It was one of those days. The kind of day where Tom had nothing to do, and ended up slouched in front of his computer, his feet on the desk, pants comfortably unbuttoned, and absolutely nothing worth getting up for. He wasn't a slob, no, it was just that he was entirely done with his schoolwork for the week, the apartment was already clean (or clean enough) and none of his friends were available, neither online nor offline.

In a way, it was refreshing. But of course, for someone his age, idle hands do the devil's work, and soon enough, he was idly browsing first porn, and then, deciding that he didn't really feel like masturbating, sex toys. Tom had been thinking about getting a, as the website said, male masturbation aid. A cocksleeve, in other words, but he hadn't quite seen any that grabbed his attention.

Well, until now. There was something new in stock. He clicked on it with half-hearted interest. The "Wet Squeeze" model, which according to the description, would take care of everything for him. Magic and technology in perfect harmony, this model had it all; a stimulating inner core, bound by a strong enchantment, and the materials to support it. All he'd have to do was sink his cock into it, and it'd "hug your penis like a loving partner, teasing and stroking," and best of all, it didn't require any cleaning!

Like he insisted, he wasn't a slob, but he was a young man, and cleaning wasn't exactly a passion of his. Well, he figured, if it does even half that it has to be worth it. Granted, the price was steep for what he'd only use for a singular purpose, especially given his relatively tight student budget, but he was sold. Really, it was the lack of manual cleaning that really convinced him. He clicked order, and then, same-day delivery. Life had been so much easier since magic entered the world. The store would only have to find his product in their warehouse, and then it'd be teleported to his doorstep, marked with a personalized mail-glyph. And it only cost a few dollars more.

Still, it'd take some hours. Orders had to be processed, after all, so he slumped back into his worn chair and continued the day's business of doing nothing. The problem was that ordering that new toy had him too excited about using it to do his usual do-nothing hobby, namely masturbating.

Yet, eventually, it was there, with a chime on his phone alerting him that it'd arrived. Tom practically pounced out his chair and raced to pick up his package, wasting no time in tearing it open. There it was, the outer casing a shiny metal with a few decorative runes on it. It felt heavy in his hand, as if full of liquid, with an audible - if faint - sloshing as he shook it. He figured it was some kind of jelly used to make it a more pleasurable experience.

Tom looked through the rest of the parcel. There was a vial of something, reading, "Insert into sleeve if not used for a week". Some kind of preservative, he figured, and tossed the manual aside. Why'd it even come with a manual, and what would that manual say? "Insert cock, optionally move sleeve up and down until orgasm occurs"? Ah, well. If there was no manual they'd probably be liable for someone accidentally swallowing the whole thing.

The toy's opening was shaped like a mouth, and as Tom pushed against it with his fingers, he was amazed at how lifelike it really felt. Slick and warm. That must've been the magic aspect of it, the toy produced both lubrication and heat, it seemed. Ah, he didn't want to wait any longer, he was already hard at the idea of... using a sex toy. It had a pleasant scent to it and all, kind of like- he couldn't quite place it, but it seemed to tickle in his nostrils.

Tom quickly disrobed and leaned back on the bed, thinking about what position would be the most comfortable. If he didn't have to actually move his arms at all, as advertised, he figured he'd pin the toy beneath him and just imagine he was fucking a real human. His cock didn't seem to care much for if it was real or not, with how stiff it was as he rubbed his glans against the surprisingly fleshy opening. It sent a shiver of delight down his spine, and in moments, he sunk into it.

It felt amazing, a warm slickness that seemed to squeeze every inch of him. The sensation was almost overwhelming, as if someone was licking his cock while he was also buried inside of them. A groan spilled from his lips. Fuck, he wasn't going to-

The toy squeezed him in a quick, eager rhythm, and Tom, pent up as he was, came immediately, moaning and gasping for air as he fed the toy the first plentiful load of his cum. He was grinding against it, driven by a single-minded desire to bury his bucking cock even deeper into it, to plant his seed as firmly as possible-

And then, reality set back in. Wow. His taint was sore from how hard he'd cum, and when he withdrew, his shaft was entirely clean. It worked exactly as advertised, and felt beyond good too. It was hard to put into words, but it'd felt like something was stroking his cock, not missing a single inch.

That day, Tom used the toy until his balls were so dry he simply couldn't anymore, nor could he get hard no matter what he tried. All in all, a perfectly enjoyable day of nothing, he thought. And mess-free too. Granted he'd forgotten to make dinner while mating with his new wonderful cocksleeve, but he could always order a pizza. Or two, with how many calories he'd surely burned. Almost immediately after eating, he fell asleep, as exhausted as being thoroughly milked had left him.

Yet, he fell asleep with his cock inside the toy. The manual said something about that, yet it was sitting unopened on the floor, and Tom in turn blissfully unaware.

The toy was powered by a captured slime, of sorts. Not the common green ones that one might find in their garden, nor the noxious brown ones often dredged out of sewers in the place of rats after the dawn of magic. No, inside the sleeve, a white slime was imprisoned. It wasn't a sentient being, nor did it really mind its captivity - after all, it was being fed plentifully - but the magic binding it was flawed, only slowing down its natural behaviour.

With Tom asleep, it had all the time in the world to explore his shaft. Slowly, the slime enveloped him all the way to where the sleeve ended. It couldn't exit its prison, but it could move around freely within it. A tendril caressed the slit where its last meal had arrived from, flicking over it, and then dipping in, searching for more. Normally, the slime would infest a victim in order to reproduce, but the enchantment prevented it from doing either. Instead, it merely explored with instinctive curiosity, that probing tendril narrowing as it sunk deeper into Tom's body. The chemicals it exuded always had an aphrodisiac effect, but when it felt necessary, it could produce a mild relaxant as well.

They were, after all, magical beings. What'd normally have caused great discomfort didn't even wake the horny, sleeping man, as the slime slowly relaxed every valve and sphincter within him, slipping through one protective barrier after another, and there was nothing his body could do to stop it.

The slime found Tom's bladder, at some point. It slipped as deep into his balls as possible, at the same time. Both, it recognized as desirable new homes. Due to the presence of cum - the white slimes primarily fed on the stuff - the balls more so, even if access would prove difficult. Yet neutered as it was by the enchantment, it could do little else but explore, and stimulate, seeking to feed once more. Tom was drained, however, and soon the slime withdrew with a quiver of disappointment, leaving the man's body to himself well in time before he'd wake up.

Over the next few days, he grew what many might call an addiction to the toy. It felt too good, so each time he was in class, Tom would be fantasizing, his cock stirring happily at the thought of getting to sink into the toy again. When he finally got home, before doing anything else, he'd slide his shaft into that wonderful sleeve, letting to squeeze and massage him to heights of bliss that left all worries feeling distant and unimportant. Sometimes, he used it several times in a row, or just let it keep sucking orgasm after orgasm out of him, until he passed out. Each time, the slime explored his body, almost longingly, as it prepared everything for an eventual infestation.

It wasn't anything Tom noticed, but his urethra, along with all the parts it connected to, were more distended, more flexible. More ready_for his future as a slime-host. Of course, the enchantments wouldn't let that happen, even though the manual _did say to not stay inside the toy for prolonged periods of time.

One morning after a particularly long-lived night of fucking his beloved toy, when Tom woke up, he'd forgotten entirely about what he did last night - just having that vague glow of satisfaction radiating through his body, along with a fierce arousal - and so he rolled over, the sleeve slipping off his cock and clanking as it hit the floor.

Fuck.

Forcing himself awake, Tom picked the toy up. There was a visible, if thin, crack through one of the runes, but at least it wasn't leaking or anything. He desperately hoped it was still okay, because despite the scare, he was still painfully hard. Tom didn't know it, of course, but that was because of his friendly little pleasure-slime; in the wild, they kept their prey desperately aroused to force them cum as much and often as possible. When the white slime had explored his body, it'd left a thin layer of that lust-inducing stuff over every inch of his tubing.

What's the worst that could happen? It's just a little crack, Tom told himself, failing to think about reading the manual, distracted as he was with both panic and arousal.

The toy looked fine, all in all. What Tom didn't know was that one of the enchantments had broken, and not just any. The most important one that prevented the slime from leaving the toy. Once outside, it'd no longer be subject to the others, either. Yet it had no good reason to leave immediately; the outside air was dry, and being a parasite of sorts, the slime wouldn't survive for long in the open.

Maybe I'll just give it a quick go, Tom reasoned. If it hurts I'll just return it, right?

He just needed some quick relief, and so, he soon positioned his swollen cockhead at the toy's opening again, and slid inside, groaning in bliss as that slimy wetness engulfed him again.

The slime inside recognized the possible host immediately, but it was happy to bide its time. If it tried forcing itself into a conscious host, chances were that it wouldn't survive their reactions. It was almost ready to reproduce, only needing a little more nutrition - and so it set to its task with gusto, wrapping its body around the cock protruding into the toy, and squeezing, massaging it in anticipation for its next meal.

Soon, it was rewarded with a fresh spurt of the young man's cum, which briefly formed a dense cloud within the slime's body before being quickly absorbed. It didn't stop. Tom was easy to please with how high his libido was, and with every orgasm, he felt more needy, if anything. He kept whimpering, all but unable to move as his next climax was even stronger, though he only produced a few watery spurts of cum. The slime didn't relent before Tom's shaft began to go limp despite its ministrations.

Thoroughly exhausted, Tom tried to stay awake - he did_have classes to attend today - but after too many orgasms to count, his eyelids felt entirely too heavy. _Maybe I'll just have a short nap, he thought, his head feeling rather empty.

It was exactly what the slime had been waiting for. It waited, wrapped around Tom's limp cock, feeling for his breathing and heartbeat. Once it was sure he was asleep, it began its task, unhindered by the clumsily broken runes. A new host. It'd latch directly onto his balls and drain his cum as it was being made, soon enough. But first, it needed to secure its new home.

It flattened and narrowed its body, slowly squeezing in through the host's unresisting cockslit, absorbing leftover cum as it went, deeper and deeper. Infesting the testicles was difficult, and took quite a while, but the bladder was easier to access. It had a nearly solid core that it left until the very last moment, the size of a goose egg. The amorphous part of its body expanded, slowly and painlessly dilating Tom's urethra, forming a channel of sorts for the core to pass through quickly.

Tom did still feel the moment if pushed through his cockslit. There was an overwhelming sensation of pressure that knocked the air out his lungs, and a kind of white-hot pleasure he'd never felt before, all at once.

He groaned, yanked the toy off his cock only to see a bulge travelling down his urethra, and the last of the slime disappearing into his body with a wet slurp, before he could do anything about it. He had heard_about slimes infesting people before, but actually seeing it happen had him horrified. Where'd it even come from? He groaned, running to the bathroom in a vain attempt to pee it out, but to no avail; nothing came out. Rather, intense pressure sunk deeper, until he was writhing from the sheer discomfort, barely able to breathe as it reached the base of his cock, and then - _pop. The pressure eased, but he felt a kind of weight settle in his bladder. That was it, then, the slime's core was safely inside him. He felt like he needed to visit the bathroom badly, for a few moments, until the relaxant effect of the slime took hold. The rest of it escaped inside him with a wet slurp.

Only moments after reaching safety, the slime began the slow process of claiming the smaller spaces of its new host's body, intending to entirely hijack his sperm production for its own reproductive needs. It focused on the prostate, gooey tendrils infiltrating every inch of him, and the only thing Tom could feel was a strange warm thrumming, for now, somewhere deep behind his cock. His prostate, he realized. It wasn't unpleasant, but he wanted the slime out. His belly was bulging ever so slightly from the volume of his new passenger, which nearly made him freak out again. Calm breaths. Deep breaths. In... and out.

When Tom had calmed down - as much as he could, anyway, given the circumstances - he realized he was getting hard again, his body happily absorbing the aphrodisiac the slime was oozing with. He vaguely recalled that being a defense mechanism, in order to keep the host too distracted and pleasured to even attempt to get rid of his new passenger. While it'd been strong just applied to his cock, with the slime suffusing his entire body with it, it was almost unbearable. In other words, when his thoughts kept flashing to just masturbating more, or even finding some random guy to fuck on the street, it was working just as intended.

He picked up his phone in a hurry. If this wasn't fixed quickly he'd entirely fall under the parasite's control. The fuck was their number- oh! He finally picked up the manual and flipped it to the first page. There, the manufacturer's number. They had to have some good advice. He moaned out loud as his cock throbbed with excitement, even as he was dialling the number.

"Welcome to Magic Adult Toys, how may I help you?" a bored voice on the other end opened, and Tom grit his teeth to stop himself from moaning again as the slime squirmed inside him, seemingly seeping through all the tubing he had.

"Hey, so, uh, I kinda dropped one of your toys and the next time I used it-" Tom replied.

"Did you read the manual?" the person on the other end spoke, in the same bored monotone.

"No but I mean, I just dropped it and then this fucking slime-" Tom argued.

"The manual, did you read it?"

"...no," Tom finally sheepishly admitted.

"On the second page of the manual, it clearly states to not use the toy if it has been damaged, and that we are not responsible for any damage to the user that may result from such an action. Have a good-" the other explained, his voice never changing even a single pitch.

"-wait no, at least tell me how to -nnh- get it out!" Tom pleaded.

"You don't. Or you have surgery. There is a fair bit of money in being a slime incubator, though. But you'll need to call our manufacturing department for that. Yes, have a good day," he finished, and immediately hung up, evidently tired of dealing with customers who didn't read the manual. Or any customers at all, really.

What was that about being a slime incubator- nnngh!

Tom cried out as a the slime squirmed inside him. He had no idea what it was doing, but there was a kind of pressure over his prostate, one that left his knees feeling weak. He fell back into the bed, writhing in increasingly overwhelming pleasure. No, no, get up and call the hospital, come on Tom, you can-

Another vibrating, wet squeeze somewhere deep inside him. His cock throbbed and bucked, and if it wasn't for the slime absorbing every drop of liquid he produced, he'd have been leaking. Was it going to keep doing this forever? He'd never be able to move if he was just going to cum over and over again, Tom realized - but there was a kind of hazy-minded ecstasy to every thought, a silver lining that he'd at least be in a permanent state of bliss. Until he starved to death. It couldn't let that happen, could it? The slime needed_him. The question was if it _knew that.

The phone fell out of Tom's hand as his back arched, another intense orgasm seizing him. This time nothing came out at all, despite the familiar, ecstatic convulsions. Another one followed, and then a third, until his eyes were watering from overstimulation. Then, mercifully, the massaging inside him stopped, the slime's hunger for cum sated. For now. He didn't dare guess for how long.

On the one hand, that had been one of the most pleasurable orgasms he'd ever felt. His prostate was positively glowing inside him, radiating with that warm, fuzzy satisfaction. On the other, if this was going to happen often, there was no way he could be productive at all. And then, if he remembered what he'd read correctly, the horrible thing would migrate into his balls to begin feeding properly. Tom imagined his soon-to-be fate as a pleasure--drunk slime--host.

He paused for a moment, taking a deep breath. The customer service guy had said something about the slimes being profitable. He wasn't entirely sure if he wanted to be reduced to that, but it certainly was pleasurable - at least, his tingling body seemed to think so, influenced to no small degree by the slime feeding its chemicals into it - and if there was money to be made, too... there was some appeal to- no. That was his mind slowly being warped by the constant influx of pleasure. But he decided to at least call, maybe if he let it split a few times he could make enough money for surgery to get it out.

That line was entirely automated. And thank god for that, Tom sighed quietly. It meant he didn't have to worry in case his "passenger" suddenly woke up again.

"If you would like to hear about our business, press one. f you would like to become a slime breeder, press two," the robotic voice spoke. "If you are currently the host of a white slime, press three."

Tom pressed three.

"Congratulations!" the voice replied, with zero enthusiasm. "Being a slime host can be a wonderful experience. If you are interested in making money with your new friend, remember that we pay up to $100 per slime core that you ship to us."

$100? That'd make for some decent pocket money. The call continued, telling Tom how to ship said "slime cores". A well-packaged mason jar would do fine. And he'd have to attach his personal details.

Almost as soon as he had read that, the strange internal massage began again. Oh no. Tom tried as hard as he could to fight it, but soon he was on his back on the floor. With how thick the slime was, his body couldn't quite pump it out, but it tried, those muscles getting an intense workout each time, and each time he had another orgasm it only felt more intense, his cock throbbing with newfound strength. The slime was taking care of that, too, slowly infiltrating more and more of his body and making sure nothing tore. It wanted the host strong enough to ejaculate a core, after all, ideally into a new host.

After a few dozen more orgasms, the slime allowed him to rest for a longer time, having successfully given its host enough of a workout that he'd be good at turning other people into hosts, too. That, and despite its lost mass, it'd had plenty to eat. Enough so, in fact, to proceed with the next part of its lifecycle.

In that downtime, Tom finally began to think about how he might get rid of it. Yes, the money was appealing, but he didn't want_this, did he? He could feel the damn thing squirming around somewhere deep inside him, seminal tubes relaxing as the slime's excretions soaked into him. It was going to be migrating to his balls soon, he realized, and at that point there'd _really be no way of getting rid of it without surgery.

It wouldn't come out unless it sensed a host, even once it had reproduced. And if it didn't, he'd feel increasingly pent up, until it was unbearable. Until he went to some club and just fucked the first thing that allowed him to, giving them their own happy little friend. Unlike some other parasites, though, the slimes never really took control of their hosts, relying instead of making them desperately horny and willing to do anything to relieve that arousal.

That was what people thought, at least. Though the constant orgasms had already left Tom with a conditioned liking of the thing. He knew perfectly well that it wasn't healthy, but every time he anticipated the slime to start feeding from him again, he began to feel tingly, growing hard even before his passenger did anything. And then a blissful, unthinking ecstasy wrapping around him like a blanket as it finally began massaging his insides again.

Right now, though, his mind was relatively clear, despite that squirming pressure inside him. Maybe, he reasoned, it could be fooled into thinking that the toy was a new host, if he warmed it up first. There wasn't any reason that wouldn't work, right?

As if sensing that its host was planning some form of rebellion rather than dutifully creating more hosts, that wonderful rubbing began again, and Tom succumbed to it immediately, drooling as his body was rocked by orgasm after orgasm, to the point that he was late for class when it finally let up. Ugh. As long as it stays calm while I'm there...

Tom sighed. He must've been a day or two behind on studies by now, but it was a little hard to remember with what a blur of pleasure and anxiety the last hours had been. And each hour he studied, the slime was feeding on his cum, probably absorbing it directly from his balls and prostate now. Growing larger, preparing to split.

When Tom got to class, he could feel it wiggling around inside him again. Focusing on anything but that totally alien and yet pleasurable sensation was hard, and he repeatedly had to bite his lip to stop himself from moaning. Yet, he managed, if only for it to suddenly start on his way home. He barely managed to duck into the nearest public restroom before another orgasm hit.

This would be a very difficult bunch of days before he could get the slime out, in whatever way he could figure out.

After a few days of that, Tom had to call in sick. He had managed to not cum in class, but having to rush to the bathrooms and trying to keep from moaning - not to mention sitting in there for hours, sometimes, was just as bad. One of those days, he'd realized that part of the slime actually shot out of him, only to quickly slip back inside, with how powerful his orgasms were becoming. Even if he got the slime out, Tom thought, he'd be cumming like a firehose. Maybe painfully hard for any partners of his.

His idle freedom left his days blurring together in a haze of pleasure. At some point, he knew he'd ordered pizza, and received it, but he'd only had time to begin eating it before he fell into those spasms of pleasure again. And he actually ejaculated, this time, only not sperm. Instead, slime shot forth from his cock with such force that it nearly hit the ceiling before raining down on him in thick, warm ropes. He was left lying there, dumb-struck, staring at the mess, and his still-erect shaft. It seemed bigger than before, cumslit yawning just a little from the sheer mass of goo that it'd just sprayed out.

If he didn't know any better, he'd have said the parasite was shaping him to be a more desirable partner. But his head was so fuzzy that it was hard to think. What he did notice was that the slime that'd been ejaculated began to move after a few moments, slowly crawling along his body and towards his cock. It was still connected to the main mass inside him.

That couldn't be a good thing. He touched the gooey, white string that narrowed as it retreated back into his cock, in order to tear it off and toss it into the nearest sink, when another pleasurable vibration against his prostate nearly made him pass out. Ooh. No, he'd not be that easily influenced. He stood up, only to fall down onto his knees as another intense jolt shot through him. He was so hard it was physically painful, and his thoughts kept drifting to that. It didn't feel unpleasant, being still a little warm with his body heat, and tickling as it slowly snuck back into his naked cock. Wait, naked- when had he even taken off his clothes? Had he ever even put them on?

But each time he looked at the squirming, gelatinous thing in his hand, he felt an encouraging kind of thrumming warmth, like a crush that'd been forced on him by chemicals and pleasure both. A lot like the first time he'd held hands with his very first crush in middle school. Except, more intense. But that'd been real, and he knew this was just a conditioned response. Manipulation. He wasn't actually feeling affection towards the disgusting parasite, was he?

Maybe it'd be alright. He hated feeling like he was being manipulated, but it only made sense, didn't it? And if it slipped back inside him, did it really matter? He was already infested, after all. There was a kind of line he toed at, hesitating to cross it, deliberately repeating the act of letting the parasitic thing back into his body, but he needed to cum or he'd not be able to think clearly at all. And the core was already inside him, so it didn't really matter what he did.

Right? Yeah, of course that's right. Feeling it slip back inside him would probably make him cum again, anyway, and maybe it'd calm down after that. Perfect reasoning. Tom's mouth felt dry as he stared, spellbound, breathing shallowly in anticipation of more pleasure.

When it began to retreat, his world shattered into glowing fragments of pleasure. It was like he was both sinking into something very warm and wet, and in turn being penetrated himself, and he could barely catch his breath enough to moan. Like an orgasm in reverse, but not unpleasant. Rather, the opposite, the same orgasmic sensations but ones that left him feeling _full_rather than drained.

While Tom was hesitating and rationalizing it all, the last of the slime retreated back into him with a wet slurp, and soon the familiar - almost comfortable, at this point - pressure was back inside him. It left him panting, squirming, and the massaging began almost immediately after, and he couldn't help but feel like the slime was rewarding him for his obedience. But these parasites weren't supposed to do that, they were merely-

He came almost immediately as the slime reinforced his good, docile behaviour by assaulting his growing, strong prostate, and this time, the goo hit the ceiling, repeating the process.

After that orgasm ebbed, there was a sudden, intense _pressure_in his balls, pressure and what almost felt like a vibration, but was far more pleasurable. Oh, it was happening. He shivered as he felt his passenger shift, moving down in his body. It was going to infest his balls. He had no idea how it was doing it without breaking him, and each moment he was bracing himself for a jolt of pain that never came.

He groaned, an intense feeling of pressure building up around the root of his cock, slowly spreading to his sack. Once again, the stimulation had him hard as rock, with both pleasure and anticipation. And then, a sudden relief, almost a tangible pop in his scrotum. Looking down, it looked as if he had three balls in there, and for some strange reason, the sight was incredibly erotic to him. The central one - the core of the slime, having left most of the excess elsewhere in his body, was squirming, apparently seeking to split into two.

Tom felt a strange pride, a pleasant fuzziness that enveloped his whole body, at what a good incubator he was being. It wasn't a real_emotion, but it _felt real. Like he was helping his wonderful companion, and it was making him feel so very good in return. His sack felt heavy and the way the slime squirmed against his real balls was strangely pleasant. It had completely enveloped them in its body, ensuring that it'd not miss a single drop of his seed.

The next day, he realized that his balls felt heavier. Looking at them, he could see why; they were quite a big bigger than yesterday, leaving a very obvious, suggestive bulge in his boxers. They felt almost gelatinous to the touch, except for the three orbs contained inside. It almost seemed as if the slime was stimulating actual growth rather than just filling his sack entirely, as his balls seemed larger too.

How much larger would they get, he wondered. Somehow, it was a bit of an ego boost, being so well-hung all of a sudden, even if it was because of a parasitic slime.

With each passing day, though, they grew bigger, from slightly above his previous size to a fist-sized pouch, and further from there, which left Tom wearing very, very loose pants each time he had to go anywhere. It got the to the point of being so obscenely large that it stopped being sexy, but Tom himself was so inundated by his passenger's clever chemical manipulation that to him, each further swell was like a mark of pride. Well, as long as he could hide it.

Eventually point, he struggled to even sit down with how well-endowed he was becoming. The slime was definitely growing, and as best as he could tell, between how it felt and what he found on the internet, it was preparing to split.

He had all but stopped thinking of having the slime removed at all. He couldn't, with the constant orgasms. Maybe once it'd successfully split the first time, he'd told himself. But time passed quickly, what with them being a hazy blur of lust and pleasure, and soon, it was time. The pressure had grown so much that his balls were stretched taut, and there was an odd nudging in there, a vibration. An overwhelming urge to find a partner to stick his cock into, which he luckily couldn't.

Still, Tom managed to at least prepare the jar and the toy. No doubt at least one of the slimes would want to leave his body the moment it was done dividing. The core in his sack continued trembling, almost shivering, as it slowly divided into two, and with each passing moment it fed more electrifying lust into Tom's body. He felt incredibly full, and in a weird way, content, to feel it reproduce using his cum, but above all that was the empty-minded shivering ecstasy. God, he hoped it'd be done soon. He needed to cum. Needed to-

The moment the slime separated into two cores, he jammed the toy down on his cock, humping into it with feverish need. His entire body felt as if it was coiling up, preparing for a release beyond his wildest dreams. It only took a few moments, the slime registering only the pressure around its host's cock, and assuming that he'd found a mate.

Tom came. And he came so hard that he lost all coherent thought, whimpering uncontrollably as he ground against the toy, feeling it nearly slip out of his hands from the sheer pressure his cum shot out at. The new core pushing through his urethra was indescribable, like a bulge of searing hot pleasure that threatened to make him pass out entirely. It didn't come in one spurt, either; rather, each contraction of his muscles shoved it a little further forward. It wasn't quite as big as the original, safely lodged inside his sack, but it was still far bigger than anything his cock was meant to let through. He looked, briefly, through eyes tearing up with pleasure, and saw that obscenely large bulge enter the very base of his shaft.

Tom closed his eyes. He was afraid he might tear, on some level. But he didn't, the slime wouldn't allow him to get hurt. After several more heaving breaths and a perpetual orgasm so hard he struggle to even breathe, he screamed with ecstasy as it finally popped through his glans and into the toy with a heavy clunk. And then, even in the throes of that incredibly orgasm, he managed to just barely wrench the toy off his shaft and close it before collapsing into a heaving pile, muscles tensing and relaxing in rhythmic contractions as he ejaculated even more slime.

His energy finally ran out and he fell asleep in a mixture of slime and, for the first time in several days, actual cum that kept drooling from his shaft in the aftermath of his climax. The slime probably simply couldn't feed any more at that very moment.

When he had recovered, he shipped it off to the toy company. The money he got from what should be enough for some emergency surgery to get the original out, but he hesitated. It had been a wonderful experience... or at least, that's how it felt in retrospect. Rose-tinted glasses and all. There was that warm, spine-tingling sensation every time he looked at his sack and thought about the slime in there, recovering from splitting and soon about to begin feeding again. How full he felt, the satisfaction - it was rather addictive, in the weirdest of ways.

His studies seemed less important. Instead, Tom found himself wondering if there was a way he could help the slime, maybe by being host to more than just one. It was all terribly foolish and he knew that. And yet...

There had been some runes on the toy, which he still had. Even though they were cracked, they were still visible. He spent some time he should've spent on studies on researching them instead, driven by sheer _lust._Several of them had particular functions. The ones on the toy allowed the slime to fit into far less space than it'd normally take, improved the durability of it (though not enough to save the runes themselves from cracking if dropped, it seemed) and finally, one that allowed the slime to subsist without nutrition for far longer than it normally could.

He looked at his balls. The sack almost seemed deflated, now. But if he had the capacity to host two of them comfortably, he could both feel twice as good and make twice as much money, right?

Really, it was an excuse. Tom's fingers trembled as he looked up the other simple runes, feeling that happy buzz envelop his body as he learned each one, the slime rewarding him for his help. It had to be sapient. To some degree, at least. Or maybe it had absorbed part of Tom's brains along with his cum, he didn't know. It was very pleased that its host was trying to figure out a way to be an even better incubator, though, and that heated thrumming intensified as he continued that newfound avenue of studies. These ones seemed important.

Only briefly, did Tom hesitate, before finding a sharpie and drawing the one that meant capacity on his balls. Nothing felt different, but the slime stirred. He'd probably have to wait to see if the next core ever got ejected. At least he'd tried. And his passenger, as usual, rewarded him by completely erasing all attempts at rational thought when it suddenly began massaging again, sending Tom into writhing paroxysms, each one ejaculating a good bunch of the slime, only for it to retreat back into him, in wonderful rhythm.

He was happy.

A few weeks later, he was even happier. Tom sighed contentedly, sprawling limply on his bed and caressing his overfull sack. The rune had worked, and even better than he'd imagined. He couldn't wait to feel his wonderful slimes reproduce again. He'd have a total of four, and at that point he'd be swollen he'd barely be able to walk at all, much less go outside. Or if he found a friend to share this pleasure with, he'd do that, too. Gods, he was happy. Content. Nothing else mattered but that glowing full-body relaxation, and the next, bubbling orgasm that was already building up in his loins.

Being a slime incubator wasn't so bad.
