“Do you ever think about getting pregnant?” Sarah asked as she dried her hands under the bathroom’s air dryer.
Katherine furrowed her brow. They’d been friends forever, and she’d never said anything like that before. “Like having kids, or actually being pregnant?”
“I mean being pregnant. Having another living thing growing inside of you.”
Katherine stuck out her tongue. “I’m never going to get knocked up. Giant belly, sore breasts. lactating? No thanks. I’m happy just the way I am. Besides, once you have kids, they’re your whole life. I want to accomplish things.”
Sarah giggled. “I was right there with you for the longest time, but then you meet that special someone. . .” she trailed off, gazing upwards with a smile.
Katherine stifled a groan. Sarah was talking about Tim again. That was all she ever talked about these days. Wasn’t it enough that they spent every waking minute wrapped in each other’s arms? As soon as they got back to their table, Sarah would be all over Tim again, holding hands and kissing obnoxiously between bites.
“That’s just your supercharged hormones talking again,” Katherine joked.
Sarah rolled her eyes, “You’re probably right.”
It made sense to Katherine that Sarah would be the first to go baby crazy. Ever since puberty, she’d been a little jealous of Sarah’s hormones. It had been difficult to watch her best friend transform into a well-endowed beauty while she was left with a slight, girlish figure. Still, she didn’t envy the strange urges the hormones seemed to bring.
“Try to hold off on the kids until your first anniversary,” Katherine teased as they stepped back into the restaurant. It was easy enough to spot their table. It was the one Nate, her giant beefcake of a date, was looming over.
Nate hated this restaurant's stupid fancy chairs; he barely fit in them. He looked around for Sarah and Katherine. The sooner they got back from the bathroom, the sooner he could leave this terrible double date.
His best friend Tim smirked at him from across the table. “You’re not doing so hot with Katherine tonight, are ya?”
Nate put on a fake smile. He was beginning to think Tim had set up this stupid date just to show off how utterly infatuated he and Sarah were.
“Don’t worry, I’m working my magic,” Nate lied. “She’ll be all over me by the time we’re done stargazing.”
Tim grinned. “Is that so? I’ll bet you $20 you don’t get laid tonight.”
“Yeah right,” Nate scoffed. He had a thing for petite women like Katherine, but she seemed like an emotionless robot, full on. No way he’d get into her pants tonight. They’d hardly said a word to each other all dinner. The only thing they had in common was that their best friends were fucking.
When the women returned, Sarah ignored her chair and sat right on Tim’s lap. Mercifully, Nate didn’t have to wait long for the check. He quibbled with Tim over who had the privilege of paying, but quickly gave up. Tim seemed ready to turn it into one of their famous week-long competitions, but Nate just wanted the nightmarish dinner to be over.
The group piled into Sarah’s SUV and started on their way to their town’s most popular stargazing spot. Nate was staring out the window trying not to get carsick when he saw a shooting star bright enough to light up the sky. He wished he was home watching sports, or at the gym working out, or anywhere other than this car.
“You really can see a lot of stars from here,” he observed.
Katherine nodded in agreement. “Yeah. Look at that big pink one!”
“Where?” asked Sarah. “Oh I see it! Wow it’s huge. Maybe it’s a comet or a meteor or something.”
“It’s getting bigger,” Tim muttered, and indeed it was. Soon it was larger than any other star, then half the size of the moon, then larger still. Nate was getting nervous.
Katherine sat upright with fear and cried, “it’s not getting bigger. It’s coming straight at us!”
The meteor hurdled toward them, and soon the pink light filled the night sky and flooded the car, casting stark shadows throughout the interior. Nate clenched his eyes anticipating the collision, but it never came. The source of the light, now far too bright to look at, hovered above them.
There was a jolt, and the SUV’s engine revved as its tires lifted off the ground. Everyone but Katherine screamed and panicked as an unseen force pulled the two ton car up into the air.
“It’s a UFO!” Tim shouted.
Nate wanted to argue with him, but considering that their car was flying straight up toward the unnatural light, he thought better of it. Before he could come up with a more reasonable explanation, a wave of dizziness overcame him and he lost consciousness.
.-=o=-.
When Nate opened his eyes, he found himself somewhere that didn’t seem like the inside of a spaceship. Everything was made of wood. Light streamed in through knotholes in the ceiling, and the walls creaked in the wind. It was a barn. His clothes had disappeared, and he was laying on a pile of hay that poked and scraped his bare skin. Sitting up, he found the rest of the group holding their heads and moaning as they came to. They struggled to conceal their nakedness, clasping their hands over their privates. They were in a stall.
“Did we crash?” He asked, pushing himself to his feet with one hand while the other protected his modesty.
“We couldn’t have,” answered Katherine. “No one has a scratch on them.”
Nate inspected the others, initially to confirm that no one was injured, but then out of curiosity. He couldn’t resist stealing a glance or two at the pair of blushing women standing nearby.
Katherine had no trouble covering her small, perky breasts with one arm, but Sarah had more difficulty staying modest. She was taller, more voluptuous, and her breasts were massive. Even with both her arms crossed in front of them, there was plenty to ogle. She crossed her legs, but it did little to hide the patch of well-maintained pubic hair between her legs, or her wide child-bearing hips. She was a full-on babe. He wondered what a hottie like her saw in scrawny-ass Tim.
Tim averted his eyes from the women in an attempt to be polite and ended up looking at Nate. But when he saw what was between his best friend’s legs, his idle glance turned into a stare. Tim knew Nate was stronger and taller than him, but, as it turned out, he also had a much bigger dick. It was so large Nate was having trouble keeping it covered, even using both of his hands. It was an honest-to-goodness pornstar penis, hefty and plump but long enough to hang down past his sizable balls. Even though Tim was as straight as an arrow, he couldn’t help but gawk. He knew he was just average. Average height, average weight, average dick. He felt inadequate, especially when he noticed Sarah also stealing a glimpse at his friend’s crotch. He needed to say something.
“I think we were abducted by aliens.”
Nate nodded. “They must have wiped our memories and dropped us off in this stable.”
“What did they do with our stuff?” worried Sarah.
As the questions multiplied, Tim’s heartbeat quickened. How could this situation get any worse? He waddled to the gate, but the latch was stuck. He moved to climb over it, but when he tried to reach past the gate, he hit an invisible wall. It didn’t make sense. There was no barrier that he could see, but he couldn’t move past it. He turned back to the group.
“Guys, we’re trapped. And this isn’t a stable.”
Suddenly, a loud hiss filled the air. Tim would have jumped, but he found himself frozen in place. Try as he might, he couldn’t move a muscle. His friends were frozen as well, their panicked eyes staring out of fixed expressions on their faces.
Then the stable itself flickered, warped, and faded away into an empty, cube-shaped room. The entire place, walls, floor, and ceiling, was covered in a grid of flawless white tiles. A section of the wall opened up with a sharp swoosh. Two creatures entered the room, and Tim’s stomach flopped. They were aliens.
At first glance they looked like giant lizards with six legs. They had long bodies, sported thick tails, and their heads had wide, reptilian muzzles. That is where the resemblance to Earth creatures ended. Their legs were longer and less splayed out than a lizard’s, giving them more of a dragon-like posture. Their smooth pebble scales were a sort of grey-green color, but the larger one was a shade darker. They scurried up to the humans on all six legs but shifted into a four-legged stance as they started examining their catch.
Tim screamed internally as they approached him first. The larger alien used its cold, scaly hands to reposition his body into a standing position with a wide stance, pulling his arms away from his privates in the process. Then each alien produced an instrument that looked like a stainless steel chopstick and promptly started using them to poke and prod his helpless body. The larger one lifted up his lips to look at his teeth, then inserted one as far as it would go into his belly button, then into his ears and up his nose. They chittered and hissed at each other as they worked.
Tim’s eyes bulged with terror as he got his first up-close look at real, live aliens. They were huge, standing a solid eight feet tall with four of their legs planted on the ground. Each alien stared down at him with two pairs of glassy black eyes. Their muzzles had four nostril slits and long fleshy tendrils sprouting from their upper lips. Their faces were expressive and intelligent.
Sarah, positioned on the opposite side of the room, was treated to an excellent view of the aliens’ backsides. Their tails were long and fat like a lizard’s, but rounder and more flexible. Their twin tips waggled in front of her face, and were anything but ordinary. Instead of ending in a featureless point, the scaly skin gave way to a smooth, fleshy tip with a slit-like opening at the end. It looked to Sarah like a dick, but without a mushroom head. The scaly skin of their tails was like a foreskin that partially covered the sensitive-looking organs. One of them brushed against her cheek, leaving behind a smear of viscous fluid that smelled like turpentine.
The alien’s chittering turned more enthusiastic as they examined Tim’s genitals. They used one rod to lift up his limp penis and caressed his testicles with the other. The instruments began to thrum and vibrate, and Tim’s dick swelled. He wasn’t horny in the slightest, but soon his penis was standing up, fully, achingly erect. The aliens looked at each other, made a sound that could only have been a laugh, then moved on to the next captive.
They examined each of the other humans. Nate was also given an erection when it was his turn, his monstrous cock standing proudly in the air for everyone to stare at. The women weren’t spared an embarrassing examination when their turn came. The aliens used their probes to part their vulvas and test their depth. Sarah blushed furiously as they violated her in front of her friends. She closed her eyes, as if that helped.
Once everyone had been examined, the larger, darker alien moved out of view and returned holding a strange creature. It looked like a bright pink jellyfish that had been stretched from a perfect circle into an oval. A multitude of short, thin, tentacles that swayed and undulated beneath it. The alien brought this creature over to Tim and placed it gently onto his forehead, lying it lengthwise so that it sat like a floppy pink mohawk.
Sarah watched as the jellyfish quickly lifted its tentacles and pushed them into her boyfriend’s scalp. Tim’s eyes once again filled with terror and then, a moment later, relaxed. If the intrusion hurt, his half-lidded eyes gave no sign of it. Katherine was next to have a jellyfish placed on her head, then Nate. Both reacted the same way that Tim had. Finally, one was brought to Sarah. Her eyes watered with fear as she felt the cold, gelatinous creature paced against her skin. A very curious and disturbing chill ran down her spine, and suddenly, she too relaxed. It no longer worried her that they were being held captive by aliens that were planning to do who-knows-what with them. She felt the tentacles pushing into her skin and down through her skull, but there was no pain, only calmness.
The aliens turned away from the humans and started having what appeared to be a very heated conversation, spitting and hissing and chirping and chattering. Their indecipherable quarreling rang in her ears as the jellyfish caressed her brain.
Sarah’s state of artificial serenity lasted about a minute. As she came to, the aliens were still bickering about who was going to take the blame for this colossal mistake. Wait, that wasn’t right. She shouldn’t know what they were arguing about. The noises they were making still sounded the same, but she found that the longer she listened, the more she understood.
“My decision is final!” hissed the larger, darker one. “I will ask The First to show mercy on you.”
“Hisssss. . . Yes, doctor Sslsskss.” The smaller one replied. “Here he comes!”
The door opened once again and another alien entered the room. This one’s skin was a deep charcoal grey, almost black, and while the other aliens were nude, he wore a blue band of fabric around his upper torso.
“Chief veterinarian Sslsskss,” he rumbled, menacingly. “Please explain what these are.” He nodded his head toward the humans.
“Ah yes, He-Who-Is-Greater-Than-I. These are the new livestock, four examples of the dominant species of Stellar Object 190294, as promised.”
The leader lumbered over to the humans and squinted his four eyes. “I was told that they would look more like this.” A hologram flickered to life in the middle of the room. It was a perfect depiction of a chestnut stallion. “Has there been a mistake?”
Doctor Sslsskss swallowed nervously. “Ah yes. Perhaps, a small one. It seems that my apprentice, Klkss here, mistook a domesticated species to be the dominant one. These creatures, stupid and primitive as they are, are the only creatures on the planet that are intelligent enough to suit our needs.”
There was a pregnant pause while the leader considered the situation. “Doctor, how long will it take to synthesize a serum for this species’ genetic pattern?”
“At least a week. Perhaps longer.”
“I cannot wait that long. We are in desperate need of bioslugs. You know that more than anyone.” They all hissed to themselves for a while. “Would it be possible to use the serum you prepared for the other species on this one?”
The doctor glanced at Sarah with a look that turned her stomach. “Hisssss. . . Perhaps. I can make no guarantees. The effects on their bodies and minds would be unpredictable. They could end up as nothing more than a pile of genitals, or it might drive them mad. It could even kill them.”
“A small chance is better than no chance, doctor. Select the most virile pair and administer the serum you made for the. . .”
“It is called a horse, He-Who-Is-Far-Greater-Than-I” churred Klkss the apprentice.
“Administer the serum you prepared for the horses to the breeding pair, and begin work on a serum tailored to this species immediately.”
“Yes, yes. Immediately, He-Who-Is-Merciful.”
With that, The First turned and left. The humans looked around frantically, the artificial calmness of the jellyfish having given way to sheer panic as they wondered which of them would be the first to be subjected to what they now realized was a dangerous, alien experiment.
The apprentice relaxed visibly. “Whew! That was close. I thought for sure The First was going to recycle me.”
“Another mistake like that and I’ll recycle you myself!” snapped the doctor. “I am thirty-third and you’re 402nd, it would be well within my rights. Now, fetch me two bioslugs, and be careful! We only have five left.”
Klkss gulped and scurried away.
The veterinarian turned to the humans and, for the first time, spoke to them directly. “Hisss. . . Close your eyes if you can understand me.” Everyone’s eyes shut. None of them decided to close them. They just moved on their own, like a reflex. “Good. Now open them.” Their eyes opened.
“Excellent. It appears that the t’tssk have fully integrated themselves into your rudimentary, centralized nervous system. When I release the forcefields you will not move from your locations or take any violent actions.”
A small semi-transparent holographic control panel appeared in front of Sslsskss’s hand. He twitched his finger, and Sarah found herself able to move again.
She immediately started screaming.
“Gah! Hissss. You will not make loud noises!” He frantically chittered, covering his ear holes. Sarah stopped screaming, but continued vocalizing at a more reasonable volume, mostly babbling incoherently in terror. She wanted more than anything to scream and run, but her body wouldn’t let her. She wiggled her fingers and said her name just to prove to herself that she still had some control over her body.
The alien flicked his wrist, and Nate, Tim, and Katherine were freed from the forcefield. The men groaned and moaned nervously, but Katherine was silent.
Katherine reached up and touched the t’tssk on the top of her head. It was cold and slick. To her horror, she found that she could feel the touch of her fingers against it. It made sense if the creature had truly interfaced with her brain. She traced her fingers around the edge but couldn’t find a clear place where the creature ended and her forehead began. Incredible. She wanted to keep prodding it, but it was too sensitive.
“What did you do to us?” Nate asked as the rest of the group inspected their new pink crests with looks of horror on their faces.
Just then Klkss returned, a large egg-shaped container hovering behind him.
“Ah, there you are. Excellent. How should we designate this livestock? You are the expert on the relevant planet.”
Klkss pointed to Sarah and Katherine. “Yes, um. These two are called ‘mares’, and these two--” he pointed to Tim and Nate, “are ‘stallions.’”
“We have names. I’m Katherine.”
The others began to timidly introduce themselves as well, but the doctor interrupted them. “You will all ceace communicating.” They fell silent.
Klkss pursed his claws nervously. “Now that The First is gone, just what are the odds that this will work?”
“These animals share 87 percent of their DNA with the creatures we prepared the serum for.”
The apprentice’s face lit up, “So 87 percent chance of success?”
“No, you idiot!” snapped Sslsskss. “It doesn’t work like that. I suspect their reproductive systems will be properly altered, beyond that I can only guess. Now, give me your probe.”
He snatched Klkss’s probe away and opened up a holo-panel in front of himself, tapping away as he continued speaking. “Let’s begin. You, stallion, and you, mare,” He pointed to Nate and Sarah, “come here.”
The pair approached the alien, sweating and shivering with fear. Sarah stared back at Tim as she took her compelled steps.
“That’s close enough. Now turn around, get down on four legs like a civilized creature, and present your rears.”
The couple got down on their knees and leaned forward, raising their bare asses into the air. As they assumed the exposed, vulnerable position, Sarah blushed furiously, and Nate frowned and tried not to make eye contact with anyone.
Klkss reeled back and stuck out his bright green tongue. “Eck! These are the orifices they use to expel waste! Disgusting!”
“Hisss. . . indeed, but they are filled with sensitive membranes and an ideal location to administer the serum and bioslugs.” The doctor’s holo panel disappeared, and the metallic instruments in his hand began to warp and change shape. “You, smaller stallion, come here.”
Tim panicked. Had his body been under his command, he would have run away. Instead, he steadily advanced until he stood between the naked asses of his lover and best friend. The alien presented the two reshaped probes to him. They had a narrow tip, a large bulge in the middle, and a flared base. In fact, they looked exactly like small, stainless steel butt-plugs.
“Take these probes and insert them into the excrement-holes of the other two.”
Tim’s hand reached up and took the probes from doctor. He desperately tried to stop himself, but no matter how much he resisted, his body moved with a will of its own. There was a fleeting flicker of freedom as he chose which of his friends would be first. He turned to Nate and kneeled behind him, his face closer to his best friend’s hairy, well-toned ass than he ever wanted.
“Don’t do this, Tim.” Nate pleaded, clenching his asshole. “Please! Listen, I’m sorry I told people about your browsing history. You don’t have to do this!”
Tim frowned and touched the tip of the rod against Nate’s opening.
“I’m. . . I’m sorry.”
With that, he pressed the probe inward. Nate’s asshole strained against the invader, but it was no use. Tim cringed as the probe pressed inside, until the widest part of the probe disappeared into his friend’s body. Nate clenched his ass around the far side of the bulge, inadvertently pulling the plug out of Tim’s fingers as it sank in to its flared base. Once inside, the probe began to thrum and vibrate. Tim could see it expanding, stretching Nate’s opening wider than it had ever been stretched before. Nate groaned and pushed, but the metal plug had grown too large to force out.
“I’ve modified the probes with a custom program,” Sslsskss explained to his apprentice. “They will clean the waste from their bowels, administer the serum, and prepare them for the bioslugs.”
Nate breathed heavily, making little vocalizations as he exhaled. “It feels. . . So weird. . . So big! Tim, help. Please.”
Tim wanted to help, but even if he wasn’t being puppeted by the jellyfish on his head, he wouldn’t know where to begin. The probe had nearly doubled in size, and it only barely fit to begin with.
Doctor Sslsskss let out a slow appreciative trill, and for a fleeting moment Tim felt somehow relieved that the doctor approved of his actions. “Good. You will insert the other probe into the mare now.” The doctor turned to Klkss. “It is important to be very clear in your instructions. The integration of a t’tssk always carries some cost to the subject’s intelligence.”
Tim’s anxiety returned as his body repositioned itself behind Sarah’s plump bottom. He didn’t feel any stupider, but he started to worry. Maybe the jellyfish on his head had diminished his intelligence, and he would normally have no trouble finding a way out of this situation. He gazed at his lover’s familiar, shapely ass, tears forming in his eyes.
“Oh God, Sarah. I can’t stop myself. I’m so sorry.”
“I know, Timmy, I know. Just, please, be gentle.”
Thinking quickly, Tim spat onto his fingers and rubbed them on her flawless, pucker. He raised the probe to her asshole and applied steady pressure until the tip slipped inside. She was much tighter than Nate, but his saliva was an effective lubricant. The probe slid in easily. He had always wanted to try anal play with Sarah, but not like this. He placed a calming hand on her hip as he continued.
“Ow!” Sarah yelped. “Slow down!”
He was already pushing as gently as he could. “Try to relax, love. It will be easier.”
Sarah’s asshole loosened momentarily as she tried to comply, but when the insertion accelerated, she clenched reflexively. Then, just as it had for Nate, the probe’s bulge passed through her straining hole, and the plug thudded into place. Sarah moaned with relief as it lodged itself inside her innards, and Tim, who was mortified at what he’d done, leaned forward and kissed his girlfriend’s butt cheek in apology.
Next to them, Nate was groaning loudly. “It’s too big!” The plug was stretching his hole to its limit, and at the same time vibrating against his prostate so intensely that a string of precum was hanging from his dick. Soon Sarah’s voice joined in, moaning in discomfort as the probe expanded inside of her.
“Excellent.” hissed the doctor. “Watch closely, Klkss, there is much to learn.”
The apprentice was leered at the scene out of the corner of his eye. “Blech! I find their primitive digestive systems disgusting. The very thought of producing and excreting waste makes me want to stick my tongue down my own throat.”
Sslsskss chuckled. “It won’t be long before our modifications cleanse them. Soon their metabolic systems will produce only useful, non-toxic byproducts. Well, if they survive.”
Katherine closed her eyes and covered her ears to shut out the horrors around her, but Tim couldn’t help but watch. Sarah and Nate were lost to the world as they endured the overwhelming sensations coming from their asses. Then, a few agonizing minutes later, the probes stopped vibrating and began to shrink.
“Finally. The probes have finished their preparations. You, smaller mare, go reach into the incubator over there and fetch me two bioslugs. Be careful, they are very valuable.”
Katherine’s body moved of its own accord to the egg-shaped incubator. It was smooth and shiny like polished glass. There was a sphincter-like opening on the fat end, and the moment she was close enough, her hand shot out and pressed inside. She sneered in disgust as the slimy opening swallowed her arm. The bottom of the container was alive with slick, wriggling creatures. She grabbed one and pulled it out. The bioslug wrapped around her hand like a constrictor. She stared down at the creature with fascination and fear. It was as long as her forearm and twice as thick. Its malleable body was semi-translucent with electric blue highlights, and its head was adorned with a crown of three meaty stalks that waved about in the air like antennae. She reached in with her other hand, grabbed another, and brought them to the alien veterinarian.
Doctor Sslsskss stroked Katherine’s new crest when she arrived, and it felt marvelous. The probes in her friends’ asses had shrunk back to their original size. Their assholes, now thoroughly stretched and drugged, gaped open around the devices, twitching in a vain attempt to clench shut. The probes slid out of their oversized holes and clattered to the ground, now restored to their original chopstick shape.
“Mare, place the slugs on their behinds then step away.”
Katherine coaxed a slug off of her hand and onto Sarah’s lower back. She gasped as its hot, slimy body made contact with her skin. The slug had a very particular way of moving. It would twitch its head left, then right, and finally stretch its body in its chosen direction and pull its rear up behind it. Katherine watched it quickly hone in on Sarah’s gaping, twitching asshole. It paused a moment at her opening, stroked the sensitive flesh with its head stalks as if trying to discern whether or not this was truly the anus it wanted to crawl into, and finally pushed its fat head inside.
“No! Stop it! Get it out of me!” Sarah wailed. The slug’s body was more pliant than the probe, but it was much larger. The creature came alive with a flurry as it squirmed its way inside her swollen colon. Katherine watched as inch after inch of the slimy slug disappeared inside her best friend and estimated that it was already wriggling up into her intestines, far past the abdominal muscles that would have had a chance of pushing it out.
“It’s so deep! Pull it out before it’s too late!”
Katherine heard her pleas, but she had already moved behind Nate and placed the other slug right on his ass crack. His slug wasted no time locating and entering his abused rectum. Nate yelped, the back half of the slug’s body flopping around behind him like a perverse tail.
Klkss scrutinized the wriggling slugs. “What would happen if we introduced the bioslug without the serum?”
Sslsskss had reopened his holo panel and answered without looking up. “The bioslugs would replace the subjects’ reproductive system, but without the blueprint of the serum to guide them, they would continue to convert their organs into reproductive tissue without end. Eventually the host loses its motility. . . ”
While the doctor was lecturing, a glint from the probe on the ground beneath Nate caught Katherine’s eye. She carefully reached out with her still-slimy hand and touched it. Then Nate grunted loudly, and she jumped.
Nate’s erection had diminished after the probe had been removed, but now it was back with a vengeance. The slug tickled the inside of his rectum as its rear slapped against his thighs. The deeper it crawled, the more it stimulated his swollen prostate. He tried to squeeze his ass shut and stop the slug’s progress, but all it did was cause his hefty dick to slap against his abs. The slug writhed and wriggled as it filled his colon, bringing waves of unwanted pleasure. He wanted to hate the invasion of his body, but he couldn’t stop the sensations flooding through him any more than he could stand up and pull the slimy creature out of his ass.
The slug flexed, and another segment of its ribbed body popped inside of him. He moaned again, this time less of an agonized wail and more an unbidden expression of pleasure. His cheeks burned with embarrassment. He sounded, full on, like a helpless, horny slut! His friends would think he was some kind of pervert who was getting off on being raped by a giant slug. Yet as the slug pulsed again and another blissful gasp escaped his mouth, he wondered if it was true.
For all of Nate’s humiliation and concern for his appearance, nobody was paying much attention to him. Katherine was walking stiffly back toward Tim, shaking the slime from her hands. Tim was staring, captivated at Sarah who herself was wholly occupied with the invasion of her own entrails.
Nate felt the creature’s slippery tail slurp inside, and his asshole close behind. He stopped resisting the incredible feelings and indulged himself. Each squirm and every slither poked his prostate and pushed him closer to the precipice of pleasure. Having never experimented with anal before, the feeling was thoroughly foreign to him. He savored it. He leaned into it, and before he realized what was happening, he found himself teetering on the edge of an orgasm. He tried to take it back, to distract his mind and prevent the inevitable, but it was too late. His bowels spasmed and clenched with an unknown strength as his innards lit up with pleasure. He moaned loudly, cock flexing in time with his gut’s contractions, sending jet after jet of cum onto the spotless tiles beneath him.
The aliens watched dispassionately, chatting about about the pros and cons of the ship’s new shift rotations.
Once the slugs had fully disappeared, Doctor Sslsskss dropped to all six legs and inspected Sarah and Nate’s ravaged behinds. “That should do it. Now we wait.” He turned to the humans. ”When I leave, you will be able to move and speak freely, but you are not to injure yourselves or the others.”
He turned and led Klkss to the door, but paused. “Aren’t you forgetting something?”
The apprentice looked back at the groaning humans, contemplating. “The probe!” He scurried back and snatched the probe from the ground near Sarah.
“These sloppy mistakes will be the end of you, Klkss. . .” Sslsskss muttered. With that he tapped a few keys on his holopanel and the stables’ interior flickered back into existence around them. The aliens were nowhere to be seen. Tim and Katherine found themselves back in their stall, while Sarah and Nate were in the one adjacent. Even knowing it was some sort of hologram, everything about the environment seemed completely real down to the last detail. The air even smelled like dried straw.
Tim shouted, “Sarah!” and dashed to the edge of his enclosure. He tried to climb the wall into Sarah’s stall but was blocked by a forcefield. She and Nate were rolling on the ground, clutching their stomachs.
“Oh, God!” Cried Sarah, gripping at her ass, “It’s so deep inside of me!”
Nate rolled back onto his hands and knees and raised his behind toward her face. “Pull it out! Pull it out!”
Sarah gasped. “I -- I can’t.”
“Please! Reach in and grab it! I don’t care!”
“No it’s not that. It’s your asshole. . . it’s disappearing!” It happened right in front of her eyes. His pucker squeezed shut, and the wrinkles around it smoothed out. It gave one final twitch before becoming indistinguishable from the skin around it.
Nate groped at his hole but found nothing. “Ahh! It’s gone!”
Sarah reached back between her own cheeks and was relieved to find her asshole intact, though it gaped open from the ordeal. Several of her fingers accidentally slipped inside, and she shuddered. That felt good. She massaged her sphincter with her fingertips. Unlike Nate, she hadn’t felt any pleasure from the wriggling of the slug, but now her legs quivered in bliss. She inserted her pinky finger and bit her lower lip to stifle a moan. She now had four fingers buried in herself, but it wasn’t even a tight fit. The aliens must have really stretched her out. Maybe she could reach the slug! If she could just get a little deeper. . .
Sarah folded her thumb against her palm and pushed. Her asshole, still sloppy with slug slime, easily swallowed her hand up to her wrist. She grunted a guttural moan of delight, and everyone stopped what they were doing and watched.
Tim was transfixed. “Jesus, Kath. Can you reach it?”
Sarah didn’t hear him. Her asshole, and the bizarre bliss emanating from it, were her entire world. She wiggled her fingers, tickling her silky insides and sending sparks of pleasure shooting through her body, up her spine, down her legs. She wanted more. She curled her back, stretched her shoulder, and pressed her forearm a few glorious inches deeper.
Once again, she moaned loudly, erasing any doubts that she was enjoying herself. In fact, she had completely forgotten why she had buried her arm inside herself until her fingertips brushed against the muscular tail of the slug deep inside of her. She tried to pinch it, but it slipped away. She strained to reach, but her back was painfully contorted as it was, and she couldn’t get her arm any deeper.
Sarah sighed and relaxed, letting her hand slide back out to her wrist. What was the point in trying? Their bodies were already changing. She could feel her digestive tract rearranging around her hand. Her colon was straightening out, opening up, and the fleshy walls that were velvety smooth just seconds ago, were growing ribs and nodules that gripped her arm needily. She took a moment to rub the new textures inside of her and savor their heightened sensitivity.
“Did you get it?” Asked Nate, leaning in.
Sarah blushed and pulled her hand loose with a loud slurp. “No.” Embarrassed by her unusual display, she sat on the ground to hide her loose, changing asshole.
“Are you okay?” asked Tim, peeking over the wall.
“Well let’s see,” Sarah mocked, crossing her arms in front of her breasts. “First we go on the world’s most boring double date. Then, we get abducted by freakin’ pervert aliens who probe us. Then my boyfriend sticks a giant butt plug in me. Then my best friend lets a giant slug climb inside of me. Now I’m trapped in a prison on a spaceship, and my body being modified by aliens who don’t even really know what species we are. Did I miss anything?”
Tim was quiet for a moment. “You forgot the part where they put these ‘t’tssk’ things on our heads.”
Sarah threw her hands in the air. “Of course! How could I forget about my mind-control jellyfish? You know, the one that is making me stupider? So yeah. I’m doing just fantastic, Tim.”
“What is up with these t’tssk things?” Nate asked, running his hands along the rubbery pink crest on his head. “It feels like a part of me.”
Katherine grunted. “Ugh. I hate it when you say that word.”
“What?” Asked Nate. “T’tssk? That’s what it’s called.”
“Yes. It’s one of their words. Just think how easily you’re using their language. It should disturb you too.”
Nate rolled his eyes, turned, and mooned Katherine. “Look at this! You are talking to a man whose asshole just disappeared. Not having a hard time finding things to be disturbed about. In fact--” He winced as his stomach interrupted him with a loud, sustained gurgle. “Ooh. I don’t feel so good.”
“Neither do I. . .” Sarah groaned, clutching her abdomen.
Katherine squinted down at Nate’s behind. “Nate, you’re turning blue.”
Everyone looked, and sure enough, centered where Nate’s asshole used to be, there was a patch of sky blue skin. The color was spreading like an ink splotch, hair shedding anywhere it touched. Soon his entire ass was as smooth and blue as a blueberry. Sarah felt a wave of warmth as the blue skin crept around the outside of her hips. She watched her pubes fall to the floor in clumps as it spread to her groin.
“Well at least I won’t have to wax anymore.” She muttered, turning away from everyone and discreetly examining her pussy. Her inner labia had turned a dark navy, almost black, but the shape was different too. Her outer labia were merging together, almost as if they were being zipped up with a zipper. She ran a nervous finger between her lips and couldn’t find her clit or urethra.
Nate was also staring at his crotch, but he had given up trying to hide it. Just like Sarah, his curly pubes were the first to go. He cupped his balls as they darkened into a deep navy. His scrotum, tight and wrinkled from the cool air, smoothed out and sagged. His testicles throbbed and swelled, each heartbeat permanently increasing their size. His scrotum stretched taut around balls as large as hen’s eggs, and still they grew. Soon they were too large to fit comfortably between his legs, and they pulled back until they sat prominently beneath his asscrack. He reached behind himself and palmed one of his massive testes. He would have to be careful sitting down from now on.
Everyone stared openly as Nate’s cock underwent its own growth spurt. His balls’ midnight hue flowed down its length. It was visibly swelling as it flopped flaccidly in front of him. It fattened up until it was disproportionately thick and then stretched down, gaining length. Then it happened again, then again. By the end of the third stretch, it hung down to his knees and was as thick as a soda can. The growth stopped. Nate hefted its weight with both hands and gawked at it in disbelief.
“Holy shit! I’m a freak!” He exclaimed, touching and squeezing his new penis. The flesh was solid like he was erect, but instead of being rigid and straight, his shaft was flexible. A webbing of veins branched into existence across its surface, the main arteries as thick as his pinky. They were softer to the touch than the rest of his dick but still surprisingly solid. Next, the head of his penis flattened. His glans lifted and swelled, its edge scalloping into ridges. His urethra stayed relatively human-shaped, though it grew considerably, stretching to match the size of the rest of his cock.
Nate held his dick right in front of his face, staring in awe and terror. Then, a jolt passed through his loins, his balls clenched, and a jet of pearly semen spurted out and hit him right between the eyes. He dropped his dick in surprise, and it flopped down, slapping his thigh. The slimy cum stretched all the way from his nose to the tip of his cock. It was extremely viscous.
Tim and Katherine covered their mouths in disgust and turned away, but Sarah was transfixed. Sitting where she was, Nate’s dick was dangling right in front of her face. She knew she should have been disgusted, but instead she was curious. She wanted to reach out and see how it felt in her hand. Was it warm? Smooth? Heavy? She wanted to lift it to her nose and see if it still smelled like a human dick. More than anything, she wanted to taste that slimy cum and see if it was salty and bitter or sweet and syrupy.
She reached a hand between her legs to masturbate, but everything felt wrong down there. Her outer labia had continued to close up, and now there was now nothing more than a mound between her legs with a tiny opening at the top. She touched the hole with a fingertip and it dilated open. Black ribbons of labial flesh bloomed outward like like flower petals. Sarah poked and prodded through the slippery tangle of labia, but she couldn’t find her vagina, nor did she find the touch pleasurable.
A small, muscular tube emerged from the center of it all and strained forward a few inches before relaxing. A crown of three fleshy nodules surrounded an opening at the tip, looking like the head of the bioslug that she could still feel squirming in her gut. It looked almost as if her vagina had prolapsed, but it didn’t hurt. She tried inserting a fingertip, but it was uncomfortable. She pinched the tip of the length, pulled gently, and, to her surprise, it extended. She was able to coax another foot of the strange organ out of its home before she let go and watched it pull back into her body. Once it was fully retracted, her outer opening pursed and closed again, hiding the whole affair away until the only hint of it was a mound between her legs.
Sarah looked back at Nate’s dick. There was no way she could fit that thing inside her changed pussy. It was nearly as big as a horse’s cock, and it was starting to resemble one. Two pronounced medial rings formed on his shaft. The blunt head looked more like a horse’s than a human’s as well, save the human-like urethra. The edge of his glans sprouted three fleshy nodules that quivered and stretched like they had a mind of their own. She remembered feeling similar stalks popping inside of her one at a time as the slug pushed into her asshole. It hadn’t been enjoyable at the time, but now she found the thought enticing.
Nate managed to get the cum off his hands by wiping it onto the wall. He glanced back down at his dick and was surprised to see that instead of growing, it seemed to be getting shorter. But it wasn’t shrinking; it was retracting back into his body. He could feel its length sliding into his abdomen, filling up some new passage that served as its home. The whole time, it remained just as hard and flexible as ever. It stopped leaving only a few inches of shaft and the flat, ridged head dangling out of his new sheathe.
It was then that he noticed Sarah standing and brushing herself off. The skin from her knees to her hips had turned robin’s-egg blue, but other than that she seemed relatively unchanged. Suddenly, he felt very self-conscious. He clasped his hands over his crotch and turned toward her so that she couldn’t see his swollen testes. She reached a hand back to her ass, then furrowed her brow and got a troubled look on her face. She noticed him staring but didn’t try to cover herself.
“Nate,” She said, softly. “Come here.”
Nate approached, balls shifting behind him with each step.
She waited until he was close, then spoke quietly. “Nate, I want you to look at my ass and tell me what’s happening down there.”
“What?” Tim wailed suddenly. “I can do that for you, Sarah! Don’t have Nate do it. Let me.”
Sarah glared at Tim. “I want Nate to do it. He’s going through the same thing as me right now, and besides, he’ll be able to get a closer look.”
“But.” Tim swallowed nervously. “Look at him. He’s turning into some kind of sex monster! His balls are bigger than my fists. There’s no telling what he’ll do. He could rape you!” He turned to his friend. “No offense, Nate.”
Nate frowned. “Hey, man. That’s not cool.”
“Yeah, Tim. Not cool. And how could you say that? You’re the one who probed us against our will, not Nate.”
Tim was taken aback. “I didn’t want to. I was being mind controlled!”
“Well. . . whatever. It’s my choice who I get to examine my ass, and right now I want Nate. If you want to help, you can leave us alone.”
“But. . .“
“Come on,” Katherine said, stepping away. “Let’s give them their privacy.”
Tim opened his mouth to respond but thought better of it and followed Katherine back into their stall. The walls were high enough that it was difficult to see much without stepping right up to them. So suddenly, Sarah and Nate were alone together.
Sarah turned to Nate and rolled her eyes. “I’m sorry. He gets really jealous. You know he didn’t mean any of it.”
“No, he was right. I mean look at me.” Nate uncovered his privates and gestured to himself. Sarah had already seen his changes, but took the opportunity to get another eyeful. “I am turning into a monster.”
She placed her hand on his shoulder. “You’re not a monster. Or if you are a monster, then so am I.”
“Thanks, Sarah.”
“No problem. Now, would you please tell me what the hell is going on back there?” She said, pointing a thumb behind herself.
