The beginning

It was currently late evening in Ponyville. The day had gone by, and just about everypony was in their homes, ready to go to sleep and wait for the next day to arrive. Rainbow Dash would normally be doing the same just like everyone else, but today there was a slight distraction on her mind.. although not so slight anymore. It left her bouncing and fidgeting in her room, but also leaving her in a state of arousement and excitement. In short, her bladder was full, with barely any room left to hold in any more pee.

She was about to lose it. She bounced violently in her room, her holding muscles quivering from over-usage. She was about to wet herself. She had been holding in her pee for almost two days now.. Her bladder was over-filled, fighting violently against her holding muscles to try and force the pee out. She didn't dare let up though. She couldn't lose it-- not now not ever!

She bounced up and down violently in her room, walking back and forth in desperation, currently nude for her own personal enjoyment. Despite the tremendous force being forced on her tired holding muscles, she didn't dare let them go. Her bladder reacted differently, however. It was relentless as it tried to force the pee past her quivering holding muscles.. which so desperately wanted to let go under the pressure.. Rainbow moaned, crossing her legs and squeezing, trying as hard as she could to keep her holding muscles clenched. She couldn't keep this up forever though.. her bladder kept getting fuller.. and her holding muscles kept getting weaker.

She quickly sat down on the bed, fidgeting violently as she did. She pressed her hands against her plush vagina, squeezing it. She couldn't lose it now! Not yet! She tried desperately to keep her quivering holding muscles to stay clenched closed, causing her to pant in a mix of exhaustion and effort.

She lied down on her bed and squirmed, pressing her legs tightly against each other in an attempt to help hold it.. She could barely keep doing this! She continued straining her holding muscles to their limit, determined not to let herself lose it. She didn't want to admit she could wet herself. She wanted to be the boss over her bladder and not let it control her.. So why was she wasting time in her room?

She forced herself to sit back up, moaning as she accidentally put pressure on her bladder. She wasn't going to let her bladder do this to her. She got off the bed, trying desperately to keep her exhausted holding muscles clenched. She walked out of her room, still completely naked, her breasts and her plump pussy being shown in all their glory. She felt a specific feeling of free-ness she didn't feel all that often.. and her full bladder only made the feeling more intense.

Her bladder was relentless to empty however-- spasming violently as it was over-filled. She didn't dare let it empty though. She crossed her legs, clenching her exhausted holding muscles harder, just barely managing to hold it. She had been forcing her holding muscles to go too far for too long. She was over-straining them so much.. her tired, exhausted holding muscles were so weak now... they just wanted to let go and relax.. but Rainbow knew she couldn't let that happen. She knew she had tough holding muscles-- she was going to make them hold up to the task of holding in her pee. If they couldn't do that, then they were useless in her eyes.

She uncrossed her legs and started walking again, looking around. She didn't really want her bladder to get in the way of her daily activities, but what could so do? All that was on her mind was her rapidly over-filling bladder, making it hard to think. She could fly, but that would be too strenuous... but then again she had originally planned on not letting her bladder control what she was going to do anyway, no matter how strenuous it seemed. She tried to reassure herself more that she would be fine by taking a couple deep breaths, before briskly walking over to her front door.

Upon making it to the door she opened her it and stepped outside, closing her door behind her. She felt the cool evening air blow across her bare body, causing her to shiver a tiny bit from the unexpected breeze, although it was nothing she couldn't handle. She also felt slightly nervous, but not because she might wet herself, but because she was naked. It was dark out, but she still felt like anyone could be watching. After several seconds of quick thinking though, she thought up of the daring but exciting plan of flying over the Everfree Forest. She figured no one would ever see her there.

She went to open up her wings, but found they were already open, most likely due to a wing-boner from the arousement of holding in her pee for so long. Speaking of pee.. She suddenly began to feel her bladder spasm, and she knew what type of spasm this was. Average ponies would practically always wet themselves after this. She felt the pee start to go through her urethra, her holding muscles feeling like they were powerless to stop it. If she tried to clench, it would seem like nothing happened.

Most ponies would panic at this point and end up wetting themselves, but she knew how to prevent that from happening. She didn't panic, because she knew her holding muscles can hold it. She felt the pee keep pushing through her urethra with seemingly unstoppable force, but she was not ready to let it come out. She instantly crossed her legs so tightly it hurt, and made a fist, before jamming that fist in her vagina. She then clenched so hard she moaned from pain, straining her holding muscles even more. She then felt the pee; it was right there, and feeling like it was about to come out.

Her eyes widened in pain as the pee tried to force it's way past her holding muscles, which were seemingly screaming out in pain now. She couldn't lose it yet though-- especially not outside! She kept clenching her aching holding muscles as if her life depended on it, not daring to let up. After a few more pain-filled seconds, the urge finally started to surpass, but she couldn't let go just let. She knew if she did a squirt of pee would come out.

She kept clenching for a few more seconds, before her holding muscles starting quivering, but thankfully enough time had already passed. She almost instantly relaxed, her holding muscles nearly completely relaxed now. There wasn't any urge at the moment and the pee didn't feel like it would come out, but she still was careful. If she relaxed them too much the pee would come out anyway. Urge or not-- she was that bursting full.

She had also used her holding muscles to the limit, though, and they were dead-tired. Just clenching them hard once almost seemed equivalent to doing 500 wing-ups. Based off some experience, she knew she'd be alight for awhile now. At least she hoped. With how tired her holding muscles were, she didn't know what would happen.

She quickly tried to think about something else, however, like flying. She started flapping her wings, being very very careful not to put pressure on her bladder. Normally she wouldn't have cared, but she felt that just the smallest pressure on it would cause her to lose it in a massive burst of pee. She started to lift off the ground, before flying over to the Everfree Forest.

On the way there she was met with a couple small urges, most likely due to the activity, but she was able to hold them. She kept flying for a few more minutes, enjoying the nice cool breeze across her plump vag and breasts (Which she didn't feel that often.) Until to her ultimate dismay, she felt another one of those urges.

This time it was harder not to panic. She was in mid-air, and this urge felt powerful. She wanted to land, but there was no-where she could go to land fast enough. Granted she could easily fly to the ground in just a couple seconds, but the effort she would have to put for that speed would ultimately press too hard on her over-filled and over-stretched bladder, and she knew she would lose it then. This meant she had to do it in midair, while flapping her wings. In all honestly, Rainbow didn't think she would be able to do it. But she wasn't going to give up without a fight.

When she thought the time was right, she crossed her legs as tightly as she could, jamming her fist in her vag. She then clenched as hard as she possibly could-- it might've even been the hardest she clenched ever. At least that's what it seemed like. But would it be enough?

It actually took a few seconds for her holding muscles to fully clench. They were sluggish and tired-- they had been pushed nearly to their limit too many times. Maybe, one too many times.. Rainbow can only push them so far... those poor holding muscles...

Eventually the pee reached her holding muscles, and she gasped. She even squealed as she squeezed her eyes closed and clenched her teeth, trying to clench her holding muscles even harder. Too hard.. The pee was literally a split-second from coming out now. She felt it right there-- her holding muscles just barely keeping it back. Any sane pony would've let them let go and let the pee burst out, and it would burst out. It would burst out so hard it'd probably be like a jet, but she wasn't like that. She was going to try as hard as she could, because there was no way she was going down without a fight.

Her holding muscles started to get even more exhausted, but so did her urge. She realized-- she could do this! She panted heavily, sweat completely covering her. She just had to keep clenching.. if the urge kept going away like this, she knew she could do it. Every fiber of her being was pushed to the limit as she kept clenching her poor, abused holding muscles. She felt her bladder kept trying to push out the pee, but she knew she was winning. Until she realized.. she was falling.

She had pushed herself so hard she forgot to keep flapping her wings. She was falling straight for the forest. She instantly went to flap her wings, but that additional movement-- that one additional movement.. was her worst mistake.

She had lost it.

Pee ripped right past her holding muscles, which offered close to no resistance and literally burst out her plump pussy, shooting out like a jet, probably going at least over three yards. She yelped in shock and stopped flapping-- she didn't care if she fell. Holding it was the most important thing in her life at this moment. She tried to clench again, but she quickly dismissed that as useless, as her holding muscles were seemingly in-responsive. There was only one thing left she could do. Something only she could do..

She clenched the outer-folds of her marehood closed, something she had learned to be a rare talent as no other mare seemed to be able to do it.The pee stopped shooting out, briefly pooling in the small area behind her folds. The small space was quickly filled though.. and her bladder noticed this.

She moaned at the strange feeling she was experiencing, which was quite pleasurable, but she had to focus. She quickly started flapping her wings again, barely managing to miss hitting a group of tree branches. She had to lower to the ground otherwise she knew she would lose it. This was her emergency ration, she couldn't keep those sweet folds clenched for too long. She had to get down, and use her holding muscles-- she knew she'd be able to use them much easier once on the ground.

She found it hard to focus on getting down, her over-filling bladder and the effort she was putting out to keep it full made it hard to think about anything else, but it was enough to be maneuverable. Meanwhile, her bladder kept spasming. It squeezed into a cone shape, trying to force the pee out, even harder than before. Her plump, precious folds were straining to keep clenching. They weren't used to this. Rainbow moaned in pain and pleasure as she kept sloppily gliding down, the ground slowly starting to get closer.

It was beginning to become too much though. It was swollen down at her marehood.. the pee kept trying to force it's way out, making it seem even plumper than before. Despite how sexy it must've looked, she couldn't look. Her sweet, folds were almost trembling now.. it was beginning to become too much for them..

She didn't let up however, and kept her holding muscles tightly clenched. She was almost at the ground.. she was so close... she had to keep them clenched-- she was almost too close now. Her bladder spasmed again, trying to force the pee out even harder. Her precious folds were about to break apart... they trembled more, a tiny trickle of pee starting to come out. It was as if the dam was at it's breaking point..

She moaned as she forced her folds to clench harder, managing to stop the trickle. They felt like they were about to just burst apart, the pee trying to force it's way through with almost unbearable force. She squealed as she teared up in both pain and effort, her precious folds bulging out even further. The pee was so close to bursting out... her bladder only kept spasming, making it unbearably worse. She was only on the last shreds of her will-power now, starting to over-strain her plump folds.

A glimmer of hope shined through as she noticed the ground come into view, however. She could do this! She could go further than any mare as ever gone! With new-found determination, she clenched even harder, her sweet folds pressing so tightly against each other.. She knew she could do this.

Every passing second was like pure torture. Her folds so desperately wanted to let go, but she didn't let them let go with all the willpower she had. She was going to make herself do this.. no matter what. The ground kept getting closer and closer... until, to her ultimate horror, her bladder began to spasm again. A violent one.

With the pee already mere milli-seconds from coming out, it didn't take long at all before she felt the effects. She squealed as she felt the pee push against her folds with nearly un-stoppable force, puffing them out even more-- too much... A small trickle of pee started to come out again, Rainbow seemingly powerless to stop it. Her folds were too exhausted... they had been pushed over the limit.

More pee started to trickle out, drips of it going in any direction. It literally looked like a dam was about to break, and it seemed as if she was helpless to stop it. She was pushing her folds so hard they were visibly quivering now, more tears forming in her eyes from the incredible amount of effort she was putting out. Her attention was suddenly brought to reality as she felt her feet sloppily land on the ground. She had finally made it!

A spark of excitement and determination shot through her as she landed, her feet shakily touching down on the ground. Pee kept trickling out through her folds however. If she tried to clench harder, it was as if her sweet folds were unresponsive. They were truly at their limit now, but that didn't matter. She was finally on the ground-- she had lasted long enough!

She took a huge, deep breath, preparing herself for what she was about to do. Before she started, however, she couldn't help but to look at her pussy-- the very thing that had kept her from wetting herself so far. Her eyes widened in shock, and as if in an instant, she suddenly became incredibly aroused. Almost as horny as she had ever been in her whole life. The sight of how plump and swollen it was, the pee trickling out like a loose water spout... the sight seemed to be painted in her mind, as if she would never forget it. She unfortunately couldn't spend any more time looking though-- she felt as if she was going to burst any second.

After taking a few shaky deep breaths, she quickly crossed her legs as tightly as she could, and clenched her holding muscles as hard as possible. Thankfully her holding muscles seemed to of regained some of their energy while they were relaxing, which proved to make it slightly easier to cut off the flow. In the process, however, as her holding muscles clenched, it not only pushed the pee back in her bladder, but also tried to push it out. It instantly became too much for her precious folds, and they burst apart.

The pee that was pooled behind them shot out like a rocket, literally kicking up a small bit of dirt that was on the ground. This was short-lived, though, as the pee inside quickly ran out, only drops dripping off her exhausted folds, the rest being held back in her bladder by her holding muscles.

Her bladder spasmed again in protest, but due to her semi-restored holding muscles, it wasn't too difficult to hold the pee back. After a few seconds her bladder stopped spasming as fiercely, and her violent urge seeming to almost magically fade away, and hopefully not coming back for a reasonably long time. It was only then she realized just how exhausted she was, and she let herself collapse on the ground, panting and being completely covered in sweat.

"Oh... my... Celestia..." She muttered to herself, before starting to smile a tiny bit. She had done it. She had done what no mare had ever done before. She used her sweet pussy folds to hold in her pee, after she had lost it. She couldn't believe how happy she was with herself. From there, she vowed to never let herself pee again. Now of course, as much as she didn't want to admit it, she would eventually. But she quickly dismissed that thought, smiling to herself. She wanted to believe she could hold it forever for now.

Her attention was eventually brought to her lush pussy, and her eyes widened a little in arousement as she looked. Her folds were dead tired and relaxed, laying limply to the sides, exposing the inside of her beautiful pussy. She only stared for a couple seconds, before she came to a rather obvious decision.

She had to masturbate.

A memorable night

The orgasm she experienced from her previous fapping had to of been one of the most intense ones she had felt in a long time. Although it hadn't even been a minute before she climaxed, the incredible aroused state she had already been in had multiplied the pleasure. She lied her head back against a near-by tree, panting and sweating from her previous fun time. She was exhausted, tired, and she wanted to sleep. She felt and saw how full her bladder was, which was bulging a couple inches outwards, but thankfully it wasn't bothering her too much.. yet. She closed her eyes, quickly letting herself drift off into blissful sleep.

She eventually woke up sometime during the night to find her bladder was spasming quite violently. In reflex she pressed her legs together, bringing her hand over to her pussy and squeezing it slightly, managing to hold back the urge that had woke her up. By now her bladder was in a constant dull ache-- a somewhat painful yet pleasurably arousing feeling coming from it. As she looked at her bladder, she found it was bulging out even further than when she had last fallen asleep. Its shear size and volume was something that, in her mind, she just had to hold in. She couldn't help but place her hand on her swollen bladder, gently rubbing it slightly, feeling its

unbelievably full and firm texture.

"Man I don't think it's ever been this full.." She smiled, but her bladder was quick to start protesting. It spasmed, trying to force out the pee that's been trapped inside of it for so long. Her urge to pee had gotten much, much worse while she was asleep. Rainbow only clenched her urinary sphincter in response, moaning lightly as she felt herself continue to keep back the massive flood. She didn't want to sit here for the rest of the night however--her bladder's spasms were only going to get worse and worse as time went by.

Her attention was then brought to her surroundings. She had fallen asleep in the middle of the Everfree Forest! That probably wasn't the best idea ever, but now that she wasn't awake, she couldn't really care less. She would just have to try and avoid doing it again, which was something she wouldn't have to worry about at the moment. Her over-filled bladder would most likely make it impossible to fall asleep again.

She stood up a few seconds later, moaning a bit as she felt her bladder spasm more from the movement. She held her breath and pressed her legs together, fidgeting and bouncing a bit as she struggled to keep her sphincter clenched closed. It was already a miracle she hadn't lost it before she fell asleep, but now her bladder was even fuller than before. She exhaled slowly and shakily as she looked down at her bulging bladder, staring at it in arousal for a few seconds before perking her head back up, looking around. She was obviously lost, but she knew if she ever wanted to get out she could just fly away using her powerful wings. For now, though, she decided to look around. The thought of exploring the forest, with absolutely no clothes on and an over-filled bladder kept her in a constant state of arousal.

Without spending anymore time looking around, she started to walk off in the direction in-front of her. Her gait was brisk and tense, her legs closer together than usual as she made her way through the forest. Her bladder was constantly reminding her how full it was, her urinary sphincter struggling to hold back the massive flood inside of her.

She kept walking, stopping to fidget and cross her legs every so often from her urge, before eventually coming across a small lake. She smiled as she walked up to it, pressing her legs together and squirming a bit as she looked down at it. It was surprisingly clean, some of the light from the moon reflecting off of it through the trees of the forest. Figuring it would be nice to do something else other than just walk, she decided to swim around for a bit.

She placed her foot in the water to test the temperature, her whole body tensing up a little more as she tried to stay still on one leg. The water had a bit of a cold sting to it, but she doubted it was anything that was too cold for her. She was already used to freezing cold weather from her job at the weather factory anyway. She got in position, before jumping towards the middle of the lake, bringing her legs close to her body and wrapping her arms around them. Upon making contact she made a huge splash, her body being submerged in the water.

Big mistake.

The instant her body was submerged in water, her entire, exposed body was overwhelmed with cold-- colder than she had thought it would be. She jolted from the initial shock and pressed her legs hard together in the water, her bladder spasming violently in response to the cold. Getting desperate for air, she quickly resurfaced, taking a large breath of air as she held her arms close to herself.

"Dang that was colder than I thought it would be! Stupid water." She said to no one in particular. She squirmed in place as her bladder continuing being defiant, her urge getting much worse than before due to the cold. She tried to play it off like it was nothing though, ignoring it as best as possible. "That's not gonna stop me from taking a swim though." Taking a deep breath she submerged herself under the water, lightly swimming downwards.

She felt the cold lake water brush smoothly against her completely bare skin as she swam, the light from the moon illuminating the inside of the lake. Her legs were still close together as she kicked them, close enough for them to be rubbing against each other as she swam across the bottom of the lake. She could especially feel the cold water where her bulging bladder was, which was continuing to relentlessly spasm. She kicked her legs faster in an attempt to help herself hold it in, her already exhausted urinary sphincter being strained to keep clenching harder and harder. Figuring she had been under long enough, she began to swim upwards, breaching the surface of the water only a couple seconds later.

Taking a gasp of air, she fidgeted and squirmed, moaning lightly from her fierce urge. Despite being so cold, she couldn't help but feel increasingly turned on by her current situation. Feeling the cold water make contact with her bare pussy didn't help with that, either. As she floated in the water she couldn't help but look down, her badder clearly bulging from beneath the water. She shook back and forth in the water as she stared, her heart beating faster in her chest as her mind kept being flooded with lust. She could also see how erect and hard her nipples were from the cold, only making her feel increasingly horny.

With her bladder's constant spasms taking her out of the mood for swimming, she made her way over to the edge of the lake, briskly climbing out. Upon standing up the ground, she could feel the cold night air blow against her wet body, making her shiver. She rapidly tapped her feet on the ground and squirmed from her ever-growing desperation, looking around. She had completely dismissed getting something to dry herself off with.

"Gosh I'm stupid." She frowned slightly. She figured she might as well fly back home and get a towel to dry herself off with. Opening up her wings, she started to move them back and forth, trying to shake the water off of them. She crossed her legs and moaned a bit as she did so, walking in place from her urge again before starting to take off, flying upwards and eventually past the trees.

Upon making it past the tree-line she pressed her legs together, moaning before suddenly gasping. Her urge to pee was really getting much worse now.. She breathed shakily and squeezed her eyes closed, groaning as she clenched her abused sphincter as hard as she could.

"C'mon I just gotta get back to the house-- it'll get easier once I'm there." Flapping her wings harder, she flew off in the direction of her house, hoping it wouldn't take too much longer.

The entire trip there she was squirming and fidgeting, her over-filling bladder getting closer and closer to forcing its contents out. By the time her house began to come into view, she felt like she was about to lose it.

"Finally!" She quickly flew over to her front-door, letting her feet shakily touch the ground. Nearly instantly after landing she crossed her legs as hard as she could, moaning as she hunched her body over. Her urge was getting too bad now, and she started to wonder if she could even last the next few minutes.

Fidgeting excessively, she hastily opened the front-door to her house, making her way inside before closing the door behind her. She started to fiercely walk back and forth, breathing intensely as she felt only minutes away from possibly losing it.

After walking back and forth for a little longer, she made her way over to her closet, taking a towel and wrapping it around herself. Flying back to her house had dried most of her off already, but she figured she might as well dry the rest of herself off. She continued to walk rapidly and make short steps as she made her way into her bedroom. Sitting down briskly, her bare bottom made contact with the bed, and she moaned as she felt her bladder spasm violently. She pressed her legs together, her feet swiftly patting the ground in desperation as she strenuously kept holding it in. Her urge showed no signs of going away this time..

She quickly started drying herself off with the towel, her movements fast and sloppy from her desperation. It was nearly impossible to keep her legs still, and within only a few seconds she had to bolt upwards and stand up, crossing her legs as hard as she could. Her eyes widened and she groaned loudly as she tried to hold it, trying to cross her legs even more before suddenly walking in place again. She hastily decided that she was dry enough, and threw the towel on her bed, before pressing her legs hard against each other. She couldn't stop fidgeting no matter what she did, and she knew that was a sign that she was approaching her limit.. She may have been able to luck out once, but she couldn't help but doubt she could do it again..

Although hesitant, she eventually and slowly walked out of her room, her legs pressed against each other the whole way. Her eyes came across the front-door, and she thought over whether or not to go back outside. She knew it would be completely crazy-- insane even, considering how bad her urge was right now, but she did tell herself not to ever let her bladder boss her around.. Just the thought of going outside with this bad of an urge turned her on. Even though she knew it probably wasn't going to end very well, she decided to go back outside.

As she walked to the front door, she felt another huge urge strike her bladder. She gasped and bent down, crossing her legs tightly, forcing her holding muscles to clench harder, barely managing to keep it in. They were getting weak fast... she thought twice about going back outside, but she wanted to be the boss over her bladder, and not let it control her.

She opened the door and quickly walked outside, breathing shakily. She literally felt like she was about to lose it right then. Her holding muscles kept quivering, exhausted from all the clenching, and her bladder kept spasming against them non-stop. She could almost already feel her pee push through them, ever so slowly getting further and further down her urethra. She tried to ignore it as much to her ability, though, and began flapping her wings, which were already wide open from a wing-boner. In a couple seconds she started to lift off the ground, before speedily flying off in the direction of the Everfree Forest.

As she was flying, she kept feeling spasm after spasm from her bladder, almost making her lose it a few times since her pee got so close to exiting. This was already getting really bad. She moaned as she pushed her legs together, trying to help herself hold it. She felt her heart beat rise as she began to realize she might not even make it the next couple minutes. She flew faster, wanting to get to the forest as fast as she can.

Within about a minute she arrived, and she flew over it for a couple seconds before landing inside, very close to the entrance, still breathing shakily from the effort. As soon as she landed she crossed her legs as tightly as she could, trying to clench her unwilling holding muscles harder. She managed to keep them closed until the momentary urge went away, and she tried to catch her breath afterwards. She knew the end would be coming in only a matter of minutes. If she forced herself hard enough, maybe another half an hour. After all she kept thinking she would lose it in the next few minutes for awhile now. But she doubted she would last until the morning..

It was then she realized if she actually did hold it until the morning came, she would've made it for three, whole entire days. Her bladder would've been bursting full with over three days worth of pee... that would've been beyond amazing. She sighed knowing that would most likely be impossible, but she was still going to try.

Her bladder spasmed again, each spasm getting more violent as her bladder got fuller and fuller. She bounced and shook her legs as she struggled to hold it in, her holding muscles straining against the pressure. She managed to hold it and sat down on the ground, hoping it would help.

Her legs shook violently as her bladder kept spasming, bringing her legs closely together to try and help. Every second it felt like she was closer to just wetting herself, her holding muscles getting even more exhausted. She couldn't keep clenching them like this.. they had already been pushed to their limit too many times before.. Constantly they had been used, for over two days now.. they couldn't keep doing this.. Everything has it's limits..

Rainbow refused to believe that though. She didn't care if she forced them to clench for months-- she knew they were tough and they could handle it. With the way things were heading, though, she was slowly beginning to doubt she could last much longer. She would've already lost it hours ago if it weren't for her plump marehood. But her bladder wasn't as full then-- this time.. this time it was too full. It had already been stretched further than it could hold.. it couldn't keep stretching like this. It needed to empty now.. Two days was already long enough for it. Her defiant bladder didn't want to stay full for three days.

She moaned again as she quickly stood back up, sitting down not seeming to help that much. Her legs shook and squirmed violently, her holding muscles continuing to quiver. She was nearly clenching them as hard as she could now, constantly. She would've desperately wanted her holding muscles to suddenly somehow be refreshed, but she knew that wouldn't happen.. it was unfortunately only a matter of time now.

She continued bouncing and fidgeting violently for several minutes, using every bit of her willpower and strength to keep her holding muscles clenched tightly closed. She wasn't even focusing on where she was going-- just about all her attention being focused on holding it in. Her gait was slow, and she had her legs pressed hard together the entire time she walked, which was only in small but rapid steps. She wanted to relax but she couldn't-- her bladder was too full and being too relentless for that. Her absolute limit was being reached... for two, whole days now. Two whole days she held strong, and defied all odds. But.. this time might finally lose it. In the middle of the Everfree Forest, no less, still with absolutely nothing covering her.

She knew if she ever lost it she could always clench her plump folds to hold it, but that was more like her emergency ration. She wasn't that used to using them, and they weren't used to holding back so much pressure. Most if not all other mares couldn't even do it in the first place-- once their holding muscles gave up that was it. Which struck Rainbow as a little pathetic, but.. she couldn't complain. If it wasn't for her being able to press her outer-lips together she would've never been able to last this long.

Her bladder's constant spasms were becoming too much, though. She shook her legs violently as she felt a harsh urge hit her. She moaned as she crossed her legs tightly, squeezing her eyes closed as she tried to clench her over-used holding muscles further. The pee stayed right there, pressing against her sphincter for a few seconds, before slowly starting to go away, her exhausted holding muscles starting to quiver more. After a couple seconds she let them relax a little, now panting and sweating from the effort. There was unfortunately nothing she could do to make this any easier..

She looked down at her bladder, her eyes fixated on it's huge bulge. She so badly wanted to keep it full like this.. She wanted it to last forever so, so badly. It was bulging so far out, so full of days worth of pee. She didn't want it to ever empty-- she wanted to feel the sensation of holding it in forever.

Of course forever was probably too much, but at least for right now, she didn't want it to empty no matter what. It was always better to have a full bladder to her. Especially this amazingly full... this was easily the most she had ever held, and most likely much more than her friends can hold. She almost wanted to show it.. or at least keep record of it somehow.

Keep record of it. This thought hit her like a rock. If she lost it, she wouldn't be able to see her bladder was this full again! At least not for a very long time.. she had to take a picture of it. Something to show that she had actually held in this much. Her camera was all the way back at her house though. That would mean she would have to fly all the way back..

She gulped slightly at the thought of that. The last thing she wanted to do was fly again-- she could already feel her pee get closer and closer to exiting every time her bladder spasmed.. At her current stage of desperation right now she felt like she would lose it once she lifted off the ground. She had told herself not to let her bladder control her, though.. She inhaled, feeling nervous; she could just picture herself losing it in mid-air, her pee splattering everywhere onto the ground like a sprinkler.. Her body tensed up just at the thought of it, and she shook her head a bit, trying to get that thought out of her head. She knew she was capable of doing this successfully.

As if to cripple her confidence, however, she felt another urge as her bladder spasmed. It was one of 'those' urges. She tried not to panic, and waited, feeling the pee slowly go through her urethra, her exhausted and abused holding muscles simply lying limply and letting the pee flow through. Before her pee came out, though, she took a deep breath, crossing her legs as quickly and as tightly as she could. She squealed and moaned as she clenched her sphincter as hard as she possibly could, her body jolting slightly from the painful effort. She could even feel her bladder squeezing itself, trying to form a cone shape in an attempt to force its contents through. Rainbow didn't give up though, holding her breath as she tried to keep her over-used sphincter clenched closed.

She kept clenching, her body as still as a statue. She felt her pee continuously pushing against her holding muscles, which were just barely keeping it back. They were so exhausted by this point.. She couldn't keep abusing them forever like this-- she liked to believe they could hold in anything, but even she had her limits, even if she didn't actually believe in them. She puffed out her cheeks as she kept holding her breath, still not daring to move from her position.

After a couple seconds her holding muscles started to quiver from over-usage. Fortunately, at about the same time her urge thankfully started to go away, but she still couldn't let go. She knew if she relaxed too soon a small bit of pee would come out, and she wanted to keep every single drop inside. She moaned, her holding muscles quivering more intently as she tried to force them to stay closed for just a little longer.. She slowly started breathing again as she felt her lungs get desperate for air, until she finally felt her pee get pushed all the way back into her bladder. She almost instantly but slowly relaxed her holding muscles, feeling them relax in throbs as she started panting lightly, even sweating from the intense effort. She had managed to keep all her pee trapped inside her bladder without losing it..

That was just one urge though. It was only going to get worse from there, and she still had to get to her house. She took a couple shaky breaths, trying to focus. She could do this... she could do this.. She still hadn't used her plump folds yet. Not wanting to waste anymore time, since she felt as if another urge could easily overwhelm her, and she began flapping her wings, flying upwards and out of the forest.

Barely seconds after she lifted off the ground, she started feeling several small but violent urges. Her bladder wanted to empty right this instant. Despite so badly wanting to relax, she clenched her holding muscles again, this time in contractions. She couldn't even keep them completely clenched by this point, and she knew she had to hurry. She flew faster, feeling the wind brush across her bare and exposed body. As nice as it felt, and as horny as it made her though, she couldn't focus on that due to her quickly overwhelming urge.

She couldn't keep doing this, though. About halfway through her holding muscles started to relax against her will, and she struggled to keep clenching them to hold back her bladder's urges. They quivered every time an urge came, and she had to force them to clench harder just to keep squirts from happening. Eventually, to her horror, however, she felt another incredibly bad urge start coming.

Her flying almost unconsciously slowed down until she was just hovering in place.Her holding muscles practically completely relaxed now. It was like she couldn't use them. She exhaled shakily as she felt the pee start to go through her urethra.. Gosh it would feel so good to just let go... and let it all out... to relax so blissfully.. She already started to feel her whole body relax as the pee went further down her urethra.. it felt so mind-numbingly good.. To finally empty her over-filled, swollen bladder... filled with so much pee... too much pee...

She gasped as she tried to get rid of those thoughts, her legs kicking slightly in the air before she crossed them as hard as she could. She managed to clench her holding muscles, but the immense amount of pressure she felt from her bladder was almost immediately too much. Her eyes widened and her cheeks puffed out, moaning loudly through her closed mouth. The amount of pain, pleasure and pressure was unbelievable. She moaned louder and started to tip upside-down, doing everything possible to cross her legs harder and keep her barely-responsive sphincter clenched. She felt herself start to fall downwards, but she couldn't stop it yet-- she was too focused on holding it to even think about flying.

She felt her bladder try to squeeze even more than before, her eyes becoming even wider as she tried to keep it in. She so desperately wanted to just let go and use her folds to hold it in, but she wasn't sure if she could make it back to the house and take the picture in time if she did that. She knew she could do this-- just this one more time. She squeezed her eyes closed, trying and trying harder to keep her over-abused sphincter clenched.. She didn't even know how far she was from the ground-- she knew she just had to hold it. It wasn't even about clenching harder anymore-- she just had to keep her sphincter clenched enough to hold it in.

In a desperate attempt to help she squeezed her crotch as hard as she could with her hands, squirming in mid-air as she tried to cross her legs harder. She suddenly opened her eyes and gasped at the overwhelming pleasure sensation of squeezing her marehood, and she managed to make herself upright again, opening up her wings and violently catching the drift of the air, halting her fall.

She kept squirming and squeezing as she finally started to feel her intense urge go away, the pee that was so badly trying to force its way through her urethra being pushed back into her bladder. She kept squirming for a couple seconds, before exhaling loudly, panting as she tried to catch her breath. She had actually held that.. with what little control she still had of her sphincter. She couldn't think about it though-- she had to get back to her house as soon as she could. Flapping her wings, she started to fly to her house as fast as she could. She didn't care about going too fast and putting too much pressure on her bladder-- she just wanted to get there as soon as possible.

Within about a minute she finally started to arrive at her house, and just in time. Her bladder had started to spasm again, and she could already feel the pee making its way through her urethra as she approached her house. Due to her hastiness, though, she stopped flapping a little too soon, falling through the air a couple feet before landing in-front of her front-door. The impact of landing on her feet sent shock-waves through her, and she instantly started walking very fast in place-- as fast as she could as she ran over to the door.

She started to hyperventilate, opening the door and rushing inside, closing it as hastily as she can. The pressure had become too much by this point though-- despite clenching her sphincter as hard as she possibly could, she felt her pee force its way through her urethra.

"No no no no!!" She tried to clench harder, walking so fast in place her legs started to blur. She knew it was a losing battle this time though, and she felt the 'rush to the bathroom as fast as you can' reflex start taking hold in her mind. Despite that she squeezed her eyes closed, holding her breath as she tried to clench her immensely abused sphincter harder. It was hopeless this time though-- unlike the past few times, her pee kept pushing through, getting closer and closer to exiting-- too close. There was nothing she could possibly do this time to keep it in with her sphincter-- she had only about less than a second before her pee burst through and out her urethra.. Any other mare would've wet herself now, except for her.. Rainbow didn't give up easily.

Un-crossing her legs, she began to clench her puffy outer-lips, pressing them tightly against each other.. Close to immediately afterward her pee went right through her urethra, shooting out with incredibly intense force, only to be blocked from total freedom by her plump folds.. Her bladder realized this shortly afterwards, and spasmed again, trying to force its pee out. It was so close now..

The pee quickly pooled in the area behind her folds, filling it up rather quickly. Her folds began to bulge out from the pressure, but she didn't dare let them up. She kept them tightly pressed closed, keeping the pee from bursting out.. She couldn't help but stare at her pussy as she did so, almost mesmerized by it as she watched her smooth folds bulge outwards from the pressure. Her mind was over-flowing with lust and arousal by this point, and she completely forgot what she was planning on doing for several seconds as she stared.

"Right, the camera!" She wanted to stare longer, but looked back up, speedily starting to run towards her room. It felt weird to run with her folds pressed tightly together, with so, so much pee being kept behind it.. A pleasurable type of weird, though. Her bladder didn't stop spasming either, and she could already feel her folds getting tired from the immense pressure-- she had to move faster. She didn't care about how she moved or how fast it was-- she ran, completely care-free of how much it might put pressure on her bladder.. The feeling of exhilaration she got from it was undescribeable.

Upon making it to her room, she went up to her drawer, starting to look through it from top to bottom. She was surprisingly calm as she did this, the feeling of her over-abused holding muscles feeling incredibly good. Knowing her swollen bladder was still full made her feel even better about it. Upon searching through her entire drawer, though, she frowned, having not found the camera.

She quickly went over to the desk by her bed, getting increasingly desperate by the second. Her body started to tense up as her folds started to get even more tired, and she walked in place slightly as she looked through the drawer. To her dismay, though, she didn't find it there either.

"Where is it??" She started to panic slightly, her movements becoming more ridged and excessive. Her breathing started to increase as she looked around, still not finding it anywhere. She continued searching for nearly thirty seconds, before getting ready to give up and run for the bathroom. By now she was fidgeting and bouncing excessively, her plump folds bulging out a little further from the pressure, when she spotted the camera sticking outwards slightly from under her bed.

"Finally!" Wasting no time she bent over to grab the camera, that choice quickly proving to be a bad mistake as she put harsh pressure on her bladder in doing so. She gasped and her legs shook, quickly standing back up with the camera in her hands, before looking down. Her eyes widened as she saw how much further her plump outer-lips were bulging, not to mention her bladder. Her folds almost looked like they were about to be forced apart, her bladder spasming even harder in an attempt to win. She could barley keep her folds pressed together by this point due to the pressure... her bladder wanted to empty, now. With nearly three entire days of pee being trapped inside, it didn't want to wait any longer.. and the pressure from her bladder was starting to become too much for her.

Her bladder didn't stop spasming. She felt it squeezing, forcing its pee even harder against her smooth and puffy folds. She groaned, feeling her folds very slowly start to be forced apart by the pressure.. it was as if she couldn't press them together any harder. She had to hurry. Unlike with her sphincter, she couldn't push the pee back into her bladder with her folds. It simply stayed there, pushing harder and harder at a constant and ever-growing pressure..

She quickly turned on the camera and pointed it downwards, her entire body shaking from the anticipation and desperation. She groaned louder as she tried to stay still, managing to focus the camera. Only about a second now... *Snap* Her eyes widened. It was finally done. She actually managed to..

The lens cap was still on.

She silently cursed to herself, ripping the cap off and hastily throwing it on her bed. Her bladder spasmed again though. This time, it was much worse than all the other ones.. She squealed again as she felt it push against her folds, which were straining too much now. She could visibly see her outer-lips start to quiver now.. trying everything she could to keep them pressed together. She couldn't keep doing this.. her folds began to swell even more, barely managing to keep it back.. but it was becoming too much. Her plump outer-lips were finally reaching their limit...

A small amount of pee began to trickle out through her smooth folds, her bladder being ever so relentless to force it out.. Her eyes widened and she gasped lightly as she noticed it-- she was beginning to lose it. She squeaked, trying as hard as she possibly could to clench her outer-lips harder and stay still. Focus..

*Snap*

She did it, but there wasn't enough time to feel excited. She was about to wet herself in her own room! She always had a thing against wetting herself.. to her it was the worst thing imaginable-- especially if she's already inside her own house. She either peed willingly, or didn't pee at all, ever. She had to make it to the bathroom, and she was going to have to run as fast as she could. The least she could hope for is that she didn't make too big of a mess..

She threw the camera on the bed, and quickly ran out of the room, holding her breath as she did so. She moaned and squealed as she tried to clench her folds harder, managing to momentarily stop the trickle, but she knew that wouldn't last long. Her bladder kept trying to squeeze harder, the amount of pressure she was feeling almost equaling that of an orgasm. She was so aroused and her pussy was so hyper-sensitive and swollen at that moment that she felt like she could have a mind-blowing orgasm if anything managed to just press against her pussy anyway.

It didn't take long before she made it to the bathroom, feeling the cool air blow against her naked body due to how fast she was running. She didn't even bother closing the door as she ran inside, her pee starting to trickle through her tightly pressed folds again.. she had never been this desperate in her entire life. She wasted absolutely no time opening the lid, almost immediately sitting down afterwards. The first thought that came to her mind was to let go-- just let everything go and relax. For a brief moment, though, she remembered about how she had wanted to always keep her bladder full, the thought of it always turning her on. She didn't relax just yet, holding her breath and puffing out her cheeks as she looked down.

What she saw managed to turn her on so much, she didn't even know it was possible to be that horny. Seeing the pee trickle out of her folds, and the massive size of her bladder almost made her heart skip a beat in arousal. She had already begun losing it, though, despite still trying to press her puffy outer-lips as hard as she could together. She watched as her quivering folds began to spread apart faster, the small trickle pee slowly starting to become bigger.. There was absolutely no stopping it now. Her pee was going to come out no matter what this time..

She tried in vain to hold it-- trying to clench her holding muscles and her folds at the same time-- anything to try and stop it, but it was hopeless. She couldn't even slow down the stream now; there was just too much pressure and she was too exhausted.

A couple seconds went by.... then this was it. Her swollen, bursting full bladder spasmed, her folds instantaneously spreading apart as she relaxed them. Her pee had finally burst through to freedom, loudly splattering into the toilet. Her bladder had finally won, after so many days and so much effort to keep it in..

In her over-flowing arousal, she grabbed her pussy, feeling her pent up pee get all over her hand, before squeezing it. Pleasure she had never felt before in her life soared through her, as her hand and folds squeezed against her clit, her pee splattering everywhere now, getting all over her. Placing her other hand on her bulging and over-filled bladder, she began to press it, screaming loudly in astronomical pleasure and pain, rubbing her pussy as hard as she could with her hand. Her mind became completely numb with pleasure as her pee flew in every direction like a sprinkler.

She kept screaming, feeling her pee get all over her, before her orgasm hit her. She screamed even harder, rubbing her clit so violently it hurt, feeling as if her pussy was erupting from the pressure.. She fell back on the toilet as she rubbed, pee and cum shooting past her exhausted folds, everything in her body relaxing as her orgasm seemed to take her away from reality.

She didn't dare stop rubbing, spreading her legs as her entire body fell limp in pleasure. Pee and cum continued to spray out of her swollen and throbbing pussy as she rubbed, her entire naked body starting to get lightly covered in it. This moment of ecstasy lasted for almost two minutes, before she relaxed, completely covered in sweat and panting hard as her orgasm stopped, pee still weakly flowing past her folds. She panted as she let everything in her body continue to relax, never feeling so mind-blowingly good in her entire life. After about half a minute her stream of pee finally started to die down, before stopping, some remnants dripping off her folds. She just lied there, basking in the afterglow, not believing the pleasure she had just experienced.

Eventually after several minutes of just sitting, she looked down at her bladder, which was now completely empty and flat against her body. Over two days of pee had finally been emptied... past her holding muscles, and past her plump folds... She placed her hand on it, rubbing it a little, not used to the feeling of it being so empty. She eventually looked at her marehood, her folds laying limply to the side in exhaustion, exposing the inside of her beautiful pussy, drops of pee still inside, almost making it glisten with yellow.

She stared for a few seconds, before slowly getting up, feeling utterly exhausted. She slowly walked to her room, a couple drips of pee dripping off her folds in the process, before letting herself fall on the bed. She moaned deeply as she closed her eyes, gripping the covers lightly before quickly falling asleep, her body still completely exposed as she slept.

She eventually woke up the next morning, groaning lightly as she rolled over onto her back. Opening her eyes, she stared up at the ceiling, exhaling slowly in relaxation. Something didn't quite feel right.. the room felt a little colder than usual, but in a slightly different way.

It took her awhile to realize she still naked. Upon remembering why, she began to remember the events of the previous day, causing her to smile. She had held it for so long.. and successfully. As she sat up, she couldn't help but think she was forgetting something.. something important..

Her ears perked up as she remember about the camera! She got up off the bed and looked for it, eventually finding it on the floor next to her bed. She proceeded to bend down to pick it up, very curiously checking the image afterwards. Her eyes widen slightly in arousal as saw it.

It looked.. perfect. It showcased her bulging bladder, completely full to the brim... and her plump, puffy folds.. swollen and puffed out further than usual.. drips and trinkles of pee being sprayed out.. the sight of it turned her on immensely. To see herself on the verge like that.. her marehood so puffed out.. pee trickling through.. She knew what she was going to fap to for the next few months, as narcissistic as that might be.

She couldn't help but think, though, that she could last longer.. There was no way that was her limit. She knew she could last longer than that.. At least to three days. she just knew it. She was sure she could've at least clenched harder, or done something to hold it in longer. It couldn't of been her real limit. For now, though, she was going to take a small break from holding it. She decided to try and train herself in the meantime however-- there was no way she was going to let herself not make it to three days. That was going to be her goal to strive for from now on..

Proving Herself
