From Within

"Have a great day! May I help who’s next?"

Derpy waved to the mare as she departed with her package, smiling politely all the while. The mare waved her goodbye, carrying her package out of the post office to make room for the next in line. It had thus far been an uneventful day at work for Derpy, at least, as far as she could tell. Delivering packages, helping customers to send out their mail, looking for prime targets to seduce and infect, all pretty standard fare for Derpy Hooves.

“Hey, Derps.”

Two mares approached the counter, the newly-engaged couple of Lyra Heartstrings and Bon-Bon. Good friends of Derpy’s ever since she moved to Ponyville, the pair were always interesting characters to Derpy. Polar opposite personalities, prone to butting heads and fighting like cats and dogs, and yet, by the time the pair came through the other side, their relationship only seemed stronger. That strength was the sort of thing that Derpy admired in Lyra and Bon.

The Hive was more interested in the open nature of the swingers’ relationship, however.

“Hey, guys!” Derpy waved to her friends, smiling brightly as the mares approached. “What can I do for you? Or are you just here to visit?”

“A bit of both, actually,” said Bon-Bon. “Can we talk a bit? If you’re busy, we can come back later.”

“But there doesn’t seem to be anypony else here, so…” Lyra grinned. “We should talk now.” Bon-Bon elbowed her fiance in the side, at which point Lyra amended her statement. “If you’re free, I guess.”

“I was just about to have a coffee break, actually. C’mon!”

Derpy beckoned to the two mares, who rounded the front desk and followed Derpy to the back of the post office. Down a short hallway was a small break room, containing little more than a sink, coffee pot, vending machine, a round table with four chairs, a small refrigerator, and a microwave. Derpy poured out a coffee for each of them, adding sugar and cream where applicable (Lyra liked it straight black, while Bon-Bon predictably had a bit of a sweet-tooth). The mares accepted with a thanks, sitting down at the round table so they could have their chat.

“So, what’s up?” asked Derpy. Lyra and Bon shared a look, silently discussing who would take lead in the conversation.

“Well… I don’t know if it was supposed to be a secret, but…” Bon-Bon smiled a bit sheepishly. “The Doctor had us over for tea yesterday and… he told us everything.”

“Huh? What do you—”

“Doc told us how he dicked your brains out onto the pavement,” laughed Lyra. Bon frowned at her fiance, her disapproval met in equal measure by Lyra’s amused, self-satisfied smirk. “What? If we did it your way, we’d be here all day!”

“Oh… I didn’t expect him to tell anypony yet…” said Derpy, shrinking down and giving her best embarrassed grin. “I was trying to find out the best way to tell you guys, but I guess Doc beat me to it, huh?”

“First of all, we’re both super happy for the both of you,” said Bon.

“It’s about time you two goobers got together.” Lyra winced as Bon-Bon elbowed her again, and she snorted in frustration. “Like you weren’t thinking it…”

“I knew I should’ve come alone…” Bon-Bon shook her head before turning her attention back to Derpy. “What we’re really here for is to see if you might be interested in something a little… Unusual.”

“Unusual? What do you mean?” asked Derpy, tilting her head innocently. She sipped her coffee, watching carefully as her friends did the same. “You don’t mean, like…”

“It’s pretty much common knowledge that Ly and I have an open relationship,” explained Bon, taking another healthy sip of coffee. Something about this particular cup was extra tasty, perhaps even addictive. “But it’s actually a little more complicated than that. We have an agreement on who we can sleep with, and neither of us can hook up without getting the okay from the other. We’re very careful about who we invite into our bedroom.”

“Yeah, only ponies we really trust and like. Like… You and your new coltfriend,” said Lyra with a smirk. “So, we were wondering if maybe you two would like to fool around with us tonight?”

“Oh, wow…” Derpy blushed, rather convincingly, in fact. “I’d have to talk to Doc first…”

“We already did. He’s interested, we just needed to run it by you.” Lyra grinned, bouncing giddily in her seat. “So… Are you interested?”

“I’ve never done anything like this before, but…” Derpy matched Lyra’s grin and nodded eagerly. “I’m in! When do we do this?”

“Awesome! See, Bonnie? Told you she’d be down to clown!” said Lyra, nudging her fiance. “We’ve gotta get stuff ready, but how about we come pick you and Doc up at his place say… 7 PM?”

“Sounds good to me! Can’t wait!”

“Oh man, I’m getting antsy just thinking about it!” Lyra finished off her coffee, not suspecting that it was in any way related, and rubbed her hooves together eagerly. “This is gonna be so much fun!”

“Easy, Ly. We should take it easy,” said Bon. “We’ll scare them off if you’re too… ‘Lyra’ about it.”

“I don’t remember hearing you complain about my being too ‘Lyra’ when you were sitting on my face last night.”

“Lyra!”

“Oh, so we can invite her to have sex but we can’t talk about it in front of her?”

“Heh. Well, as excited as I am, I should probably get back to work,” said Derpy. “Do you guys want more coffee before I go?”

The two mares nodded, which was what Derpy had been expecting, and they graciously accepted the drinks when Derpy delivered them. They were finished with their beverage before Derpy had even led them back to the front of the store, and they had a noticeable fidget and quiver as Derpy waved them away. Not once did they suspect that the coffee was more than it appeared, spiked with the same aphrodisiac precum that had set the stage for Derpy’s own infection.

Now, with two more prepped, the invasion could continue on as planned.

“Thank Celestia you’re here!” exclaimed Bon-Bon. “Ly is dying to get started.”

Derpy smiled, leaning her head against “The Doctor” as they were greeted by their friend. Bon-Bon waved them in, leading them through the foyer and to the living room, where Lyra was waiting. Bon let out a surprised yelp, blushing profusely and averting her eyes from the sight of her fiance sat on the couch, legs spread and rubbing her cunt eagerly.

“Lyra!” Bon-Bon was glowing red with embarrassment. “We have company!”

“Company that’s here to have sex. You sure are weird about this whole swinging thing." Despite how she teased her fiance, Lyra did close her legs and made herself a smidge more presentable for their guests. "Sorry. I've been antsy since earlier. Couldn’t wait for you two to show up.”

“We’ve been excited, ourselves,” said “The Doctor” with a smirk. “Shall we get started?”

“Mh-hm. If everypony’s ready to go…” Bon-Bon gestured to the couch, directing her friends to sit. “Me and Ly have this kind of tradition where the stallion gets our attention first, since we’re normally mare-on-mare.”

“Yeah, dick is like a special occasion thing for us,” added Lyra.

“So if you don’t mind waiting just a sec, Derpy?”

“Oh yeah, no problem here!” Derpy twitched and fidgeted, rubbing her thighs together restlessly. “I kinda wanted to watch anyway.”

From there, the happy couple of Lyra and Bon slid to the floor in front of The Doctor, watching eagerly as he opened his legs to reveal his stallionhood. The engaged mares shared a look, a mix of concern, anxiety, desire, and excitement, before leaning forward to give the intimidatingly big tool a slow, sensual lick. Almost immediately, clear, sticky precum began to sputter from the tip of The Doctor’s cock, which the mares eagerly lapped up. Their eyes rolled back, neither mare quite prepared for just how good it would taste. It was indescribable, almost more of a sensation than a flavor, setting their bodies alight. Their eyes went heavy with lust, and a fiery desire burned between their legs, driving Lyra to reach over and tease Bon’s pussy with a hoof. Soon enough, Bon-Bon was doing much the same to Lyra, their pleasure almost secondary to the main task of licking up more and more of The Doctor’s pre. Most important to note of the sticky, clear goo wasn’t it’s flavor, but it’s almost addictive properties.

Lyra went up, while Bon-Bon slid her tongue down; The latter mare inhaling The Doctor’s musk and wrapping her lips around his balls, and the former opening her mouth wide to take his head into her mouth. They worked together seamlessly, sucking and licking at The Doctor with the goal of producing more of that delightful precum. Once Lyra had swallowed quite a bit of it, she and Bon-Bon switched, to give the other mare a taste of what they had come to desire. They moaned in delight, savoring every bit of The Doctor’s flesh, grinding themselves against their partner’s hoof and bringing themselves nearer and nearer the edge.

Unnoticed by the mares, Derpy stood up from the couch, stepping around until she was behind Lyra and Bon. She inspected both mares carefully, measuring her target before deciding on Bon-Bon. Derpy grabbed her by the flanks and, with a strength beguiled by her gentle, bumbling nature, easily hoisted her up, barely noticed by the mare in question, who was so focused on The Doctor. Derpy said nothing, simply rising up to mount Bon-Bon, gently lowering herself onto the candymaker’s back. If Bon found this strange, she certainly made no mention of it, too busied with the cock before her. Derpy didn’t mind. If anything, it made her job much simpler.

There was a slight wet, squelching sound, and slowly, a thick, tubelike appendage grew out, pushing past the lips of Derpy’s cunt and sitting not unlike a stallion’s own cock. This organ was quite a bit simpler than that of a true penis, however, and it had a few key physical differences. Derpy’s appendage was segmented by large portions of rigidly scaled flesh, coming to a pointed tip with a rather large opening, larger than that of a stallion’s. It was also perpetually slick, some manner of gland responsible for self-lubricating the ovipositor.

Derpy pushed Bon-Bon’s tail aside and, with no pomp or circumstance, forced her tip into the tight ring of Bon’s flank. A moan escaped Bon-Bon, who was too dazed by The Doctor’s addictive precum to think about anything other than how good Derpy’s appendage felt, spreading her apart. She shook and trembled a bit, her head going down low to the floor while Derpy mounted and bred her. After a bit, Lyra was made privy to her fiance’s moans, and she turned her attention away from The Doctor for the first time since she began essentially worshipping him in the first place. Her eyes went wide, a bit confused to see her meek, mare friend Derpy drilling Bon-Bon with what looked like, from Lyra’s perspective, a rather impressive member. Before she could voice her confusion (and admiration for the fucking Bon-Bon was taking), The Doctor took advantage of her preoccupation; He spun her around to face away from him and pulled her by the tail, yanking Lyra into his lap. He very easily lifted up and lowered her flank down onto his cock, immediately matching Derpy’s speed and pounding Lyra’s ass.

Any pain the mares may have been experiencing was drowned out by the electric, infectious, unshakable pleasure they felt. They weren’t concerned with the strangeness of the situation, because they simply couldn’t think about anything except getting fucked, taking what their partners were dishing out. Lyra bounced eagerly on The Doctor’s pole, rubbing her clit while she did. It wasn’t long before Lyra was quivering, letting out a deluge from her pussy as she reached her peak. Her shriek of pleasure was soon matched by Bon-Bon, who also came from the force of Derpy drilling her ass into the floor.

As their respective mares reached their climax, The Doctor and Derpy arrived at their own finale; A jet of sticky green liquid brought with it an egg that wriggled into their new homes, completely unnoticed by the mares currently in their afterglow. While they recovered, the eggs swam and teleported to their brains, latching on and sending out a surge of magic.

The energy made the mares tremble and quake, twitching and quivering until they collapsed to the ground while the parasite rewired their thoughts. Their likes, dislikes, even their love for one another, all became secondary to their one true love, the only thing they cared about now: the parasite in their brain, and the glorious changeling Hive. It was a relatively slow process, taking a bit more than a minute to push their desires aside, each electric spark of transformative magic making both new hosts twitch. Those sparks weren’t just felt in the mind, but in the host’s entire body. Bon-Bon quivered and convulsed, the sensation of her mind being rewritten sending her into another orgasm.

Their eyes rolled back in their head and, just as quickly as it started, it was over. Lyra and Bon-Bon pulled themselves up from the floor, standing upright and looking The Doctor in the eye with a glazed, vacant expression and a wide, unnerving smile. This version of the parasite was even stronger than the one that had infected Derpy, more aggressive. Perfect for The Hive’s purposes.

"I am ready to receive my orders," said Lyra and Bon, at the same time and with the same even monotone to their voice. The Doctor stood up, relaying the orders to the new sleeper agents, as well as new directives for Derpy. With their numbers growing, the invasion force could make some larger strides in their plan. Things were progressing as expected, and it was only a matter of time before Equestria fell, as all kingdoms did sooner or later.

All for the glory of The Hive.

Lyra and Bon-Bon had been very, very busy as of late.

Formerly, they didn’t invite other couples to the bedroom terribly often, perhaps every few months. They both preferred when swinging felt more like a special occasion than the status quo. That all changed after their night with Derpy and The Doctor. Now, Lyra and Bon found themselves with a new couple every weekend, and sometimes even independently of one another during the week. Lyra didn’t think to mention her weekday escapades to her fiance, nor did Bon think it necessary to mention hers. Somehow, they both knew the other wouldn’t mind.

Coincidentally, around this time, Bon-Bon introduced a new candy to her shop, a dark chocolate and amaretto truffle that was doing very well in Ponyville. Some chalked it up to some secret ingredient, something to give the candy such a delectable, addictive flavor, but Bon-Bon never confirmed that. She was likely to point to the amaretto in the candy; the liqueur did have some alleged aphrodisiac properties, after all. The secret ingredient… Well, from what Bon-Bon could tell, people were plenty happy with the candies, and that’s what really mattered.

Bon-Bon sighed, wiping down her counter as the day ticked to an end. She had been so busy with work, and candy-making, that she barely had a moment to herself all week. She sipped her coffee, the same addictive, aphrodisiac recipe that Derpy had shared with her the last month. The coffee certainly helped, but at the moment, Bon-Bon felt like she needed more than just a hot drink.

“Hello? Are you still open?” A stallion slipped into the shop, a thin, lithe, almost fragile looking pegasus with a pleasantly pale pink coat. He looked soft, gentle, easily malleable. In other words, perfect for Bon-Bon. “I hope I’m not too late.”

“Not at all! Come on, don’t be shy.” Bon finished off her coffee and set it aside, smiling politely as the stallion made his way to the counter. “What can I do for you?”

“Well, tonight’s my anniversary, and my boyfriend loves chocolate,” said the stallion. “I was hoping to get him a little gift.”

“Ah, yes. If romance is your game, may I just suggest our new amaretto truffle?” Bon-Bon ducked under the display case and withdrew a tray of the aforementioned sweets, setting them down atop the counter. “Dark chocolate shell with an amaretto syrup. Absolutely delicious, and some say it adds a little extra spark of passion. Just between you and me, when my fiance tested these, she was insatiable. Had to pry her off me with a crowbar.”

“Is that so? Things have been a little rough between us…” The stallion tilted his head curiously. “Is there any way I could maybe sample it?”

“Absolutely! Help yourself.” Bon nudged the tray forward, watching the stallion grab up one of the perfect little chocolates and pop it into his mouth. He let out a surprised little hum, which shifted into a satisfied moan as the “amaretto” squirted from the shell and coated his palette. “So? What do you think?”

“Wow, that’s amazing! I’ve gotta stop myself from eating the whole tray!” The stallion smiled, reaching into his saddlebags to pay for the chocolates. “How much for a dozen?”

“Actually… You’re a big strong stallion. I’ve got this crate I need carried home and I just can’t seem to lift it,” said Bon-Bon, gesturing to the wooden box over in the corner. “I only live just down the road. If you would be so kind as to carry the box for me, your chocolates are on the house.”

“Sounds like a deal.”

Bon smiled, watching the stallion fidget ever so slightly. His cock had grown stiff between his legs, unbeknownst to the man himself, which was precisely what Bon-Bon had been anticipating. The candymaker directed traffic, instructing him to lift the crate she had pointed out earlier. The stallion did so with ease (the box felt as though it held nothing at all, but he didn’t question it), and he obediently followed Bon-Bon out of the shop.

True to her word, the walk was a brief one, just up the walking path to the humble little house that Bon-Bon and her beloved called home. She pushed open the front door and directed the stallion to the kitchen while she herself sat upon the couch. The stallion set the crate onto the counter and rounded back to meet Bon, a bit shellshocked by what he saw. The homeowner was sat on her couch, lounging with her legs spread as her hoof explored her pussy.

“What… Are you doing?” he asked, his brow arched in confusion. Bon-Bon let out a tiny moan as her hoof brushed against her clit, and she didn’t slow down in the slightest to answer.

“Masturbating. It’s been a long day,” said Bon plainly. “Wanna come eat me out?”

“Uh… I’m gay?” said the stallion, as if that were the biggest problem with the situation. Somehow, the idea of going down on a woman wasn’t as off-putting as he might have previously anticipated. In fact, it sounded rather enticing. “Like, really gay, actually.”

“Me too. Let’s pretend for a bit, okay?” Bon-Bon gestured to her guest and spread her legs a bit wider. “C’mon, my fiance won’t be back for like an hour. Just lick me a little, okay?”

“Well… Okay. Just don’t tell anypony.” The stallion felt his body drag itself forward, dropping him down onto the ground before the candymaker. He couldn’t explain why, but the cloyingly sweet aroma of Bon-Bon’s pussy pulled him in, drawing him forth to get a taste. With a clumsy, unpracticed mouth, he tongued at Bon-Bon’s cunt, the addictingly saccharine taste of her nectar clouding his already somewhat fuzzy thoughts. With each lick of Bon-Bon’s wet, hot cunt, the stallion could feel himself growing harder and harder, his dick drooling a steady drip of pre onto the carpet. He was so focused on licking Bon’s pussy that he didn’t notice the sound of two more ponies arriving from the back of the house. He glanced up to see Lyra leading the way, followed closely by a larger, sturdier stallion than himself. He thought he looked familiar, but he couldn’t quite place it at the moment, his attention devoted almost entirely to eating Bon-Bon’s delicious pussy, trying to get every drop of Bon’s sweet, delicious juices onto his tongue as possible..

“How was work, hon?” asked Lyra, leading her stallion to the couch. Instead of receiving some oral gratification of her own, she gestured forward to her soon-to-be wife and the stallion pleasuring her; the bigger stallion nodded and strolled around until he was behind the thinner, softer stallion from Bon-Bon’s candyshop.

“It was okay. Really needed this, though,” sighed Bon-Bon. She bit her lip and, with no warning, wrapped her legs around her stallion’s head tightly. She let out a satisfied wail as she came, spraying his features with sticky, sweet, addictive marecum, chuckling slightly as the stallion gagged and coughed on her juices. Just as forceful as his sputtering was his attempts to slurp up her sticky nectar, even as he slightly choked on it. “Fuck, yeah… How about you?”

“Had the day off. Been fucking this stud all day,” laughed Lyra. She leaned over and rested her head on her fiance’s shoulder. “I think these two know each other…”

“Boyfriend.” The bigger stallion grunted that single word before grabbing the smaller stallion by the tail, and it all suddenly came back to him; This big hunk of a man that was pulling his flank up was his boyfriend, and he seemed to have less than pure intentions; The Boyfriend was hard, with a cock that put the Small Stallion to shame, and he seemed intent on using it.

The Boyfriend prodded the Small Stallion’s tight hole with his impressive equipment and—whether due to the transformative properties of Bon-Bon’s marecum, The Boyfriend’s cock being slick with Lyra’s juices, or a combination of the two—The Boyfriend very easily forced his way into him. He jerked his hips into the Small Stallion, slamming him into Bon’s muff with each deep stroke. The Small Stallion moaned into Bon-Bon’s lower lips as his boyfriend drilled him deeply, rocking their bodies with his powerful hips. The Boyfriend didn’t say anything as he pistoned his hips, and the Small Stallion had little to offer in terms of words at the time. His Boyfriend was being so rough, so deep, in a way the Small Stallion didn’t think was possible from his usually gentle, tender lover. Though unprepared for such treatment, it was impossible to deny its efficacy, especially when the Small Stallion let out a groan, his cock twitching and dribbling his load down onto the carpet.

The Boyfriend grunted in kind, letting a deluge of sticky green cum spray from his cock and into the Small Stallion’s tight ass. Closely chasing that green goo was the wriggling, bulbous shape of an egg, which quickly squirmed into the Small Stallion’s pucker. The egg made its way through the Small Stallion’s body, squeezing its way past his prostate and causing another trembling orgasm to drool from the Small Stallion’s half-hard cock. As the Small Stallion stopped to catch his breath, his body lurched, and a surge of green energy sent a tremor through him.One last time, he moaned, collapsing and spraying the biggest, thickest load of the night onto the floor. He went still, standing up straight and blinking his glowing emerald eyes, the green light fading back to his formerly blue irises. A thousand voices whispered in his brain, melding from individual sounds into the single, constant stream of knowledge, consciousness, and understanding that stood as the changeling Hivemind.

“I am ready to receive my orders,” said the Small Stallion. Lyra and Bon smiled, each of them reaching over to tease the other’s cunts. Lyra kissed her fiance on the neck, leaving Bon-Bon to give the instructions.

“Go out to a club and celebrate your anniversary. Three stallions each,” said Bon-Bon.

The Small Stallion and his Boyfriend nodded, pecking each other on the cheek before cleaning each other up a bit; The Boyfriend lapped Bon-Bon’s sticky fluids from the Small Stallion’s muzzle and, when he was finished, the Small Stallion stooped down to suck and lick any evidence from his Boyfriend’s fat cock. Once the two clean and ready for a night on the town, they gave another nod and strolled out of the home as if nothing strange had occurred at all. The engaged couple watched them leave before diving in to kiss once again. When they broke apart, their hooves returned to their sides, and they wore matching sultry smirks.

“That’s three for you this week,” said Lyra. “I’m at five.”

“Shoot. I need to catch up,” chuckled Bon, feeling her hungry pussy quiver in anticipation at the thought of bringing even more ponies into the Hive’s control. “Wanna hit the club? See if I can’t match those numbers?”

“Of course. For the glory of The Hive.”
