Twilight has devised a brand new spell which uses far less thaumic energy than her teleports - swapping!

By utilizing Alicorns as singularity points in the thaumic field, she can quickly and easily swap herself with any of the other princesses at a negligible energy cost! In only a mere instant, Twilight and another alicorn swap places... a fantastic way to quickly travel to Canterlot in an emergency. She immediately plans to test her spell with Celestia, swapping herself with the regent.

What she doesn't realize is that the spell seeks out the nearest alicorn to the caster...

And it just so happens that Cadence and Shining Armor are passing by Ponyville on a zeppelin cruise.

An erotic zeppelin cruise.

Uh-oh.
