“How did this even happen ?” Princess Daisy groaned, sitting next to her two partners in a vast cage suspended over a pit of lava. 

“It’s all my fault…” Princess Peach muttered beside her, her head in her hands, seemingly deeply disheartened. “I should have known better than to let Bowser find out about us…” 

Princess Rosalina looked at her in confusion. 

“Did he kidnap us because of our relationship? I wasn’t aware that was the cause.” 

“I told him we were dating, and he seemed to take it well…at first.” Peach sighed. “He asked if he could join our polycule. I said I wasn’t interested, but he could always ask you two, and well…” She gestured around miserably. “Here we are.” 

Daisy seemed to quickly perk up despite the grim circumstance the three had found themselves in. 

“Well hey, at least we probably won’t be here for too long. Mario’s sure to show up and get us out any minute now!” 

“I sure hope so…” Peach murmured as she shifted from foot to foot, crossing her legs underneath the fabric of her opulent pink dress. In truth, she had more reason to worry about being trapped here than just the danger her situation posed. She hadn’t gotten a chance to pee before being whisked away into the bowels of Bowser’s Castle, and her bladder had been continuously filling up since, what had once been a faint, easily ignorable urge now a persistent and uncomfortable series of pangs. She knew Daisy was right, it probably wouldn’t be long until Mario showed up and they could go free. But how long exactly would that take? She didn’t want to think about it, but keeping her dress and panties dry wasn’t entirely guaranteed…

Little did she know, her two partners were in a very similar predicament, though they much like her, they did their best not to let it show. Daisy could feel the piss inside of her sloshing around, angry at being confined. While she was just as full as Peach, she had far less experience holding it in when she needed to go, often just using the restroom whenever one was nearby and popping a squat somewhere private whenever one wasn’t. Now unable to do either, she found herself squirming uncomfortably, her legs crossed just as tightly beneath her own golden dress. The color was unfortunate, a reminder of the lake of liquid gold she struggled to hold within her. 

Rosalina was probably the best off of the bunch, but she was by no means having a good time either. Her bladder was significantly larger than the others, but she also lacked experiencing holding it, though not nearly as much as Daisy. Her urge could have been a lot worse all things considered, she was still a good ways away from being desperate, but it still irked her immensely. The constant tingling and pressure in her abdomen left her frustrated (one might even say pissed off, if one was rather fond of puns). She paced up and down the inside of the cage as much as she could in its cramped conditions, her legs staying close together. She couldn’t help but wonder if this was how her urine felt, trapped within a cage of flesh rather than one of metal. 

Several hours passed, and there was still not even the slightest sign of Mario. All three princesses' desperation had grown greatly, and at this point, it was impossible for the three not to notice each other’s predicaments, as engrossed in their own as they might have been. Peach had one hand firmly jammed into her privates, Daisy had two and was panting heavily as she bounced rapidly from foot to foot, and Rosalina was squirming constantly and occasionally pausing to grab herself for a few moments before retracting her hand once more. 

“So, ah…” Rosalina spoke up tentatively. “I guess we’re all bursting, then?” 

“Bursting’s an understatement.” Daisy grunted as she continued furiously potty dancing. “I feel like I’m about to explode!” 

“I’m…certainly not feeling great right now…” Peach muttered as she squirmed. “But I can…still…hold it…” 

Daisy snorted. 

“I doubt that,” She commented. “You hardly look better off than me!” 

Rosalina looked deeply concerned, eyes darting about in search of anything that could serve as a way for the ladies to relieve themselves. 

“There has to be some way to resolve this…please…” She tried to keep her tone even, but it was hard to conceal just how desperate she truly was. 

Daisy hissed through her teeth as she felt a strong leak escape into her panties. 

“You know what, screw it!” She growled. “I’m gonna piss myself in a few seconds anyway, might as well get this out of the way now!” 

As the other women watched on in total confusion and bewilderment, she pulled her dress aside and yanked her panties down, squatting over a small grate in the center of the cage floor and pissing without hesitation. Her stream was quite strong, and while most of it went through the grate, a lot of it still ended up splashing against the floor. The sound was a deafening hiss as her pee evaporated the moment it hit the lava below, only overpowered by the noises Daisy herself made upon finally being granted her relief. 

“Oh fuuuuuuuuuck yes…” She groaned, tilting her head back as she relished the sensations rushing through her. “That’s what I’m talking about…!” 

The other princesses present didn’t share those feelings, however. The sound of Daisy getting her much needed relief sent both women’s bladders into overdrive, Peach performing a truly frantic potty dance as she struggled desperately to hold on for even a few more seconds in the face of this overwhelming reminder of just how much she was holding back. Rosalina wasn’t faring much better, finally having to thrust her hands into her crotch like the others as she grimaced in pain, her bladder feeling like it was being crushed by a gargantuan fist. 

“Can you…try and hurry it up, please?” She asked, unable to stop her sheer frustration from coming through in her voice. “The two of us need to go too!” 

“I’m…working on it…” Daisy sighed, her cheeks red from ecstasy. “ Pheeew, I really needed that…” 

“Don’t rub it in!” Peach hissed angrily, followed by a whimper as a strong spurt escaped into her pink panties. “Ohhh, I need to pee so badly…” 

“Now that I can agree with.” Rosalina said with a wince, managing a strained smile. “Please, Daisy, hurry up…” 

Though it felt to the two bursting ladies like relief would never come, just as they were truly beginning to hit their limits, Daisy’s stream finally tapered off and came to an end. With a little laugh, she pulled her panties back up and let her dress fall back down, beaming in the afterglow of her monumental piss. 

“Man, did that feel good!” She chuckled, stepping aside. “Well, it’s all yours, babes!” 

Rosalina didn’t pause for even a moment, dashing forwards and doing much as Daisy had done, pushing her dress aside and this time not even bothering to pull down her panties, pissing regardless of the starry, partially transparent blue cloth obstruction. It did little to deter her stream, the flow of piss coming out just as strong as Daisy’s, and a good bit clearer. She closed her eyes and let out a comparatively much more reserved sigh, though still significantly louder than any noise she normally made. 

“ Haaaahhhhhh…ohhhhhh…” 

Meanwhile, Peach’s bladder had reached critical mass. She was well and truly at her limit, her incredibly overfull water balloon of an organ bulging out visibly against her dress and finally out of room to expand. No matter how hard she clenched her abdominal muscles, leaks still kept coming out of her every few seconds, enough that a stain was beginning to be visible on the front of her outfit. She could feel a powerful wave starting to slowly surge towards her exit, but despite part of her knowing that this had to be the end, she still fought to hold on. Somehow, she managed to keep the bulk of her urine inside her until Rosalina finished her piss, one which was even longer than Daisy’s, though Peach was doubled over and holding back tears by the end of it. 

“Come on, darling!” Rosalina called out to her as she stepped away from the grate. “You can still make it!” 

But Peach, despite everything, refused. 

“I…can’t…pee…like that…” She groaned. “I’m a princess…I…have to….hold-” 

But that was as far as she made it before her floodgates definitively crumbled. It all came surging out of her in one massive flood, rapidly soaking and staining everything at and below her dress’s waistline a dark, wet black. A puddle soon began to form at her feet, growing quickly, though it started to drain as soon as it reached the grate in the center of the cage. Despite herself, she couldn’t help but let out a moan of her own, all control lost at this point. Still, it was just as much one of despair as it was one of relief. 

“Ohhhhhhhhh… ohhhhhhhhh no…”

It took her a little less time than Daisy to finally empty completely, on her knees by the time she was done. Tears ran down her cheeks. 

“Hey, hey, it’s alright, babe!” Daisy cried, rushing to her side. “It’s okay, accidents happen! I probably would have pissed myself too if I’d been a bit slower!” 

“But-” 

“Please, rest assured we don’t hold anything against you.” Rosalina said with a warm, compassionate expression. “Besides, the problem is easily resolved.” 

She waved her wand, and in an instant, all the stains on Peach’s dress instantly disappeared. The pink princess paused, gazing in wonder and amazement. 

“We’ll still love you, babe. Even if you piss all over your dress, that doesn’t matter. You’re still you. ” Daisy said with confidence. “So chin up, okay? You’re the strongest lady I know. The moment we get out of here, I’m gonna kick Bowser’s ass for doing this to you!” 

Despite it all, Peach couldn’t help but smile. Maybe this day was going to be alright after all…
