Author's Note: This story is actually the result of two different ones I had originally. One was some non-kinky science fiction piece about a future where the sun is deadly and people can only move at night. In the other, a young girl builds a special prison to hold her in bondage for a few days. I never could get around to finishing either, so I decided to combine them. Although the first two pages are a bit slow, I think things worked out quite well.

Introduction

Riley moved quickly, using the muscles she had built up over the past six months to force one foot in front of the other. Despite the obscene length of her journey, she still managed to find herself getting tired by the end of each night. As it turns out, when you walk across the United States (or, at least what was left of it), every day winds up being leg day.

The young teenager had never been one for walking, but when the opportunity to get far away from her parents for at least a couple years came up, she leapt at it. The stifling nature of her living arrangements had taxed her patience far beyond a reasonable limit, amplifying the normal phase of teenage rebellion tenfold. While her parents were less than thrilled when she told them where she was going, they could recognize the importance of such a task and knew that with young, healthy people in such short supply, their community would shun their family for their selfishness.

The job given to her had seemed much simpler on paper. Riley was to travel with a large, heavily-armed group on an expedition through the remains of what had been the world's greatest nation. As the team progressed, more and more members of the group would break away, following the crumbling highways to the major cities. Once there, the groups would survey the land, testing the viability of starting settlements, recreating civilization as it once was, and most importantly ensuring that the hostile tribes that had taken over the land were dealt with.

Riley was given one of the final cities. Los Angeles, it was called? She couldn't really remember, and it didn't really matter, given that all the old cities more or less looked the same. Besides, there was a good chance the city wouldn't even still be standing; reports had shown that over the years where no civilized humans had inhabited the city, a large series of earthquakes had struck along the San Andreas Fault. With no satellites or expedient means of travelling from New York City to the west coast, nobody could be sure of what fate had befallen the city until someone had seen it with their own eyes.

Of course, there was also a significant chance the city could be completely intact. A report found from before the end of the world had mentioned something about a massive earthquake levelling the city a hundred or so years before. Given the economic importance of the city and the extreme wealth of the country following its conquest of China, Los Angeles was rebuilt ten times as strong. Experts of the day theorized that the new city could withstand an earthquake with a magnitude of over twelve. Alas, the new construction was never truly tested.

At long last, Riley neared the top of the steep hill. According to her charts, the city would be visible once she crested the hill. From there, it would be about half an hour's walk to the heart of the city. The girl cursed herself silently for being so slow that night; due to her laziness, she would not be able to reach her goal: The radio broadcast antennas on the roof of the U.S. Bank Tower. With them, she could radio in to the members of her team still at the last field base they had set up near Reno, informing them of her safe arrival. In order to account for some of the difficulties in travelling, her team had given her a week's window to contact them. If she did not, they would assume the worst about both her and the city, abandoning all hopes of using it as a settlement. Luckily, she still had three nights left to contact them.

By her calculations, she would come painfully short of the tower. About two and four-fifths of a mile, to be exact. While there would be no shortage of shelter during the day, being able to see her destination as she walked through the city would almost be an insult to her. If she hadn't stopped for that bathroom break a couple hours ago, she might have made it that morning.

A sharp increase in the temperature snapped Riley from her thoughts. She looked first at her watch. 5:54 AM. Next, she looked to the sky. Its perfect blackness was ruined only by a couple faint stars, oblivious to the trials the poor girl had gone through to cross the large desert that was now firmly behind her. While sunrise was still about an hour away, there was no good reason to not be inside when the sun peeked over the horizon.

Finally, after a half a year of trudging endlessly through every type of land imaginable, Riley laid eyes on the valley that held the precious city. To say she was speechless was an understatement; even the small fog of her breath that had been her only companion of hers on the long, cold nights had disappeared. Before her stood countless buildings, their few still-intact windows glinting in the light of the full moon that sat behind her. For just a moment she sat, taking in the wonderful view. The heavy bag that had carried all of her equipment found its way carefully to the ground, content with taking a moment off from its work.

Not ten seconds later, Riley was back on her way. Her gloved hands held onto the straps of her backpack, holding it to prevent it from rubbing on her back too hard. Even with her hoodie, long-sleeved shirt, and T-shirt, she had seen some of her friends with backs that looked like they had been rubbed raw. The heavy-duty tennis shoes on her feet made sure that her feet were always comfortable, despite the protests of her long, slender legs. A pair of tight, wool leggings kept her lower body warm, while a pair of tight running shorts sat beneath those, waiting for when things got too hot for the leggings.

Of course, if it weren't for the weather, it hardly mattered whether she wore clothes. There wasn't a soul for fifty miles at least. She could feel her large breasts ache to be free from the sports bra that had contained them for so long. The cold night air was a constant torment to her, as it caused her nipples to become incredibly hard. Each step caused them to rub gently against the tight bra. Really, it was more annoying than anything.

Riley walked along the highway, crossing over countless bridges and finding alternate routes where the road had worn away. A slight misstep just on the outskirts of the city caused her to fall into a large puddle of mud, dirtying her outer clothes. While she long ago had spares, countless other accidents had ruined them. After climbing out of the mud, she carefully took off her hoodie and leggings. A quick once over showed that nothing else was dirty, which was good as being wet and cold would have been the end of her. Though the sky still hadn't shown signs of the deadly sun, Riley knew that it would be warming up even more soon, and she could find extra warm clothes at any of the countless military installations in the city.

The breath of cool air on her upper body caused a twing in her nipples. She cursed to herself silently, toying with her tits in a vain attempt to calm them down. Without the tight material of the leggings, each step caused the material of her loose shorts to rub on her leg. It was distracting, but at the same time years of social norms engrained in her dictated that she continue to wear the shorts.

Suddenly, the watch on Riley's left wrist beeped. An alarm, telling her it was time to find shelter. She looked to the sky, confirming that the sun was indeed rising. The once calm night had taken on a slight pink tinge, indicating the oncoming wrath of the sun. A quick glance around her showed her she had many choices. Several large concrete buildings, mostly intact. To her left, some warehouses a good distance away. To her right, a...?

Riley took a second glance. The building was unusually barren. Seven stories tall, no discernible windows, no real indication of what it was. The side facing her had a large hole in the thick concrete wall, but aside from that the building was in near-perfect condition. It was also much closer than any other buildings, which was really all that mattered.

Her decision made, Riley set off towards the building, looking forward to a good morning's rest.


Chapter 1

Riley crawled through the hole in the side of the building, occasionally snagging her long brown hair on an errant piece of rebar or jagged concrete. Her ass thrust in the air behind her, wiggling as her legs moved. The shorts clung to her body, faintly outlining a pair of lips. Her pert breasts dangled between her arms, bumping back and forth as she made her way through the hole. The backpack strapped tightly to her chest emphasized them, pushing them out even more.

Ten feet, fifteen feet, twenty... Riley mentally estimated how far she had crawled. What building on Earth would need such a large outer wall? At the very least, she would not have to worry about being disturbed as she slept.

A few moments later and there was suddenly standing room. She stood, brushing the dust from her crawl off of her slender, toned legs. Reaching into her bag, she pulled out a large flashlight and turned it on. The room she found herself in was nondescript and barren, featuring only a metal bed frame, toilet, and sink. The room was quite small, no more than ten feet by ten feet. An open doorway led into a large, dark room.

Riley exited the room, finding herself in a long, dark hallway. The flashlight revealed the walls lined in heavy steel doors, all sitting open. The next room she looked in was much like the first one, save for the absence of the hole she had crawled in. Riley continued down the hallway, checking each room and keeping a mental count of where she was to ensure that she could find her way out.

Some fifteen rooms later, Riley stumbled on what could only be considered a miracle. A bed! Not just an empty bed frame, but an actual mattress, and even a small blanket! After nearly a month of nothing but her sleeping bag, the sight of a bed nearly brought her to tears. Taking off her bag, she laid it carefully next to the bed. For just a minute she sat on the bed, caressing the covers. They honestly didn't feel that comfortable, but compared to some of the places she had slept, it was a miracle.

She stripped, deciding to make the absolute best use of having a blanket. Riley wanted to feel it on every inch of her delicate, teenaged skin. It had been so long that she had even had an opportunity to sleep in relative security, she had nearly forgotten what it had felt like. To give her even more peace of mind, she decided that she would close the heavy steel door of the small room. She didn't expect to have visitors, but at the same time, better safe than sorry.

She reached into the hallway for the large steel handle, gripping it in her fist. With a heave, she pulled the door towards her, sliding it on its rails until it slammed shut with a resounding clang. What she didn't hear, however, was her watch beeping six o'clock. Just as she settled into the bed, pulling the covers up to her chin, a booming voice over a loudspeaker nearly scared her to death.

"WARNING." The voice screamed. "PRISON CONTAINMENT BREACH DETECTED. ACTIVATING PRISONER NEUTRALIZING SPRAY IN FIVE..."

Wait, what the fuck!? Riley thought to herself.

"FOUR."

Riley jumped out of bed, hastily scrambling for her clothes.

"THREE."

Shirt and shorts on, good enough! She ran for the door.

"TWO."

Riley pushed on the door, but it didn't budge. There was no window to break through, and only a small slot on the door that she could not open. What the hell was going on!?

"ONE."

"No!" Riley screamed and banged on the door as a mist of purple gas filtered in from the air ducts, filling the entire building. Riley held her breath for as long as she could, but eventually she succumbed, falling into a deep, peaceful sleep.

Riley occasionally drifted into consciousness. There were no concrete memories, just small bits of light and a slight pulling feeling on her leg. The entire time, she dreamt to herself a quiet scene of herself sitting next to a roaring fire on the most comfortable chair she had ever seen. In one hand was a small glass of red wine, complimented with a thick book. She, having been born long after such a thing was commonplace (if it ever were), had never experienced such a pleasure before.

The reality, though, was far bleaker. On one side of her face she felt the smooth firmness of a polished concrete floor. Between her torso and the floor, right arm, painfully asleep. She slowly rolled onto her back, freeing her arm and wincing as the blood came rushing back to it. Like she had learned back when training for her mission, she tested each of her limbs to make sure nothing was broken. Everything was a little sore, but nothing too bad.

Riley opened her eyes carefully, allowing them to adjust slowly to the dim light of the tiny room she found herself in. Directly above, a large fluorescent light fixture shone down on her. While the fixture was large, only a single bulb remained, casting a mellow light in the room. She pulled her arm in front of her face, checking for the time on her watch. The cracked screen displayed only a blinking 88:88.

The first thing Riley noticed was that she was no longer in the room she was in. There was no bed, sink, or toilet. There were also two doors, but neither was open or had windows. On one of the walls was a small panel recessed a few inches. Opposite it, what appeared to be a speaker. Beneath the speaker, a large push button.

The second thing Riley noticed was an unusual weight around her neck. Sitting up, she felt carefully around her neck. Somehow, a large steel collar had been fastened around her neck. There was no obvious locking method, but there was a small circular hole on the back. A useless tug proved the collar would not be coming off easily.

The young girl stammered to her feet, still woozy from whatever had knocked her out. Grasping the wall for support, she took note of everything she could. At the very least, she still had her clothes. The collar was a strange addition, but so far not a major concern. As best as she could tell, there was no direct way out of the room. She pushed and pulled on the panel next to her, but it did not budge.

That left the button. Riley walked over to it cautiously, making sure not to fall down. The walk was no more than eight feet, but better to be safe than sorry. Riley looked at the button closely. There were no markings, no warnings, no instructions. No way to know what it did. But what choice did she have? Stay her and starve?

Without giving herself time to talk herself out of it, she slammed her hand onto the button.

A brief alarm sounded from the speaker, followed by a voice. Unlike the voice that had spoken before Riley was knocked out, this one was much more calm, almost soothing.

"Attention prisoner 10038645. In accordance to facility rules, you have been sentenced to an extra month for your participation in an escape attempt. Due your designation by the facility as "dangerous", this additional time will be spent in solitary confinement."

Riley stood still, wondering what the hell was going on.

"This will be added to your total sentence, bringing the minimum length of your incarceration to TWO YEARS, SIX MONTHS, FIFTEEN DAYS."

The last part of the message was spoken by a harsh, computerized voice.

Riley didn't have time to process anything before the calm voice continued.

"Per our policy, our automatic inmate transportation unit has taken you to one of our preparation rooms. Please remove your general population uniform and underwear and place them into the waiting receptacle."

Across the room, the small steel panel slid open. Riley went over to it. The inside was small, large enough for a few items of clothing, but no more. There seemed to be no way out, but she obviously didn't want to go walking around an abandoned building naked. Maybe there was a way to trick the machine?

She carefully took off her T-shirt, revealing her stomach and stained sports bra. Placing it into the receptacle, she waited patiently for something to happen.

Without warning, a strong shock hit her in the back of the neck. Riley fell to the floor, tears forming in her eyes.

"Our systems have detected you have not removed all clothes. Please do so within the next fifteen seconds, or you will be shocked again. Shocks will raise in intensity until they incapacitate you. In this event, a manual facility operator will assist you and an extra period of FIVE DAYS will be added to your sentence in solitary confinement."

Still reeling from the pain, Riley raced to her feet, rushing to strip herself of her bra, shorts, underwear, shoes, and socks. She threw them in the receptacle. Though nobody could possibly have been watching her, she felt completely exposed as her pert breasts and pussy were exposed to the cool air.



Another shock to her neck nearly knocked her out.



The voice repeated its previous message, this time adding "In addition to your clothes, all personal accessories including hair ties must be placed in the receptacle. You have ten seconds comply."



Riley cursed the stupid machine, wondering why it hadn't mentioned accessories before. It was as if it was designed to shock you twice!



Riley reached behind her head, pulling her hair tie free and throwing it into the receptacle. Her long blonde hair fell down to her shoulders, barely covering her upper body. Her now broken watch followed the hair tie.



With a whooshing sound, the steel panel slid closed, sealing her clothes away. She looked around the room awkwardly, waiting for something to happen. The voice spoke again.



"Your cooperation is appreciated. Please proceed into the next room."



One of the doors slid open, revealing a room similar to the one she was already in. As she passed through the door, it slammed shut, sealing itself with a loud clunking noise.



"As a standard practice, all inmates in solitary confinement will be required to wear special devices designed to both allow for more effective punishment and to serve as a deterrent from more lewd inmate behavior. It will be removed following your stay in the solitary confinement wing. Please take your device from the receptacle. You have one minute to secure the device or shocks will be administered."



This room's panel slid open, revealing a strange gleaming metal contraption. It took Riley a second, but soon enough she realized that she recognized the device from dsone of her pre-pre-history courses. It was a chastity belt! Men from the time of stone buildings and handheld weapons had once used them to keep their women faithful while the men had gone out raping and pillaging!



She took the belt out and looked it over, making sure to keep a count in her head of how long she had until she was shocked. The belt looked almost exactly like those of the old days, save for some several-thousand years advancements in comfort... and security. The waist band stood open and waiting. Like the collar, there was no obvious mechanism to unlock it.



The crotch plate was a bit more interesting. It hung from the rear of the belt by a thick steel cable. The cable parted near where the wearer's ass would go, allowing them to relieve themselves in the belt. At the front of the plate where the wearer's pussy would go was a small protrusion. It was no more than a couple of inches, but its intension was very clear. It was undoubtedly connected to the same system that controlled the shocks in Riley's collar. In front of the protrusion was a small mound, no doubt for sending painful electric shocks directly into her clit.



Wasting no time, Riley put her bare legs through the belt and pulled it up to her waist. She tried to pull the two ends of the waist band together, but they just barely didn't meet. Whoever prisoner 10038645 was, her waist was about two inches smaller than Riley's. The belt would be incredibly tight, but Riley knew she could do it with a little force. Using the wall for some leverage, she jammed her hands as tight into her waist as she could. If she wasn't quick, the collar would give her another shock!



A moment later, a click signified the belt was secured. The crushing tightness of the belt forced her to take small breaths as if she were wearing an old-fashioned corset. The crotch plate dangled between her legs, waiting for its turn. Riley knew that the extreme tightness of the belt would cause the plug to be forced further into her than whoever the belt was designed for, but she literally had no coice.



Taking the plate in one hand, she lifted the plate up, directing the plug into her. Riley moaned as it entered her, giving sensation to a place that no human or device ever had. Though it was tight, the crotch plate was far easier to secure than the waist belt. Looking down, she could just barely make out the slotted shield that sealed the lips of her cunt away from any eager hands.



"Your cooperation is appreciated. Please proceed into the next room."



The door next door slid open, and Riley walked through to yet another room. In this room, a short metal pole stuck out from the wall opposite the panel. On its end was a small point, but Riley could not determine its purpose.



"To prevent inmates from potentially harming any facility operators, inmates placed in solitary confinement must wear the uniform found in the receptacle. Please put on the uniform. You have thirty seconds."



The third room's panel slid open, revealing what appeared to be a typical orange jumpsuit. Riley took it out, looking it over. On first glance, it did not seem out of the ordinary, though it did not seem to be made out of the typical heavy cotton material. Rather, it had a strange stretchiness to it. Probably some way to make them one-size-fits-all, Riley thought to herself.



Riley worked the garment onto her, pulling her legs through the stretchy material. Pulling her arms into the sleeves, the girl couldn't help but notice how tight the material was; it both clearly showed off the outlines of her new chastity belt and clung so tightly to her skin that there was no way any inmate would be able to hide any contraband under it.



The zipper was also in the back. Riley struggled with it, but eventually managed to get it up, pulling the tight material even tighter across her torso. Once the zipper was up, she looked down at her now mostly-orange body. Only five things broke the monotony of the orange uniform: Her two hands, her two feet, and the shining metal of the crotch plate of the chastity belt. The uniform was crotchless. For whatever reason, Riley could not figure out. An easy way to visually inspect whether an inmate had escaped from their chastity belt? Most likely.



Riley pulled the zipper to the top, pulling the collar of it over her metal collar.



"Thanks to advancements in clothing technology, the solitary confinement uniforms are designed to be worn 24/7 for the duration of your sentence. The facility's high pressure washing systems are capable of washing both you and the uniform concurrently. To secure the uniform, please place the back of your next up to the device attached to the wall opposite the panel."



Riley walked to the pole, grunting as she felt the plug inside her move around. Turning around, she backed up to the strange pipe, careful not to stumble backwards into it. As soon as the device made contact with her jumpsuit's zipper, it made a whirring noise. Riley felt for the zip pull, only to find it replaced by a small cylinder. Somehow, the device had sealed the zipper beneath the cylinder., sealing Riley into the jumpsuit.



"Your cooperation is appreciated. Please proceed into the next room."



Again, the door slid open. A harsh grating noise accompanied it, causing it to stop short. There was maybe half of a foot between the door and the wall. It seems that despite the prison seeming in good condition, its age was beginning to show.



Riley rushed to the door, seeing if she could fit through. She might have been small, but she wasn't that small.



There was no way to get through. Riley clawed at the door, but its thick steel construction made it heavy. No amount of her pushing could get it to budge.



A shock from the collar sent her to the floor, paralyzing her for a few seconds.



"Please proceed to the next room. You have five seconds."



The calm voice made no acknowledgement of the dire predicament Riley found herself in. Finding a sudden burst of strength, Riley pushed the door with all her strength.



It still didn't move. The collar shocked her again, causing her to scream in pain and fear. Tears started to stream down her face as she fought with the door, praying that by some twist of fate it would open. All the while the plug inside her pussy teased her, not enough to be a hindrance, but enough to frustrate the poor girl.

"Please proceed to the next room. Failure to comply will result in the behavior control device in your plug being activated."



Riley screamed, begging the computer to have mercy as if it had a choice. She pushed weakly at the door, crying loudly.



It seemed that whatever fate had imprisoner her in the building had decided to take pity. With a loud scrape, the door budged a few more inches. Just enough for Riley to crawl through. She laid on the floor for a moment, recuperating from the onslaught the damned collar had given her. The voice on the speaker, however, did not give her long.



"System error. Inmate, please close the door manually. Failure to do so will result in prisoner neutralizing spray being activated and an automatic doubling of your sentence in solitary confinement."



The loud, angry voice from before Riley had been knocked unconscious returned.



"FIVE."



Fuck! Fucking fuck! Riley scrambled to her feet and threw herself at the damned door.



"FOUR."



The door creaked, closing ever so slowly.



"THREE."



Beads of sweat began to form on Riley's forehead.



"TWO."



Oh god, please!



"ONE."



The door met the wall with little fanfare. Riley sat leaning against it, listening as the mechanism inside the door latched itself. To her, it was the most glorious sound she had ever heard.



"Your cooperation is appreciated."



The calm voice sounded as if it were mocking Riley, though it had not changed its tone.



"In accordance with facility regulations, all inmates in solitary confinement are required to be shackled at all times. Please take your shackles from the receptacle and apply them appropriately. You have thirty seconds."



The room's steel panel slid open, revealing a pile of steel cuffs and chains. Riley walked to the receptacle, growing tired of her ever-increasing uniform.



All of the metal was quite heavy. The cuffs were not the typical size or shape used in the law enforcement of the previous era. If anything, they resembled the thick shackles that slaves of the colonial era wore. Heavy chain ran between the pair of ankle cuffs and wrist cuffs. Another chain connected the wrist and ankle cuffs to each other. Riley estimated that whoever wore them would not be able to lift their hands very far above their waist or take normal-length strides. How would she ever wear them for... how long did the computer say? A month? She hadn't gotten extra time, right?

Each cuff sat open, waiting for whatever limb to be placed in. Removing them from the receptacle, they fell to the floor. There was no mistaking it, the chains were HEAVY. A strong woman would have even had trouble with them, and Riley did not consider herself very strong.

Fearful of upsetting the authoritarian system now imprisoning her, Riley sat on the floor and began fastening the ankle cuffs to herself. One they had both clicked shut, she picked up the wrist cuffs and closed those. Movement was difficult, but possible. She haphazardly climbed to her feet, trying to quickly readjust her balance for the new weight.

"Thank you for your cooperation. You have now completed all preparations. When the door opens, please follow the flashing lights to your cell. Any deviations from the path will result in a full-powered shock and automatic doubling of your sentence in solitary confinement. As of this moment, your chastity belt has been activated and will also shock you. Please proceed quickly to your cell."

The last door slid open, revealing a bright white hallway. The walls and doors were all covered in some sort of cushioning, giving the entire area a padded-cell type of feeling. On the floor, small lights recessed behind grates began blinking, leading Riley to the far end of the hall. A door sat open, waiting for its new prisoner to enter. Having no choice, Riley did so, feeling her stomach sink as the door automatically locked her in.

Her cell was decorated much like the hallway. The floor, walls, and ceiling were all covered in the padded material. There was no bed. A small, barren toilet with a sink where the tank would be decorated the corner. Even it seemed padded. The door had no window. Had it not been for the fact that Riley had just entered the room, she would not have been able to tell where the door even was, as padding covered the inside of the door.

Her room was a small cube, no larger than a bathroom. There was standing room, but Riley would have only barely been able to lay straight on the floor. She also assumed that the floor doubled as her bed; the padding was not uncomfortable, but it was a step down from the bed she had almost gotten to use earlier.

Though she had been unconscious for some extended period of time, Riley found herself exhausted. Laying down on the floor, she curled up into a ball, adjusting her new chains to find a comfortable place for them. There were none. Soon enough Riley gave up, crying quietly as she tried to fall asleep.


Chapter 2

The new prisoner did not sleep well. Or long, for that matter. Just as Riley felt she was drifting off to a peaceful sleep, the calm voice returned her to a fully awake state.

"Attention prisoner 10038645, it is now time for your allowed daily exercise of one hour. Please exit your cell and follow the flashing lights."

The door to Riley's cell opened, and the flashing lights on the floor directed her down the hall to her left. Her leg chains jangled as she walked, constantly reminding her of just how much trouble she was in. The plug in her chastity belt was not unbearable, but it too was hard to forget. Each step caused it to move, fucking her ever so slightly. The small mound for electrocuting her clit was also an annoyance, rubbing just enough to make her legs slightly weak.

The lights on the floor led Riley through a series of small hallways. Every door she passed was locked, save for the ones the lights guided her through. There were no indications for any sort of exit, way out, or anything. Riley knew from seeing the building before she entered it that there were almost no windows, and more and more the hole she had used to enter the building seemed to have just been a fluke; the entire building seemed remarkably intact. Only a few flickering lights and some chipping paint indicated the building was anywhere near its true age.

Riley arrived at a small room, no larger than a coat closet. The room was barren, save for a door opposite the one she was standing in and a small light fixture overhead. Beneath her, the lights pointed at it, insisting she go in. Afraid that her collar and belt would get mad at her, she did so. The door automatically locked behind her, sealing her into the closet.

"In accordance with facility policies, all solitary confinement inmates are to receive half of an hour of supervised exercise time. So that all inmates remain in good physical condition, your restraints have been outfitted with various devices that will measure your physical activity. Should you not meet the activity requirements, ONE DAY will be added on to your sentence. In addition, any contact with the fence will result in serious shock being administered."

The voice clicked off.

Fence? Riley thought to herself. But that meant... she would be outside!? No!

Riley started screaming, banging on the door to be let back into the facility. If she were released into the yard and it were daytime, that would mean an incredibly painful, albeit fast, end. Years of stories and seeing it happen in person had engrained it into her that the sun is death.

A shock from the plug in her pussy sent her falling to the floor, breathing heavily as she reeled from the pain.

"Maximum noise limit reached."

Riley screamed profanities in her head, cursing whoever had designed the system she was now forced into. She crawled as far away from the door leading into the yard as she could. If it were daytime, just maybe she could avoid serious injury by staying in the small room. She would not be able to exercise, but at the very least she wouldn't die. Riley thought it was a fair trade-off.

Riley listened with great fear as the gears in the door whirred. A click indicated that the locking mechanism was deactivated and the door would now slide open. Riley closed her eyes, terrified of seeing the burning daylight. At last, the door slid open.

Nothing happened. Riley sat for a moment, holding her legs to her chest with her eyes clenched shut. She fearfully opened one eye a fraction of an inch, looking for any sign of light.

The door to the yard sat fully open, waiting for Riley to pass through. Beyond it sat the beautiful serenity of a calm, cool night. Far above, the glint of thousands of stars shone, revealing themselves to a human for the first time since long before the light pollution of Los Angeles had rendered them invisible.

Night! Glorious night!

Riley jumped to her feet, eager to feel the embrace of fresh air on her skin. The yard was not large, but it hardly mattered. There was enough room for Riley to walk around. Two of the walls of the yard were the walls of the building, while the other two consisted of a fence nearly twenty feet tall. Riley walked to the fence, careful not to touch it.

Beyond the fence sat the same ruins she had seen just the previous night from the top of the hill. The moon sat beyond them this time, creating looming back towers against the brightly lit sky. From her position, Riley could just barely make out the outline of the U.S. Bank Tower.

Shit, the tower! Riley was suddenly reminded of her goal. She only had a few days to reach the tower and make contact with her team! But how could she ever break free from the prison? Beyond that, what had even happened to her equipment? She had it before she was knocked unconscious, but it had somehow not found its way with her to the room where she had forfeited her clothes. What had happened? The only way she could see that she lost her bag was that whatever device had taken her to the room had also taken the bag, considering it to be contraband.

Riley added finding her equipment to her ever-growing list of things to do. It was all starting to get overwhelming. Not only did she have to find a way out of the prison, she had to find her equipment, find a way to get out of the chastity belt and cuffs, and finally find a way to get to the top of the bank.

To add to that, she had also just assumed that it was the day after she had first entered the prison. With no timekeeping device of any kind, she couldn't be sure of anything, only that it was currently the start of a new night. What if she had been unconscious for days, and the deadline for reaching her team had already passed?

The consequences of such a thing suddenly hit her. If she did not make it to the tower, her team would not be notified that the city was inhabitable. If her team was not notified, they would never come to the city. If they never came to the city, they would never be able to find her. There was no way to win. To get her group to the city, she needed to escape. Of course, escaping would mean that she would not need her group to help her escape. But she could not escape by herself, of that she was sure.

How long could she live like this? As of yet, there had been no indication of food or water being available. Given the prison was so old, the likelihood of any food in the building still being edible was doubtful. The water could have been poisoned by hundreds of years of pipes corroding, letting their dangerous materials infiltrate the water.

But the building had electricity, somehow. How? Riley looked around the yard for any sort of clue. Far above her, a large bundle of powerlines came from the building. She followed them with her eyes as far as she could. It wasn't far enough, though. They disappeared into the night, blending into the blackness.

Riley thought back through everything she had learned about the city. Founded in 1781, largest city in the country a few centuries later, abandoned before the wars, now empty. At its height, the city had approximately twenty billion people. How could someone get enough electricity for all those people? She stood there silently, listening to the quiet world around her. Far away, the gentle tide of the ocean was barely audible.

Of course! The ocean! Once the population had gotten large enough, politicians had to start looking into alternate sources of energy to keep up with the demand. With the large California coast nearby, their first choice was to go with tidal power! There were probably dozens of such plants littered along the coast, powering the whole city!

"Attention prisoner 10038645, your exercise time is half over. Currently, you have not met your exercise requirements."

Sighing, Riley set about trying to fulfill the computer's nebulous idea of "exercise". How would she even know when she had met the goal? Would the computer voice from the speaker tell her? She didn't know.

Fifteen minutes later, the door back inside the prison opened. Riley walked inside as quickly as the heavy chains allowed. Once inside, the door slid shut, sealing her inside.

"Attention prisoner 10038645, you have not met your exercise requirements for today. ONE DAY has been added onto your sentence, bringing your total sentence to TWO YEARS, SIX MONTHS, SIXTEEN DAYS. Please follow the lights to return to your cell."

The other door opened, and Riley returned to her cell.

"Lunch will be served in two hours," the speaker said.

Lunch? Riley hadn't had time to think about eating, but now noticed she was starving. When was the last time she ate? It had been at least a day, probably more. Beyond that, what was there to eat? There was no guarantee anything in the prison's food reserves was still safe.

She thought back to when she was younger, eating with her classmates in the school cafeteria. They had always joked that the food they were eating was at least better than prison food, despite not actually knowing what prison food tasted like. She shuddered, remembering just how much room for improvement the school cafeteria had. What could possibly be worse?

Making use of her free time, Riley decided to begin exploring her cell and restraints, trying to find a way to get out of them. The girl sat on the floor, putting her back into the corner opposite the toilet. She moved one of her wrist cuffs up to her face, looking it over carefully.

The cuff was a smooth band, broken only by small lines where the hinge was and where the two halves locked together. They were two inches wide, and at least half an inch thick. On the edge of the cuff facing Riley's wrist was a small circular hole, presumably for a key. A small ring was riveted to the cuff, filled with the chain that kept her limbs locked together. The other wrist cuff and the ankle cuffs were all the same. The chains joining the cuffs did not to be particularly heavy duty. Of course, it was still stronger and heavier than it needed to be to contain Riley's delicate form.

The thick steel collar around her seemed equally as secure. It shared the same basic features of the collar, save for slight bumps in the back of the neck that Riley assumed were what administered the electric shocks. There was not enough room to stick a finger between her neck and the collar, but she could reach what felt like some sort of smooth coating on the inside. Most likely, it was to prevent chafing from having pieces of metal rubbing constantly on the skin.

Next was Riley's jumpsuit. It was tight but incredibly stretchy and flexible, showing off every curve of Riley's body like a spandex catsuit would. The thing was also damned near indestructible. No amount of pulling would loosen the cylinder locking the zipper closed, and even Riley's sharp fingernails did nothing to damage the material.

With the jumpsuit on, the only part of the chastity belt that was visible was the slotted shield of the crotch plate. The belt did not have a large bulge where the waistband joined in the front that was typical of older belts. Like the cuffs, the locking mechanism had been integrated seamlessly into the device. There was also no way to remove the crotch plate alone, the whole belt would have to be taken off.

The cell seemed equally inescapable. The room's sole piece of furniture, the toilet, was made out of a soft rubbery material. There were no visible screws, bolts, or anything that seemed to attach it to the floor. There was no hope of being able to use it as a sort-of battering ram to try and break the cell door open.

Only once in her training had Riley heard anything about ancient prisons. Her memory wasn't the greatest, but she remembered hearing something about the advent of affordable automation systems for large swathes of previously human-intensive jobs. Major industries soon became almost completely free of human interference. Naturally, a job as dangerous as prison guard was the first to be automated.

It was very unlikely that any person was controlling Riley. For instance, while her collar had been installed automatically, creating a system that applied the chains, uniform, and chastity belt would have been four times as expensive. So, through the use of a deterrent mechanism in the collar, the prison system could use the inmate themselves to apply everything else. In case of noncompliance, shocks could be administered, or, at worst, knockout gas followed by a "manual employee" (as they called them in the day) being dispatched to apply the restraints to the unconscious prisoner.

Overall, a brilliant system back when it was first designed. Now, however, the cold untiring hand of a computer program doing exactly what it was designed to do was a bit scary. There was no sort of accountability for the system. If it decided to add enough chains that it wanted to add so many chains that Riley couldn't move, it could. Riley could refuse, but then she would just be shocked until she complied.

A method of last resort would be to let the system shock her into unconsciousness. From there, one of three things would happen.

A manual employee would be sent to make her comply, but since every manual employee had died long ago nobody would actually be sent. The system would them assume that the task has been properly completed, and the program would continue as intended. This probably wouldn't do anything, save for waste a day that could be spent trying to find another way out of the prison.

The second possibility was that the system would drag her to a special room where an employee could interact with her. It was very likely that the system would keep her in the room until an employee was able to input a command for the system to continue. From there, either a door would open and allow her to leave under her own power or she would be knocked out and taken automatically back to her cell. Since there were no employees to tell the system to keep going, she would stay locked in the room until she starved or die of thirst.

The third situation would play out much like the second, except for Riley imagined a shining golden door that led straight out the front of the prison and gave her keys to all of her restraints and belt.

So, in reality, two options, none of which would help her escape and both of which would cause her to get shocked incredibly painfully in both her neck and pussy.

So, in reality, no options.

Riley sat in the corner, holding her head in her hands. There really wasn't a way out, was there? There had to be. But where was it? Obviously, the hole she had come in would also work going the other way, but as of right now there was no way to get to it. Whatever way out she found, she would need to find it fast so she could contact her team.

Two hours later, the speaker interrupted Riley's thoughts. During that time, she had not managed to come up with an escape plan.

"Attention prisoner 10038645, it is now time for lunch. Please take your feeding device from the receptacle and place it in your mouth. When the device is comfortable, please secure the device behind your head. You have sixty seconds."

Across the room next to the toilet, a panel of padded wall slid out like a refrigerator door. Riley stood, struggling to pick up the chains with her.

Walking over, she found a strange device in the drawer. It appeared to be a black plastic tube connected at one end to a steel band. The tube was long, but only on the end on the inside of the band. On the end outside of the tube outside the band was what looked like some kind of device to connect the tube to another tube. The tube was hollow. If Riley didn't know any better, she would have said that the whole thing had a sort of phallic quality to it.

Riley carefully put it up to her face, opening her mouth hesitantly. Though the tube might not have appeared that large, she would have to open her jaw nearly all the way for it to go in. Pushing gently, she fed the device down her throat. It was difficult, but she finally reached the end just as part inside her began to tickle the end of her throat.

The hole in the device was not sufficiently sized for breathing, so Riley switched to her nose. Between the tube and the chastity belt, getting enough air into her lungs was a challenge. She could only hope that lunch did not take long. She pushed the two ends of the metal band together, hearing the all-too-familiar click of a lock. She tried to work her jaw into a comfortable position, but could not find one. Every movement irritated the back of her throat, causing her to gag a little.

"Thank you for your compliance. Please connect the feeding device to the provided delivery system."

Above her, one of the padded ceiling panels slid open, allowing a long clear piece of plastic tubing to drop down to shoulder height in front of Riley. The new piece of tube had a device that matched the one on the outside of the piece in Riley's mouth. Riley connected them together, creating a single pipe from the ceiling to the back of her throat.

"Thank you for your compliance. Feeding will now commence."

Riley watched in horror as the clear plastic tube began to fill with a foul-looking brown goop moving quickly towards her mouth. With the tube forcing her mouth open and her tongue down, there was no way she could stop it. Before it had even reached her mouth, she began to retch, fearing the worst taste.

The goop was terrible. Not as if it was rotten, but rather just like bad, mass-produced food designed to be as cheap as possible and deliver the minimum required nutrients regardless of whether it was actually enjoyable to eat. Its texture and consistency was similar to that of chunky diarrhea, though its taste was closer to instant mashed potatoes mixed with... blandness. Riley barely had time to taste it, though, as the tube locked in her mouth forced it directly down her throat.

Suddenly, Riley felt a slight stirring in her pussy. The protrusion filling it had begun to vibrate ever so lightly, giving her a pleasure that her virgin cunt had never felt. Soon the awful food had been forgotten, her focus shifting entirely to the warm pleasure the belt was giving her. She gyrated her hips slowly, trying to get the most of the sensations.

The plug was too short to really give her much pleasure. But, unless the belt was removed, she would never know what more felt like. Until the belt, nothing had ever explored the depths of her hole. No boy had ever taken an interest in her, and masturbation was not taught and difficult to figure out without any sort of help.

The tube automatically detached, retracting back into the ceiling just before the panel sealed itself. The feeding tube in Riley's mouth automatically unlocked, falling to the floor. Riley's hands shot to the crotch plate of her belt with a newfound resolve to find some way under its crotch plate. There was none, and tears of frustration began to form in Riley's eyes.

"Thank you for your compliance," the damned voice said. Riley swore at it, begging to be released from the belt for just a minute.

"Please return your feeding tube to the receptacle. Dinner will be served in six hours."

Riley picked the device up from the floor, throwing it haphazardly across the room into the drawer. It slid into the wall, disappearing among the rest of the padding.

A shock to her pussy and clit gave her a strange combination of immense pain and arousal.

"Please do not attempt to damage facility property. Another infraction will result in another day being added to your sentence."

Riley lay down on the ground, defeated. What else did she have to do? There was no feasible way out of her imprisonment, she accepted that. Everything was too secure, and there was no way to break free from the computer's will.

Dinner was much like lunch. The drawer opened, the tube dropped from the ceiling, the "food" was forced down her throat, and the chastity belt rewarded Riley for eating the food. This time she took a bit more care putting the device back in the drawer, lest she incur the wrath of the computer.

"Thank you for your compliance. Lights out will be in four hours."

Four hours later, the lights went out.

As Riley was just about to fall asleep, an alarm blared over the intercom. Riley sat up from the floor, dazed at the sudden intrusion of noise.

"WARNING." The voice screamed again. "PRISON CONTAINMENT BREACH DETECTED IN GENERAL POPULATION."

What, again? Riley thought. Wait, could that mean... someone else had come into the prison!? Was she going to be saved?

"SOLITARY CONFINEMENT INMATE, ASSUME PROSTRATE POSITION ON THE FLOOR AND REMAIN STILL. ANY MAJOR MOVEMENT WILL RESULT IN LETHAL SHOCK."

Oh fuck, that thing wasn't playing around anymore!

Riley laid on the ground as instructed, stretching her arms as far as the chains let. A few minutes later, the alarm stopped.

"Thank you for your compliance. The situation has been neutralized and you may return to your previous activities."

New thoughts raced through Riley's mind. Had someone else really come in? Would they be able to free her, or would they wind up doomed to the same fate as her? Not once had she seen any evidence that there was anybody else in the prison, but she had not had any opportunity to run into anyone. Could there be someone else?

Riley fell asleep, dreaming of a handsome prince riding to her rescue.

She was awoken again much later to the light in her cell coming on and the computer voice speaking.

"Good morning prisoner 10038645. The time is now ERROR, and you currently have TWO YEARS, FIVE MONTHS, SIXTEEN DAYS remaining on your sentence. Breakfast will begin in twenty minutes."

Riley sat on the ground, thinking. Why had the timer for her sentence not gone down? It had been a day, right? Surely it should have gone down. Maybe it was just a rounding thing? Maybe tomorrow it would go down, and at the end there would just be an awkward half day left.

Breakfast went much like dinner. Exercise time went much like it did the day before, save for Riley somehow meeting the very unclear requirements of exercise. Lunch and dinner followed, filling the abused girl with the foul mess yet again.

Most curiously, there was yet another incident of a containment breach in the middle of the night. Again, she was commanded to lie on the floor, and again the alarms ended only five minutes after it began. Riley thought back to the first day she had come into the prison. It had been some time after five in the morning. Six AM? Without her watch or a clock, there was only one way to be sure.

Again, the next morning the computer woke her.

"Good morning prisoner 10038645."

Yeah, Riley thought, get on with it.

"The time is now ERROR..."

Real helpful. The blonde listened intently, waiting to hear for the remainder of her sentence.

"...and you currently have TWO YEARS FIVE MONTHS, SIXTEEN DAYS remaining on your sentence. Breakfast will begin in twenty minutes."

Riley stood in the middle of the room, her eyes opened wide. What had the timer said? Sixteen days? Had she somehow misbehaved and gotten an extra day added onto her sentence? There wasn't anything she had done that she could think of...

The third day went the same as the last. At night though, as soon as the lights went out, Riley started counting. Assuming she had thought things through correctly, the daily prison break started at 6:00 AM. This was two hours after lights out, which lasted eight hours. The lights turned on at noon, with breakfast soon after. Exercise time was at 2:00 PM, and eventually lights out was at 4:00.

7197... 7198... 7199... 7200. As if on cue, the alarm started blaring, and Riley assumed the containment breach position. 300 later, and the alarm shut off. Six hours later, the lights turned on and she was told breakfast would be served soon. Again, she was informed her sentence was two years, five months, and sixteen days.

Her worst fear had been confirmed. Somewhere over the course of the prison's abandonment, the computer system had managed to get itself into a loop. Each day, the system would reset, starting over as if the day before had never happened. Riley's arrival was the only variable in a thousand years, and all she had managed to do was add another number to the total prisoner count. The time remaining on her sentence would never go down. The prison would always think it was the same day, and it would never notice or care that it was a new day.

Riley's fifth day was the deadline for contacting her team. Not that it mattered, since she had not seen her equipment since her arrival. Since they were not contacted, they would declare Los Angeles inhabitable. Her team would mourn her loss briefly and move on quickly.

That night in the yard, Riley stared at the U.S. Bank Tower with a new type of despair. The chains on her limbs held tight to her skin, inhibiting her reach and step and reminding her constantly of their presence. The belt clinched her waist, but was forgettable aside from the three times a day it gave her the smallest of hopes of an orgasm. She behaved herself well enough that the collar was never a concern. Each night, the tower taunted her in the distance, reminding her of her failure.

Nobody was coming for her. Not now, not ever.
