Saimon

Three girls sat watching TV one night; Dana, Madison, and Sasha. Madison found herself absentmindedly squirming in her seat.
“Damn, I gotta pee,” she muttered, but didn’t get up.
“You hold your pee way too much,” Sasha told her, “you’re gonna get a UTI. The bathroom’s right there.”
“Maybe if I hold it for a really long time, my bladder will stretch and I’ll won’t have to pee as much,” she joked. Her bladder was annoyingly small.
“That logic is stupid and you should go to the bathroom.”
“I mean,” Dana said, “it kind of makes sense.”
“No it doesn’t,” Sasha said, “I don’t eat more now so I can eat more later.”
“You can if you wanted to,” Dana replied.
“You really think it makes sense?” Madison asked, fanning her legs. Dana shrugged. “A little bit.”
“I’m gonna try it then.”
Sasha sighed. “I swear, if you pee on my couch.”
“I’m not gonna pee on your couch,” she said. She thought about it for a second, then got up and got a towel out of the bathroom and put it down to sit on.
About a half an hour later, she was squeezing herself intermittently and constantly fidgeting.
“How’s it coming along?” Dana asked.
“I really gotta go,” she giggled a bit.
“Maybe you should put on your bathing suit so you don’t ruin your pants.”
She had white shorts on. “Yeah, I’ll be right back.” She ran upstairs, liquid sloshing around inside her with every step, and got her rainbow one-piece. Madison danced around and held herself as she stripped naked. She went into the bathroom when she was completely nude and looked for a bladder bulge, but there wasn’t one yet. She glanced longingly at the toilet before going back to the room and pulling on her suit, which was a bit too small for her. Then she went downstairs and sat back down on the towel, still badly needing to urinate.
Another half hour later, she couldn’t sit still to save her life. Madison was constantly scooting back and forth, squeezing herself tightly and writhing around, desperately trying to keep herself contained.
“How’re you doing?” Dana asked.
“I have to pee so bad!” she gripped herself and doubled over. “I’m really bursting...”
“You gotta hold it in, though.”
Madison took a deep breath before sitting up. “I’m gonna go check if I have a bulge.” She got up and made her way to the stairs.
“A what?”
“A bladder bulge,” she stood there squirming and stepping around, “like, when you have to pee so much it sticks out of your belly.”
Dana didn’t know what she was talking about, so she came with her. In the bathroom, Madison pulled her suit off so it hung from her upper thighs.
“A little bit,” she muttered, trying to keep her squirming to a minimum. There was a small bump protruding out of her belly. “I’ve never seen that before,” Dana said, “even when I have to pee really really badly I don’t think it gets like that.”
“I get it all the time,” Madison said, stepping around as she pulled her suit back on. They went back downstairs and continued watching TV.
A half an hour after that, Madison was absolutely dying. Her fidgeting had turned into constant, uncontrollable writhing, and felt like she was going to explode.
“Oh my god, I can’t think about anything else!” she said, grinding her crotch into the couch. At least one hand was always gripping hard in between her legs.
“You think this is actually giving you a bigger bladder?” Sasha asked. Madison didn’t answer. She was desperately trying to keep all of her pee safely inside her body. She was starting to lose control, though, and spurted hard into her bathing suit.
“Ohhh... I went a little,” she groaned, doubling over and wiggling her butt. She was so full of liquid that she could barely even keep her hands still.
“Maybe we should do something to distract you,” Dana said. “Do you want to go for a walk?”
“It’s dark out,” Sasha replied.
She shrugged. “We could go to the pool maybe, so she can just pee in the water.”
“I’m down to go to the pool,” Sasha said. They went upstairs to change and left Madison trying to fight back the urgent need she was neglecting. She could see her tummy poking out a little bit where her pee baby was forming. She spurted again and had to wipe rivulets of urine from her thighs.
Once the other two were ready to go, Madison braced herself and stood up. She hobbled instead of walked with both hands tightly on her girlhood as they left. She left the towel she was sitting on behind in the house.
About five minutes passed before Madison had to stop walking and kneel down to make sure her screaming bladder didn’t burst before they got to the pool. When she stood back up, she had to jump around and lurch forward a bit before being able to walk again. It hurt so bad that she didn’t know how much longer she could stand it.
“Fuck!” she groaned, her stride faltering. Her pulsing bladder was stretched taut with the enormous amount of piss she was holding. “Guys, I might not make it there.”
“Just hold as much as you can,” Dana told her encouragingly.
Her bladder begged to be emptied so harshly that she felt like crying.
Another five minutes passed. They were almost there, but Madison was almost certain she wasn’t gonna make it there without any major leakage. She suddenly lurched forward, her mouth ajar in a silent groan. Urine was intermittently spurting out of her, despite how hard she was digging her fingers into herself. It ran down her shaking legs and dribbled to the pavement.
“You good?” Sasha asked, awkwardly laughing.
“Y-yeah...” she managed to choke out as her stream weakened to to a stop. “Jesus Christ, this is difficult!”
“Mind over matter,” Dana told her.
“Let’s see you try this!” Madison said, starting to walk again with her hands between her legs.
“Uh, I’m an athlete. Mind over matter is kind of my thing.”
“I still think this is harder than you think.”
“Wanna bet?”
“You’re gonna do it with me?” She wished the conversation would end so she could focus more on holding.
Dana shrugged. “I already kind of need to go right now. I won’t pee from now until after you completely empty your bladder.”
“So it’s a contest.” She winced as her bladder contracted. “A really unfair one. I already have to piss really badly.”
“You just keep holding through your leaks and whatever, and I’ll drink a shit ton of water. First to go completely loses. Fair?”
Madison nodded, cradling her bulge, which had grown considerably since the last time they checked.
They got to the pool. Sasha opened her towel, which was folded to hold her things, and immediately sighed.
“Fuck,” she swore, looking at the other two.
“You didn’t forget the key card, did you?” Dana asked. Sasha didn’t answer. She just tossed her stuff over the flat-top aluminum fence and climbed over it. Dana did the same. They left to get a table without paying her much mind, but Madison was so full of liquid that she could barely walk, let alone climb a fence. She was stepping around and squeezing herself trying to figure out the quickest way to do it. She jumped up and threw her leg over, but pee began forcefully gushing out almost immediately. She sat on the fence for a moment, grinding into the rail until her stream came to an end. She’d drained herself considerably and there was a rather large puddle underneath her, but she still direly needed a toilet. She managed to throw her other leg over without further damage and made her way to the table with her hands between her legs.
“Wow, there’s really nobody here at night,” Dana said.
“There never is. It’s not even really that crowded during the day,” Sasha responded.
“Sweet. Let’s go.”
“Wait!” Madison said, squirming and writhing in place, “didn’t you say you were going to drink a shit ton of water? The water fountain’s over there.”
Dana paused. “You’re right. The contest should be fair.” She went over to the water fountain and drank for a long time while Sasha went into the pool by herself. Madison sat on her heel in a beach chair, doing everything you could think of to keep all of her pee in. She heard a loud, revolting burp erupt from Dana.
“Fuck, I drank way too much,” she said, holding her belly. She gagged a couple times, then took a deep breath and said “I’m okay.” She took a seat next to Madison.
“You getting in?” Sasha asked.
“I need a minute. My stomach really hurts now. Like, really bad.” Dana burped again. “A little bit came up,” she muttered into her hand.
“How long until it reaches your bladder, you think?” Madison asked, sitting on the side of the chair and tapping her feet madly.
“I already gotta pee, I said,” Dana replied, standing up. “You basically have an advantage. You didn’t go out of your way to drink more. My belly feels like it’s gonna pop.” She ran and dove into the pool, leaving her desperate friend alone to keep holding.
About a half an hour later, Madison was extremely overfull. She’d kept her leaks to a minimum because she was sitting down, but they still happened. She laid on her back with her knees up and both of her hands gripping her girlhood.
“How are you holding up, Madison?” Dana called from in the pool.
“Uh, i-it’s hard to tell,” she said. “I can barely think, but I’m pretty sure I can hold a while longer.”
“I really gotta go,” Dana laughed.
Madison sat up, wincing and scooting back and forth. “How bad?”
“Pretty bad. It hit me a lot quicker than I thought. You’re still gonna lose, though.”
Madison was almost certain she was right. Dana was seriously competitive. She’d been running track and playing soccer since elementary school. Plus, she was a hell of a lot stronger than Madison was, and she figured that probably contributed to her bladder muscles.
Madison felt herself leak a bit and tightened her grip on her pussy.
A little while later, the two girls got out of the pool to spend time with Madison so she wouldn’t get bored, but her concentration was focused elsewhere.
“It’s getting so bad,” she giggled, writhing desperately. “I can’t sit still at all.”
“It was a good idea to come to the pool, right?” said Dana. “You don’t have to rush to the bathroom. Just let it go.”
“How badly do you need to go?”
“Pretty bad, I guess,” she replied. “Actually, maybe not. It feels urgent but I know I can hold it.”
“Maybe you should drink more water,” Madison said, wiggling her butt. “I mean, it’s only fair. I’m really desperate right now.”
Dana sighed, smirking a little. She made her way back to the water fountain and drank again.
“This doesn’t seem just a little bit stupid to you guys?” Sasha asked Madison, who had just tensed up completely to keep from dribbling.
“Aren’t most of the things we do stupid?”
Sasha laughed. “I guess. You should come swim with us, though. It isn’t as much fun without you.”
Their conversation was interrupted by another burp from Dana. “I didn’t urp drink as much this time,” she said. “You want to go back in?”
“Yeah, sure,” Sasha muttered, getting up. “You coming, Madison?”
“I don’t think so,” she said, squirming. It was getting about as bad as it was just before she jumped the fence.
Sasha shrugged. “Maybe we should just stay here, too.”
“That’s boring! Let’s go to the pool!”
“Yeah, I don’t want to make you guys stay here if you don’t want to,” Madison doubled over and winced as another leak forced its way out of her body. “Plus, I really need to concentrate if I don’t want to wet myself.”
“Looks like it’s just us,” Dana said, scooping Sasha up in her arms and carrying her to the pool.
“Put me down!” she laughed, “Goddamnit, Dana!”
Madison paid little attention, but as Sasha managed to escape, she heard Dana grunt and exclaim “Ohh, that was my bladder!” She glanced up and saw her do a quick but noticeable pee dance before jumping back into the pool. “Dana must be feeling that water by now,” she muttered to herself, feeling a bit of hope for the contest. About thirty minutes later, though, she was absolutely dying. It was even worse than just before she jumped the fence. The poor girl felt like she was about to explode. She was in a constant state of desperate agony, never still for even a second. Both hands were madly grabbing at her crotch as she jumped up from her chair and marched around, occasionally jumping and squeezing herself even harder. Her bladder was ready to burst and she felt like she could cry. She fought hard to keep every drop of pee in, though, because she wanted her bladder to expand as much as possible. Every position she found herself in was astoundingly uncomfortable, causing her to keep standing up and sitting back down, trying to find some way to alleviate her desperation.
“You good Madison?” Dana asked. She was sitting in a donut shaped floaty.
“No!” she whimpered, sitting back down and scooting back and forth.
Dana laughed. “Me neither,” she said, putting a hand over her belly. “It really hurts. I’m just trying to move as little as possible.”
While she was talking, Dana hadn’t noticed Sasha deviously sneaking under the floaty. She suddenly leaped up and flipped the tube, sending Dana back into the water. It was torture for her overfilled bladder. She immediately got up and started wading to the edge of the pool. “I need to get out of the water,” she moaned among Sasha’s laughter. She climbed out and laid on her back with her knees brought up.
“It’s really cold and I have to pee extremely badly,” she giggled to Sasha. “Maybe not as bad as Madison, though.”
Madison paid no attention to what they were talking about. She was too focused on containing herself. Her whole body was trembling from head to toe as she struggled to keep the pee inside her body.
Sasha had come to the edge of the pool next to Dana.
“I really wish Madison would use the bathroom already,” Dana whispered, laughing a bit. “It hurts so bad.”
“What if you just let some out in the pool? There’s no way she’d know.”
Dana gave her a weird look. “That’d be cheating.”
Sasha shrugged. Dana sat up, wincing and putting a hand between her legs. She didn’t feel like she was in danger of wetting herself, though. She just really needed to go. She got up and waddled to a chair.
Another half an hour later, the girls were still managing to keep the contest alive. Madison was on the verge of tears. The pain she felt was incredible. She couldn’t keep hot little spurts from dampening her crotch every few seconds. The poor girl was at her absolute limit. She was constantly writhing madly, desperately grabbing at herself and rubbing between her legs. Every nerve down there was on fire. She could feel the shape of her bloated organ pulsing in her body, which made her feel a bit squeamish.
Dana wasn’t doing too much better. She sat in her chair bent forward a bit, biting into her knuckle from the pain. When her immense discomfort made her shift positions, she tried to move as little as possible as to not jar her bladder, which bulged out of her like a small melon. This method of holding was not practiced by Madison at all. She continued to squirm, writhe, bounce, and jiggle as much as possible.
“God, I can’t take it!” Madison moaned, leaking more hot urine into her bathing suit. In an odd way, though, the unbearably overfull sensation of her screaming bladder felt really good between her legs. All the rubbing and squeezing was almost like she was masturbating, but it wasn’t just that. Her need to urinate alone was turning her on.
“You almost done?” Dana asked with fake confidence, her enormous bulge throbbing in pain. Madison shook her head, grinding into the chair. 
“I can hold it for a while longer,” Dana lied, “you look like you’re at the end of your rope. I think your bladder is pretty stretched out by now, right?”
Madison filled her cheeks with air and lurched forward, wiggling her butt and squeezing herself hard. A particularly powerful spurt had come out as a result of her relaxing her muscles for just a moment. Her muscles were so tired, and her urethra was stinging badly. Pee was dripping to the pavement from underneath the chair.
Over the next twenty minutes, her leaks were getting bigger and bigger. There was so much liquid inside the poor girl that her body was beginning to take over. It hurt so badly that she couldn’t stand it, and the intensity of her writhing and squeezing was borderline humiliating. If she had anyone other than her closest friends around, she’d be mortified. It genuinely felt like her bladder was going to burst.
Dana was also in immense pain. She was worried that she was doing actual damage to her body by holding so much. When she wasn’t encouraging Madison to forfeit, she was taking deep breaths to take her mind off her agonizing need.
“I gotta fart,” she muttered, making Sasha giggle. She lifted her ass a bit, but her urgent need protested in the form of searing pain. The desperate girl really needed to pass gas, though. She pushed a bit, letting out a rather long fart, which was unfortunately cut short by a small leak. Dana’s eyes went wide, and she wondered how much longer she could last.
“Madison, you really can’t win this,” Dana told her, watching her friend struggle to contain her fluids. “Face it, you’re filled to capacity.”
Madison wasn’t going to budge, though, even though she knew it was true. She was leaking heavily every few seconds, as if she was emptying just as fast as she was filling.
Dana winced as she went to change positions, but changed her mind as her enormous, liquid-filled belly sent urgent signals to stop moving. ‘God, I need to piss,’ she thought miserably, gently holding herself with one hand. ‘Even though I leaked before, it still doesn’t feel like I’m gonna pee my pants. It just hurts. Jesus Christ, it hurts...’
She absentmindedly watched her friend’s pee dance, silently urging her to relieve herself as if she had some kind of telepathic ability. Madison was scooting back and forth with her legs spread and both her hands rubbing between her legs. She looked ready to cry. Dana saw her spurt again. It was so powerful that it formed a stream for a moment before she locked her legs back together and dramatically fell on her side, digging her nails into her girlhood.
“It hurts so badly,” Madison whined, urine streaming down her legs and dripping to the pavement.
“So go!” Dana said, but her friend stayed where she was. “Madison, your body has a limit. You’ve got to pay attention to your bodily functions.” Dana’s bladder was so tight and full that it felt like it was going to rip. A warm soreness was spreading into her kidneys. “A-Are you really not gonna go?” She asked. Madison shook her head. Dana touched her fingers to her belly and felt her screaming organ stretched taut up against her skin.
“I-I-“ Dana stuttered. She’d never lost a contest before. She’s lost soccer games, but every little contest her and her friends like to make she’s dominated. Her bladder was in searing agony and her lower back was throbbing badly. “O-Okay, Madison, you win. You win, dude.” Dana struggled to get out of her chair, careful not to make any sudden movements.
“Really?” Sasha asked, “damn. You never lose, Dana.”
The words hurt her confidence, but her belly hurt worse. When she tried to put weight on her feet, she felt herself leak again. She winced and flumped back down, groaning.
“I can’t stand up,” she said. Sasha laughed, but Dana didn’t think anything was funny. Madison was paying very little attention, focusing on containing herself as much as possible.
Sasha reached over and tapped Dana hard in the stomach. She yelped and pleaded for her not to do it again, but her friend only laughed.
“Just pee your pants already,” Sasha told her. “You’re in a bathing suit. Jump in the pool and go.”
Dana hesitated for a moment, then took a deep breath and relaxed. It took a minute for her stream to start, but when it did, it shot out of her and loudly splattered to the ground. She let out a shuddery sigh of relieve as her screaming, overbloated bladder finally drained. Her kidneys ached, but she felt such intense bliss as she let go. Madison turned away from the display, accidentally letting out a rather large spurt. An enormous puddle spread from under the chair and travelled to the poolside, dripping off the edge. After what seemed like an eternity of pissing, she jumped into the pool and floated on her back.
“That’s nasty,” Sasha said, and jumped back into the pool with Dana, once again leaving Madison alone with her unbearably swollen bladder. She wondered if she would ever actually wet herself completely, or if she would just keep involuntarily leaking. It seemed like when she’d peed herself as a little kid, she gave up after the first big leak because the damage to her clothes was already done. She wondered how long it would take for her muscles to actually completely give out. She also wondered if when she reached her maximum bladder capacity, if the leaks would keep happening and her need never got worse. This odd curiosity was one of the few remaining reasons that made her keep holding her pee in for another ten minutes after that, when she was absolutely dying. Urine was always trickling out of her, dripping down her legs and soaking everything around her with pee. Her pathetic, constant stream fluctuated in strength, but never stopped or grew to a normal pee stream. Tears were welling up in her eyes as she dug her crotch hard into her heel, yellow liquid traveling down her feet. If she had pants on, her clothes would be so drenched in urine that she could have completely emptied herself into them and it wouldn’t have made her situation worse, but she wasn’t holding to keep dry. That ship had sailed a long time ago.
She wasn’t completely sure why she was still holding; to expand her bladder, to win a contest, to find her limit... It was also making her crazy horny, but there’s nothing she could do about that with her friends right there in the pool. Truthfully, she enjoyed the fullness in a really odd way. It’s why she held it so often, but she’d never had to go this badly.
Her eyes watered, her pussy was tingling, and she felt like she was about to pop. She’d been enduring her unbearably overfilled bladder for hours and she wasn’t sure how much longer she could take the constantly growing pain. She slipped her fingers inside her bathing suit, rubbing vigorously and clutching at herself. She was still constantly leaking and dribbling. Urine suddenly squirted out as her bursting bladder contracted, quickly reverting back to leaking in a matter of seconds.

In an undisclosed location lies a school for students with unique abilities and gifts. These abilities can include flight, invisibility, super strength, et cetera... This school is meant to allow these students to explore and hone their skills, so that they can safely control them out in the real world.
Stepping into this school for the first time is a young girl named Paisley. She had a plaid skirt, a white shirt, thick glasses, braces, and blonde pigtails tied tightly back, the stereotypical nerdy little girl in the body of a teenager. She shuffled shyly through the hall, where students were practicing miraculous things. There was a boy reading a book while floating in mid-air, and a girl heating up her coffee with her hands alone. Paisley had powers of her own, of course, which is why she was sent to this school, though she didn't see a reason for it. Her power was invincibility, literally the safest possible power to have. She wasn't a danger to herself and others at all. Still, her mother sent her to this school to learn to control her powers. Or perhaps she only wanted her to meet some friends, something she never really knew how to do in regular school. Unfortunately, she was just as shy in this school as she was in the last.
She pulled a crumpled map of the school from her bag and found the way to the girl's room. There were a few others in there as well, but she paid no attention to them. She flumped her bag down on bed 73 (the bed number printed at the top of the map) and took a seat at the foot of it, gazing out of the window that was placed conveniently next to it.
"Hey," she heard someone say. She turned and saw a girl, a bit younger than her, with black braids and dark skin. She smiled widely at her. Paisley half-smiled back, closed-mouthed as to not show off her braces too much. "My name's Breanna," the girl continued, "what's yours?"
"Paisley."
"That's a pretty name. What's your power?"
"I'm invincible," she said quietly.
"Whoa! That's awesome," Breanna said, "so you can't die if someone, like, shoots you?"
She shook her head.
"Huh. That's weird."
Paisley looked out the window again.
"I can move electricity," Breanna said.
"Cool," Paisley murmured, not taking her gaze from the window.
"See, watch." She got up and touched a lamp, causing the light to flicker for a moment. Then she walked over and touched Paisley on the arm. It shocked her rather badly.
"Ow!"
"See? I usually only do it a little bit from a battery or something, but you said you were invincible."
"I still feel it..." she muttered, rubbing her arm.
"My parents found out that I'm super when I was really little. I would turn on the TV just by touching it and stuff. I'd always zap my brothers when they were annoying, then I'd say it was an accident so I wouldn't get in trouble, which is why they sent me here I think, but I have pretty good control over my power. How'd you find out you were super?"
 "I ran out in front of a car once when I was really little, like three or four. I had no marks at all when I got back up."
"That's crazy. You could be a superhero or something. I'll be right back, I gotta pee." Breanna got up and left the room. Paisley felt a faint ache in her bladder, and wouldn't have minded going herself. She thought it'd be awkward to follow Breanna there, so after  she got back, she waited about five minutes before asking.
"Could you tell me where the restroom is?" she asked.
"It's the first left when you go down the stairs on your right," Breanna explained. Paisley followed these directions, but when she reached her destination, her heart sank. It was a multi-stall bathroom, one with a couple other people in it already. She hated these. She could never relieve herself when other people were in there. She even found it impossible to go when she was alone in one with the possibility of other people entering was looming over her. She returned to her bed and looked out the window, but it wasn't long before Breanna started talking to her again.
"So if you're invincible, does that mean you don't have to eat?"
Paisley giggled. "I don't have to, but I feel hungry and thirsty. If I chose not to eat, I wouldn't die, but I would feel like I'm starving."
"Ohhh, that's weird." The two talked for a long time, and Paisley gradually opened up more and more, until one of the professors called "Lights out in ten!" All the girls promptly changed into their pajamas, and most went down to brush their teeth. Paisley shyly put a shirt over the other, then removed the shirt underneath. She did the same with her pajama shorts, which were much easier because she was wearing a skirt. Then she brushed her teeth and went to bed. "Night," Breanna said, as the whole place went dark. Paisley laid down, but couldn't sleep very well. It was about an hour into the night when the aching in her bladder was becoming more intense. This was the moment she was waiting for to go, though, when the entire school was quiet and nobody was (probably) in the bathrooms. She got out of bed and crept outside, and was immediately met by one of the professors.
"What do you think you're doing?" she hissed.
"Th- uh, I need to go to the restroom, ma'am."
"You can't leave the bunks at night! Go back to bed."
She went shamefully back to her bed and tried to sleep. When she woke up in the morning, she really had to go. The fidgety girl changed into a clean shirt and skirt and rushed to the bathroom, where, unfortunately, was a crowd of girls all brushing their teeth, showering, and relieving themselves. Paisley couldn't bring herself to pee with all those people around, so she simply brushed her teeth and went to breakfast.
"Sit with me," Breanna told her in the lunch line, nudging her arm. She did. There was another girl and two boys there. The girl introduced herself as Dana, and the boys introduced themselves as Benny and Blaine. They were twins. They talked and laughed all breakfast long, though Paisley contributed very little to the conversation, due to her shyness and her distracting need. She was rather hungry, though, and had her breakfast with a tall glass of orange juice. After that, she went to her first lesson.
"So," her professor said, reading a single paper from an envelope. "You're invincible, but you can still feel pain?"
Paisley nodded her head, squirming a little in her chair.
"You don't have any other power, correct?"
Paisley shook her head and crossed her legs, tapping her jittery fingers against her legs.
"You nervous?"
She shrugged. Her professor laughed. "Well," she said, "invincibility is a form of stagnant ward, which means you may have the potential to wield some sort of forceful power. The pain you feel, though," she scratched her head, "it's an interesting situation. It could mean some sort of healing magic. Would you want to be a healer?"
Paisley shrugged again, tightening her legs.
"You should think about it," her professor told her. The rest of the time was more technical things. She learned how she can grow her powers and morph them into what she wants to be. At lunch, she sat at Breanna's table again and they talked about it, though she avoided conversation as much as possible. She needed a toilet really badly now. Her full bladder felt like a bowling ball in her tummy, pulsing with every step she took and aching with every moment she didn't give it relief. Still, she ate her lunch and drank a lemonade.
After lunch, they were allowed outside in the courtyard. It was a very beautiful place. The grass was green and the yard was huge. There was a tall fountain in the center of the courtyard, but it wasn't on, luckily for her. Paisley paid little attention to the scenery anyway, since her belly was so full of hot piss that she could barely concentrate. Breanna invited her to play frisbee, which she denied for obvious reasons. She stayed back alone and tried her best to get lost in a book. Every few seconds, she had to change positions when she felt too uncomfortable. The constant throbbing was making it impossible to read. After that, the students were led back inside where they were taught standard topics to make up for what they were missing in school. Then they left for dinner.
Paisley ate her pork chops with a glass of milk. She was discreetly rocking back and forth in pain, caressing her bladder whenever no one was looking at her. Dinner ended, but when she stood up, she nearly fell back into her seat. Paisley was absolutely bursting at the seams. She could barely stand up straight, and it hurt to walk. She waddled her way to the bunks and sat down until lights out. She didn't bother brushing her teeth, she just laid down in her bed and curled up into a fetal position. By that point, most girls would have wet themselves, but Paisley wasn't most girls. If you remember, she can go as long as she wants without food or water, but she'll feel like she's starving. This applies to all other bodily functions as well. She's never thrown up, even when she felt so nauseous she thought she'd die. She's once stayed up for an entire week binge-watching a show without ever passing out. She's also never wet herself after her potty training. It was part of her power. So poor Paisley laid there curled up in pain, her bladder begging to be relieved. It took her a long time to fall asleep, but she did, and when she woke up in the morning, it was an absolute emergency. 
Paisley felt like she could cry. Her rock-hard bladder had begun to protrude out of her belly, pulsing and throbbing and hurting to no end. She sat up, gritting her teeth, and changed into her regular clothes. Bending down was excruciatingly painful, but she stifled her moans. The poor girl waddled to breakfast, and talked even less than the day before. She ate, but she didn't drink. At her lesson, her professor showed her to a room just up the steps from the bunks. Climbing up the stairs was torture, but again, Paisley composed herself well. After all, she was in no danger of wetting.
The room was one of many. Hers was number 73, the very last one at the end of the hall.
"This is where you can go for privacy," her professor said, opening the door to reveal a chair, a table, and a bookshelf. "You can personalize it however you want. It has a lock, it's soundproof, and this is the one place you're allowed to go at night."
Paisley's ears perked up. If she could leave her bed at night, for any reason, she could have an excuse to use the restroom, right? She realized her legs were shaking, and she tensed her lower half to stop them. She also straightened her posture, which had faltered, and ignored the searing bladder pain that standing up straight was causing her.
"You have this place so you can practice your power," she explained. "Superpowers are rooted in emotion. It's as personal as personal can be. There's only so much I can teach you in the classroom, the rest you need to unlock yourself. Just be careful with this door, though. Sometimes it sticks."
Paisley strenuously made it through the day, but the poor girl needed to pee so badly she couldn't stand it. Every time something happened that would jar her bladder, she'd gasp or wince and hold back tears. At lunch, she ate but didn't drink, just like breakfast. She denied the invitation to play frisbee and suffered through her school lessons with extreme difficulty. Her handwriting was far worse than usual because her hands were shaking. She felt her skirt digging painfully into her tummy, and her bursting bladder pressing up against her other organs. By the time dinner rolled around, her neglect of any kind of drink was haunting her. On top of her dire and unbearable need to urinate, she was parched. Her throat was dry, and she couldn't get through dinner without anything to drink. She downed two tall glasses of water.
Paisley looked down at her bloated stomach. She looked pregnant. She couldn't stop shaking, so she put both of her hands in between her knees until it was time to go back to the bunks. She waddled agonizingly to her bed. Bending down to change was also torture. She could feel her bladder squishing around like a water balloon inside her when her legs pressed against it. She couldn't stop a couple tears from going down her face, but she wiped them away quickly. The poor, bursting girl crawled into bed, holding back sobs of agony. She ran her fingers over her bloated, overfilled bladder and winced. It was sensitive to the touch. She rolled over on her side, gripping the bedsheet hard and biting into her pillow. Her bladder felt like it was going to tear and spill every drop of urine it was holding. She writhed around in agony, biting hard into her knuckles. Paisley pulled the waistband of her shorts and underwear away from her belly for the small amount of relief it gave. She glanced down past her huge, bulging belly at her pussy, which was locked shut and holding the floodgates at bay. She gripped it in hopes of feeling a little less desperate, but instead felt something different. A shockwave of pleasure spread from between her legs, through her bladder, and then shot through her entire body.
She gasped.
Paisley had never felt it so intensely like that before. She'd masturbated, but it's never been that good. Could it be her need to pee? It still hurt so bad. She wanted nothing more than to empty herself, but she had to try something. Painstakingly, the poor girl crawled out of bed and made her way out of the bunks, hunched over as to not jar her bladder too much.
The patter of her bare feet against the cold ground was reverberating off the walls, but she didn't care. As she left the bunks, she caught sight of one of the professors, the same one who told her off the night before, roaming the halls. The toilet wasn't an option, but it wasn't her destination at the moment. She had both hands caressing her enormous bladder as she went up the stairs. Her tortured tummy felt like it was going to explode with pee. She got to room 73, where she rushed in, shut the door, and collapsed to her knees.
"Ohhh!!!" she moaned, on the verge of sobbing. "Owwwww..." Both of Paisley's shaking hands were clutching the sides of her shorts so hard her knuckles were white. Her screaming bladder pulsed with extraordinary pain. She yanked her cotton shorts and underwear down and laid on the floor. She writhed around in pure desperation, punching the ground and moaning in misery. The searing agony of her dire need was visible in the way her gorged, overstretched bladder bulged out of her stomach. It looked like she'd swallowed a bowling ball. She gripped her crotch again, and felt the same pleasure she did before. She moaned blissfully, her eyes rolling madly in her head, while she felt every fiery nerve that commanded relief suddenly stimulate in a wave of euphoria. Her heart was racing, her chest rising up and down as her fingers worked like magic in between her legs. Her belly pulsed as more liquid piled up behind her overworked sphincter, but she welcomed it. While her right hand continued, she brought her left hand up to her bladder and applied some pressure.
"Huhhn---" she moaned, feeling it push on her other organs. She pushed down harder, and her entire body was rocked with bliss. Waves of sexual energy were sent throughout her entire being, and she came. It was the best orgasm she'd ever had, and it left her laying there, sweating and panting, feeling relief for the first time in days. She hadn't peed though, so her relief was temporary, and her overstretched bladder was soon sending messages to her brain, begging to be emptied, screaming to be drained of the enormous amount of fluid that was pent up inside of her. It was bad, but it wasn't as bad as before. Masturbating had dulled the pain a bit. She went to get up, but her bulge pressed against her thighs.
"Ohhh..." she moaned, dropping to the ground again. It seemed her bladder had filled even more. She laid there for a moment with her hands balled up into fists and her flushed red face contorted in excruciating pain. She rolled over to her side and pushed herself up that way, struggling to stand like a baby calf. She really looked pregnant now. Her pulsing tummy was protruding out of her so much it looked like she might pop. She bent down and pulled on her shorts and underwear, groaning miserably as her enormous belly squished against her legs. Paisley made her way to the door, hunched over and miserable, and tried the knob...
But it didn't open.
"Careful with the lock, sometimes it sticks," were the exact words her professor used. She pulled harder, but it didn't budge. Whimpering and stepping in place, needing to get to the toilet and empty the ocean inside of her. She yanked the door with all her might. It swung open and sent her falling on her butt, jarring her bursting bladder. She bit her lip and scrunched up her face, trying with all her might not to scream in pain. She stood back up shakily and went stiffly down the hall. I have to get to the bathroom, she thought. I can't wait until morning. It hurts so badly. If someone tells me off, I'm not going back to bed. I can't let anyone stop me from peeing...
She turned the corner and almost walked right into someone. It startled her badly, but she didn't spill a drop. It wasn't a teacher, though. It was a girl. The girl who was heating up her coffee the other day with her fingers. She had short black hair and pale skin.
"Uh-- ex-excuse me..." Paisley stuttered, struggling to stand up straight and look normal.
"What are you doing out here?" she asked.
"Uhm... I need to go the bathroom," she replied defensively. Stop talking to me, she thought, please, please stop talking so I can pee...
"Oh yeah?" the girl asked. She touched her hand to Paisley's bladder. She was taken aback by this unexpected and rather bizarre turn of events, but something was welcoming about it. Her hand was warm and her demeanor was inviting. "I have to go, too," she whispered, taking Paisley's own hand and putting it against hers. It was rock-hard, like Paisley's, but not nearly as large. She was surprised that the girl wasn't showing any signs of desperation. Paisley's hand was shaking from her dire need, but the girl's hand was steady and calm. "That's the biggest bulge I've ever seen," she said, "I didn't even know it was possible to get that big." She met eyes with her. "I see you skipping your morning piss every day, and squirming all class long. You like to hold your pee, don't you?"
Paisley didn't know how to respond. The entire situation seemed kind of surreal. "How long have you been holding?"
She decided to just go with it. "T- uh, two days."
Her eyes went huge. "Two days!? That's impossible!"
"M-My power is t-that m-my body can't be d-damaged. I-I've never involuntarily w-wet myself."
"Oh. Only voluntarily, then?" She winked.
"No, no! I don't t-think you underst-stand. I really need to go. I can't take it anymore." She started stepping in place again. The dullness that her orgasm had granted was wearing off.
"You can hold it a little longer, can't you? It would feel so good," she pressed down on Paisley's belly. Pain shot through her abdomen and she pulled away.
"I r-really can't. I don't even d-do this often," she gripped the sides of her shorts, "It hurts so badly, I f-feel like I'm gonna explode."
"So do I!" the girl said, shifting a little. It was the first physical sign she gave that she needed to go. "Look, I'm not trying to pressure you into anything, but I've been holding my pee in just for you. I figured we could fuck around a little bit. I really don't want to go back to sleep while I need to go this bad."
"I'm not-- completely opposed t-to it," Paisley admitted, "but I r-really can't take this anymore. It h-hurts so badly." Both of her hands had found their way to her belly, caressing it as pulsed pulsed and screamed, begging to be emptied. Tears were starting to well up in her eyes.
"She's not going to let you into the bathroom," the girl told her. "Not even I can sneak through. She's always patrolling the halls at night, making sure we don't meet up with any of the boys. Plus, I wouldn't even know how to get past the lock."
"L-lock?"
"Yeah, they lock the bathrooms at night. You didn't know that? They think we're gonna fuck in there or something." The girl bent forward a little bit and pulled on the waistband of her pajama pants. A wave had hit, apparently.
"What am I gonna do?" Paisley moaned, wiping her eyes. "I have to go so bad I feel like I might burst open!"
"I can give you some relief," the girl said, "it would be better than squirming around in bed for the next five hours."
"Five hours! Oh my god..."
"Hey, at least you can't wet yourself! I'm on the verge of leaking here!"
Paisley sighed a shuddery breath. By 'fuck around,' this girl obviously wanted to do something sexual, which she kind of wanted to do, but a realization that she was completely and utterly inexperienced flashed through her mind. She'd kissed one person before; a little red-haired girl. It was the sixth grade. Still, her enormous, rock-hard bladder was begging for relief, and it took priority over her possible embarrassment. The girl was waiting impatiently, tapping her foot and fidgeting ever so slightly.
"You wanna go?" she finally asked. Paisley nodded. "Alright, let's go. Hurry hurry hurry! Which room's yours? Mine wouldn't be a very good spot for this."
She waddled painfully to her room. She entered and immediately collapsed onto the floor, whimpering and caressing her bloated bladder. It hurting so badly. All she wanted to do was empty it, but she'd have to find relief elsewhere. She writhed and squirmed, hitting the ground and biting her knuckles. She saw the girl give herself a quick squeeze. "What are you doing?" she asked, stepping a little in place.
"It hurts," Paisley replied, "it feels like my stomach is gonna tear open!"
The girl smiled and kneeled down, moving her hand over Paisley's screaming bladder. "I'm Vera by the way. I know you're Paisley, I heard you talking to Breanna." The desperate girl nodded, sweat dripping down her face. Vera lifted Paisley's shirt up to reveal her bulge. "Jesus fucking Christ!" she exclaimed, laughing. "You're sure you don't do this often?" She pressed down hard on it. Paisley jumped and yelped.
"No no no no no no, please please please don't do that!" Every nerve in her shaking body was on fire.
"Don't do what?" Vera feigned innocence and slapped Paisley on the belly.
"Owwww, don't, please--"
"Your body can't get damaged, right?"
She nodded. Vera pushed down hard on her bladder. It was enough to make Paisley cry out, tears running down her face. She laid there nearly sobbing for a minute.
"I have a water bottle in my bag," Vera said, "you need me to go get it? You can pee at least a little bit so it's not so bad." She nodded, and Vera leapt up and ran out to get it. She looked down at her overstretched belly. The faint pulsing of the ocean of urine she was holding was sending throbs that she felt through her entire lower half. Vera returned promptly and handed her the bottle. It was much larger than Paisley was expecting.
"I was saving it for myself, but it seems like you need it more," she said, squirming and squeezing herself much more than she was before. "It was full, so I had to drink the water."
Paisley strenuously rose to her feet, hobbled over to the chair, and gingerly sat down. She looked up at Vera with worried eyes.
"You're not gonna be the first one, huh?" she asked, giggling. "Alright, then." Vera pulled down her pants and completely exposed her privates. Paisley's eyes went wide. She gently pulled her shorts down and put the bottle up to her pussy. For the first time in days, she relaxed. Urine immediately burst out of her like a firehose, exploding full force into the bottle. She moaned and let her head drop back, smiling blissfully. The feeling of relief was nearly orgasmic, until Vera shouted.
"Paisley!"
She snapped back into reality and saw the bottle nearly overflowing. She immediately cut off the stream, which proved to be astoundingly painful.
"Ah! Ah! Owwwww... Fuck!!" She squeezed herself hard, not to stop urine from continuing to gush out, but because her urethra was burning like it was on fire. Her bladder was still in an extreme amount of pain, bulging out just a little less than before. She placed the bottle, which was filled to the brim with her hot piss, on the table in front of her. "God, that was torture..." she muttered, bent over and pushing her hands into her groin.
"Torture for me, maybe!" Vera said, twisting like a pretzel. "I had to watch you explode like that. It was kind of crazy to watch your bulge get smaller, though." She bobbed up and down with her hands between her legs. "You sure you're still up to fuck around?"
"Will it make me feel better?"
"It'll be relieving in its own way."
She shook her head and shrugged. "Honestly, I'd do anything to have this hurt less."
Vera didn't waste any time. She came up and kissed her on the lips. Paisley's heart fluttered with excitement, though she was still so filled with liquid that she was shaking like a leaf. Vera started dancing in place desperately and ended up sitting on Paisley's leg, scooting back and forth and tapping her crotch, still kissing her. She leaned in and accidentally drove her knee directly into Paisley's bladder.
"Ohhh..." she moaned, lurching forward.
"Oh shit!" Vera laughed, still squirming heavily. "I didn't mean to do that. Fuck! Okay, I'm not trying to rush or anything, but we need to get going before I pee myself, okay?" She pulled Paisley's chin up and kissed her again, scooting back and forth even faster. They made out for a few minutes, as Vera's desperate potty dance got more and more animated. Paisley's hand was constantly gripping the side of the chair, and she continued to kiss Vera through the pulsing, unbearable pain in her tummy. She felt a dampness on her leg where Vera was scooting, and she knew she was starting to lose control. Neither of them were wearing any pants to absorb anything. After a couple more minutes, Vera pulled away.
"If I can be honest, I've never done this before and I don't know where to start. I just know when I masturbate, I stop having to pee so badly and it feels really good. We need to get going 'cause I'm starting to pee." She pointed to a shiny patch on Paisley's pale thigh...
