Welcome to the second story in the Caridoon Project.
Be sure to read the sequel Dusk Shine and the Mysterious Society
When she was a little filly a misunderstanding left Twilight feeling that all things considered she'd rather be a colt. She even added "Find out how to turn into a Colt" to her daily planner check list. She eventually grew up and forgot about her youthful trauma, but now she's discovered that old checklist in a box of childhood memories, and that blank, never been checked, box.
She's no longer a filly, and is sure she has the knowledge to pull off the spell if she wishes to put in the time. Seems simple. Figure out the spell, test it, change back, check off that annoying empty box. What could go wrong?
Meanwhile Pinkie Pie is desperate to learn how to play adult games so she can put smiles on the faces of those Grumpy Stallion's who she just can't seem to cheer up with balloons and confetti.
Needless to say this contains rule 63 and will have a BDSM theme of the silly variety.
While it is anthro in my imagination, I'm not going out of my way to write it like that. For the most part I think you can read it and think of them as pure ponies. Plus, my Anthro's are a lot less hung up on the idea of clothing. Nudity is common.
You don't need to read the first Caridoon Story, Applejacked, to read this one. It is a stand alone story. And Applejacked is dark as opposed to the comedy of this one.
