When Monique met Keko at a singles bar, they hit it off right away. Monique had had it with the male species, and now enjoyed pleasure only in the arms of another woman. Yet Keko was like no other woman Monique had ever met. Never thinking herself submissive, Monique allowed herself to be swept into Keko's lifestyle of bound sex. In less than a week, Monique endured her first bondage session at the hands of her Eurasian lover. Within a month she was Keko's devoted slave. So when Keko invited her to her estate in the country, Monique was more than happy to join her.

On the second night, Keko informed Monique that in the morning she would endure a transformation from female to ponygirl. Monique was a little taken back by the announcement, and Keko informed her that the choice was hers to make, but if she refused she would be driven back to the city and someone else would be found to share Keko's affections. Monique loved her Mistress and said she would endure the ordeal.

The next morning, Monique was allowed to eat a light breakfast and take a shower. She was advised to make use of the toilet, because she would not have access to one for the duration of the day. Then when she was ready, Monique was taken to her new quarters at the stables. Her new home would be a 10 x 10 stall with hay on the floor, and she was introduced to Jason, her groom. It would be Jason that tended and fed her and although she was told that Jason was under strict orders never to fuck her, Jason could on occasions, be allowed to have his needs tended to via oral sex, and Monique was told to do her best to please him.

So it came to pass that Monique was fitted with a boned corset, and a locking chastity belt. Cuffs were placed on her wrists, as was a collar with rings to tether her in her stall. A special head harness was applied with a rubber bit for her mouth. Yet Monique was not prepared for the final two props to transformed her into a true Ponygirl.

Monique's new boots were void of any heel, instead they had a heavy stone hoof with a metal horseshoe nailed to its bottom to force all her weight onto the balls of her feet. Once fitted, Monique was given a little time to learn how to walk or trot around her stall. The last item of business was Monique's "Tail". A matching plume of hair attached to an anal plug was to be inserted into her bottom. There it would stay till Jason removed it. If Monique failed to keep it suppressed with her rectum, she would be horsewhipped as punishment. Monique bent over as her lover watched Jason lube and insert the anal plug inside her. Once done, Monique stood upright once more and was allowed to see her new tail dangling between her legs. All that remained was Monique's first ride in the countryside.... and her Mistress's sulky awaited her.
