The next day...
"Twilight catch!"
The unicorn filly blinked in confusion and perked her head up, only to feel a ball thudding off of her head and then bouncing on the grass below. Laughter followed from the other foals that she was surrounded with.
"It hit you right in the head!"
"I threw it slow at you Twilight! Howcome you didn't see it?"
Twilight Sparkle blushed in embarrassment as she looked at the other foals. "I guess I wasn't paying attention."
The morning sun was shining down across the field that her and her friends were playing on. If anyone had been watching Twilight closely enough, they would've been able to take a guess as to why she wasn't paying attention based off of her stiff hind-legs that never moved too far apart. Twilight had taken her excitement of the new game she had come up with to heart by refraining from peeing when she woke up that morning. The filly had hurried out of her home without taking the time to empty her bladder-- a decision that she was already feeling the effects of and sooner than she expected. The urge she was feeling down below was distracting, and it was definitely making this occurrence of playing ball with her friends alot different. She was going to have to pay attention to holding in her pee and playing with her friends at the same time.
Twilight breathed in deeply, idly tapping each of her hind-hooves against the grass as she shifted her weight back and forth. The idea of being worried over other ponies seeing her be so fidgety wasn't even a thought in her mind as she watched the ball pass through the air from foal to foal. She narrowed her eyes, tapping her hooves faster and faster in anticipation the longer she watched the ball. She was going to have to stand up on both of her hind-legs so she could use her fore-hooves to hit the ball whenever it came to her. A brief moment of panic overcame the filly the instant she saw the ball heading in her direction, and she stood up on her hind-legs, smacking the ball with her hooves harder than she intended to. The ball was sent flying far away from the other foals, where it bounced and rolled across the grass until it splashed into the river that flowed just outside of Canterlot. Twilight was quick to fall back onto all four of her hooves, where she pressed her hind-legs together and squirmed her flank back and forth while the other foals groaned.
"It's gonna float away now!"
"Twilight get the ball before it's lost!"
Twilight perked her head up to see that all of the other fillies were now staring at her, and she didn't know why. Was it because she was doing a pee-pee dance on the grass? They didn't know about the game! Twilight opened her mouth to speak up, but then hesitated for a moment when she caught onto why they were really staring-- she had hit the ball too far and were waiting for her to go get it.
"I'm sorry everyone!" Twilight called out. Taking a deep breath and without much thought to it, Twilight hastily began to sprint across the grass so she could catch up with the ball. It was floating down the river rather fast, and her hooves trampled against the grass, jostling the little organ behind her lower-abdomen. Although small and unimportant most of the time, her bladder was quickly giving her reasons why she should respect it. Halfway to her destination, Twilight let out a little gasp, and her thighs tensed as she abruptly found her need to pee becoming the fore-front of her mind.
'Oh my gosh I have to PEE!!!!!!' The little filly's eyes began to widen as she felt such a looming sense of pressure between her hind-legs. She wouldn't stop running though, and instead only ran faster in naive hopes that she could out-run her bladder's demands to be relieved. Her hooves moved faster and faster, treating her filling bladder like a rag-doll which was screaming inside Twilight's mind telling her that it was going to start peeing.
'AAAAAAHHHHHH!!!!!!!!' Twilight felt like she had tunnel vision as she only tried to sprint faster. Twilight's teeth clenched, and she squeezed her eyes closed for a moment as she tried her absolute hardest to clench her down below muscles. 'I-have-to-pee-I-have-to-pee-I-have-to-pee!!!!!!!!!!!! Why can't I--whoa!!!!!'
Opening her eyes back up, Twilight was caught off guard to see that she was about to sprint right into the river. The little filly scrambled to stop herself, grinding her hooves against the dirt until she slipped and fell onto her flank. Twilight squeaked at the shockwaves the fall sent across her bladder, and the moment her flank thudded against the ground, she let go. Twilight felt an overwhelming amount of relief the second she finally laid rest to her tired down below muscles... and upon feeling her warm pee start to sprinkle out from between her hind-legs and get on her thighs, Twilight let out another gasp. Twilight spread her hind-legs and then looked down between them, too shocked to believe that she was actually peeing until she looked at her little marehood and saw it herself.
'NO-NO-NO-NO-NO I CAN'T PEE OUTSIDE!!!!' Twilight's cheeks flushed bright red as she hastily stood back onto her trembling hooves. Her parents taught her to only pee in the toilet, or else she would get in trouble! She tried at first to stop the flow and hold it in again, but she felt so completely powerless against the stream of pee that was eagerly torrenting past her little marehood. Her down below muscles felt numb and it also felt so relieving to finally let her pee flow out and get all over her tail and run down her hind-legs... and then she could feel the pressure at her back from what she could only imagine as her friends and her parents just watching her. Twilight wanted to curl up and hide somewhere, and seeing the river in-front of her, she quickly saw it as her only escape. Taking a deep breath and puffing out her cheeks, Twilight hastily dived into the water before she could leave anymore droplets of pee sparkling on the blades of grass behind her.
"M-mmmn..." Twilight closed her eyes and moaned as she felt the water completely engulf her. She felt hidden and secure underneath the water, where it made her feel more comfortable with letting all of her pent up pee continue to flow out from between her legs. She couldn't believe she had needed to pee that badly.... and eventually feeling a tang in her chest that told her she needed to breathe, Twilight raised her head up above the water and held onto the side of the river to keep her body held above the surface.
"Are you okay Twilight??" The voice of Twilight's mom called out. The little filly perked her head up to see her parents running over to her from across the field.
"I.. tripped!" Twilight gulped and pushed herself a little further into the water out of fear of being punished. She had never experienced anything like what she had felt when she was running... and she shivered when she thought back to it. Her intense urges to pee had left her so on edge and running faster than she had ever done before, like a trembling, runaway need that she just couldn't satisfy until the dam broke between her hind-legs. Twilight then watched as her dad's horn started to glow, and the ball that she was chasing after was levitated out of the water and placed on the grass beside them.
"I'll go get a towel so we can get you all dried up." Twilight's dad exclaimed before walking off. Twilight then fearfully looked over at her mom, but to Twilight's surprise so far, she didn't appear to be upset.
"That's gotta be a record for how fast we've ever seen you run!" Twilight's mom spoke with a short laugh. She then trotted over to the little filly to help her out of the water, where she finally noticed just how worried her daughter looked-- a face that was all too familiar to her. "You're not going to get punished for tripping into the water, silly-willy!"
Twilight perked her head up and blinked. Was her mom not going to say anything about how she peed herself? Maybe she didn't even notice! Twilight felt a wave of giddy excitement at the thought of getting away with her little accident, and she lowered her head, trying her best to hide how much she was smiling and giggling. 'They didn't notice!!! They didn't notice oh my gosh!'
Twilight stood on the grass with water dripping down her fur for a couple more minutes until her dad came back with a towel. Once she was dried off, the hyped up little filly shared a few warm nuzzles with her parents before running off to play with the other foals again, all while excitedly thinking about what it was going to be like the next time she tried to hold in her pee.
Twilight Sparkle's little heart pounded as she laid down in her bed tucked comfortably under the covers-- as comfortably as her body would allow. A light shimmer of sweat formed all across her body as she restlessly squirmed against her mattress. The little filly was in a dire situation... a direness caused solely from the precious organ that was housed within her lower-abdomen. An organ that was full and mercilessly demanding for only one thing: to be relieved. Twilight needed to pee badly, but there was nothing she could do about it right now.
"Why aren't they in bed yet??" Twilight whispered to herself. Her face scrunched up, and she squeezed her eyes closed, quietly groaning and then repeatedly bouncing up and down on the bed. Her filling bladder's urgency was taking its toll on the poor young filly, making her fidget excessively in her attempts to hold back the flood. A wave of worry swept across the filly's mind-- she couldn't possibly wet the bed! She was way too old for that now! Twilight sharply breathed in through her clenched teeth, narrowing her eyes and clenching her muscles down below as tightly as she could. Her thighs were tense and grinding against each other as she bounced her flank repeatedly against the bed. She was struggling, but she had a determined look on her face. She just had to hold it for a little while longer, and then she could give her bladder the relief that it so desperately wanted.
"Mmnnrgh...." Twilight groaned, burying her face into her pillow as she fought against her bladder. Her ears were perked up and were listening to what was happening just outside of her bedroom-- the sounds of her parents still doing whatever they were doing in the rest of the house. She had to wait until they were in bed before she could escape her room and run to the bathroom. Twilight was supposed to have gone to sleep hours ago, and she dreaded wondering how her parents would react if they knew that she was still up. She just had to wait until they were in their room, and then she'd be able to go to the bathroom and back undetected-- they'd never have any idea that she was still awake. Her bladder harshly spasmed, and the little filly gasped quietly, cementing her hind-legs together as tightly as she could and then squeezing the hardest she could manage.
"M-mmn..!!!!!" Twilight's eyes were wide. She had to pee so badly, and to feel how close it was getting and how relentless her bladder was being was causing her to go from worried to scared. The filly stared blankly in-front of her, focused solely on the little ringed muscle which was serving as the only barrier between keeping her bladder neatly contained, and making an enormous mess on her bed. Although she was only a filly, she was smart enough to know what was going on. She didn't know what it was exactly, but she knew that the effort of squeezing down there was what she had to do to keep herself from peeing. Under that logic, all she had to do was keep squeezing no matter what.
'Come on Twilight... You can do this! You're old enough to hold in your pee like an adult can! You just have to squeeze. Squeeze and squeeze and... mmn!!' Twilight's train of thought dissipated when she felt her bladder contract again. She quickly inhaled, holding her breath and squeezing as hard as she could manage. Her thighs were tense and rigid, and her hind-legs were trembling from how hard she was pressing them together. Her expression displayed so much strain as she forced that little muscle down there to clench as hard as it could. She had to tell herself that she was a strong filly-- a filly that was capable of holding it in for just a little longer...
As a few more minutes passed, Twilight was starting to reach her breaking point. The control she had over what she referred to as the 'down below muscle' felt so non-responsive. Her bladder had gotten so full and was protesting so angrily against that poor little muscle that was trying its best for so long. Despite how late it was, Twilight felt wide awake, worried that she might not be able to hold it anymore at any minute. The sound of her parents making their way down the hallway to their bedroom sparked sudden excitement in the filly-- she was almost there! She just had to hold it for the tiniest bit longer....
Twilight squeezed her eyes closed, pretending to be asleep when her parents trotted past her bedroom. Her bedroom door was open, so she had to at least look like she was sleeping in-case they looked inside. Despite trying to be as still as possible, her body was trembling constantly from the strain she was putting on herself to hold in her pee. It was almost time... She could feel her over-filled bladder quickly getting excited as she imagined how close she was to running to the bathroom and sitting her flank down on the toilet. That excitement and premature celebration was wreaking havoc on her ability to keep holding it, and she winced, breathing shakily and squirming her flank excessively back and forth against the bed. She needed to pee so urgently and it was leaving her with her limbs all tucked tucked in so close. She crossed her hind-legs as much as she could in her frantic attempts to do whatever she could think of to help keep all of her pee securely contained. Her ears were perked up, listening intently at the sound of her parents quietly closing their bedroom door... And then she waited. She wanted to wait at least a couple minutes to be safe in-case they went back out, but after only ten seconds, she just couldn't wait anymore.
'I have to pee so bad!!!' Twilight thought to herself. Alarms were going off in her mind, and she scrambled out of her covers and onto the floor. The moment she had her hooves on the ground, she had to stop for a moment so that she could do the most frantic, desperate looking pee-pee dance she had ever done. She walked in place so fast that her legs looked like a blur, and she arched her head back, squeezing her eyes closed and then letting out a little squeak. To be on her hooves was driving her eager bladder nuts as it protruded so noticeably like a little round tennis ball stuck in her lower-abdomen. It felt like a switch had been flipped in her mind that told her she was going to start peeing herself in only seconds, and with her eyes opening back up wide with worry, she now had a new goal-- not to hold it, but to make it to the bathroom before it started coming out.
'NO NO NO NO!!!!!!' The little filly took off sprinting at full speed. Her ragged movements mercilessly joggled her firm, bloated bladder, but she couldn't care anymore-- all she could think about was reaching the toilet. With her stuffed bladder having reached its limit, Twilight could feel her last strands of control breaking apart as she rushed down the hall. Her bladder felt like it was angry now, and despite the fact that she was still squeezing that little ringed muscle that was supposed to hold it in, it didn't feel like it was enough anymore. Her pee was pushing through anyway, and her pupils shrunk down to a tiny size when she realized she was losing control. The moment her self-proclaimed down below muscle felt powerless to hold it anymore, she simply let it go, relaxing it completely at the same time she charged into the bathroom. She was starting to pee and she could recognize the feeling-- the feeling of her pee working its way through her urethra. It didn't have to go very far to reach the exit, and Twilight's hooves trembled when she felt it start to come out at the same time she opened the toilet lid. For about a second she could feel her warm pee streaming onto the floor and splattering against her thighs before she swiftly sat down onto the toilet. She couldn't believe how close she was, and she covered her mouth with her hooves, trying to pant as quietly as she could as her pee furiously streamed out from between her thighs.
"O-oh my gosh..." Twilight muttered with a muffled voice. It felt so heavenly to finally let go and allow her bladder get relief after fighting it for so long, and she soon closed her eyes, lowering her head and calming down. Twilight knew what had happened-- she had lost control over herself, and she was lucky she had gotten to the toilet when she did. She couldn't imagine lasting even another second. The filly exhaled slowly, removing her hooves from her mouth and then resting them against her hind-legs. After holding it for so long in her bedroom, she was finally able to pee... and to know that she had made it to the toilet first made it so much more soothing. Twilight's stream of pee lasted longer than she ever remembered it being before it slowed down to only drips, and after squeezing the last bits out, she cleaned herself off and stood up from the toilet. Flushing would be too loud, so she just closed the lid and went back to her bedroom-- her parents could just blame that on her brother again.
Making her way back underneath her snuggly covers, Twilight found herself thinking about the little adventure she had just been on. The whole experience had been alot of fun, and the thought of doing it again made her feel excited. She didn't know why, but the frantic feeling of desperation and holding it for so long made her feel a strange way that she enjoyed. It was like a fun game! The filly smiled widely in excitement and clutched her pillow.
'I need to do that again! That was like having a mini-adventure! Now I know something I can do tomorrow.' With an eager smile on her face, the filly found herself having difficulty getting to sleep because she couldn't stop thinking about what it was going to be like to hold in her pee like that again. She decided that she would turn it into a game-- a game where she would try her best to hold it in as long as possible.
