A trio of humans in a post-apocalyptic world taken over by very horny parasites - some of which spread by sneezing, and others by crawling inside you - try to deal with one of their friends getting infested. How do you figure that'll go? If you like parasites, or becoming a dumb horny slut, this story's for you - but do read the tags, I imagine it's a bit rich for some of you! It's also a rare story featuring only humans, but don't worry, we'll be back to furries for the next one! Anonymously commissioned.


Kevin barged in, nearly slamming the door of its hinges. He was supporting Jake, who was in turn mumbling, leaning on his friend, with a dazed look on his face.

“They got Jake," Kevin shouted, gently but slowly shoving Jake into one of the many abandoned patient rooms. He slammed the door shut, and then nearly dropped the keys as the fumbled to lock it. Bruce, not questioning him, helped pull a bookshelf to block the door.

“What happened?" Jessica asked. She'd known it'd happen to be one of them sooner or later, but it still felt unreal.

“One of the bimbos. He got too close, and she probably sneezed on him. I heard him scream and by the time I got to him…" Kevin sighed.

“How bad is it?" Bruce asked, panting with exertion.

“Bad. He's gonna turn. He had some of the slugs on him already when I found him, but at least I managed to drive the bimbo off," Kevin replied, his voice seething with anger.

To someone who just woke up from a coma, their discussion would've seemed ridiculous. Here they were, the four of them the only humans in one of the city's largest hospitals, which they'd successfully barricaded when the parasites came.

The parasites, well, nobody had really figured out their origin. Aliens had been the dominant theory at first, and then it'd shifted to genetic engineering. Now, the origin didn't really matter. There weren't enough people left to do anything about it, at least not in this city.

It was, in effect, the zombie apocalypse every movie of the 2000s had imagined, except far less gory and more like someone's wet fantasies. Two seemingly symbiotic parasites had appeared in New York, and from there, they'd quickly spread. One was a microscopic fungus, or so scientists had thought before global communications broke down. It quickly drained the victim's intelligence while lowering their inhibitions, and the worst thing was that it was not only airborne but spread by sneezing.

The other, taking advantage of the dumbed-down hosts, was a strange breed of slug. These slugs could not only colonize the human body after entering it, usually first through the ear and then through the genitals or mouth, but they could transform it. A victim who had only been infested with one of the two could still be saved. The “fungus", alone, would quickly die off and its effects weren't permanent, if proper antifungal medication was administered. Less so if the victims got “slugged". The slugs seemed to not only make their victims feel amazing, which made them resist treatment, but permanently changed their physiology to make them into more compelling spreaders. The head of the colony – the slug that entered through the ear – bonded with the brain, effectively taking control of what little faculties remained and redirecting all natural urges towards their own, sinister goals.

For women, this usually meant larger breasts. For men, it meant a larger cock and balls. For both, it meant a sky-high, uncontrollable libido, and with that, an overwhelming desire to fuck, thus spreading it. The victim would typically sneeze on another, and then proceed to seduce them as they slowly became more and more receptive to it, until they were excited to have a slug, usually one freshly birthed by the earlier host, inserted into them.

Needless to say, as with anything sexual, humanity had been powerless to resist. Men in particular took the opportunity to enjoy the newly and suddenly horny women, getting infested in the process. Women weren't much better in the end, and although their minds seemed to resist the infestation a little longer, eager men with impressively large cocks were too much for most to resist. There'd been precious little rape, even. Most had gone willingly, not believing that the infestation was as bad as reported – the victims seemed to be enjoying it, after all – and the ones that hadn't had succumbed soon after the airborne half of the infestation had caught them.

There'd even been cults that sprang up, intentionally spreading it. Most infested were too dumb to plan like that, but not all. Some retained a vaguely human, if primitive, level of intelligence. The promise of constant hot sex had been an easy one to sell, and so, here they were.

All of that had happened over the course of six months. Now, every city that the three survivors had heard from was a non-stop orgy, though mostly between the already infested as they worked on breeding more slugs, wallowing in the constant sex while sneezing out what little intelligence remained.

Jessica, along with Bruce, Kevin, and Jake, had managed to hide after it really started to go down. At first in a closed off mall, and then in the hospital after Bruce cut himself badly and needed first aid. He'd survived, luckily enough. The infested didn't even bother trying to break in, and why would they? Sooner or later the four of them would either get infested by accident, or they'd have to leave in search of more food. It was all but inevitable, at that point.

And here they were, now, with poor Jake locked away after the inevitable had indeed happened. The remaining three crowded around the windowed door to watch him squirm and moan, languishing on the bed inside.

“Is there really nothing we can do?" Jessica whimpered.

“Nope. We go in there now and we'll get infested too. He's definitely been slugged, just look at his cock," Bruce replied, gruffly. Indeed, Jake had already torn his parts off, and he seemed to be panicking at the sight of his swollen cock. It was panic mixed with lust, though, and he shook his head repeatedly as if trying to clear his mind and understand what was happening. From the way his hips bucked on instinct every few minutes, it was obvious he was starting to feel horny, and it'd only get worse from there. Around his face, there was a pinkness – of course the fungus was pink – and each time he sneezed, some of the panic seemed to fade away, a dopey grin slowly spreading on his face.

“Fucking gross," Bruce groaned, turning away from the window.

Jessica stared. Jake fought the urge to touch his cock a little longer, casting pleading glances towards her through the window, but eventually let out a dissolute moan as his hand slowly crept to clasp around that obscenely long shaft. He must've been like twelve inches or longer. Thicker, too. The slugs caused that so they could more easily crawl out of the host's repurposed balls. With no partners around, they usually resorted to simply masturbating, leaving the slugs everywhere so that they could happen to infest someone else, like little living traps.

She had never really watched the process before. Bruce and Kevin had. It was mystifying to say the least, seeing Jake gradually get more and more openly horny as he began to masturbate, occasionally sneezing a puff of pink into the air without as much as trying to cover himself. Had she not known what was actually happening, she might've been tempted by such wanton desire. The sight of him stroking that honestly beautiful member was mesmerizing, and quite erotic. But it was meant to be, so more would get infested and have their brains drained by the parasites. It was all a trap, designed to appeal to the lowest urges of humans like herself.

Then, she saw something that made her gasp. At first, she wasn't sure if she really saw what she saw, but then, it pushed further out of his cock. A colorful slug, sticking its slimy head trough the slitted glans crowning that massive shaft, accompanied by a loud and pleasured moan from Jake. Supposedly, birthing the slugs felt better than… well, anything else, as Jessica remembered it.

Finally, she turned around too. The sight had left her feeling warm and damp, and that in turn left her feeling ashamed. It was disgusting but seeing a good friend of hers being so needy still had an effect. She forced herself to think of something else as she made her way to the cafeteria, where Bruce and Kevin were already talking.

“We can't keep him locked up in there forever, that'd be too cruel," Kevin sighed, throwing his hands up.

“So, what do we do? Let him out so he can infest us too?" Bruce replied with a snarl.

“Let him out and then leave. We'll find another place to stay," Kevin replied. “The infested sleep at night too. We could easily make it out of the city."

“And where do we go? To some farm, hoping we don't get shot or infested just so we'll have fewer supplies to work with? Just because Jake couldn't keep his cock in his pants?" Bruce countered.

“Come on, you know he didn't do it intentionally!" Kevin huffed. “He'd never do that."

Bruce snorted. “Yeah? I knew him better than you. You bet he saw a horny bimbo and thought he could fuck her without catching the bugs if he was quick enough. The idiot."

Bruce did care about Jake. Or at least he had. They'd been in the same fraternity at the university. To Jessica, it seemed like he got abusive out of frustration. That said, the remaining three of them had all been tempted to take the chance to an extent, at some point when scavenging. Jessica could remember a male infested who'd been masturbating at a street corner, winking to her as she passed by. They didn't always bother approaching others, unlike traditional zombies. Some simply waited to be approached. And she almost had. Having spent this long without any kind of carnal relief had left her just as pent up as the men. One might think that they had an easy solution to the problem between the three of them, but Jessica had rebuked their advances, not wanting to risk getting pregnant, even with a condom.

That, and the nature of the infestation had made her overly anxious about even natural, healthy sex. You couldn't really know someone was infested at first, and by the time you did know, it was too late.

Luckily, the day-to-day scavenging and survival left them with precious little time to get horny anyway. Jessica could believe that Jake had been too tempted by the possibility, but she chose not to. He wasn't that dumb. Or well, he hadn't been before the infestation took hold.

“We can't just let him starve, Bruce," Kevin sighed. “He's still… well, at least he's a person, even if a different one."

“Fuck it. Fine. We'll leave the door unlocked so he can eventually push past the barricade. And by then we'll be long gone. Where, though?" Bruce shot back.

“We'll just travel at night, right? And shelter wherever we find it. I know there are some malls outside of the city we could loot," Kevin suggested.

And so, they kept arguing. Jessica leaned more towards Kevin's point of view. Travel at night wasn't nearly as risky as Bruce made it out to be. Really, if it wasn't for the sneezing, they could've probably travelled during the day too. The infested didn't usually force themselves on anyone, they didn't need to. Still, it wasn't unheard of, and so the night was safer.

Eventually, Bruce relented. They'd leave tonight and try their luck elsewhere, leaving Jake behind. Jessica still insisted that they give him one last meal, though, which both of the men protested at first. It was too dangerous to open the door, they said, but then again – the door did have a window, so they'd know exactly what Jake was doing. They'd pack their stuff, leave one last meal in Jake's room, and then they'd be gone once the night fell. It was a plan as good as any; none of them even wanted to entertain the thought of killing their former friend. The infested, for as animal-like as they acted sometimes, never lost all of their mental capacity.

At dinnertime, they went to Jake's new room – or perhaps one could call it a jail cell, now – together, to make sure he didn't attack any one of them. Sure enough, they found him pretty busy, doubled over and sucking his newly enlarged cock eagerly, which immediately grossed Bruce and Kevin out. A few slugs had climbed along the walls of the room, and that did the same to Jessica. They'd left little slimy trails, but she knew from experience they'd be a lot stealthier later on. More agile too. The little fuckers could move fast when they sensed a host, and even faster when they sensed an opportunity to crawl into one. Still, unless the victim was immobilized – or drunk and horny on the spores – they weren't too much of a danger.

She'd had one land on her face in the early days of the apocalypse, immediately setting off for her ear, but she'd managed to catch it and throw it away just in time. Sometimes she wondered what it'd feel like, if it did happen. Would she notice that she was losing herself? Would it feel good or terrifying? One thing nobody really knew was if the original mind of the host remained after the slugs bonded with the brain and took control, or if it simply changed their personality.

She realized she was staring at Jake thrusting into his mouth, listening to the obscene, muffled slurping and moans. He wasn't just enjoying it, he was enraptured by sucking his own cock, as if the rest of the world didn't exist at all, only caring about getting another mouthful of cum. It'd be a big mouthful too. The infested came a lot. Sexual preferences also stopped existing the moment someone became a host, it seemed. Jake had been strictly heterosexual before all this, but right now, he was sucking himself like his life depended on it, and none of the three doubted he'd suck Bruce and Kevin just as enthusiastically.

“Makes me wish I could do that, honestly," Kevin blurted out, trying to break the uncomfortable silence.

“What? Now that is fucking gross, at least Jake there has an excuse," Bruce grunted. “Sucking your own cock? Pretty gay."

“It's just masturbating with your mouth, idiot," Kevin replied. “Not like you have to swallow either."

“Guys, cut it out. Not important. So do we have everything ready to go?" Jessica interrupted.

“Yep. So, we leave him one last meal, move this shelf so he can push his way out of there and join the other slug-brains eventually, and we're out before he can actually do it," Kevin said, looking through the window briefly. “Not that he's gonna be in a rush to get out, I think."

“Could say that. He might actually blow himself to death in there," Bruce said. “At least it'll be a decent way to go, I guess. For someone who likes sucking cock. Just imagine the obituaries-“

He paused, a grimace on his face, as the reality of there no longer being any obituaries, or newspapers to them in, sank in. He and Kevin wordlessly moved the shelf enough for the door to slam into it. Jessica unlocked the door. With some effort, Jake would be able to force his way out, they figured, if he wanted to. Throughout the whole ordeal, their former friend didn't pay any attention, clearly preoccupied by what he was doing.

Just as they were about to leave, though, he suddenly let out a loud groan, and Jessica, who was the only one actually looking through the window, saw his cock flex and buck, his hips trembling and thrusting weakly. He was cumming, and not only that. He was thirstily swallowing every drop of it without even a little hesitation. The way he gulped was loud too, like he was forcing down entire mouthfuls of his spent seed, a blissful look on his half-lidded eyes as he worked on milking himself dry.

The sight left Jessica's panties feeling a little damp, which immediately manifested itself as a sensation of guilt. Here she was, staring at the infested and getting horny, which was exactly what they wanted her to. She turned around and noticed that Bruce and Kevin were both staring at her.

Thankfully, her arousal was easier to hide than theirs would be. Not that they didn't suspect it. Jessica was thankful that they had the sense to not offer themselves for her enjoyment. In the early days, all three of them had constantly been trying to get into her pants. At most, she'd given them blowjobs just to make them a little more resistant to the infested, but that had left her terribly needy in turn. One of these days, she knew, she'd have to let them fuck her, even if it meant risking pregnancy. As long as she kept careful track of her cycle, it should be doable.

For now, though, they had other worries. The sun was already setting, and that meant it was time for them to get moving. Just a few things remained to be packed, like today's leftovers. One couldn't waste anything nowadays. A quick trip of the cafeteria later, that was sorted.

Then, they opened the doors, and Jake was standing there, his cock achingly erect, slugs crawling along it, and a dazed, vapid grin on his face. He looked like was about to say something, as if he didn't even know he was infested, and then suddenly looked distracted as he inhaled sharply.

Jessica realized what was about to happen and pulled her jacket up to shield her face. Kevin saw her do it and followed suit immediately. That left Bruce uncovered when Jake's head suddenly snapped forward as he sneezed, spraying all the three of them in pink goo and a lot more of it swirling around like mist in the air around them. Jessica and Kevin backed away until they were a safe distance away, but Bruce didn't. He stood there with a terrified look on his face, frozen. In the shock of the moment, he'd inhaled a good lungful of it.

“Fuck," he groaned, steeling his mind to resist the inevitable as the pink mist blanketed his face and tingled deep in his nose, where it'd quickly reach his brain. What surprised Bruce was how oddly pleasant it felt, despite the horrific reality of what'd just happened. It felt soothing, in a way. If it wasn't for the facts, the tickling in his sinuses would've been enjoyable.

Then, Jake was on him, and his massive erection pressed eagerly against Bruce's thigh. Immediately, Bruce shoved him back.

“Get the fuck away from me, I'm not interested," Bruce growled, clenching his fist.

“Aww, c'mon, just enjoy it," Jake drawled. He even sounded stupid. “You'll love being all sexy and horny," he added, in a sing-song voice.

“The fuck I will," Bruce countered. The sensation in his nose was spreading deeper, though. It was like a warm, fuzzy glow now, but it was growing itchier too. Like he really wanted to sneeze. He covered his mouth and nose. “I'm not gonna give up like you with your fucking bimbos."

“Come ooon," Jake cooed. “You'll love sucking your own cock after we get a few of these feel-good slugs inside you. Or mine," he grinned, waggling his cock at Bruce. “You can't fight it anyway."

With that grim or hopeful declaration, he took a step closer to Bruce again, and Bruce let out an angry yet defeated-sounding sigh. It wasn't like he was going to get more infested, now, and he just couldn't find it in him to punch is former friend. He'd show Jessica and Kevin that it was possible to resist. He barely felt anything so far, and if this was what everyone had been so worried about, Bruce realized he must've grossly overestimated the willpower of the average idiot.

“Yeah, just relax," Jake murmured, noticing Bruce's posture relaxing and his nose twitching. He took another step, stroking his cock as he watched. Seeing it happen to someone he knew, and especially knowing he was the cause of it was beyond erotic, and the slug bonded with his own brain made sure to reward him in spades with pleasurable little jolts and shivers. “Let it happen. Gimme a big happy sneeze!"

Bruce rolled his eyes. He was starting to suspect that the whole sneezing thing had just been an excuse for people to let go of their inhibitions. He didn't feel wrong at all. In fact, the sense of warmth in his head was feeling really nice. If only it wasn't for his nose itching like crazy. Suddenly, his breath hitched, a look of concern flashing across his face.

“Just one sneeze and you'll feel a lot better," Jake giggled.

Bruce had to let it out. He had enough presence of mind to cover his face when he did, with a loud ahh-tshew. Immediately, an immense sensation of wellbeing washed over him, a kind of warm relaxation, like that one sneeze had fixed everything, relieving the immense itchiness.

Jessica and Kevin stared, unable to do anything without entering into the range of their sneezes and the faint pink mist still lingering in the air, watching the perverted display unfolding before them. They were, in a way, just as frozen in place as Bruce watched as they watched him slowly succumb to the infection.

“There you go, feeling any better yet?" Jake goaded his friend.

“Uh…" Bruce stuttered. He began to speak and immediately forgot what he'd been saying. As he removed his hand, he noticed his palm was covered in pink, which was certainly something he should've been worried about, but then, he suddenly sneezed again, more violently this time. The happy, relaxed feeling intensified as a mist of pink exploded from his nose, and it felt like it took most of his worries with it.

“Aww, look, you're getting all excited," Jake exclaimed happily. He was standing right in Bruce's face. When had he gotten that close? And what was he talking-

Jake's hand grasped the obvious bulge in his jeans, and Bruce let out a loud moan as fireworks of pleasure went off his head. He couldn't believe how good it felt. Had it really been that long? Was he that pent up?

Another sneeze, and more of his thoughts were shaken loose, leaving only that happy, horny feeling.

“Want me to take care of it? Mhm, does Brucey boy need a warm mouth around his cock?" Jake grinned, already clumsily working on undoing his belt.

Bruce watched, with a blank stare, at a slug slowly crawling up Jake's neck. He clearly remembered that the slugs were bad, but it looked pretty harmless and all colorful. As he stared, the colors seemed to shift as the slug moved, its body undulating and throbbing like a…

He felt a warm hand grasp his bare cock. A quick glance down showed that his pants had been undone, his cock was out, and Jake was stroking it eagerly. Bruce's hips twitched with excitement. He really needed to fuck, but more than anything, he was struck by how sexy his cock looked, all hard and eager like that, with clear precum slowly drooling from the top. God, his balls ached with need, feeling so very swollen. There was just that slight gnawing worry in the back of his head, something about definitely not wanting to do this with Jake in particular, and he recoiled in spite of how good it felt.

“Oooh right, I almost forgot," Jake smiled. There was genuine affection in his voice, even if it was fuelled by the infestation. “You need a feel-good slug first. Mm… this little guy," he murmured, plucking up one of the smaller ones that'd been slowly crawling up his shaft. He held it up for Bruce to see. “He's gonna go into your ear and then you'll feel all fantastic. Then I'll suck you. Deal?"

What- what am I supposed to be- god, it's like I can't think-

Jake held the colorful little slug closer to Bruce's ear. He could hear someone shouting in the background, but they seemed muted and unimportant. Still, he knew for absolute certain that a slug going into his ear was bad, so he-

He sneezed again, spraying Jake's face with the pink goo. Jake giggled, and Bruce moaned, not seeing any reason to bother wiping up the funny-looking string of snot dangling from his nose, letting Jake caress his ear with his slimy hand. That sneeze almost felt like an orgasm, but somehow his head felt clearer. All those worries were totally gone, and the feeling of something wet and slippery nudging into his ear – quieting those cries he heard in the distance – made him giggle.

There was the weirdest sensation of immense pressure, and a brief pop that made him wince, if sluggishly, but then he couldn't hear anything at all except a kind of wet slippery sound in his right ear, sounding sort of like a cock slowly sliding in and out of a really, really wet and excited pussy. The thought made his cock throb again.

“There you go, now just wait a little moment," Jake grinned, and knelt in front of Bruce as the slug's tail disappeared into his ear canal.

Kevin let out a gasp, as if he'd been holding his breath. Jessica stared, with her mouth feeling dry. That was it for Bruce, and they'd done nothing to help. There'd been nothing they could do without getting infested themselves, she told herself, trying to relieve the overwhelming feeling of guilt. Kevin leaned against her, and she leaned back, the two of them relying on each other for support. What were they supposed to do now? Bruce had been the muscle of the group, and without him, they'd be easy pickings.

Kevin suddenly realized that he was getting hard watching it. If not before, then when Jake's plump lips closed around Bruce's throbbing cock. He covered his crotch with his hands and noticed he was shaking, too. He hadn't expected it to look so erotic and passionate, and least of all so alluring. His thoughts wandered to how it'd feel, and then a realization so very perverted that he almost felt nauseous, his stomach tying itself into a tight knot; he wanted it. At least in some kind of sick, kinky way. He wanted to get sneezed on, and then sneeze his brains out, and finally have a slug crawl into his ear and take control.

Bruce was already past the point of really wanting anything except more of those soft, warm lips caressing his swollen length and the tongue lavishing his frenulum and glans with quick, feathery licks. But there was a specific moment where he truly lost himself to the rapturous pleasure. Colors swirled over his vision, no doubt as the slug finally reached his brain and set to work bonding with it. It was, in a strange way, a beautiful sensation. Like his eyes had been opened, truly, to how beautiful cocks were. His thoughts were like a sluggish slideshow of what was happening, each followed by an intense surge of blissful, almost electric pleasure surging down his spine. One moment, he was practically drooling at the thought of sinking to his knees and sucking Jake's cock in turn, and the next he was doing it, feeling that grotesquely big cock stretch his lips side. It tasted like candy- no, like fine champagne, both the precum eagerly bubbling from the cumslit and the slime a slug left across his tongue as it left Jake's bloated balls and crawled into his mouth.

At the same time, he felt his cock growing and growing as he thrust, feverishly, into Jake's warm, wonderful mouth. First an inch, then two, and he was getting thicker too, reshaped into a perfect host. Then he was swallowing a thick mouthful of sweet, warm cum and the slug along with it as Jake's beautiful cock jerked and bucked in his mouth, his head flooding with hazy euphoria as he obeyed his new desires. Something thick was pressing against his own cockslit, and then into it, and he knew what it was. He didn't care. Bruce wanted to have his balls filled to the brim with those sexy feel-good slugs, and dutifully he stopped moving his hips so it could enter him. A few agonizingly slow minutes passed as his urethra expanded around it, allowing it inside his body, deeper and deeper – and then, another pop of relief as it finally reached his… balls, his bladder, Bruce didn't even know, but he felt that warm glow intensify even further and then he was cumming too, pumping what felt like gallons of cum down Jake's clenching, clutching throat.

Kevin, from where he was watching, could barely keep his hands from his cock. Watching Jake and Bruce grunt, groan and twitch as they filled each other's mouths with cum was touching on something inside of him, feeding into a desire he'd never even thought about wanting, but he did. It'd be so easy, too. All he really had to do was approach them and soon he'd join them in their ecstatic, hedonistic revelry as just another oversexualized slug-host. And he'd have a huge cock just like them, one that he could easily milk dry into his own mouth when there was nobody else to play with.

He wasn't infested, yet, but the idea had taken root in his mind, and it was getting harder and harder to dislodge. He held on to Jessica tightly, as if trying to steady himself against that tide of horrible, forbidden desire, but then, Bruce looked up at him. Cum drooled from the corners of his mouth, and his eyes expressed only a glazed-over, all-consuming lust that practically beckoned him to join. His eyes screwed shut and he sneezed freely, splattering the floor in front of him with both spilled seed and that pink goo that'd so easily infest Kevin, too.

The results of the infestation were a little unpredictable. Some became breeders of a kind, so swollen that they struggled to move much. Others, like Jake, seemed to stay relatively mobile and would have the role of infesting new hosts. Kevin, naturally, wondered what he'd become if he let it happen – Jake's slurred, lusty words still rang in his ears – but neither of the two fates seemed awful to him, now. Surely a life drowning in bliss was better than barely scrouging by, scavenging the scraps of civilization?

He stood upright and took a step towards his two infested friend, only for Jessica to grab his arm in a panic.

“What are you doing?" she hissed. “Death wish much? If you get any closer to them, they'll sneeze on you and then you'll be sucking cock with them. With slugs crawling in and out of your poor cock."

“I know, I know… I'm sorry, Jess. I kinda want it. I'm just tired of barely getting by and worrying all the time," Kevin sighed. He was still rock-hard in his pants, too. He wasn't saying anything about that yet. “Look at how happy they look."

“Yeah, because they both have slugs probably eating their brains," Jessica shot back. “Come on, I'll let you fuck me if you need it that badly!" she offered, in desperation, as he saw Kevin glance at the two again. They were spent, but it wouldn't take more than a few minutes for them to recover. “We have to get out now."

“No. I've made up my mind. I just can't keep living like this. Especially not without my friends," Kevin sighed. He wrested his arm from Jessica's grasp. “Please forgive me. Or join us later so you don't have to."

Jessica fought back the tears as Kevin unceremoniously undid his pants, letting them fall around his ankles, and then peeled off his underwear, too. She was shocked to see his cock spring out, fully erect. Yes, she had fantasized about it too, but so had probably every survivor. She'd never once considered actually letting it happen.

“Please don't-“ she stammered, but Kevin was already walking towards Bruce and Jake, not making any attempt to hide his desire.

“Ooh, look," Jake cooed as he watched Kevin approach, in that fucked-silly tone of his, when he finally pulled his head off Bruce's cock. “Someone got all hot and bothered watching us. Wanna have fun?"

He stood up, his chin and chest both splattered with Bruce's cum, and another slug slowly emerging from his bulging cock. Bruce was a little slower to react. “Oh, doncha worry about him. It takes a while before you get going after being infested," Jake smiled.

To his surprise – he hadn't anticipated just how eager Kevin was – his friend slowly sunk to his knees.

“Go on, do it. Please. Make me all dumb and horny," he spoke, in a hoarse, strained tone, one that betrayed that he was wrestling with his desires.

“Oh honey, I will. Don't worry, just open wide. Be sure to breathe real deep," Jake murmured. By now Bruce was up on his feet too, his newly enlarged cock now standing just as impressive and sexy as Jake's. It'd be little while before he could actually give birth to any new slugs, maybe. Nobody really knew how long it took.

Jessica was still whimpering and pleading in the background, but Kevin closed his eyes and tuned her out. This is what I want. Goodbye math, goodbye overthinking and worries, he told himself. He opened his mouth and began to breathe deeply, through his nose, facing up towards those wonderful cocks. God, he could smell them. The infested seemed to have this intense musky scent of pure lust around them, mixed with something flowery.

“Ah, here it comes," Bruce huffed, his breath already hitching as that now very enjoyable itching in his nose intensified. The thought of what he was really doing never crossed into his mind. He was only following instincts and pleasure.

Jessica couldn't watch any more. She turned around, covering her face with her hands as she heard two sneezes in quick succession, followed by happy, brainless moans. She felt dizzy, trying to focus on her next course of action, but what could she do? Maybe if she just hid until her friends were done, she'd be able to sneak out, but where could she go all alone?

Behind her, Kevin was inhaling the pink mist greedily. It tasted a little bit like cotton candy to him and knowing what it'd do to him had him raging hard. With it splattered all over his face and even tongue, there was no going back anyway, and he was determined to enjoy the moment. He didn't resist the building itchiness, and a few minutes later, when his first sneeze came, he almost seemed proud, a liberating emptiness settling over his thoughts as it happened.

“Ooh, wow, this feels… really good," Jessica heard him groan. She was already moving away to hide in one of the patient rooms. “Come on Jess, join us," Kevin called out, and she froze again in disgust. How long had Kevin been fantasizing about this?

Dutifully, Bruce offered his massive cock for Kevin to suck on – an offer he took eagerly – while he guided one of the many extra slugs into his ear. He giggled around his tasty mouthful of infested meat as he felt it slithering inwards, sneezing freely over Bruce's cock only to clean up his own mess with his tongue.

Jessica let out a scream as she felt a hand grasp her wrist, spinning her around. It was Jake, of course, having left Bruce to handle Jake. She yanked as hard as she could, managing only to hurt her shoulder.

“Please don't panic," Jake slurred. He seemed even dumber now, barely able to find the right words. “We'll make you feel really good."

Then he tugged, and Jessica had no choice but to stumble towards her three former friends. His grip was like iron, pulling her inexorably towards her doom as she flailed and tried to grab onto anything in sight to maybe get enough leverage and momentum to free herself. Yet there'd be no sudden rescues or miracles.

Jake pushed her to the floor, firmly but oddly gently, making sure that she got an eyeful of Kevin and Bruce rubbing their cocks together, moaning – and quite frequently, sneezing – as a new-born slug crawled out of Bruce's cock and began prodding for entry into Kevin's. They all looked so painfully hard, and he was already getting bigger too. Jessica pulled her shirt over her face and took a deep breath, hoping that the fabric might filter out the spores.

“Guys," Jake giggled. “Let's get her done before we suck any more tasty, sexy cocks. She's all sad and afraid. And she can make so many more little friends for us."

Jessica shivered at that notion. They were hoping she'd become a breeder. It happened to women more than it did to men, they were right about that. She struggled, kicking and punching to no avail as all three focused their attention to her. It was short and brutish, Bruce tearing off her shirt and then her bra while Jake focused on peeling her pants off, and Kevin – the newest infested, and the only one who was still even slightly human – straddled her chest, looking down at her alarmed face.

She had managed to get another deep breath before her shirt was ripped away from her, and she was still holding that, watching pink snot drip from Kevin's nose.

“I promise it- mhh, it feels great, Jess," he panted. There was still cum on his lips too. Bruce must've been very excited about his first conversion. “Please don't worry. You'll un-nff-understand in just a moment."

“Yeah, no need to be afraid," Jake smiled. He pushed her left arm against the floor, and Bruce did the same to her right one. She squirmed, feeling one of the slugs already crawling up her bare leg and towards that vulnerable and somehow damp slit between her legs. Another one had fallen on her chest, leaving a slimy trail between her breasts as it made its way towards her head. Her ear. Where it'd crawl inside and take over, leaving her a mindlessly horny bimbo or worse yet, a mindless breeder for all of the infested to pump cum and slugs into whenever they wanted.

Jessica shivered. She watched as Kevin's expression melted into something relaxed and horny. A drop of the pink goo fell down, splashing perilously close to her own nose. She could see Kevin's cock growing, naturally slotting between her breasts, throbbing and drooling precum over her, and not only that; she could feel his entire body twitching as he tried to hold back another sneeze. No doubt trying to time it so she'd be breathing in right at the moment it happened. Already, Jessica was struggling to keep holding it. There was only one outcome, unless someone suddenly ran in and pushed them all off her. A non-existent hope, but she had to cling on to something, anything.

The slug between her legs had reached her inner thigh, now, and the other one was halfway up her jawline. The need for oxygen was burning in her lungs, but the moment she breathed in, she was doomed.

“We're gonna stuff your womb full of slugs and cum," Jake giggled. He sounded like it was something playful and fun, rather than the erasure of her mind as a human. “They'll use your body as a breeding ground and you'll just love-“ he stretched out the word love “-giving birth to more".

Thoughts of the disgusting slugs mating inside her – which seemed to be what the lust-addled Jake meant – made her squirm even harder, trying her utmost in a final push to shove Jake off her. In doing so, though, she burned through the last little bit of oxygen left in her lungs. Stars danced at the edge of her vision, and her field of view was narrowing. Time was beginning to move in odd leaps as her body wrested away control from her brain. Jessica watched as Kevin's chest expanded, and then he sneezed freely over her face. Bruce mumbled something, and for a brief moment, Jessica felt triumphant; she'd outlasted him, and soon the mist would've settled enough for her to take a safe breath.

Then she realized that her vision was already returning and watched her chest heave. As fresh oxygen flowed into her body – along with the pink mist – she realized, to her horror, that she was already breathing and had gotten a good nose and lungful of the stuff. The moment she could muster it, she screamed, thrashing from side to side as much as she could. Maybe if she was quick enough to get free, she could run away and survive the mind-numbing effects.

But that warm, tingling, itching glow was already spreading up her nose. Then Jake sneezed too, and with a gasp, she inhaled even more of it. No no no. I'm not going out like this, I'm not-

Jessica was practically hyperventilating in panic, and despite knowing it was only making the situation worse for her, she couldn't stop.

“Calm down, let it happen…" Kevin murmured, caressing the side of her face, while she recoiled in disgust. “You'll feel better the moment you sneeze."

To her surprise, Kevin snatched up the slug that was tickling at her earlobe, holding it in place. As if he didn't want it to enter her before she was appropriately dumbed down. All she had to do was resist it. The pink goo didn't seem to do anything before the victim sneezed, after all. Her eyes were watering at how intense the itch was growing, though, that familiar pressure – almost like an orgasm – building up in her sinuses.

Jessica held out as long as she could against the inevitable, and then, she sneezed several times in rapid succession. Her thoughts quieted down as she absentmindedly watched the swirling cloud of pink. I'm still me. Three times three is nine-

She sneezed again, and this time she just couldn't stop. She kept inhaling more of the pink mist each time she breathed in after a sneeze, and with each one, her mind felt a little calmer as those worries left her thoughts, blown away like fallen leaves. She wasn't fully aware of being reposition, but then, Kevin was cradling her against his chest, comforting her, stroking her hair as she sneezed her brains out, one unpleasant thought at a time.

Jessica felt someone's fingers brush over her naked pussy. She didn't mind. It felt kinda nice, really.

“God, she's so wet," someone – probably Bruce – giggled, as she couldn't help but agree. It was only natural to be horny when this close to all of her best friends, after all. She nudged her legs a little wider, knowing just how much they liked looking at her sexy little cunt.

“Told you," Kevin murmured, and then placed the slug back right on her ear. It quickly slipped inside, and all Jessica could think about was how nice it felt, all slimy but quickly warming up as it crawled into her vulnerable ear canal.

As she watched, Jake returned with an armful of slugs. All the ones he'd given birth to in the patient room, she realized. Oddly, Jessica felt as if that thought should've sparked some kind of alarm inside her, but instead, she just felt increasingly horny.

“All for you. You'll get a bit more than us," Jake smiled, and Jessica smiled back, not really having any idea what her friend was even planning. She just wanted to stay like this forever, all warm and hazy and not caring about a thing except feeling good.

There was a pop deep inside her head, and she let out another high-pitched giggle, marvelling at just how neat it felt. She could just barely feel movement deeper and deeper, and then, nothing at all.

“Hee. So is that-“ she began, and then her jaw went slack as colors began to shift and intensify in her vision. “Ooh they're so pretty," she exclaimed, suddenly seeing the slugs in a new light.

“Right?" Kevin smiled. “Perfect little feel-good friends, and you're going to have all of them loving each other inside you."

Her immediate, visceral reaction was caught and quickly rewritten as the parasite worked on her brain. Instead of disgust, her pussy clenched with desire. The thought was really sexy, the idea of all of those cute, sexy slugs squirming around inside her and having a ton of fun fucking each other. Speaking of that, she was really starting to feel like she could use some cock of her own.

As if he was reading her mind, Bruce flopped his massive cock onto her face. She stared at the beautiful length. He was so big, too. “Mmm," she moaned, and then wrapped her lips around the tip, almost gasping at how good the incredibly hot, masculine flesh felt against her lips.

At the same time, Jake knelt between her eagerly spread legs and held a handful of the slugs against her quivering pussy, where they quickly began to slither their way into her. She moaned happily around Bruce's cock, shamelessly slurping at it as Jake fed handful after handful of the colorful slugs into her. She felt each and every one as they painlessly made their way deeper into her and then, painlessly, past her cervix and into her womb.

“Nff, more, gimme more," she begged, taking a break from her oral worship for a brief moment before latching her lips onto Kevin's cock instead, keeping her hand on Bruce's so she could keep stroking it. The only thing to interrupt her was when she felt a rough, slimy hand cup her breasts. A quick glance down – without ever stopping her sucking – revealed that her breasts, her boobs, were growing too. The sight made her feel really sexy, and they felt really sexy too. All the better for cute boys to suck on while they fucked her. Probably really good for luring in those silly few who didn't have a slug-friend of their own yet.

Her belly was already bulging, and the sensation of the slugs squirming around inside her, probably already mating, made her want it more and more.

Jake said nothing. When he ran out of slugs, he positioned himself between Jessica's legs and sank that enormous cock inside her. It didn't even hurt! She felt so proud of herself for taking it so easily. Taking lots of cock was important after all, because the slugs inside her fed on the cum. No wonder all the other infested were so eager to get fucked all the time! She felt so dumb for not realizing it earlier, but there was no time to worry about that when she could be doing her duty instead!

Bruce and Kevin came at the same time, their cocks suddenly jerking. One in her mouth, and the other in her arm. She moaned at the sensation of cum splattering her face and more bathing her tastebuds in the sweet, delicious flavour. With a grunt and a buck of his hips, suddenly Jake was cumming too, and feeling that sticky, wet heat pump into her pulled her right into an orgasm too. She moaned in ecstasy, drooling cum all over her massively swollen new tits, as she was finally seeded by her best friend. And soon, the other two as well. Time really didn't matter much when she was constantly getting filled by one or several of them.

A few hours later, Kevin returned with a long line of the infested in tow, all with big sexy cocks. Jessica licked her lips and spread her legs wider, showing off her cum-drooling pussy and the slugs happily crawling along it, offering herself for them to enjoy. They looked spellbound by the sight of a breeder, and eagerly formed a line in front of her while Kevin held her hand. Her belly was swollen enough that she looked several months pregnant, but that only made her feel better about doing her job.

As the first of them sunk their amazing cock into her clenching, soaked pussy, all she could think about what a great breeder she was.
