One day, a very strange thing happened to Naruto Uzumaki. It was an event that would change the course of his entire life, and indeed the lives of all those around him.

He was eleven and a half when he found the stone.

Still a student of the ninja academy, having failed his graduation exam twice, the mischievous young blond had been walking home from class when a certain incident forced him to take a detour down a dark alley.

This was nothing particularly memorable in and of itself, with Naruto being something of a magnet for trouble and often having to take more circuitous routes in order to avoid the irritated victims of his pranks. But on this day, in this alley, Naruto found himself stumbling over a strange, inexplicably glowing rock.

Even years later, after all was said and done, nobody could really say for sure where it had come from. Some suggested it was from outer space, others proposed that it was a fragment of demonic power, yet others insisted it was a gift from heaven, and a few others theorized that it was the manifestation of some obscure, latent kekkei genkai.

Nobody could really say for sure if it had even been a rock at all. The only person to see the object was Naruto himself, and even he would admit that his memory of the day was largely a blur.

The stone, or whatever it was, tripped Naruto in that alley. His foot hit it, causing a disruption in his gait. He crashed face first into the dirt, scraping his forehead and banging his nose.

Naruto swore, clutching his schnozz and shaking his head.

"Dabbit, dat hurt!" he hissed.

Turning around, Naruto searched the ground for what had tripped him.

It was – as far as he could recall after the fact – small, purple, and vaguely round-ish. It was glowing, dimly at first, and then seeming to get brighter the longer Naruto looked at it. Something about the color fascinated him, the light triggering the flip of a switch somewhere in the back of his brain.

Curious, Naruto reached out to grab the unidentified rock-like object.

And that was subsequently the last anyone ever saw of it. Naruto lost consciousness the moment his fingertips brushed the stone, fainting away dead on the spot. When he woke up, an undetermined length of time later, the object was nowhere to be found.

But Naruto was in no state to ponder the disappearance of that offending obstacle. He glanced up at the sky, and realized something of dire importance.

"Oh, crap! I am so late for dinner!" he yelped, his cry perfectly masculine and not at all girly. "Mom is gonna kill me!"

And so Naruto raced home, as of yet unaware of the newfound power slumbering deep within him.

... ... ... ... ...

"YOU'RE LATE, BRO!"

This shout was Naruto's only warning before a yellow and black ballistic missile impacted with his abdomen. He was tackled to the ground the instant he crossed the threshold, pinned beneath the form of his twin.

"Gah! G-Get offa me, sis...!" Naruto yelped, blushing as he felt his sister's bottom plop down hard on his crotch. "Ack! No fair, I couldn't help it!" he protested, but to no avail.

Naruko Uzumaki stuck her tongue out at her brother, and crossed her arms of her chest. She was Naruto's fraternal twin, and also the bane of his domestic existence. The girl had absolutely no sense of shame, and was always barging in on him no matter what he was doing.

He couldn't even begin to count how many times they had seen one another naked, and with the Birds and the Bees hanging over his head, it was very hard for Naruto to endure it.

She was cute, to be sure, looking generally like himself, except obviously female. She wore her blonde hair in twin-tails, and dressed in the same kinds of clothes as her brother. But where Naruto had the figure of a boy, she had... well, also a rather boyish figure, if you had to ask Naruto. Of course, saying as much to Naruko's face would earn you the beating of a lifetime.

Naruko had her mother's temper, and she was maybe the only person in the Leaf who could be called even more rambunctious than Naruto. She also enjoyed wrestling with her twin brother – perhaps even a little too much to be appropriate, although Naruto would never admit this out loud.

"You're late, bro," Naruko repeated, wrapping her legs around Naruto's head and smushing her butt even harder down on his groin. "Mom was about ready to hunt you down and string you up!" She smirked. "Heehee, if it weren't for me, who knows what she would've done to you?"

Naruto gulped, paling.

His mother, Kushina, was loving and gentle most of the time, but she had a temper even Old Man Hokage feared. While she said she hadn't been much of a ninja while still on duty, she was honestly crazy strong.

The only thing scarier than the thought of what kind of punishment his mother might have meted out of his tardiness... was the silent anxiety over what kind of favor Naruko would demand from her twin in exchange for averting their mom's wrath.

"What do you want?" Naruto asked, wanting to cut straight to the chase. If his sister had indeed pacified their mom, then she had seriously saved his bacon. He couldn't deny her that.

Naruko smirked down at her brother. Teasingly, she scooted her bum side to side a little bit. It took a great deal of willpower on Naruto's part to keep... certain parts... from reacting to this. She stretched her arms over her head, theatrically rolling her shoulders.

"Weeeeell, I have been pretty sore today..." she said, putting on a very compelling act of innocence. But the glint in her eyes betrayed Naruko's true intentions. "So how about you rub my shoulders, bro?"

Naruto sighed, but didn't protest. She could have asked for worse.

She could have asked for MUCH worse.

"Fine, alright," he said. "Just... get off me, okay? I'll be there in a few minutes. I need a bath."

Naruko laughed.

"Lucky you, bro!" she said. "Because I was just about to take one." She winked teasingly. "How long has it been since the last time we took a bath together? It would be just like old times. You can even rub my shoulders while we do it!"

It was lucky for Naruto that his sister chose then to get up, because the mental images provoked by the girl's statement were enough to break through the mental stranglehold he had on his hormones.

His sister wouldn't have ever let him live it down if he got a boner while she was sitting on him.

... ... ... ... ...

Of the bath itself, Naruto would have little recollection afterward. It had been awkward at the time, he could recall, although in hindsight it was a very pleasant memory, what little he remembered of it.

He and his sister bathed together for the first time in years, and as she requested he rubbed her back. Past that point, Naruto could only remember a jumble of emotions, hot skin, steam, and forbidden passion.

Probably, he and Naruko wound up having sex in the bath.

And probably, it is said, because Naruto could scarce remember it afterward...

...and Naruko would not see the point in trying to.

... ... ... ... ...

It was strange. Warm all over. Naruko felt a fuzzy warmth in her belly.

Water dripped from her naked frame, her skin tingling, her body aching sublimely. The floor darkened with the blotches of wet droplets falling from her body as Naruko made her way to her room. Her bare feet left water tracks on the hallway floor.

Naruko knew her mom would be annoyed if she saw the water her daughter was tracking everywhere, but the girl couldn't bring herself to care. She felt so nice, with a certain pleasant looseness to her insides, a warm buzz tickling at the back of her mind.

She hummed, letting herself collapse face-first, naked, and soaking wet onto her bed. Water seeped from her skin, dousing her covers. Her bed grew wet, uncomfortably cool and damp, the longer Naruko lay there. She knew it would be nearly impossible to fall asleep if she let her bed get this wet, but the girl just couldn't bring herself to care.

She didn't want to care about it. She didn't see a point in getting so worked up over such little, insignificant things. Not when such wonderful sensations were going through her body.

There was an itchiness in her tailbone, a dull ache in her abdomen. Naruko's ears were tingly, and she felt two more itchy spots on either side of her head, buried beneath her hair. Her muscles burned, the satisfying pangs of a good workout. Her pussy ached, a faint recollection of forbidden passions shared with her brother.

Naruko felt a blush creep into her cheeks as she thought about Naruto. She wiggled her hips weakly, mewling to herself.

"Oh, bro..." she purred, sighing wistfully. "That felt so good... Why can't we do it again?" she whined, pouting at the head of her bead. "Just because he's my brother? That doesn't seem fair."

This wasn't the first time Naruto's twin sister had entertained such thoughts, but it was the first time she had ever felt so firmly about them. There seemed to be a sense of vindication and rightness the more she contemplated it.

And the more she thought about it, the less she felt the need to think about it.

"Naruto's my brother... I wanna do that with him again. It felt good to do it with him. I want to feel good again. I want to keep feeling good like that. I want to feel that good all the time. I want to do those things with Naruto... and keep doing them, over and over..." Naruko whispered, reaffirming her own perverse desires with every sentence.

She moaned, arching her back. Her body ached so wonderfully. And hadn't her bed been bigger than this?

"I love my brother," Naruko whispered, moaning. "I love him. I want to feel good. He makes me feel good. I love to feel good. I love my brother." She bucked her hips with a gasp, feeling a shiver, a shudder, a clenching and bursting and gushing and bliss.

Naruko brought hands up to her breasts. They were larger than she remembered, all four of them. Much larger.

Absently, she wondered if this wasn't twice as many boobs as she used to have. But this seemed such a minor, unimportant detail to Naruko, so she gave it no further contemplation. Her tail flicked happily with this assessment, long pointed ears sticking out sideways from her head. Dull, short horns dug into her pillow.

Naruko's bed continued to get wetter, but not from water. Her nipples were huge and puffy, erect. Her tits were enormous, so large and so sensitive that she had to roll over onto her side to keep from going mad with pleasure.

"I love my brother," Naruko moaned, looking down at her four huge breasts, stacked two over two. "He makes me feel good all the time. I feel so good, it doesn't stop. I want bro to feel this good, too. I love him. I want him to feel good."

Naruko came, milk spurting violently from her nipples, nectar flooding in a torrent from her distended cunt.

She lowed like a cow, panting and sweaty.

"...I love my master..." she whispered, before falling contentedly into a deep, dreamless sleep.

... ... ... ... ...

The next morning, Naruto woke up at his usual time – two and a half hours before class was set to begin. If he'd had a choice in the matter, Naruto would have preferred sleeping in until the last minute, but his mom was a firm believer in early birds catching the worms.

So, drowsy and bleary, feeling vaguely disoriented and muddled, Naruto got up out of his bed. Turning off his alarm clock, he grabbed a fresh change of clothes, then opened his door. Still dressed in his pajamas, and yawning, Naruto stepped out of his bedroom and turned down the hall.

His ears were still ringing from the alarm clock's incessant beeping when he reached the bathroom door, so Naruto could perhaps be excused for not noticing the sound of the shower running. And when he opened the door, the steam blasted him right in the face, momentarily blinding the blond, who stumbled over the threshold with a hissed curse.

Blinking his eyes, face reddened from the humidity in the bathroom, Naruto could also, perhaps, be excused for not seeing his mom's clothes on the floor. His foot snagged in her skirt, got tangled in her blouse, and tripped Naruto up, sending him careening straight into the shower.

Hot water sprayed Naruto's back, soaking his pajamas. He fell, his face crashing into something soft and warm, distinctly cozy. His arms wrapped around a warm body, hands clinging for dear life onto a pair of curiously firm, round globes.

He inhaled, straining to keep from falling the rest of the way to the shower floor. Whatever his nose was buried in, it smelled very nice.

His feet slipped on the wet floor, Naruto practically kicking as he tried to maintain his precarious balance. His face pressed itself a little deeper into whatever it was unintentionally nuzzling, his hands desperately squeezing the firm round orbs, fingers digging in deep in fear of losing grip.

Faintly, Naruto felt a slight tingling in his palms. A warm buzz spread through his chest, and he had a brief feeling of deja vu.

Did something like this happen last night?

Naruto could not rightly remember. Partly because he didn't have the time to think any further on the matter.

Largely because a hard, angry fist found its way to his skull right around then.

"NARUTO!"

Kushina was generally a very nice and pleasant woman, so long as you didn't get on her bad side. She honestly did love both of her children equally, and she showed it well and often enough that they never truly doubted it.

But she was also a strict disciplinarian, and truly fearsome when angered. And no matter how good it may or may not have felt to have her handsome young son crash face-first into her groin and start squeezing her ass, Kushina still had enough sense to know that:

1.) This was inappropriate.

2.) She probably shouldn't encourage it.

So the feisty, beautiful redhead smacked her son upside the head and ordered him to go wake up his sister. Naruto, after taking a moment to fearfully extricate himself from his mom's nether regions, promptly turned tail and left to do exactly that.

Kushina blushed, trying hard to ignore that pleasantly warm sensation in her buttocks.

"That boy..." she sighed.

... ... ... ... ...

Naruko was in a pleasant haze, drifting on clouds of blissful warmth and softness, when she heard a sound. Her ears perked up, and her tail flicked excitedly. Her nose twitched, sniffing and smelling something familiar.

Something she loved.

Naruko's eyes snapped open. Light streamed in from her bedroom window. Her feet dangled from the foot of her bed. The covers were crusty, damp and musty beneath her body, but she didn't care about that.

She sat up eagerly, an innocently gleeful smile on her face. There was only one thought in her mind as her sapphire blue eyes met the identical shade and hue of her brother's.

Master is here.

Naruko stared happily into Naruto's eyes, looking down at her brother. She shivered, feeling a jolt of excitement race up her spine. Her lips went dry, but her pussy began to grow moist. All four of her nipples stood up, puffy and erect, glistening with a moist white.

She wiggled wide, childbearing hips, setting large and supple buttocks to ripple and shake. Her breasts jiggled as she moved, and she stared warmly, unflinchingly at her twin brother.

She giggled.

"Mmmm❤" Naruko cooed, smiling a little wider and happily spreading her legs. She felt the ache in her belly, an unquenchable fire in her loins.

Her pussy was soaking wet. She felt empty without her brother's dick inside of her, and seeing him so close only made her want it even more.

It felt so good last night. He made her feel so wonderful.

She wanted to feel more of that, and she wanted to make him feel good in return. She felt her body quiver as she shifted on the bed, this new, wonderful shape and figure that felt so nice, and so beautiful, and confident.

She felt sure that this body was given to her by her brother. She had such big breasts now, four wonderful boobs like even their mom didn't have, and she was tall, taller than she had ever been in her life. She felt strong and happy, confident and content.

It was marvelous.

Naruko spread her legs, smiling and groaning happily.

Naruto stared at her. He was red as a beet, slack-jawed and wide-eyed. Disbelieving.

"Wh...what the hell...?" he muttered uncomprehendingly.

Naruko mooed.
