Story: Change Switch Fever

 

 Is there anything hornier than an unchained tsundere? Think about it. Think about how repressed they are. Think about how they're so bubbling over with affection that they're afraid to let it out. Calling it a 'bursting dam' is a bit of a cliche, but that's only because of how apt the metaphor is.

Well, right now the tsundere was off the chain. The dam was bursting, the water was flowing freely. Yui Kotegawa (male) was letting it all out, all that repressed desire, and Rito Yuuki (female) was a prime target for it. Where Yui (female) was a busty long legged sexually repressed cutie and Rito (male) was a kinda adorable woobie, with their genders flipped Yui was a broad, muscular powerhouse while Rito... was every bit as cute as before. Seeing that cute girly body grabbing onto that muscular, lean form was... quite the surprise for Lala, to say the least.

Yui made eye contact with Lala and didn't stop her thrusting for even a second. Instead there was a weird intensity around... him? Her? As she regarded Lala's body with obvious perverted intention.

"I was always jealous of you," Yui said. "Babe, you got a killer body and no shame in showing it off. That always annoyed me, because I didn't have that confidence. I was ashamed of my own body, evne though, thinking about it now, I was a fucking hottie! Come on, join in! You wanted a harem where everyone could have a happy ending, right? Bring me that Deviluke ass!"

Now, what sort of response might Lala have in this situation? Might she bring her hot Deviluke ass into a threesome? Many reading this would surely prefer that option, though it is hardly logical for her character without something else compelling her to do so. Might she run away in tears? Again, that's not her character.

Instead, Lala zipped over, slapped something on Yui and Rito's heads, and then drifted back while nodding her head like this was not a big deal.

"Just as I thought," Lala said. "You're both really hot."

Not quite what either of them were expecting. It was true. They were both extremely hot. Only a fool would deny something like that. However, after a moment Yui realised the context that Lala meant, because she was putting on a mask.

"You're obviously sick," Lala said, wagging her finger. "Really now, I don't mind sharing Rito but the two of you should be resting up! Not exerting yourselves like this. Now, let's see. I can't think of an illness that causes a person to both switch genders and become extremely lewd... I mean, there's no way Yui wouldn't at least want to go on a date first whether male or female, so there must be something very strange going on here. I should check with Doctor Mikado, she might know something. Now, you two break it up and lie down, give your bodies enough time to recover..."

Yep, that was the response. Lala is a little bit lewd herself but more sort of innocently lewd if that makes sense. She had already instructed Peke to change into a cute quarantine outfit, which wound up looking like a whole body skin tight pink costume with a plastic bubble around her head.

"Ah! Oh no!" Rito moaned, clutching desperately onto Yui's body. "Lala's setting up a quarantine zone, and is bound to use one of her weird inventions!"

Yui knew what that meant by now. Something was going to go haywire. It always did where she was concerned. While her inventions were brilliant, and often did what they were meant to, the trouble was that they often did things they weren't supposed to as well. Quite often doing that latter category better than the former. Furthermore, since that latter category was often many magnitudes bigger than the former, it also made it quite impossible to predict what, exactly, would go amiss.

"Alright! Let's get you in this bioscanner!" Lala said. Oh, oh no. Horrible images assaulted Yui's imagination just now. Perhaps there would a Fly-esque accident where her body would fuse with that of a random insect. Or perhaps it would transform her body in some other way. Or it might create copies of her, hordes of copies of her new masculine form. Then, she would sneeze and transform back into her original girlish body, surrounded by hunky masculine brutes who would surely, shamelessly, ravage her body until she -

Nutted inside of Rito. Right. Well. The plan <i>had</I> been to scarper before Lala picked them up and dumped them in the bioscanner, but... Boys, have you tried to actually run after nutting? Hell, have you tried to remain standing immediately afterwards? It's doable. It's just not as easy as it normally is. Yui was riding high on afterglow, making it all too easy for Lala to use one of her devices to wrap around Yui's body, carry 'him' into the bioscanner, accidentally jerk him off (it wasn't meant to do that, and so as per above, it did exactly that) and put him inside without risking Lala getting infected through extended contact.

"Achooo!" Yui sneezed violently, providing a helpful sample for the the machine. "Ah! Ah! What did I do?! I shamelessly - I shamelessly violated him! Oh! Oh, do I have no self control? Am I truly a wild beast save for an X chromosome?"

"Hum, it looks like a viral infection of some kind, sure enough!" Lala said. "I should get this scans to Doctor Mikado, I can't make heads nor tails of the details. I could probably make something to mask the symptoms, but it wouldn't actually cure you."

"Cure me! Erase my memories!" Yui wailed. "Ah... No, when I think about it, I would probably do it again! And - And don't misunderstand what I said before! That was something I said only be-because I was in the heat of the moment, I don't actually desire your body in a sexual way!"

"Right, right, of course not," Lala said. "You were feverish. Though, if you had been sincere I would at least want to go on a date with you both first. That is the proper way to do things."

Lala turned her attention away from the guilt ridden girl and onto the scans. It was quite fascinating. This was certainly not like any human disease. Virus like, yes. However... It seemed to be stimulating the body in a way that a virus does not. This hormonal output wasn't necessarily connected to the gender switch, and is likely a key factor in the high arousal of those infected. It was quite fascinating actually. There was no doubt in Lala's mind that this disease came about by chance, but the details of it were -

"Lala! I still feel - Woah!"

Ladies and gentlemen, Rito Yuuki, the clumsiest man on Earth. She'd stumbled to her feet while Lala was reading the summary, tripped and cartwheeled over 'her' own feet managing to, somehow, kick Lala's helmet off and land pussy first right on her mouth.

Watching this from outside, Yui sighed wearily and facepalmed herself so hard she wound up knocking the bioscanner over.

As for Lala, her change hit her right away as she sneezed the moment Rito was of enough presence of mind to climb off her. She grew an extra foot, her rounded features grew harder and more chiselled. However! Where Yui had become a tall handsome stud, Lala came off more like... well, something in between Yui and Rito's male form. A cute studly woobie-esque hunk of a boy.

"Ah!" Lala gasped, surprised at how deep his voice sounded. "Oh dear. This could be bad."

"I'm sory," Rito said, seductively. "Would you like me to... make it up to you?"

"L-Let's go on a date first!" Lala insisted. Though the erection was telling a quite different tale. "Oh gosh, this is even more contagious than I thought. Ah! I feel so - So hot! We need to quarantine the school to keep this from getting out!"
