Can a small dragon's bladder of steel best that of Starlight Glimmer? Omorashi

Spike wants to prove to Starlight that he can hold his pee longer than her. Well, she doesn't care for a competition, but Spike is gonna make it one anyway.

Contains: Omorashi (holding pee, desperation), urination, masturbation, and I guess Spike is underage. But he's not a horse so it's not foalcon. Hatchlingcon, maybe?

The cover art was made by Frist, used with permission. This story was written for him and a couple of other friends, so I hope y'all enjoy. This isn't my fetish, but I do like writing things like this for friends and stuff.

Urine for a challenge.

Starlight, easy steps clacking against crystal floor, hummed a song from her old village that would have been an unwelcome reminder of darker days had the villagers not forgiven her and kept the song alive as part of their history. A comfortable smile adorned her face as it gently bobbed side to side.

"In our town, in our town, da da da da dah..." she sang under her breath.

Movement ahead caught her attention as Spike came around a corner, walking toward her. She waved at him. He waved back with a friendly smile, as always.

"Hey there, Starlight," he said as he approached.

"Hi, Spike."

Just before they passed each other, both turned toward the same door.

The bathroom door.

"Oh," Starlight said, stopping. She waved a hoof. "Go ahead, I'm not in a hurry."

"No, no, no. You got here first. I can wait," Spike offered.

"We got here at the same time," she said, resisting rolling her eyes. "Anyway, I can hold it longer than you, so you should go first."

The dragon's head tilted slightly, as if unconvinced he had heard correctly. "What, now? You can hold it longer than me? I don't know if you know this, but I had to live with Twilight in the library for years. That pony can take hours to do her mane, when she's trying to look nice for Celestia."

"Pfffhaw, that's nothing. Back at my village, do you know how many outhouses we had? Four. For more than a hundred ponies! The only time there wasn't a line was in the middle of the night, and even that was no guarantee."

"Oh, you're on."

"On?" Starlight laughed. "What do you mean, 'on'?"

"I can wait here all day." Spike crossed his arms and adopted a smug grin.

"Spike, this isn't a competition."

"Isn't it, Glimmer? Isn't it?"

Starlight rolled her eyes. "No. It isn't," she said, and promptly went into the bathroom.

"Ha! I win!" Spike cried.

"Yep, you sure do," came the dismissive reply, muffled through the door.

Spike narrowed his eyes. She couldn't get away with this. He had to show her.

After a lifetime of serving as Twilight's assistant, he had a very good mind for taking mental notes. And, take one he did.

It took three months to find the perfect opportunity.

Twilight and her friends had to go to Canterlot for several days. Trixie was way off in Vanhoover. The School of Friendship was on break. The castle was empty except for Spike and Starlight.

He made sure to spend as much time with her as possible. If she was suspicious of his sudden desire to help her with literally everything, she didn't show it. And eventually, as planned, she had to use the bathroom. Just before lunch (he had noticed this was a common time for her), she excused herself. He followed at a distance just to be sure, then waited patiently outside the restroom.

After a flush and quick hoof wash, she came out. "Oh, hey, Spike," she said.

"Hey. Just gotta go, too," he replied. "You know. To the bathroom. Like I do every day."

"Uh huh..." She gave him a quirked eyebrow and walked away.

Whew, Spike thought. He went in and emptied his bladder, then washed his claws.

"And now, the waiting game," he said to himself.

He turned off the water and smiled sinisterly into the mirror as he blew fire onto his claws to dry them.

Under the sink, there was a timer hidden behind the cleaning supplies. He retrieved it and pressed a button on top that activated it. Glowing purple numbers began counting up. The timer was quickly placed back into hiding.

Oh, yes. Starlight was going down.

"Here ya go, Starlight," Spike said, offering her a glass of water.

"Thanks, Spike." She was sitting at the desk in her room, writing in the light of the late afternoon sun that illuminated a large, neat rectangle. Taking the cup with her magic, she brought it to her lips. Spike, behind her and out of her field of vision, did the same. She stopped. He stopped. She set the cup down, and he did the same.

Just gotta drink exactly as much as she does, he thought. Then I can be sure.

After erasing and rewriting a few words, she idly took a sip, and Spike nearly dropped his cup in his rush to follow suit.

She squirmed in her seat, and he tensed up, like a predator ready to pounce. It was a false alarm, though; she was just getting comfortable. Regardless, it spooked him too much to let it go, and he decided to move to the next phase of his plan.

"Hey, Starlight?" Spike said. "I'm gonna go take a bubble bath."

She didn't look away from her work. "Yeah, okay, have fun."

"You don't have to use the bathroom first, do you?"

There was a slight pause, just enough to tell Spike that his timing was perfect. "Nah, I can wait."

He nearly cackled, but disguised it as a small cough. Oh, yes, he thought, so can I.

Bringing the glass of water with, he hurried to the bathroom, went in, and locked the door. He breathed a sigh of relief.

"Okay," he said to himself, "now to wait."

Beneath the sink, he found his timer, still keeping accurate track of the time, and placed it on the counter where he could easily watch it. It had been just over six hours.

Well, there was no sense in wasting the perfect chance to take a nice bubble bath. After all, he had told Starlight that was what he was doing.

So, he ran the water, as hot as possible, until the crystal tub was half full. He squeezed in a liberal amount of bubble bath soap, and soon, the water was as warm and foamy as hot cocoa with frothy milk.

"Ahhhh," he sighed as he slid into the bubbly tub. It was no lava bath, but hot water also felt good against his scales, and the bubbles tickled his face delightfully.

As he made himself comfortable, he decided that this was going to be the easiest competition of his life.

Starlight pondered over her paper. She was writing out daily plans for the next month. As organized as she was, planning a full month ahead was definitely a habit she had picked up from Twilight.

"Mm, then buy a new box of tissue paper, water Phyllis, and wipe down my night stand on the eighteenth," she mumbled as she scribbled notes with a pencil gripped in her magic.

As she stopped to think of what else she might need to do that day, the lapse in focus caused a mild discomfort to catch her attention. It had been maybe an hour since Spike had gone to take his bath, but he hadn't returned. It was still too early for his bed time, so maybe he found something else to do. She set her pencil down and stood up, stretching a bit as she did, before walking to the castle's bathroom.

Huh? she thought as she noticed the closed doors. Oh no, is he still in there? She knew that he could take painfully long bubble baths. Had he said bubble bath, or was it a regular one? She wasn't sure now. She knocked on the door. "Spike?" she called.

"Yeah?" Spike said, a small amount of splashing confirming her fear.

"Oh, just making sure you're okay in there."

"Yep, I'm doing just fine."

"Let me know when you're done, okay?"

"Can do!"

Starlight sighed. Well, she had plenty to do in the mean time. She could wait.

Spike watched the last of the water drain from the tub, less than lukewarm and murky from use. This wasn't the first time he had drained the water, either. His bubble bath soap was nearly empty, but once the water was gone, he squeezed the last of it into the tub and turned on the hot water as he stuck the plug back in.

There was definitely some pressure building up inside him, and it was noticeable, but he had endured far worse. The glowing timer was a constant reminder if it, though. He had to outlast her. His pride was on the line!

Ten hours since the last time he'd gone. About four of those hours were spent in the tub, and he was always glad that he didn't wrinkle like ponies. Ten hours wasn't bad, but in keeping up with Starlight's water drinking, he felt that the urge to pee would hit sooner rather than later. For now, though, it was easy enough to forget it as he turned off the water and sank once more into bubbly heaven.

Starlight Glimmer shifted in her seat. Left, then right, then left again. Each movement kept her bloated bladder's protests at bay. She'd started squirming some time ago, and had only gotten progressively squirmier since. Spike was still taking his bubble bath, having been in there for more than six hours now. It was past his normal bed time, but last time she had checked on him, he simply said he was almost done.

Yeah, almost done, she thought. I'm almost done with you and your long baths.

Sitting was getting a bit painful, as her bladder was causing cramps with her insides pressing against it. So, she eventually stopped wiggling to stand up, immediately alleviating some of the discomfort.

Okay, this is getting ridiculous, she decided. He was gonna come out whether he liked it or not.

The walk to the bathroom was fine, though she had to squeeze her hind legs together a bit, making her gait just a little stiff and awkward. She knocked on the door once more, as she had done several times over the course of the night.

"Spike," she said, "it's well past your bed time. Time to come out."

"Almost done!" he cried.

"There's no 'almost' about it. You're done, and I'm putting my hoof down here. Come out, now." Sometimes she had to be firm.

"I will in a minute!"

Starlight growled. Her horn glowed as she mentally reached for the door's lock... only to be stopped by a powerful protection spell. "What?" she said to herself, confused. "Spike, open the door!" Had he really used a lock protection gem on the bathroom door? That was usually reserved for the front door when nopony would be home for days.

"Wait your turn, sheesh," he said.

She could hardly believe what she was hearing. Spike had never been so insolent over a bath before. Horn aglow once more, she tried to open the door, knowing it was pointless, but doing it anyway for effect. "Spike, come out right now or I swear to Celestia..."

There was silence, and for a moment, she expected the door to open. Listening closely, she noticed there wasn't even any splashing anymore. So, that was good, right? He was actually almost done.

So, she waited. Patiently.

Angrily, but patiently.

Spike swallowed a lump in his throat. Pissing off Starlight Glimmer was one of the scariest things he'd ever done, and now her silence was keeping him guessing. Did she leave? Was she going to blast a giant hole in the door? Had she possibly... lost?

The worry, as bad as it was, actually helped a little to keep his mind off of his urgent need to urinate. But, soon enough, he was pressing his legs together and writhing, just as he had been minutes ago, before she'd shown up.

The baths were done. The water was too relaxing, and did not help to hold it in. He'd begun pacing and reading the back of a shampoo bottle about a half an hour ago. Time seemed to crawl, but he was determined to win, no matter what.

"Spike," Starlight said through the door. It was lower, less angry. A little desperate? He hoped so. "I didn't want to say it before, but I really need to use the bathroom. I'm serious. Please hurry up."

Yes! he thought. So close, now.

He shivered, overcome with excitement and still-building pressure. The discomfort was all about to pay off. "It won't be long," he said, smirking at his own clever half-truth.

He pressed one claw against his crotch as he squirmed. He hadn't ever felt quite so desperate, despite his claims to Starlight months before. Sure, Twilight could take a long time in the bathroom, but she did always step out to let him in if he knocked. Still, the looming promise of sweet victory kept him dancing in place with confidence.

"Okay," Starlight muttered to herself. "Just focus. You can do this. He has to come out soon."

She was mildly surprised he wasn't starving in there, with how often he'd snack. He had to be almost done. Had to be. If he was out of the bath, what else could he be doing?

"In our town, in our town, we work as a team..." she sang to herself, dancing a little as she pressed her hind legs together rhythmically. As full as she felt, she knew she could keep it in for a bit longer. Or, if she had to, she could try to go outside and find a discreet location to do it. Maybe behind Trixie's wagon... no, wait, Trixie was out of town. There were some bushes just outside, but she'd seen foals playing in those bushes, and making that unsanitary would just be uncool. The more she thought about it, the more she realized she needed the bathroom. It was far too late to go knocking on doors. Surely, Spike would be out any second.

Any second...

Come on, Spike...

It hurt. Spike's bladder was so full that it actually hurt. He danced and pressed and whimpered and panted, desperate to win. He knew she was outside still, as he had heard her singing, and could hear her hoofsteps occasionally, hard clacks against the crystal floor. He'd surely know if she were to lose it.

He reached two claws into his sheath to grab the end of his penis, pinching it. It didn't help much. Options were running out. His muscles had been clenched so long that they were getting tired, and when they tried to relax, it shocked him into redoubling his efforts. Once, a few droplets even leaked out, but he didn't consider that a loss, as they didn't ever make it out of his sheath.

"Spike, please," Starlight pleaded through the door. "Just let me in. I won't look, I just really, really need to go. I promise I won't be mad if you let me in now."

So close. He was so close. He could almost feel her giving in, her dam bursting, spilling her golden fluid onto the floor. The burning shame, her pained grimace, her small whimper of disappointment, and her blush. Warm failure splish-splashing against purple crystal, there for anyone to see...

Spike, still pinching his tip, noticed it had extended out, growing hard between his claws. He didn't really know why, though. That mostly happened in the mornings and when he thought of Rarity.

His panting grew stronger, more ragged, as images of Starlight losing control filled his mind. It wasn't just winning that he was thinking about, he realized. For some odd reason, he loved the thought of her just... peeing on the floor. Holding it for so long just to end in shame.

He wanted that. He wanted her to hold it until she couldn't anymore. Until something like peeing on the floor was preferable to holding any longer. The idea of her losing it, relaxing her muscles, and just opening the floodgates, was sharp in his mind's eye. Yes, he thought, pee on the floor, Starlight.

In his desire to see that, either consciously or subconsciously, he let his muscles relax. A powerful gush of yellow erupted from his mostly-stiff cock, splattering the shiny floor. His breath caught, and he immediately clenched his aching muscles, bringing the flow to a dripping trickle that rolled down his legs. His pinching claws became wet. No! he thought. He had already lost, but his will to compete wouldn't let him let it go so easily.

His will, however, was no match against momentum, and with a small (but steady) flow still forcing its way out, he gasped and shuddered as the droplets came more quickly, warm on his palm. As his claws loosened their grip, no longer pinching but holding his member steady, the wet droplets coalesced into a solid streak once more, a golden arc sailing through the air before hitting the floor with a soft plish-plish-plish.

"Ahhhnnn," he groaned. The pain receded, the pressure was relieved, and the feeling of release was utterly divine. His shame was buried under pure bliss for several seconds, and time felt as if it had slowed while he watched it happen. There was distance to his thoughts, and even knowing he lost after so much preparation was not important at that moment.

With so much built up, the stream kept coming far longer than normal. Long enough, even, for him to get over his moment of overwhelming pleasantness. When his mind returned from its fog, he was still peeing.

"Oh, jeez," he said, cutting the flow. He waddled to the toilet and finished inside it. Disappointment clouded his mind as all the shame of having lost and made a mess came back to him. "Aww..."

"Spike! Open the door!" Starlight said, sounding as if there was a manticore chasing her. The door rattled as she tried it again.

"Just a minute! For real this time!" he called. He tried to push harder, emptying his aching bladder faster, the toilet bubbling angrily as his urine hit it like a raging waterfall. Then he stopped himself as it tapered to a trickle, still dripping a little, and unrolled a clawful of toilet paper. Rushing, he bent over by his large, wet mess on the floor and wiped it up as quickly as he could. Hoping the pony wouldn't notice the streaks or stray drips, he threw the wad into the toilet and flushed it.

His penis was still hard as a diamond, however. He certainly couldn't walk out looking like that. Thinking quickly, he grabbed a towel and wrapped it around his waist, then ran to the door, his scaly feet slapping the crystal floor. At the door, panting, he unlocked it and reached for the knob. Then stopped. Starlight's voice was audible just on the other side.

"No... I c-can't hold it," Starlight said. She reared up onto her hind legs and weakly banged her forehooves against the door as she leaned desperately against it. It was too late. It was coming. Turning around, she grimaced and blushed, leaning back against the bathroom door. She spread her hind legs to prepare for the inevitable. With a groan of mixed frustration and relief, she finally gave in. Her body quivered. Her pussy convulsed, then relaxed. A small whine of disappointment came just as the strong gush of golden disappointment fell to the floor in front of her.

Her eyes closed. Her head tilted back. She didn't want to look.

"Mmmf, dammit, Spike, you and your seven hour bubble baths. Y-you're cleaning this up after!" she said. Part of her hoped he'd heard her, and would feel ashamed of what he'd done. The other part was ashamed of herself. She was an adult. This shouldn't have happened.

Starlight bit her bottom lip, unable to help but enjoy the release to an extent. The painful bloated feeling, the near-excruciating pressure, and the exhaustion from keeping muscles clenched all slowly melted away as she emptied herself on Twilight's castle floor.

Luckily, being crystal, it'd be fairly easy to clean. For Spike. He was to blame, after all. Twilight would never have to know it even happened.

Actually, with her thoughts on Twilight, Starlight realized that that nerdy pony probably knew of a spell for this kind of thing. Royal Flush's Thirty Useful Bathroom Spells, she imagined. If there was a book like that here, Twilight had surely read it. Not that it mattered presently, with her still leaking a steady stream onto the floor. There was a sizeable puddle there now, enough that more than one towel would be needed. And the mop.

She couldn't wait to make Spike clean it up.

Spike's eyes were wide. His heart pounded. His cock stood up, harder than it had ever been. He could hear Starlight peeing. She'd actually lost it! He'd been so close to winning!

Not that winning mattered so much when he could still clearly hear her trickle falling to the floor. And her groaning. Sweet Celestia, he could almost imagine she was moaning. A needy whimper left his lips, and his claw found itself wrapped around his cock. He wasted no time in pumping it rhythmically, eyes glued to the door, and ears straining to pick up every detail he could. She was right there, just on the other side of the door! Peeing!

"Ah-" Spike said, stopping himself from moaning aloud. He had no idea why this was making him feel this way, but as his mind filled in details his senses couldn't, with the reality of it happening and the fantasy of how he was imagining it happening, he felt the strongest urge he ever had to just stroke his cock. Perhaps as strong as his need to pee was minutes ago. He panted, biting his free hand to stifle his groans.

As Starlight finished, panting loudly and so very close to him, separated by crystal and wood, he couldn't keep it in. Normally, he took a while before he came, but this time his orgasm seemed to strike unexpectedly. He fell back as he felt it coming, and with his claw still flying over his slick shaft, he peaked. Gouts of white dragoncum flew up and landed on his body and the floor in sticky ropes. And even when he would usually be done, more came. He'd never experienced a feeling so powerful, and by the time it tapered off, there was some in his mouth and on his snout, some just below his eye, and a lot more than he thought possible painting his tummy and chest.

He lay there, panting heavily, claw lazily squeezing at his softening length.

To his horror, the door clicked open.

Huh, Starlight thought as she opened the door, not locked anymore?

The scene she stepped into froze her in place. On the floor, Spike was on his back, eyes as wide as a frightened deer. He was covered in his own seed, his dark-pink dragonhood clutched in one claw. Her nostrils flared as she smelled his cum in the air, acrid and fresh.

She narrowed her eyes. "Seriously, Spike? You were in here for that? You can just do that in your own room. Do you have any idea what I went through?"

"No, it's not what it looks like," Spike said.

"Really? Because it looks like you made me piss on the floor just so you could rub one out."

"Um..."

"Ugh. Just clean yourself up and get the mop."

While he cleaned up, he told Starlight the full story. She was pretty mad, but she made him promise to never do it again. And to not tell Twilight. He wasn't always the best at keeping secrets, but when it was his own secret, he could be pretty reliable.

He didn't notice, but she had smirked a few times during his full admission. By the time he was finished, her competitive streak kicked in enough that she actually kind of understood why he'd done it. And if she was honest, it was kind of cute and flattering that he got off so quickly to her... accident. She didn't want to admit these things outright, though. Instead, as he finished up with the mop, she got his attention.

"Hey, Spike," she said. "Thirteen hours with four glasses of water isn't bad. Maybe we should try to beat that some time."

His speechlessness was just what she wanted. She laughed, a calculated laugh that would leave him wondering if she was joking.
