An Infestation in the Herd

Part 1

For flimflamfun5

By Draconicon

Moonlight Thunder, an earth pony farmer who lived halfway between Ponyville and Canterlot, was in the middle of dragging the goods from the far edge of the farm to his barn when he had a most curious encounter.

The brown-colored stallion, with 'socks' on his legs of black fuzz, looked down at the little mass of goo further down the dirt path that ran between his fields. He huffed slightly, chewing on the end of a piece of hay as he debated whether he should drag his cart in a different direction. He'd just cleaned the wheels, and had taken a lot of care to keep from getting them dirty while dragging them around the mucky parts of the field. That stuff looked like it'd slime up the axle something terrible.

At the same time, he knew better than to try and change direction now. All the lanes between the fields were one way, just big enough to get the cart down, and the next turn was past the goo. If he was gonna take a different route, he'd have had to have turned about a hundred feet back.

Tarnation...

He grumbled, clenching his teeth on the edge of the hay as he grumpily pulled the cart forward.

If so much as a bit gets on the wheels...

He slowed as he approached the puddle. It wasn't quite wide enough to risk the wheels, after all, but the gunk looked absolutely foul. Bright green, it seemed to jiggle as he came close, wiggling like some of the wife's jell-o. It looked like something someone sneezed out, and...was there something moving in there?

Hoping the rain would wash it away later, he pulled the cart forward that little bit further. He stepped on one side of the puddle, then a bit further, then -

Pinch!

"GAH!"

Moonlight Thunder just about jumped out of his skin, whipping his head around to see what in the world had just done that. There was nothing on the road behind him that coulda snuck up and got him, and he hadn't see anything in the puddle. Nothing for real, anyway; there couldn't have been any -

But there was. Something green had grabbed his black tail as it had dipped down, pinching it between two strange foreclaws. The thing itself was almost like a crab, except that it was long rather than wide, and it was using its forelegs to drag itself up his tail, and it was moving a lot faster than it had any right to.

He couldn't even buck it off. The harness had him stuck, bound to the cart, and the cart itself was too close for him to rear back and try and kick at it. All he could do was stomp and shake his ass back and forth, trying to wiggle the little critter off him so that he could crush it beneath a hoof.

"Get off, you damn thing! Get offa me before I - Nnngh!"

It had climbed all the way up his tail, and now, it was pressing right between his rump cheeks. The oddly smooth 'face' it had was wiggling back and forth against his pucker, almost like it was trying to force it open. He whinnied loudly, but...but...

But there was something odd about it, something that was making his hole almost itch. He grunted, shaking his head, trying to keep the feeling at bay, but try as he might, there was nothing he could do. It was just getting worse and worse, his hole puckering hard, his eyes rolling back, and his cock slowly starting to spill out of his sheath.

"T-tarnation..."

He huffed, having not felt this aroused since the last time that his mare went into heat. The feeling was running through his cock and balls all the way back to his ass, and his hole started to relax, opening up a bit. He'd felt it happen before, the few times that he'd bottomed for a neighbor for a favor, but...fuck...

He huffed, his tail flagging up before he could stop it, his body fighting his brain as he felt the urge to feel something inside of him. The more that the slime from the creature rubbed against his ass, the more he wanted it. The more he needed it.

The weird little critter pushed against his hole again, and this time, the tip of it slid right in. He gasped, arching his back, his cock completely hard and dripping from the end of his sheath, slowly grinding and thudding against his belly as he felt the creature sliding in deeper, further into his hole.

It was no longer so thick, only a long tendril that hung out through his pucker. His tongue hung out of his mouth as he felt the pleasure rising, his ability to think diminishing. He started clenching at his muscles, making his cock rise and fall, thudding it against his belly in equine masturbation. Up, down, up, down, even as the thing in his ass continued to move and squirm and grind against his little button inside.

It almost felt like his ass was slurping up that tendril still hanging out, too, sucking on it like a piece of pasta. His eyes were rolling back in his head, his body shaking from head to hooves at the weird, heated feeling that was filling him up from below. His cock was hard, stiff, throbbing, dripping, the flare starting to grow at the tip as the critter started to settle into his ass properly. It brought all those legs around and -

Clench. He whinnied as he felt something latch onto his prostate, digging into the inner walls of his ass. His eyes were rolled so far back that he couldn't see anything anymore, and his cock throbbed and -

"NNNNNGH!"

Moonlight Thunder whinnied as he came, squirting his load all over the ground right then and there. His body shook, but the spasms of pleasure continued to fill him, running through him, leaving him trembling as his cock kept jerking, kept squirting, kept flailing all about.

He almost wanted to collapse, his mind on anything but the thing in his ass, but he didn't. Something...something pushed him to stay upright. Something pushed him to stay hard and horny. Something...

Something was in his head.

Moonlight Thunder huffed and puffed, staring straight ahead as little ripples of sensation echoed up and down his spine, bubbling and pushing out from his back along his sides, and then over his neck, slowly moving further and further up towards his skull. It was a strange, twisted, very different feeling, almost like he wasn't entirely himself anymore.

His head swayed left, then right, then left again, lazy, slow, tired. The stallion kept staring ahead, his ability to think impaired, his mind distracted by all the need coming from between his hind legs.

The feeling in his spine reached his skull at the same time that another clench happened right against his prostate. Moonlight Thunder moaned again, his head dropping down, and shortly after, he went quiet. The pulsing between his prostate and his skull were almost completely in sync, and his cock throbbed obediently to the feeling that it provoked, bouncing up, slapping his belly, and then pointing down again.

The stallion went still, his eyes straight ahead, his thoughts paralyzed in place. Not rendered dumb, not unthinking, but obedient. Obedient, directed, focused. Yes. That was right. Something else was giving him what he needed, something else was telling him what was right.

And that wasn't the cart of food. It was...something...

There was a rustling, searching feeling in his head, almost like there were fingers darting through his memories, something picking at them and pulling them out and putting them back again. Moonlight - just Moonlight, now, no need for Thunder, no need for the second name for someone like him - kept staring straight ahead as the different images popped up in front of his eyes. A picture of his wife, a mare as white as he was brown. Then there were the friends in the village, mostly other stallions, other men that he spent time with, other people that he talked his trade with.

And then there was the neighbor down the road, another stallion, one that was burly, thick in the shoulders, wide of hip, and who had shared a fair bit of 'fun' with him in the past.

There was a click of sorts, a feeling of completion, and Moonlight stood up straight again. He felt an urge to undo the harness, and he started doing it, slowly, mechanically, precisely. Every move was just as much as was needed, turning his head to undo one strap on his left, and then doing the same on his right. The leather straps came loose, and he stepped forward, leaving the cart behind.

Moonlight looked down at the puddle, and he realized that it had completely shrunk. There was almost none of the gunk left behind, save for a tiny bit that was oozing out from his pucker. He could just barely feel it dribbling down along his taint, running down to the balls just under them. It would dry soon, and then there would be no trace of it left, nothing that would reveal that he was infested.

There was a part of him that knew that this was wrong, that he should be panicking, that he should be afraid. Yet, there was nothing in him that was willing to go that far. He just turned, staring down the road, feeling what was needed. His plans for putting away the crops for the night had just disappeared on him, and it was like they had never been important in the slightest, as if all his priorities had just been rearranged.

His cock twitched under him, but it was slowly starting to shrink back into his sheath as the pulses that ran down from his prostate started to grow less and less regular. Instead, the pulses were coming from his head, something that...yes...yes...

Yes.

He was no longer Moonlight Thunder, a farmer. He was Moonlight, a part of the hive.

Clench. A reward, pleasure, bursting through him. The stallion moaned softly, thrusting his hips forward, one last squirt of pre shooting from his cock before it was fully dragged back into his sheath. Yes, he was a member of the hive, and that meant that part of his responsibilities were to spread the hive.

How did he know this? The creature didn't speak with him, but the urges came to him in thoughts, in brief images in his brain. It was as if the understanding was passed to him, and when he knew what he was supposed to accomplish, pleasure confirmed it. Pleasure that ran through his ass, through his cock, and then back again.

Spread the hive...

Moonlight realized that he was still walking, still making his way down the roads of the farm. He'd taken a turn along one of the intersections, bringing himself parallel to the main road that ran beside the farm. Where was he going?

Yes, he remembered now. There was a meeting with another farmer, his fuck-buddy, Ivory Flash. The white and black stallion was going to meet him halfway between their farms, and they were meant to go back to his place, to have some fun together. Neither of their wives knew what they did, really; they always excused it as a night out, having cider, enjoying each other's company, but they usually ended up rutting each other. They'd done it ever since they'd met each other as foals and grew up enough to understand what it meant.

Ivory had been a good friend for a long time. Tonight, he would become the second member of the hive.

Pulse. Another little clench, not as strong as the others. It wasn't a reward so much as it was communication, reminding him that he was on the right track, and telling him to keep it up. He was glad; he'd never been that smart, so getting it right this easily was a nice change.

The stallion glanced down the road at the farmhouse, considering heading down there to see if his wife was up. Then he decided against it. The wife would be there in the morning, and she'd be more likely to be interested in him at that point. Besides, if he managed to infect his old friend, then Ivory could start spreading it to his wife and family, and then they would have an even bigger hive.

The little pulse was all the confirmation he needed. He shouldn't get creative. He should just follow his objective. He was good with that.

#

Ivory was waiting for him at the usual spot, halfway between their respective farms beneath an old willow tree. The white and black stallion had been lying on his stomach, legs folded under him like a cat, and his friend chuckled at his approach.

"Looks like you finally made it. Get into some sort of squabble with the wife or something?"

"No, just needed to put a few things away."

In truth, it was more that he'd deliberately slowed down on the road. He felt something happening with the creature inside of him, something growing and bubbling in there, and he knew that it needed time to finish. He didn't know how or why he knew, but he felt that it was just about complete. They could have their fun, now.

He smiled, letting his cock drop from its sheath. Moonlight would have been surprised by that, but he'd felt that it was something that he could do now, and it dropped easily and fully from between his hind legs. Just like usual, the burly stallion he'd come to visit looked down, and just like usual, Ivory grinned.

"Well, now, looks like someone is happy to see me."

"He always is."

"Heh...been missing my ass, have you?"

"You know it's better."

"You're damn right it is."

The other farmer pushed himself to his hooves, slowly turning around and showing off his ass. It was a wide thing, well-muscled from all the farm work that the other stallion did, and as he flagged his tail to the side, he showed off a hell of a donut between the cheeks. It showed just how much use it had gone through, and Moonlight knew how easily it took dick.

Tonight, it was going to take that, and much more.

He walked forward with a slight waggle of his own hips, just enough to make his cock throb, make it sway, showing it off. His old friend chuckled, pushing his ass out a bit more.

"You plan on taking me here, then?"

"I was thinking further down the road...but why don't I give you a little tease..."

Moonlight lifted his front end, pressing his hooves down on either side of Ivory's haunches, and dragged his back half forward. His cock throbbed, spat pre-cum everywhere, but some of it managed to land on the other male's ass cheeks. He wiggled a bit further forward, grinding between the muscular cheeks, the flared tip of his cock finding that pucker.

Squirt, squirt, squirt.

He could have slid in then and there, but when he thought about it, there was no confirmation from the hive, no telling him that he was picking the right thing. So, he didn't. He just ground against that ass, squirting from time to time, staining it with his seed. It was a good way to spend time, at least, and it was definitely marking the other stallion.

Or...was it doing more?

He could feel Ivory shivering more than usual, trembling from the teasing, and that wasn't how the other male acted when they were having fun. At least, not until they were much deeper into it, when he was balls-deep in the other stallion and rutting him. He normally started out pretty stoic, making Moonlight work for that satisfaction. This time, he was just giving it up right off the bat.

Before he could try and figure it out, Moonlight felt his cock going soft again, and he knew that it was time to slide off. He pulled back, and he trotted up to stand beside the other, panting farmer.

"Why...why did you..."

"Stop?"

"That was feeling good. I don't know what it was, but..."

"Heh, call it a tease. We'll get to the main event later."

"Ugh...you ass."

"Up yours."

"What the hell do you think I'm begging for?!"

"Then start walking, Ivory. We need somewhere more private if we're gonna get down to business..."

That was all that he needed to say, and the white and black stallion was on the move. He followed, smiling to himself as he watched that ass twitching, knowing that he was doing the right thing, even if he didn't know what that was. He was part of the hive, and the hive would make sure that he stayed on the right path.

It didn't take long for Ivory's cock to start dropping as they walked along, nor did it take long for it to get hard. Shortly after, he could see the other stallion's hole twitching, puckering, begging for attention, and he started to piece it together. Just like how the creature had managed to make his ass horny with all the slime that it produced, somehow, it had changed him, making all his pre-cum do the same thing to Ivory's ass.

And the more time passed, the more that the other stallion showed how horny he was. He started to stumble, his hips starting to thrust without his consent, his cheeks burning with shame. Every so often, he would look over his shoulder, almost as if he was going to say something, only to turn his head around again and blush worse than ever.

There was no pretending that he wasn't staring at Moonlight's cock, either. It was rising once more with the help of the creature inside of him, and Moonlight smiled as if he was completely unaware of what was going on.

"Is everything okay?"

"Y-yeah, everything's...fine..."

"You sure?"

"S-sure I'm sure."

There was no way that Ivory was that fine, though. He was stumbling, shaking, his tail perpetually pushed off to the side as if he had lost all control of it. He wanted to bring it down, clearly, but his body was desperately in need of something inside of him. There was only so long that he would be able to hold out.

Hive will give you what you need, Ivory, he thought. You will be a good drone. A good helper to the hive. You will spread it, just like I am.

They kept walking, and Moonlight kept waiting. There was no need to hurry, no need to push. Sooner or later, his friend would give in, and then, they would have their fun.

And soon enough, he did. Ivory groaned as they passed by an old oak tree, finally turning off the road and darting for the big tree. He was halfway around it before he looked over his shoulder, staring at Moonlight. He nodded his head to the side, making it clear that the brown and black stallion was supposed to follow, and with a small chuckle, he did as he was asked.

By the time that he'd rounded the tree, the other pony had his ass up in the air, posing almost more like a dog than he was as a pony. He was panting, shaking it back and forth, his hole puckering and begging for something.

"Please...I can't...I can't keep waiting...I need something...something in me."

"Desperate, aren't you?"

"Nnngh...please..."

Ivory had never been this needy before, and if Moonlight had still been himself, there was no way that he would have been able to resist this display. It was so different from the strong horse that he had known for so long. Seeing anyone this desperate would have made him hard as a rock, but seeing his long-term fuck-buddy being like this? It made him feel like there was a magnet attached to his cock and it was dragging him straight ahead. He groaned under his breath, flexing his cock a few times, feeling it eagerly slapping against his belly.

The creature inside of him, the feeling of the hive, also seemed to approve. It pushed him along, clenching around the little pleasure button in his ass, telling him that it was time to fuck. He stepped forward, his hooves clip-clopping against the earth.

"Well, if you really want something inside of you..."

There was a small part of him that wanted to actually fuck his friend, but he knew better. The hive told him that there was something else, something better than needed to be put in there, and that he needed to focus on that. So, instead of rearing up on his hind legs, he lifted one foreleg, holding it out to the side.

Just as he did, the green tendril that had bene sucked up his ass before pushed out of his hole again. He would have groaned if he was himself, but all he felt was pleasure, and that pleasure was kept tight inside of him. The tendril pushed out slowly, rippling against his pucker, turning around until the end of that long, slimy thing was hovering just over his hoof. It expanded slowly, getting wider until -

"Waaaaah..."

The end of the creature's tail opened up, and out of it emerged another, slightly smaller creature, one that was an exact copy of the one in his ass. It unrolled itself from its curled position, skittering about on his hoof, and he slowly carried it to that stretched, exposed pucker.

Ivory was still groaning, his head buried in the earth, but that was not going to last for long. He'd need to do something to make sure that his friend didn't reject his gift, didn't start fighting it.

So, as soon as he pressed the parasite to the other stallion's pucker, he leaned down and started sucking on the other horse's balls.

"Ah...ah...oh...fuck..."

The white and black stallion thrust his hips back, probably thinking he was getting the tip of Moonlight's hoof shoved up his ass while his balls were getting sucked and licked. That was fine. As long as he didn't fight, he could imagine whatever the hell that he wanted. Moonlight twisted his head this way and that, gently tugging on those big, leathery balls with his lips, pulling them down, teasing them, licking them, tasting the slight hint of musk and sweat that clung to them after a long day in the fields.

Just above him, however, he could see the parasite wiggling back and forth against his old friend's hole, slowly using its forelegs to get a grip on either side of the pucker so that it could burrow against it. There was no cutting, no hurting, just a lot of slime coming free, coating the hole properly and making it loosen up.

It wouldn't take long for the little critter to get in. Not with a hole that had that much experience.

He grinned as he felt Ivory start to squirm backwards, trying to get up to all fours once more. The other stallion was struggling, though, lust-drunk from his own need, his eyes going wide, his body shaking as he started to hunch his hips, his cock swinging up to hit his belly.

"Ah...ah...what...what...that's not your..."

"No..."

"M-Moon..."

"Welcome to the hive."

Squelch. The parasite got its main body past the swollen rim, and just like that, it started to dig deeper. Ivory spasmed, arching his back, and Moonlight stepped back so that he could get a better look at what was going on.

His old friend stood like he was shocked to the core, his hooves pushed forward, his eyes wide and rolling back. His cock was already oozing a river of pre-cum into the earth below, dribbling and wet and thick and musky. Every little squirt added to the flow until it was a veritable flood, being milked out of him by the pressure of the hive bug on his prostate, pushing down and squeezing and -

"AGH!"

Suddenly, Ivory thrust his hips forward, and he came hard, harder than ever before, his seed hitting the earth and swelling outwards in a great white puddle. Moonlight watched as his friend's cock spasmed again, and again, remembering how it had felt when he had joined the hive, how it had felt to feel his cock jerking up and down, milked by some otherworldly force. Even now, he felt the urge to feel that again.

And he knew how, but he would have to wait.

Instead of pushing, he pulled his hooves together, laying down as he watched the other parasite take control of his friend. Once, there might have been guilt. Once, there might have been a feeling that he was doing something wrong. But no. He was part of the hive, and the greatest gift that he could give someone else was to make them part of the hive, too.

Slowly, his friend stopped shaking, and bit by bit, he was able to stand up normally again. His hooves clicked against the earth, and his head tilted slowly back and forth. This time, he understood. It was the hive parasite working out how the body worked, making contact with the various parts of the host form, turning the drone into a proper tool for the hive's purposes. It was all part of taking control.

It was fascinating and, on some level, wonderful. He felt good about bringing his friend around to the right way of things. The hive was the best thing for them, and accomplishing something for the hive was the best way to feel good in life. By bringing Ivory into the same group, he had given his old friend the best gift that he could.

Slowly, the other male turned to him, and the stallion smiled.

"This one has a bit of information for the hive."

"Then let's share it."

Share and enjoy. He knew from the parasite in him that this was a reward, a blissful thing that would bring him some hint of that first great pleasure. He got back to his hooves, turning around as the tendril sticking out his ass waved back and forth.

As Ivory approached, he watched as the other stallion's tendril push out, forcing that pucker to gape as it swayed from side to side. He slowly backed up, their asses almost touching when -

Squelch.

The two tendrils grabbed hold of one another, and both stallions went ram-rod straight, gasping and going rock-hard all at once. They could hardly breathe, at first, feeling the connection and slime as the two tendrils touched each other, the two members of the hive doing...something...

Pictures rushed through his brain, half-seen at best, and he knew that they were coming entirely from what the other stallion had in his mind, looted by the parasite inside of him. They were giving greater information to the two creatures, spreading it between them, giving the hive the communal information that they needed to operate.

And as a reward, they both were given the pleasure that they loved.

They moaned and whinnied. They wanted to stamp, hump, thrust, push, but they were held still, their bodies completely paralyzed as they were used as a helpful conduit for the information for the parasites. They could not move while the hive studied the information that they'd gathered. All they could do was whinny, pant, and moan.

The earth turned to mud under their hooves before the tendrils retracted, and both Moonlight and Ivory were eager for the break. They almost fell flat on their faces when they could finally move again, and they slid a great deal through the muck before they could find their footing again.

When they looked at each other, they no longer saw a stallion on the other side. They saw a member of the hive.

"You need to go home," Ivory said, and Moonlight knew it for truth, getting the same message from his own parasite. "And I -"

"Have to go back and fuck your wife."

"For the first time in years."

"She'll let you? Oh, right -"

"She's in heat. She can't resist."

"I have to do the same."

"She'll love it. She always does," Ivory said. "I can see it...see you...and her..."

"Not as good as you."

"But good enough. They have plans; we'll follow."

"We'll always follow."

And so they would. There was no way for them to escape the parasites on their own, and even if there was, they didn't want to. The hive had given them acceptance, a way to live in happiness and pleasure. There was no need to go back, not after they had been given something so good.

They parted with one last little caress of tendrils that left them shivering in arousal, splitting up and heading back to their farms. He looked over his shoulder once, but that was more to make sure that the other stallion was properly embedded with the hive parasite than any other reason. After all, it would not do for Ivory to have second thoughts.

As for himself, he was already imagining himself making sure that his wife was properly infested, too. She wasn't in heat, the way that Ivory's mare was, but now that he knew that his seed was corruptive, arousing, he was pretty sure that he could leave her out of it. The best way would be if he could get her to wake him up with a blowjob, leaving her sucking it out of him and getting all high and needy afterwards. She'd be too weak to resist, and he could just watch as her body was bent to the will of the hive.

If not? Well, there were plenty of other ways to seduce her into the grip of the hive, and she would accept one of them, eventually.

His cock dribbled pre-cum and cum all the way home, and he was sure that there would have been ponies asking questions if he had done that by day. As it was, he was able to make it all the way home without incident, without questions, without anyone even noticing him. Moonlight nudged the front door of the farmhouse open, walking inside with a clip and a clop.

Considering the late hour, he wasn't surprised that his mare wasn't in the front room. She was probably deep in sleep, now. If he'd had the time to make another parasite already, he would have been tempted to fill her ass with it now, to get this over and done with before she could wake up, but he needed time. They could make a few a day, but it still needed time between creating one and pushing it out to make another one.

Well, the morning would be time enough.

Finding his mare, a pink-furred pony, already lying on her side, he slid into bed behind her. His cock was slimy enough that he could have just slid right into her pussy, but he didn't bother doing that. It would be time enough tomorrow, and it would probably wake her up. If he didn't fill her up at that point, she'd probably have questions, and he wasn't sure what to say just yet. The hive didn't offer any guidance to that.

So, instead, he closed his eyes, and he allowed the hive parasite to drag him down, to put him into a state of sleep befitting a drone. His worries faded away, and he slid down into dreamland, where all he could think of were happy moments of service to the hive. That was his reward.

The End

Summary: A parasite comes to the land of Equestria and starts taking over ponies to use for drones.
