It was a bright sunny day in Ponyville, all thanks to Equestria's best flyer, Rainbow Dash! She could clear away the sky in 10 seconds flat. She may be fast, but being fast is what can get her tired and thirsty. After a few hours of busting clouds, Rainbow Dash decides to head over to Sweet Apple Acres for a cider break. Cider was the only thing Rainbow had in her mind right now, and the best cider in town is the Apple family's cider.
When Rainbow Dash got to the farm, she finds a note stuck to the front door of the house. It says:
Dear Friends,
Me and the family went to
Appleloosa for a vacation.
Won't be back til' Friday!
-Applejack
"Awww come on! How will I get some cider now?" Rainbow complained. She kick the house wall in frustration and walked away. As she walked, she noticed a pile of barrels near the entrance of the barn and went to go investigate. Rainbow checks the 3 barrels. The 2 barrels on the bottom had nothing in them, but the barrel on top was full of cider.
"Awww yeah! Jackpot!" Rainbow said with excitement. She lays under the barrel's nozzle, pulls the switch and starts drinking until her heart's content. It felt so good to have all that cider pouring down into her open mouth nonstop and wished the barrel would never run out of cider. Her belly started to bloat by each gallon she drank.
Soon, the the cider barrel became dry and Rainbow licked her lips. BUUURP* "That...was...awesome!" She said. She lunges up and walks for a bit. Rainbow's "cider belly" kept her a little off balance. Each step she took made a sloshing noise.
SLOSH* SLOSH* SLOSH* SLOSH*
"Boy was I thirsty! Well, time to get back to cloud busting!" Rainbow flapped her wings and started flying again. Her belly continued to make that sloshing noise nonstop.
After busting out some clouds, Rainbow Dash's cider belly started to rumble making her bladder alert her to a call of nature.
"Woah! That cider is starting to kick in. better get home quick!" Rainbow said to herself. She quickly sped to her home, with both of her hands holding on to her crotch. She starts to sweat, hoping she makes it before she explodes, but her "cider belly" slowed down her flying a bit. Once there, she finds that her door is locked and couldn't find a way in. She desperately searches for her key but couldn't find it anywhere. Rainbow looks through her window and sees her key on the key rack near her door.
"Oh come on! I just HAD to forget my key!" She crossed her legs in order to hold it and find a way to get in, but the rainbow water falls outside her house was making the urge to "go" much worse. There was no other way in to her Cloudominium since all the windows were shut. She decided to find a bathroom somewhere else.
Rainbow dash speeds and looks frantically for another bathroom. She sees Twilight's castle and heads there and hopes Twilight would let her use her bathroom. She gets to Twilight's door and rings the doorbell multiple times. "Hurry! Hurry! Hurry! C'mon! Open up!" Rainbow said as she kicks her knees up and down in desperation.
Spike answers the door, carrying a mop and wearing yellow rubber gloves. "Hey Rainbow, whats up?"
"Spike! I need to use Twilight's bathroom! Its an emergency!" Rainbow said as she squirmed like crazy.
"Sorry Rainbow but I am cleaning in there right now. Twilight ate a huge carrot burrito last night and...well...lets just say stomach trouble made a huge mess in there." Spike said awkwardly.
"Pleeaase Spike! It is a huuuge emergency!!!" Rainbow said while shaking her hips back and fourth with each sloshing noise from her cider belly.
"Sorry Rainbow, but no means no! I got to clean that bathroom." He slams the door. Rainbow then speeds of and continues searching for another bathroom.
While flying, Rainbow spots an old outhouse and flies down to it. "Oh thank goodness!" She said. She opens the door and tries to get in, but there is only one problem: Her cider belly won't let her. It was to big for the outhouse doorway.
"Nnnugh...nnnugh...Aww come on! Stupid outhouse doorway! I got urgent business to take care of!" said Rainbow. She tried every direction to get into the outhouse: Forwards, backwards, sideways, but she still couldn't get in. It was like try to get a rubber ball through a tight squeeze. During the struggle the outhouse toppled over onto the ground, destroying it.
"Damn it!.....(Sigh*) You know what, try not going to think about it Rainbow. Try not to think about it..." Rainbow Dash said to herself. She decided to walk for a bit and not put anything bathroom related in her mind. Each step repeated the same annoying noise from her cider belly.
SLOSH* SLOSH* SLOSH* SLOSH* SLOSH* Rainbow cringed by that noise. "Try not to think about it. Try not to think about it." She kept saying in her mind.
The walk through the park seemed peaceful. Kids were playing and families were having picnics. Soon, the sloshing didn't seem to annoy Rainbow anymore. She smiled and continued walking, thinking that her plan had worked. But all of a sudden she hears running water. She looks around and sees she is right in front of the park's giant fountain. Soon, all those thoughts about the bathroom started coming back. Rainbow grabs her crotch in order to hold it. She looks in another direction and sees and gardener using a hose at high pressure. She starts sweating and looks another way and then starts seeing a mare pour a big cup of lemonade into a filly's cup, waterfall style. That image surely wanted to make Rainbow Dash "go" where she stood.
Rainbow made a mad dash out of the park and started flying around town. Every public bathroom either had long lines or were out of order. The stores would not let her use their bathrooms unless she was a paying customer. She went to her friends houses but they too were not home.
Rainbow becomes extremely desperate and starts flying in circles. "Ughh...I'm gonna explode! I gotta take a leak somewhere!" She cried. She stops circling and spots the Everfree forest. An idea pops into her head. Why not go in a bush or a tree? Those are nature's bathrooms!
Rainbow speeds to the forest and looks for a perfect spot. She sees a tree with a big hole in the middle of it. She makes sure nobody is looking and unzips. Just as she is about to let it all out in the tree hole....
squeak* squeak* squeak* squeak* Rainbow hears a voice of a squirrel. She looks in the hole and sees some angry ones shaking their fists at her, and realizing she was about to "go" in their nests.
"Oops...heheheheheh...sorry" Rainbow says awkwardly. All of a sudden, a million angry squirrels pop up out of the trees, holding acorns. Rainbow gives them an awkward smile and starts sweating again.
"Uhhh...hi?" She says, still having an awkward smile on her face. They all started pelting her with so much acorns.
"OW! OW! OW! OW! OW! OW! OW! Alright I'm leaving!" They scared her out of the forest, next to the lake. Rainbow gets one last idea and jumps in. Soon, that cider belly started to deflate with sweet relief.
"Ahhhhhhhhhhhhhhhhhhhhhh" Rainbow says with a relieving smile. It felt so good to get all of that "used cider" out of her.
Rainbow walks out of the lake and soon, another pony jumps in for a swim. The pony swims back up and says "Wow! The lake feels so warm today." Rainbow starts to giggle and speeds off, going back to her cloud busting job.
Author's Note
Looks like Rainbow Dash will now be careful on how much cider she drinks!
