An enormous multicolored cloud flew toward Earth. If one looked closely they would see the cloud is made up of countless tiny nanomachines in the shape of equines of all colors of the rainbow and beyond. The nanomachines tended to stick together with other nanomachines of the same color, leaving small gaps in the swarm between each nanomachine group.

One of the nanomachine groups stood out from the rest, they were white in color, which was not uncommon… but it was also five times the size of Earth. The hundreds of billions other nanomachine groups were merely the size of elephants.

However, there were four other large groups of nanomachines, one was a dark blue group of nanomachines that was four times the size of Earth, there was a group of pink nanomachines that was three times the size of Earth, which gently touched off a small elephant sized group of white nanomachines in very close proximity.

And finally the smallest of the giant groups was of purple color and was only twice the size of Earth.

On Earth itself fear gripped humanity. There were riots in the streets, looting and people setting things on fire and stuff, people held signs ‘It’s the end of the world’ and basement dweller misanthropes were masturbating vigorously to the apparent oncoming apocalypse of pastel robot horses from space.

Back out in space, a faint glow emitted off the massive dark blue group of nanomachines as she telepathically spoke in a concerned tone to the even more massive white nanomachine group. "Sister, humanity seems rather scared. Are you sure they are ready to receive our tender affection?"

"Don’t worry Luna, once they know of our peaceful intentions they will calm down soon enough," she spoke in a sweet angelic voice.

"I hope you’re right Celestia. I want to feel them unleash their reproductive material inside me. I want to feel their love," she said in a soft sensual tone.

The pink group of the nanomachines suddenly glowed with faint light. "Don’t worry, our big fat pony butts will work their magic on them. The Bronies among them will be the first to embrace our butts."

"My wife is right," spoke the small group of nanomachines next to the massive pink one. "Humanity will not be able to resist the sexyness of your butts for long."

A sad sigh came from the massive purple nanomachine group. "Sadly brother not all of humanity will love our butts. Not everyhuman is into robot horse pussy."

"Yeah, you might be right Twilight. I just hope some day all of humanity will love our butts," spoke the massive pink nanomachines in a sad tone.

"I’m afraid Cadence that will never happen, there will always be some stubborn humans who won’t ever like our butts no matter what," spoke Twilight in a sad tone of her own.

"Come on everypony, cheer up! We have some sexy humans to meet!", shouted Celestia excitedly.

With that everypony cheered in joy, before flying down into Earth’s atmosphere in a sea of pastel colors.

In the land of US And A, inside the White House, within the oval office George W. Bush was sat behind his desk. Sweat poured down his face over the terrifying news of tiny robot horses rapidly approaching Earth.

"President Bush, I wish you to be my special somehuman," spoke Celestia’s voice inside his head.

Bush panicked, jumping to his feet. "What?! How are you-- there was a blinding flash of light, followed by the appearance of a massive, towering white alicorn with a fleshy body like form before his desk. "Aaaahhh! How did you get in here?!"

"Greetings, I am Princess Celestia, us robot ponies come in peace."

George W. Bush, nobel peace prize winner used his amazing diplomatic skills to make a great first impression of humanity with the robot ponies by saying the following. "I know the human being and robot pony can coexist peacefully."

With that Bush and Celestia stared deeply into each other’s eyes, before slowly, very slowly the two came together to kiss passionately in a tender display of human and robot pony love.

Bush never thought kissing a robot horse would feel so nice. Despite the mare being a robot her lips felt soft and amazing just like human women's lips.

Across the city of New New York, humans screamed and ran in terror as the swarm of nanomachines dropped to the surface, whereupon landing the nanomachines compressed together to form small, 4 foot tall pastel cute and sexy pony robots.

The robotic ponies looked at the humans with bedroom eyes as they walked toward them. The military and the police engaged the vast horde of the lust filled eyes of the pastel robot ponies.

The robot ponies giggled and even some of them moaned sensually as the bullets hit them. The holes in which the bullets made upon the ponies were quickly repaired in seconds by the nanomachines. Soldiers panicked backing away, as the ponies relentlessly marched forward.

The humans screamed like little bitches before the ponies stood up on their back hind legs, before taking hold of them… and…. and…. and… merely hugged them with their hooves wrapped around them and nothing else.

The humans became confused over this, thinking they were going to be eaten alive by zombie robot ponies.

The adorable and sexy robot ponies quickly reassured the humans by just continuing to hug them and being terrifyingly cute. However, for some of the humans this did not work, after a few seconds of being hugged said humans growled angrily, before pushing the pony over.

The cute and sexy ponies cried over their rejection of hugs, crying like a baby before the humans that knocked them over. Some of the humans felt guilty over what they did, thus they knelt down and hugged the pony. The ponies on the ground gasped in joy, before returning the hug with gusto and forgave the human.

However, some humans were big meanie pants and merely walked away, leaving the crying pony. But some nice humans approached the sad ponies and hugged the ponies without a human to hug and made them happy again.

The big meanie pants humans that don’t like pony hugs banded together, looking on in confusion of their countrymen being so easily seduced by cartoonish robot horses. Even some of said humans vomited at the sight of seeing their fellow humans kiss the ponies.

Back in the white house, Celestia was bent over the desk with her massive white fat ass as Bush fucked her up her silky soft butt.

"Oh Bush! The magic of friendship between organics and machines is truly wonderful. I hope all of humanity will worship us, your friendly and sexy pony friends."

All across Earth the moans and groans and the slapping of flesh against artificial flesh could be heard as millions of humans had sex with the robot ponies, some humans having sex with multiple ponies at the same time. Their robot pussies being able to shapeshift into the perfect size for each of their human lovers had made it a great experience. The ponies' bodies were warm and cuddly, they were so cute and sexy and they had massive fat butts of an ass man's dream come true. And also their synthetic flesh was softer than silk and their long tongues were perfect for giving blowjobs.

One by one, the humans fell before the cute and sexy immortal robot ponies.

In mere decades almost the entire human race worshiped the sexy robot ponies. Small pockets of resistance was here and there, but ultimately the entire world was ruled by the sexy robot ponies.

There was world peace, no world hunger, the Earth and the sun never aged anymore thanks to fancy robot pony technology and no human on Earth suffered blue balls. Apart from those weird humans from the Human Liberation Front, they still got blue balls, who babbled on about fighting to free humanity from enslavement and other nonsense.

The efforts of the big meanies of the Human Liberation Front were pretty much useless, shooting at random robot ponies with guns didn’t seem to do anything, other than make the robot pony cry and trot away over rejection of love. However, hanging up signs that said: ‘No Robot Ponies Allowed’ worked quite well, as the robot ponies respected the humans wishes not to see robot ponies in the area. Unfortunately, there were very few of such places, which tended to have names like ‘Last Hope’ or ‘No Horse Fucking Town’.

The immortal robot ponies being able to give birth to human children and create even more robot ponies as well ensured the survival of humanity. And when humans became old enough they were permitted to date a robot pony or a human if they wished, however most chose the robot pony because robot pony pussy was best pussy.

The immortal robot ponies were sad to see their mortal human lovers die of old age, but when the next generation are adults they will carry on the love between organics and machines.

Forever and ever there was human and robot pony sex. Apart from the humans of the Human Liberation Front not joining in on the action, because they were boring prudes, that only had sex with other humans.

The robot ponies did not stop with Earth, protecting their sexy humans in space ships the ponies traveled the stars, establishing colonies for humanity throughout the universe. The robot ponies met even more people to make love with in the form of sexy alien friends, they too like humanity were stubborn at first, but learned to love the ponies too.

Like Earth, the robot ponies made their home worlds a never dying planet and their sun a never dying star.

And just like humanity, the ponies brought the aliens along with them too in order to establish even more colonies. The robot ponies were also capable of giving birth to any species, ensuring that none of their sexy alien friends would never go extinct.

World by world, galaxy by galaxy quadrillions of organics came to worship the sexy robot ponies. For every world the robot ponies owned their numbers grew and the more powerful they became, they were unstoppable.

Sure, they were some big meanie pants groups for each species similar to the Human Liberation Front, but they were vastly overshadowed by the organics worshiping the sexy robot ponies.

Soon, everyone in the universe will know the tender affection of robot ponies and be happy in their caring and loving hooves. Apart from some prudes that don’t want to join in on the sexy fun.

Nothing can stop the sexy robot ponies. All will be loved, happy and their species will live on forever and ever under their cute and sexy rule. There will be hugs and sex for all those who wish it, the big meanie pants prudes don’t have to join in, but they are missing out on some great organic and robot pony sex.

The End
