Fluttershy was in a bit of a pickle, and she needed a solution fast. Once every ten years, a rare species of snakes make a migration across Equestria, with one of their stops being the pathway that runs past her cottage on the outskirts of Ponyville. Unfortunately, due to the actions of a certain brash pegasus and bubbly earth pony, the migration was scattered, sending the reptiles in groups all across the area. Unfortunately, due to their lack of certain senses, without additional help, they wouldn’t be able to properly regroup and continue their migrarion normally.  
Fortunately, the buttercream mare knew a solution. The only problem is that she knew that nopony would be perfectly willing to do the task, even IF she asked nicely. She was desperate for something, anything. And as if her calls had been answered, a solution ws knocking right on her cottage door.

Just outside, a certain princess and seamstress was knocking on their friends door. Twilight Sparkle and Rarity were there for their weekly tea time. After the two mares got together, certain changes had occured to their schedules, and while Rarity could not get in their spa dates as often anymore, she and Twilight still agreed to go and see her at least for a spot of tea. With a few more knocks, the door was opened, their animal-whispering friend waiting giving them a soft, yet excited welcome.

The three of them sat down at the kitchen table and poured themselves a cup of tea from the kettle Fluttershy had prepped prior to. During their time, they discussed about the usual thing, ho the animals were doing, royal duties, and the latest hot gossip. During which, Twilight and Rarity had finished a few cups of tea already, whereas Fluttershy hadn’t even finished her first. But, it didn’t matter really, the two were far too tired to notice. They did notice that, while getting tired, they were slowly getting more drowsey. They decided that perhaps it was time for them to head home, but before they could, both passed out, falling for the floor underneath them.

That was when the meek mare made her move, dragging the two off to another room, apologizing endlessly while doing so.

Groginess. That was one thing Rarity hated more than anything when waking up. She wish she could just continue to sleep, but the sun beating onto her face denied her that comfort. She figured she may as well rub the sleep from her eyes, only to find.. Her hands tightly secured behind her. This was more than enough to stir the ivory unicorn awake, making her quickly pull herself up.. Only to fall right flat onto her back. This stirred awake her marefriend next to her, who managed to sit herself up before noticing her own predicament.

Twilight realized just as quickly that she couldn’t use any of her limbs, her eyes snapping open as she groaned into whatever was keeping her muzzle locked shut. Once she heard another muffled groan, she looked down, only to fins her special somepony stuck inside of what looked like some sort of shiny snake costume, She also took notice to the part covering the entirety of her muzzle, but seeing Rarity’s chest raise and lower was enough to calm her initial worry of her love soffocating. 

She attempted to struggle against the material as well, only finding it too tight to fight against. She of course called on the next thing she could trust: Magic. Unfortunately, that failed as well, and if the ring on her marefriend’s horn was any indication, she knew why. It was then their captor walked into Twilight’s view, and as expected, who else could own pony-sized snake suits than Fluttershy. Almost immediately she began to apologize profusely to them before moving to the explanation as to why they’re trapped in the suits they were in. Despite her plea, this wasn’t enough to stop the pseudo-snakes from crying out in fear and anger. Despite this, the pegasus denied them their freedom, teling them she could only let them out after they helped her. She told them the suits would keep them comfortable, and the latex they were made from would make slithering an easy task.

Whether or not they wanted to be or not, they had no choice. If they wanted freedom, they would have to be snakes and migration leaders for a day.
