You are Anon, an aspiring young sorcerer who transports
himself to Equestria, with the intention of shrinking down
and exploring the inner world of Twilight Sparkle.

You could choose to either sneak inside her body without
her knowledge or have her spot you and possibly grant you
permission.

Here are the rules:

         1. No death (No hoof crushing, getting sat on can be a little painful, but not lethal.)
         2. No male giants or any other giantesses other than Twilight.
         3. No racism.
         4. Nothing involving bodily waste, please.
         5. Soft-vore only. I will not allow getting digested nor getting killed by Twilight's immune system.
         6. Twilight must willingly allow you to enter her body, but no giving her evil intentions.
         7. Narratives can either be first or third-person. (Never second.)
         8. All ponies, including Twilight, must be non-anthro only.
         9. No cursing, drugs, or alcohol, please!
         10. Please provide proper spelling and grammar.
         11. Stories that involve that "Osmosis Jones" trope (Living cities, sentient cells, etc.) are greatly appreciated.

Okay, then. Hope you enjoy this!
