Natsu Dragneel walked excitedly with his best friend Happy. The duo of friends were heading towards Fiore Harbor to fulfill a mission! Apparently some pirates have appeared and were causing trouble for people. Strange behavior, they are very loud, explosions sometimes occur, and for some reason, they sometimes did not wear pants.


“How loud will the pirates in underwear be?” Natsu asked, thinking that it was literally a pirate band that did not wear pants.


“That must depend on the type of underwear they wear.” Happy said, imagining that there were pirates wearing boxers, others wearing tighty whities, and perhaps wearing underoos.


The pink-haired dragon slayer bumps his fists together. “I don’t care if they are pirates in underwear! I will teach them a lesson about wearing pants! Just like with Gray!”


“Aye!” The blue cat said raising his hand, sharing his friend’s enthusiasm. Thus both friends began their search through the harbor to find the pirates.



“OOHHH! Amazing! Look at this fish!” Monkey D. Luffy said excitedly as he picked up a huge blue fish with a yellow head and wings and fleshy lips. “It’s a flying fish! How do you think it tastes!?”


“Ooooohhhh!” His partner, Tony Tony Chopper, looked at it with a bright look in shock at seeing such a creature. “This place has some really unique creatures! I wonder if I can find an encyclopedia with information on all these creatures!” The little reindeer doctor was shaking his butt in excitement as he thought of all the things there were in Fiore. Now that they were shopping, they might as well check out some things.


The salesman explained to the pair of pirates that these fish are called Hane-Sakana and that the dishes made from them were surprising. (Surprisingly terrible, since not even a cat would eat these fish.) Luffy bought a pair of these fish for Sanji. After that, both pirates continued to stroll through the shops at the port.


It was only a matter of time before the two couples met, especially with Natsu's plan to find the pirates causing trouble.


“PIRATES! WHERE ARE YOU!?” The pink haired man screamed so loud he almost spit fire. “PIRATES! PIRATES! TELL US WHERE YOU ARE!”


“Natsu, I don't think that's going to make the pirates appear.” Happy said honestly.


“We are pirates.” Seemingly out of nowhere Luffy appeared with a raised hand with Chopper trying to hide behind his legs, but he was clearly there. “I'm Luffy! And I'll be the future pirate king!” He said showing his determination.


Natsu and Happy stared at Luffy and Chopper, impressed that they found the pirates so quickly. This pirate does have his pants on though.


Chopper was nervous. “Why did we come here? They look very suspicious.”


“You like being pantsless?” Happy asks directly.


“I knew it!” The reindeer exclaims with a blushing face.


“Ahh! I remember now! I’ve seen you on some posters!” The dragon slayer recognized Luffy’s face, remembering that a lot of money was being offered for him. So there was no doubt! He’s the pirate Natsu was looking for! Natsu bumps his fists together, producing fire for a moment, and smiles excitedly. “We’re here to beat them and take them to prison!”


Luffy just laughs as he adjusts his hat. “A fight? Sure!”


“A pirate hunter?” Chopper became serious, imagining that other pirate hunters or even marines were around, perhaps looking for their comrades.


Happy watches Chopper for a few moments and then points at him. “Tanuki, are you about to wet your pants? Do you need us to get you some diapers?” The blue-nosed reindeer growls, his face flushed and a furious look on his face. Something tells Chopper that he's going to hate Happy.


Natsu made the first move, running towards Luffy and punching him in the face! But to his surprise Luffy's body was still standing as his neck stretched out.


“Gomu Gomu no…” Luffy said with a smile as his head had reached its maximum distance. “…bell!” The pirate's head came back with great force, impacting against the dragon slayer's head! Natsu's eyes rolled back and he was thrown backwards until he crashed into a wall, cracking from the force of the impact.


“Natsu!” Happy pops out his wings and flies towards his friend.


“EEEEEEHHHH!?” Chopper's eyes nearly popped out of his face as he saw the flying cat. “All the animals here are capable of flight!?”


Natsu peeled himself off the wall as he rubbed his forehead. “What the hell? When I hit him in the face it felt like a pillow but his head is really hard.” Natsu shakes the dust off his vest. “This is the first time I’ve seen magic like this.”


“Now it’s my turn!” Luffy said while still smiling, causing his right arm to stretch back several meters. “Gomu Gomu no… Pistol!” The pirate launched a bullet-like punch towards the pink-haired boy. But Natsu stood firm, crossing both arms in front of his body and, with quite a bit of effort, stopping the attack. “Not bad! Hehehehe!” Luffy seemed excited to see that his opponent was strong.


“Now I’ll be serious!” Natsu said lighting his fists on fire.


Chopper gasps as he sees the fire erupt. “He’s also a Devil Fruit user!?” Neither group seemed to be well informed of the other’s abilities.


Natsu and Luffy ran towards each other, meeting in the middle and starting to exchange blows. The dragon slayer’s fiery fists rained down like a meteor shower on the pirate. But the rubber boy was quite fast, managing to respond to his fists with more punches. They kept going like this until Luffy stretched his leg back, accidentally knocking over a few barrels, and then threw a kick. But Natsu jumped out of the way, on his way to the ground the dragon slayer crashed through the awning of a shop and startled a vendor. Natsu didn’t seem to notice any of this.


“Hahaha! You won’t catch me that easy with those flashy attacks!” The fire wizard burst into flames. The flames burned away the remains of the screen and the heat melted the ice that kept the fish fresh. The vendor yelled at Natsu and said that the guild would have to pay for everything. But Natsu didn’t seem to hear anything.


“Then maybe this will be better for you, pink hair!” Luffy jumped high into the air. “Gomu gomu no… Gatling!” Now it was the pirate who was unleashing a barrage of punches.


Those who watched the port from a safe distance would see columns of fire, limbs stretching above buildings, and large plumes of dust rising as the battle continued between these 2 fierce and careless fighters. A number of crates, barrels, fishermen’s stalls, and carts were destroyed.


The fight seemed to be fairly even, though Natsu was annoyed that his punches and kicks weren’t affecting Luffy like they should have. “Gum Gum Pirate! Ready to kiss the ground and then go to jail!?” He shouted to provoke him.


Luffy wasn’t at peace either, fighting a fire user wasn’t as fun as he had imagined. “I’m not going to be defeated by a pink haired sissy boy!”


“GRRRR!!” Natsu gritted his teeth, quite furious about this. The dragon slayer jumps up and expels flames from his feet to propel himself towards the rubber pirate, managing to ram him. Although in doing so they destroyed several other fish stands in the port.


“Luffy… ahh… Luffy…” Chopper said between gasps. The cotton candy lover had been running back and forth to accompany his captain.


Happy, who had been flying back and forth without any problems, said to Chopper. “You could run faster if you left the big bags of pudding you carry in your pants.” Chopper glared at Happy but ignored him and kept running.


The first to get up from the rubble was Luffy, who had a fish in his mouth. He took the opportunity to eat it in one bite, but it affected him. “Gaaahh! Too cold!” The pirate holds his head while suffering from brain freeze.


At that moment Natsu emerged with a roar and went to catch Luffy, grabbing the first thing he found. To the pirate's dismay, it was the waistband of his underwear that was sticking out of his pants. “Wedgie's Fire Dragon!” Natsu exclaimed, as if it was a special attack, and pulled with all his might at Luffy's underwear.


“YEEEEEEAAAAAAAAKKKK!” The wedgie was surprisingly effective as Luffy went from having a brain freeze to having a butt on fire. “WEDGIEEEEE!!” The once brave and confident pirate captain screamed like a loser.


Natsu smirked, not at making his opponent squeal, but at what he had in his hands. “You’re wearing MLP underoos!? WAHAHAHAHA!” The pink haired boy started laughing.


Luffy blushed intensely, remembering that morning he had put on some brightly colored underoos with MLP ponies all over them along with pink edges. Nothing a pirate captain would wear. Having Luffy’s name on them didn’t help either.


“And you were making fun of my hair? Just look at this! They look like a little girl’s panties!” Natsu mocked and pulled on Luffy’s underwear again making him squeal. It seems the pirate was being overpowered with this. “Funny how this works so well when you were holding up so well before.” The dragon slayer laughed.


Chopper was arriving at the scene and gasps at the sight of Luffy suffering at the hands of Natsu, not to mention his underwear being displayed. “Don’t worry! I’ll help you!”


“Haaayaaaa!” Before the reindeer could do anything Happy came from the sky delivering a double kick to the back of his head.


The feline wasn’t the strongest but he managed to send the blue-nosed reindeer rolling across the ground until he crashed into a wall. Chopper collapsed on the ground, drooling, with his eyes rolled back and small flying fish circling around his head. Happy approached the reindeer, noticing that he was unconscious and with a small bulge in his pants. It seems that something in Chopper enjoyed being knocked out.


“Let me go! Let me go! You can’t do this to me!” Luffy screamed as he tried to stretch out his hands to stop Natsu. But every time his underoos were pulled a crippling pain ran through his body causing him to fail in his attempts to fight.


Natsu grins like a demon at the sight of the helpless pirate in his hands. The dragon slayer performed the wedgies he could remember: A frontal wedgie made Luffy's eyes cross as his mouth formed an oval, a squeaky wedgie made the pirate captain squeal like a pig as his lower half suffered from the underoos rubbing like sandpaper, a whip wedgie showed how stretchy the rubber pirate's underwear was as he cried pathetically and a shoulder wedgie made Luffy waddle as he saw nothing but stars.


“The underwear cutting off your ass works great. I wonder if a little more fire will do it too.” The dragon slayer slammed his fists together causing powerful flames to cover his hands and other flames to surround him, he was seriously attacking now. “Fire Dragon Fist!” Natsu charged forward with huge flames on his fists!


Luffy watched with blank eyes and tears as that huge attack came towards him. “Gyyyaaaahhhhhh!!” The pirate captain screamed before being hit by the dragon slayer’s intense flames! The attack was so effective that Luffy’s clothes were burned, except for his MLP underoos, his body embraced by the fire flew away. Luffy reached the sky and exploded like a firework and burst! People could see a huge silhouette with the pirate captain’s goofy face.


The explosion made Chopper wake up. The blue-nosed reindeer looked around in confusion. “Where am I? …Where’s Luffy?”


“Aye!” Happy said with a smile as he pointed to the sky. “There he is coming.”


Luffy fell from the sky, crashing through the roof of… a public restroom, more specifically the women’s restroom. “A PERVERT!!” A woman screamed, then the sound of a powerful slap was heard, and then Luffy stumbled out with a hand mark on his face.


The pirate captain shook his head clearing his vision and mind, realizing that he was only in his underwear! “GYEEEEH!” Luffy shrieked in embarrassment and tried to cover himself.


“Now you will try MY gatling!” Natsu took advantage of Luffy being too busy with his embarrassment and unleashed a storm of magical fire fists, seeing that these did have an effect on the rubber pirate.


Every hit made Luffy drool and make silly faces, even his little brain was turning into a giggle making the pirate smile like an idiot and, the worst part for Luffy, he started to get wet. Luffy's MLP underoos darkened and golden waterfalls fell down his legs… but there seemed to be something shaking there.


Chopper was frozen with his jaw touching the ground and his eyes fixed on his captain getting beaten up and getting wet like some kind of loser or beta boy. As soon as the reindeer snapped out of his stupor he ran towards the fight. “Don't worry Luffy! I'll save you!” Chopper shouted as he reached for the rumble balls.


“Aye!” Happy got in the way, flying inches off the ground. “Stop right there!” The blue feline also had a bag in his hand, one the reindeer knows all too well. “You can't interrupt in a fight! Besides, your big ass isn't enough of a shield!”


“My ass isn’t huge!” Chopper yelled, tired of Happy. But he got angrier when he saw that the feline had his rumble balls. “Give that back!” The reindeer prepares to attack.


The winged feline is much faster, avoiding the reindeer’s cute attack and flying after him. With a mischievous smile Happy grabs Chopper’s pants and pulls them down to the ground. The feline turns to the reader and winks with a smile.


Chopper froze as he felt the breeze, lowering his head he confirmed that his pants were around his ankles and his Care Bear underoos were now smiling at the world. “WEEEEEEEEKK!” Chopper covers his crotch, his ass shaking from nerves and embarrassment of being seen in underwear in public.


Happy had taken distance, his eyes fixed on his target. Chopper’s huge ass. “Launch!” The blue feline runs and kicks hard at the reindeer!


Chopper had listened to Happy. But the humiliation had paralyzed him, so he was kicked out like a ball out of his pants. “WOOOOOOHHHH!”


Chopper flies like a reindeer at Christmas, only instead of landing on the roof of a house he hit a stack of barrels, landing partially inside one. That was enough to make the reindeer have his eyes spinning like anime spirals. Chopper had his upper half inside the barrel while his butt and legs peeked out… and a tiny bulge formed on the front of his underoos, as if a pea had fallen inside.


Happy walked over and spanked Chopper’s ass causing it to jiggle like pudding-filled balloons. “I should have figured you were just a pet.” The feline’s eyes were able to notice the tiny bulge in the reindeer’s underoos. “Someone is quite the horny little pet.” Happy said and slapped Chopper's crotch, causing him to groan. A wet spot appeared on Chopper's underoos.


Back to the actual fight Natsu continued to dominate Luffy. Although it didn't seem like a fight anymore, as the pirate had an atomic wedgie and was bent over some rubble while the dragon slayer spanked him. Natsu wasn't even using his fire, he was simply humiliating the pirate captain for his behavior earlier.


“Waaah! No! It hurts! Please leave my ass!” Luffy didn't even have the will to fight back, his mind went back to the time when he and his brothers trained together. Luffy always lost and his brothers took advantage to humiliate him, wedgies, spankings and diapers. “Waaaah! Big brother! Stop it! I'll try harder! I can be cool!”


“No! You can't be cool! A loser will always be a loser!” Natsu said as he continued to spank Luffy’s ass. Seeing those red buttocks shake with the MLP underoos splitting them was just too much of a funny sight. “That’s why you wear underoos! Losers choose that by nature! Your only other option is diapers!”


“Nooooo! No more diapers! I already learned to go to the bathroom before going to bed! I already learned!” Luffy cried as if he was a child who was caught with a pack of diapers in his room, trying to deny reality. It was pretty clear seeing his soaked underwear.


The dragon slayer wasn’t even surprised anymore to know that the pirate captain had worn diapers. As funny as this was, he had a mission to accomplish. “Fire Dragon Spank!” Natsu’s palm was engulfed in fire and he spanked Luffy.


“YEEEEEEEAAAAAAAAKKK!!” Luffy cried, the spanking was so powerful that his soaked underoos turned to ash leaving the rubber pirate completely naked, revealing his tiny cannon to the world, showing off to the world with a micro erection. “MY BOTTY! MY BOTTY BURNS! MOMMY! DADDY! BROTHER! GRANDPA!” Luffy cried as he rubbed his ass trying to lessen the burning. Although that meant everyone could see his tiny wee wee as he did the ‘I got spanked’ dance.


“WAHAHAHAHAAHAHAHAHA!” Natsu could only start laughing at the sight of Luffy’s tiny wee wee. “You can stretch your body! But you’re the size of a baby!” With this the dragon slayer had decided to seal the pirate captain’s humiliation. “Don’t you dare leave! I have a good nose! If I have to search for you your ass will really be on fire!”


Luffy was too busy crying and rubbing his butt to even think about running away. So Natsu was able to go to one of the shops and buy some diapers for the pitiful pirate captain! All while the people at the port watched!


Natsu pushed Luffy to the ground, he squealed as his sensitive butt had to cushion the fall. It was then that the rubber pirate noticed the package of diapers. “No! No! No! Please! I beg you! Anything but that! I’ll do anything! But not the diapers! Not in front of everyone!” Luffy felt like everyone in Fiore was watching him being humiliated. And yet he was still erect! His little penis wouldn’t stop dripping pre-cum!


Obviously Natsu didn’t hear him, pulling out a yellow diaper with pictures of pink butterflies and Fluttershy on it. Perfect for a pirate who’s a fan of MLP! The dragon slayer grabs the pirate by the heels and lifts them up until Luffy’s ass is in the air, Natsu slides the diaper under Luffy’s red buttocks and lets it fall before closing the diaper over the pirate captain’s small erection. That was now hidden by the padded garment.


“This is what you deserve! You horny, submissive beta loser! You should stay in diapers to avoid dripping on the floor!” The dragon slayer sneers. “Just admit that you loved getting spanked! Little bitches like you love being humiliated in public!” Natsu lightly rubs the diaper in the crotch area.


“OHHHH!!” Luffy’s eyes cross and his hips pump against the air wildly as his wee wee erupts inside the diaper. “BLUUUURHHH!” Luffy drooled excessively while panting like a dog in heat. He had already lost all control of his body, succumbing to his submissive side and his brain clouding over.


Natsu smiles proudly at his work. “Now to sleep!” The dragon slayer raises his foot and brings it down hard on the rubber pirate’s crotch.


“EEEEEKKK! OOOOOHHhhhhh…” Luffy sounded like a squeaky toy and then like a balloon deflating. Coincidentally his bladder released everything left in the diaper. Luffy’s vision became blurry and then dark. Luffy’s body lay limp on the ground with his eyes rolled back. He looked pretty bad in his soaked diaper.


Natsu wipes his hands. “Another successful job!” He said, oblivious to all the damage done to the port shops and the destroyed things. “Up!” The dragon slayer picks up the diapered pirate and slings him over his shoulder like a sack of potatoes.


“Natsu! Wait!” Happy calls out to his friend, who was just coming over as he drags Chopper by a wedgie, ignoring his complaints. “This tanuki needs diapers too!”


“I’m a reindeer!” Chopper yells with teary eyes. A single cat poke was enough to make the reindeer’s eyes cross and his tongue poke out from his goofy grin. “I love cotton candy! They make my butt big and shiny!” Chopper then falls sprawled out onto the ground, his tiny bulge pointing to the sky.


Happy hums as he pulls off Chopper’s underoos, leaving him completely naked. The feline decided to be naughty and use the underwear to pet the reindeer’s little wee wee. The cotton candy lover reacted just like his beta bitch captain, shaking himself like a fish out of water and releasing cum like a geyser.


Happy uses the Care Bear underoos to clean Chopper and then puts a diaper on him with the same theme. Just in time because with one last shake the reindeer’s bladder emptied into his diaper. It seems that neither of them had any control.


“It seems that the mascot was following in the footsteps of his captain.” A boy pointed out, being one of the many witnesses to the pirates’ humiliation. Curiously he had a pirate hat with a green feather. His expression turned neutral almost immediately. “They don’t understand the true meaning of being a pirate.”


“I guess you don’t either.” A curly-haired boy in a lab coat commented. “Now let’s get back before our comrades get restless.”


Natsu and Happy were too busy high-fiving and celebrating their mission completion. They both carry the baby pirates and head to the guild so they can claim the reward being offered for these rowdy pirates.


---


“Idiots!” Makarov crushed Natsu and Happy with a giant fist, leaving them like waffles in a cracked hole in the guild floor. “You got the wrong pirates!”


Mirajane had a hand on her cheek as she looked at the mission sheet. “The description of the pirates doesn’t even come close to matching any of them.”


Natsu pulls his face up from the ground, blushing noticeably. “The mission included a description of the pirates!?” He hadn’t even properly checked the mission he had accepted.


Lucy, Gray, and Erza sighed as they saw the result of leaving their companions alone for a day.


Natsu and Happy became the center of attention in the guild, both exchanging embarrassed glances. Some even mocked how stupid they were while others weren't surprised that the pair of idiots made such a mistake.


Natsu forced a nervous smile as he scratched the back of his neck. “Well… I think we have some new members for the guild!” He picked up the unconscious bodies of the pirates.




In the following days Luffy and Chopper were assimilating their new job with the guild. What was that job? Well, they had become Fairy Tail's maids!


“Hey! More beer over here!” Kana shouted after finishing 6 beer mugs.


“Yes ma’am!” Luffy rushed over to carry a tray with several jars. “Excuse me for taking so long!”


Elfman slammed his fist on the table. “Where’s my food!?”


Chopper rushed over to carry a plate with large chunks of meat. “Here you go! Master!”


They both did their best to please all the members of the rowdy guild. This wouldn’t be so bad if it weren’t for the fact that they had to wear uniforms. Both Luffy and Chopper had pink slippers, long white socks, a little pink skirt, a white shirt, and a bow in their hair. The most humiliating thing was that the skirt was so short that Luffy and Chopper’s diapers were sticking out noticeably.


“Hey! Sissy boys!” Natsu shouted, causing both pirates to freeze in fear. “We’re waiting for our food and drinks over here!”


“Aye! Master!” They both exclaimed and rushed to get things for Natsu and Happy to bring to their table to avoid being punished. “Here you go! Master!”


Chopper placed the juice and the plate of fish in front of Happy. Although that didn't stop the mischievous cat from lifting up the reindeer's skirt. “EEEP!” Chopper pushes the skirt down in a ridiculous attempt to hide his diaper.


“What the!?” Natsu was annoyed to see that Luffy brought him a flying fish and beer. “I didn't ask for these things!” He stood up angrily from his seat with his fists wrapped in flames.


“EEEEK!” Luffy's eyes turned white and watery as he wet his diaper. “Sorry master! Allow this diapered loser to fix his mistake!”


“Fire Dragon Claw!” The dragon slayer exclaimed as he unleashed an attack that sent both pirates flying as their uniforms turned to ash.


“WHY AM I PUNISHED TOO!?” Chopper cries and soaks his diaper as he suffers punishment because of his captain.


Luffy was the first to hit the roof of the guild, Chopper punching him in the stomach causing him to become embedded further into the structure. Both pirates had their eyes rolled back in their heads before falling to the ground. First it was Chopper wearing only his soaked Hello Kitty diaper and then Luffy fell on top of the reindeer wearing his equally soaked pink diaper with the words ‘Sissy maid’ written in big letters on his padded butt.


Even unconscious both pirates began to shake, fucking the ground in Chopper’s case and his partner’s padded butt in Luffy’s case. They began to fill their diapers with their submissive beta baby cum.


And more days like this will keep coming until someone finally rescues this pair of loser pirates. But that doesn’t look like it’s going to happen anytime soon.
