Kill All Ponies! Humanity Fuck Yeah!

In the city of New York it was a typical misanthropic day at the Conversion Bureau, that used to be Madison Square Garden. Lines of misanthropic Human heretics were queuing up to enter the Conversion Bureau center. Soon all these Humans will become Pony xeno scum.

But then all of a sudden there was a blinding flash of light just outside the entrance of the bureau, followed by the appearance of a Blood Raven, Space Marine. A tall and buff Human, that wore thick steel red power armor.

"Heresy!" he roared.

Gary Stu, the mighty Space Marine with his massive warhammer hit the nearest fat neckbeard in the queue, thus turning his body into a bloody paste on the pavement.

Everyone screamed in terror as they ran away from the raging Space Marine as he charged through the crowd roaring and indiscriminately swinging his warhammer wildly, smashing dozens of misanthropic heretic Humans into a bloody mess.

Even the Humans that managed to get away from his deadly warhammer were cut down in droves by his hand held machine gun.

"Rrrrrraahahah! All heretics must be purged!" he shouted.

Across from the street Nicolas Cage was clapping his hands with tears in his eyes.

Gary covered in blood saluted him and then went inside the Conversion Bureau to kill all heretics.

The Space Marine went on a rampage inside the building gunning down every Human heretic in sight.

Humans panicked and screamed in terror as the Space Marine cut them all down without mercy nor pity.

"All heretics must die!"

Their screams of terror were quickly silenced as he shot down the last fat neckbeard running away from him.

He continued on his way and stepped on bloody Human corpses as he walked, crushing their broken bodies without care.

With a powerful swing of his warhammer he smashed through a wall, upon the other side he saw a pink vortex.

"I personally declare exterminatus on Equestria."

Gary jumped into the vortex, but not before he ran over to a desk to grab a crying green minted unicorn mare by the mane, whom was hiding behind a desk.

"No, please. Don't kill me! I summoned you here to save Humanity!" she said with pleading doggy eyes.

Gary used his 'Heresy Detection Senses', to his surprise he found the Pony xeno was not a heretic, in fact she had a Human fetish.

"Lyra Heartstrings, perhaps not all Ponies are heretics. Maybe I won't kill all Ponies."

Gary put the Pony down and then jumped into the portal.

***

Celestia's beautiful sun shone brightly over the land of Equestria. The birds were singing and the overly bright cartoon like landscape might give one an eye sore.

Princess Twilight Sparkle was lying on her bed masturbating to a porno magazine of Nicolas Cage.

"Oh, Nicolas Cage!" she moaned sexfully.

There was a loud crash, followed by her bedroom door going flying across the room. Gary stormed in with his warhammer ready to strike.

"Heres--- he lowered his war-hammer seeing that she was masturbating to his holiness Nicolas Cage, aka the God Emperor of Mankind. "My apologies, non heretic Pony Princess."

"Apology accepted."

With that Gary walked down the stairs. It was quiet down stairs, perhaps too quiet.

"Hmmm, my heresy sense is tingling."

Princess Celestia teleported before him, thus his 'Heresy Detection Senses' went off the charts, which filled him with a monstrous rage.

"HERESY!" he roared.

"Evil Human, you must become a Pony and--

Gary didn't listen to her as he roared charging toward her. Once close he hit her with a powerful swing of his warhammer, that sent the misanthropic Pony Princess through the roof and beyond out to space.

"Hmm, my heresy sense is still tingling."

The cowardly Celestia appeared behind the brave and noble Space Marine. With a powerful buck of her legs, she sent the Blood Raven crashing through the wall out into the street.

"Pathetic Human! I am the harbinger of your ascension!"

As she spoke Gary was already back on his feet and charging toward her with his warhammer raised.

"Die heretic!" The sly Celestia teleported away just in time, before he could hit her again with his warhammer. "Coward! Fight me like a man!"

Suddenly Rainbow Dash flew in with tears in her eyes.

"No Human wants to cum inside me!" she wailed.

Gary gasped in shock. "What kind of Human heretic wouldn't cum inside Rainbow Dash?"

"You mean... you would cum inside me, Mr Space Marine?"

"Yes, his holiness Nicolas Cage approves of Human and Pony sex and cumming inside Rainbow Dash."

Princess Celestia walked in looking down sadly.

"Heres--- Something was strange about Celestia , for his heresy sense was not tingling. "Celestia, are you no longer a heretic?"

"Yes. The evil misanthropic demon that was inside me is dead. I returned to my normal self with a Human fetish."

"Good."

"I humbly request that you also cum inside me!"

"Aww yeah! A threesome!" shouted Rainbow Dash excitedly.

The Human pulled off his power armor to reveal his massive mighty penis, that was even bigger than Zoidberg's penis.

"Let the clop begin!" he shouted.

He lay down on the floor, which allowed Rainbow Dash to mount herself on his fearsome giant spire.

"Oh, you're so big Gary!"

She bounced her fine cum-insideable booty on his giant cock. He squeezed her buttcheeks as both of them moaned sexfully. Rainbow Dash did not last long on his fearsome mighty cock, thus she came spilling her rainbow pussy juices all over his giant cock.

"Come on, cum inside me, Rainbow Dash!" Gary giving in to her request came inside her pussy. "Oh Gary." she moaned sexfully.

"Don't forget me Gary." said Celestia sexfully as she lay down beside him.

Gary stuffed his fist up her butthole, which caused her to moan sexfully in pure bliss.

And so Human and Pony xeno had great Human and Pony sex. And there was no turning all Humans into Ponies.

The End
