Last Time
Dusty teleported Brainstorm to some alleyway. The buildings were so high, that barely any sunlight got into at all. Her soaking wet body made Brainstorm feel rather cold, but that was good, as it kept the crocodile in her top asleep. There was a door leading into some brick building. Soon, the pony from before appeared.
"Very good, right on time ladies.", he said.
Brainstorm blushed at the thought of being called a lady.
The pony spoke, "Now allow me to introduce myself, I am Patch Stitch, and I have a huge line of dresses, and very few ponies to model them."
"So, I am glad you two could volunteer, to be my models."
"We're so grateful for the opportunity.", said Dusty.
"Oh! Look at the time! We've gotta get you two ready for the show!"
"Makeup!"
A team of unicorns stormed out of the building, and levitated the two into the building. Dusty was excited, but Brainstorm was feeling embarrassed, holding her hooves to her chest. Inside the building, the two were being pampered. Mane washed, combed, brushed, and fluffed. Their hooves were filed down so well, they practically looked like paws. They placed fake eyelashes, and applied lipstick on them.

They combed her tail, until it was silky smooth. One unicorn levitated a bottle of perfume, and sprayed a large cloud of perfume mist, all over them.
"COUGH! COUGH", coughed Brainstorm, after inhaling the chemicals.
Brainstorm stared at herself in the mirror. Seeing a beautiful filly, in front of her. She had forgotten the crocodile in her top, or even that she was still wearing her swimsuit.
"AH!", squealed Brainstorm, in pain, as she felt a earring clipped onto her ear.
Then, the unicorns brought over a wrack of dresses. In about a second, Brainstorm, and Dusty, were clad in very extravagant dresses. Dusty giggled, but Brainstorm was worried. The crocodile was so out cold, that he didn't even notice the change in wardrobe.
"Excuse me?", asked Brainstorm.
"Can somepony turn down the temperature?"
The other models were puzzled. The room was pretty comfortable, but Patch agreed, and ordered one of his employees to cool down the room. On stage, Brainstorm, and Dusty, paraded themselves on the runway. Striking poses, and showing off their dresses. Brainstorm had to admit, it was nice wearing mare's clothing, without having to think about whether, or not, other ponies can see that she was a stallion.

This when on until early in the night. For this particular dress, the skirt was shorter than the others, so she had to wear panties. They put her in some panties, with layers of frills on the butt, to hide the hole for her tail. The unicorns slid the undies up her hind-legs, and sent her out. It was very easy to get dressed, when some pony else was dressing you.

As she walked down the runway, ponies tried to get a peak at her panties. It was embarrassing, but Brainstorm had to tough it out. Then Patch went on stage. He thanked his models, and asked them to come up on stage. As the models were on stage, Patch whispered something to Brainstorm.
"I know a nice, and expensive restaurant, that serves some of the best meals. Care to join? My treat."
Brainstorm was hungry, but she knew something could go wrong, but he couldn't hurt his feelings. So, she tried to make up an excuse.
"But, I don't have anything to wear.", she said.
"Don't worry, what you have on is already good enough.", said Patch.
Brainstorm's stomach growled, loudly. Enough for Patch to hear.
"I'll take that as a "Yes".", and he grabbed Brainstorm.
"You'll never regret it!", and they were off to the restaurant.
