Story: Happosai's Corrupting Influence

Were you ever at some point just having a perfectly normal day, without having to deal with bullshit superpowered beings or shadowy conspiracies or what have you? No crime to stop, Kuroko's not been particularly flirtatious, Misaki must have found some new toy to torment. It really doesn't seem like anything can go wrong today. To Misaka Mikoto this was a rarity. Something always seemed to pop up, but today was a good day!

Then suddenly you realised that Murphy does not like to be taunted, especially if someone realises after the fact that they just taunted Murphy and the whole thing gets pretty damn repetitive until suddenly you're freakishly aware of every single shadow on every single corner -

Like... There for example! Misaka Mikoto whirled around just in time to see it, a little goblin... <i>thing</i> bouncing around and cackling like a lunatic. She took aim and shot a blast of electricity towards the disturbing being. But to her surprise and defiance to common sense, the figure jumped into the air, easily dodging the miniature lightning bolt. Consider what that means. Lightning is fast, incredibly so. To dodge her attack like that was ridiculous. Certainly fast enough that normal humans would have almost no chance to react to it. Her initial thought was that he was a new esper, and she made ready to hit him with a modified electromagnetic field -

Then the creep flipped her skirt, gave a disappointed "Aw, boxers? Boo!" And off he hopped down the street.

"Hey, you!" Misaka yelled while pushing down her skirt. Oh! Ohoho! "I can't let a criminal like you -"

"Uwaaaaa!"

Huh? That sounded a lot like - Misaka turned around just in time to be bowled over by a big, huge and <i>unfair</i> pair of tits that were attached to - of all people <b>her romantic rival</b> Index!

"Oof!" Index gasped when they had finished toppling over. The Railgun was flat on her back against the pavement trapped within marshmallow hell, annoying nun edition. It was a rare thing indeed for her to be scared to move, but right about now Misaka was absolutely terrified of moving and touching those ridiculous mounds. They were way too big to be sexy. What sort of man could find appeal in a pair of udders like that?

This was where she realised she had been holding her breath as well. Not that it really helped much, as she felt something trickle out from Index's robes and onto her lips. She unconsciously licked her lips before realising what it might have been. It tasted... Good.

"Ah! Sorry, I didn't see you there!" Index climbed up, extremely apologetic and prostrating herself in genuine regret for her behaviour. "It was extremely rude of me to - Oh, it's just you Short Hair. Never mind my apology. I must resume my chase."

And off she goes with those big, ridiculous floppy boobs just bouncing around uselessly. "Blegh, learn some manners Silver Sister! What happened to your chest anyway? Get in a fight with a balloon pump and lose?"

Index puffed up her cheeks, stopped jogging off then started jogging backwards to stare right into Misaka's eyes. Sparks flew between them, and for once Misaka wasn't doing that deliberately. Partly because her vision kept on flicking down to that damnable chest. Ugh, that kind of growth clearly wasn't natural. It was disgusting! It was gross. It was vile. It was...

"I know what this is," Index nodded. "It is called the green eyed monster of jealousy."

"I thought the green eyed monster was greed..."

"Hmph! Shows what you know!" Index huffed. "That strange old man somehow did this to me, and made me hungry for something other than food. Touma promised to feed it to me if I caught him, so don't get in my way!"

Touma promised...? Misaka fidgeted a little there and she took another deep breath. At the back of her mind that strange intoxicating taste lingered and she craved another bit of it. But at the forefront of her thoughts she was thinking about that idiot Touma and that goblin from earlier.

"By old man, you mean a tiny little goblin with a penchant for flipping skirts?" Misaka asked.

"Ah, you have seen him?" Index asked.

"Yeah, that bastard's fast and slick! He even managed to flip my skirt, the creep!"

"That poor old man," Index whined. Ooh! That troublesome little... Misaka grabbed hold of Index by her shoulders and pushed her into a nearby alleyway. "What are you playing at now?"

"That old man did something to you, right?" Misaka asked. "Let me take a look. Rushing off half cocked is just gonna cause us trouble in the long run."

"Very well Short Hair," Index said. Her voice and body language was dripping with reluctance. "You may inspect to your leisure, but I must insist that we locate that old man quickly. My hunger grows more fearsome by the moment!"

"Your hunger is a beast without end," Misaka snarked. She pulled those robes down and... She had been wrong before. They weren't ugly, or gross or disgusting or whatever other words she had used. They were... Enthralling. She blinked in disbelief. The Railgun's hands lifted up and copped a feel, unbelieving of what it felt like. She squeezed the warm yielding flesh - and then a squirt of white liquid shot out of Index's nipple, landing straight in Misaka's mouth.

The next thing she knew her lips were around that nipple and she was sucking on it for all it was worth. Sucking mindlessly, hips bucking without any care or consideration for her surroundings. It was funny really. She could resist normal attempts to control her mind, inasmuch as mind control is a normal thing. But those forms of mind control relied on electromagnetic manipulation of the brain. That was like trying to control the ocean by tossing ice cubes at it.

This was a combination of chemistry and actual magic. Still, after a little bit of exposure to it Misaka's brain did spark... something that told her to back off. Which she did with milk dribbling down her chin. Index was staring at her bleary eyed, biting her lip.

"That... sated my hunger a little," Index moaned. She hefted up her tits and Misaka felt it spike down her spine, the urge to continue where she'd left off. But no, instead she backed away. "Please take more," Index urged. "I'm still hungry!"

Then she felt... Something. Misaka gasped, there was a tremendous heat in her chest. Pressure from within that felt good, felt amazing, felt... Alive. It was a pleasure unlike any she could have dreamed of, and she forced her own brain to inhibit her pleasure response to make sure she stayed sane. It was the only way she could keep it from happening.

So instead of enduring the orgasmic bliss of her breasts swelling up underneath her uniform she felt a muted version of the same. It was all that she could do in the end. Misaka the Railgun, the Ace of Tokiwadai had always had that complex. Girls with bigger chests making her feel inadequate. Now she was experiencing a growth, rapid and pleasant that at once made her happy yet also afraid.

"Index! There you are!" Touma yelled, rushing into the alleyway at just that moment. "Ah... Misaka? He got you too?"

"Noooo!" Misaka whined, and off she ran with her arms across her new chest. It was a bit of an irrational response, all truth told but somehow she could not bear the thought of him  seeing her like this. It was only after she stopped to catch her breath a few minutes later that she thought it through in more detail. She'd run away from the boy she had a crush on because her boobs had undergone significant growth, and left him behind with her romantic rival whose breasts had also undergone the same kind of significant growth.

"Gah! What am I, an idiot?! What was I thinking?!" she yelled to nobody in particular. Her hands shot through her short hair rubbing furiously at her scalp. "Think, stupid! That was your perfect chance! You could have really made something of this and you blew it!"

"Perfect chance for wha~at?"

Misaka choked on her own spit and slowly turned around. To her horror and dismay she found herself looking right into the eyes of a girl called Lessar... And those eyes weren't making contact with Misaka's, not by a long shot. "So?" Lessar asked. "How did you get <i>those</i>?"

<hr>
Have you ever heard the saying "absence makes the heart grow fonder"? Well, that was the tactic being employed by Shirai Kuroko today. She was giving her dearest Misaka plenty of breathing space today. It was a pretty devious strategy. Stop being flirty for a day, make her miss it and therefore appreciate it all the more when she got it again!

"Gah! Index, cover those up! We need to talk about what happened with Misaka just now!"

That was Touma. Talking about Misata with Index. Just as Kuroko was walking by a certain darkened alleyway. Consider her interest rating at level 5.

"But Touma! It sates my hunger! Please feast as much as you like."

Ah... Now that didn't make any sense at all. The teleporter looked up, found the building next to the alley had a flat roof and then moved quickly up there so she could get a better look and hear what they had to -

What the hell happened to Index's chest?! Kuroko instinctively pawed at her own flat washboard. Why, if she had a pair of big milky titties like those even Misaka would be left lovelorn and mewling, curled up in Kuroko's lap while suckling at her splendid nipples.

"P-please don't tempt me," Touma pleaded. He was resolutely keeping his back turned to her. "Index, this behaviour isn't like you. That old man has done something really strange. We need to find him before he does something weird to anyone else!"

To that Index stepped back and pouted. "Fine, if you insist." The suddenly busty nun sighed and gave her mammoth mammaries a heft. "Ooh, they feel so full! If only I could empty them. Nnng, this hunger is so strange! I do not understand why milk is coming out of them. When Misaka took a sip, that was when her breasts began to swell up as -"

That was all Kuroko needed to hear. Her eyes shone up with mischievous, naughty stars and she teleported down to the ground, right behind Touma and in front of Index. Not the nipples she would like to lick, but the thought that Misaka had feasted on these - that was worth the asking price of admission alone!

Actually never mind. The taste of this milk was divine as well! Oof, no wonder even Misaka couldn't resist. One drop and you'd be hooked for life. She guzzled it down ravenously, feeling a warm sensation fill her body.

"Ah, no! Kuroko, where the hell did you come from?!" Touma yelled, trying desperately to pull her head away from this nipple. Not happening. Not ever, ever happening!

"Oh Touma!" a familiar voice cooed from nearby, interrupting Kuroko's feast."Look at what I've got now!"

"Huh? Lessar?" Touma grunted. "What do you waaaaaa -"

Cue a nosebleed powerful enough to rocket Touma off the ground, and there we go.

This was how it came to be that Touma was surrounded by four extremely busty and horny girls in a dark alleyway in a puddle of his own blood. The sight of Lessar skipping into the alley with tits bigger than her head while being pursued by an angry Misaka with equally large tits, while right in front of him Index was breastfeeding a suddenly busty and moaning Kuroko... It was all just a little too much for him to take, and I think we can all agree on that being a pretty decent limit for the male libido to withstand.

"Aw, nuts!" Lessar snapped her fingers. "Maybe a little milk will wake him up..."

Misaka rapped her on the back of her head. "Dummy! We've got to find that old man, pronto! Before he does this to other girls and turns them into contagious horny, big breasted nymphos who could really go for having Touma's cock inside of them just -"


She slapped her hands over her mouth, but to be perfectly honest even Kuroko was kind of nodding along with that. Pussy, dick... Sounded really nice all of a sudden.

"That could be a problem," Index observed. "It's been quite some time now, and he was fast enough to dodge your lightning earlier. He could be anywhere by now!"

"That's true enough, but we can't give up that easily!" Misaka yelled. "Guh! We've just got to use our contacts, spread out and maybe we'll catch wind of him before he hurts someone else."

"Oh, I'd never hurt a pretty lady..."

The four girls all stared at Happosai, who was sitting on a street lamp all innocent and coy. Then, as one, all four girls immediately went into hot pursuit of this cackling little goblin, leaving Touma in the alley with nothing to do but lie there unconscious and having really... Pillowy dreams.

Now resuming our chase in progress.

1. Index finishes explaining all of this to Ranma, and the chase is on!
2. Meanwhile, Nabiki is feeling unduly horny.
3. Shampoo and Yami try to fight off their arousal.
4. Konatsu laments his failure and tries to make up for it.
5. Something else
