Phil never ceased to be amazed how quickly the ponies learned, her early days had been with four leg ponies and they had been stubborn as mules, she held out a sugar lump and Jen ducked down to snaffle it.

"You did very well as an amateur on the Saturdays but as a professional the big difference is the Sunday, Cross Country, and if we go international the Carriage section"

Jen flashed her a quizzical look.

"They do a lot of Carriage work in Eastern Europe and the Far East so each summer when we have the International Pony-Girl show all four disciplines are catered for, but you need a podium at All America to get there."

Jen saw a diminutive Oriental Girl approaching in riding gear pulling a small cart with one hand.

"This is Su Li your handler for the Carriage class, you have all the relevant tack so stand while she hooks you up then trot round a bit get the feel.

Jen stood, quietly.

"She bloated and her hair grow Uggh, I do wax later yes?" Su Li asked.

"Yes, she used to shave," Phil explained.

"She like Girl?" Su Li asked.

"Not yet, she was Jack Newbold's fiancee," Phil added.

"Ah" Su li agreed.

Jen found the cart strange, she had to step sideways to turn, the cart kept her straight and her collar stopped her turning her head she relied on peripheral vision.

The ring had a number of obstacle, the challenge a clear round without Cart or Pony knocking anything over. she felt the cart striking obstacles and tried to run wider

Su li climbed aboard the Carriage, Jen barely noticed her weight, she could be only four and a half stone and she followed Su Li's instructions, to achieve a clear.

"Proper way is with blinkers" she fitted the blinkers to the harness and suddenly Jen's world was a tunnel, she could not judge where to turn, crash, they hit a marker, slash, the whip, correcting her.

"Wait for command, don't think obey," Su Li ordered.

Jen ran on mind focussed on Su Li wishing only to obey, to be spared the whip.

"That OK, now blind," Su Li altered the blinker setting and Jens world disappeared

She trotted carefully then Su Li encouraged her with the whip and she cantered then ran, learning to trust Su Li.

Saturday was quiet, Phil was Judging at an event upstate, so Su Li used Jen and the cart as transport to check the Cross Country course, the hills proved tiring and soon Jen was sweating profusely, they returned at mid day and Su li fed and watered her, at the water trough leaving her attached to the cart.

"Take a knap, Su Li ordered flicking the blinkers shut.

Jen drifted into a deep sleep, sleeping while standing now came naturally, she had no idea Jack was standing inches from her, this beautiful animal with matted blonde hair, ugly pubic stubble, covered with dirt and dust, could this be the woman he had so recently worked with.

His Cock stiffened

Su Li shook her head and they walked out of hearing range.

"Phil say no Fuck till after next weekend, then only if she get podium," she explained.

The afternoon dragged, Jen lay in the dust, doing nothing, standing in the hot sun, A man came, she felt something at her crotch, fabric then something hot sprayed on, they were waxing her, in the open, in full view, the pain was intense as the strips were removed, but Su Li's whip slashed calming her, she suddenly felt naked, but Su Li harnessed her to the Cart once more and leaped aboard and they hurtled down the paddock before returning more sedately.

"One last piece then you know all tricks for Carriage pull," Su li promised as she fiddled with her ear, the sound suddenly distorted, she came around the other side, "Ear Plugs, so be sure you obey whip and reins, no see, no hear all is feel"

Jen Trotted on she feared a tree was right in front but soon the comforting slap of the whip told her Su Li was still there, the tug of the reins a comfort Su Li was now her eyes and ears and Judgement, she could truly relax, she felt so calm, running blindly naked yet the inner peace spread a warm glow through her, She and Su Li far closer than she and Jack, like relationship between man and dog, perhaps she thought.

The ear plug moved, "Su Li loves her little Pony, I call you Sue Lee too now"

Jen stamped twice, Yes, Sue Lee and Su Li.

Evening came, and darkness, Jen, Sue Lee as she now was, stood waiting for sleep but she saw lights, a torch. Su Li. Su li opened her stall and led her out, out into the moonlight.

"This is naughty but I want to do it" Su Li whispered.

Extra tack lay by the water trough, leather with a dildo, a strap on? Something extra to go around her breasts, wider stronger and something metallic each side hanging from the waist belt.

"This modified pony boy tack, be careful with me, I ride you, you pleasure me much OK."

Jen stamped twice and watched as Su Li stripped naked then using the water trough as a platform climbed aboard, Jen heard Su Li's gasp and realised she must be riding on the dildo strapped to Jens back, she felt Su li's hands beside her cheeks her breasts against her back, her naked feet in stirrups against her thighs,

"Run for me my beautiful lover, make me so very happy, make me come, do it for me," Su Li pleaded.

Jen felt the love flowing she jogged carefully then speeded up the rhythm sending Su Li bouncing up and down,

"Thats it oh my god, keep going, don't for gods sake stop Ohhh" Su Li gasped before she flopped exhausted as Jen brought her back to the trough.

A shout rang out "You Naughty Girl," Phil was back. "You know you shouldn't do it, now relieve Jen and put her away," she stormed. "No second thoughts, ill do it."

Jen found someone washing her crotch, she forgot how dirty she must be, then realised how aroused she was, fingers explored, then the tiny hand slipping inside her.

"I said I'll do her Su Li" Phil ordered but Jen was already squeezing Su Li's wrist with her cunt muscles and clearly enjoying the experience.

Jen shouted out but the sound was muffled muted like a horse whinnying in pleasure as she clenched and unclenched her muscles.

"I call her Sue Lee, like General Lee." Su li announced.

"Yes, I think that's good." Phil agreed, "we had better get her loosened up."

Su Li led Jen back to her stall, still with her fist deep in Jen's cunt, Su Li walked backwards with Phil's guidance until she was was just outside the stall, Su li withdrew her hand leaving Jen frustrated and Jen eagerly stepped into her stall, the beam was lowered and as Jen waited in anticipation she was disturbed to find the dildo pressing against her anus instead of her cunt, Phil pressed the lube treadle and operated the hydraulic lift to raise the A frame into position, Jen screamed, her body was seemingly being torn open. but gradually and excruciatingly painfully she sank down.

The tears flowed down her face leaving trails in the dirt, and she tried to remain still, but the intruder filled her so completely that she had to readjust her position, she felt damp, she realised she had wet herself, or was it cunt juices, she didn't care, her bum suddenly felt nice and filled, somehow safe, and the more she squirmed the nicer it felt.

Phil and Su Li left Jen for an hour, then they lowered the A frame and released Jen, she staggered slightly but Su Li quickly changed the Dildo and as Jen silently screamed once more they raised it into position again.

The pain was unbearable, Jen almost passed out, the dildo was huge it pressed on everything, her bladder, it even pulled the skin taut over her clit, in fact every tiny movement irritated her clit, she relieved her bladder, which relieved the tension slightly but she could not help herself and before she realised she was thrusting up and down, forcing the dildo in and out of her ass.

Su Li waited for Jen to cum but she seemed incapable, so she carefully fitted the earplugs and put felt pads inside Jens blinkers to blind her before leaving Jen's whole consciousness devoted to the pain and pleasure of her anus.

Eventually the dildo became loose, Jen flopped against the harness which Su Li had secured overhead, and she slept.

Training continued, Tuesday saw a change of routine as the vet checked her arms, she found them too painful to move but they looked good, and they sorted out a seat for her, Ponies have to travel on their fronts to avoid damage to the arms so foam has to be shaped to spread their weight evenly, so they use the same foam system as a Formula one car, fill a bag with foam and lie on it till it sets.

By Thursday afternoon the seat was ready, the Ford panel van bearing the ranch Logo pulled up, the seats leaning forward at 45 degrees, the centre one labelled "Sue Lee" the driver guided her in, adjusted the height, tightened a belt round her waist and went to shut the door,

"Does she need plugs?" he asked.

"Yes better," Phil replied.

The driver opened a locker and pulled out a tapered plastic rod, wiping it on a rag he thrust it up Jens slightly moist cunt until it filled her, and she felt something against her crotch and it withdrew.

"Number three and," he said as he plunged it into her anus, "Number six."

Phil recorded the sizes as the driver lubed the correct plugs and forced them into her.

"Its funny, the way them look human yet shit like animals," he observed.

Jen was hurt, how dare they say that she did not shit like an animal she used proper bathrooms, then the realisation, there were no bathrooms. She was not even aware when she was doing her business, had she lost her mind. The foam gripped her breasts, she felt the warmth, and she felt gloriously full below and the swaying of the vehicle, she could see the road ahead, she vaguely remembered something about it but the pleasure in her crotch was a much nicer thought.

They drove for an hours acclimatisation, returning towards evening, they released her and led her to the wash area by the barn Su Li removed the rear plug and soft shit oozed onto the floor, she eased the hose pipe in an inch or two and Jen recoiled in shock at the cold water as it flushed her out, then the front and wee emerged in a gentle trickle.

They led her to the trough and left her, with ear plugs and tunnel vision from the blinkers she felt lonely, she wanted to be told what to do, she fretted then went exploring, she found a short post near the fence, it had a smooth rounded top.

She played with it finding it slightly too tall to step over easily.

"She found it" Su Li and Phil watched as the pony realised the possibilities

Jen raised herself on one leg and sat down on the post, it slipped easily inside her then she set her own favourite rhythm and started to gallop towards orgasm, gradually the workers stopped their work to watch as she writhed in her private ecstasy yet watched by so many.

"She no good for man after this," Su Li observed.

"I think you are right Su Li," Phil agreed.

Rebekah was out of her depth as a PA. Jack quickly realised how much he had relied on Jen but Rebekah was willing enough.

He approached personnel

"Its not working, can you find someone else," he asked.

The office grapevine did overtime, and Rebekah stormed into Jack's office.

"So what did I do wrong?" she asked.

"Nothing, it, well it's not working is it?" he explained.

"You 're not here, dreaming about her, that's the problem," she protested, "I guess she would drop her knickers for you at a moments notice and you think I wont!"

"Hey, no that's not it!" he defended himself.

"Well I can't drop my knickers because I left them in my drawer," she announced, "If you want me I'm yours"

"Oh Becky come here," he said reassuringy.

He intended to comfort her hold her but his hand strayed to her hot buttocks then the bud of her arsehole and soon his fingers were sticky with her juices.

"Guess I got carried away there." Jack apologised.

"For god's sake don't leave me like this, do something" she implored and was relieved when he dropped his pants and entered her,

He came it seemed in gallons.

"I should have done you sooner, sorry, we'll do it first thing tomorrow or I could come home with you," she offered.

"I'd like that, how about in the elevator, in the morning" he suggested.

"Oh I never done that before!" she giggled.

Suddenly the tension had gone and the work flowed smoothly.
