Following an invitation from Princess Celestia to the younger princesses, all four alicorns are gathered in the Royal Spa after a wonderful evening of rest and relaxation. For Celestia, however, the evening has only just begun. For she has harbored a very secret craving for a long time, and means to indulge in the most scrumptious treats in the realm...

Her younger co-rulers.

Good old-fashioned deliciousness, in which Princess Celestia eats everypony. Expect lots of vore, in the form of fluffy, fun-for-the-whole-family Soft edition, and a teeny tiny titillation. Consider this your fair warning!

More detailed: Soft Oral Vore, and lots of it. A little bit of lactation thrown in for good measure. F/FFF, F/FF, F/F. Alicorns are very hungry creatures.
