Celestia’s sun was starting its afternoon descent as Pinkie pushed the small carriage sized stroller into the heart of Ponyville.
“Erm…,” moaned Swaddle Puff as she stirred within the stroller.
“What’s wrong?” worried Pinkie before abruptly stopping to check on the displeased ‘foal’. “Sun in your eyes? Need a diaper change? Want candy?”
Pinkie lobbed a few gummy bears into her mouth as she watched Swaddle Puff appear to blush while trying to hide her face.
“Whoops!” the party pony chuckled nervously as she brought down the canopy of the stroller. “Auntie Pinkie forgot. Got to keep you cool and comfortable without too much of Celestia’s sun from hurting those little peepers of yours.”
Swaddle Puff continued to fuss while covering her face with one hoof and making groaning sounds while pointing towards downtown Ponyville with the other.
Pinkie made a nervous face as she felt her charge was getting ready to make a mess.
“No-no!” Swaddle whined. “No see! No want others see!”
Pinkie thought for a moment.
“Oh!” she gasped. “I never thought of how you may actually be a fully grown mare who doesn’t want others to see you appear to be a giant baby pony! Auntie Pinkie can fix this!”
Swaddle Puff’s pastel-pink face turned almost crimson red as Ms. Pie disappeared in a blur before returning a mere three seconds later with a shopping bag.
“We got this!” cheered Pinkie while pulling out a pair of heart-printed panties and slipping them over Swaddle Puff’s thick, Wonderbolt diaper. The size was too small and forced the bulky padding to press firmly into Swaddle’s midsection. This provided a slight illusion that Swaddle wasn’t wearing a diaper but instead had large flanks.
“EEp!” moaned Swaddle upon feeling her diaper uncomfortably tighten.
“Now!” beamed Pinkie as she got into playing dress up with the ‘foal’. “Let’s get this cute and comfy dress on you!”
Swaddle wriggled against Pinkie removing her from the stroller. However it was to no avail as she was put into the pastel-yellow dress before she could even blink.
“”Ah!” she gasped as she noticed Pinkie feeling around her diapered area. “what do? What do?”
Pinkie giggled and let out a snort.
“Making you look all grown-up, silly!” she jovially replied.
SWIP-THWIP
“Wah?” wondered Swaddle as a blue bonnet was secured over her head to help cover her eyes.
“I asked the store owner if they had bonnets for adult ponies as I know I saw some who wore them and the store owner told me they did so I got you this one to help protect your eyes as we walk through town!” Pinkie proudly speed talked as she did all sorts of over-the-top hoof motions.
Swaddle tensed up.
“No, no, no, no!” she cried. “Wanna’ go home!”
“But your Auntie Pinkie needs to go to work for a bit at the Sugar Cube Corner and promises you lots of yummy sweets if you’re good and play nice with the twins!” the fun-loving mare quickly stated while trotting alongside Swaddle Puff. “And now that you look like the grown-up mare you are you have no worries about any pony giving funny looks as we walk through town where all sorts of ponies will be finishing up their jobs, shopping, and pony watching!”
Swaddle tried to resist Pinkie’s efforts at moving her forward but to no avail.
“HERE WE COME PONYVILLE!” boomed Pinkie. “WE LOVE YOU!”
