I had this idea to ponify an old Flash animation (now a YouTube video, available here: https://www.youtube.com/watch?v=guUnErBM5Bc ).
This is what I came up with. Maybe if I put in a little more work, I could easily build this story up with more words to meet the 1000-word minimum and submit this as a story.

"Just stay calm, Anon. You just lie back, now. Sometime these things just happen." Applejack said while she pushed you back down. "Twilight is working on a spell to fix everything."
You didn't have the heart to tell them that everything was fine, that your body was supposed to be proportioned like it was. There was nothing that Twilight needed to fix. But then you figured out what they were talking about and quickly shut your god damned mouth. This will all work out for the better.
After teleporting you around for most of the day, hardly staying in any place longer than half-an-hour, you fainted. Not from the casual blinking round in space-time, but from Twilight's stupidly jam packed schedule. In fact so jam packed that she didn't schedule any breaks for snacks, or lunch, or diner. Being late for your early morning meeting with the Princess of Friendship, you hastily decided to forgo breakfast. Thinking back, you couldn't remember what is was you were supposed to be doing, why she couldn't use someone else, or how she got you to agree to go along in the first place. Now, here you are, sixteen hours later, recovering in the hospital from low blood sugar levels, staring dumbfounded into a farm pony's eyes as she tried to explain something ... truly amazing.
Twilight, in her infinite purple princess privilege, got ahold of a copy of your full body magic medical scans and decided that something was needing to be fixed. That, somehow, multiple teleports had caused a vanishing of body tissue and a not small amount cell damage.
At first you were worried. Then, as one of the nurses tried to explain to you, and now as Applejack dumbs it down for you, you finally clue in as to what Twilight thought she found and her pending magical solution to fix everything. According to Twilight, rapid teleportation had caused your, ahem, "colt parts", to become "damaged" and had "lost significant mass". A panicked groping under your hospital gown had revealed that everything was the right size, where it should be, and functioned properly, at least as far as you could test without "summoning the trouser snake" in front of the freckled farm pony.
But Twilight was dead-set on returning everything to its "original size", which, when compared to pony stallions, your manhood was no longer to-scale with the rest of your body. Twilight Sparkle, the alicorn of magic and Princess of Friendship, was creating a spell to give you a bigger dick and you just shut your stupid mouth for once and tried not to grin like an idiot
