The Incontinence Plague (Private with Liten)
 

It has been over five months. Five months since a strange plague gripped Equestria and a few nearby towns. Ponies and any others residing in the nation slowly started losing control of their bodily functions, specifically their ability to hold in their waste. First it was their bladders. Then it advanced to their bowels. Until a cure was found, Celestia and Luna had made it mandotory for those affected to be diapered. The diaper indutries boomed.

Cadence, and her sister in law Twilight Sparkle, were currently deep in Castle Friendship's library, searching for records if any such thing occured in the past. Both wore diapers, Cadence was pink with her Cutie Mark, and Twilight's was purple with her Cutie Mark, and that of her marefriend Celestia.

Twilight was busy searching through book after book, trying to find something that would give them a clue, anything that related to what they were all dealing with now, diapers on every pony was just not something she could let continue to happen while she had the strength to fight it. Especially if the effects began to get worse, or perhaps did something else altogether.

Cadence, meanwhile, was sorting through older books. while she might not be as old as her aunts, she still had memories of her parents and of the Crystal Empire prior to Sombra's usurption. Her messy diaper squished against her, but she barely noticed now adays. If she could say it, she'd say it was oddly pleasant. Suddenly, her eyes lit up, "Twilight, I might have found something!"

Twilight rushed over to Cadence as soon as she heard. "Yes Cadence, what did-" Twilight cut herself off as she smelt Cadence's dirty diaper, her face contorting as she waved her wing to mitigate the smell. "Cadence, I know we have to find a cure for this, but you could at least change yourself when you need to." Twilight complained.

Cadence blushed, "Sorry, I guess I got wrapped up in all of this." She giggled. She held the book out, "According to this, an Earth Pony warlady by the name of Granite Heart utilized a conduit to channel her innate magic." She gestured to the image of the tanned Earth Pony. "She utilized a spell to humilate her foes before battles. She would make their entire cities incontinent, shaming them before her troops." She read on. "Knowledge of this spell shifted about after her death. Twilight, you know the Black Archives in Drakonia?" She asked

"That's, quite interesting. Yes I do know of it. You think someone is using this spell on everyone? It would take someone quite powerful to be able to do so for such a long period of time." Twilight stated as she held a wing over her muzzle, doing her best not to try to smell what Cadence had done, it was so, odd seeing somepony who used to change her own diapers wearing one now.

"That is true." Cadence tapped her chin. 'If we head to the Archives now, perhaps we can find out a way to, at least, stop this spell from growing any worse." She stood up, her diaper sagging low. "Do you need a change Twily?" She asked, as she began to change herself, humming.

Twilight blushed heavily when Cadence asked that. "N-no!" she stammered. Her diaper was clean at the moment, no telling how long that would last though. "We, we should get to the Archives quickly then, if we can at least halt it's progress, that will be a great breakthrough." Twilight said, still quite flustered.

"Right, we should pack food, water, and a lot of spare diapers." Cadence said, rubbing in foal powder and oil with a low moan. She taped up her new diaper, making sure it wouldn't leak. "Teleporting there would take too much out of us, so we'll have to fly." She said, putting the books back on the shelves. "If we go there at our top speed, we should arrive at the Archives within two days."

Two days flying, in diapers, was far from what Twilight wanted to do the most, but they had to. "Alright, once we have everything we need, we leave immediately." Twilight said as she ignored the sounds Cadence was making, going to prepare for the trip.
