Corruption: A Demon's Love Story

Twilight sits in front of a large magic circle, holding a large leather bound book(disgusting right) in her hands. She wears a large hooded black robe that completely covers her body, because underneath she is completely naked. She doesn’t like it, but the book recommends it. Actually Twilight doesn’t want to do this at all, because summoning demon’s always sounds like a bad idea, but she has no other option and no time to look for another one. She can’t afford to make a mistake, if she does she might be burning in the pits of the abyss or worse…

She pulls her nose out of the book and double checks the circle for mistakes. There seems to be no mistakes, and her offering is in place, a jar full of special sweets, (called ‘Devil’s Treat’) that is much prized by demons but poisonous to ponies. They say it is the sweetest sweet in existence but so poisonous to kill a creature instantly after less than a minute has passed. It is also prized by ponies wanting to commit suicide. Needless to say it is very hard to acquire.

The magic is drawn in red paint and not blood. Actually the book say that not all demon want blood sacrifice, only some of more dangerous ones and even then the sweets are a much better and somewhat safer replacement.

Twilight sighs and closes the book, placing the book beside her. It wasn’t easy to get her hands on this book, she had look in not totally legal places for it, it cost a bit too. She looks through a window at the full moon. She hopes that this works and she is not making a huge terrible mistake summoning a demon. This is going against everything Celestia has taught her, but it is her only choice, she can’t risk being discovered, she can’t risk hurting her friends. She made sure to make failsafes so if she fails the rest of Equestria won’t suffer because of this.

She turns back to the circle, closes her eyes and starts to chant the words of summon. The circle starts to glow and within minutes a magical rift appears in the middle, leading straight to the Abyss, the realm of the demons. It grows until it covers the entire circle. Twilight has to hold her robe and the book to stop it being blown away by the powerful winds that now circle the rift. The jar of sweets begin to hover in the middle of it, until suddenly something shoots out of the rift, grabbing the jar, the rift quickly closes behind it and the wind suddenly dies, causing everything that was blown about to fall to the ground.

Twilight opens her eyes and looks at the demon she has summoned, who seems to be magically floating above the circle. The demon looks pretty much like a human female surprisingly, with human’s body and head, she also has small dragon like horns, that stick out backwards, a long dragon tail, dragon-like wings, and red slitted eyes, making Twilight think if she has somehow summoned a dragon human cross instead of demon. Her skin is nearly pitch black, with her hair being a silver white, her hair is very long and straight, that looks like it would reach well past her shoulders. She wears what seems to be a armoured bra and panty, that covers her small C-cup chest and her small butt, she also wears a pair of clawed gauntlets and metal high heeled spiked-tipped boots. She also looks a head smaller than Twilight.

The demon explains the jar of sweets, before frowning. “Damn, Devil’s Treats again,” she grumbles, “How I long for something original.”

“Is Devil’s Treats no good,” Twilight says, worried that she may have mucked up.

“They are fine, but you ponies barely give us anything else,” she mumbles, continuing to check the jar, “There was time when we got anything we wanted, but that was until they found out we couldn’t resist sweets.” She opens the jar and pops one in her mouth, causing her to shudder slightly and her face scrunch up in pleasure, “Fuck, they taste so good! I hate how much I love theses. You know it was you ponies that got us addicted to these.”

But before she can take another Twilight yanks the jar away, out of reach. “You won’t get anymore until you sign the contract,” Twilight says, pulling out a piece of paper from the robe and holding it out to the demon.

The demon’s slitted eyes narrows before she grabs the paper out of Twilight’s hands. Her eyes scan the contract, she then raises a eyebrow at Twilight. “Really, that what you need?” she says, with a puzzled look on her face, “Just to service you until it is gone?”

“Yes, that is right,” Twilight says, blushing slightly and averting her eyes, shyly.

The demon looks back at the contract, “This is a really good contract,” she sighs, shaking her head, “There is no wiggling room for me at all.”

“Of course, I can’t trust a demon,” Twilight states, in a matter of factly voice, “I don’t want you doing anything bad.”

“Heh,” the demon laughs, with no humor, “So a pony can be racist about something…” she then glares at Twilight’s groin that is covered by the robe, “Well, aren’t you going to show me it first?”

“Huh?” Twilight says, confused and blushing.

“Let us see this horrible thing you want me to service until you can get rid of it,” Demon says, unhappily, “I want to see it before I sign the contract.”

Twilight hesitates at this, she really doesn’t want to show her until after she signed the contract… but she guesses it is fair that she show her. Twilight stands up, averting her blushing head and shyly removes the robe, letting it fall to the floor, revealing her curvy body, with E-cupped breasts, large and well shaped butt.... and her 20 inch long and 5 inch thick flacid cock, with two 6 inch wide balls hanging underneath them.

The demon eyes widen at the sight of the monstrous cock. “I see why you need a demon,” she says, still staring at the cock, “For only demon could use a cock that large without being ripped apart. I can’t imagine what it looks like when it is erect.”

“So, will you sign?” Twilight says, going very deep red and covering her chest, which is the only part she can actually effectively cover.

“Not until I know a few thing about this dick,” she says, crossing her hands, “First how do you have this dick? I never met a pony with a dick this large before and never even seen a dick on mare before.”

Twilight sighs and starts explains, “I was born with it, though it was once much smaller. Before I moved to Ponyville it was barely 4 inches long and barely an inch thick...”

This causes the demon to giggle. “That a really small for a pony,” she says, smirking, “That’s a child's dick!

“But after I moved to Ponyville it grew a few inches,” Twilight continues, ignoring what the demon said, “and every now and then I noticed that it grew some more, until it became this!” Twilight points at the huge member, “It nearly reaches the floor and I have to wear a special panties to hide it!”

“I can see how that could be a problem,” the demon admits, still staring at it, “But the contract ends when you find a way to remove it, so why need a demon?”

Twilight face suddenly fills with shame. “Because… because I nearly raped one of my friends a while ago,” Twilight says, hanging her head.

“Oh, go on,” the Demon says, intrigued.

“We were having a sleepover, and one of my friends forgot her pajamas and decide to just sleep in her panties, no bra or anything,” Twilight says, blushing at the memory, also not mentioning any names just in case, “At one point I woke up to go to the toilet, and I noticed that she had managed to knock off all her covers in her sleep, and was fully exposed.” Twilight face suddenly takes on a scared expression, “I don’t know what came over me, but the next thing I remember is that I have taken out my dick, removed her panties and was about to rape her while she slept!”

“Wow, though I imagine no one could sleep through getting fuck raw with that,” comments the demon, smirking.

“I managed to put her panties back on without waking her and ran to the bathroom, where I stayed until morning, trying to remove my boner,” Twilight finishes, her face full of shame, “So that I why I got to remove it, before I hurt my friends or anypony else!”

“So you need me so you can rape me instead?” the demon says, sighing.

“Basically,” Twilight admits, blushing and averting her eyes again, “I tried to remove it before when I was pretty young, but the spell I found didn’t work, most likely because it was too complicated for me back… actually I can’t remember what the spell was supposed to do. I only remember it had something to do with getting rid of my dick…. Anyway we are getting off track, will you sign the contract?” Twilight holds up the jar to show what she is getting.

The demon looks at the jar and then back to the contract before sighing, “Fine, I will sign, but only if you add two jars of marshmallows to the deal!”

“Why marshmallows?” Twilight asks, confused.

“I like them and they go well with Devil’s Treats,” states the demon, smiling creekly.

“Fine,” Twilight agrees, sighing, I mean it is not like it is hard to get or anything.

“We have a deal then,” the demon says, smiling and pulling a quill out of thin air, and writing her name on the contract, then handing it to Twilight.

“You name is Libi?” Twilight asks, looking at the contract.

“Yes, what is yours, Mistress?” Libi asks, smiling, showing that she has rather long canines.

“Twilight Sparkle,” Twilight says, blushing at being called Mistress before chant something. The magic circle fade, freeing the demon.

Libi lands on her feet and performs a quick mock bow. “So Mistress Twilight, shall we begin?” she says, walking towards Twilight, “How would you like to fuck me?”
