The roar I let out sent the servants all scattering to the corners of the room, as well they should – the wrath of the Koopa King is something that nobody wants to deal with. All the servants but one, the one who had brought me his hair-brained idea: the magikoopa cowering on the floor in front of my throne.

"I have to do WHAT?" I demanded of him, standing up to tower over his prostrate form.

"P-Please, hear me out, Master Bowser!" he begged, "The client – Asteyr – he will pay well. Very well!"

I folded my arms, still looming over him as the other servants poked their heads out from their hiding places. "How well?" I asked, taking a step forward that shook the ground.

"E-Enough to pay off all the damage caused by... the incident." he stammered. "With some left over!"

I couldn't deny that I needed the money. Why is it always MY castle that gets wrecked whenever something happens around here, even when I'm not the cause of it? I couldn't really refuse, but there was no way I could simply admit that out loud.

"Yeah... fine." I grumbled, "It's just for one day. Besides, it's a celebrity appearance at my own park! People will love it. It's a great idea, I'm glad I thought of it."

"Of course, your Spikiness." He answered, getting to his feet. "I'll arrange it right away."

And that's the story – the important bits anyway – of how I ended up waiting at the entrance of Bowser World waiting for some guy named Asteyr to show up. He was paying a lot of money to get to hang out with me; the only catch was that I had to do whatever he said. And I'm the king! I don't take orders from anyone! Just this once, though, I'd have to make an exception.

At least hanging out at my own place had some benefits. I'd be able to fit on the rides, for one thing, unlike all the stupid parks in the Mushroom Kingdom. And the other guests would be looking at me with admiration, instead of running off and shutting the whole place down like the Toads would. Or trying to throw me out for indecency; if I want to strut around my own theme park with my cock out – and I do – then who's going to stop me? Judging by the looks I was getting, and the number pictures people took, I was making the day more exciting anyway.

When Asteyr finally showed up, I was kind of underwhelmed. I expected someone a bit more... impressive. You'd think a guy who can toss that kind of money around would roll up in his own limousine, wearing a fancy suit with a whole honor guard of minions to go with him. Instead, this little grey-furred, pointy-eared guy barely half my height came along in a baggy blue hoodie and equally baggy navy-blue shorts. He was walking in a digitigrade stance, and had a pair of goggles covering glowing blue eyes. I thought he was just another visitor, right up until he came right up to me, hands in his pockets, and met my gaze.

"Who're you?" I growled. "You want an autograph? A selfie with the king?"

"Nice meeting you," he calmly replied, grinning wide, "I'm Asteyr."

Normally I would have bellowed out something like, "YOU'RE the little pipsqueak who's going to be ordering me around?" But I held my tongue; a lot of money was riding on being nice to this guy. I'd never hear the end of it from my minions if I blew it, so instead I did my best to look cool and imposing, leaning on the wall behind me with my arms folded.

"Welcome to Bowser World." I replied to him. He didn't need my introduction, he knew exactly who I was – and besides, who doesn't know of the great King Bowser? Nobody important, that's who. "Do you want the tour, or would you rather check it out yourself?"

"I have my own plans." he answered, taking a moment to look me over. I'm not one to turn down an admirer, so I put my arms behind my head and stood with my legs apart to let him check out my pride and joy. Namely, the thick, flaccid, uncut cock and fat balls that, together, have sired seven or eight kids – maybe more, I don't remember – and the crop of fiery red pubic hair that framed them. He certainly seemed to appreciate the view, but gestured for me to follow him and headed on inside. The staff gave him no trouble; they know that anyone traveling with me is a VIP.

And you know what, it was fun to just take a day off and go to a theme park. No worries, no pesky advisors, no inept minions, and no plumbers. After a quick stop at a concession stand for some drinks, we started off with the simple stuff – the haunted house is pretty popular, but I was the scariest thing in there, and I accidentally sent an entire group running off just by rounding the corner on them.

Then we went to the house of mirrors, which was a blast! The mirrors make you look taller or shorter, thinner or fatter, and let me tell you, I looked great in all of them, flexing my muscles and showing off my bod. And Asteyr seemed to appreciate the view too, checking out both me and the reflections of me. Close to the end, as I was flexing a bicep in front of a mirror, he turned and gave me an order.

"Hey, big guy. Show off that cock some more, would you?"

Paying or not, I'm not going to turn down a request like that from a fan. So, reaching down, I grabbed onto my meat with one big hand – most people need two just to hold the thing – and gave it a little squeeze as I lifted it up, away from the sack resting on my inner thighs. "You're lucky," I told him as I tugged back, sliding the foreskin down until it had completely exposed the fat head of my cock, the bottom of my hand thumping against the bush of red pubic fur at the base. "Most people would give anything for the chance to see this."

He only chuckled in response, but his gaze was firmly on me as he watched my distorted reflection slowly pumping his dick, mimicking my actions as I slid the foreskin back up and over the tip entirely, with a little bit of excess left over. Changing course, I pulled back again and slid my foreskin back down, repeating this a couple of times until I felt him grab my wrist while it was at the bottom.

"That's enough for now," he said slyly, "But leave it back for a bit, would you?"

I didn't expect I'd get to fully rub one out, but still, I got left with a half-hard shaft that bounced as I walked, and at his request, I left the foreskin tugged back and bunched up under the bottom of the head, though it slid back just a little on its own as we walked. If the other visitors weren't getting an eyeful of me before, they sure were now, subjects from all over checking out the king himself and his half-erect dick hanging out for everyone to see. I pretended not to notice them, but it felt great to have so many eyes on me.

But that's when things got a little bit weird, as we made another stop at a concession stand, and Asteyr bought us both drinks even though I didn't ask for one; a small for himself and an extra-large for me. "I don't need it," I answered at first, "I just had one."

"Drink up." he commanded, holding out the cup of lemonade to me, "I insist. See if you can finish before the next ride."

He insisted, huh? That settled that. It's pretty rare that someone insists I drink more, but I figured, why not? We spent a bit of time walking to the log flume, and I made sure to drink down the whole cup before we got there – my staff knew better than to make me wait in line anywhere, after all, so they'd cut me straight to the front of the queue.

I took up an entire row of seats by myself, but at least I could fit in them, with Asteyr taking the seat in front of me. On we went, up the hills and down again, getting splashed by the huge waves of water. The last hill had a camera on it, I knew, so I leaned back in my seat and grabbed my cock again to tug the foreskin fully down all the way with one hand, grinning at the camera and making a peace sign at it with the other. When we got off the ride, a whole crowd was clamoring for copies of the picture.

But then he stopped in at a food stall for drinks, again! Before I could even protest, he shook his head and said again, "I insist." What was he doing? I took the coffee, of course – he was paying the bills for more than just the drink – but I started to worry about what he was up to. Not to mention that the previous drinks were going through me pretty quick, and I could feel my bladder getting full. I'd just have to wait for an opportunity; the great Bowser never admits weakness!

The little guy took out his map and looked it over for a while before leading the way through the crowds, and we drank our coffee along the way. At least he had some good taste; the next stop was the park's main attraction, the Bowser Coaster, and there's something great about riding in a rollercoaster car shaped like your own face. I got the frontmost seat, of course – nobody was going to argue with me! The safety bar that went across my lap only just barely fit someone my size, lightly resting on the scales of my belly, but I'd made sure that when they built this place that I could get on every last ride if I wanted to. What would be the point otherwise?

Going up the big hill at the start was great – I could see the whole park from up there, from the elaborate gates at the entrance to the huge Ferris wheel at the back, but then we went down. The car accelerated to the bottom of the hill where the track leveled out and then started going back up, and the sudden change in direction pressed the lap bar into my belly, right up against my poor bladder! Good thing I was in the front this time – nobody could see me wince – but the ride only got rougher from there. Every time the coaster car suddenly changed direction, the lap bar put more pressure on my gut, making me squirm in my seat. Even worse was when it went through a corkscrew, or a loop, and for several seconds it kept pressing against me, making me press my legs together with a groan. I don't think anyone heard me grunting in discomfort over the sound of the rollercoaster... or at least, I hope not. Then again, when we finally got off, Asteyr had one heck of a grin on his face.

I staggered away from the rollercoaster once we got off, rubbing at my belly where the lap bar had kept pressing on me. Asteyr came on over and waved for me to follow again, and I went after him, grumbling. I was starting to have my regrets about this whole thing, but it would be worth it in the end.

As we made our way through the crowds once again, I thought he was taking me off to another ride – but then he led me to yet another concession stand, and I groaned. There would be nothing for it but to admit to my problem, but I could still stay cool about it.

"Hey, while you're doing that," I said as he fished out his wallet, jerking my thumb over my shoulder, "I'm gonna go take a piss real quick."

"What, already?" he said in response, tilting his head. "I would have thought the great King Bowser himself would be tougher than that. I don't know if I want to hang around someone so... weak." My blood boiled; how dare someone so small and...! No, no, I had to stay cool, despite the fire I felt in my chest. A lot was riding on this.

"Who are you calling weak, you shrimp?" I snarled, realizing afterwards that that might still have been too much, and backpedaled. "I don't have to go that badly. I can easily hold it. I wouldn't be king if I had a weak bladder."

Grinning, he placed his order – a medium iced tea and an extra large – and turned back to me. "Well then, here you go, have another drink." he said, looking up at me, the cocky little critter grinning ear to ear as he looked up with his glowing eyes.

I hesitated, and he noticed; his grin widened as he took the cups of iced tea and shook the extra-large one, the ice cubes rattling around at the top. "Unless you think you can't handle it... you must be getting old if you can't hold a couple of drinks, huh?"

It was hard not to lunge at him then and there – my fists clenched, I bared my teeth, and I felt heat in my throat. But I held it back after a moment and folded my arms. I had an image to keep up! "Fine." I said firmly, "I see how it is." I snatched the extra large cup out of his hand, looming over him as I did. "You think I'm not up to the challenge, huh? Well, the king ALWAYS wins." And with that, I put the straw in my mouth and started guzzling, draining half the cup in one long swig. But he just looked at me with a smirk, and took a drink of his own. He wasn't going to back down that easily.

On we went as before, but now, the gauntlet had been thrown down, and I kept my eyes on him as I sipped mouthful after mouthful while we walked. When I finished my iced tea before he did, I made a show out of taking the paper cup and crushing it between my hands into a flat disc, grinding up the ice cubes inside, before tossing it overhand into the nearest trashcan. But the little pipsqueak was unflappable, and tipped back his head as he drank down the rest of his own, casually holding his arm out and dropping it into the trash with barely a glance.

I almost immediately regretted my bravado. As we started walking again, I could feel my bladder protesting from all the drinks I'd downed. I made sure to keep behind him a few paces so that he couldn't see me wincing, doing my best to turn it into a scowl that made everyone else clear out of my way. He took us at a leisurely pace through the park, as if stalling for time deliberately, knowing that with each passing minute I was getting more desperate.

But then I found out what Asteyr wasn't even leading us to another ride, as we passed more rollercoasters, the go kart track, and the bumper cars with my face painted on them. He was just leading us to yet another drink stall! I inwardly groaned as I saw him walking towards the Starbeans kiosk, but I folded my arms and did my best to look tough. And as it turns out, it's hard to look tough when you're shifting your weight from one foot to the other, keeping your legs pressed tightly together, and tensing your abdominal muscles every so often to make sure you don't piss yourself.

"Having trouble, old man?" he taunted as he came back, holding a cup out to me expectantly.

I took the extra-large cup silently, giving him the meanest look I could, but the goggled little guy shrugged it off. I thought I was intimidating him when I saw him squirm in place, but no; with one hand in his shorts pocket, he was subtly gripping his junk through his shorts. He obviously needed to piss as well, but was pretending he didn't. Well, two can play at that game, so I did my best not to let it show that I was getting close to my breaking point, puffing up my chest and asking, "Where next?"

"We'll take a break." he replied, and motioned for me to follow again as he wandered off. I relaxed a little as soon as he turned around – not too much, though – and walked behind him, my feet stomping loudly on the ground as we went. I was expecting that maybe he was giving in, and was finally going to let us both take a piss.

But no! The little twerp instead took us to one of the garden areas where there were benches big and sturdy enough to support me, and took a seat. Around us were a few shrubs that had been pruned to look like smaller versions of me, but worse than that – fountains! He'd picked a spot right in the middle where we were surrounded by fountains, and as a result, the sound of fountains. The noise of water splashing filled my head and made my need to empty my bladder even worse. I crossed my legs as I sat on the bench, pressing them tightly together, my inner thighs rubbing against my pubic hair, watching Asteyr as he tried to play it cool, but still kept his thighs close to one another.

I couldn't completely hide how desperate I was, staring up at the sky and trying to focus on any other sound than the fountains around me. I gritted my teeth, holding my untouched cup of coffee. How had I let myself get talked into this? The things I do for my kingdom. A spasm ran through me and I couldn't help but let out a small grunt, squirming in my seat and pressing my crossed legs together again.

"Losing it already?" I heard from beside me, "I would have thought the legendary King Bowser would be stronger than that." Taking a sip from his coffee, he exhaled and then added, "Well, I guess it's true what they say, never meet your heroes."

Looking back, I know he was baiting me, that it was a taunt. But I was so desperate to piss and internally frustrated that anyone, let alone this little pipsqueak, would talk to me that way, that I took the bait, turning and looming over him. "You don't know what you're talking about." I growled, "You're just as desperate as I am. You're doing it deliberately! If I didn't-..." I cut myself off before saying anything more, though that was mostly from another pang of discomfort from my over-full bladder making me wince.

Asteyr grinned, giving a tiny little squirm of his own in his seat. "Want to bet?"

"Bet what?" I answered immediately, glad that the conversation was taking my mind off the sounds of the fountains around me.

"I bet you can't hold it longer than me." he said smugly – he really believed it. "But if you do, I'll pay double."

I took a deep breath. I've got to give credit to the guy, he does know how to make a tempting offer. "And if I lose?" I asked, taking a sharp breath from another spasm before quickly adding, "Not that I will, the great Bowser never loses."

"When you lose," he corrected smarmily, "You get to follow my orders for another day."

I thought it over, or at least, I tried to, my thoughts constantly interrupted by the fountains' noise and the growing discomfort in my belly. And to make things worse, he piled on the pressure after a few seconds and another sip of coffee: "Not so sure you'll win? I guess the great Bowser isn't so great after all..."

That did it. I let out a roar and stood up, not caring who heard me as I turned on him. "You're on!" I declared, popping the lid off the coffee cup and tipping my head back to chug the whole thing down in one go, tossing the empty cup over my shoulder, then pointing a clawed finger at him. "Be prepared to pay up."

"Good." he replied with a chuckle, unflappable as ever as he got back up. "I know which ride we're going to next."

At least it meant we weren't around the fountains any more, but I was too far gone to try and hide it as well as I had before. I had to walk with one hand between my legs, holding onto my cock and pressing it against myself. With my larger stance I was able to keep up with him, despite him walking a little quicker, keeping one hand in his shorts and probably holding onto his cock as well as he sipped from his coffee every few steps with the other.

We soon arrived at his destination, and cut to the front of the line for the Ferris wheel. It's pretty great, if I do say so myself, with a huge black and red emblem of my face on a disc at the center of the wheel, each spoke holding a car that I can easily fit into. It towers over everything, even the rollercoasters. The minions staffing it quickly let me in without any questions when I glared at them, and as soon as the next car came along, the pair of Koopas inside of it came out, saw me, stared at my glaring face (and, briefly, at my cock) for a half-second and then ran off out the exit, letting Asteyr and me climb in.

I sat down on one side, which caused the whole car to tilt slightly under my weight. Asteyr took a seat on the opposite side from me, and the staff closed the door, the car lurching slightly a moment later as the wheel started to turn. I had my legs crossed again, with both hands between my legs – I had to hope that Asteyr was a lot better at bluffing about his needs than I was, because he still had a grin on his face and was merely rubbing his legs together. For all I knew he had his eyes screwed up tight behind those goggles of his, but they looked like he was just staring at me, daring me to give in as he drained his coffee cup of its last drop. Like hell I would!

But try as I might, I was starting to lose it, and a low "Urgh..." escaped my lips. As I held onto my cock, I felt a bit of wetness at the tip; I must have lost a little bit of it during one of the last few spasms, so I shifted my hand to cover my cockhead completely just in case I lost a little more. Anything to get an edge on the little gremlin.

The Ferris wheel car creaked a bit as we ascended. Normally it would have been a great view of my park and the rest of my domain around it, but I couldn’t enjoy it when I was trying so hard to hold in my bladder. Asteyr leaned back and looked outside, shifting and squirming in his seat, still grinning – he must have been enjoying the feeling. I could feel another warm dribble down the back of my leg and shifted slightly to make sure it would stay out of his sight as I squeezed my muscles again, delaying the inevitable as long as I could.

The wheel stopped for a moment to let the next set of passengers enter the car behind us, and our car swung a little bit. I had forgotten how long it took to do one whole revolution on this thing, with how big it was – we were going to be stuck inside the car for a long time. Minutes passed as I grunted and squirmed, giving up my attempts to pretend I was fine to instead focus on not losing the bet. My hands kneaded my cock as I kept both hands between my legs, taking heavy breaths, sliding my foreskin back over the tip of my dick. I constantly shifted my weight, moving around in my seat, making the already-tilting car swing just a bit more. I looked outside the window – we were only a quarter of the way around!

Another spasm. "Nngh... I can't..."

"Can't hold it?" Asteyr teased.

"Can't... wait to see you lose." I said, glowering at him, though he didn't seem terribly intimidated. I closed my eyes to shut out Asteyr's grinning face, but I felt a hot splash against my fingers, and squeezed my legs together tighter to stop any more piss from spilling out, keeping my fingers cupped around my junk so he wouldn't notice I had spilled a bit. I just had to hold out a bit longer – he was surely just pretending to be fine, the way he was shifting around told me he was desperate too. More was riding on this than just some money or another day of this, it was my pride and reputation!

We made it a little further around the wheel, the car now higher up than most of the rides in the park. I had never had to piss this badly before – when you're the king, nobody questions it if you whip your cock out and hose down whatever you feel like, after all. I groaned again, louder, as another spasm went through me – and I felt wetness on my fingers and between my legs, making me clench my muscles in reflex. It was just a squirt, surely, I could pretend nothing had happened and hold it in just a bit longer...

"Have to... hold out..." I muttered under my breath, but the little gremlin's ears must have still picked it up because I heard him making an amused noise at my expense. I didn't have the energy to spend coming up with another retort and just held my breath, trying to hold my bladder. I felt another squirt escape me, and tensed, but this one didn't stop - as soon as I relaxed just a tiny bit, the flow picked up again. I pressed my legs together, the heels of my hands brushing my pubes as I held myself tightly, trying to stop it...!

...but my body wouldn't obey me any more, and just like one of my incompetent minions, it gave up. My muscles relaxed against my will, and despite my best efforts to stop it, I felt scalding hot piss spraying onto my hands, soaking my inner thighs and my balls. It dripped down around me onto the seat and the floor, pooling up where the seats and the floor met. I tried my best to keep a straight face and pressed my knees and lower legs together, hoping he couldn't see, and that maybe I could hide it from him. With some of the pressure relieved, I tried to clench my muscles and stop pissing, but it was futile, and I could only slow the flow - it wasn't going to stop. My breaths came a bit more heavily as my desperation faded into relief, but I kept my hands between my legs and tried not to let my relief show on my face.

My piss kept spraying onto the back of my legs, the foreskin making it into a thick, lazy stream, and I kept my feet on the floor so that it wouldn't splash on the metal below. I didn't think about how obvious it must have been, or that I had lost the bet, or that my feet were getting soaked, or what the minions would say when we got off the ride - all I thought about was how good it felt to finally let it all out. By the time my bladder was empty and I was drenched from the calves downward, I was starting to cramp from holding the desperate position with my hands between my legs, but Asteyr hadn't said anything yet, and I tried to come up with a plan. Maybe he'd succumb to his own desperation before he noticed my own leak, and I could at least claim a tie, or convince him he'd lost first.

That hope was dashed when I noticed him staring at the puddle around my feet - though calling it a puddle was an understatement. It looked like someone had dumped an entire bucket of piss onto the floor, and I'd never had any hope of hiding it from him. "Spread your legs," he ordered, leaning forward with another big smirk on his face, "You've lost. Let's see the damage."

Reluctantly, I spread my legs for him and leaned back, putting my hands on the edge of the seat to either side of me. My cock hung down, draped over the front of my balls, a few final droplets splashing in the massive puddle of urine below. There was a lot, at least a gallon - I'm a big guy, after all, and my capacity had been pushed to its absolute limit. After a moment, I reached down with one hand and grabbed my cock, tugging back the foreskin from my tip, and leaned back against the seat.

Then, I tensed my muscles and sprayed out the last of it in a few hard jets, before shaking the tip free of the last few drops, and looked up at Asteyr, trying my best to play it cool.

"There," I said, finally able to focus and get back to my normal self, "I'm such a nice guy, I let you win."

"Uh-huh." he replied, legs rubbing together as he squirmed in his seat. My little show had done a number on him, but he still hadn't pissed himself either. As the Ferris wheel car reached the very top, I looked outside for a moment, taking in the view, but when I looked back I saw Asteyr was sliding his shorts and underpants down to his knees.

"There's one more thing you can do for me before I let you go for today." Asteyr said as he used his thumb to push the lid off his empty coffee cup, letting it fall to the seat next to him.

I didn't like where this was going. "What's that?" I grumbled.

"Let me pour you a drink." was the answer as he spread his legs and shifted to the edge of his seat. Unlike me, he had a sheath above his gray-furred balls, and the tapered tip of his cock was peeking out just a little bit. With his thumb and forefinger, he gripped his sheath and used it to point his cocktip downward, holding the empty coffee cup below and just in front of his junk. He started pissing so fast and so hard, I could tell immediately he'd been incredibly desperate too. Damn! If only I'd held out a little longer...

He opened his lips just a tiny bit as he exhaled slowly, the lights on his goggles going out in what I presumed was a mimicking of him closing his eyes. The stream of his piss blasting into the paper cup poured down into the bottom and rapidly filled it, the faint hissing sound from it filling the interior of the Ferris wheel car, as we went past the top of the wheel and started to descend. He glanced down at the cup as it filled up with his urine, making a splashing sound as he pissed into the rising fluid, until it was almost completely full.

He held up the cup, clenching his muscles and squeezing his legs together to cut off his stream. "Here you go," he said as he held out the cup towards me, his other hand pushing his dick back underneath the waistband of his pants. "Fresh and hot. Drink up." 

I very nearly smacked the cup out of his hand – imagine asking me, King Bowser, to drink down a cup of piss? He undoubtedly noticed my expression change, as he soon added, "Unless you don't want my money after all..." with a sly grin. He was squirming, pressing his legs together, seeming to have some trouble holding his half-finished stream in.

I closed my eyes and took a deep breath, before opening them again and taking the cup. The great Bowser keeps his word, especially when money is on the line. The paper cup was warm to the touch from the fresh piss inside of it, and I steeled myself; it would be better to do it quickly and get it over with.

Raising the cup to my lips, I tipped back my head and started pouring it in, determined to chug it down as quickly as possible. The hot liquid hit my tongue with a bitter, salty taste, and I closed my eyes tightly, swallowing down the mouthful of it before I lowered the cup and shook my head. I looked at Asteyr, and saw that he hadn't been able to hold out in the end; there was a growing damp spot on the front of his pants. As I watched, he stopped fighting it and just spread his legs as the dampness spread, enjoying his little accident, still smug enough to keep grinning at me. "Surely this is nothing for you," he commented, "I'd hate to find out that King Bowser couldn't handle one little drink."

A deep growl escaped my throat, but I couldn't resist rising to the challenge, even if it was clearly a provocation. I put that cup back to my lips, and started drinking again. One quick swallow, to get past the initial shock of the taste, then the rest of it – one gulp at a time after another, chugging down the salty contents of the cup. When the last of it disappeared down my throat, I turned the cup upside down in front of him and fixed him with a hard glare to make my point before crushing it in my palm and dropping it on the piss-covered floor.

"Not bad, not bad!" he remarked, swinging his lower legs back and forth, not even trying to hide the wet stain on the front of his pants. We spent the rest of the trip in the Ferris wheel down in silence, but at least I was finally able to look out the sides and enjoy the view. When we got to the bottom and the staff opened the door, a bunch of my piss spilled out from the car onto the ground, and I stomped past them, leaving big wet footprints on the ground in my wake as Asteyr came along after me.

Tomorrow was going to be a long day...
