Chapter 1: Sleepless in Ponies
 
>ohcelestiaohcelestiaohcelestia
>You've been spotted
>You try to slip away, but she grabs you with magic
>Damn unicorns, magic is overpowered
>chirp
>She slams you against the wall, rendering you helpless, before throwing you down to the ground
>chirp
>She lifts up her foreleg, slamming down on you, and crushing you to a pulp
>chirp
>Your eyes rocket open, and you're back in your little crevice underneath a bush
>Another nightmare, dammit
>But you hear something outside, and it's not the chirping of that annoying fucking bird
>"Um... don't come this way! Take the path! It's, heh, way better than going through the bushes."
>Ponies
>Oh thank Celestia, you thought you'd starve to death after your last host managed to throw you up here
>You peek outside to see a young, orange filly has landed on your bush, and on the trail above is five more
>Two white unicorns, one a filly and one a mare, a young yellow earth pony filly, an orange earth pony mare, and a blue pegasus
>You decide to follow them until the right time, then maybe you can take action
>You're eatin' good tonight
 
>"No need for tents tonight, y'all. We'll just take shelter in that cave."
>Oh hell yes
>This is absolutely perfect, you found a big group of ponies and they're going to sleep soon
>You sit out in the bushes by the area they set up for a campfire, and wait
>The orange pegasus comes back with some firewood, and they exchange stories
>You try to listen, but it just bores you
>Eventually you doze off in the bush
 
>You wake up a little bit later, and the ponies are gone
>Ohshit
>You run off into the cave, and you see a little bit of light off in the distance
>Holy hell, that's a giant inflatable house
>The blue pegasus and both earth ponies lay in sleeping bags outside the house, and you assume at least one of them is inside
>Time to pick a host
 
>The earth pony filly seems pretty harmless
>With nowhere to hide, you crawl towards her in the open, though slowly and quietly so that you don't wake anypony up
>Luckily, you make it to the filly unscathed, and you get a good look at her face
>She seems so peaceful, making tiny moans in her sleep
>Her lips hang slightly loose, making it easy for you to slip your head in
>It's probably just something instinctual, since it's the way you gain nutrients, but you just love the concept of getting eaten
>You press a hoof against her teeth
>Her teeth aren't perfect, but they're taken care of well enough to not have any significant problems
>They're covered in just enough saliva to be slightly slippery
>You pry her teeth slightly open and slip straight through onto her tongue
>You lay on her tongue for just a second to appreciate how warm and soft it feels
>She involuntarily starts licking you, sucking in the rest of your tail and then pushing you around her mouth
>You get completely covered in her saliva
>It's warm to the touch, almost soothing
>Either way, you take this as a sign to stop messing around
>You take a few seconds to set yourself straight, then dive headfirst into the filly's throat
 
>You wriggle down, fighting against the muscles of the esophagus that hold you back
>The walls of her throat are slippery, making them hard to push against, and tight, trying to hold you in place
>You have experience with this stuff, though, and it only takes 30 seconds or so
>You think, at least
>You were never a good timekeeper
>You can't really be blamed, though, you've probably seen a clock all of about four times
>You're getting completely covered in the filly's acids as they slowly start to fill up her stomach
>Being immune to the acids, though, it really just feels like a hot bath
>It seems like it's been a few hours since she ate, so there's nothing really for you to feast upon
>You just lay back and listen to the sounds of her body, her stomach gurgling and groaning, her heartbeat steady and her breathing soft
>The churning of her stomach rocks you about and slowly lulls you to sleep...
 
>You're awoken to the feeling of fast shaking
>The filly is running, to, or perhaps from something
>You don't really care much though, because you figured it was time for breakfast and flopped up a storm for her
>"Applejack, when... are we gonna... get to the falls?"
>She was just barely able to make that sentence out in between the gasps
>"Just a few more minutes, Apple Bloom! Don't fall behind, we're almost there!"
>You figure you'll have to wait a few minutes longer as you slow your flopping, don't want to waste energy
>You haven't eaten in a few days, after all
>Damn that last purple unicorn, she somehow managed to teleport you out of her
>Magic is overpowered
 
>A few minutes pass, and you hear rustling from outside
>"Lunch time, everypony!"
>Finally
>You hear some chewing from above, and then what looks like the remnants of a hay sandwich land on you
>A bit generic, but hey, at this point you'll take anything
>You wolf down about half a sandwich before you're finally full
>The rest of the food you didn't eat instead dissolves into the acids around you, making up a nice chyme that covers you from head to tail
>You reach out a hoof to the stomach wall and start to rub lightly
>Most ponies like this, so you usually do it to show appreciation towards your host
>You think you're gonna come to like this filly
 
>Yeah, you've come to like this filly
>She hasn't caused you any trouble, and she always seems to know exactly where to get food whenever you're hungry
>Ever since you came across this pony yesterday, you've been having the time of your life
>"I'm off to school now!"
>"School"? What is this place she just mentioned?
>Not long after breakfast, she calls this out, then starts trotting off somewhere
>Well, you suppose you're gonna find out soon
>Once she finally sits down, you can hear an adult mare start to give some kind of lecture or something
>You sort of tune it out as you wait for lunchtime to come
>Right when it has, though, you hear a bratty young voice come from outside
>"Hey there, Apple Bloom, how are you?"
>"Uh, ahm fine. I'm guessing you want something, Diamond Tiara?"
>"Oh, nothing, just here to say hello to a good friend."
>She turns and walks away, but flicks her tail across the desk, spilling the contents of Apple Bloom's lunch on the floor
>Of course, you have no way of knowing this, you just hear the filly yell
>"Hey! I was gonna eat that!"
>"Oops, sorry."
>The sarcasm in the bully's voice is so obvious it hurts
>The day continues, Apple Bloom not getting a chance to eat at all, and you suffering as a result
>This continues for the next few days
>Wake up, breakfast, going to "School", lectures, the bratty filly does something mean, lectures, home
>It continues with little variation, occasionally she doesn't go to school for a day or two at a time
>You want to do something about this, but what? Is it worth getting found out?
 
>You figure this has gotta stop eventually. As long as your host can't figure out where your voice is coming from, it shouldn't be a problem.
"Hey."
>"Who was that? Did somepony say sometin'?"
>All the other ponies in class look at Apple Bloom like she's crazy
>"Ah could have sworn ah heard somepony..."
"Nopony else can hear me, I'm inside your head."
>She lowers her voice to a whisper
>"Who are you?"
"A voice from inside, that's all. I want to help you."
>"What'dya mean?"
"I want to help you get rid of that bully."
>"Diamond Tiara?"
>You recall your host referring to her by that name earlier
"Yes."
>"Well, what exactly did ya have in mind?"
 
>You think for a second, before a devious idea floods your mind with excitement
>It's always been hard living as the small one, so why not give ponies a chance to see that?
>Plus, you do have to make up for those lost lunches....
"Do you know any possible way you could shrink her down? Leave her effectively powerless?"
>"Maybe I could get a shrinking potion from my friend Zecora..."
"'Zecora'? Oh, so you have allies in this endeavor?"
>"Uh... yes, I have plenty of friends..."
"Friends who are troubled by this bully as well?"
>"Yeah, there's Sweetie Belle and Scootaloo..."
"Fantastic. So, you get the shrinking potion, then you meet up with these two friends at a set meeting place. Do you have a meeting place?"
>"We have a clubhouse..."
"Great. So, you will meet up with these two after you have left school?"
>"I guess so."
 
>Hours pass, and yet she still seems to wait through the rest of the lectures
>You've yet to figure out if she enjoys them, or if it's some kind of obligation
>Either way, when the ringing sound comes, like every other day, your host goes to meet up with her friends
>"Hey Sweetie, hey Scootaloo. Meet me at the clubhouse, ah got something important to talk about."
