Story: Titnosis 1/2: Kasumi Gets

Based on a suggestion in the comments. Continued from here. 
It was amazing the things that would be uncovered after a good cleanout. Kasumi didn't quite have the time to do one all that often, but every time she did a veritable treasure trove emerged. Mother's old recipe book, martial arts scrolls that Father thought long lost (which Ranma and Akane would squabble over being the first to read), photo albums, loose change (which only Nabiki got excited about, let's be fair) and who could ever forget Happosai's various secret stashes of porn and other things that he'd gathered over the years?

Kasumi couldn't. And not for lack of trying. Believe her on that, not for lack of trying.

Still, today had been a productive enough gutting out, which was all that really mattered. She happily wiped the sweat from her brow, casting the very image of the adorable housewife. "Let's see…" she thought out loud, checking her wristwatch. "I have just about enough time to look through one more box, then I simply must clean up and make dinner."

She scanned over the boxes littering the attic and sighed. It would take years to empty it, by which time more assorted junk would no doubt find its way back up. Odd thing. The Saotomes didn't seem to be contributing all that much to it. Almost certainly a side effect of their apparently constant moving around. Keep as few possessions as you need at any given time. An attitude Kasumi could certainly respect. It was quite funny, actually. One time Kasumi had walked in on Ranma scrubbing a floor while mumbling to himself about how some people should be more careful with their drinks and not spill it all over the place. Nabiki had found it funny as well, albeit for different reasons that Kasumi probably did - probably something to do with the orange juice she was sipping.

Nabiki really was too naughty for her own good sometimes. One of these days she'd find herself in trouble she couldn't snark or blackmail her way out of, and that worried Kasumi more than she could express.

The first item in question was a blanket, placed on top of the box like a protective layer. Kasumi carefully picked it up and unfurled it in a single motion. "Maybe this could be useful once it's given a good clean?"

Her face froze for a moment in an apparently blissful smile, but inside she was feeling anything but. Oh, dear. Those were some rather gratuitously graphic pornographic images, weren't they? However did those ladies bend that way, and why did the giant tree in the middle decide to eat all their clothes? "Another one of Happosai's hidden surprises," Kasumi sighed. The blanket was bundled up and thrown into the "burn me" pile.

Most people might have seen that and found themselves too afraid to continue on, knowing all too well that journeying into the depths of Happosai's depravity was like diving to an ocean floor. It was impossiblly deep, pitch black and there were things in there worse than any nightmare you ever had that wanted to taste your flesh. Regardless! Kasumi did not believe in leaving a task half finished. She may be afraid. Terrified, in point of fact… But that was the point to bravery. To be afraid and to move on despite it.

Even so, her eyes were firmly squeezed shut as she reached inside the box. That almost made it worse somehow. What would she touch? Panties, probably. The squelch of some sick sex toy he'd never had the chance to use. Whatever she imagined was sure to be worse than reality, and yet in her hand plunged and came into contact with something that probably terrified her worse than any other possibility.

She touched paper.

Kasumi whimpered slightly and pulled it out. Oh dear. Oh my. What had she found now? The discarded notes to the Kama Sutra? Some crude sketch the ancient pervert had made of that one time he peeked in the Joketsuzoku bathing house? She let an eye creak open, inch by terrified inch, and she saw a scroll that she unfurled with a slight wince.

"Rush of the Rampaging Rhino," Kasumi said. "This looks like… a martial arts technique."

Two voices cooed, one over each of her shoulders. Knowing what she would see when she turned around, Kasumi did so and smiled at her little sister and future brother-in-law, who were both looking at her with expectant, pleading eyes and slight bounces in their feet.

Neither had been there five seconds previously.

"Can I have it, Kasumi?" Akane asked. "Please, please, please?"

"No way, tomboy, you'll just mess it up!" Ranma replied. "I'm way more suited to figuring out this scroll!"

"Don't listen to him! I know I can make it work if only I have the chance!" Akane sniffed, and sharply turned her head away from Ranma. "Knowing him, he'll just use it to show off and pick up girls!"

The bickering and arguing began with earnest then. "Uncute!" "Jerk!" "Clumsy!" "Pervert!" and so on, until the two of them had probably even forgotten why they were arguing in the first place. Kasumi shook her head and reached into the box, pulled out another scroll and unfurled it.

"Lunar Wolf Dance!" she read, but to herself rather than out loud. Another martial arts scroll was exactly what she needed, and so she took both, gave them a little shuffle and randomly passed one each to Ranma and Akane, which rather interrupted their ongoing argument. "Here," she said, with each of them looking up at her rather sheepishly. "One scroll each. Now, go off to the training hall and play while I finish up here." A reassuring pat on their heads, and the two of them slunk off side by side.

"You started it," Ranma whispered.

"Did not!" Akane hushed back, and then they were both gone.

Oh, young love. The two of them were so adorable together! If only they could see it, they would certainly agree. With a playful giggle, Kasumi turned her attention back to the box. Well! This wasn't quite as bad as she had first surmised! In fact, if all of these scrolls were martial arts techniques Happosai had discovered and forgotten about over his long years of hoarding, this would be Christmas come early for the two young martial artists! They did so love showing each other up. Almost as much as they enjoyed spending time in each other's company while insisting that they didn't and anyone that said differently was a filthy, filthy liar.

Except… underneath all of the scrolls there was something else. Kasumi could see it now, the corner was exposed by the removal of those two scrolls. She took them all out, gave them a cursory glance - they varied between martial arts skills and pressure point descriptions that Doctor Tofu may find interesting - and carefully extracted a book.

Sadly she could not make out the book's title beyond "Secrets of -" something or other. Another book on martial arts? Or perhaps further details on pressure points? Or erotica? Sadly there was but one way to find out, and that involved opening the book.

"Do you have no control over your life? Do you feel that life is unfair, that people ignore what you have to say? Do you feel unattractive, unappealing, or simply want a better boyfriend than your usual bunch? Look no further! Follow Dr Janet McNutt’s procedures, and you too can have as much control over your life as you could ever dream! Through the art of titnosis, enhance your bustline and use it to brainwash a whole other sort of boob."

Erotica it was. Kasumi shook her head and sat down. Such inappropriate material to have simply lying around! But, still. She should at least finish the introduction, just in case her first impression was incorrect. Far too often that had been the case. For example, the first time she'd met the Saotomes one had been a panda and the other a girl. First impressions were not nearly as reliable as some may think.

"What is more, my thorough studies of breasts have unveiled what I believe to be a mere fraction of their full potential. Tits have power as yet untapped and it is my fervent hope, dear reader, that you will be able to continue my experiments and demonstrate the awe-inspiring power of tits! Change minds, alter bodies, anything is possible under the power of titnosis! Sadly, for far too many that may be willing to help out they may not be fully able to do so due to lack of titflesh. Ah, but this is no problem either! This book has a specific enchantment upon it that will enable anyone reading the prologue to enhance their own bust to the appropriate size. Don’t worry about your clothes! They will change to accommodate you. If you wish to help the progression of tit power, then merely speak aloud the words Boobicus Maximus."

The book slipped from her hands and thudded against the floor. Kasumi's eyes had gone wide, then rolled up as she collapsed to the floor. Her entire body began to shudder uncontrollably and a strange heat was spreading throughout her very being. A gasp escaped her throat and her hips bucked slightly, then again with more intensity, then again with enough force to shatter steel.

Kasumi clutched at the ground and writhed in unexpected pleasure. She could feel it. The promised transformation. Her breasts were tingling, expanding, growing. Bigger, bigger, biggest! She bit her bottom lip and somehow managed to catch her breath for long enough to say one simple sentence.

"I shouldn't have read that out loud," she whispered, then allowed herself a content sigh as her transformation finished.
