Story by Millow:
Recent developments caused the dairy cows to go on strike. Some kind of conflict about a pear tree growing on their favorite grazing grounds, but let’s not concern ourselves with bovine politics.
The result is that Sugarcube Corner is starting to run low on dairy supplies. Celestia knows they need milk and cream to whip up frosting and other sweet things, so the Earth ponies had to improvise a bit. Mrs Cake is already busy donating plenty of her milk to the cause, luckily for her the twins made her quite productive. At first the customers were a bit hesitant to taste the mare’s milk, but soon they grew to like the taste, with some customers in particular buying a lot more of the stock than before, awkwardly fidgeting when they get to the counter and looking quite flustered when they order the mare-milk special.
It didn’t take long until demand grew enough that the poor mother-mare wasn’t able to provide enough milk for all the orders and the twins.
After some debate the Cakes decided to take a page out of the book of friendship and ask a friend: Pinkie Pie.
Pinkie Pie was absolutely elated to be able to offer her help to the desperate bakers and agreed before she even knew what the helping-process would entail.
She blushed a bit when the Cakes described her what she would be doing, but kept eagerly nodding during the entire conversation.
On the next day, Pinkie arrived for her first shift as a dairy mare. Mrs Cake felt her jaw drop when she entered the little stall.
Pinkie, being Pinkie, went all out on the whole cow-replacement theme. She had asked Rarity to fashion her a complete cow-print getup, even a collar with a little bell. Her hair was done in a cute twin-ponytail-fashion and she even wore a pair of fake cow horns.
She was panting, biting her lip. Her hips swung rhythmically back and forth and you could hear audible sloshing noises and the pitter-patter of milk-droplets staining the floor.
Mrs Cake felt her eyes nearly bulge out when she spotted the reason for this: Between Pinkie’s hindlegs swung the biggest set of crotchboobs she had every seen. Even bigger than her own impressive pair, the milk-orbs looked taut and fully engorged.
“M-Mrs Cake! Can we plea-pleaase start!? Oooh!”
Turns out that Pinkie didn’t want to disappoint her friends on the first day of duty, so she told Zecora a little fib about a close friend of hers needing help producing milk, after which the helpful zebra shaman provided a potion to remedy that problem.
Pinkie promptly proceeded to ignore her dosage instructions and downed the whole thing this morning.
“Oh help moo! I don’t know how much moo-re of this I can take!”
