People were bursting out of their rooms, writhing, screaming, and desperately swatting at their bodies. Alien spiders of all difference sizes were crawling on them.

Breasts were out and openly bobbing, some of the mounds in the process of tearing free of the pajamas that contained them. They were all round and full, wiggling, throbbing. Some sprayed spurts of milk, and yet others had tiny spiders forcing their way in or out.

“Oh gods,” Eric moaned. He had to get back to the lab. He crawled along the corridor, people screaming, writhing, and collapsing all around him. One man tripped over Eric’s form, but Eric didn’t stop. He kept crawling forward.

Then Cona came out of her quarters. She was completely covered in spiders. She staggered forward, but then froze, and clutched her swollen abdomen as it heaved and sweated against the nightgown she was wearing.

Then something fell from between her thighs and smacked hard against the floor. It was an…egg. A large one, the size of the tennis ball. Cona groaned, shivered, then egg after egg fell from between her thighs, plopping down onto the floor. She released a disgusted squeal, clutching at her stomach.

A man keeled over, and the seat of his pants began to tent out in a grotesque sight, something wiggling and straining to break through the material.

Some of the spiders creatures appeared to be cannibalistic, eating each other, and growing rapidly in consequence.

Eric felt like he was going to be sick. In fact, he felt like he might just start purging from all orifices. He managed to get to his feet and tried to hurry away, but his dick was stirring, stretching, and contorting in such a grotesque way that he started to scream. And then, before he could even deliberate how to stop it, the creatures sprung free, fat grubs spurting out of his straining cock as he reddened and whined, and his creatures splattered into the already ensuing chaos.

The worms themselves were highly active. The moment they were born from Eric’s cock, they began to wriggle madly, and hurry towards the orifices of others, as though magnetized. They stuffed themselves into people’s mouths, noses, vaginas, and assholes, joining the spiders in the parasitic madness.

It was all too much for Eric. He collapsed to the ground unconscious, his round belly throbbing, and dick continuing to twitch and swell. A slug crawled onto his chest and began to prod at his nipple.

-

John, Simon, and Mike had barricaded themselves in the lab.

“This is madness,” said Mike, who was shuffling from one device to the next, tinkering with it in his anxiety. “What we’re dealing with is a parasitic epidemic. Soon we’ll all be infected! And we still have no clue how to eliminate these things!”

Simon looked like he might dart off at any moment, but John was characteristically calm.

“Our best chance of survival may be to abandon the ship,” said John. “Though in that event, I’m doubtful our overseers would let us live. Our internal trackers wouldn’t allow us to evade them for long.”

“That isn’t an option,” said Simon. “We have to figure out how to kill the creatures. Though I’m not sure we can get close enough to run more tests. Now without an extreme risk of infection.”

“There is one sample that has been consistently calm,” said John. He motioned to the massive egg that Sarah had left with them. “Shall we get started?”

-

They attempted treating the egg with heavy doses of the most lethal poison onboard, then gave it enough radiation to kill several Martian elephants. Mike tried stabbing it, but the surgical blade simply ricocheted off the shell. Finally, they dumped the egg into a large tub of extremely corrosive acid, and to their amazement and relief, the shell showed signs that it was degrading.

The screams were getting closer, some even heard just outside of the lab. Undoubtedly, the epidemic was spreading. The three scientists tried to stay focused on their work.

There was a beeping noise, signaling that someone had gotten through the first layer of security on the lab. John hurried to the security console and quickly lifted the secondary shields, just before a figure could burst into the room.

She crashed hard against the glass wall that had lifted as a barricade just in time. She pressed herself against it, looking dazed and nauseous. She had dark blue hair, sea green eyes, and was vaguely familiar, possibly one of the service staff members onboard.

Her previously pale skin was flushed with heat and strain. Though small-framed, the woman’s breasts had grown to be enormous, and had recently burst free of her jumpsuit, sticking out, bobbing freely, bobbing…almost, on their own. Moving, shifting. Each breast was the size of a basketball, nipples like shot classes, and animatedly wiggling, as they simultaneously spurted thick milk into the glass. Something began to…crown, out of one, and a strange, squirming mass began to emerge, but only partly, from her nipple.

It was a sickening sight. The girl was moaning and pawing feebly at the glass. She began to sink, her breasts rubbing and leaving milk streaks everywhere. The worm creature began to sink back into her nipple. As the girl collapsed to the ground, the scientists only then took notice of the other form trying to make its way to the lab.

It was Eric, but a decidedly…different version of him. He was sprawled on the ground, panting heavily. He looked as though he had tried to wrestle his way out of his clothes, and had given up halfway there.

He attempted to crawl again. His belly was so large, it was rubbing on the floor, flushed red, and evidently straining the tight skin that covered it. Eric was soaked in sweat, panting, wheezing. He had developed small breasts on his chest, and like the girls’, they were leaking. To a less severe degree, but they were dripping milk.

There were…slug things. Fat ones, with pallid, twisting, bodies. Some were crawling on Eric. The man groaned and fell again, this time lying on his side, twitching. The other scientists watched as some of the slugs crawled up to Eric’s chest and began to attach themselves to his nipples as though—as though they were nursing!

Eric spread his thighs. His dick was enormous, and red, and twisting! It contorted in a horrifically painful image that made even John grimace, as it bulged at the side, bending, and warping. Finally Eric released a cry, and arched, as a slug burst out of the head of his deformed penis. He whimpered, and clutched his gender, rubbing it and contracting as slug after slug burst out of its strained opening.

Eric again tried to get up. “H…help,” he grunted. He trembled on all fours, his belly pressing into the floor.

He made to crawl, but instead vomited a beige liquid that was grainy. In fact, things seemed to be wriggling in it as it rolled down his chest. His breasts seemed to swell, Eric moaning and shaking. He began to rock himself so that his cock prodded against the underside of the huge mass of his belly.

There was a splashing noise behind the scientists, followed by the hiss of erosion. They spun to see that a giant, fat, alien spider had been born from the giant egg, acid rolling off it like water, to erode the metallic floor. John quickly opened the glass wall. He, Mike, and Simon attempted to back away from the prowling spider monster, but it leapt at them, and everything else was a blur.

-

Eric was curled on the floor as his belly heaved, viciously jerking himself off. “Oh god…” he groaned as he released spurt after spurt of slugs that squirmed on the floor, or came back to nurse from him or invade his other orifices. His belly continued to swell in the meantime.

Not far from him, the blue-haired girl was sprawled on her front, on the beachball-sized pillows that her breasts that become. They continued to steadily rise like dough, as a pool of milk formed beneath her, and she made muffled moans of arousal.

Worms and spiders were completely covering Simon’s body as he squirmed and whined pathetically, sometimes choking on a particularly thick one.

Mike was releasing shrill screams as the giant spider progressively swallowed him, from the feet down. It was sucking Mike in rapidly, and he could do little more that writhe and feebly paw at the hungry creature.

A large slug had appeared, not as large as the giant spider, but still as daunting four-feet long, and almost half its height in thickness. It cornered a quavering John, then pinned him down. But rather than eating the man, it began to stuff itself into John’s mouth, John releasing choked grunts as his mouth was forced wide open, and his throat bulged. The slug contorted, compressed, and shoved onwards, John thrashing there on the floor as his stomach began to balloon outward.

Eric just sobbed and continued to jerk off.

-

Sana was surprised to find that she was immune to the creatures. For some reason, they didn’t see her as a host anymore. Perhaps because she had successfully purged one from her body. She didn’t know, but she was grateful.

“I am giving you full authority to take over the situation,” her overseers responded on the radio. “Save the vessel. Do not let it spread off that ship. Do whatever is necessary.”

“I understand,” Sana responded neutrally, before turning off the radio. She walked along the corridors, looking at all the sweating, heaving bodies sprawled about. Several of the creatures were growing large in size. They would continue to try to inhabit alien hosts even despite the fact that they seemed to survive quite well without them.

Sana stopped at the sight of a particular figure curled in a corner. She leaned down and turned the person over, giving a quick visual examination.

Cona was packed with eggs, still actively birthing them even in her unconsciousness. Her belly was massive, breasts swollen fat again, while periodically releasing tiny eggs from her straining nipples, while her groin consistently pushed out very large ones, that seemed to be progressively growing, judging by the various eggs already scattered around her form.

Sana thought of the drug she had used, and its handiness in this matter. Cona wasn’t going to enjoy the decontamination process. With great struggle, Sana heaved Cona up and began to drag her off.

The End
