In the Dark Lands resides the ruler of the Koopa Empire, Bowser. Whenever he's not taking over the rest of the Mushroom Kingdom, making a Galaxy or... whatever inane plan he has this week, he's usually doing his royal duties and well... they were boring. The many downsides of being a king.
Treaties, supplies that needed to be approved, relations with other kingdoms, taxes and etc. Yes, Bowser hated this part. But it was necessary. However, he has received news of a royal of Nimbus Land requesting an audience. That was weird. Why Nimbus Land of all kingdoms?
Was there anyone even worth talking to besides some stuffy nobles? He tried to wrack his brain, but it's been many years. Oh, well. Whatever. He'll just get it over with and carry on. He has other plans to do.
Without thinking it twice, he approved of the summons and waited for the moment they would arrive for some treaty, peace offering or whatever. He didn't care.
Some time has passed and yet another failure of his plan. Surprise, surprise. Mario and his Green Stache had won. AGAIN. He really should be used to this by now. But maybe some relaxation would be in order.
Bowser was alone in his throne room when he hears a knock at the door and groans. He sees his advisor and caretaker, Kamek.
"What is it, old man?" He growled out, not in the mood of any chaos going on right now.
"Well, Your Grouchiness, it's about the Nimbus representative? He's here." The old magikoopa says. Bowser blinks for a moment. But he then remembers, putting a claw over his face and groans some more.
"Oh yeah. That. Yeah, yeah. Send'em." He says, really wanting to get this over with. Without another word, Kamek departed as the doors opened and then closed, hearing footsteps approaching his throne.
Bowser looked down at whomever approached him. It was a small cloud-esque figure with indigo-colored hair, a white body, a purple cape, and he was wearing some pants with white and blue stripes. It seemed like forever until they spoke. "H-Hello, Sir Bowser." They greeted nervously as they bowed. Judging by the voice, they were, in fact, a male.
Although, come to think of it, had Bowser met him before? He'd been on this throne for so long, he couldn't remember EVERY single person he'd met. Realizing that he had taken too long to respond, Bowser replied. "Hey." He said. "And you are… Who, exactly?"
The male looked shocked as if Bowser had forgotten him. Whoever he was, at least. "Bowser, it's me; Mallow!" He replied.
…Mallow? As in that cloud friend of Mario? The one he tolerated on that stupid adventure to stop the Smithy Gang? So many questions were soaring through the Koopa King's mind. The biggest one being the one he asked first. "How did a shrimp like you get to be the rep of Nimbus Land?"
"it was a pretty close election, but after hearing about how we all saved the world together, everyone thought I'd be perfect for the job! Besides, I'm a prince, after all." He explained. "So, what about you? How have you been holding up?"
Bowser grumbled. "I'd rather not talk about that…" He said flatly. "Anyway, we should get right to it: Why are you even here?"
Sensing that the Koopa King was in a bad mood, Mallow got straight to the point. He knows how Bowser operated during that whole thing.
"R-right! Well, uhm... I was hoping we could, y'know... come to a negotiation?" Mallow says, gathering his thoughts together.
Bowser raised an eyebrow at that. What could that cloud kingdom offer him? He was Bowser! Fierce, strong, powerful and super awesome!
"What kind of negotiation, fluffball?" Bowser says to him.
"Well, I mean... Some supplies and such and maybe... uh... a bit of an alliance? In case you or our kingdom need anything." The nimbus boy replies.
He notices. Although he carries himself well, especially his new position. Bowser could tell, the brat was nervous. But he's heard this song and dance before.
"So, basically, we become 'friends' and there won't be some shit later. Right?" Bowser says, complete with air quotes on the friends part.
"Uh… Y-Yeeees…?” Mallow replied nervously.
Bowser rolled his eyes. Figures someone puny like him goes to the biggest guy there is. "Forget it, Mallow." He said. "The Koopa Army is a one-kingdom operation."
Mallow sighed. He knew it was useless to try and argue with someone as tough as Bowser. "I-I see… That's perfectly fine, Daddy."
…Hold up, what did he say?
"Daddy?" Bowser questioned.
Immediately Mallow began panicking. Did he really just say that out loud!? "U-Uh, I mean your royal evilness!" He blurted out. Bowser raised an eyebrow. Obviously not falling for any excuses Mallow came up with.
"Oh, really? I heard you say it, Mallow." The Koopa King taunted.
Mallow began sweating nervously. Should he even tell him the truth? What if the rest of Nimbus Land found out? Would he be demoted? Imprisoned? Something worse?! Mallow began backing away, but this made Bowser furious. "Don't even think about it! I demand an explanation!"
Damn. He read him like a book. "Alright, alright!" Mallow exclaimed. Having little choice to come clean. "I… Kinda find you… Hot! There, I said it! Just please, PLEASE, don't tell anyone about this!"
Tears were flowing down the cloud prince's cheeks as he waiting for Bowser's response. Bowser, meanwhile, was totally stunned at this. Did he… Did he really hear all that? From Mallow of all people? Bowser sighed and spoke. "No-one's gonna find out about this, Mallow." He said. "In fact, I have a bit of a negotiation of my own~"
Mallow tried to calm himself down, wiping away his tears as he stared at the Koopa King with curiosity.

"Wh-what kind of negotiation? Y-you just said-" Mallow stuttered out before he was interrupted.
"I know what I said! But maybe you can change my mind if you agree to a couple of terms." Bowser says, an idea forming into his head after hearing the royal's slip.
"A-as long as nobody from Nimbus Land finds out. Especially my parents. I'll do anything! I... I really want this to go well." The poor kid felt so damn stupid for blurting out one of his deepest secrets. if anyone else were here, he'd never live it down.
"Relax, shortstack. Nobody will know. But lets discuss things elsewhere. The throne is too stuffy. Follow me." Bowser ordered and Mallow closely followed behind, trying to gather his thoughts again.
'I can't believe I let that slip! What if... what if this is a trick and he'll hurt me? No, no. He's had plenty of times, even back then! But he didn't. So... what's gonna happen to me?' Mallow thought to himself, placing his hands on his chest, feeling his beating heart.
Another thought occurred to him as well, he never truly explored Bowser's castle all that well. So everything was new to him. He felt so out of place.
Bowser led Mallow to another room. This one being Bowser's personal chambers. "Wh-What're we doing here?" Mallow asked nervously.
"To negotiate." Replied Bowser. "Now then, you don't want your little secret to get out, right?"
Mallow nodded. Making Bowser grin. "Then you're gonna do exactly as I say." He continued. "First and foremost, get undressed."
Mallow blushed as red as a tomato. "E-Eh?! You want me to…? In my-?" He stuttered. Bowser cut him off there.
"Lose the clothes, I said." He stated. Growing slightly impatient.
Having little choices left, Mallow began stripping down in front of Bowser. First the cape, then the pants, and after a bit of hesitation, his underwear came off, too. Bowser was pretty impressed at Mallow. For a male, he had a pretty feminine figure~
"Th-There." Said Mallow. "Is that all?"
Bowser shook his head. "Far from it. We're just getting started~" He said. Mallow exhaled nervously. What else did Bowser have planned for him? His question was soon answered by Bowser revealing his cock. Mallow gawked at its size. It was huge! Was he seriously gonna…?
Mallow's thoughts were cut off by Bowser grabbing the back of his head and lowering him to face his dick. "Get to it." He said. "Please your 'Daddy', heheh~"
Mallow was shaking. For quite some time after their adventure, he dreamed of doing this to Bowser. But actually having it happen to him? He wasn't all that sure. Still, his secret could prove fatal, so he took the tip of Bowser's penis into his mouth. Making the Koopa King groan. "Mmf! Such a good cocksucker~"
Mallow blushes at those words, his eyes looked elsewhere as he tried his best to please Bowser. Using his tongue and licking the tip.
"I-it's so huge! Th-this would tear me apart! B-but if I don't do this...! I have to at least try!' Mallow thought with nervousness. He could hear the giant Koopa growl with pleasure, as he watched the nimbus licking his cock.
"C'mon cloud boy! You can do better than that! Put some more effort into it!" He teases Mallow, making the kneeling ruler blush some more.
"Pfha... I-I'm trying, Mr. Bowser Sir...! I-it's just... s-so big...!" Mallow says as he stares at the grinning Koopa King.
"So what? I'll make it fit one way or another! Now keep sucking Daddy's cock, like a good whore~" Bowser ordered, making Mallow shudder and didn't want to annoy or anger Bowser any further.
'For Nimbus Land... for Nimbus Land...!' He repeated the mantra in his head over and over again as he resumed pleasing the tip.
Suddenly, Mallow felt Bowser's hand on the back of his head. Oh no… He wasn't gonna do what he was thinking, was he!?
"I said take my cock!" Bowser roared before forcing his dick down Mallow's throat. Mallow gurgled and moaned as he felt it. Oh, God… What had he done to deserve this?!
Bowser groaned as he he began thrusting hard down Mallow's throat. "Mmf! Nngh! Such a good fucktoy~ You like being Daddy's little slut?" He asked. Mallow could only moan in response. "I'll take that as a yes!~"
'Oh, God… This is too much! But… This is for Nimbus Land, right?' Mallow thought as Bowser continued facefucking him.
On and on it went. Bowser's groans increased while, surprisingly, Mallow's discomfort decreased. Hearts were slowly forming in his eyes as he quickly grown used to being fucked by Bowser. Actually, 'Daddy' sounded so much better~
Bowser began leaking pre as he made his announcement. "I'm getting so close! Do you want Daddy's cum~?" He moaned.
'Yes, Daddy! Give me all your cum~' Mallow thought before Bowser finally let loose. Filling Mallow's stomach with his cum. Mallow's stomach even began bulging from the sheer amount of cum that was poured into him.
When he was done, Bowser pulled away and allowed Mallow to breathe. "Hah… Hah… That was… Hah… So good~" Mallow panted.
Bowser chuckled. "Oh, but we're still not done quite yet~" He said before leaning in and whispering into Mallow's ear. "Want me to fuck you in the ass?"
Mallow shuddered in excitement. "Yes, Daddy~ I want your huge cock inside of my ass!" He confessed. Really getting into it.
Bowser gave a shit eating grin as he heard that, it seems Mallow was really excited for what's next.
"Then show me that ass~" Bowser commanded, and the nimbus happily obeyed, turning around and showing off his plump ass. Damn, if he knew that Mallow hid this kind of body with those baggy pants, he would've taken him right then and there! He gripped those plump cheeks and rubs his cock at his entrance.
"Ahh... D-Daddy... please plunge that cock inside me!~ Please Daddy, show me my place! You're awesome!" Mallow says, his body shudders as down below, his own cock was twitching.
"Oh, I'm gonna enjoy wrecking that ass, shorty~" Bowser chuckles and with that, he shoves his cock inside, groaning with pleasure and feeling the tightness around his shaft as Mallow screams with a mixture of pain and pleasure.
"Aaahn!~ F-f-f-fuck!~ S-so big!~ Daddy!~" He screamed out, a shaky smile on his face as tears welled up in his eyes. It was much bigger than he thought, but all the same, he was excited.
'F-for... Nimbus... L:-Land... F-for... N-Nimbus... Da... Daddy... For Daddy...~' His thoughts were getting all jumbled up.
"Does that hurt? Want me to take it out?" Bowser taunted. He watched as Mallow shake his head rapidly.
"N-No! Please, leave it in and fuck me! I need it, Daddy!" He pleaded. Sounding like he'll die without Bowser's cock inside of him. Well, who was he to deny him~?
Bowser began thrusting hard into Mallow's tight bubblebutt. His cheeks bouncing and jiggling all while the two of them were moaning loudly. In the heat of the moment, Bowser spanked Mallow's ass. "AH!" Mallow yelped girlishly. "Mmf! Yes! Spank me, Daddy!"
Bowser went even harder. The tip of his cock hitting Mallow's prostate a couple of times. Did it hurt? Certainly not! If anything, it only added to the pleasure~ Mallow reached down and began jerking himself off while he moved his hips in time with Bowser's thrusts.
Bowser noticed this and laughed. "Can't help yourself, huh? I don't blame ya~" He said before he started leaking pre. "I'm cumming again! YOU WANT MY CUM?!"
Mallow nodded vigorously. "Yes! Give me all your cum, Daddy! I NEED IT!" He begged.
Bowser grabbed Mallow tightly and slammed deep inside him, giving out a loud roar as he filled the needy nimbus boy up.
As for Mallow, his eyes rolled back as he felt the warm rush of Bowser's cum filling him up. Expanding his stomach some more as he moaned shamelessly. He lets out his own semen as he felt more cum inside of him.
"Aaaah!~ S-so much...! S-so... ghgh... bhghg...!" Mallow started to gurgle as he felt more of the Koopa King's seed inside, until eventually... "BLEGHGHGHGH!!!~" He puked up his cum.
Bowser watched this and couldn't help but laugh, seeing Mallow make a puddle of cum onto the floor until the Koopa stopped and pulled away. Mallow was panting and breathing heavily, but seemed to be fine. But he looked disappointed.
"Hahh... ahh... pfha... D-Daddy... I couldn't keep it in... I'm sorry..." He actually sounded guilty for not keeping it inside, despite by all means, to be impossible. "Please forgive me, Daddy."
Bowser chuckled Mallow's unneeded apology. "It's alright." He said before an idea came to him. "Say, Mallow, do you remember why you came here?"
"Hm? Uh… No, I don't think so." Mallow replied sheepishly.
"Do you remember anything at all? Say, for instance, Nimbus Land?" Bowser asked.
"I… I think I came here from Nimbus Land to see you about something." Said Mallow. Trying his damn best to recall, hell! Anything!
"Could it be that you wanted to be a true Cloud Whore?" Bowser pressed. Hoping Mallow could see what his true purpose is.
"Oh! Y-Yeah, I think that might be it!" He gasped. "Thank you, Daddy~"
"Anytime, Mallow~" Bowser responded. "Now then, get out there and show your people what you've got!"
Mallow hugged Bowser tightly. "Can I be with you, too?" He asked. Hoping that this wouldn't be a one-time thing.
Bowser hugged Mallow back. "Heheh! Of course!" He chuckled. That settled it: Mallow was gonna be in this for the long haul~
[…]
A few days later, Bowser had received word that Mallow had made it back home safely. …And that he was cemented as a permanent and public slut~
Bowser even got some photos from Mallow himself, showing off his new "role" as a new Cloud Whore. Surrounded by eager males and had a dumb smile on his face.
And he sometimes made visits to Dark Land to spend more time with his Daddy Bowser, regaling him about his stories of being a huge slut, much to the Koopa's amusement. Almost all traces of the original Mallow was gone.
And in his place...
"Come on and fuck me Daddy!~ Give me more of that cum!~" Mallow says, showing off his ass to his lovely Daddy, hearts in his eyes.
... Was a shameless and broken whore~
