Story by Cedric Moon:
Every pony knows all about the Grand Galloping Gala party and what goes with it that evening (the prestige of being there, but also the possibility of ending up as fat in a princess's stomach), but this year things are different! And for good reason: something has changed the game!
The opening of a portal to another world, Earth! To celebrate the welcome of the Earthlings, a "traditional" party led by Twilight (in fact, she was automatically chosen by the other princesses, leaving her no choice) and who was organized at her own palace, while another, more selective party was organized on the same evening in Canterlot!
The other princesses came for the first part of the evening, but left after a few hours, in a hurry to be present at the another party... much more "gustatory", leaving Twilight to manage the first one alone! Thanks to the special "talents" of Luna, who had contacted them all, all the guests were in fact volunteers! The princesses even had to turn some away, as so many of them were interested, much to their astonishment! Around 300 humans took part!
While Celestia was reasonable, contenting herself with eating 3 humans at a time, and as soon as they were sufficiently reduced in fat in her stomach, she swallowed 3 more and so on until a total of 15 humans ended up in her guts, it was a different story for Luna and Cadance! The two mares had thrown a challenge at each other! Who would be the most voracious princess? In truth, it was nothing new and a friendly rivalry existed between these two! As Luna had won the big gallop challenge, Cadance wasn't about to let it go! This time, she was determined to win! And, with the help of her husband, she won this time!
Each had a huge belly, with between ten and twenty humans in her belly at any one time throughout the evening, and as soon as room was made, more came to take their place in their guts! Luna devoured 60 humans that evening, but Cadance ate 61! When Twilight came to the very end of the party, the number of guests had dropped drastically! She was nevertheless able to console herself and eat a few!
As for Shining... seeing his wife eat ponies already pleased him... it was no different that evening with humans! It excited him to see Cadance swallow and digest people! To see her with that sweet, enormous, perfect belly! He'd put a lot of enthusiasm into helping her compete! And what about after digestion?
It took days, even weeks, for her to regain her usual weight! In the meantime, he was able to enjoy his wife's curves, especially her buttocks, which had become enormous thanks to a magnificent layer of fat, and her breasts, which were also becoming huge and overflowing with delicious, rich, creamy milk!
Rumor had it that their lovemaking that evening was heard far and wide!
And what about the humans? Contacted in their dreams by the princess of the night, who had first probed their minds, the rumor spread among the community of vore worshippers! Anyone who dreamed of being swallowed whole by a predator had a chance to make it come true!
The shy ones were content to hang around the princesses, keeping their fingers crossed, but the bold ones went directly to them! And having noticed that two of the princesses were swallowing quite a lot of "prey", it was only natural that they should go to them! In the end, almost half of the human guests had finished the evening as nutrients and royal fat for alicorns!
Given the number of volunteers, the fact that the princesses really enjoyed having so many of these funny hairless bipedal monkeys in their bellies (and that they didn't have the slightest difficulty digesting them), it's more than likely that this event will be repeated the following year, and no doubt the years after!
