Pinkie pie buys a submarine and invites her friends along for a ride.

Why did Pinkie buy a new submarine? Do ponies even have submarines? Why would her friends agree to come along on a journey? Is this all a flimsy excuse to write a bunch of ponies having sex and make a Beatles reference?

Warnings: The answer is yes to that last question. Also Pinkie has hair tentacles and makes physics cry.

Cover art found on derpibooru after searching for yellow submarine and being delighted to find that someone made this picture. Thank you deistar for making a bunch of weird PonyxBeatles photoshops and then disappearing.

Our Friends Are All Aboard

Twilight Sparkle was confused. It wasn't exactly a novel feeling for her, and was a one she thought she had prepared herself for when Pinkie Pie had invited her to come down to the docks for a surprise. But now here she stood, flanked by her friends and staring blankly as Pinkie showed off her newest purchase.

"What in 'tarnation is that, Sugarcube?" Applejack asked the bouncing mare.

"It's a yellow submarine, duh," Pinkie responded, as if that answered the question. Technically it did, but it also opened a floodgate of followups.

"What's a submarine?" Rainbow Dash asked.

"Is it scary?" Fluttershy worried.

"Wait, do submarines even exist in Equestria? I don't think we have the technology for those..." Twilight wondered.

"Why is it such a ghastly color?" Rarity demanded to know, voice wailing in despair as the garish yellow paint-job threatened to consume her very psyche.

"Okay, here we go," Pinkie took a deep breath as she prepared to answer her friends questions. "A submarine is like a boat, but it's a super awesome boat that goes under the water, and it's not scary unless something breaks, and even then it'll only be scary for a little while until we all drown together, trapped in a watery tomb where no pony will ever be able to find our bodies, and who the heck knows what's an anachronism or not any more Twi, by season nine we're all over the place in terms of tech level, and I chose the yellow color because it looks like my son's fur color."

Her friends all stared at her in silence, trying to process everything she had said.

"Oh, ignore that last part though," Pinkie added, "Cheese won't even knock me up for another few years, and I want it to be a surprise when I tell you all that I'm pregnant."

"Umm, wait..." Rainbow began to say, still trying to process this all.

"Nope," Twilight interrupted, "Nope, don't even ask her, Dash. We all know better by this point, let's just move on or we'll be here forever."

"Yeah, thanks Twi. I mean, no one opened up this fic this just to read about all of us standing around asking each other questions. Let's just move on and get to the good part where we all have an orgy on my new yellow submarine."

"What was that about us drowning in a watery tomb?" a quiet voice questioned, unheard.

"Wait, is that why you invited us all here? To have another orgy?" Applejack asked, silently wondering if Pinkie would ever run out of excuses to have friendship orgies. Secretly, she hoped her friend never would.

"Look, Applejack, there are only two things to do with a yellow submarine: LSD trips and orgies," Pinkie explained, "and I don't see any LSD here."

"I mean, Vinyl is right over there," Rainbow pointed to the DJ chilling aboard a party boat a couple docks down, "I bet she could hook us up if we asked."

"NO!" Pinkie stubbornly insisted, "We can have a crazy drug fueled orgy later, but not right now. I bought this submarine for two reasons: because I think Ringo has a delightful voice that never got enough exposure so I really enjoy the songs he was able to sing lead on, and to have a sex party with my friends. So everyone climb aboard and let's start having sex."

With that, Pinkie opened the hatch and jumped aboard. Her friends began to follow her in, with Fluttershy needing to be pushed in by Rainbow Dash. Once they had all tumbled inside, they opened their eyes to find a giant bedroom, decorated in pink satin linen. Surrounding them were floor to ceiling windows, allowing them full view outside their vessel. The view of outside was made even more breathtaking by the fact that none of them had seen a single window on the exterior of the vessel. The fact that it was several times larger than it had looked from outside was also fairly impressive, but this isn't a Doctor Who crossover fic so no one mentioned it.

"Pinkie, how-" Rarity started to ask before Twilight interrupted.

"Rarity, I thought we agreed to stop questioning Pinkie's physics and just go with it to move this thing along and preserve our own sanity," Twilight reminded her.

"Well of course, darling," Rarity responded, "I wasn't about to ask about something so silly and trite as physical laws of reality. I just wanted to know how Pinkie managed such impressively subdued interior design inside when the outside looked so obtrusive."

"Right, of course," Twilight responded.

Pinkie stood at some sort of control panel, directing the ship to dive down and plotting a course for the land of submarines. Once they were underway, she turned around and beamed at her friends.

"Alright you guys, we're already 800 words in, time to start fucking," Pinkie ordered.

The other 5 mares, having learned long ago not to try to argue with Pinkie when she was in the mood for an orgy, began to pair off and begin. Rarity and Twilight began to feel each other up with their magic, Rainbow and Applejack jumped each other and began to wrestle on the floor to establish dominance, which left Fluttershy open for...

"Gotcha!" Pinkie laughed as she tackled Fluttershy to the ground and kissed her square on the mouth. Her tongue invaded the pegasus's mouth, running itself all over the inside. When they pulled apart, Pinkie began to slobber all over Fluttershy's face like a dog, as Fluttershy tried to prepare herself for the sex she was about to experience. Sex with Pinkie could get a little intense.

"Ready for this, Shy?" Pinkie asked as she hopped of Fluttershy and stood above her.

"I guess so Pinkie," Fluttershy's voice was a mix of hesitance and excitement.

"Okie dokie lokie, then let's get the show on the road!" Pinkie exclaimed as her mane began to writhe and extend. The mare's strangely prehensile hair began to take form, manipulating itself into three tentacles, each taking the form of a stallion's equipment. The three tendrils hovered beside Pinkie's head for a moment while Fluttershy watched, before they all descended upon the prone yellow mare at once.

"Ha, check it out! Fluttershy's getting the full Pinkie treatment!" Rainbow Dash observed as she lay on her back, pinned to the floor by Applejack, who was currently busy grinding herself into Rainbow Dash, their two pussies mashing and rubbing together. AJ was panting heavily over Rainbow as she humped away at the pegasus mare.

Fluttershy moaned as her pussy and ass were slowly pushed open by the penetrating tendrils. Once she had been penetrated as deeply as she could be, the tentacles began to pump, moving in rhythm so that one was always pushing into Fluttershy as the other pulled out. The third appendage moved to Fluttershy's front and began to trace around her mouth and snout, as if asking permission to enter the mare. Fluttershy happily granted it, taking the tentacle into her mouth and working her tongue around it. Despite being made of Pinkie's hair, the tentacle had a very pleasant cotton candy flavor to it that Fluttershy hungrily slurped at as she sucked.

Pinkie smiled in joy as she fucked her friend. She watched a small puddle form beneath the mare as her drool and arousal spilled out around the invading tendrils and combined on the floor. Pinkie's hair formed another appendage that moved behind herself and playfully penetrated Pinkie's puffy pink pleasure passage; pushing, plowing, plus pounding pink pony pussy per perpetual punishing powerful pumps. She moaned at the alliteration as the tentacle moved within her. Pinkie began to move faster inside of Fluttershy too, wanting to time their orgasms together, doubling the fun being experienced.

As this was going on, Rarity and Twilight did their best to ignore Pinkie's weirdness and just have a good time. Rarity was currently riding the alicorn's horn, moving herself up and down as Twilight sent gentle waves of magic up and trough her. Twilight's face was drenched from Rarity leaking out over it as she rode her, but Twilight didn't mind. She and Rarity had found a couple pink dildos beside the bed, because what bed owned by Pinkie Pie wouldn't have easy access to dildos beside it, and Rarity was currently pumping both of them inside of her. It wasn't long before Rarity came, spilling out all over Twilight's face. She stood up off of Twilight's horn and re-positioned herself between Twilight's legs. Twilight looked lustily up at her unicorn friend as Rarity inserted into herself the unused end of the toy inside Twilight's ass, and began to fuck the alicorn in earnest.

Rainbow Dash and Applejack had moved on from tribbing each other and Rainbow was now laying on top of AJ, the two mares facing opposite directions as their faces were buried in each other's pussies. They were lapping away at each other, determined to make the other cum first. Aj grabbed Rainbow's ass cheeks in her hooves and pulled her in closer to her face, trying to reach her tongue in as deep as she could while she tried to resist grinding against Dash's own talented mouth.

Pinkie Pie observed all that was going on around her as she tried to bring herself and Fluttershy to climax. She was always so happy to see her friends like this, writhing and screaming in the midst of passion. The party pony basked in the cacophony of noise around her: flesh beating against flesh, mares moaning and grunting in passion, the wet slurping noises that echoed around the chamber of the submarine, and the shrill screams of those taken over by passion and being pushed over the edge. Pinkie noticed that two of those screams were coming from herself and Fluttershy, as they climaxed together and coated Pinkie's tendrils in their juices.

Proud of herself for accomplishing her goal of timing their orgasms together, she moved beside Fluttershy and withdrew the tendril in her mouth to kiss her. The rest of her tentacles were still pumping away, and Pinkie moved the now free one to her ass, feeling it push inside of her as she and Fluttershy kissed.

"That was super fun, Fluttershy! You're insides feel super-duper wonderful!" Pinkie exclaimed.

"Umm, thank's Pinkie. That was, ummm, nice..." Fluttershy responded. Even after all these years, she still found having sex with Pinkie to be a little odd.

"You're welcome, Fluttershy," Pinkie said, gently nuzzling her friend's face. "Alright, this is going great, but I'm still feeling super horny, so let's move things along and kick this party into full gear!" Pinkie said excitedly, and moved into the center of the room, standing on her hind legs atop the bed.

From out of Pinkie's hair expanded countless more tendrils of hair, writing and squirming through the air in search of a body to enter. Each of her friends were found in turn, some tentacles lifting them up off the ground as others invaded each of their orifices. Mouths, cunts, and asses alike were invaded by Pinkie. Pinkie stood in the center as the other five mares were lifted and shaped into a circle around her, still pumping herself as she took her friends.

Pinkie did her best to focus on each of them individually, fucking them the way she had catalogued how the liked it. Rainbow and Applejack were taken hard and fast, the tentacles pumping into them with all the force Pinkie could pass through them. For Rainbow in particular, Pinkie summoned other tendrils to play with her hooves, gently tickling them the way the pegasus liked. Rarity was taken gently, and Pinkie played with her horn as she fucked her, jacking a tendril up and down the protrusion as she took the alabaster mare. Twilight was given an extra thick appendage ups the ass, Pinkie knowing of the alicorn's preference for taking ponies up there. And for Fluttershy? Well, Fluttershy likes to keep some of her fetishes secret, so I'm afraid we won't be sharing those with you, dear reader. She would be super embarrassed if we told you how Pinkie changed the shape of her invading tendrils to mimic certain animals that were definitely not ponies, so we won't be telling you that.

...umm?

"Not now, narrator," Pinkie spoke in frustration, "we're getting to the climax of this story, so don't sweat the small stuff."

With that, Pinkie drew her friends in closer to her, appearing almost as a single ball of multicolored pony flesh as they all pressed together. The tentacles inside their mouths withdrew, and their mouths fell on their host, licking and kissing and biting at Pinkie's flesh as she pumped them full. All six mares shivered and came with a tremendous scream, losing themselves to the pleasure and ecstasy provided by Pinkie. Afterward, Pinkie set them all down with tender love and the six friends moved together to cuddle in the damp puddle of their pleasure in the middle of the bed.

As they lay in the afterglow of sex, Twilight looked out the windows of the submarine. She gasped as she saw that they were currently floating over a vast underwater city. Giant and ominous, the buildings looked wrong somehow, as if their geometries didn't quite belong in the real world. The whole place looked ancient and timeless, and Twilight wondered at what kind of creatures had built a place the radiated such malice. She shivered at the sight of the ancient abomination and stepped back to the safety of her friends.

"Pinkie, what is this place?" Twilight asked, pointing a shaking hoof out the window and toward the city.

Oh, that's just R'lyeh," Pinkie answered casually, handing out water bottles to her friends to help them all recover from their orgy.

"Thanks Pinkie, this hit's the spot," Rainbow said as she lay atop Fluttershy and drank greedily. The other girls echoed her thanks, appreciating the chance to re-hydrate after spilling so many fluids out across the room and each other.

Pinkie noticed Twilight's look of incomprehension and rolled her eyes.

"Geez, Twilight, I thought you were supposed to be the smart one," she teased. "You know, the nightmare corpse-city R'lyeh. Haven't you ever heard the old saying? Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn? Or something like that anyway, I can never pronounce 'mglw'nafh' right. Anyway, I'm pooped, what say we sail back and head over to Sugarcube corner. Mrs. Cake promised she'd have some treats ready for us when we got back from our voyage."

And with that, Pinkie steered her yellow submarine back ashore, where all the ponies had desserts and then headed home. And deep below the sea, lurking in timeless depths, he watches; Immortal, dwelling in madness and insanity, ever growing closer to the time of awakening. For that is not dead which can eternal lie, and with strange aeons, even death may die.

But in the meantime, Pinkie Pie slept soundly that night, dreaming of the next time she and all her pony friends could have sex with one another.

Author's Note

Yeah... I don't even know. This is apparently what happens when I try to write Pinkie Pie. Like, I had no intention of there being hair tentacles in this, she just kind of manifested those as I wrote her. Pinkie is a gateway to the black abyss of madness from which there is no escape.

But at least there's candy and streamers down that abyss, girl knows how to throw a party.

Hope you enjoyed whatever this was, at least.
