Bombality

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.
