Sarah smiled as she looked down on her best friend and roommate Emily. Sarah had tied Emily to their shared bed and had put a nice purple ball gag into her mouth, before going to work on her smooth pussy with their favorite toy vibrator. Emily had, of course, played her part and squirmed and moaned as her passion built at the tormenting hands and vibrating pulses of the vibrator. Sarah continued her tormenting till Emily had arched her body and squealed behind the gag as she came hard. Now both girls were resting on their bed together, Sarah gently stroking her bound roommate's body.
"Well my dear, sweet Emily. It seems like you had a nice blastoff there, and I know you love to blast off, just like you like to make me blast off when we change our roles. But while you were recovering, I had a look on your computer, and saw you had a deep passion for ponygirls."
Sarah watched as Emily's eyes opened up a bit wider, but she smiled at her roommate, and tickled her pussy as she continued.
"Well, I love the thought of ponygirls too, my sweet Emily. But you know, we both can't be ponies at the same time, unless we include someone new into our games. But that doesn't mean we can't go looking for the perfect tack, now does it?"
Sarah smiled, as she saw the relief in her lover's eyes, and she could feel the heat from her pussy and the passion in her eyes, as Emily thought of their shopping trips. Sarah smiled, seeing the look of excitement in her friend's eyes, and knew they were going to have fun tomorrow.
Sarah and Emily went to sleep for a few hours that night, and woke up the following morning at about 9 am. Sarah untied Emily and both girls smiled as they climbed into the shower together, each taking turns scrubbing the other down, and shaving their bodies smooth. The girls giggled as they dressed, each picking out a skirt, crop top tee, and sandals. They put their hair into a ponytail, and each made sure their purses had their credit cards and their papers, before leaving their shared apartment.
It wasn't uncommon for female roommates to be stopped by the security patrols to make sure they had their freedom papers, which were required after the central government fell to the state militias after some disastrous policies led to an almost 80% hike in taxes. The end result in the aftermath of the revolution was that states could impose their own laws, and many made it a requirement for unmarried females over the age of 18 to carry their freedom papers with them. Of course, women's groups had protested, but once the laws went on the books, women without papers soon found that they were being led off in chains, and sold on the block to anyone who wanted their own personal slaves.
Sarah and Emily, like all the younger girls who had been born after the revolution, had simply learned to live with the requirement, and in a sense, they found it to be exciting to know that they could simply forget their papers, and find themselves bound and gagged and led off to the slave auction. Many girls found the thought thrilling, and some had gone so far as to make their lovers hold their papers. Sarah and Emily had shared their papers now for a year, and both girls tingled at the thought that the other could speak a word, and could doom her friend to the life of a slave, just like that.
As the girls drove to the pet store, they thought of the problem of how to be ponygirls, and still maintain their freedom. They knew that asking an unknown person to be their trainer was taking a huge risk, and yet they both wanted to be in tack together as well. They decided to table their thoughts, as they came to the pet store, and their pussies began to juice as they beheld the sights before them.
The pet store wasn't quite what they had been before the revolution. Now, out front, girls could be seen squirming in pony tack, or tugging on leashes, or sitting in cages, all waiting for someone to either claim them from the store, or buy them for their own use. Sarah and Emily smiled as they admired a girl about their own age, as she wiggled in her pony tack. The girls admired the way the ponygirl was harnessed, and they took time to examine the tack in detail.
Sarah and Emily looked at the ponygirl's hoof boots, and noticed they were laced up tightly. The hoof boots looked like high heeled boots, but the back heel was missing, and the sole instead was shoed with a metal horseshoe. The girls moved up the helpless ponygirl's body with their eyes, looking at the harness. They could see the way the harness supported the girl's breasts, the corset that was built in, and the locks and buckles in the back, rendering her helpless to remove it. The girls also noticed the crotch strap that split the ponygirl's legs, and they could see the stiffness that indicated a thick dildo buried within her pussy. The girls also noticed the thick bushy tail, and smiled as the girl wiggled her ass, sending the tail swishing, to tickle the backs of her legs. The girls continued looking up the ponygirl's body, to her head, where they saw the complex bridle and bit system, and were surprised that the ponygirl had the restrictive pony mask on, which made her head look like a horses head. The girls saw that the bit and bridle was connected to an interior system, but because of rules and etiquette, they didn't dare touch to ponygirl, to see how it was connected. They did see the ownership disk, and took note of the name.
The girls then entered the store, and smiled as they entered their dreams. Within the store was everything needed to turn a girl into a helpless pet slave, to please their owner. From rubber puppy suits to the most complex pony tack, even exotic pets like mermaids could be made within the walls of the store. Sarah and Emily saw the pony section, and made their way over to the rows of equipment, smiling as they got used to the smell of the leather. The girls wandered the aisles, first picking out a cart, and a few items for their shared use. Then came the moment of truth for the girls, the time to buy each other's tack and risk being turned into the other's ponygirl.
A smiling sales lady came up to the two girls, and asked if she could help them with their selections. Sarah smiled, and said they were free girls, but holding each others papers, and that they would be taking turns being each others ponygirl, but that they wanted to have matching tack sets. The sales girl smiled and nodded, and began asking the girls if they wanted the most restrictive, stimulating, or least expensive tack. The girls didn't wait, and said that they wanted the best, and the most restrictive, so that the one in the tack knew she was the pony of the other.
