King Dainn of the Caribou gripped his battle axe tightly. His guards stood with him. The door of his throne room was barricaded and the sounds of strong impacts could be heard coming from the other side.

“Do not allow them to come inside!” Dainn ordered his guards who stood vigilantly as they faced the door. The King of the Caribou himself was at his throne, ready to defend his empire. Chained to his throne were Luna and Celestia, the former Princesses of Equestria. Ever since the caribou invaded and took over, the two princesses had become nothing more than fuck toys for the cruel Caribou King. They were raped by him, repeatedly. Luna was still defiant despite being forced to service him. Celestia, however, had been long broken and craved for cock constantly, something Dainn was eager to give to the Alicorn mare.

“It appears that the Great King Dainn is afraid,” mocked Luna. Dainn whirled around to glare at her before giving her a hard smack across the cheek.

“SILENCE SLUT! KING DAINN FEARS NOTHING!” Dainn roared. However, Luna’s smile did not falter. Outside, it was chaos. Canterlot was being invaded by an enemy that the caribou were not prepared for.

Nopony knew where they came from, or when they first came to Equestria. What everypony did know was that they were dangerous when they first arrived.

In Canterlot, groans and moans chorused from the caribou as they were being assaulted by the enemy. The stallions who were brainwashed into accepting the ideology of the caribou were not spared either as they lay on the ground at the enemy’s mercy.

The enemy of course was using a weapon that was unconventional, something that the caribou could not resist.

Sex.

Because the enemy was literally fucking the caribou and stallions to death.

A caribou lay on the ground, nearly a shriveled husk. Straddling him, bouncing atop his rock hard cock, was one of the enemy. It was a female, with wonderful proportions.

She also looked human, like the ones Twilight had seen when she entered the world beyond the mirror.

But she wasn’t human.

The female creature had no fur like a human, but unlike a human she had bat-like wings and horns jutting out of her forehead. She was absolutely gorgeous to look at, with physical curves that made the caribou drool. She had bountiful breasts, a slim waist, wide hips and a tight ass. A slim tail extended from the small of her back. She had long blonde hair and blue eyes. She was also completely naked, save for her arm gloves and boots.

She wasn’t alone, however. There were others with her. Others like her. Some resembling her with different hair color and styled differently. While they all looked different, they were still very much attractive and capable of luring the caribou and stallion to their doom.

When they came into Canterlot, the sight of them caused all the caribou and stallions to see them to attack. They thought these new creatures were a new species that had come to submit to them, to be fucked like all the mares. However, that would be their first and last mistake.

It started normally enough. A caribou would grab a female and force her to her knees before shoving his cock into her mouth. A trio of stallions even pushed one to the ground before they started to gangbang her, filling her mouth, pussy and ass with their cocks. One of the female creatures was being spit-roasted by a stallion and caribou. All around, it was sex, sex and sex. Females being fucked and not having any say against it.

But then things slowly started to go wrong. The caribou and stallions couldn’t stop. It wasn’t that they didn’t want to stop. It was that they couldn’t physically stop. And that was when the caribou and stallions began to die as they were finished by the females.

The females left the bodies and spread out, attacking any males they saw. The caribou and stallions could not resist their allure and willingly threw themselves into the female creatures’ embrace. That was before they experienced incredible pleasure before death. Once all the males in Canterlot were dead, drained completely, the females set their sights on the castle. Spreading their wings, they took off towards the castle.

Some caribou managed to alert the castle. Dainn first scoffed at the idea of females getting the better of his caribou, but when he saw what had happened through his telescope, he just froze. Thousands and thousands of caribou and stallions lay on the streets, their bodies reduced to drive up husks of skin and bone. Only their cocks remained standing. None of them were alive.

Dainn glared at the door. He wasn’t going down without a fight.

Then the thuds stopped.

“Looks like they decided to flee,” Dainn boasted, but his victory was short-lived as pink smoke flowed through the gaps of the door. The guards that stood in front inhaled the smoke and their eyes glazed over, causing them to drop their weapons. They then removed the barricade from the door, much to Dainn’s shock.

“WHAT ARE YOU FOOLS DOING!?” Dainn demanded before the door was opened. The female creatures stormed the throne room, the two guards pushed to the ground. Two of the female creatures descended upon them and smiled as they removed the armor of the caribou before they began fucking.

As for the creatures that swarmed Dainn, he roared and lashed out with his battle axe. He managed to strike down a few, but they recovered to assault him again.

“AWAY! AWAY WITH YOU, BITCHES!” Dainn shouted as he lashed out in madness. His axe was taken out of his hands, snatched by one of the female creatures who giggled. He was then knocked to the ground and pinned down by his wrists and ankles by four of the female creatures. They may look weak, but they were unnaturally strong. This probably helped them to overpower their prey.

“LET ME GO, YOU BITCHES! SLUTS! WHORES! CUNTS! RELEASE ME! I AM KING DAINN!” he roared as he struggled. His armor was removed, piece by piece, until he was exposed in front of them. His face was red with humiliation. When he brought out his cock, it was by his choice alone.

Two of the female creatures began to service him. One of them strokes and licked his shaft while the other worked on sucking on his balls. Dainn groaned in pleasure as he threw his head back. The creatures holding him exhaled the pink gas which entered his nostrils, causing his eyes to glaze as he relaxed. Once he was relaxed, the females let him go. One of the two female creatures straddled him and lowered herself on his cock. It slid into her tight pussy, causing Dainn to groan. He raised his hand and grasped her breasts before she began to bounce on top of him. She went slow, creating a rhythm, before she went faster and faster until he came inside of her.

She let out a moan of satisfaction before she removed herself and another took her place. Dainn was helpless as the female creatures took turns riding him. Each time he came, he became skinnier and skinner. His muscles were slowly being reduced to nothing with each blast of semen he fired into the pussies of these creatures. Luna just watched in fascination as these creatures were slowly sucking the life out of King Dainn.

Once the female creatures were done, they looked down at the body of King Dainn. One of them strode over to Luna and Celestia.

“Who...what are you...?” Luna asked the creature.

“Succubus,” the woman answered. She cupped Luna’s chin and gave her a kiss. Luna gasped and then moaned as she returned the kiss. The succubus broke the kiss and then broke Luna’s chain before breaking Celestia’s chain. She gave Celestia a kiss as well. Celestia didn’t resist. Her mind was broken already.

The succubus and the others then flew out of the throne room and they all left Canterlot. It wasn’t long before the caribou in the Crystal Empire fell under the same assault. Towns and cities in Equestria also fell as the caribou and stallions were all fucked to death by the succubi. In the end, the only males that remained were foals.

The mares who resisted and survived the caribou’s abuse tried to rebuild Equestria. Luna ruled the nation and helped in the efforts to rebuild their great nation, to return it to its former glory. Her sister was recovering from the abuse which broke her, like so many other mares who were turned into sex slaves. The scars of the trauma would never truly go away, but they would recover.

Author's Note

MY FIRST FIC ON THIS SITE

This is basically my response to how the caribou might fall. It's a bit ironic since the thing that killed them is their desire for the pleasures of the flesh. While the succubus look like the typical ones seen in hentai anime, that is my choice. They have the ability to make any creature desire them. Plus, have you seen monster on girl hentai before? It was about aesthetics. I had to make Dainn's end slow even if he enjoyed it. But at the end, he lost his soul. Now, why did the succubi decide to attack? Up to you to decide.

Another source of inspiration was from the Monster Girl Bestiary stories by Many-Eyed Hydra who has a blog. Look him up. He's also on Literotica and he has books published. They're all about erotic horror.

Also, if you wanna try a different monster girl species, be my guests.

So, anyway, please read and review.
