Spike could not believe it for the life of him. He actually did it. Something that was so vile and so insipid. He did and, and by all things holy, he now has to hide it.
"I can't let anyone observe this. What I have done, what I have created with my actions is simply beyond any belief," - he clutched an arcane object of his creation in his shaking claws.
"Spikeeeee!," - The distant echo of Spike's closest friend, Princess Twilight Sparkle rung in dragon's ears, "I'm back. Sure hope you haven't been up to any mischief and hijinks!"
"Oh no, she must not see it!" - The shaking lizard boy started stuffing the secret object inside of one of the pillows, "Yeah, she won't see it now. Perfect hiding place," - The glorified lacoste heritage bag breathed out in relief.
"Spike, why are you all sweaty and shaking?" - The Horse entered the room.
"Nooooo reason," - the crackhead looking sack was shook.
"Spike, why is the pillow all messed up? And why is there a suspicious object peaking out of it?" - The mair with flair was unto his hijinks.
"I am....so sorrry..." - Spike fell unto his knees, "The weight of this monsterous evil deed on my soul is beyond my ability to carry," - Spook was shook.
"What are you talking about?" - Twilight Ignition felt a cold shiver run down her wings.
"Don't look at me" - The Dragon dragged on.
"No, it can not be," - the watchamacall it neighed.
"Yes, it can and it is," - woah
The fabulous purple horse's tail rose, if you know what I am talking about. And if you don't, google - Do Ponies poop standing up? - I swear, the first result is a 2013 forum about bronies discussing the logistics behind horse fertilizers that come out of their bummy bum bums, it's too sweat.
Anyway, Twilight uses her majestic magical powers and levitates the secrecy incarnate from inside the Pillow. 
"Oh no..." - Twilight Facehoofed. Now her face was kinda dirty ngl, "I can not believe you actually did it," Twilight shook in disbelief. For how could she believe. She took a glance at what was once her closest friend, but he is that no more. Not after what he had done.  For how can someone be considered a friend, when they indulge in something so vain, so vile and to top it all off so sinful.
"You...you wrote MLP Fanfiction," - Twilight's voice fell.
"I KNOOOOOOOW!!" - Spike broke down, "I did it, I did it again, oh my god I am so sorry!"
"Spike...I can't believe it," - tears started swelling on Twilight's eyes, "I...how could you....I mean....what even is MLP!?" - She screamed.
"I don't knooooooooow!!" - Spike choked on his snot, " I mean what the hell is even MLP!? Am I a fan? How am I a fan for it to be a FAN-fiction? Oh god please show me the way," - the penance of the dragon was so grand yet it was much too late for it.
"How could you do it? How could you do it again!? WHAT is MLP EVEN!?" - Twilight embraced Spike in tearful grasp. She started slapping him with her hooves.
"I DON'T KNOW!" - Spike was mental
"Don't lie to me! What is MLP? Why is MLP fanfiction just writings of you having nasty passionate sex with Rarity!? What about it is MLP and who the hell can be a fan of that?" - Twilight investigated the poor dragonite.
"I don't know," - the little one graveled on the floor, "How can anyone be a fan of that? what purpose could such a vile thing serve? Who could even spend so much time of their life writing and editing such a thing!?" - That was the final straw. Nothing Spike knew to be true was a reflection of the objective universe anymore. This was the moment of the complete ego death. It was sheer darkness. What is MLP, why is it just him having sex with Rarity? And who is a fan? And why are they a fan of such a vile thing? And why did he do it? He sure did it though. He did it for real. He will pay for what he did for he did it.
"We must get to the bottom of this" - The horse was being investigative.
"Well..." - Spike cleaned his tears, "We start off by reading it then?"
"No, N E V E R do that!" - Spike was warned.
"I mean why not...it's right over there, and it's contents are just so...juicy..." - the eyes of the lizard lit up.
"This filth is going into quarantine. You made it, but we know not where it truly comes from or what is it's goal. I do feel strange power in it. I feel that eyes are drawn to it and that things that it makes people do after reading are unclean," - via telepathy, the stack of papers with the forbidden text has been sealed in a magical crystal vault.
"How did I write it, Twilight? One moment I am just sitting down in the room, minding my own business, the next moment my hands are moving by themselves. Each next word more frightening than the last one. Who could channel such filth unto me? Who actually made me DO IT?" - The defeated small critter was on his knees, begging the universe to explain how he could've become such an instrument of darkness.
"I do not know, Spike. You did it, and that is all we know. We will not rest until we know who made you do it. Until we find the source of such evil. For no sane person could bring something like this into existence," - Twilight was full of determination. Something was forcing her darling friend to write materials of intense darkness against his very will. Something evil. This needed to be stopped. 
"Only one other thing connects you and this fanfiction to this world...Rarity. We have to show her and we need to find out what is MLP." - Twilight was filled with Dedication. This can stand no more.
