Naruto: I am Uchiha Shirou

Under the moonlit night.

Inside the house, 'Uchiha Mikoto' trembled, holding the body before her tightly. As Shirou lightly reached out to touch her, he couldn't help but smile at her startled, kitten-like reaction.

"Mikoto, you're still just as playful as ever."

After being tackled to the ground, Shirou was momentarily stunned but soon let out a doting smile, chalking it up to Mikoto's playful nature.

"Shirou… if you like… I… I can turn into… Kushina…"

Panting heavily, her trembling voice quivered as she spoke, not even daring to lift her gaze to meet his. Her hesitant tone caused Shirou to smile. He leaned down, whispering teasingly into her ear:

"Mikoto… does this mean I should start calling you Princess Kushina now?"

His drawn-out teasing words echoed, making Mikoto's face flush red. Her eyes glistened with embarrassment, filled with misty tears of shyness.

With a puff of smoke, the transformation was complete. The white smoke dispersed, revealing fiery red hair glimmering with a seductive glow under the moonlight. Long, slender legs clad in black stockings stretched out before him.

"Shirou… I'm wearing what you like…"

Her shy, stammering voice echoed softly. Tonight, she had specifically chosen stockings that covered her toes, unlike her usual style that left them exposed.

"Princess Kushina…"

As the two looked at each other with increasing sincerity, Mikoto—now transformed into Kushina—was even more bashful.

When it came to their personalities, Mikoto was the gentle type, while Kushina was playful and mischievous. The two were poles apart, yet both equally captivating.

As their interaction deepened, Shirou began to feel something was off. Tonight, things seemed unusually vivid. Moreover, Mikoto seemed strangely inexperienced.

"Wait! You're the real Kushina?!"

Shirou exclaimed in shock. This level of realism wasn't just transformation jutsu. Her reactions, her subtle tremors—they were far too genuine.

At this moment, Kushina's shy expression deepened. Despite her embarrassment, she summoned the strength to lift her head, her misty eyes brimming with determination as she spoke in a trembling voice:

"Shirou! From now on, Kushina belongs to you and only you!"

Shirou was stunned. The person before him, who he thought was Mikoto transformed into Kushina, was, in fact, the real Uzumaki Kushina.

Under the moonlight, Kushina's tearful and passionate eyes seemed to regain some clarity. However, in the next moment, tears began to trickle down her cheeks.

Though inexperienced, she was unyielding, like a fearless calf facing a tiger.

"Shirou… I'm about to become a monster… I know this is shameful, but I want you to remember me! Remember me for the rest of your life! I am Uzumaki Kushina!"

Even though her identity was exposed, Kushina's tear-filled eyes were firm with resolve.

In her heart, she questioned whether the person she would become after turning into a monster would still be herself. She wanted to give the untainted version of herself to someone she deemed important—the one person she could entrust with her life.

"Kushina…"

True to her title as a princess, even in her shyness, she still exuded a regal authority. Seeing this bold version of Kushina, felt his heart ache for her even more.

"Kushina, did you forget our secret? We're both little monsters…"

As their breaths grew heavy, even the moonlight seemed shy, retreating behind a cloud.

In the bed.

"You're so beautiful," Shirou murmured, leaning in to place a tender kiss on her lips.

Kushina melted into the kiss, returning it with all the passion she could muster. She felt his hand slide up her thigh, and she gasped as his warm fingers brushed against her bare pussy. She arched her back, pressing herself against him, desperate for more.

"Shirou~," she whimpered, her voice little more than a pleading whisper.

With a low growl, he leaned down again and captured her lips in a fierce kiss. His tongue dove deep, teasing and exploring her mouth as his hand slipped between their bodies to find her clit. She cried out, arching her back off the bed as waves of pleasure washed over her.

Kushina surrendered to the sensations that coursed through her body. His fingers were magic, teasing and tormenting her until she thought she would go mad.

And then he was there, at her entrance. She felt the head of his cock press against her opening, and she gasped in anticipation. He pushed slowly inside, filling her up inch by excruciating inch. She cried out in pain, but it was quickly replaced by an overwhelming sense of pleasure.

"You're so tight," Shirou groaned, his voice thick with lust.

Kushina couldn't speak, couldn't think. All she could do was lie there and let him take her. He began to move, each thrust eliciting a moan or whimper from her. Her hands clutched at the sheets, her body arching to meet his.

As their rhythm built, Kushina felt herself getting closer and closer to the edge. She could feel her orgasm building, the tension coiling tighter and tighter within her. And then Shirou found her sweet spot, his thrusts hitting her just right, sending her spiraling out of control.

Shirou growled, his hips slamming against hers in a punishing rhythm.

"Ahh~ Shirou!"

Kushina cried out, her body shattering beneath him. Waves of intense pleasure washed over her, leaving her breathless and spent. She arched her back, her nails digging into his shoulders as she rode out her orgasm.

"Kushina!"

Shirou continued to pound into her, his hips undulating in a sensual rhythm that sent shivers down her spine. And then, with a low cry, he exploded inside her, his hot cum filling her up in a way that left her feeling both fulfilled and wanting more.

"Shirou! It's my turn now!"

"Hey!"

With a sudden movement, Kushina flipped their positions, haughtily taking charge.

"Don't you like my red hair? Do you prefer it tied up, loose, or maybe Sister Tsunade's twin tails?"

"I want it all…"

"Then one at a time…"

Shirou slid his cock between her plump ass cheeks and pushed forward slowly, feeling her tightness envelop him. Kushina let out a moan as he began to thrust into her from behind, his hips pounding against her ass. He reached around and gripped her pussy lips, teasing her clit as he fucked her hard and fast.

Kushina's twin tails swung back and forth, slapping against her ass with each powerful stroke. Shirou could feel her walls starting to tighten around him, and he knew she was close. With one last thrust, he buried himself to the hilt inside her and held still, feeling her orgasm wash over them both.

As she cried out in ecstasy, he gripped her hair tighter, savoring the feeling of dominance and control.

Shirou panted heavily, gripping two red pigtails in his hands. He spoke softly, "Kushina, I know medical ninjutsu. If you keep pushing yourself like this…"

"The Uzumaki clan doesn't need that; we have incredible recovery abilities. I want more..."

"Kushina, where did you learn all these moves?"

"Sister Mikoto taught me..." Kushina murmured dreamily, her eyes hazy.

In this relentless competition, Kushina revealed her adorable little tiger teeth again, glaring fiercely as she tried to flip their positions and take control. Though unfamiliar with many of the strange techniques, her stubborn nature and ninja flexibility allowed her to quickly adapt.

In this pure contest of physical ability, Kushina's youthful energy was her greatest weapon. Youth meant not only stamina but also a relentless curiosity and eagerness to explore the forbidden.

Shirou silently reflected on how his years of taijutsu training were finally paying off as he overcame one challenge after another.

At dawn, the first rays of sunlight illuminated the aftermath of their battlefield. Shirou smiled victoriously as he surveyed the scene.

...

In the living room.

The miso soup was steamed gently. Kushina, now as meek as a quail, sat with her shoulders hunched, her head lowered in embarrassment. The haughty princess from the previous night had vanished.

It wasn't that she couldn't face Shirou; it was the presence of Mikoto that made the situation unbearably awkward. Beneath the table, her toes curled so tightly in shame that she felt she could dig a hole and hide inside.

"Miso soup, along with some noodles. Kushina, eat plenty to regain your strength. Shirou doesn't usually like sushi, so I didn't prepare any."

Wearing an apron, Mikoto smiled warmly as she brought out a lavish breakfast from the kitchen, making Kushina even more flustered.

"I thought you might need it, so I prepared a spare set of clothes for you."

Mikoto teased lightly, holding out a neatly folded set of clothes. At the moment, Kushina was wearing Shirou's oversized white robe, with a faint glimpse of pale skin showing underneath.

"Thank you, Sister Mikoto…"

Kushina's voice was filled with embarrassment. Meanwhile, Shirou glanced helplessly at Mikoto, his eyes seemingly saying, "Mikoto, you set me up last night."

However, Mikoto's playful gaze in return seemed to say, "You should be thanking me."

The only sound at the table was the clinking of utensils. As Kushina sipped her soup, she asked softly:

"This meal must have taken a while to prepare. Sister Mikoto, when did you get here?"

With a ninja's keen observation, she realized the food was freshly made, not brought in from elsewhere. This raised questions in her mind.

Mikoto gently wiped her mouth and smiled teasingly:

"Well, I arrived before sunrise. But some people have such endless stamina…"

Realizing Mikoto had been listening for who-knows-how-long, Kushina's face turned as red as her hair. Her hazy, embarrassed gaze made her deaf to everything else around her. Mikoto leaned in close, whispering into her ear:

"Kushina, from now on, we'll be true sisters."

Kushina's flushed cheeks practically steamed.

Moments later, under the table, her foot was suddenly lifted, snapping her back to reality. She panicked, blurting out, "Sister Mikoto is still—"

But when she turned around, she realized Mikoto was already gone. Outside, the sound of her footsteps faded into the distance.

Across the table, Shirou held her delicate foot and shook his head. "Mikoto went to buy stockings for you. Otherwise, you'd blow your cover when you go back."

Now realizing Mikoto had left, Kushina transformed from a meek kitten into a fierce, wildcat. Though her face was still flushed with embarrassment, she pretended to be angry.

"Shirou!"

"Stop moving. Look at the marks on your feet from last night's intensity."

Shirou reprimanded her lightly, then placed his palm over the marks, releasing soothing chakra from his medical ninjutsu.

However, during his treatment, Kushina suddenly glared at him with an unyielding expression, baring her fierce little tiger-like teeth. She declared:

"Shirou, I haven't lost yet!"

"Alright, alright, you win, you win. But let's eat first."

Just as Shirou was about to sit down and eat, a sudden disturbance came from under the table. His eyes widened as he looked across at Kushina, who was glaring back at him.

"You're learning this from someone."

"Mikoto told me all about it. She said you like—"

Two soft, delicate feet reached toward his bulged pants. Kushina's mastery of taijutsu was indeed impressive, leaving Shirou utterly stunned.

"Kushina, you're playing with fire!"

Kushina glared at him defiantly, as if to say, I'll do as I please!

But in the next moment, seeing Shirou restrain himself, Kushina suddenly bit her arm. Instantly, her injuries began to visibly heal before his astonished eyes, the marks disappearing as if by magic.

"Hey!"

"Before Sister Mikoto comes back, let's have another round to determine the winner~!"

In an instant, the dining table, living room, and kitchen turned into the battleground for two tireless couples.

As her fiery red hair danced in the air, Kushina Uzumaki's misty, emotion-laden eyes revealed her true feelings.

"Shirou~ I belong to you! Before I become a monster, I'm all yours… my entire body… everything…"

...

By the time Mikoto returned, she was greeted by the sight of an utterly destroyed home.

Not only was the house in shambles, but a faint white stain on the dining table made Mikoto widen her eyes in shock. Then, as if understanding something, her expression shifted.

"So, innocent girls are really more aggressive in bed."

...

At the Senju Clan's residence.

The sun was already high in the sky as Kushina cautiously tiptoed into her home, looking as guilty as a thief.

"Kushina!"

A sudden voice startled Kushina so much that her hair nearly stood on end. She whipped around to see Tsunade standing there. Forcing a calm expression, Kushina patted her chest and feigned nonchalance.

"Sister Tsunade, you scared me!"

Tsunade, however, rolled her eyes and said, "Kushina, why are you sneaking into your own house as if you're a thief?"

Faced with Tsunade's question, Kushina tilted her head back and feigned confidence, retorting, "A thief? How could that be? This is my house. You must be imagining things, Sister Tsunade."

Tsunade gave her a skeptical look, sniffing the air as her frown deepened.

"Kushina, what's that smell?"

"Smell?!"

For a moment, Kushina turned pale with fright. But then she remembered she had taken a bath, so her confidence returned. Taking a deep breath, she replied, "What smell? You must be mistaken, Sister Tsunade."

However, Tsunade, knowing Kushina's personality all too well, immediately sensed something was off. As she caught a faint whiff of something unusual, her eyes flickered with a hint of embarrassment.

Though the scent of body wash was strong, for a ninja of Tsunade's caliber, such a close distance couldn't completely mask a faint, distinct odor.

Looking at the now fully-grown Kushina Uzumaki, Tsunade sighed deeply and spoke calmly:

"Kushina, Jiraiya and Minato came to visit earlier. There's something I need to discuss with you but wash your hands first. We'll talk after lunch."

"Alright! Sure!"

Suppressing the panic in her heart, Kushina nodded quickly and said, "Okay, I'll go wash up now."

As she ascended the stairs, Tsunade let out a long, quiet sigh.

"Kushina's grown up. Having such desires is normal. At least there are no visible injuries on her body. It seems Shirou knows his limits and didn't go too far."

Tsunade considered various possibilities, yet never imagined that Kushina could heal herself so effectively, leaving no traces behind.

Upstairs, as the sound of water echoed, Kushina splashed cold water on her face, trying to cool down her flushed cheeks.

When she raised her head and gazed at herself in the mirror, a rare gentle smile appeared on her face. Stroking her vibrant red hair, she murmured softly:

"At the very least, before I completely become a monster, I'm his."

As for after she became a monster, Kushina's calm smile concealed the fact that she had already made up her mind. At least for now, she had no regrets.

"Sister Mikoto, thank you."

Sealing the Nine-Tails and becoming a Jinchuriki—no matter how much she pretended not to mind, who could honestly say there wasn't the slightest resentment?

In this warped ninja world, tailed beasts represented misfortune and destruction. Even the people closest to her couldn't help but feel some unease.

She had long known the tragic experiences of Jinchuriki in every nation and had mentally prepared herself for the worst.

Looking at her reflection in the mirror, with water droplets sliding down her face, Kushina Uzumaki's sincere smile radiated determination.

"At least I have no regrets. After I become a monster, I'll protect Shirou, Sister Tsunade, Sister Mikoto, and all my loved ones."

"Let's do this!"

Suddenly, Kushina wiped the water from her face, clenched her fists, and smiled confidently, returning to her usual feisty and unyielding self.

...

Meanwhile, in the living room, Tsunade frowned. The Wood Release project still had issues, but certain radicals within the clan were losing patience.

Then there was her deal with Orochimaru. The secret experiments conducted by Root, using children as test subjects, filled her with disgust. Yet, at the same time, the data from those experiments had proven invaluable.

"The atmosphere in the ninja world is becoming increasingly tense. The unresolved issues from the Second Great Ninja War could erupt at any moment. While the major nations haven't made any overt moves, the localized conflicts in smaller nations are growing more intense, and the scent of war hangs heavy in the air."

Rubbing her temples, Tsunade let out a long sigh. There were just too many troubling matters. What a wretched ninja world this was.
