Rainbow Dash stretched and flexed her legs, and rubbed at her fetlocks where the shackles had held her firm to the table. Not like it made much difference now that she was--
"HURR-URR-URR- URKK--?!"
The offending feeding tube was pulled from her stomach, dragging up with it little bits of flavor from the various sweets her boulder of a stomach was filled with.
Now able to breathe a bit better, Rainbow Dash coughed and gasped, flailing a bit in vain against her immobile gut.
"Oooohhh, you're soooo biiiiiiig!" Pinkie's voice practically dripped with ... admiration? Guh, it's not like that's the weirdest thing that's happened today.
Suddenly Pinkie's voice turned to straining grunts as Dash felt pressure against the side of her belly. It took a while for her tired and confused brain to realize Pinkie was rolling her off the table. Rainbow rolled over slowly, then suddenly fell the few feet to he basement floor, her belly hitting with a mighty BLORP, sloshing around like a water balloon. The shift in pressure made Rainbow blush and moan, followed by a loud belch.
"There, Dashie, you're free!"
"Ugh ... ha ha, very funny."
"Go on, fly away sweetie!"
"You SUCK, you know that, right?"
"Oh my! Such a potty mouth! I would get some soap to wash your mouth out with, but I think more sweets would do the job better!"
You can likely imagine Rainbow Dash's expression.
As soon as Pinkie left the room, Rainbow Dash called out as loud as she could, "TWILIGHT! HEEEELLP! HELP ME! PINKIE'S GONE NUTS AGAIN, BUT WORSE THIS TIME! HEEEEEEEEELLLLPUMFFF!"
Predictably, a cupcake was shoved into her mouth. "My my, such a noisy guest. You're right though, more guests is always better! I'll go invite Twilight as well!"
Pinkie bounced out of the room.
Rainbow Dash swallowed the cupcake and watched the pink menace leave. Hah, like she had to worry about Dash getting away. Man, she had lost it this time! What was to become of poor Twilight now? She had an idea, and didn't like the look of it.
What to do, what to do? She looked around frantically. Stairs were not going to happen, but wasn't there that huge dumbwaiter the cakes used for big orders? It should be ... ungh ... Oh right, huge belly. How to walk?
Rainbow discovered that even though not all of her hooves could touch the floor at once, she could rock around until one of them could connect, then push off from the floor or a wall. One good roll later, and her head and stomach were both spinning.
"Oh ... oh man ... ugh, let's not ... urpff ... let's not try that again ... oooohhhhh, but I have tooooooo ..."
Some time passed before she was able to make her way, one nauseating roll at a time, to the dumbwaiter. Thank Celestia the thing was nearly the size of a freight elevator! Barely able to reach the ropes that controlled the thing, she managed to crank the thing up inch by inch, sweat rolling down her face, both from exertion and from fear that Pinkie would return. All she had to do was get out near the front door and somepony would be able to see her.
Little did she know that the somepony -- or rather, someponies -- would be none other than Spitfire and Soarin of the beloved Wonderbolts.
Spitfire noticed her first, her head sticking out the door and her stomach wedged firm in the jamb. "Oh hi, Rainbow Dash! Good to see you again! ... Er, um ... you're ... you seem to have ... that is to say ..."
"You're fat!" Soarin said with all the tact of a manure truck with a wobbly axle. "You're HUGE!" His eyes and mouth opened wide.
Spitfire elbowed him in the ribs. "Soarin! Be polite!"
"But I was--"
"Shush!"
"Okay."
Spitfire fidgeted, looking for the right words to mend the horrid breach of etiquette she'd just witnessed, while Rainbow Dash desperately tried to un-stick herself from the door-frame. OH GOSH OH GOSH they must think I'm such a slob! Oh no, they'll never invite me to fly with them now! Oh, my life is oveeerrrrrr!
Spitfire decided to roll with it. "So, uh ... as Soarin oh-so-tactfully pointed out, you do seem to have gained ... quite a bit of weight ... Is that part of ... some kind of diet plan?"
Something clicked in RD's mind. "Yes! Oh -- yes! It's called, uh ... heh-heh, erm ... carbohauling! Yeah, that's it! Carbohauling! Gain a lot of weight in a hurry, and lose it all again real quick! It's the latest rage, haven't you heard of it?"
Rainbow Dash's face was now beet-red and drenched with sweat, and she hoped against hope that her two resident idols would think it was from the exercise ... which, well, it technically was. That and cosmic-level embarrassment.
"Oh wow, no I haven't! Sounds pretty intense, though! Best of wishes to ya!" She gave a little salute before leaving. "Well, been nice seeing you again, but we don't have long in Ponyville, there's an appearance we can't be late for in Canterlot! See you around!"
Soarin continued to look at the immobilized Rainbow Dash as Spitfire turned to leave. Spitfire pulled him along with a wing. "Come on, lazybones, it's not nice to stare!" Soarin finally turned and took to the sky next to his fellow celebrity.
As soon as they were gone, Rainbow managed to shove herself all the way back into the house, rolling over once more and upsetting her stomach again. "Ugh ... oh man, that could NOT have gone worse."
Then, something popped in her mind. Oh duh! She was a prisoner! She needed help! With an adrenaline-powered burst from her hind legs, she once again rolled over to the door, ready to shout at the first pony she saw -- and found herself face-to-face with the pink menace herself. Pinkie held her ridiculously large hammer comfortably over one shoulder, and had a burlap sack hanging over the other. There was a wicked smile on Pinkie's face and labored breathing from within the sack.
"Well, I am indeed impressed! You actually managed to get out of the basement! You used the dumbwaiter, didn't you! He obviously isn't very bright if he let you pass! Heehee, see what I did there?"
Rainbow Dash barely heard her as she gazed at the sack. "Is ... is that ..."
"Oh right! Our next guest!" She tossed the sack to the floor in front of her rather roughly. The mouth of the sack opened just enough to show a pale purple horn poke out from under the thick fabric.
"Oh sweet Celestia ... Pinkie, what have you --"
"Oh right! Almost forgooooot!" She said in a singsongy voice that normally would have been charming, but now made the mood even creepier. She soon returned with a small ring held in her hoof.
"Can't forget this now!" She carefully slid the ring over Twilight's horn, and it clicked into place rather loudly near the base, letting off a briht yellow glow for a moment before dimming down to a dull gold color. Dash was afraid to guess what it--
"Can't have her using her famously-ubertastically awesome MAGIC to escape now, right Dashie?" She threw a hoof around Dash's shoulder as if they were bff's out on a playdate.
Dash lay on top of her belly, frozen in shock, as Pinkie dragged Twilight down towards the stairs.
"Crap on a cracker!"
