As Aaron stepped out of the barn leading Angel toward the paddock for her morning exercise with the other ponies, he glanced around Black Star Stables. Just a typical morning with Janice hitching up Sable and Raven to the buggy. Boris must be going on a short trip because he always used those two. They made quite a striking pair; both were tall, dark and heavily muscled. On the other side of the barn, a groom sponged down two chestnut colored fillies and held the hose to rinse them off as he went. These two were a bit frisky and obviously needed some exercise because the two fillies kept trying to rub against the groom whenever he got close to them.

Black Star Stables was located on a private island somewhere in the Black Sea but Boris owned it exclusively and used it to raise ponygirls to be sold at auction four times a year. So the ponies were really human women who had been either born and bred as ponygirls or were converted from an outside source. Angel was one of the latter. Just 18 months ago, she was a college student, studying law and political science when she had been drugged and flown to the island to be trained as a ponygirl.

Today was the first day of Angel's career as a breeding pony although the ponygirl had no idea what awaited her. Aaron pulled Angel from the paddock, hooking a lead rein to the ring in her septum and walking her to the vet's office for inspection and evaluation. As Aaron, led Angel into the office, bent her at the waist over the t-bar examination stand, and began strapping her in place, Boris entered with a stranger.

"Good morning sir," Aaron greeted his boss. "She'll soon be ready for inspection and I know Doc wants to draw some blood." He quickly bent down to fasten Angel's hoof boots to the d-rings on the table, spreading her open for the two men.

"Mr. Jeffers, this is Angel who I believe will make a beautiful foal with your stallion," said Boris as he stepped up to gently tug on Angel's tail and stroke her flank.

Mr. Jeffers stepped closer to Angel and reached out to stroke her mane. "Yes the coloring is wonderful. This white blonde will make a perfect match to Thor," he said as he continued to stroke Angel's neck and back. "Is this all natural, Boris?"

"Yes, when I first saw this filly, her coloring reminded me of Angel's wings. That's where she got her name." laughed Boris and he too reached out to stroke Angel's mane.

Strapped to a t-bar, Angel wiggled but she couldn't close her legs or raise herself up to avoid Mr. Jeffers inspection. She tried to pull away and whinnied loudly when Jeffers began his inspection of her genitals.

"Shh little one," murmured Aaron at her head as Jeffers inserted two fingers in her cuny, slowly pumping them in and out until Angel began to lubricate. Then he moved those fingers to her clit and pulled gently on the ring and stroked it until Angel began to pump to his rhythm.

Laughing, Jeffers withdrew and Angel made a neighing sound and continued to wiggle her hips, swishing the tail across the back of her knees. "She is ready for mating, and yes, I think she will make a wonderful mate for Thor. I'd like to drive her a bit before we discuss an agreement." he said as he slapped her flank and walked away with Boris.

Next to Angel, the Doc Robins put the branding iron in the glowing coals and then turned to draw some blood from Angel. "Assuming all the blood work comes back normal and indicates pregnancy is possible, I would recommend denying her release for several days before the stud is brought in to cover her," he told the men as he stroked Angel's flank.

The men left, still talking about their afternoon drives, and Angel was left to finish the afternoon with Doc. She soon felt a prick behind her knee and Aaron still stroking her mane and whispering that it would be over soon.

"Okay..I have the vials I need for testing." said Doc and he took the vials out. Aaron quickly released Angel and hooked the lead to her septum ring and led her out of the vet's barn and back to be tacked up.

Pulling against her groom, Angel protested the next step. She wasn't going to give this cruel man a smooth sulky ride if she could help it. But Aaron just smacked her rump with his crop, once, twice, and she reluctantly moved forward toward the tacking station. Once there, Aaron whispered "Be good now Angel. We'll make you pretty and then you show them what you can do." He stroked her neck and kneaded her breasts to relax her, but he began tacking her up at the same time.

He slid the bit between her teeth and hooked the bridle around her head. Next, he hooked bells on her nipple and clit rings. With each breath or step and merry jingle of the bells reminded Angel of her position as a ponygirl who was controlled by her groom and master. Then he reached for the harness that fit around her torso and pulled on a tight corset around her waist. Backing her into the sulky, he hooked her into the conveyance and signaled to Mr. Jeffers that he could mount.

After climbing into the sulky's seat, Jeffers cracked the whip and a sharp pain forced Angel to leap forward at a brisk trot. Her knees rose steadily, her breasts bounced jauntily and Jeffers kept cracking the whip until her backside felt like it was on fire. As the countryside rolled past, Jeffers watched Angel's buttocks redden and bounce sexily mile after mile. Finally the stable was once again in sight and Angel picked up her pace trying to reach the safety of her stall.

As he pulled Angel into the yard just outside the barn, Jessie came up to take the bridle and unhook Angel from the sulky and Boris joined the little group.

"Well, what do you think? Should we begin preparing her for your stallion?"

"Boris, that is one sweet little mare. I can't wait to see her covered by my Thor. They will throw a beautiful foal."

Angel didn't really understand the exchange, but Jessie pulled on her bridle, leading her toward the grooming station. Angel would soon discover what the two men meant, but in the meantime, Jessica hooked her to the wall using the ring through her septum and turned the hose on the overheated mare.

After scrubbing the sweat and dirt from Angel, Jessie pulled the tail from Angel's rectum while Angel twisted away from her. Casually Jessie wacked Angel's sore backside with the hose until the ponygirl stood still again, and then she inserted the hose into the vacated rectum. As Angel filled up, Aaron came up to watch, holding a strange curved leather chastity belt.

Angel's stomach swelled until she looked 6 months pregnant and Jessie stopped the water but didn't pull the hose. Instead Jessie turned to Aaron, "What's that?"

"We're going to keep this one chaste until she's covered. No more easy orgasms. That way she'll respond to the stallion quicker." he replied.

After pulling the hose and watching Angel evacuate the enema, Jessie hosed her clean and Aaron stepped in to insert her tail and the new dildo into her vagina. Then he put a curved leather piece over her sex to stop any contact that might cause her to cum, and Angel was returned to her stall.

For the next three days, Angel wiggled, pranced and squirmed inside her chastity belt, but she got no relief. Nothing touched her sensitive sex. Aaron and Jessie watched her in the paddock in the mornings, twitching her tail and even rubbing her crotch on a post. They knew how frustrated she was. After months of two or three orgasms a day and constant awareness of her sexual organs, Angel was not prepared for abstinence.

A few days later, Aaron awakened Angel, hooking her lead to the septum ring and pulling her into the grooming station. "Is it the big day?" asked Jessie as she watched Aaron begin to sponge Angel clean and prepare her for her morning enema.

"Yeah, Thor and Mr. Jeffers arrived last night." he replied as he stuffed the enema hose into Angel's rectum.

Finished, Aaron began rubbing lubricant on Angel's sex and finally he docked her tail (he put her tail inside a small bag so it wouldn't get in the way of the stallion's thrusting.) Then he hooked bells on her nipple rings and lead the ponygirl into the breeding barn.

In the center of a ring, framed by mirrors, there stood a t-bar restraint table. Angel was quickly strapped in breed position with her hooves spread and hooked to the floor. She could raise her shoulders a few inches but a strap across her waist prevented her from moving forward or backward. In the mirrors surrounding her Angel could see her open sex and a group of 6 or 8 men watching her.

Angel tested her bonds, trying to pull her legs closed and wiggle out of the strap across her waist. She trembled watching the men stare at her sex and began to cry with fear. Aaron touched her mane and whispered to her to be calm but Angel knew that she wouldn't like what was to come.

Behind Angel a door opened to let Aaron enter again leading a huge ponyboy. The stallion had to be 6'5'' or more with a long cock that was already half erect. Suddenly Angel realized what these men intended for her, and she began to test every bond and whinny loudly in fear. In the mirrors, she could see the men laughing as Aaron stroked the ponyboy's huge cock to a full erection and then lubricate it. Angel's rump wiggled back and forth in her bonds, but strangely she began to feel some anticipation. It had been days since she was allowed to cum so now her body reacted involuntarily.

Leading the stallion forward Aaron released him just as his member touched Angel, and he rammed the tool home. Her docked tail quivered as the stallion rammed into the vulnerable mare over and over. Soon, Angel began pushing back into the stallion, picking up his rhythm and just as the stallion roared with his orgasm, Angel too stiffened as her cunt pulsed around Thor's member. She knew she shouldn't have enjoyed that, but she couldn't help her body's response to the stallions thrusts.

The two ponies, both white blonde and pale skinned, were pulled apart by Aaron who then patted Angel's rump as Thor was pulled out of the barn by his handler. Angel would remain strapped to the breeding bench for the day and twice more Thor would service her.

Several weeks later, Doc announced that Angel was indeed pregnant.
