With a smile on his face, the demon pushed his way through the floor and emerged into an empty room. His summoning had taken longer then he liked, and he was eager to find his target and corrupt her as he was commanded to.

“Your late.” Barked a voice from behind him.

Raising an eyebrow, the demon turned, only now noticing that a desk sat at the centre of the room, behind which a rather annoyed pink pony sat on an office chair, pen in hoof. “That's going to take some points off your presentation.” She remarked, making a note on the paper that sat before her.

The demon stood there for a moment, baffled by the turn of events. Sure he had been told to expect the unexpected, but as a demon he had assumed that would be violence, resistance, or a dogged will, not an… interview. “Please, sit.” The pink pony remarked, pointing a hoof to the chair that sat across from her. “We have much to discuss.”

The demon nodded weakly, sitting across from the pony and opening his mouth to speak only for the pink pony to cut him off again. “Let's make this quick, shall we? You are here to corrupt me and turn me into a demon pony hybrid in a bid to help Twilight take over the world.” She looked over the rim of her glasses with an amused expression. “As it stands right now you are going to have a hard time convincing me this is a good idea.”

“That may be.” The demon began. “But there are many advantages this would have for not only you but Equestria as a whole.”

The pink pony put down her pen and raised her right eyebrow. “Oh really? Tell me about these apparent advantages for Equestria. Last I checked demons running the place didn't exactly sound like a fun idea.”

“True, but we have for the large part got a bad rap as they say.” The demon smiled. “In reality we are just like you ponies, we have hopes, dreams, friends, family. We want to make Equestria grow beyond the stagnant state it is in, and in turn help all ponies everywhere to both survive and thrive.”

“Interesting.” Pinkie Pie looked down, scribbling a few notes on a peice of paper. “What sorts of advantages would I receive after I become some sort of demon pony?”

“Well for one you would be borderline immortal.” The demon smirked. “That's what most mortal beings want.”

Pinkie Pie shrugged. “That's neat, but your going to have to do better than that.”

The demon blinked. “Err, alright then.” He tapped his chin. “You would get demon magic, which is pretty cool.”

“Meh, I already got borderline toon force powers already.” Pinkie Pie replied flippantly.

“Toon force?”

“Don't worry about it, it's a meta joke.”

“Err okay.” The demon shrugged it's shoulders. “Besides that you wouldn't have to eat, or sleep, or any of those other mortal things.”

Pinkie’s eyes lit up and she suddenly leaned across the desk. “Does that mean I could eat whatever I want and never gain weight?”

The demon looked the mare up and down. “I didn't think that was an issue for you.”

Pinkie Pie’s eyes narrowed. “You have no idea how much cardio I do.”

“Err alright then.” The demon shrugged. “Yeah you wouldn't have to worry about any of that, demonic constitution basically burns away all the calories anyway.”

The pink pony leaned back in her chair, a smile growing across her face. “I’m listening.”

“Well, if you didn't have to sleep you could party all night, every night and never get tired. Plus-”

Whatever the demon was about to say was lost as the pink pony leapt across the desk, knocking him off his chair and landing in a heap, with the party pony firmly on top of him. “Sold. So how we doing this?” The party pony tapped her chin. “Is this a blood oath thing, or do I have to sign on the dotted line with my own blood or something?”

“Eww, what is it with you and blood?” The demon stuck his tongue out in disgust.

“What? It's what always happens in my pornos.”

“Your a weird mare.” The demon rolled his eyes. “Nah, nothing so strange, we just gotta fuck, and cum at about the same time. Then I melt into you and boom, demon powers.”

Pinkie Pie grinned. “Why didn't you start with that? I’ve been dying for a good lay, how much you packing big boy?”

“Enough.” He smirked, pushing up his hips and making his cock press against the lips of her pussy.

The pink pony, rather then be impressed by his offering merely sighed, shrugging to herself. “It's alright, I guess it will do.”

“What are you-oh!” The demon yelped, feeling the entirety of Pinkie’s pussy slamming down on his cock and swallowing it whole.

“Mmm.” Pinkie Pie muttered, grinding her hips against the demon’s. “Not bad, but your going to need more than that to satisfy me!”

The demon could only shriek in terror as the mare lifted her hips and slammed herself back down with such force that she nearly destroyed his pelvis. “By lucifer’s delicious teets that hurts!”

Pinkie Pie snorted. “Oh pisha, don't be such a baby, I hardly even got started yet.”

The demon’s eyes went wide. “Oh please have mercy on me.”

The party pony chuckled darkly, cupping the demon’s chin in her hoof. “Oh silly demon, if you wanted mercy, you should have tried to join with Fluttershy."

The demon stared deep within the pitiless void that were the pink pony’s eyes, noting there was neither compassion nor fear within their depths. “Fuck me.” He muttered.

The party pony stretched her now black hooves, noticing the way they elongated as much as she desired, becoming long, thin, noodle like appendages. “Neat.” She muttered, her voice having grown distorted, as if she were speaking in two voices at once.

Giving her legs a stretch, the party pony twisted her body around, noticing that her being seemed to stretch and contort without pain or difficulty. “You know what demon guy, this is actually pretty cool.” The mare ran a hoof through her black mane, noting the thin stripe of wavey pink that ran through it.

With a snap of a whip she reformed herself back into her usual state, with all her limbs becoming their usual length and size. “We should probably go see what Twilight wants now huh?”

The now demonic party pony smirked before clicking her back hooves together. “There's no place like home.” A small puff of red smoke exploded from beneath the mare’s hooves obscuring her form entirely in a flash of red.

When the smoke cleared the room was now completely empty, Pinkie Pie having vanished.
