It all started when applejack and applebloom went missing. For weeks Big Mac cried and mourned. Granny had passed a few years back, and so it was just him now. As big mac’s emotional state declined the farm went into decay, and the apple trees began to rot. A Month after the tragedy Big Mac was depressed, unstable, and he still had a bruise on his neck from a suicide attempt. It was at this point pinkie came along and offered to cheer him up. She took him to the sugarcube corner and offered him a whole tray of cupcakes, on the house. After pinkie left on an errand he was about to take a bite when he smelled something, it was faint but he still identified it as the stench of rot. He followed the scent down into the basement. It was there that he discovered the terrible truth
 
Blood, so much blood, that was the first thing he saw. It coated the entire room in splatters, some dried and blackened, and others seemingly still wet. He saw that there were pieces of fur and viscera in there as well. Big Mac was sickened and disturbed, what the fuck happened down there? He then noticed that a smear of blood on the ground led from what he could only identify as a medieval torture device to the door of another room, which seemed to be the source of the acrid smell. he stealed himself, and opened the door.
 
Inside was a massacre. A whole pile of bodies one on top of the other, with their age increasing the farther down he looked. Each one appeared to have been gutted, the organs removed, along with their cutie marks. He realized that he recognized some of them: There was derpy, diamond tiara, silver spoon, carrot harvest, even rainbow dash. That was when he saw, in the middle of the pile, his sisters. They were rotting, with maggots crawling through them. But even in such a state he could still make out the looks of agony, fear, and betrayal frozen on their faces. Big Mac broke down, he sobbed and stared at was remained of his beloved siblings. It was at that moment something inside the stallion snapped. Pinkie, she was the one who did this to him, the one who took away his only remaining family and ruined his life. She was the one who butchered his sisters along with so many others.
 
He couldn’t let her get away with this, oh no no no, she had to pay. she had suffer as he had suffered, as every one of her victims suffered, as his sisters suffered. He left that mass grave of a room and decided he would ambush her. He hid behind the torture rack And took some of the rope from it, waiting for the moment he could grab her. Surely enough, about 10 minutes later, pinkie came in with a basket full of baking supplies. “Too bad Big Mac left before the party started, I’m sure he would’ve tasted like apples, too” she mused to herself. She went to set the basket down on a table by her torture rack when Big Mac lunged. He pinned her to the floor and covered her mouth with his hand. Surprise was the first emotion to form on her face, then she saw the door to the corpse room had been opened, and that look of surprise was quickly replaced with one of terror.
 
“sh sh sh, quiet now, little missy, don’t want you catching any unwanted attention, now do we?” He pinned her on her back with his body, making sure to keep a hand over her mouth, and used his other arm to tie both of hers together. He hoisted her up and carried her with him to the entrance, where he then closed the door to the sound-proofed room. “There we go, you can talk now” he said as he carried her over to the rack. “I’m sorry, Big Mac, please, I’m sorry” she pleaded. “I’m sure you are, just like you were sorry when you killed all those ponies” his eyes narrowed into a malice-filled stare “like when you killed my family”. He started to tie her to the rack, with her struggling doing little to slow him down, let alone stop him. “I’m sorry, Big Mac. I didn’t have a choice, their numbers came up!” She was crying at this point, feeling pure terror as he tied her last leg in. “Their numbers, you took my family from me, you extinguished the life of a little filly who hadn’t even earned her cutie mark yet because of some RANDOM NUMBERS YOU PULLED OUT A HAT!!” His nostrils were flaring now, eyes bloodshot and filled with rage. Pinkie whimpered, she didn’t know what else to say, there was nothing to say. Big Mac went to the back wall, and picked out one of pinkies many knifes, and extra long one, and went back over to the rack. He grabbed her chin and forced her to look at him. He then smiles, for the first time in a month. “You’re my number, now” was all he said before he began his work.  
Pinkie’s screams went unheard

Fingers-in-mouth is an underrated fetish.

That feel when the fic referenced is grossed, but the Big Macintosh is sexy.

They’re perfect for each other.
