Sasuke trekked through the dense forest, his sharingan eyes scanning the surroundings for any signs of the legendary Wishing Stone that Orochimaru had sent him to find. The snake sannin had learned of its existence from an ancient scroll and hoped to use its reality-warping powers for his own nefarious purposes.
As Sasuke leapt from branch to branch, he couldn't help but feel a twinge of unease. The idea of an all-powerful wishing stone seemed almost too good to be true. Still, he couldn't afford to disappoint Orochimaru after the Sannin had taken him under his wing to help him gain strength to defeat Itachi.
Just then, a glimmer of light caught Sasuke's eye amidst the foliage up ahead. He landed on the forest floor and cautiously approached what appeared to be a small clearing. There, resting atop a moss-covered boulder, was a fist-sized gemstone radiating a soft bluish glow.
"That must be it," Sasuke muttered to himself. He reached out to grab the stone, but suddenly sensed a presence behind him. He whirled around, kunai drawn, to find none other than Naruto standing there with a sheepish grin.
"Hey Sasuke! Fancy meeting you out here in the middle of nowhere," the blonde ninja said with his trademark annoying cheerfulness.
Sasuke scowled. "Dobe. What are you doing here?"
"Oh you know, just taking a stroll through the forest on a beautiful day!" Naruto replied breezily. His eyes then fell on the glowing gemstone. "Whoa, what's that thing?"
"None of your business," Sasuke snapped, scooping up the stone protectively. "Now get lost before I make you."
But Naruto was already sidling up next to him to get a better look. "No way, is that like...a magical wishing stone or something?"
Sasuke didn't respond, but the surprise must have registered on his face.
"No way, it is!" Naruto exclaimed gleefully. "A real life genie stone! Oh man, just think of all the awesome wishes I could make. Like having all the ramen in the world or-"
"Would you be serious for once?" Sasuke cut him off in exasperation. "This is powerful ancient magic, not some childish game."
Naruto rolled his eyes. "Oh lighten up, Sasuke. When are you gonna learn to have a little fun?" He snatched the stone out of the Uchiha's hand. "Here, I'll start us off with an easy one!"
Sasuke watched in horror as Naruto closed his eyes, clutching the Wishing Stone tightly as he made his foolish request.
"I wish Sasuke was a totally hawt girl with no ninja skills who talked like a little kid and said embarrassing stuff all the time!"
There was a blinding flash of blue light, forcing Sasuke to squeeze his eyes shut. When he opened them again, he felt...different somehow. Smaller. Lighter. It took him a moment to fully comprehend the changes to his body, but one look down at his new feminine physique and ample chest was enough to confirm it.
"Gwah!!" Sasuke cried out in a mortifyingly cute, high-pitched voice. "W-What did you do to me, you baka Nawuto??"
Naruto's jaw dropped as he stared at the dark-haired, ruby-lipped beauty before him who could now barely meet his eye level. "S-Sasuke? Is that you?"
"No, it's the Hogake!" the newly feminized Sasuke shouted, unable to properly pronounce her R's while pouting and furrowing her delicate brows adorably. "Of course it's me, you dummy-dum! Change me back wight now!"
Naruto was in utter disbelief, but he couldn't deny the appeal of this softer, cuter version of his former rival. In fact, he found himself struggling not to outright gawk at her.
"Ah heh heh, wow Sasuke, you clean up pretty nice as a girl! Are those...uh...honkers' for real?"
"Don't look at me wike that, you pwevewt!" Sasuke shrieked, trying and failing to sound threatening as she covered her large chest instinctively. "J-Just make anothew wish to change me back!"
"Aw, but you're so adorable this way!" Naruto chuckled, reaching out to pinch her cherry-red cheeks. "I could just eat you up!"
Sasuke swatted his hand away grumpily. "Quit twopping me! And give me that stupid wishing shtone!"
She made a grab for the gemstone, but Naruto held it up over his head, easily taking advantage of his new height advantage.
"Nu-uh, not until you ask me nicely, little lady!" he teased.
"Mou, give it!" Sasuke whined, jumping up and down in vain as Naruto continued laughing and dangling the stone tauntingly.
"Say the magic words!"
Sasuke huffed, sending her silky raven tresses bouncing cutely. "Pwease Nawuto, may I pwetty pwetty pwease have the stupid wishing shtone?"
"Since you asked so nicely..." Naruto handed it over, only to let out a yelp as Sasuke promptly beaned him on the forehead with it.
"Hmph, sewves you wight!" she snapped before clutching the gemstone tightly. "Okay, I wish I was back to being a big stwong...errrr..."mawee" guy again! No, wait! A man! A man!"
Once again, the Wishing Stone pulsed with blinding blue energy. But when the light faded, Sasuke was still very much trapped in her adorably girly body.
"W-Why didn't it work??" she cried, cradling her larger than average bust in distress. Her enhanced feminine assets jiggled hypnotically as she trembled in shock. "Why am I shtill wike this??"
"Pfft, beats me!" Naruto hooted, finding the whole thing terribly amusing despite the bump forming on his head. "Guess you're stuck as a sweetie-pie cupcake babe for a while!"
"No no no!" Sasuke shouted, stomping her little feet in frustration and eliciting a soft pout from her perpetually pursed lips. "I don't wanna be cute and pwetty, I wanna be big and stwong and sumo wrestswer mawee!"
"S-Sumo wrestler manly?" Naruto barely managed through his hysterical laughter. He had to wipe away actual tears from his eyes as the mental image of Sasuke as some ultra-macho behemoth overwhelmed him. "Oh wow, that's just priceless!"
Sasuke felt her cheeks burning as humiliation set in, knowing her tomboyish tough girl schtick was only drawing more amusement and patronizing affection from the jinchuriki.
"Ugh, I hate you!" she spat, though with her honeyed voice and pouty mannerisms it hardly sounded threatening at all. "Nevew speak to me again, baka baka Nawuto!"
With that, the effeminate Uchiha spun around in a huff, her adorably oversized ninja skirt flaring outward as she began to flounce away with exaggerated arm motions. The look was only amplified by her wide, swaying hips that caused her sizable rump to bounce and jiggle with every indignant stomp.
"Aww, where're ya goin', buttercup?" Naruto called after her in a mockingly sweet tone. "You know you're just gonna get all turned around in that big scawwy forest!"
"I can take cawre of mysewf!" Sasuke shouted over her shoulder, blissfully unaware of how irresistibly pouty she looked as she planted her delicate hands on her hips. "I don't need some dumb boy to pwotect me!"
Naruto rolled his eyes, knowing he couldn't pass up a chance to push her cute new buttons.
"Suuuure you don't! But what if a big bad monster jumped out and tried to nibble on your precious little toesies?"
