An Infestation in the Herd

Part 19

For FlimFlamFun5

By Draconicon

The night of the orgy came. On the night of the new moon, when there was no need for Luna to go flying through the sky, it was said that the sisters and their most loyal attendants met for a discussion on the politics and the decisions that needed to be made about the realm as a whole. The rest of the kingdom had no idea of just how debauched those 'discussions' became on a general rule, with most of those invited passed out on cum, pussy juice, and perhaps more depending on just how extreme the princesses were feeling that night.

But tonight, it would be different. The Hive would be there, and in force. There were multiple couples that were invited to the party that were completely infested, and there were no couples that didn't have at least one partner completely taken over by the Hive. The mix of Day Guards and Night Guards at the party would be all but taken over, as well, ensuring that the Hive operated in security and secrecy. Nobody would know that it was a night of infestation, a grand coup over the royal powers of Equestria, until it was already over and done. Perhaps not even then, if they did their jobs right.

Moonlight Thunder walked beside Princess Luna. With Lancer officially 'supplanted' as her preferred lover - at least, in the eyes of those that hadn't been infested by her yet - he was a perfect choice to bring along to the party. Celestia had heard the rumors, and most ponies that were in the know of the sisters' preferences knew that she would want to try out the one that had captured Luna's fascination. He had every reason to be there.

The Hive ensured that.

The Hive would have the Princess of the Sun by morning.

As they walked down the hall, they both would pause here and there, glancing at the ponies they passed. Here, a servant looked Luna in the eye and nodded. There, a soldier looked at Moonlight and stomped his hoof three times. Signals, little pass-codes that they had developed to remind each other who was a host and who was not.

After all, the Hive was powerful. It was not omniscient.

Other conspirators might have talked to each other to ease the tension of what they were about to do. The Hive and its hosts did not. The parasites seldom felt emotions the way that their hosts did. Anxiety, nervousness, all those things were more suited to the ponies than to the ones that controlled them. As a result, there was no need for banter to bring down the worries. The only reason such a thing would come about would be to blend in.

And there was no need for that. Two ponies of every three that they saw gave the code, the signal, the indication that they were already possessed and infested. They would soon be able to drop the pretense of being 'normal' ponies, and go back to just living as the parasites that they were.

They traveled through the palace for some time, killing the minutes until the midnight hour in which they would be required to be at the party. Luna said nothing, though the host's body was dripping. Moonlight Thunder said nothing, either, though his shaft throbbed out of his sheath, pushing forward and out.

It wasn't in anticipation, of course. It was more along the lines of someone checking their weapon, priming it, ensuring that it was ready and willing from the start. His balls churned between his hind legs, sending what should have been rutting insanity to his mind, but the parasite within him kept that to a minimum. There was no reason for the Stud of the Hive to be anything less than focused at this point. They were going to use him, weaponize him against the Princess of the Sun. He needed everything that he could bring to bear, and the parasite primed him, controlled him, wielded him for the Hive's benefit. That was all there was to it, and all there needed to be.

They finally reached the door to the private room. Luna's horn glowed as she brought her magic to bear, blasting the little hole in the center of the massive stone door. The blue light glowed for a moment, and the door unlatched. Moonlight Thunder opened the door with a hoof, looking inside.

The other nobles were already there, though Celestia was nowhere to be seen. He imagined - or rather, the Hive did - that she would be there later, when the rest of the party-goers had all arrived and she could take her pick of partners. He pushed the door open the rest of the way, his parasite already dragging him down into that proper role as a princess's companion. He bowed his head, even though he was the more senior host, and stepped to the side to allow her to step through the door.

All voices stopped, some sooner than others. The infested hosts stopped together, seeing Luna, while the uninfested took a second to realize that she was there. It was a moment of stupidity, of weakness, but the uninfested were too eager for the festivities to notice.

Luna stepped through, her austere nature as a general rule meaning that there was less chance that the detached 'personality' of the parasite would be noticed. She looked down at the other party-goers, and almost as if remembering what she was there for, put on a small smile.

"Let everyone enjoy themselves," the Princess of the Moon declared. "This is a celebration. Let there be celebrating."

There was a small cheer at that, though the ponies in the great hall were quieter than they had been, almost as if they were a little afraid. Perhaps they should be. Even though the memory of Luna's lusts and hungers had been mostly suppressed by the parasite inside him, Moonlight Thunder still vaguely remembered the aches that had come afterward, the reminders of just how powerful and needy one princess was. Her past partners probably remembered far more than he did.

Yet, despite those aches and pains, he didn't feel fear. Nor anxiety. Nor worries. Nor guilt. He felt...confident. There were more than enough Hive members here to take her down, and he was the best of them. So long as they were able to pile on, to keep giving her more and more of what she needed, she would eventually fall before them.

Luna had already moved on, the parasite knowing what she was supposed to be doing to keep her cover, and Moonlight moved to the buffet line. There were already some ponies that were starting to wobble, and not just because of being drunk. He walked down the table, eventually finding one of the servant stallions. He leaned in a bit.

"A dripping rod."

"A slippery tail."

Another pair of codewords. He nodded.

"Are we dosing everything?"

"Everything that we can. Running low, though."

"Do you need more?"

"Badly."

"Around the corner."

Moonlight had time, and he was dripping enough that he could make a contribution. They walked casually around the table, making it look like the commoner was just trying to fit in with the servants rather than the higher-ranking nobles around him. It was safer this way; while he could have gone around using different signals and codewords to try and find out which were which, he could end up approaching a pair that were married but not both infested, and that would give the game away early.

Once they were fucking, rutting, changing each other, then there would be opportunities to start talking to everyone. Until then, he had to play it safe.

He and the stallion servant made their way to the corner of the room and into the side, hidden corridor that the servants used to bring food and drink into the chamber. They moved just out of sight, with Moonlight Thunder glancing back at the chamber to make sure that they weren't followed, and then set to work.

His parasite pressed down on his prostate, sending a shiver of pleasure through him that didn't quite show on his face. The servant held a glass just under his shaft, allowing the silvery pre-cum to dribble into it.

There were no comments made between them. Observations and quips were the realm of the normal ponies. The infested didn't have the need to make comments about everything around them, questioning and making remarks about everything in their lives. They just interacted and got on with it.

Drip, drop, drip, drop. Moonlight felt every dribble through his shaft, the sensation of oozing and leaking having never been so powerful before. The longer that he remained bonded and infested with the parasite within him, the more sensitive and sexual his body became. It was an odd mix of physical attachment and physical detachment, as he was not in control and could not feel what his parasite didn't want him to feel, but at the same time, everything that he did feel was just completely overwhelming, hitting him harder and harder with each new thing.

It was rather wonderful in its own way, if rather difficult to deal with.

He didn't moan when his parasite told him that he was done, nor did he complain about the blue balls that he was already getting. Instead, he just slapped his cock up against his belly to signify that was all the pre-cum that the other stallion was getting, and the other host pulled the cup back, holding it carefully and swilling it around. One might have thought that he would be about to drink it, but no. He was merely checking to make sure that it would settle.

"This should be enough."

"For now."

"For now," the servant agreed.

"You'll have to find another or milk yourself for more later."

"Understood."

There was no need to explain further. All other parasite-infested hosts knew the plan. They had passed that between them, tail to tail, well before the party had started. The way to take Celestia was entirely based on her needs.

Fuck her.

'Clean' her with enemas of pre-harvested corrupt cum.

Fuck her again.

Drug her with the goods.

Clean her again.

Fuck her again.

And then, when she was finally completely out of it, or at least, as out of it as she could be without being rutted right into the ground and tied up, they would put an egg in her, telling her that it was just a toy that would make her feel even better. That was the only way that they could get it in her, it had been decided. Celestia would be too powerful, otherwise, and they needed her to take it without question.

Once the egg was inside, it would hatch. That would be the end, they hoped. They would have to keep feeding her, drugging her, making her drunk and horny and too distracted to think while the parasite attached itself inside and fought with her will. Luna had almost overwhelmed the parasite, and they couldn't risk that happening again.

The only worry was whether the parasite itself would be able to hatch inside the mare rather than outside. That was different to all the other infestations that they had done, but they didn't have a choice. Anything obvious from outside would pull the powerful Princess of the Sun's attention on them, and that would be the end of the coup.

This, or nothing. That was the plan.

He was just returning to the buffet table when the windows at the far end of the great hall illuminated with brilliant sunlight. It was impossible, considering it was midnight, but that did not stop the power of the Princess of the Sun from displaying itself. The windows opened, and the white-furred, winged mare flew in from outside. She tossed her head back, her rainbow mane fluttering down over her back.

"My loving subjects. It has been too long..."

She smiled benevolently around the room, though not without the hunger that he finally noticed. There was a need there, a desperate need for the real purposes of the party.

And Luna did not disappoint. No sooner had Celestia given her greetings than her sister stepped forward. Moonlight Thunder followed her, standing just behind the tall mare and looking up at the even taller one.

"My sister. May I present my latest acquisition?" Luna said.

"You mean acquaintance, my dear, I'm sure."

"He is quite eager to be mine. And ours, even."

"Is that so? And what is your name, little stallion?" Celestia asked.

"Moonlight Thunder."

"And are you partnered?"

"Technically."

"Oh? Is she here?"

"No...she wanted me to come here and enjoy myself, and then come back and tell her about it. She likes to hear about what her stud does."

It was a lie, a blanket lie compared to what they used to do, but that was fine. All hosts got used to lying, and this was no different to what he had done in other villages. All the relationship and love that he had shared with Azure Breeze had been left behind, nothing more than a memory compared to what the Hive offered him and the other infested. They were all part of a group, and if a different lifestyle suited the group, then they would pivot to that rather than regret the loss of their old one.

Celestia seemed to like his answer, too, as she smiled and slowly turned in place. He had a good view of her hips and 'plot' for a moment before she turned all the way around, lifting her tail and showing off.

He was already completely prepared for his duty as a stud, but if he hadn't been, that view would have readied him in a second. That puffy donut of a hole stood over a slit that was clenching madly, dripping down her hind legs and giving off fumes of arousal. The utter control that this mare had to not show any of that on her face was legendary, and made him think that she would be perfect as a host.

If she could be overwhelmed.

"Let the orgy begin," Celestia called out. "And you...put it in me, now."

Moonlight Thunder had no reasons to hold back, though there was a hint of that fear that his time with Luna had prompted. He glanced out of the corner of his eye at Luna, the other sister giving him a nod. There was no holding back now. He had to get started.

And so he did.

He lunged forward, shoving his cock past Celestia's pussy lips, and he was inside of her almost immediately. She squelched from how wet she was, her inner walls already gripping him tight, and the parasite deep down inside him started pushing him to squirt pre-cum, flooding her inner walls, making sure that she was even wetter.

Drug her.

Dose her.

Make her hornier.

Make her want it more.

Even as he started thrusting, she pushed back, but it wasn't the drugged, moaning hip thrusts that he was used to from all the other bitches that he'd studded over the course of his time as an infested drone. No, this was someone that wanted it, that needed to be fucked, and who was taking what they needed to get that.

This was someone that was utterly in control of themselves, and shameless about getting what they needed.

In, out, in, out, and he was going balls deep for the first time with ease. There was no holding back here, no need to. She was bigger than him, able to take every inch of his cock with ease. She moaned out loud, her head lowering towards the ground, but she didn't give in. She didn't just go quiet or let him rut away. No, she pushed back, she took him as far as she could take him, making his balls swing forward and slap against her clit.

"Mmm...I can see why my sister likes you..."

He didn't pause, didn't respond. He pulled her hips closer with his front hooves, doing everything in his power to keep the rut going hard. The parasite was already weighing how long to wait for the first orgasm, how long they dared wait with their stamina. The fact that they'd have to go multiple rounds wasn't in question; it was just a matter of how long they'd make each round, and how long they waited between them to do it again so that they could recharge.

The main point was to make it messy. His balls were going into overdrive, producing cum and pre-cum in thick, extensive measure and blowing it right down his cock and into her pussy. Every blast was making it easier to bottom out, making each thrust that much faster and more pleasurable, but more, it was providing more and more of that aphrodisiac dose that would - hopefully - make her more pliable, more eager.

In, out, in, out...

He didn't pant, but she did. Moonlight Thunder didn't take it as a sign that she was weakening, though, just that she was indulging herself, having fun, allowing the pleasure of the moment to settle in. She wasn't going to break that easily, even as her juices and his oozed out in equal measure from between her hind legs. She lowered her front hooves, stretching out, pushing her rump back towards him.

He took it as the invitation it was and hammered at her harder, faster. The pleasure of her inner walls around his cock was as good as he could imagine, but he knew that it was not for him to enjoy. He had a task. Hump, thrust, grind, bringing her pleasure and -

"OOOOOH!"

Celestia's moan broke out over the room, accompanied by many others that were doing the same. He looked around momentarily, spotting several couples where the top was someone that was infested and the bottom was not, and vice versa. The couples had been swapped in many cases, with some of the nobles getting new partners, and some of the infested making sure that they were getting with those that didn't have a parasite yet. There were some couples that had the same bored, blank face that he was trying to keep off his own muzzle, knowing how much of a dead giveaway it was.

But the whole room was filled with rutting couples, some of which were having the time of their lives, and most of which were merely doing a task. In that moment, he saw the difference between them...

And he was fine with that.

"Oooh...oooh..."

Celestia moaned under him, and he allowed himself a climax. A thick, gooey one, one that would take a while to clean out. Pulse, pulse, throb. His seed splattered through her insides, the flared head of his cock ensuring that it went deep and stayed deep. Even with the flare trying to keep it all in, though, he could feel some of the slime pushing back, trying to slide out, trying to drip out past his cock.

It was warm, naughty, and a little bit filthy. In the past, uninfested, he would have loved it. In the past, he would have been eager to tease his mare bitch about how much she loved it from how much her inner walls clamped down.

Now, he just saw it as a job partially done, and they needed to do more. Celestia shivered, pushing at him with her tail.

"Time for a cleaning...but then you can go again...if you can."

"Mmm-hmm."

He pulled back slowly, taking his time to really drag his cock along her inner walls. Despite the fact that he had just cum, he was still hard. Rock hard, as a matter of fact, and he could feel that the head of his cock was still rather sensitive. The flared edges of his cock head dragged along her inner walls, stimulating her further, ensuring that she was going to be primed and ready for the next bit.

POP!

The head of his shaft left her, and her pussy lips gaped open for a moment. Despite their size difference, he was still particularly well-endowed, and that meant that there was going to be an effect of him ramming in that hard. She gaped, and dripped. Oh, how she dripped with the slime that he had left behind in there.

"Mmph. Cleaner!"

She called out, and one of the infested servants came forward. They held a syringe filled with clear fluid, one that looked like water and soap together. In reality, it was more of the harvested, corrupted fluids of the various Hive members, ranging from some that Moonlight Thunder had contributed to some harvested mare juices, all jumbled together to create the most corruptive, arousing concoction that they could.

The mares that had it injected in them before had almost cum instantly, but they knew that wouldn't be the case here. They'd need to do this over and over again to wear Celestia down, but eventually...hopefully...

Celestia spread her hind legs further, allowing the rubber-tipped end of the syringe inside her. The pony holding it pushed down, and she shivered, her asshole puckering hard as she was filled to the brim with the slime inside.

It didn't take long for it to fill her up, and she squatted down as soon as the syringe was removed, oozing, dripping. She pushed it all out, making a puddle of stallion cum and more between her hooves, almost as if she was pissing it all out, though far slower and far more erotically than that. Bit by bit, it fell from her, staining her, soaking her.

But then...

Then she was all the more eager. She looked back at him, her eyes wild, her face twisted in utter need.

"More," she whispered.

Moonlight Thunder didn't sigh, though he wanted to. It was time to get back to work.

The rutting continued for four hours, and there was no sign of the mare slowing down. If anything, the aphrodisiacs seemed to give her more energy, more power than she had before, and she kept pushing for more. She wanted a cock in her ass, too. She wanted a cock in her ass and in her mouth at the same time. She wanted a mare under her to lick her pussy while she was getting fucked in the ass and mouth. She wanted a stallion to back his ass up to her face to rim him while she was getting fucked.

Everything she wanted, she got, and between the different rounds, she was fed and watered with as much of the drugged food and water as they could shove down her throat.

Moonlight Thunder watched dispassionately when he allowed other stallions to step forward and do their work, knowing that he needed the rest and not offended by it. More, he was studying her, seeing how long it would take. Four hours of fucking was not uncommon, but it was still intense.

The rest of the room had long since gone quiet, though not still. The majority of the herd had been converted, with just two or three prudes that were holding out. They were being wined and dined by those in the Hive that wanted to take them in, but nobody was pushing that hard with Celestia still somewhat sober.

They needed her.

They needed to bring her down.

Finally, five hours in, as one of the stallions pulled out of her pucker and groaned in utter satisfaction, she nearly collapsed. She slumped forward, her front legs no longer supporting her, her asshole and her pussy alike oozing so much cum and slime that she looked like some alley-mare that had been left by her John rather than the Princess of the Sun. She moaned, her holes puckering for more.

It was time.

This had to be it.

He stepped forward, taking one of the eggs offered by someone else in the crowd. They were all ready for this moment. Luna stepped around to face her sister while he walked up behind her.

"Sister. We have something more for you."

"Mmm?"

"A toy."

"Heh...what would a toy do for me?"

"A lot. An egg-shaped toy, one to carry around. Pregnant without being pregnant."

"Oooooh...that could be fun..."

"Just relax...and let it in..."

There was no way that Celestia would have fallen for that in another time, another place, but after cumming her brains out for five hours straight, after being drugged, after being rutted, after having an entire bottle of berry-wine shoved up her ass as an enema at one point, there was no way that she had the sobriety to see the trap before her. All she did was lift her tail further, showing off her cum-stained pucker.

Moonlight Thunder pushed the parasite's egg against her hole without guilt or shame. It was already cracking as he nudged it forward with his hoof, and then...he waited. They all waited, and even the parasites couldn't quite keep the anticipation off their hosts' faces.

At first, nothing happened. Sure, Celestia continued to moan and she didn't get back up, but there was none of the stillness, the limpness, or anything else that had happened to the other hosts. Instead, she just stood there, giggling, smiling, bent over and moaning. Her holes clenched, her juices flowed -

Squirt.

And she came again, though with more of a grunt than a full moan. She squirted from both holes, and the hosts wondered if they saw egg slime there, or just the slime that they had already pushed inside.

The giggles finally stopped. Instead, Celestia groaned, tilting her head one way, then the other. She looked dizzy, out of it, confused. She shook her head, stared straight ahead, and then shook her head again.

It was happening, they realized. It was finally happening.

Moonlight Thunder watched, waiting, seeing if he would be needed. If he had to rise up and mount her again, fuck her into the ground while the parasite took control. His cock rose up, ready to do just that -

But then the same thing that had happened to Luna happened to Celestia. She started urinating.

"Ah!"

She gasped, the white mare's eyes going wide as the slow but gradually speeding up flow between her legs continued. It ran white, sliding down white fur, and then squirting down to the floor. Nobody else laughed, nobody else stared for any more reason than fascination at the fact that she was doing it. Her face went from ashamed and embarrassed to an expression of pleasure, and then finally something completely blank.

The fire in her eyes remained, but that was slowly changing, too, shifting, becoming something else. They were slowly warping, slowly dulling, becoming something less focused and more...

More relaxed.

More subdued.

The hosts waited, watching as her holes puckered and clenched. Bit by bit, her asshole opened. A wave of cum and slime oozed out, followed by a hint of shell. Then another, a bigger piece, and another past that. The crunchy pieces hit the floor, breaking the silence that had fallen on the great hall.

The hiss of her urine hitting the floor finally stopped, turning into more of a drip-drop as the last bit of her bladder's contents stopped flowing. She had been purged of most of the drugs at that point, then, according to what they had learned from Luna. The Princess of the Sun remained in the bent-over position for a moment more...

And then she stood up.

There was none of the shaky hoof-fumbling that one might have expected from someone so drunk or distracted. Instead, she got to her hooves with a grace that belied her situation and the mess on the floor. One steady step, then another, lifted her back to all fours. She turned her head left, slowly, gradually, until it could turn no more, and then did the same as she turned to the right. She lifted it up, then down, almost like someone learning how to do it for the first time.

The hosts knew that was precisely what was happening. Celestia's host was learning how her body worked, and how it could put it to use.

It turned, looking down at them. Luna looked back, her horn at the ready.

But there was need. Celestia slowly turned around, exposing her fat rump, and the hole spread, a tail pushing out. No statement, no requirement for information. If anything, the tendril was desperate enough, asking for information, asking to be filled in.

Luna gave it.

As soon as the connection was made, Celestia opened her mouth. Moonlight Thunder was ready to stop her from shouting, but rather than demanding an explanation, or pleading with her subjects to run, she said something entirely different.

"Seize free ones. Break them."

That was all that she said, and it was all that she needed to say. The swarm of infested ponies fell on the ones that were yet to be broken, pinning them down with four or five ponies to a free mare or free stallion. The others screamed and whinnied in utter shock at what was happening around them, even as the servants brought out more syringes, more bottles of berry-wine.

The infestation was going to happen, whether the ponies wanted it or not. The Hive had waited long enough.

As the rutting went on in the background, as complaining shouts and screams turned to desperate moans, Moonlight Thunder looked back to Princess Celestia. The more that the parasite within her learned from the sister-host, the more in-control it seemed. The Hive did not have a king or queen, but they could have those that called the shots, that were allowed to make decisions on the part of the Hive when there was not a consensus to be reached with the overall group. Moonlight Thunder had been one such pony, directing the conversion of others for some time.

Celestia, it seemed, would be another, one to command the overall infestation of the kingdom. Not as a host having free will, but like Luna, being rewarded for being good at making decisions, at finding ways to get what they wanted, and then giving it to the rest of the Hive. Her mind would be useful, her body moreso, and her power more than that.

They had the Princesses, now. There were few forces in the land that were able to stand against one of the Princesses, let alone both. Once they had this one, once they had Celestia fully informed and were able to take down the Changelings, bringing them into the fold...

Well, that would mean the end of a free Equestria. Everyone would be brought into the Hive. Everyone would further the goals of the parasites, to breed and create more and more hosts, to allow for a world where everything worked the way that they wanted, and never to be shifted or messed up by free will.

Moonlight Thunder paid homage to the moment, knowing that it was the end of all freedom. There would be no turning back from this point. There would never, ever be an Equestria where those uninfested would have a chance to turn back the clock all the way to no infestations. With the power of the Princesses, the Hive was there to stay. It was just a matter of how much more they took.

The parasites within, Moonlight Thunder knew, wanted it all. They had made a deal with the Changelings, and then had gone back on it. They had held back at times, but never for long. They were an expanding species, constantly expanding, growing, getting stronger and needier the more that they had. They couldn't stop.

And they wouldn't.

The End

Summary: The orgy of Celestia and Luna begins, and so does the corruption of the Princess of the Sun.
