An Infestation in the Herd

Part 3

For flimflamfun5

By Draconicon

Being a drone wasn't that different to working for his backers. Sunrise had been quite the deal maker before he had come to this little village, and he'd gotten a number of deals from rather wealthy ponies. They all wanted him to take their goods hither and yon, selling the little luxury goods for them. They never made that much money, but they were vain enough that they didn't want to get money for their products, merely recognition. They got that, alright, recognized as the crap that they were.

This was not that different, in all honesty. Sure, he had less free will - well, no free will, now - but he was still doing what he wanted. It was just that, now, what he wanted was the same thing that his employers, his backers, his masters, the hive wanted. It wasn't that different...not really...

That was what he thought, at least, and he wasn't sure if there was anyone that could argue that. Certainly not the ponies that he invited in to trade, only to infect them afterward.

It turned out that some of the stupid crap that he had been trying to sell had some interesting uses when he decided to put them out for the ponies to see. The bondage harness had been perfect for allowing him to back ass-to-ass with the pony interested in it, forcing them to stay still while he fucked a parasite right into their asshole. Another one, interested in a pair of stocks as a punishment for their foal, had been rather helpless while he fed them his seed, making sure that they were well and truly out of it before they were infested with a parasite themselves.

It had been three days, and he had already infested six other ponies, each one eager to fall under the power of the hive once they had had the chance to taste his seed. He was eager to see how many more he could bring into the hive before he had to move on, and the hive rewarded his eagerness with a few tense squeezes of his prostate.

Sunrise stood behind his counter, his cock hard and throbbing under his belly. All the windows were open and several of the fans that he had for sale - little clockwork things that he had to wind every three hours - blew the smell of his musk out of the room. Much as he enjoyed it, and as helpful as it could be in other situations, it might serve as a warning for anyone that walked in and hadn't been corrupted and infested just yet. He needed to keep a low profile until a majority of the village had been pulled into the hive.

Not long for that, though. He knew that he had been responsible for six infestations, and at least two of those would have been able to infest another two. That meant a total of ten, eleven including him, and if Moonlight and Ivory had been doing their part, that meant that there were probably six more, at least, for each of them. So, a minimum of twenty-three ponies in the village already pulled into the hive.

The hive parasite squeezed at him again, rewarding him for his devotion, and he smiled as he shifted from hoof to hoof, enjoying the pleasure that was pulsing away in his ass. Every time that he did well, the hive made sure to make him feel amazing, and for that, he would keep up the good work for as long as he could. Even if it did mean that he started spraying his own goods with his seed.

He was still shifting around, getting used to the throbbing erection that hadn't gone down for the last few hours, when someone new approached the trading post. He cocked his head to the side as a horn poked around the leather sheet that covered the entrance, and blue-white unicorn followed. He had a sort of imperious look to him, his eyes narrowed, his horn glowing as he whipped his head back and forth. There was a way to him that made the merchant slightly nervous, though he did his best not to show it.

"Welcome to my trading post, unicorn," he said with a small smile. "How can I serve you?"

"You can tell me if you've had any strange customers lately."

"Strange? How so?"

"Hmmph. You'd know if you'd seen them."

Sunrise felt a prickle of nerves from the hive, and he realized that there was some genuine concern over this stranger. The stallion wasn't sure if he was okay with them feeling nervous; he'd thought that they were damn near invincible.

But he didn't let that show on his face. Instead, he kept smiling, watching the stranger with as much neutrality on his face as he could summon.

"Maybe, but I see a lot of strange things. Perhaps you can tell me what you mean?"

"Ponies that have been out of it, not focusing very well. Almost like an extreme distraction?"

"I have seen one or two like that, yes, but everyone is distracted sometimes. Anything else?"

"They would have been...showing," the unicorn said with an obvious blush.

"Showing?"

"Dropped, stallion, dropped!"

So, this unicorn was a bit of a prude, too, in addition to being more nosy than the hive would like. That was something worth noting, and something rather interesting, as well. Sunrise cocked his head to the side.

"You're saying that I should be on the lookout for ponies that are having horny daydreams?"

"No! You...Look." The unicorn sighed, shaking his head. "Obviously, we've got off on the wrong hoof. May I start over?"

"Probably the best thing that you could do."

"At this point, probably."

"Right. My name is Keensight, or Keen, for short. I'm an investigator of suspicious things."

"Are you part of the pony police, or..."

"Just a freelancer."

"Oh? Someone hired you?"

"...No, this is just personal work. Curiosity, you might call it."

The anxiety that the hive had been feeling was slowly dissipating, though it wasn't completely gone yet, not by a long shot. It was clear that this pony had come about because he had felt something changing, something that might catch the eye of someone more powerful if the hive wasn't careful, or if they didn't shut him up, now.

He could feel the parasite in him weighing the options, knew that it was trying to make a decision with limited information. Sunrise didn't push his own opinions on it. He was a drone, and that meant that he did what he was told, trusting in the hive to do the thinking for him.

Instead, he kept up his last order, making small talk, keeping Keensight from doing much more than look around.

"What kind of leads brought you here?"

"My unicorn magic helps me sense different emotions. I've been feeling high spikes of happiness around here, more than I've ever felt around a trading post before."

"Maybe it's just people finding bargains that they're particularly happy about."

"I thought about that, but I doubt it."

"Why's that?"

"Because that low-level happiness keeps spiking all over the village, and there's nothing going on to cause it. Considering the most that I was feeling from anyone around here before was contentment, it's weird to feel everyone being so happy."

"What do you think it is?"

"Either a group of changelings, or some sort of rogue unicorn, or some magical item that people keep tripping in your supply."

"You don't think I -"

"Obviously not you. You're not smart enough to pull something like that off, obviously. But you might have something here that you don't understand, something you wouldn't know the power of."

Sunrise was doing his best not to be offended by the blatant assumption that he was an idiot, but it was playing into the favor of the hive. They weren't as 'caught' as they had worried they were. This stallion had no idea just what was going on, and was spitballing to try and find something that stuck. They were in the clear.

And as soon as they dealt with him, there'd be no worries of any other unicorn finding them by the same method. No two unicorns had the same sort of magic, and that meant that they could eliminate this threat right now.

Of course, that meant getting him into a precarious position for infestation, and Sunrise doubted that this stallion was going to just bend over the way that the others had.

"Would you like to take time to peruse my wares? I can step out of the way for you to scan them for a while, take some time to examine all the different magical items."

"You have some?"

"A few."

"Then show me, and then get out. I'll be at this for a while."

Sunrise nodded, having to hide the little burst of pleasure that the hive rewarded him with. He had managed to figure out something that they wanted, at least, and that meant that he was on the right track for moving forward. The stallion stepped out from around his desk, the hive pulling his cock back into its sheath to not offend or arouse suspicion, and he trotted around the small post, pointing out the objects that had magic to them. The whole thing was harmless, all things considered; none of these items were part of the plan, after all.

Once Keensight had the items pointed out to him, the unicorn turned away, ignoring him. The way that the other stallion was completely focused on his mission was almost a credit to his dedication. Not particularly a smart thing to be doing when there might have been suspects in the area, Sunrise supposed, but a good way to keep on task.

He took a moment to ogle the unicorn's ass, looking at the taut cheeks, the way that the puffy pucker stood out. It was completely untouched, something that had obviously never been fucked, and he knew that he'd need to make sure that Keensight was completely out of it before offering him the parasite. Otherwise, he'd just get it killed.

But that hole...it was almost a pity that he would only get to fuck it once.

He turned his head away, walking out of the trading post to give the unicorn the promised space. As the leather flap stroked down his back, he looked out at the village. The hive had already taken so many of them, almost half. Soon, they'd be able to start thinking of bigger and better things, no longer having to hide what they were.

But he had to get rid of Keensight, first.

Almost as soon as he thought that, the hive offered him a suggestion, and he was rather surprised that he hadn't thought of it himself. After all, it was simple enough that even a drone could have thought of it.

My seed. If I can mix it properly...yes...

The pony trotted into town, taking his time to keep from standing out, his tail a bit low so that his pucker and the bit of juiciness that it had wasn't so visible. The other corrupted, infested ponies would understand, and the modest ones would be happy not to be staring at his ass, as if he was some sort of pony slut.

He made his way to the general store, bumping the door open with his head. The local merchant, another one of the infested, looked up. Their eyes met, and they shared a smile.

"Welcome."

"I am welcome."

"Anything that you need?"

"Water, and a cup."

"Why a cup?"

"Because there is someone that needs to drink."

Their speech was a bit less natural, but that was because they were sharing the words that the parasites needed to speak to one another. It was midday, so they couldn't risk the tentacle in this open space, and the hive was not great at oral speech. They were better with concepts, images, ways of conveying information quickly without having to go through each of the different word-pieces that made up the concept.

The infested stallion nodded, his little mustache affectation bouncing along his lips as he ducked beneath the counter. The tan pony pulled a cup out, and then passed it over with one hoof. The water was passed over in a small barrel, one that the shopkeeper slung over Sunrise's back.

"Here you are."

"Thank you. Is there anything owed?"

"Not for one of us."

"Thank you."

"Good luck."

They parted, and he half-trotted, half-hopped down the street with the glass held on his hoof. He could feel the idea percolating in the back of his brain, and he knew that this was going to be one hell of a thing.

Once he got back to the trading post, he walked around to the far side, just in case Keensight finished early. He kept the water off to the side for now, but slowly straddled the glass, wiggling his hips slightly until his cock started dropping again.

Just have to make sure that most of it goes in the cup...

Sunrise grunted as he started tensing his muscles at the base of his cock, and the hive parasite helped by doing its thing with his prostate. It took almost no time at all for him to be completely erect and hard, throbbing against his belly, and he slowly lowered himself, laying over the cup, almost touching the glass rim to his belly. Certainly, the rim touched his flare more than once as the big horse cock throbbed under him.

He had to bend his head forward a bit to watch, making sure that the throbbing thing was aimed properly. He didn't have to focus on the masturbation part, as the hive parasite was taking care of that bit for him, but he did have to focus on how it was pointed. He shifted his haunches slightly, moving his hips, keeping the thick flare pointed right at the edge of the glass.

Green-laced pre-cum dripped from the head into the glass, starting to fill the bottom and bring it up a little bit. He grinned to himself, feeling his balls rising and falling, feeling them churn with need and arousal. He could already imagine feeding this heavy load to the unicorn inside, watching as his eyes went mad with lust. He would be completely vulnerable to the parasite after that, perhaps even to a fuck.

It's been a while...

The hive didn't say no, and he hoped that they would say yes when the time came. It had been too long since he had been able to enjoy the feeling of a hot, wet ass around his cock. Usually, his backers were quick to offer their asses as well as their products, wanting to get a bit of 'common cock' before they sent him off, but this time, they'd been in too much of a hurry. He wanted to get his dick wet again, and who better than this pompous unicorn?

He groaned as his cock twitched again, pleasure squirting up and over the glass, and he had to shift his aim again as the massive rod started twitching, throbbing from the base to the tip. His medial ring was showing, now, and that meant that he was definitely getting closer to orgasm than he had thought.

A little more...

The hive helped him, controlling him so that he didn't start humping or upsetting the cup or anything like that. It pushed his hooves down, making him anchor himself, and instead of thrusting, he had his prostate squeezed, rubbed, manipulated. The parasite was making it easier for him, giving him the chance to fulfill his purpose with less chance of failure.

It was good to be part of the hive.

He felt the pleasure building up in a series of tingles and sparks through his ass, running up his spine all the way to his brain. The stallion wanted to moan, wanted to pant and whinny as he felt his orgasm coming, but the pressure on his insides kept him from doing that. All he could do was stare straight ahead, his eyes closed tight, his hole clenching hard around nothing. It was like getting fucked without getting fucked, all the prostate pleasure with none of the pleasure of his hole being forced open.

Stroke, tease, press, the parasite played, and he gritted his teeth as his cock bounced up and down, hitting the glass over and over again, pre-cum splashing out until -

He didn't even groan when his climax hit. His vocal cords felt like they had seized up, and the only sound he made was the soft hiss of air that wheezed through open lips. He huffed softly, puffing through his mouth and nose, but that was all that he managed to make in terms of noise.

In terms of cum, however, he was quite productive. He came, and came, and came, filling the cup to overflowing, and then some. The green-laced seed kept squirting free, his flare going wider and wider still, almost like a blooming flower, and he winced as he felt his balls trying to rise up yet further than they already had.

Oh, fuck, it felt good, but it was oh so intense.

He kept cumming, shooting his load all over the cup and ground, and the smell of sex was stronger than ever around him. It felt like he was swimming in his own musk. Every breath sent a shock right down to his cock, keeping him good and hard, and he swore that his hole was puckering like mad.

And then, then, it was over.

He panted hard, relying on the help of the hive to get himself upright again, his legs shaking for a moment or two before the hive helped him stabilize himself. Sunrise fumbled with the small water barrel, turning it so that he could dilute the load that he'd had. Not much, not enough to get rid of its chemical properties, but enough to make it less obviously a glass full of cum.

When it was turned into more of a cloudy soda, he put the water down and looked at the glass proper. It still had the right amount of green in the cloudiness to seem like it was going to be good enough for arousal, but he'd only know for sure when Keensight started drinking it.

He felt the 'do it' push from the hive parasite, and he moved, going back to the flap and then stepping under it.

"Keensight?" he asked.

The unicorn jumped, obviously having been hyper-focused on a clock that the merchant hadn't even pointed out. Sunrise chuckled.

"Thinking there's more magic in here than meets the eye?"

"You are inexperienced; you could have picked one up that you didn't know about."

"Well, any dangers?"

"...Not so far."

"Well, how about we take a break and have a drink, then."

"Unnecessary."

"Then just indulge me."

He offered the cup, and the unicorn arched an eyebrow. After a moment, dark blue light surrounded the cup, floating it off of his hoof and towards the other stallion. He smiled to himself, knowing that Keensight was too oblivious to the obvious to really be worried about the drink; it was more about the interruption than anything else.

He dragged the water barrel in behind him, surreptitiously pouring himself a drink. Keensight didn't seem to notice that his was clear and the other male's was not, and the unicorn continued to shake his head as he looked around the room.

"I swear, the feelings were coming from this tent."

"Why are you so sure?"

"I triangulated it, sensing for it from every part of the village. Every time that I felt it - and I could sense it from more than four miles away - the direction pointed right here."

That was something that could be useful in the future, but the hive would need to infest the unicorn to know for sure just what he could do. More than ever, he felt the hunger of the hive to have this one.

"Take a drink, Keensight. You'll think better when you're less thirsty."

"Probably, but it's a waste of time."

"Then you might as well chug it."

"...Fair point."

And just like that, the unicorn did as was suggested. Sunrise watched with a growing grin as the slimy water went down the unicorn's throat. He obviously didn't like the taste, but he chugged it down, alright. Chugged hard, too, for that matter. The cum-water bulged out his throat, and he was obviously struggling to get it all down, but the unicorn just about managed it at the end of it all.

Even before he finished the cup, though, his body was already showing signs of being tempted, teased, altered. His cock started to swell in his sheath, and his balls started churning in a most obvious way. Sunrise smirked as he sipped his own water, watching as the stud started panting, his face going red, his cock finally starting to drop.

"Ah...ah..."

"Something the matter?" Sunrise asked innocently.

"N-nothing. I...I just..."

The aphrodisiac effect of the seed in the water was obviously hitting the other stallion pretty damn hard. He was huffing and puffing more than usual, and his eyes were slowly rolling back in his head. His cock had dropped completely, and he had a pretty good-sized one, one that swelled and lifted and rolled upward until it curled around his belly.

"Nnngh..."

"You're dropping."

"You...nnngh...what is...ah...ah..."

The stallion was panting hard, his eyes rolling back in their sockets again. The first drops of pre-cum were flowing from his dick, and he seemed unable to decide between humping forward and thrusting his hips back. Sunrise stepped out from behind the counter.

"You know, I offer a different sort of service as well as goods."

"Nnngh...what are you, some sort of...some sort of traveling whore?"

"Something like that. Would you care for some relief?"

"Nnngh..." The unicorn obviously meant to decline, but the drugged seed hit him hard. He moaned, thrusting his ass back, falling down with his face on the ground and his rump high. "Fine...I...I don't know what...what's come over me...but I can't...I can't...think...need...fuck..."

"Then you'll have it."

As Sunrise approached the other stallion, he felt his cock throbbing, his need rising. Was he going to be allowed to fuck that ass? Was he going to be allowed to take his pleasure for doing well?

Yes, and no.

As he approached, his hole suddenly opened, the parasite's tendril tail pushing out. He didn't groan, because that would have implied that he wasn't obedient, but he felt a bit saddened that his pleasure was not going to be part of this.

Then, he felt the tail dropping down, wrapping around the base of his cock, and then pushing down along the underside. It had made itself part of his shaft, giving him the chance to fuck with it, and with his dick.

Fuck...fuck...rut...

He felt almost feral as he approached Keensight from behind, staring at that pulsing pucker, knowing that it was begging for him, knowing that it wanted to be filled, needed to be filled. Sunrise groaned under his breath, his cock throbbing harder than ever, but his balls staying pulled down, the tail keeping them from rising.

Of course. It had to put the new parasite in, and then he could swell that hole with his seed. It wouldn't do to make the other male even more high on those aphrodisiacs than he already was.

The stallion shivered in anticipation at the idea of getting to fuck again, and as he put his forelegs around the other stallion's hips, he could feel the hive parasite squeezing again, giving that pleasurable reminder of good behavior leading to good rewards. He moaned, thrusting his hips forward, grinding his flaring, wet cock head against that hole. Keensight moaned under him.

"W-well...are you going to...do it or not?"

"Oh, I am..."

And he slammed forward, then. The flare was so wide that he almost couldn't get his cock in, but when it slipped forward, it was perfect. He moaned loudly, feeling the tightness around his cock, something that he hadn't felt in far too long. He thrust forward again, and again, each time feeling the defiant pucker open that little bit more for his throbbing shaft, giving in and allowing itself to be molded to his whims, his pleasure.

Thrust, thrust, thrust, and he felt the edge of the tail slid in under his cock, forcing it open that much more. The stallion under him was gasping for breath, arching his back, obviously enjoying himself. More than he expected, it seemed.

"Ah...why...why the fuck...does that...ah...ah!"

He was trying to think, obviously, but there was no thinking, now. There was only fucking. The parasite inside of him was already swelling, adding more pressure to his prostate, and he could feel the beginning of the new parasite sliding down the tail. It was bulging his own asshole, making his own pucker spread wide, and that only fueled his thrusts to go further, deeper, harder.

In and out, in and out he went, his balls swinging forward, endlessly full. He moaned with abandon, savoring the rising pleasure as he plunged in over and over again, feeling that hole open and close, open and close, squeezing on him desperately.

There was some hint of pride in the back of his mind, but it was buried beneath the direction and objective of the hive. Breed and infest, breed and infest.

He was balls deep in the other stallion in short order, feeling the other male clenching on him constantly, pulling him deeper. He could see little flickers of blue light along the unicorn's horn, Keensight obviously trying to use his magic to understand, but his focus getting shattered every time. Sunrise didn't let up; if anything, he hammered his cock home all the harder.

In and out, in and out, each time feeling his balls battering the other male's, feeling them drawing up little by little, only to be tugged down by the tendril around his balls. It was impossible to get away from it, impossible to cum. He was just the delivery method for the new parasite.

And it was coming, sliding down the tail, moving out of his ass and down the tendril. He could feel it swimming, feel it running along the base of his cock, and then -

"Ah!"

And then, it was inside.

"What...I...nnngh!"

It was so intense, even though he was made to stop. The hive parasite in him didn't want to accidentally crush the new parasite in the new host's ass. There was no need to be vicious, no need to be rutting so hard, not when -

"Ah...ah...ah..."

They moaned together, Keensight probably from the parasite that was getting a good grip on his prostate, and Sunrise from the twin pleasures of having a parasite rubbing his prostate and grinding up against the base of his dick. They were rubbing him from both sides, and the tail around his balls was slowly loosening.

"Ah...ah..."

They didn't even move, but the parasites were keeping the bliss of fucking and being fucked alive. They were feeding their hosts, their drones, all the pleasure that they needed to be satisfied. In the case of Sunrise, more than enough to finish, and as soon as he felt the grip around his balls loosen -

"AHHHH!"

He whinnied and moaned and screamed as he was finally allowed to cum, squirting his load deep in that hole. He was made to back up quickly, so not everything went inside, but enough did. The rest landed on the other male's ass and back, soaking that blue fur with thick white seed, marking him as the little butt-slut that he was.

Further back he was forced, and the last of his seed splattered on the other stallion's balls. They were white as could be at the end of that, and they were swelling even as the parasite started taking control.

Sunrise knew the signs, but was nonetheless aroused as he watched them. He could see the way that the other parasite was taking control, the slow stillness followed by the experimental movements. Head turning one way, then the other, and then back again. Lifting one leg, lowering it. Testing each limb. The tail twitching to the left, to the right, and then the left again. Each part needing a tweak, a test.

The other stallion turned around and smiled.

"He was very willing," Keensight said. "And he will be called Keen from now on."

"He wanted it?"

"This drone didn't know he wanted it, but he did. And when he found the hive, he submitted."

"Will he be useful?"

"He knows more magic than just sensing emotions; he can cause them, too."

"Like our seed?"

"As good, and possibly better, if he was trained."

"Then we have someone useful."

"For attack -"

"And defense -"

"Of the hive."

They said the last one together, and the merchant and the unicorn smiled at one another. Another member of the hive gained, and one that would help them a great deal. The earth ponies were very like one another, very interchangeable when it came to what they could do. But the unicorns were different. They would be no different than the rest of the hive in how they were treated, but in terms of what they could do, they were somewhat special.

"Share what you have," Sunrise said, turning to expose the tendril still sticking out of his ass.

"Yes. The hive must be informed."

They touched, and the host dropped down. There was no more need to speak, no more need to be there. He could just feel and enjoy the pleasure that came from interfacing and interacting with the hive members. He wondered what it would be like if more than two of them ever worked together at the same time.

He wasn't sure if he could come through that with his head screwed on straight, that was for sure.

For now, though, plans were being made, and that was hive business. He remained out of it, and waited to know what to do next like a good little drone.

The End

Summary: Sunrise Spark encounters an investigator unicorn that has a unique power, but isn't particularly good at his job. Time to improve him and make him a member of the hive.
