Story: Change-Switch Fever

 

Things were bleak inside the quarantine, as by now pretty much everyone had it. Oh, wait, no. Bleak was the wrong word. Pornographic! Yes, that's the word. It was outright pornographic there. By this point, the fever had functionally guaranteed that everyone had their clothes off, and even if you weren't having sex you were still getting covered in a thin layer of sweat. Which made the naked skin gleam, which naturally drew more attention to it, which made people horny, and there wasn't much of a point in separating the boys from the girls because-  

Achoo!

Suddenly there's a girl among the boys, or vice versa. 

In the middle of it all was Rito Yuuki, once upon a time a boy who got really, really nervous around girls. He currently had... let's see... he was counting six girls right now crawling all over him wanting a piece. He felt super groggy. Sometimes one of them would sneeze and become a boy, and the girls would split their attention. Sometimes he'd sneeze, become a girl, and... the girls would still be all over him. Including those that were boys.

"Lala," he muttered, while Lala was licking the sweat off his neck. "Do you have to do that?"

"You were doing it to me when our genders were flipped," Lala complained.

"Yeah, but..." Rito sighed. It was so annoying at this point. He couldn't stop himself from having sex, but at this point it was getting weirdly boring. It wasn't that it felt bad. It wasn't that they were starting to hurt. It was more like they were basically doing it for the same reason they were breathing. Reflex. Reflex alone.

Honestly he was starting to get a bit worried that, after this was all over with, their first night back out there again, at home, he'd wind up knocking her up or something. Actually, he wasn't entirely convinced none of them weren't going to end up pregnant by the time this is over with.

On the other hand, any nervousness he had about the female form was gone. Forever.

Suddenly, the door to the gym opened up wide, and the orgy was interrupted by a brand new presence. Had someone broken the quarantine? As it turned out- no! It was... some kind of robot that looked sort of like Lala?

"Greetings! Everyone!" the Lalabot said, cutely saluting everyone. “I am here to maintain order, administer medical countermeasures, and ensure a balanced romantic comedy experience!” she chirped, her eyes twinkling with coded chaos.

"Oh, god! She's soooo hot!" said a girl that might have once been a boy. "Achoo!" and now they were a boy again. "Gimme some of that!"

They dove for the Lalabot, which deftly dodged around them, produced a thermometer, and stuck it right where the sun didn't shine. To everyone's mild discomfort, the boy seemed to like it.

"Temperature is higher than normal for humans," the Lalabot remarked. "Please do not attempt to have sex with me, please. My insides are metallic. The experience would not be pleasant!"

... Annoyingly, that made Rito really want to have sex with the robot even more. Which was a completely irrational feeling probably brought on by the virus itself.

"Shameless!" male Yui Kotegawa said, licking his lips before trying to pounce on the Lalabot... To no avail as it effortlessly whirled around her. "Absolutely shameless! Flaunting that hot metal ass in here and expecting it to go untapped!"

"Is it weird that I kind of prefer her like this?" Haruna whispered.

Rito thought it over carefully from all angles, watched Yui make several more attempt to stick it in the Lalabot, which were failed because it's a robot based on the thought patterns of a Deviluke taking things seriously, and nodded his head.

"Yes, it is very weird that you feel that way," Rito said.

"Darn, I was afraid of that," Haruna sighed. Then she sneezed. And so did Rito. Moments later Rito had her lips around Haruna's dick. Hrm... It did taste kinda nice, if she was being perfectly honest...

Outside the quarantine, a certain pair of twins were in a quite rightful freakout about the whole situation. The forcefield was holding. Not a microbe was allowed to leave the premises. Energy though, that was another matter entirely - and thankfully, that seemed to be enough.

"We need a sample of the pathogen to cure this.." Momo muttered to herself, pacing around in the street just outside the school grounds.

"No, not just one sample!" Nana corrected. "It'll take more than that. We need to be sure we've got the right one. Remember, there'll be all sorts of weird microbes in the air."

Momo came to a stop and looked back. "You know, that is something that isn't normally dealt with in sci-fi," she said. "Our immune systems are completely alien. Human beings have evolved alongside things like the common cold, or the flu, or other assorted bacteria and viruses. But they've not evolved alongside the ipsy dipsy or the ultrix contagion."

"Urgh, I still remember having ultrix the first time..." Nana grumbled. "My eyes felt like they were screaming, and my nose kept on whistling the entire time... But wait, humans aren't used to that sort of sickness, so..."

"Maybe their immune systems are more robust than we figured?" Momo shrugged. "Or maybe the illnesses are similar enough that our immune systems both figured it out so quickly that we hardly noticed catching them? Either way, this pathogen is obviously nothing like anything made on Earth. Or out in the solar system. It's a combination of both."

Indeed. That was the only thing that made sense. A hybrid illness of some sort. Indeed, it is possible for a hybrid virus or a hybrid bacteria to exist, at least according to Earth studies. So why not whatever it is they have in the greater galaxy combining with either of them to make something new?

Hrm? What's that? You're wondering why the girls don't know that stuff already? Well, to be frank, one of them was intrigued by plants and the others by animals. Microbiology is neither. That was closer to Lala's field. Which is why they'd activated a special emergency robot that had her thought patterns.

Was it especially strange that they had access to such a robot. Listen. Buddy. You don't seem to understand these sisters. They might be fascinated and intrigued by plants or animals, but there was one thing they were interested in way, way more than that.

Their brilliant big sister.

So it was only natural that they'd do something like this. And by natural we mean 'freaking weird bordering on obsessive compulsive'. They made themselves a robot, in secret (but Lala actually totally did know about it, pretending not to), then in her sleep attached a couple of diodes to her head so they could monitor her brainwaves and copy them into the robot.

It's good to remember sometimes how freaking weird this family is.

In any event, it was time for the vultures to descend. And by vultures, we of course mean the news. I mean, it's kind of hard to throw up a giant quarantine zone around an entire school and expect no one to notice. That’s exactly the kind of thing that screams “local interest” to the 6 o’clock crowd. Helicopters in the sky. Reporters in hazmat suits. A suspicious lack of explanations from officials. You know—typical Tuesday.

"Masu D. Komi of the GottaKnow news!" said a tall round person wielding a microphone. "What can you tell us about the ongoing plague?"

"Ah, well," Nana began. "It seems to replicate the effects of a particular alien -"

"Does that mean we'll all gain adorable yet extremely sensitive tails?" Komi interrupted.

"No, no, you switch genders when you sneeze," Momo corrected.

"I see, I see! Pushing the trans agenda again!" Komi gasped. "Oh, at a school of all places! What are you doing to help contain these degenerates!"

Believe it or not but Komi was having an off day. Normally he'd be a lot more openly manipulative than this.

"Um, we've sent in a special robot which should be able to do a proper analysis on this new pathogen?" Nana said.

"Indeed!" Momo said, having procured glasses and a labcoat from somewhere. Never mind that she was also wearing protective gear, full on advanced hazmat suits et al, she'd found a way to put them on without taking off the gear. "For this reason, the people of Japan - no, the people of Earth are in good hands! In fact, why don't I quickly check in on what is going on with the robot right -"

Her faux professional demeanour dropped when she checked her handheld monitor, her eyes wild. If you looked really closely, right into her eyes, you might have seen the reflection of what she was glaring at with absolutely rigid horror.

The robot was busy, you see. It was acquiring body fluid samples, and doing so in the most efficient way that it possibly could. How so, you ask? Why, by opening its mouth and putting on a big ol' suck! Bobbing its head back and forth repeatedly, over and over again, and the thing that was really breaking Momo right now?

The cock it was collecting body fluids from was that of her own gender bent big sister. Who was making a really weird facial expression while grabbing the robot's head. A facial expression which she was certain would wake her up in the night some years from now, as fear and horror washed over her body, the recurring nightmare striking yet again. The sweats, the night terrors, the sheer trauma of it that was in the here and now burrowing its way deep into her cerebral cortex (or the Deviluke equivalent thereof) waiting, lurking, like an unwanted guest it would inevitably come out.

Yet she dare not show a hint of this right here and now, so she must do the most damaging psychological thing that she can possibly do. Pretend she didn't see that and start swimming in denial, baby!

"Ahem!" she said. "It should go without saying that our robot will need to perform careful medical analysis, and it would be inappropriate to broadcast an examination live without the subject's consent." She winced at the word 'consent' passing her lips for some reason.

And why was that? Well... It did have quite a lot of body fluid to gather up, didn't it?
