When Twilight woke up the next morning, her head ached. "What a night," she grumbled. I don't think I've ever..."

Her hornlight tugged the blanket down her body, and she saw her own chest. "Thank Celestia. I'm still me."

Rarity pranced into the room. "But if you ever desire a change, you know who to talk toooo!" Rarity almost sang with delight.

"No."

Author's Note

AU Rarity works hard at turning ponies into Lunas.

But maybe she thinks the Luna x Luna shipping opportunities make it all worth it? (link to Bicyclette's Self-Shipping Contest)
