MLP WG Greentext story: Changelings

This is a tiny Weight gain story posted on 4chan. A changeling's first mission of infiltration that involves having to mimic a heavy pony.

>This is it, your first mission
>The hive was able to kidnap a bunch of ponies from Canterlot and you along other changelings from the hive will replace them in order to infiltrate the city slowly.
>In front of you there's the 5 kidnapped ponies. Most of them normal looking except for one exception.
>"whoa nelly, you sure that's a pony?" Said your comrade next to you.
>The tied teal unicorn wasn't only bigger than the rest, it was a freaking walking beanbag.
>Boy, poor soul whoever has to mimic that one.
>"You! you will replace the big one, Whoa Nelly!" said the commander, while pointing at you.
>Of fucking course.
"You kidding, that's her name?!"
>"WRONG, that's your name now! Now transform already and go get us information!"
>Of course, my first mission had to be a big one.

>Everyone in the hive kept laughing behind my back as I left
>I felt so heavy, how the heck that fat whale of a pony is able to live like this
>Just trotting was making my whole body jiggle all over, difficulty to breath, needed to walk instead.

>Finally, I arrive to Canterlot
>Turns out, the ponies around here had the same reaction as my comrades when they saw me walking down the street with this body.
>"Hey Whoa Nelly!, today Joe's having a special on his donuts, are you going like usual?" Said a unicorn across the street.
>Suddenly I heard a loud growl.
>Fuck, I'm hungry, this body is hungry.
>I guess I could investigate the food of this place.
>Let's pay this Donut place they mention a visit... should be harmless.

>I'm in heaven
>When I reached the Donut shop, the stallion behind the counter told me I could all I want.
>"You have been our best customer for years, today, go nuts, its on the ouse
>This form gave me the ability to eat dozens and dozens of these donuts, and once I started I couldn't stop.
>I could feel my form getting heavier, but I didn't care, I will just change back after this.
>"Whoa, glad to know you are hungry today! It looks like you never have eaten donuts before the way you are eating!"
>That's because I hadn't, for some reason. Why did we need love again if there was food like this?
>There was a reason, but I couldn't remember, I'll just keep eating and..
>CRUNCH
>The chair I was using broke under my weight... this mare's body really was heavier than what I thought.
>"Oh... don't worry, I'll send the bill to your name like usual."
>Oh, so this wasn't the first time.
>I will just finish my investigation with the food and then report back to the hive.

    >....
    >"What the heck did you do?!" said my superior after I returned to the hive, still in disguised.
    "I went to eat a big donut supply sir that was meant for Whoa Nelly!" I replied,
    >"You idiot! did you skip your anatomies classes or something?!
    "Um... Yes sir! why??"
    >"You are suppose to only eat very little pony food, especially in disguise! you.... I'm afraid you don't want to switch back to your original form.
    >No way, he's just pulling my leg.
    "Look sir, All is fine, let me remove my disguise"
    >"No You idiot-!"
    >It was too late.
    >I suddenly felt so full, like I had been fed for days without stop
    >My vision was blurry, I felt like I was in a drunk state.
    >Tried to felt the ground with my hooves, couldn't reach it
    >I could feel like I was being observed by a thousand eyes
    >I could heard all my comrades around me laughing.
    >"What an idiot! what is he trying to mimic? A giant beachball?"
    >"No! He's trying to mimic those big balloons kids play with!
    >I couldn't do anything except lay there, swinging my legs trying to move but all I could feel was all the fat of my body jiggling.
    >Biggest embarassment of my life.
    >This couldn't get any worse...
