent to local police, firemen and, incidentally, the press corps, requesting assistance. Naturally, neither of us wished to be exposed (no pun intended!) to public scrutiny ensuring that we would only use this system in case of actual emergency. Fortunately for us our accountants and other business assistants were used to us taking a month or three off on frequent vacations, so our absence wouldn’t arouse any suspicions.

Finally, the fateful day arrived. Having put everything in order, we had our last dinner as human beings for the next four weeks and then got together in the enclosed patio with all our gear. First thing we did was strip down, piling our clothing in neat bundles. I looked over my wife’s lithe, athletic frame, something I never got tired of doing. We were both in pretty good shape although neither of us were heavily into athletics.

I assisted her with her leather harness. First a strong belt around her waist, which was connected to a strap that passed up her chest, between her medium-size breasts, and connected to a thick leather collar that I fastened around her neck. Smaller straps ringed her torso, ensuring the harness wouldn’t come off. One strap ran under her breasts, with small partial cups that gave her sufficient support, yet did not leave her any less exposed. Two more straps ran from her hips on either side of her shaved pussy; where these came together a thick butt plug with a long horsehair tail was attached. After applying plenty of lubricant I managed to insert this without much problem, although Diana gave a grunt of protest. The strap continued up behind her and attached securely to her belt. More straps encircled her shoulders and I fastened all of the clasps extra tight. Diana was not slow to repay the favor when I put on my harness, which was very similar except that mine had no breast cups (naturally), but had a circular strap that fit snugly around the base of my cock, constricting it fairly severely.

Trying to ignore the sensations around my nether regions, I then turned to the boots. These were custom made to fit our feet, and were in the shape of horses’ hooves. A large arch was engineered into the boots, ensuring that we would have to trot on the balls of our feet. Sophisticated absorbers distributed the weight so that we could walk in the boots for long periods without discomfort. They came up to mid-calf, and after tightening the straps around our ankles, would provide secure footing.

Then it was time for our head harnesses. Each consisted of a strap that went around our forehead, with further straps leading down each cheek that were connected to a heavy bit. Further straps around our chin and the back of the head made sure the harness would not come off. Finally, the whole assembly was attached to our collars. Much time had been spent designing the bits. They were well-padded so that our jaws and teeth wouldn’t become sore, and they had a tab that protruded into the mouth, depressing the tongue and prohibiting any intelligible speech. The bit was partially hollow, and holes in the front allowed the passage of air for free breathing as well as the attachment of tubes for drinking. We gave each other one last, long deep kiss before attaching the bits, as it would be some time before we could do so again.

At this point we were almost ready to proceed, so I set the timer on the computer to lock down the house and grounds in ten minutes. The computer screen could be easily seen from outside the patio, and would display the state of the system constantly, so that we would know if there was any serious problem. Once the computer was activated, we quickly put on our forehooves. These gloves were similar to our boots, each ending in a horses’ hoof and extending up our forearms. A padded crossbar inside the hoof gave our hands a strong grip, although of course we couldn’t pick up anything once they were attached. An automatic latch would lock the hooves around our hands until it was deactivated by the computer system four weeks hence. With one last look into each others’ eyes, we closed the latches and passed the point of no return. We quickly exited the patio and trotted out onto the grass outside.

As we walked, I was very aware of the sensuous feel of the leather against my skin. Since we were planning to wear our harnesses for many weeks uninterrupted, precautions had to be taken against chafing or irritation. Our gloves and boots were made of a composite material that allowed the passage of air and would keep our hands and feet dry. All the leather in our outfits was impregnated with an oil that would be slowly released over time in order to keep our skin soft and unblistered. As the evening breeze blew over my nude body, I felt incredibly alive and free.

It was about 80 degrees out as we descended the lawn behind the house toward the stables we had set up. The setting sun illuminated the trees surrounding the property, creating an exquisite mix of yellow, green and blue. My gaze shifted to Diana, taking long strides in front of me. Her muscled thighs, taut buttocks and smooth back, all imprisoned by yards of black leather, triggered a fire in my loins, and my cock was quickly bolt upright. As we approached a wooden fence in front of the stables, I quickly ran up from behind, pushing her against it. She let out a muffled yelp of surprise as I nudged her legs apart with my own. She quickly figured out what I was on about, and by the wetness gleaming between her thighs, I knew she had the same thing on her mind.

I moved my head around her side and nuzzled her breasts, regretful that I couldn’t nibble and lick her rapidly hardening nipples. I planted my forehooves on the fence on either side of her and rammed my cock under her tail and into her pussy, forcing from her an animalistic groan. As I plunged in and out of her I instinctively tried to cry out, but the only thing that came out of my bitted mouth was a whinny that resembled a horse’s neigh. We sounded like two animals in heat as we moved in time with each other with a rapidly increasing sense of urgency. I quickly came to climax and shot my load into her warm depths, both of us shuddering in the most intense orgasm either of us had had in months.

We stood there for some time in the deepening shadows, I still inside her, enjoying the feel of warm skin on warm skin. Suddenly, our reverie was broken by a light shock and buzz within each of our asses. Damn! As part of our ‘pony training’ the computer in our house was programmed to keep us on a rigid timetable, and it was now signaling us that it was time to go to bed. We quickly trotted towards the stable, urged on by occasional shocks gradually growing stronger in intensity.

The stables were lit only by a dim bulb in the ceiling, but we were able to make out our stalls inscribed with our pony names: Galahad for myself and Starlight for her. I wasn’t crazy about the name but Diana had insisted. As we entered each stall the doors latched behind us, keeping us in until morning. Thankfully, my ass no longer felt like it was inhabited by an ant colony. Each stall had a pile of hay for us to sleep on, a water bottle configured to fit our bits to drink, and a special toilet facility. Upon seating oneself, an arm removed one’s pony tail to allow proper evacuation. However, the arm would also prevent one from rising from the toilet. Once the toilet was flushed, the arm would reinsert the plug and release the pony. It was a bit embarrassing to have to go to the bathroom in front of Diana, but I figured I would soon get used to it.

We were a bit keyed up from our lovemaking and the excitement of our first night as ponies, but locked into our stalls as we were, we could not be as close to each other as we would have liked. Once the timer extinguished the light, we couldn’t even gaze at each other, so we each retired to our piles of hay where we spent a fitful night’s sleep.

Sleeping on hay was less comfortable than I had imagined; it was rather itchy and I had trouble finding a good position to sleep in. Before I knew it sunlight was peeking through the stable door and I got another butt buzz telling me to wake up. I quickly took a gulp of water then used the facilities before leaving the now-unlocked paddock. A few minutes after we left the stable door closed and locked automatically; we were going to be outdoor ponies for the month.

The cool morning breeze felt good after the somewhat confining stall, and we trotted around the large open area between the house and stable for a few minutes, gradually waking up. We took every opportunity to rub our bodies against one another, and were about to engage in another bout of lovemaking when the cursed buzz impelled us to turn our minds to the task at hand.

To prevent us from getting bored, and to emphasize our helplessness, the computer system was designed to put us through a rigorous regimen of training and discipline. For our first task we ran over to a large area covered with dirt about half an acre in size near the stables. At one end was a plow specially designed to accommodate human ponies. We walked up to the plow, which had a wide yoke attached to it. The ends of the yoke fitted into sockets in the back of our harnesses. I quickly touched the two together and heard a loud click that told me the two were locked together. Diana did the same. We would not be released until we had drawn the plow the requisite distance, and any hesitation or slacking on our parts would be met with a shocking reply!

At the first zap we began straining against our harnesses. Since I was stronger, the plow was balanced so I had to do more of the work. My rear hooves bit deeply into the thick loam covering the field, and slowly the heavy weight began to move forward. We had done experiments beforehand to ensure that the load wasn’t too much to handle, but there is a difference between pulling with one’s hands in work clothes and being forced to work in tight restraint at the crack of dawn!

We huffed and puffed as we slowly dragged the plow through the field. It bit deeply into the soil, forcing us to switch to all fours. The hooves on our hands came in handy as we needed all the traction we could muster. Finally, after about fifteen minutes we managed to cross the field. However, that was not the end of our ordeal. I had programmed the system to require no fewer than four lengths the first day, gradually increasing over time as we built our strength. The second length was much tougher than the first, but we managed to grit it out. The third row, however, was pure agony. We stopped to take a break but the pain in our rear was supplemented by shocks in our collars and we managed to find new reserves of strength. Finishing the fourth row was managed through pure strength of will. Sweat was pouring down my body by that time despite the mild temperature and Diana’s flanks shone in the rays of the morning sun. Every pull was accompanied by groans and grunts. When we got stuck, which was often, we had to coordinate our pulling. My attempts to signal her verbally were useless, so we worked out a system of hoof stamps that let us know when to heave. We managed to reach the finish line, whereupon the links to the yoke were released and we collapsed upon the dew-covered grass, gasping for breath. What I had envisioned as a 45-minute warmup was instead an hour-and-a-half marathon. But there was no way to change the program now!

After resting for a while, we staggered to our feet and made our way to the shower station. Our body weight triggered a spray of water from a spigot. I shivered at the impact of the cold water and I could see goosebumps over Diana’s body, but it felt good to wash off the sweat and grime from the stalls. A man-high cylindrical sponge set on a vertical axle was stationed next to the spigot, rather like something one would find in a car wash. Rubbing against it released a flow of soapy suds that felt good on the skin. The soap also included a sunblocking agent so we wouldn’t get sunburned strolling around nude in the hot sun. We began rubbing our slick bodies against one another again but before we got too distracted we rinsed off and began walking around to air-dry our bodies. It was a beautiful day, with sunny skies and warm temperatures, so the moisture on our skin quickly evaporated.

With an inward smirk I let out a loud neigh and began chasing Diana around the grounds. My erect member, constricted by the tight grip of my harness, impeded my movements a bit, but I eventually managed to track her down (she would probably say she let me catch her but I know the truth). I pinned her to the ground and we began grinding our chests against one another. After a while she rose to all fours and, giving me an impish look with her eye, began moaning and swaying her ass in front of me. The swollen lips of her labia told me it wasn’t all an act, and I quickly came to all fours over her body, my chest rubbing against her back. I mounted her quickly and thrust deeply inside her. As I rested upon my forehooves I felt an incredibly primal urge. Here we were, naked yet restrained and bitted, having sex in the open air. The sense of freedom combined with the sense of restriction was intoxicating. Diana shuddered beneath me as a massive orgasm rocked her, and, unable to hold it in further, I shot my load as well. We stretched out on the soft grass enjoying the moment and each other’s presence.

The rumbling of our stomachs interrupted our reverie. This was followed by the sound of a loud bell and we knew feeding time had come. We jogged back toward the stables, not wanting to miss our chance. The feeding area consisted of two troughs behind a partition with two circular holes large enough to fit our heads. Upon inserting my head, an automated arm removed my bit and a pile of feed was dispensed into the trough in front of me. I was tempted to try and speak to Diana, but our troughs were separated and I knew that the feeding was on a strict timer; if I ate too slowly, the excess would be discarded. So I dove in. The feed was nutritious if rather bland: a carefully balanced mix of grains, fruit and protein and vitamin additives. It seemed rather a small amount and was soon gone. The bit was reattached and I was allowed to withdraw my head from the slot. I hoped my nutritional calculations were correct, as we were not going to get another meal that day.

After eating we had a couple of hours to ourselves, so we walked over part of the estate, exploring the forest paths and enjoying the wildlife. Being nude and without hands or speech made me feel closer to nature than I ever had before. Diana stopped frequently to smell the wildflowers that lay scattered over the path. All too soon, however, a familiar pain told us that another task lay before us.

Some distance behind the stables a circular area was laid out, within which was our next trial. If the plow was designed to tax our strength, this next effort would tax our endurance. A pole stood in the middle of the circle with a wide cross bar. From the crossbar descended another bar and a chain that attached automatically to our head harness. Another shock told us to begin. We started walking in a circle around the pole, the crossbar turning as we moved. Our horsetails set the pace for us: if we went too slow they would shock us, with a warning buzz just beforehand. For a few minutes we paced slowly around the circle, which was easy enough, but before long we were urged to a trot, then a gallop, which we had to maintain for a long time. Just as I was wheezing through the gag, the pace slowed again, and we were allowed a moment to recover. I glanced at Diana on the other side of the circle and her breasts were heaving with the strain. I knew I had set the program to run for two hours but it was hard to estimate the passage of time. Just then we had to pick up the pace again, and I soon became focused on the patch of dirt in front of me, endlessly traveling in a circle. Again we were allowed to rest. By now, the day had gotten very hot and we were both panting as rivulets of sweat ran down our torsos. Yet again the pace quickened. It seemed we were required to go faster each time though this may well have been an illusion. Finally, when I felt I could go no farther and I was drawing in my breath with ragged gulps, we were released from the diabolical machine.

After that, we headed over to the water dispenser where I greedily sucked in the precious liquid in great gulps. Afterwards, I was too spent to think about doing much. My legs felt like noodles. We lay together under a tree and fell asleep in exhaustion for a while. When I awoke, Diana lay nuzzled against my chest, sound asleep.

We sat for a while after that, watching the clouds and soaking in the tranquility of the moment. Soon enough, our third trial of the day would be upon us. As the first task involved strength, and the second endurance, the third would involve speed.

We started at the head of a trail that looped and wound through the trees at the back of the estate for several miles. I knew from experience the trail led through brush, up and down the banks of streams, and at one point, thigh deep across a small pond. At periodic intervals there were motion detectors to make sure we didn’t cheat. We had only a limited amount of time to traverse the course; thirty minutes after we started, the stable doors would close and lock. If we weren’t inside by that time, we would have to sleep in the chill night air.

We stretched and warmed up near the starting post. A short beep told us to prepare ourselves. Diana was actually a slightly better sprinter than I was, having done track in college, but neither of us had much experience with a long obstacle course like this one. Furthermore, we still weren’t completely used to our hooves yet. As soon as the simulated pistol shot sounded, we scrambled along the track, Diana in the lead. The first mile or so was over relatively flat terrain, and I felt we were making good time. I even took the time to admire the sexy jiggle of Diana’s butt cheeks as we ran down the path. Once the going got more rugged, however, we slowed down considerably. At one point we scrambled down a bank and across the stream, only to have great difficulty getting up the other side. Without hands or toes to gain purchase, we struggled for some time before heaving ourselves up onto the opposite side.

At another point in the course, Diana strayed too near a marshy area next to the path, and got her left leg buried ankle-deep in mud. It took several seconds for her to work herself loose. After that, we rushed along the rest of the course as fast as we could, knowing that time was running short. We splashed across the pond and as water cascaded off our bodies we rounded the corner into the final stretch. We could see the stable door open in front of us, and pressed on to the best of our ability. Just before we reached the doors, however, they drew to and closed with an ominous click. We sagged against each other helplessly.

That evening was a bit chilly, although not really cold, given the season. The biggest pains were the lack of a toilet and being forced to sleep on the hard ground. We each silently vowed we wouldn’t get locked out of the stables again.

The next day we were awakened by the sun glinting through the trees. All our muscles ached horribly from the intense workout we were subjected to the previous day. I would have liked a chance to relax and take it easy, but before long the insistent shocks from our tails drove us to our daily chores.

The routine of each day quickly passed from kinky, to thrilling, to monotonous. Unable to speak or use my hands; one bland meal per day; driven relentlessly through the same tasks over and over again; by the two week mark I was ready to quit. I would have, if I could, but there was no way into the house to deactivate the system. I had planned things too well!

One positive aspect was the sex. I don’t know whether it was the restraints, the constant physical activity, or my cock ring, but I was almost constantly horny. Diana, too, was as receptive as I have ever seen her. We made love in countless positions: on top of a tree stump, in the grass, against the fence rails, standing in the pool. Each day seemed to draw out ever more intense animalistic passions for each of us.

I began to notice physical changes, too. The constant exertion was making Diana’s legs leaner, and her thighs and calves more muscular. Her breasts also appeared firmer, and with our strict dietary regimen, all traces of fat were rapidly disappearing from her abdomen. She had developed a fine all-over tan, although I figured she would have some very interesting tan lines by the time we were through. She was exquisite, and seeing her glide through the trees on her hooves made me horny as hell.

The days dragged on. I noticed my modes of thought had changed. I now reflexively took up each task as the time came, without the need for my tail to prod me. The constant turns around the pole, and the breathless sprinting down the trail each sunset, had banished almost all thought of the outside world from my mind. I began to think of myself as the pony Galahad, and Diana as my filly, Starlight. I felt that if we were to spend much more time in this state that I might not want to go back to my old life.

Fortunately, our final day was fast approaching. But there was to be one more ordeal before we were freed. Up until that time the weather had been gorgeous, with only a few refreshing afternoon showers to break up the pattern of sunny days. The night before our last as ponies, however, there was a frightful thunderstorm. We were glad to have our stalls and hay piles then! Starlight whinnied a bit in fear at the noise, but I reached a hoof into her stall and stroked her to sleep.

The next day the clouds still hung threateningly over the estate. The plowing field was a muddy wasteland, and the plow buried itself so deeply into the muck that our best efforts could barely move it. The dumb computer had no inkling of our difficulties, naturally, so we yelped with the most intense pain we had yet experienced as we wrestled with the yoke. Our hooves bit deeply into the mid, and we were soon completely spattered with the thick substance. Our improved physical shape gave us enough advantage to finally complete the course, but only barely. Our shower and soap were never more refreshing!

It proceeded to rain on and off with periodic downpours the rest of the day, and we were soon drenched. We dared not seek shelter under the trees for fear of lightning, so we huddled together in a small hollow and took solace that our ordeal would soon be over.

By evening, things looked even worse, and it was apparent that we were going to get a storm that made the one the previous night look like nothing. We were anxious to get back into the stables, but had to wait to be summoned to the obstacle course before we could get in. Finally, the hour came, and we fidgeted at the starting gate. I could see by the expression in Starlight’s eyes that we were thinking the same thing. We had a very stringent time limit to complete the course and get into the stables. With the rain, however, the footing was sure to be treacherous and the mud would slow our pace. We needed to put forward the performance of our lives to make it to the end in time.

At the start of the gun we were off. We breezed through the first two miles; after four weeks of intense training, we were fit ponies and could easily take that distance in stride. Once we came to the streams and gullies, however, we slowed considerably. Our forehooves scraped futilely at the muddy banks and we were forced at times to slither our way up on our bellies. Once on the opposite side we tried to make up for lost time, dodging trees and splashing across the pond. We would be cutting it close.

Then we came to the last stream. The stream was flooding, and the water, which normally was only ankle deep, now raged above waist height on me and chest height on Starlight. If we weren’t careful we would be swept downstream and lose any chance we had to finish in time. We crossed together, I shielding her from the full force of the current as best I could. The other side was a muddy mess. I managed to boost her up with a grunt and a hoof under her shapely butt, but there seemed to be no way for me to get up. I tried to signal her to finish without me but she refused. A large dead tree stood askew on the bank, and she ran over to it, pushing it as hard as she could with her shoulder. Soon, the tree fell and I was able to get enough purchase with its help to scramble up the side of the stream.

The last few hundred yards went by in a blur, as we rushed to make the limit. Soon the stables loomed ahead. We spent our last reserves of strength running toward the door, barely making it inside just as the thick wooden doors closed and latched behind us. We leaned our soaked, muddy bodies against one another for support, but before long our cursed tails forced us into separate stalls as usual. It seemed a fitting end to a grueling month.

The storm raged all night, and we didn’t get much sleep. The next morning the rain abated a little as the sun rose. Just as the stable door swung open one last thundercrack seemed to burst right on top of us, but our shock soon passed and the weather began to clear.

We raced up the path to the house, eager to return to civilization. Long absent thoughts began to re-enter my consciousness: Steak dinners, television, fast cars, a proper bed! I thought we might celebrate with a trip to Paris. However, as we drew closer something seemed to be amiss. I noticed all the lights in the house were off. The storm! I figured the power must have been interrupted temporarily. Sure enough, the lights in the patio soon flickered on. A panicked thought came to me: The computer system! I peered through the glass at the computer screen:

…..System rebooting

….Configuring memory

….Reestablishing program

I sighed with relief. I had set the computer to automatically restart the program in case of interruption. Relief soon turned to horror as I read what popped up next:

….PonyProgramA initializing

….Commencing training program

…..Timer set

Time remaining: 29 days 23 hours 59 minutes

We looked at each other with wild eyes. The timer had been reset! The stupid computer thought we were starting all over again! I pounded on the unbreakable glass with my hooves, hoping to force my way in, but it was futile. I collapsed sobbing on the ground. She moved closer to try and console me. Another month as a pony! More harsh training, more inescapable discipline! My mind couldn’t take it all in.

Then I felt a sharp pain in my ass. Reflexively, without further thought, Starlight and I rose together and headed toward the plow. Another day’s work waited to be done.
