Celestia is in need of a certain princess for a special celebration that happens once every thousand years, so she spirits Twilight up to Canterlot in the middle of the night in preparation for the event. Little does her faithful student know how adorable she's going to look wearing foal clothes while she's led through the city's streets.

Warning: This is an Adult foal fic with diaper usage.
