Story: Change Switch Fever

 

We are all surely familiar with the car crash effect, yes? Everyone turns to look. It's not like you actually want to see anything, but you can't help yourself, right? That was the situation Yui was in, except there was an important distinction here - rather than something grotesque, she was trying not to look at <i>something very, very hot</i>.

"Rito Yuki! Somehow you're even worse as a girl!" Yui yelled, while Lala (now male and very, very erect and... quite big too) struggled to get away from the genderbent clumsy pervert. Shameless! Utterly shameless! Look at the way that she was draping herself all over him, it made her embarrassed to be a girl! It was wrong, it was grotesque, it was - It was shameless, pure and simple!

On the plus side, Lala had managed to set up a quarantine for them, which meant that this wouldn't spread any further. Unless you counted the people on the outside who were already infected and - Panic time! "Lala, quarantine zone!" she yelled. "I believe there are other carriers in the school already! We need to hurry, we need to keep this contained!"

"Eh? Other carriers," Lala yelped. "Rito~ Ah, not my ear. Oh, I can feel your breasts through this suit, they're a little bigger than mine, I think..."

"Focus!" Yui snapped her fingers. "Honestly, the pair of you! We have a crisis here! If this gets out, the entire planet might become a never ending gender flipped orgy!" Oh, that was a nasty feeling that passed through her body just now. Very unpleasant. She really didn't want to imagine that, at all! "Honestly now, be like this at home if you have to be, but not when there's a world ending crisis going on!"

"Ah... You're right," Rito said. "I'm sorry Lala. It's just... I'm so horny like this, I can't take it. So hot all over... It feels like I'll burn up if I don't have sex as soon as possible."

"Alright, I'll expand the area of the quarantine zone," Lala said, rummaging in his suit for... something. Ah, he seemed to find it. A remote control of some sort, if she was any judge. "Ta-da! Now then, let's get this -"

And then, not for the first time, nor for the last, Rito tripped over absolutely nothing. What happened next was so astonishing that it was almost a work of art. Rito went and pulled down Lala's trousers, leaving him fully exposed (oh gosh, Yui couldn't be allowed to see that! E-Even if it was bigger than her own boy form's - What was she thinking?!) and then somehow Lala's tail got caught in between Rito's cleavage.

This caused the gender bent alien princess to go cross-eyed all of a sudden. Oh no. Yui vaguely recalled something about... About how Lala's tail was an extremely sensitive area for her. Having it touched or grabbed or caressed was apparently enough to leave her in an extremely vulnerable position!

"R-Rito, let go!" Lala whined and grunted, while his dick grew somehow even more erect than it already was. It - It was getting bigger?! N-Noooooo! So shameless, so thoroughly, absolutely shameless! His dick was throbbing now, it looked a bit painful. Like it was telling Lala, warning him that if he didn't use this right here, right now, then it would explode in a not fun way!

Yui, being capable of basic pattern recognition, saw where this was going and immediately stepped in to interfere. "Rito Yuki! Stop rubbing his tail with your stupidly big chest! You're going to make him -"

And, of course, this is where the clumsiness of Rito Yuki comes into play and makes her stick her foot out, tripping up Yui and sending her sprawling on top of Lala's remote. Breaking it, and then toppling on top of the other two, with her winding up staring directly at Lala's penis.

You've never seen a truer shade of scarlet. Now it was Yui's turn to look like she would burst! P-Penis! She was looking right at a d-disgusting, erect penis, right there in front of her! Th-This was bad, this was very, very bad! She felt like she'd stumbled upon a king cobra, and was paralysed in place. She didn't know what to do with herself!

Fortunately, Rito had a pretty good idea, and went right for the pussy. Licking Yui tenderly, like she might an ice cream cone. Of course, the girl went rigid at this, as a whole new level of fury and disgust flowed through her... followed quickly by arousal. Much to her own irritation.

Her imagination went into overdrive here. Was it possible that - that this weird illness didn't just make you hornier in the other form, it also made you hornier in your usual body? If it was because you weren't used to it in the other form, less capable of controlling it due to lack of familiarity, then that might explain why she was feeling this way. Sh-She should be kicking Rito away. Telling her off. Doing something. Anything! Just to get away from this!

And yet, instead, she caught herself thinking about what she had done as a boy to that girl. She had - She had definitely, without question, done some very shameless things to her. Things she had apparently quite liked. That both of them had enjoyed a great deal. Trembling, Yui's eyes glazed over, her mouth opened and - In it went.

====

Lala was quite determined to escape from this situation... right up into his tail got caught between Rito's breasts. That had been pretty incredible. Unlike anything he'd ever felt before. However, that didn't mean he was going to simply roll over and screw Rito into next week or anything so absurd. It was a moment of intense stimulation, not enough to drive him over the edge or anything like that.

Inexplicably receiving head from Yui while his tail was caught between Rito's thighs, while Rito was sitting on his face and very obviously licking Yui's pussy, that was certainly enough.

This was stupid. It was so dumb. The fact that they'd wound up in this situation at all - fuck, yes, please, right there - was so unlikely it bordered on the preposterous. Ah! Ah! Ah! They should have waited. They should have - Should have maybe gone on a date or something first maybe? 

But on the other hand these two girls were total babes, and they obviously wanted it, and besides which he knew them quite well so why not go along with it see where this went, and that's why Lala wound up having a threesome with Rito and Yui despite himself.

The mental state the three of them were in was obviously a bit confused. All three of them had a strong mutual attraction that was being hammered out onto the surface, and their inhibitions had gone to sleep. Perhaps an effect of the fever. Of course, it should be obvious that Yui was attracted to Rito, and that both Lala and Rito were attracted to one another, and even that Rito might think Yui was kinda cute... But Yui to Lala?

Well, yes. Yes, she did. She had an unrequited, repressed crush upon the daughter of the most beautiful woman in the galaxy. She admired her can-do attitude, even as she disliked the lack of common sense.

Now, this is where the attentive will stand up, raise their hand and say "hang on, she was a girl. Her usual form. Doesn't the virus only make you horny if you're switched?" Indeed, that is how it appears to work. That is... Unless you are trapped with two people you happen to be attracted to, both of whom happen to be in their opposite form. The sight of them having sex had awakened something in her, set off the contagion within, and whispered in her ear like a devil on her shoulder.

'Go ahead,' it whispered. 'It's all my fault anyway. You're sucking Lala's dick and loving it - because a weird alien infection is making you do it. You're not normally like this. Go ahead. Have fun. Then blame me.'

That's right, she thought while enthusiastically bouncing her face on that dick like it granted immortality. The pleasure she was feeling, the utterly shameless pleasure... it wasn't her! It was this sickness! It was making her behave in a completely sick way! Yes, that made sense. It's why her male form had said such lewd obviously untrue things about Lala. It's why she'd given Rito a <i>good hard and righteous dicking</i. And would do it again the next time she sneezed.

Which would be much sooner than she thought.

"Achooo!" Yui sneezed, and in so doing switched right back into boy form, who sheepishly - yet also confidently and brashly, it was kind of a conflicted experience - climbed off Lala's cock and turned his attention towards the sexy girl licking eagerly at his taint. "Hehehe, not bad..." Yui said, quite shamelessly. "But Lala..." He wiped his fingers off the floor, bringing up a small trail of dust. "Think fast!"

He pushed Rito away, revealing Lala's stunned face, and then he dumped the dust right onto his nose, causing the alien to sneeze right away. "Achoo!" Perfect! He wasted little time in finding her tail and grabbing onto it, keeping a nice tight hold.

"Hrmmm... I'm in the mood for a threesome," Yui licked his lips. He made a jerking motion along Lala's tail, making her shudder in delight. "How about it? Let's all have some fun together."

"N-No, need to establish quarantine!" Lala moaned.

"Awww, why?" Yui asked. "Aren't you having fun? It's so... fucking liberating, isn't it?" Without hesitation, Yui drew back his hips and slammed his dick right into Lala's pussy, all the way to the hilt, making the alien Princess moan in the process and ensnare her ankles around Yui's waist. "No more dancing around, pretending we're not heading this way anyway," Yui leaned over and kissed Rito right on the lips. Finding an eager pair of feminine lips meeting coming right back. "This is so much better for everyone. No more inhibitions! No more holding back. Now everyone can be... shameless."

"Mmmm... No..." Rito said, sounding a bit sleepy. "No, that's wrong. That's not the Yui I know."

"Well, no, that Yui was - "

"Mindful of others, knew where her limits were," Rito said. She stepped back, frowning. "Is this really what you're like when you're horny? I don't like this. You're so... <i>fucking hot</i> but with a personality like that... Leave Lala alone! You - You fake Yui!"

Sometimes, it takes having a mirror held up to yourself to realise what was happening to you. Male Yui was starting to realise that he was going a bit too far here. Would it be enough to snap Yui out of it? Would it even matter, given that they had inadvertently destroyed the means of setting up the quarantine?

That depends entirely on which option gets followed up on, doesn't it?
