Effie was living the good life. She had married an older man who was very wealthy. She had managed to get everything she wanted out of her husband. Things were looking up for her - until she met Sam. 

Sam worked for her husband. What he did, exactly, no one knew. Her husband described him as a problem fixer. Sam was big and lean. Effie took one look at him and started to get wet between her legs. She had had numerous affairs since marrying her husband. She always managed to wiggle her way out of getting discovered. She set her mind to figure out how to have Sam and keep the gravy train going.  

One bright Monday morning, with her husband away on a trip, Effie saw her chance. Her husband had always told her to call Sam if she needed help. Effie let the house staff have the morning off and called Sam. Sam was there in ten minutes. Effie met him naked at the door. Things got hot from there. When Sam left, Effie was satisfied.  

This started an affair. At first, Sam did just straight sex. Gradually, he introduced Effie to a whole new world. The first time he bound her she was spread-eagled on the bed. He used scarves to minimize bruising. Effie soared as Sam went to work on her helpless body. She had the most intense orgasm of her young life. Slowly she was introduced to more stringent bondage. On some days, Sam led a bound and gagged Effie outside. He bent her naked over the hood of his car and had sex with her. He sat at poolside while a bound and kneeling Effie performed oral sex on him, and the maid brought him a beer. Bound to a pole in the garden, Sam had whipped and sodomized her as the grounds keeper and his wife sat having their morning coffee, and watched. 

So wrapped up in what was happening to her, she never thought about how odd it was that Sam could take her anywhere on the estate and perform any sex act with her and no one told her husband. Her husband, on the rare occasion that he was home, never suspected a thing. She didn't think it was strange that her husband never was home. In fact, she was happy that she didn't have to put out for him. After all, he was not as much fun as Sam was.  

Sam had been coming over everyday now. She looked forward to his arrival. If he was late, she began to worry. One day, he didn't show up, and she became ill with worry. She had done some studying on the net and found websites with exciting stories of women becoming sex slaves to their lovers. Though Effie never read books, when Sam handed her a copy of 'O', she read it in one night. Then he had her read the 'Beauty' series. Effie read everything, her excitement growing. She was certain that Sam was going to collar her and take away from her mundane married life.  

When Sam came to pick her up one morning, she knew that this was it. By the time the day was over she would be Sam's sex slave. Sam took her to an expensive restaurant. She ate lightly. Her excitement robbed her of her appetite. After lunch, he drove up into the hills. For 2 hours, he drove deeper into the sparsely populated area. Effie fell asleep. When Sam woke her, the car was parked in front of a medium sized stone house. She thought that this must be where Sam lived.  

As she started to get out of the car, she felt a needle prick her thigh.  

Effie awoke in a cage. It fit her exactly. If she could have seen herself, she would have realized that the cage was suspended only about two inches off the ground. She would have known that while the cage held her limbs, trunk, and head rigidly in place, it allowed access to her crotch, posterior, and breasts. All Effie could do was look straight ahead. A band around her forehead kept her looking in one direction. Black cloth blinders attached to the sides of the head cage prevented use of her peripheral vision. She would have told Sam that this wasn't any fun any more, but her mouth was plugged by a huge foam penis that was pushed to the back of her throat and soaked up the moisture in her mouth. She probably wouldn't have appreciated the fact that she didn't drool. She probably would not have appreciated the cat litter box under her cage in case nature called. If Effie could have turned her head, she would have found a row of similar cages, some of them occupied. All the occupants were young women who had two things in common. They had been married to wealthy older men, and had met Sam. 

Effie heard voices. Her heart leapt with relief - one was her husband, the other was Sam. They stopped right in front of her and continued talking like she wasn't there.  

"How's the divorce going?" Sam asked. 

"Done," Effie's husband said. "I got it annulled. Greased a few palms and the marriage never happened". Both men laughed. "She's off in Europe somewhere." 

Sam laughed, "That's close enough to the truth". 

"You could have made a better profit at an auction", Sam observed. 

"I wanted rid of the bitch". 

"Do you have a buyer yet?" her husband asked. 

"Yep", Sam replied, "wanna do the honors"? 

"With pleasure," said the older man as he walked up to Effie. Effie pleaded with her eyes. If he would let her go, she would promise anything. One look at her husband's cold stare, and she knew there would be no mercy for her. She felt a crushing pain in her left nipple, followed by the same pain in her right. "Looks good", her husband said admiring his handiwork. "Who bought her?" 

"Agatha". 

"Agatha! What does a witch need with a slut like her?" her husband asked, pointing his finger back at the caged and helpless Effie. 

"Hey" Sam proclaimed, "wrinkled up old crones need sex too, and she is still trying to grow a tail on a ponygirl and wanted to experiment on a redhead."  

Both men laughed and walked off leaving Effie suspended in her cage with a "SOLD" sign hung from her nipples. 

=-=-= 

Effie remembered Sam and his helpers manipulating her cage. She felt her arms being lowered to the side. She felt her legs being closed. All this time, she had hung helpless in her cage. She could only look straight ahead. She didn't know the sign that had hung from the nipple clamps said "Sold". She had heard her husband say that their marriage had been annulled. She was alone and helpless. She had been in this cage for 2 days. Her keeper had given her water but no food. Effie was hungry.  She realized that hunger was maybe the least of her worries. A steel door was clamped to her head box and closed. Effie was now sightless, too.  Her next sensation was pain. The nipple clamps holding the sign were pulled off.  Effie wanted to scream; but the gag effectively muted any sound and soaked up any loose moisture in her mouth, leaving her throat dry and sore. 

Outside a wagon pulled by two male human ponies waited.  Agatha, the witch, checked the sun. It would be evening soon. She didn't want to spend the night here on this plane.  

Finally Sam and his female slaves appeared carrying a cage containing her most recent purchase. They strapped the cage to the floor of the wagon. Agatha threw a bag to Sam. Sam pocketed the bag, and with a salute, he waved goodbye. Agatha swung her whip catching the buttocks of both ponies with one strike. The males took a strain on the yokes. Slowly, the wagon gathered speed.  Agatha snapped her whip ahead of her team. A portal opened in the solid mountain face. Her, the dray team and her cargo disappeared. The portal closed behind them. 

The journey back to Agatha's place was uneventful. The powerful males pulled the light wagon and its rider and cargo easily over the level terrain. Arriving home, the party was met by a nude woman who clipped leads to the males' collars and held them steady. Two more females unloaded the cargo onto a hand truck and wheeled it away. 

Agatha walked to the front of the team. She petted the two sweating males. Holding out sugar cubes, she allowed the males to nuzzle her hand and take a cube in their mouths. "They have performed well today", she told the woman holding the leads. "Give them an extra ration tonight. Tomorrow, we'll let them get some relief". Slowly she stroked the nearest male's penis feeling it strain against the confining mesh. The male snorted and pawed the ground but didn't move. Amused at how quickly the male became aroused, Agatha left the team and went to check on her latest purchase.  

Effie felt her cage being hoisted. She heard someone working near her. The front half of her cage opened, a hood quickly covered her eyes cutting off her sight, and she almost fell out. Strong yet feminine arms caught her fall and gently lowered her to a table. After two days rigid confinement, Effie's limbs refused to work. Hands massaged the circulation back into her limbs. She felt the tingle as full circulation returned to her feet and hands. Hands lifted her to a sitting position. She felt a cup of water touch her lips. Gratefully she drank the entire cup. Finally the exertions of the past two days overcame her and she fell asleep.  

Effie woke up with a start in total darkness. The events of the past three days had come flooding back into her conscience. She tried to sit up; then realized that she was chained by her neck to the table. She found out she had limited movement of her hands and arms but not her feet. Her ankles were chained to the table as well. She heard a voice say, "Get her up, feed her and bring her to the lab." Effie felt the weight leave her neck. She was pulled to an upright sitting position. The hood was removed. She saw two women. One was holding a leash attached to her collar. The other was attaching a chain to her ankle cuffs. A pull on her leash signaled Effie to stand up.  

Effie was allowed a few steps to accustom herself to walking shackled. The chain limited her step to about twelve inches. Slowly, she was lead to a table and told to sit. A platter of vegetables and bread was set in front of her. Four days ago, she would have turned her nose up at the food. Now her hunger overcame any resistance she had to vegetables. She ate with gusto washing down mouthfuls with draughts of water.  

Her meal finished; her handlers returned. Her hunger satisfied, she attempted to ask questions. She realized that while her mouth was moving, only a whining sound was coming out. She had somehow been robbed of her ability to speak.  

She was lead to a room that looked like a hospital operating room. The two women lifted her and laid her face down on the table. Straps pinned her down. The collar was removed and a broad leather strap covered her mouth. Her head was held in a clamp. 

She was left alone. 

Effie heard someone behind her. She felt fingers feeling the small of her back. She felt someone cutting her hair. Something cool and wet was being applied to her scalp. She felt the scrape of a razor. After her head had been shaved, she felt a sharp pain in her scalp. At the same time, she felt a sharp pain at the base of her spine. Without any relief, someone was stitching the incisions on her head and backside.  

The two women returned. They helped Effie from the table. A collar was locked around her neck. A bar with two wrist cuffs was attached to the collar. It held her hands away from her body. One woman clipped a leash to the end of bar and Effie was led off. She was taken outside. A harness was placed on her head. She was hooked to a carousel. The rest of the afternoon, she was forced to march around in a circle. That evening she was led into a barn.  

In the middle of the barn, two women were bent over, their heads and arms locked into stocks. Their bodies strapped to what looked like sawhorses. From a stall, one of the massive males was led in. Tightly bound and gagged, his erection swung in front of him. Without ceremony, he was led up to one of the females; his handler positioned his erection for penetration. On a signal from his handler, the male pushed. The helpless female moaned as the male began a steady rhythm. The female despite being bound attempted to push back. Suddenly the male roared through his gag. He pushed hard shoving the female's shoulders against the stock. He went rigid. For long seconds, the two remained motionless. Then the male relaxed. Sated he was led to the front of the female where she cleaned him with her tongue. Then he was led off. The other male was led in and the tableau was repeated with the second female. 

Effie watched in fascination. Despite her predicament, she felt the heat rising between her legs.  

Afterward, she was led to a stall. After removing the bar and cuffing her wrists above her head to the bed frame, she was strapped face down and covered with a light blanket. 

Morning came early for her. Her handler unstrapped her and led her to a shower stall. There her wounds were carefully cleaned and examined. She was allowed to expel waste into a drain. Her handler didn't seem to mind this and cleaned up after her. Her wrist cuffs were locked to a chain locked around her waist. Effie was led to a bar about waist high. In front of her were a bowl of dry cereal and a bowl of water. Unable to use her hands, she was forced to pick up the grains with her tongue. She found that by standing on her toes she could bend over and easily reach the bowls. Effie finished her meal and waited for her handler. Bound and shackled there was little else she could do.  

She was led back to the carousel. This time another nude woman was attached on the opposite side from her. Effie strained to see the other woman, but her collar and harness limited head movement. The carousel started and Effie was left to perform the same high stepping march she did yesterday.  

As the morning drew to a close, the incision on her head started to itch. Then the incision at the base of her spine started to itch. Unable to reach either spot with her hands, Effie began to cry in pain. The itching was becoming unbearable. Her handler stopped the carousel and examined her incisions. She left and soon returned with Agatha and a woman in a white coat. The woman in the white coat pulled back the bandages. At the base of Effie's spine, dark red hairs had begun to spout. The hairs were about 2 inches long and growing rapidly. From the incision on Effie's head, the same color hairs were growing. The woman in the white coat rubbed a cream on the areas and the itch subsided. Agatha and the woman in the white coat congratulated each other and walked away. The handler started the carousel up again and Effie resumed her marching not knowing she was growing a tail and a mane.  

For Effie, the days passed without change. She fell into a routine of sleep, eat, and train. She went from the carousel to pulling a weighted sled. Her strength and endurance grew. She was finally harnessed to a sulky and trained to obey the slightest command. All this time, her mane and tail had continued to grow.  

=-=-= 

She had been the first. Agatha and the woman in the white coat had grown wealthy and famous because of the success of Effie's operation. They had performed the same operation numerous times. Now virtually every human pony in the land sported a growing mane and tail. There had been an unexpected beneficial side effect to the procedure. Effie sported a short downy fur coat that covered her body except for her palms and the soles of her feet. The coat kept her warm in the winter and protected her from the sun in the summer.  

Effie stood waiting for her mistress. Her long tail and mane swaying in the wind. Her previous life was a distant memory. Her wrists were chained to the rails of the light sulky. A hobble prevented her from kicking. A light chain attached her nose ring to a ring set into the stone. Her fine leather bridle and silver bit spoke of her station in her mistress's stable. 

Right now, two of Sam's friends were admiring her. One lifted Effie's heavy breasts by the solid silver rings that pierced the nipples. The other felt the solid silver rings that pierced her labia. Both had petted her downy fur coat, felt the mane and tail and felt the smooth powerful muscles that Effie's constant training had developed. Bitted and hobbled, she suffered these indignities without the ability to protest. 

Inside the cave Agatha was purchasing another product of Sam's handiwork. Effie looked at the sun. She wished her mistress would hurry. Neither one wanted to spend the night on this plane.
