When Rarity started to sweat, she turned on the air conditioner. When her stomach started to bloat, she took some gas pills. But now, monstrously obese, transparent, and apparently made of some sort of pony-shaped pile of goo, she couldn't think of any solutions. The only pony she knew who could help was Twilight, and she lived all the way across town!

Rarity slicked the jelloy blob that was her mane and made a sound vaguely similar to a sigh made underwater. She had to get her friend, it was the only way to fix this. Being a unicorn, her mind wasn't as easily affected as earth ponies and pegasi, so she still had a vague sense of how the world should be. As she oozed through town, passing bizarre and perverted displays of mutated ponies, she began to realize just how odd this entire day really was.

"Twrbgglbt?" Gurgled the slime pony as she oozed under the door. She looked around, only to see the bloated, living corpse of her friend on the floor. "Trrgt!" She gaked as she moved as quickly as possible toward her, only to run across something brown, chunky, and... Delicious. Rarity's body was essentially one giant orifice at this point, and the shit was absorbed almost instantly. It took a moment for her to realize what had happened, but in a moment she didn't care. The feeling of adding to her momentous body was simply too much!

Suddenly, she had an urgent desire for more. More slimy, disgusting diarrhea for more slimy, disgusting Rarity! She oozed across the floor, cleaning it spotless as she went, until she found the source. Twilight's anal ring was as thick as a pony's hoof, and could probably fit one or two inside it, making it no problem for the obese goohorse.

Twilight's body stretched to make room, but even the treadmill's curse had limits, and soon, even as the last of Rarity's slime was sucked in through her gaping anus, Twilight's impossibly obese form was covered in burning red stretch marks and areas where the skin was almost tearing, but just barely hanging on. Her bones were tightly compressed, and broken in some areas, but her organs continued functioning, barely, constantly threatening to fail, which several nonessential ones already had, despite the immense pressure of goo baring down on them. They were lucky that Twilight couldn't comprehend pain, and Rarity's body made it impossible to feel it.

Deep inside Twilight's head, two sides were struggling for control. Rarity's mind was trying desperately to merge with the empty brain, but the magic still affecting it wanted to fight her off. Just when it seemed like Rarity would have to vacate this body, a faint glimmer of Twilight bubbled to the surface of her mind. The brain also had some suppressed recollection of Twilight, and the two bonded as quickly as possible, utterly crushing the magic that destroyed Twilight's mind and body. Rarity's personality merged with them freely, and her body managed to heal Twilight's body to a healthy level, at least for a 1000 pound blob of a pony.

"I simply must find a solution for this... This... Travesty!" Shrieked Raritwi. "Who was that stallion, and why would he do this?"

Author's Note

Just so y'all know, these are all basically rough drafts. No editing, no nothing, completely glossing over things that would otherwise be multiple paragraphs long. It's unlikely that I'll ever bother expanding this whole thing into a proper story, but apparently 12 people like reading my shitty chapter drafts, so...
