Author's Note
This cute song helped me to write the fic, so I hope it will help you to read it as well! 
Welcome to the show
Marcus slowly regained his consciousness. He tried to move, but couldn’t do it.
No matter how hard he tried, he couldn’t do anything. And by that moment he suddenly realised: he was standing in a dark room, tied to a wall by metal plates.
More than that, he couldn’t even blink, because his eyelids were fixed with something.
Before he could say anything, a figure of a pony appeared in front of him. Seems like she came from the far side of the room. It was a gray earth pony mare with black mane and tail, blue eyes and a cutie mark as a honey bun.
“Wakey-wakey, sleepyhead! Boy, aren’t you a heavy sleeper!”
She smiled, holding an excited expression in her eyes.
He looked at her in disbelief and said something, that Honey Bun didn’t bother to hear.
“And I brought all your friends here, as well! Just look around… with your eyeballs. Your neck is fixed.”
He was shocked when he saw the mane 6 from Equus Prime. They were holded down by the same metal plates, and also had their eyelids and necks fixed, but also they were gagged with something he couldn’t recognize.
“And we’ve also have special guests from Equestria! Meet their royal highnesses, Princess Celestia and Princess Luna! ”
A big TV-like screen lighted up, showing both princesses from Equus Prime. They were worried beyond belief and shouted something, but it was muted.
Honey Bun cheerfully clapped her hooves in glee.
“Ladies and gentlemen, fillies and gentlecolts, we’re beginning our show!”
She bounced to something what seemed to be a control panel and pressed a button.
The door that nobody saw slid open, revealing Lt. Col. Cheerilee, a brave soldier and the pony Marcus was in love with.
Cheerilee looked around in shock, and gasped when she saw Marcus. She rushed to him, but the other pony grabbed her by a hind leg and tossed to the other side of the room without any visible strain.
“Now, now… What an impatient pony we’ve got here.”
She heard Marcus screaming at her and chuckled. She pressed a button on the control panel and the same gagging thing has appeared on his mouth.
“Don’t worry, pal. It’s not permanent. I just want you to be silent, when I’m talking.”
Honey Bun grabbed Cheerilee and dragged her to Marcus. No matter how hard the former teacher tried to fight back, blue-eyed pony didn’t seem to even notice her hits and kicks.
“She’s a sweet mare, I admit. Nice, kind and loyal. You’ve got a good taste, old chap.”
She was holding Cheerilee's jaws together so the latter couldn’t interrupt anything.
“I gotta admit, I also have my eyes on her. Actually, why waste time?”
And right after saying it, Honey Bun gave Cheerilee a big, deep, passionate kiss on her lips.
At that moment, everyone’s jaws dropped, except for busy gray pony and Cheerilee, whose jaw was occupied.
When the kiss ended, Honey Bun drawn back slightly and laughed.
“Oh, you should see the look on your faces!”
She narrowed her eyes.
“But now… it’s time to make things more excited.”
She hit Cheerilee right in the teeth, breaking most of them. The latter flew for several feet and crashed on the floor, her mouth covered with blood.
Honey Bun clicked a button, letting Marcus regain his ability to talk and was listening for first-grade curses and screams of rage, while Cheerilee sobbed in the corner, aimlessly gathering her teeth.
“Tsk, tsk… How rude -- cursing in front of your very special somepony.”
She giggled and gaggedg the desperate colonel again.
“And no, you can’t use your tattoos. They’re cool and all, I admit, but in here, they just aren’t working.”
She looked at Cheerilee.
“I bet she’s never cheated on you, old pal. Heh, never thought she’d be into bestiality. I mean, fucking with a human? Gross!”
Honey bun grinned brilliantly.
“Speaking of bestiality...”
She rapidly went to Cheerilee and broke her spine with one powerful stomp.
Everyone, including Princesses, were shocked and deeply affected, while Cheerilee screamed in horrible pain.
“It’s for your own good, my dear. That’s what humans are saying, when they do something like that. And you loved humans, didn’t you? Well, enjoy their hospitality.”
She placed crippled Cheerilee horizontally, with putting her rear higher than her head. She also moved a tail to a side.
“Meet my favourite pet -- Warthog the Second.”
She pushed a button, and the room was suddenly filled with deep roar, which could barely be recognized as oinking.
A huge boar entered the room, looking around with blood-filled eyes. When he saw Cheerilee, he run to her with more than clear intentions.
“Mating season is in it’s prime, guys and girls”
Honey Bun took a bag of popcorn from the near table, sat on the floor and started to watch the scene.
Over the course of several minutes, everyone in the room, except for Honey Bun were trying not to throw up. Well, Cheerilee was an exception too. She couldn’t puke, but not because she was enjoying the show. Rather because she was yelling nonstop, feeling how her privates were ripped apart.
Honey Bun also commented the rape, smirking at especially loud screams and cheering at the boar’s success.
When it was over, most of Cheerilee’s read was a mess of bloody flesh and boar’s bodily fluid.
“Buddy, you were great! I think you earned a treat. You’ll find it in your room”
She let the boar go and let Marcus speak again.
This time, she even wrote down some of his expressions, whistling impressively.
Honey Bun chuckled, observing him being mute again and helpless to do anything, even stop watching.
“Ah, what’s the matter? Disappointed that your girlfriend left you with blue balls? We’re gonna fix that!”
She took a syringe from the table and injected something in Marcus.
“Aphrodisiac. You know -- for reasons.”
She sat on the floor, waiting for effect.
When he was clearly erect, Honey Bun took Cheerilee and dragged her to Marcus.
“I bet you’ve never tried using the back door, if you know what I mean...”
She winked seductively, giggling a little.
“That said, it’s the only hole in her body that remained more or less intact.”
She placed the messy rear right against his bulge, when pulled down his lower clothes.
And after that she… just walked away from the couple.
“What? You think I will do it? Hehe… nope, you’re gonna fuck her yourself, old chap.”
She took a remote controller, and Marcus realised in horror, that his arms were moving, against his will. The frame he was tied to moved by itself, making his still tied arms to grab Cheerilee’s rump and start using her as a barely living fleshlight.
“My, my… I never thought that you’d be so eager! I bet she always denied you from it, didn’t she? But some dreams come true!”
Honey Bun was laughing at the scene, and even moreso when she saw faces of the main 6 or the Princesses’.
“Hey, Celestia! Wanna me to show you more? All of it? Of course you do; after all, you can take it!”
It took around ten minutes for Marcus to reach his involuntary climax. When he was done, Honey Bun came forth, carrying the remote control with her.
“And now… for the grand finale...”
She suddenly grabbed Cheerilee by her throat, took the knife from the sheath she was wearing and ripped her belly open, revealing lots of foul-smelling guts.
The gray pony took several guts, then coiled them around Marcus’ left hand. The other end she tied around Cheerilee’s neck.
“Hehe… you’re gonna enjoy it, lover boy!”
She took a remote controller and Marcus involuntarily lifted Cheerilee, squeezing her neck with her guts. Then his hand moved to the right, placing his girlfriend's agonized face right in front of his own.
“Oh, Marcus, how can you do this! Hanging your own lover like this… I knew that humans love domestic violence, but this… Cheerilee, sweetie, this is what called a human way of treatment."
"You deserved what you’ve got, for betraying ponies and Harmony like this. You thought that humans are noble and good, and only maligned by Queen Celestia’s “propaganda machine”? Well girl, here’s the bleak truth."
"DIE, BITCH!!!”
She enjoyed it, seeing Marcus’ heavy breathing and Cheerilee's last breath merging. It was so romantic…
“YOU WANTED THE GENOCIDE?! YOU’VE GOT THE GENOCIDE!!! DIE! DIE! DIE!!!”
Honey Bun ripped guts apart, making Cheerilee’s corpse fall back.
“Hey, Marcus, here’s your girlfriend! Your bride! Your fiance! Why don’t you kiss her?!”
She tooked the cadaver and pressed its lips against the human’s lips several times.
“Oh, and I know exactly the way for you and her to be even closer!”
Honey bun placed the corpse on the floor and started to skin it with her knife. She let Marcus speak again, but didn’t care about his shoutings and tears.
When she was done, she cut a piece of meat from a flank and left the room with it.
After some time she returned, grinning and carrying a plate with fried meat on it.
“Your order is served, sir! Bon Appétit!”
She used the remote controller to force him to hold his jaw and move them so they’d chew, while she was feeding him, controlling his tongue and pressing special spots on his body to activate swallow reflex.
“You humans are so gross and savage. I mean, look at yourself! Eating animals is horrible as it is, but you’re eating your own pony girlfriend! That sums the all up. I don’t think that any pony in any realm will ever be kind to you. I’ll make sure they’ll know everything”
Honey Bun stepped aside, taking Cheerilee’s skin with her and pushing a button.
A pack of hungry pigs filled the room as they started to gobble the cadaver.
“Eat well, my pets. You must be strong and healthy. Here, let me help you.”
She crushed all Cheerilee’s bones to dust, making sure that the pigs eat everything.
“That should do it. Now, say goodnight, everyone! Thanks for watching, hope to see you again.”
And the world went black for Marcus.
************************
He woke up on the green hill, united and free. When he jumped on his knees, he saw six corpses of ponies, burned to crisp. Each of them had a note with words:
“Hope you like BBQ!”
But before he could react, he smelled something horrible. He turned his head slowly, praying to every deity he knew to go blind.
He saw Cheerilee’s skin, filled with pigs’ excrements. It fell out her empty eyes, attracting flies.
There was also a note, on her forehead.
“Meet your new girlfriend -- Shitlee!”
