Melissa looked on as her captain walked off again. This was becoming a habit with him, they would land on a planet, he'd leave her behind to do god knows what and then return and barely acknowledge her half the time, and when he did pay attention to her he'd stare at her chest, size 32DD a result of her genetically engineered heritage. She'd often strap them down just so men would look at her face one in a while...though more often then not they'd just stare at her ass instead. The bright side was that she got just about anything she ever wanted, other people to do her work, rare and valuable gifts, everything except her captain.

Melissa sighed and went walking down through the local shops. Like every terraformed world, this one had very unique quirks. The climate was sensitive and any significant pollution, even the kind that wouldn't even be considered pollution, like the water vapor produced from a modern hydrogen engine, could cause massive storms. Early on one of this storms sank the city of Atlantis. As a result, traditional cars had been banned and replaced with horses, but fifty years ago a virus had swept through the horse population. Although a few survived, they were rare and since then are often only found in the hands of the rich.

It was what replaced the horses that amused Melissa though. Since shipping horses from other worlds was too expensive for a poor colony that had suffered so much they had made laws that allowed people to be converted into ponygirls and ponyboys. These pony's were recruited from criminals, anyone with a guilty verdict would be sentenced to work as a pony for a period of time. There were also volunteer ponies, people who needed money could sell themselves into the pony workforce. Those who volunteered often had more control over what they did and didn't do as far as ponies go, and after serving for however long their contracts stipulated they would be released with a considerable payment.

The resistant ponies were given injections of nanobots, microscopic robots, that would give what felt like shocks to override their voluntary muscle controls until they learned to behave. It wasn't a perfect system though. Black market trainers would often volunteer targets specified by a client, agency's who rented out real volunteers would often try to pull a fast one, essentially forcing them to be ponyboys or ponygirls for however long they were deemed useful.

The dress of these ponies ranged from practical to erotic as when they made the sla...indentured servants laws, they failed to realize that the decency and nudity laws didn't apply to them and no one had ever bothered to go back to correct this...mistake. Eventually the colony's supreme court allowed ponies to be dressed in whatever manor their owners saw fit.

Melissa sighed, and part of her admitted the idea of having someone else take care of you, feed you, and actually pay attention to you appealed to her. She shook her head of the silly notion though as she sat down in a nearby outdoor cafe and pulled out her private journal. She wrote some observations and some of her fantasies down as she drank some of the local coffee, not realizing that someone was looking over her shoulder.

Several hours later she spotted her captain flirting with some blonde bimbo. She swore under her breath because he had always told her that he was busy with "captain's business" and couldn't be distracted by her, which is why she was always left behind. "I guess captain's business includes molesting women other then me," she said to no one in particular.

She followed him, hiding in the shadows of the alleyways until she saw him go up into a rundown apartment building. She stood there, planning to ambush him when he came out. Eventually it started raining, she snuck inside and stood on the stairways to get out of the storm. Silently she wondered how much it would suck to be outside in some of those pony outfits, being forced to run around in this, with only their burning muscles to keep some of them warm.

Melissa must have dozed off at some point, because she was woken up by a rather...unscrupulous man. He was almost attractive except for a salesman-like quality that he had. He spoke first, "I've noticed the way you've been looking at that man for some time now. May I ask why you appear to be stalking him?"

She shrugged in response, the man grinning. "I suspect that you have feelings for him, that you want him to notice you like he noticed that woman he was with, and for him to take care of you, and use you."

Melissa nodded cautiously. "What's it to you?"

"Well, not much. I was merely going to offer you a chance to obtain your dreams, without any money from you even. Now now, put that raised eyebrow right back down. My little scam here will involve someone else paying me, with you getting everything you wanted by merely playing as the bait." The main gave her a toothy grin. "Now all you need to do is sign this contract," he pulled out a piece of flexi-paper, a small simple computer that was as thin as a piece of paper and could hold small documents."All I need is a scan of your thumbprint"

"Let me see that first," said Melissa. She grabbed the flexi, her thumb pressing in just the right spot for it to register and the device announced "contract signed". Melissa went wide-eyed as even she knew better then to sign something without reading it. "Wait! I didn't..." She didn't even finish her sentence as she fell unconscious again, the result of nanobots that had been injected in her while she had slept.

When she woke up again she looked around. It was a spartan room with a basic bed. She looked around, noticing something long and black sticking out in front of her, something too close for her to identify. Giving up on identifying the oddity she started getting up. That was when she noticed the first change to her. She looked at her hands, only they weren't her hands, they were hooves! Hoof-gloves, like what many of the ponygirls outside had been wearing.

Melissa had a sinking feeling as she dared to look at her feet. Hoof-boots, forcing her to walk on her toes while making the clop-clop sound like she was a horse as she walked around. It then dawned on her just what the black thing sticking out was. It was the nose of a pony-mask/hood. She reached up with her gloved hands, trying to feel for some sort of release mechanism, but she could find anything...not even a zipper on the hood. The she started looking closer at the gloves. After looking closely she realized there were no ties, no zippers, nothing except what she guessed was a bonding agent. She realized she was wearing the same outfit they made the life-sentence ponygirls wear. The kind that were fused to the wearer by nanobots, so they would be ponies forever, no matter what they did to try and escape it.

Melissa hung her head and tried to cry, the nanobots stopping her from even having that luxury. When she tried to yell out, the nanobots made her whinny instead. After what felt like an hour, she gave up on escaping. Even the doorknob was taunting her. It was round and metal so she couldn't turn it with her hooves. She wondered if it was even locked, or left unlocked just to torment her.

After some time the door started opening. The nanobots forced her to stand up at attention, like a well-trained ponygirl. She blushed heavily as she saw her captain among those coming in. "At last," she thought, "he's here to rescue me! I just wish this wasn't how he saw me naked for the first time. Well...almost naked." She reminded herself that she was wearing the gloves, boots, and hood after all.

The thrill of being rescued quickly faded as she saw her captain sign a contract...the same contract she had been tricked into signing. She clenched her hands in anger as she realized he wasn't rescuing her, he was buying her! She tried to signal to him, or actually do anything to get his attention, but was held in place by the nanobots.

The salesman grinned, "you'll find this...model meets to your exact specifications. I'm sure you'll be satisfied with her. She signed on for a life-time contract so you won't have to worry about returning her. And here, as a bonus I'll give you this. It tells you how much she's resisting the nanobots, so you'll be able to tell just how much she's actually willing to do herself...if you catch my drift."

The captain nodded, "thank you. I'm impressed at just how fast you got my custom order done." He lightly caressed her naked skin, Melissa's heart pounded faster. Even though she was being forced to hold still and be molested against her will, there was a part of her that found him touching her like that to be exciting regardless. She blushed at that though, embarrassed that she could feel anything but anger and frustration at the moment.

The pleasure was quickly swept away as he added a pair of nipple clamps to her nipples, making her wince in pain as she was led by the attached chains out to a cart in front of the facility she had been in, a facility that she noticed, looked like a perfectly legitimate pony-agency. She blushed heavily, wishing she could die from humiliation as she realized everyone could see her virtually naked body, the only relief was that none of them knew here true identity with the mask on.

The rain had stopped some time ago, she noted, as she was hooked up to the two-person cart...or was it a buggy she wondered to herself. Each arm was attached to a pole from the cart. If she could she would've dropped the weight as two people got in. Confused by the additional passenger she looked back and saw that the skank the captain had been with earlier was riding along. Melissa fumed at the thought that now not only was she naked, in public, being forced to do menial work, but now she had to do that work for the captain's whore? If she hadn't been injected with nanobots and hooked up to the cart, she swore she would beat him to death with her hooves.

Her thoughts were interrupted by a loud SMACK as a crop hit her bare bottom. The nanobots forced her to walk forward before she even thought about what she was supposed to do. She was forced to run with the extra weight all the way back to the ship, blushing the whole way as her breasts bounced around, their size attracting attention from some of the young men she passed by. Eventually they reached the ship, her muscles aching for the first time since high-school gym class.

Melissa was unhooked and led inside and was forced to follow the captain and his skank around. She blushed as she passed by the various crewman she had known for months, she was quite certain the blush was burned in by now. She wondered if she was going to be forced to be in the captain's quarters when he did what he was inevitably going to do with such a slutty broad.

She was quite surprised when he led her into her own quarters, and even more surprised to find that all her possessions had been removed. The only things in it were a bed of hay, a feeding trough, and a screen built into the wall.

The captain grinned and said, "this is your room. It used to belong to this annoying useless girl who followed me everyplace, but I've replaced her with such a pretty ponygirl. Far more useful then she ever was. You'll be fed regularly in here and treated to special shows of my choosing. And maybe later I'll feed you a carrot. But first I leave a parting gift." He pulled out three marble-sized objects.

Melissa recognized them. They were small vibrators that were small enough to be kept inside her pussy but kept powered up by the slightest movement. There were strong, but they weren't strong enough to bring a woman to orgasm. They could be kept inside a woman for days, the captain having occasionally used them to torture prisoners, keeping them sexually aroused until they broke down. She tried to protest as he teased her pussy lips a little before pushing them inside her one at a time, hir pussy eagerly gobbling them up. As one last method of ensuring they stayed put, he had a crewman bring a chastity belt in. He locked it up, preventing from anything from entering...or exiting.

The captain whispered in her ear, "enjoy the show I'll be putting on. I know the rest of the crew will enjoy the one you'll be putting on soon enough." He gestured to a camera that was placed in the corner of her room. "The revenue from the internet videos and the work I'll make you do will pay for your upkeep. With the money you've spent on the crew's account you should pay off your debt in...oh ten years or so. And remember, you're the one who said the contract saying you wanted me to use you. Guess you should've been more specific on the how."

The captain laughed as he exited the room with the skank. The nanobots released control, not that Melissa could really go anywhere or do much other then walk around the room at this point. Melissa was pissed that he had knowingly done this to her, but even angrier that she had let this be down to her. She barely had time to think about it as the screen built into the wall lit up. She went wide eyed as she recognized the captain's quarters and that the captain and the skank were stripping naked in front of her eyes.

This was only the beginning as for the next ten years would be spent in sexually frustrating nights, watching the captain sex up the skank of the week, and in the morning, the belt and vibrator would be removed as she did manual labor, from moving cargo pallets to working her sphincter as crewman used her ass for a cum dumpster, since they weren't allowed to use her pussy. They couldn't let their nightly entertainment have any relief after all. Every night after work they'd hose her off, feed her, then re-belt her with the vibrators before the process started all over again.

When she had a moment to think, her thoughts would often drift back to the day when she was turned into a ponygirl, and how maybe you shouldn't be careful what you wish for...but rather you should be careful how you wish for it.
