Gassiest Ship in the Grand Line, The

“Cool! That would be our new ship? I can’t believe it!” Chopper cried enthusiastic.

“I must admit it’s really a good work, carpenter” Nico Robin said apparently impassive.

“YOU’RE A REAL GENIUS FRANKY!” Luffy shouted.

“Yeah, yeah, thanks you people everybody, it’s a SUPER masterpiece by a SUPER carpenter!”.

The whole Mugiwara crew was admiring their new ship, after the Thousand Sunny had been destroyed in an engagement with the Marine.

She was actually identical to their former ship, but they weren’t clever enough to get it.

“What a wonder! How shall we call her?” Usopp asked with bulging-out eyes.

“Simple! Thousand Sunny II!” Luffy proposed laughing, only to get a kick on his head by Sanji.

“Baka! Don’t you know that giving a ship the same name as her sunken predecessor brings bad luck?”.

“Don’t worry folks! Your SUPER genius carpenter has thought also about that! Her name is…Gassy Emperor!”.

“Gassy Emperor? What a stupid name is this?” Nami said wryly.

“It perfectly explains how she works! Come with me, I’ll show you!” the carpenter replied.

So the crew jumped aboard and followed Franky on the bridge.

Alongside the steering wheel there was a long grey hose which was connected with the floor.

“What is it for?” Brook wondered pointing at it with his bony fingers.

“Well, that’s the main piece! It is connected with an engine which works a screw, so that we we’ll never have to depend on sails and wind again!”.

“And what will move this engine?” Robin demanded approaching to get a better view of the gimmick.

Franky’s eyes shone, then he replied: “Gas, of course. A gas we’ll get from these” he added showing one of his Cola bottles.

“From that? I’ve never heard an odder idea! I’d prefer going rowing!” Zoro snorted.

“You do if you want, Zoro! I trust Franky! This stuff seems cool!” shouted the captain. “But…how will we exactly take the gas out of these?”.

“It’s so simple and SUPER!” Franky cried. “Someone will drink a large amount of coke, then he or she will expel it into the hose by belching! SUPER, isn’t it?”.

“It’s….it’s…disgusting! I don’t want to be that one!” Nami protested loudly.

“Don’t worry my dear, we’ll decide it with a draw! Who gets the shortest stick out of these will be our gas producer!”.

Each of them picked a stick, then they checked what they had in their hands.

Nami was about to burst into tears.

Her stick was short, very short. The shortest one.

“Congratulations my dear! Now it’s up to you!” Franky said giving her a pat on her shoulder, while Luffy was despairing because he hadn’t gotten the role.

“Sanji, before we leave remember to buy some coke, A LOT OF COKE, GALLONS OF IT!”.

***

The Gassy Emperor was advancing trough the Grand Line, and after some weeks needed to improve the engine, Franky’s plan was now about to be started.

As agile as a cat, a barefoot Nami entered the heel room intimidated.

She was wearing a purple vest and a very sexy black miniskirt, showing her thin and long limbs.

As she was before the heel, she opened a coke package and took her first can.

She observed that bubbling brown liquid for a minute or two, then she ingested it.

How fizzy it was! How much it was tickling her throat!

Even if feeling bloated like a balloon, she kept on stuffing her face, filling her cheeks and getting a progressively expanding belly which was appearing under the shirt.

After drinking thirty packages, she felt full and was about to let out a belch.

Now her tummy had become so massive it reached the floor; cheeks and throat were filled with gas, and her boobs, arms and legs were nearly spherical; her feet could barely bear this weight.

“I’m bursting!” she suddenly thought, then, before this could happen, she put her mouth on the hose and burped, with all her strength.

Immediately the ship was thrown in the air like a rocket and fell back in the water lifting gigantic waves; everyone on board noticed that.

“SUPERRRRR!!!! IT’S WORKING!!!!” Franky shouted beating his breast.

Glad, Nami belched again, and again, and again; each time she did it the vessel went on and she deflated a little bit; “This ship would be great if it didn’t require so much gas!” she thought, before letting out a powerful “BUUUUUUUURP!!!!”.

Much to her discomfort, Sanji, now turned into a FA, couldn’t help staring at her hidden from behind.

The Emperor had travelled several miles and Nami didn’t have any more gas within her when Robin suddenly appeared, removing her shoes.

“I volunteered to relieve you. From now on we’ll work alternately”.

So she started drinking too, and the packages formed long heaps; at the end she had burst out of her black lady’s suit, experiencing a huge carbonation which made her swell up like a blimp.

“UUUUURP!!” she belched, projecting the ship forward and liberating gallons of gas.

***

After a few hours Robin’s guts had reduced in size so that she could stand up again; and it was while she was belching once more that she heard a noise of steps behind her.

“It must be Nami for the relief” she safely thought, but as she had turned an high-heeled shoe hit her in the belly, making her let out a loud burp.

While holding her tummy between the hands with pain, she looked at the intruder; it was a very tall woman, of an extraordinary beauty, followed by a long snake.

“Boa Hancock! What are you *BURP* doing here? UUUUURP!!!”.

“You listen to me!” the Pirate Empress said pointing at her with an imperious air. “I came here to save Luffy and marry him!”.

“What? He’s our captain! You can’t…” but she was stopped by another strike in the gut and fainted.

After that Hancock put all the Mugiwaras she had previously captured on a lifeboat and let them adrift; convincing Luffy wasn’t a problem since she immediately started feeding him.

“Maybe I committed a mistake…It won’t be easy to guide a ship only by ourselves…” the Amazon noticed while his “betrothed” was stuffing his face.

“Oh no, it’s not difficult!” he replied showing a full smile. “You just have to drink a lot of coke and burp into that hose!”.

She looked confuse first at the hose, then at the cans.

“If I do this, my gorgeous figure will be forever ruined” she thought.

Afterwards she opened one of them and drunk it.

“BURP! It will be a long travel to the Island of Women, so I’d better make a big provision of gas”.

The piles of cans grew, so did her belly and her cheeks.

Her already busty breast was increasingly swelling up.

By the time she has exhausted all the coke packages on the bridge she had reached complete immobility; her boobs and arms were so voluminous she could barely grasp things with hands, while guts and thighs formed a soft gassy platform.

Eyes, nose and mouth were almost sinkin in her now pudgy face and a pair of bulging cheeks.

Biting the end of the hose, the most beautiful woman in the world inhaled, then released the greatest belch she had ever released, sending the ship forward for many miles towards their “love nest”.

***

They were still on their way when a sudden roar broke the silence.

Hancock laboriously waddled to the deck: “What’s going on Luffy-kun?”.

“It’s the Marine! They’re cannonading us!”.

With no waste of time, the Pirate Empress got back to the heel room and emitted all the remaining gas she contained.

The Gassy Emperor escaped like a torpedo, but the enemy vessel were after her; distance was getting smaller over time.

“Hurry up, we must escape” the now-slim-again Hancock said catching him for an arm and loading his fellow on a lifeboat.

“But I want to fight! THAT WAS OUR SHIP!” Luffy hysterically cried while Hancock was rowing.

As the vessel was desert, many marines boarded her; they were led by a tall pink-haired female officer and by a spectacled blue-haired woman wielding a katana.

“Apparently there’s no one on board, madam” a soldier declared.

“That coward Mugiwara…he escaped again” Hina said.

“Well, let’s put ourselves to the heel” Tashigi immediately proposed.

On the floor of the bridge the two women saw a field manual left by someone and Hina picked it.

“It says the ship works through gas emitted by belches…”.

“How stupid! Shall we do it?”.

“Only if you don’t tell Smoker!”.

So Hina’s belly grew bigger and bigger, as her breasts were doing…

***

After many hours, Captain Hina had long neglected her Marine uniform to stay with only a vest and briefs, barefoot.

Two last titanic belches pushed the ship forward, then she was relieve by an identically-dressed bulging and nauseated Tashigi who waddled to the hose.

Gallons and gallons of gas pumped the engine which operated the screw; they were alone on board.

Then the Gassy Emperor shook frighteningly; it was an hidden shoal!

“Quick, we’re embarking water! This vessel will sink in few minutes!” Hina shouted separating the still blimp-sized swordswoman from the hose and using her as a gigantic flotation device.

A choir of howls attracted their attention on the hordes of FA marine staring at them.

“Smoker is going to kill me for three motives” Tashigi whimpered blushing completely. “We lost Mugiwara, we lost his ship…and well, after I’ve been seen like this by the men you can figure the third reason out”.

***

Princess Nefertari Vivi finished to gulp down the coke, then she threw away the can, letting it roll on the floor.

She hardly suppressed a powerful impulse to expel extra-carbonation.

Her enormous body had expanded to occupy almost the whole room; the gut was a cistern for dozens of gallons of CO2 and boiling liquid.

Her arms and legs had grown so much they were each the size of an hot air balloon, with ridiculously minute hands and feet sprouting from them to support the mass.

Of course she could only wear a real tight bikini, with briefs sinking between the titanic buttocks and a bra which barely prevented the giant spherical boobs from bursting out.

Having put the hose in her mouth, the princess burped; just once; put it was enough to make the Gassy Emperor become airborne for a moment.

“Cool! This ship my father found on that shoal near our kingdom’s cost is a real phenomenon! BUUUUURP!!! She was Luffy’s…Maybe I can use her to follow him and finally become a pirate? UUUUUUUUUUUURP!!!!!”.

The vessel went on taking off from and landing on the surface for many hours.
