Cameron paused as he looked at what he just scribbled down in his new journal. He leaned back in his office chair at the desk, eyes spying around the closet he had to call a room. He placed a pen between his thin lips, humming aloud “Do you usually put the location in a diary? Naw.” His pen stroke across the top.

5th of May, 2019

Location: My house

To whomever it concerns, this is my plea to any sanity left in this crazy world. This diary will act both as an outlet to keep me sane, but also for documentation of what is happening around me. And what is happening around me needs documentation.

All I should be doing right now is living like any other twenty-year old should: living life to the fullest, starting my professional life, and maybe finally losing that annoying virginity which still haunts me. But no, this is impossible. Despite my normal body and personality, and both my parents being as exciting as soup crackers, I have one big problem.

*BANG*

His wall shook as something big hit the other side, rattling his little-league sports trophies like a coming stampede. It was most likely accidentally but it grated him all the same. He grinded his teeth before putting his pen back on the paper with vigour.

My sister Lily has been the centre of attention since she was born, and before, it was perfectly reasonable. She had always been a sickly ch1ld from day one, and once she became a teenager, everyday became a struggle. Everyone in our small family put in the time to help her to live a normal life, but we were running out of ideas on how to save her increasingly diminishing health. I still strongly remember how feeble and thin she looked in those days .

*BANG*

But then things improved in the strangest way. Our religious grandma had given us a moss-covered stone from the ‘old country’ and asked us to put it in a water jug. It was strange but we gave this water to Lily every night before she went to bed. Everyone was skeptical, but more shockingly Lily started getting better. We’re still not sure if it was actually the rock, maybe the new medication was finally kicking in, but you couldn’t argue with the results. Within a month, Lily passed for a normal, albeit underweight, teen.

And that’s probably where the story should have ended.

*BANG*

Cameron groaned at his ceiling, pounding his fist against the wall. “Lily! Stop it!”

Of course, there was always a chance for a relapse, so the medicine/rock-water regime continued. During all that time, Lily has been getting healthier and healthier, or more accurately stated, better and better. Puberty long denied to her struck with a seeming vengeance, smiting every inch of her with blossoming womanhood. This is something which I would have been happy with earlier, but the circumstances are oddly… suspect.

For example (and I hate talking about this but it’s such an obvious example), my sister seemed to be developing perfectly fine (you know, up top) but then she came home one day, complaining about some girls making fun of her bra size in gym class. Since that day? Her breasts have been ballooning!

Now this could just be a funny story about karma, but then the same thing happened with her height after her run in with the woman’s basketball team, her hair and face after the rich prep k1ds, et cetera. Hell, I think she was just upset about some Instagram photos when her legs and butt grew.

And then-

*Boom*

Another distraction rattled him, this time a different clatter, shaking the floor like San Andreas. He stood up with tense shoulders and tightened fists, knuckles white, fingers grinding. Social anxiety about this issue aside, his sister had to learn that she wasn’t the only person in this house, no matter how much mom and dad ignore it. Last time he complained about things, of course, they just gave her his room, but he couldn’t simply sit there listening. He needed to act and regain control.

This sense of empowerment quickly diminished though, once he was faced with what was causing the racket.

Using a diary to describe the current status of his sister’s… rear keister, to safely state it, was a real difficulty as it really was beyond conventional comprehension. Imagine the nicest butt you’d seen in a picture online, even the air-brushed ones that ladies can spend hours editing. Think about those shapely heart cheeks which jiggle symmetrically in anything, and expand them two sizes past the biggest asses you’d seen. It was both a behind of pure expansive muscle which were frankly of livestock-scale, which gave it that flawless and desired bubble women work a lifetime for, but also having a thin layer of smooth fat, so every little gesture would cause a stone-skipping shimmer in the skin, all right before rippling back into smooth tanned skin that literally sparkles at any angle.

And he didn’t think she had done a single squat in her life.

This was the behind, the one he’d probably accuse of being photo-morphed if it wasn’t teasing him all the time, which was currently shaking right outside his doorway. Mashing up and down against the floor, each flop creating a deep-bass, his sister was doing stretches in a tiny pair of baby-blue panties which disappeared between those twin tanned orbital moons. And stretch she did with legs like those, those thick but long thighs somehow keeping her body proportionate despite such an overdeveloped and powerful badonka-donk which now shook the house.

Crossing his legs, Cameron deepened his voice best he can, despite the urge to squeak at the sight. “Lily?!” His arms waved to the bouncing behind, “Do you mind, like, not doing that?!”

“Bro?” That flawless blonde mane finally swayed around, glittering as its mid-shoulder length flipped over to the opposite shoulder. Her face looked honestly surprised he had come out of his own room, the girl still in a world of blissful ignorance about the world around her. “What’re you doing here? Do you need to get by?”

He was instantly at a loss of words upon seeing her face. His sister was still in this walking farcical monument to sexuality. Those cute wide eyes with glimmering blue pupils and a button nose was the sister he knew! But now they had been somehow enhanced to be cuter. Blue eyes now deep oceans which reflected like a mirror, and her nose got even button-ier.

Most girls would be happy with such natural beautiful features, but it was not enough for her unstoppable puberty. Her cheeks became more angular, her ears somehow shrunk to perfect proportions to her nose. Her eyebrows, once normal, now had a natural dark sharpness to them, an effect which most women had to have weekly visits for. But attention usually wasn’t drawn here when addressing that angel face, as big, puffy, pink and soft lips were in a permanent pout, a natural gloss which made them always seemed soaked and even hypnotizing.

Lily shrugged and went back to her stretching, pull one leg up over her head so her knees touched her shoulder. It took her brother a couple more of her grunts to regain composure. “Lily, w-why are you stretching in the halls?” Between his legs became like a vice as he crossed tighter.

“I can’t stretch properly in my room now!” She purposely pouted this time, those lips curling to almost reach her cute little nose and creating a fire-storm of dirty thoughts in Cameron’s head. “Every time I try to put my leg up, I hit a wall. My legs have grown too much!” She turned around and nearly bounced to her feet, meaning Cameron, in order to see his sister, would have to look up.

And up.

And up.

And up.

It wasn’t enough for her to be as tall as the basketball team, or even a bit taller. She had to utter dwarf those already tall ladies with a height which put her in the record books. She might have not have been literally the tallest woman in the world, but she was easily the tallest still-growing-teen and probably the best proportioned one at that. The doctors had said that as long as she didn’t have any discomfort she was fine, but every month, it seemed as if her legs grew more fine. They remained so firm and thick, and yet, they even had that much desired thigh gap permitted by constantly widening hips.

He was trying to make heads or tails of how tall she would be at the moment, but something blocked his view. Lily leaned forward at her hips to point at her legs with two fingers. The unintended side-effect of course being that her chest was put dead centre of Cameron’s view, the t-shirt fabric rubbing his nose.

His sister had the kind of chest which made it the first feature you’d see when she was coming or going. Even from behind, the outline of two round orbs dominated one’s focus when they were in the room, and he had even seen them cause a couple of car crashes when Lily was merely reading on the front lawn.

Of course, he wasn’t the only brother in the world in the world with a sister with large breasts, and he supposed he could’ve adapted to them better if it wasn’t for one torturous feature. Lily refused to understand that she had outgrown some of her favourite tops, meaning that most of time, she was showing such magnificent underboob that it really should have been criminal. This, combined with her confusion why anyone would need a bra with tits that perky, meant he was usually ducking not to get his eyes poked out by nipples protruding against the tight fabric every time she was around.

“See?” She patted her thighs and pressed his head further between her twins. “I told you they were long.” All her heard was muffled tremors though, as he was faced with the farcically warped words ‘Wonder Brat’ stretched over this mountain range of tanned flesh.

When she pulled back, Cameron’s face was like a beet, having almost forgotten how to breath momentarily as his brain cells took an early retirement. He shook his head and gasped for air, “I-I couldn’t see how long they were, because-”

”Oh!” She gasped with a hand over her open mouth, her nails looking the same they had two years ago, the one and only manicure she had ever needed since getting on this puberty wild ride. “Sorry Cammy! Sometimes I forget how much booby I have now!”

He hadn’t been bothered by being called that diminutive before when she was his tiny sister, but now that she was so much taller, it made him feel almost like her little pet. He stuttered as his face got somehow redder, “J-just do your stupid stretches somewhere else, okay!?” His fists shook, already cursing how easily he had lost his temper, but this was a typical case as of late.

“Ooookay, Cammy!” She gave a dopey smile which exposed each pearly teeth in their shining glory. “But first, I wanna show you what I learned yesterday!” She bounced her oversized butt back to the ground, quaking the foundation again, and stretched those miles of legs out before pulling them up. Before Cameron could even properly react, she had both those thick, throbbing calves behind her head, her palms lifting the rest of her body as she did a perverse walk which pushed those big tits to her chin. “Cool huh? I found the more advanced stuff online and it turns out my body is, like, super flexible!” She then lifted one hand up to carry her entire body upon one fingernail, posture stiff as steel. “Oh, Cool! Count how long I can do this! One. Two. Three. Fou-”

She had done her first yoga class yesterday, but she was already licking her elbow like a pro. He slammed the door between him and the hall, knowing that using reason would likely melt his brain. Cameron sat his butt back into the office chair and rubbed his head.

Yoga had proven to be just like violin, painting and juggling. After just one short class, she had the teacher crying at her instant brilliance. He had heard of natural talent, but any attempt to convince his parents of perhaps something more ridiculous going on and he was quickly dismissed. After all, everything happening to her was merely a gift from God in the eyes of the community, and people don’t want to lose their little miracle. He sighed and went back to the page.

And then

I have my own theories on what the causes of such rapid transformations are, but I want to make a few trips to the library after coming up blank from my searches on Wikipedia. What are the origins of this stone? I’m forbidden to touch it, but what if it isn’t actually some religious mumbo-jumbo and is something much more dangerous? And if it’s something else, then-

“Oh Cammmmy?” A sing song tone in perfect tune hummed through the grate which linked their room, Lily probably pressing her mouth against it for maximum annoyance. “I need your help with something!”

Cameron grumbled a bit, rattling his fists into the air “Lily I-”

“Oh but big brother,” her voice did that turn which he hated, the impossible tone she could do where it was half a seductive growl and half innocent plea, “you simply must help me. Please help your little sister with her big problem.”

He shuddered, two shots of electricity racing through his body, one firing up his spine, and the other one firing in a place best left unmentioned. Futilely, he threw his pen in the corner and rubbed his temples. He looked at the clock, feeling he had been resisting his sister’s charm for minutes when it actually had only been five seconds.

“Oh my big bro-”

“I’m coming!” He called back too eagerly to her, adjusting himself and slipping into the next room to see something deeply troubling for the poor boy.
