Cadence, having been corrupted by an unknown bit of lust magic, decides to share her new... gifts. Eventually, she intends to conquer all of equestria, but there are so many pesky obstacles running around that could stop her. She'll have to chose her first target's wisely. The other alicorns seem like a wise place to start.

Luna, princess of the night and the moon, is very, very surprised when a corrosive magical swat is delivered to her ass. But that surprise quickly melts into foggy, befuddled confusion as she floats of the ground and her "full moon" starts swelling.

One has to wonder where all that extra mass is coming from. Perhaps the magic is converting something in that pretty, increasingly empty head to fill all that new space.

She certainly wont be able to stop "Empress" Cadence now.
