The Partial Expansion Jutsu isn't all that difficult.
After a few days of practice, Natsume fully mastered it.
After that, life became completely dull and uneventful.
In the morning, he trained in Sage Mode.
In the afternoon, he sucked Hinae's milk to replenish chakra, then worked on his ocular powers.
At night, he became Tsunade's hugging pillow.
In the deep night, he'd sneak out for a while to feed Hinata.
Occasionally, Natsume would drop by to see Naruto and Sasuke, just to remind them of his existence.
…
…
…
Time flew by.
Three years passed.
Natsume looked through his camera, watching Hinae's movements.
She was sitting on the sofa, her legs in black over-the-knee socks naturally crossed, revealing a red view under her pleated sailor skirt.
Her top was also red. Her hair was tied into twin tails with a black ribbon, and she was holding a pair of round-toed leather boots in her right hand.
Today, Hinae was cosplaying as Rin Tohsaka.
From the Type-Moon series.
Hinae was no slouch either.
Her thighs were full and shapely, her calves slender and proportional, her curves perfect.
After the photoshoot, Natsume stretched lazily.
But there was still plenty of time, so he didn't want to waste it.
Hinae's fair feet, wrapped in black over-the-knee socks, gently stepped on Natsume's back, giving him a massage.
Her face was flushed, clearly not used to this.
In this world, because of the existence of nobility, it's closer to ancient Japan.
Etiquette is the same; women are expected to be virtuous wives and good mothers.
Things like this, in Hinae's view, were utterly absurd and incomprehensible.
Especially given her naturally gentle personality.
Natsume finally understood why men like to urge others to turn over a new leaf during post-nut clarity.
He secretly thought how nice it was to have an automatic waifu.
After a while, Hinae's legs became weak, and sweat beaded on her forehead.
"You're tired too. Now let me give you a massage."
Natsume let her sit down and crouched in front of her.
He took her soft ankle in his right hand, and his left hand gently slid along, making a rustling sound.
Hinae instinctively straightened her legs.
Natsume smiled, took off her black over-the-knee socks, and revealed her jade-like bare feet.
Hinae bit her lip, soft and loving eyes rippling with emotion, her toes curling nervously.
Natsume patted her arched foot, massaged her delicate toes, and gradually let her relax.
He slowly moved upward.
No one knew how much time passed, but Hinae had already fallen soundly asleep.
Was she that tired?
Natsume didn't disturb her.
He got up to check the time—it was already noon.
Might as well cook something.
Why could Natsume cook?
With just ten Fate Points, you could become a first-class chef.
A huge bargain.
He remembered this one day when he was delivering a late-night snack to Hinata.
Cooking for himself saves money, after all.
More importantly, it moves people and makes them feel valued.
It has double the effect for raising affection.
See, Hinata had already gone from wanting to pay him back to wanting to cook for him in the future.
Natsume opened the fridge.
Because Hinata liked chicken legs, it was mostly filled with chicken.
He stroked his chin, finally deciding to make Stir fried chicken.
As Natsume cooked, Hinae walked into the kitchen.
"You're awake? Wait a minute, I'm making Stir fried chicken."
He heard the sound, but didn't turn back.
Stir fried chicken?
Hinae was a bit stunned.
After years of learning various foreign languages from Natsume with Karin, even if he translated directly, she could understand.
"Smells so good. I want to taste it soon."
Hinae sniffed, then couldn't help but swallow.
"You can have it sooner."
Natsume suddenly whispered a few sultry words in Hinae's ear, his hot breath tickling her skin. "I want to feel your lips wrapped around me," he murmured seductively.
Hinae's eyes instantly filled with shyness, a deep blush creeping across her cheeks. Her heart raced as she processed his request, feeling a mix of excitement and nervousness.
Just as Natsume thought she was unwilling, Hinae surprised him by slowly bending down on one knee. She looked up at him with a coy smile, her eyes sparkling with mischief.
With trembling fingers, Hinae reached for Natsume's belt, fumbling slightly as she unbuckled it. The sound of his zipper being lowered seemed deafeningly loud in the quiet room. Natsume's breath hitched as Hinae gently freed his already hardening cock from the confines of his boxers.
She wrapped her delicate fingers around his shaft, marveling at how hot and smooth it felt against her palm. Hinae began to stroke him slowly, her grip firm but gentle as she explored every inch. Natsume groaned softly, his hips instinctively pushing forward into her touch.
Feeling emboldened by his reaction, Hinae leaned in closer. She parted her lips and tentatively licked the tip of his cock, savoring the salty taste of his precum. Natsume's hands tangled in her hair, not pushing but simply holding on as if to ground himself.
Hinae took a deep breath, steeling her nerves, before taking him fully into her mouth. The weight of him on her tongue, the stretch of her lips around his girth - it was an entirely new sensation that made her head spin. She began to bob her head, hollowing her cheeks as she sucked.
"Hinae," Natsume moaned, his fingers tightening in her hair. "That feels amazing."
Encouraged by his praise, Hinae increased her pace. She used her hand to stroke what wouldn't fit in her mouth, twisting slightly on the upstroke in a way that made Natsume's thighs quiver. Her free hand cupped his balls, rolling and squeezing them gently.
Natsume couldn't tear his eyes away from the sight of Hinae on her knees before him, her lips stretched wide around his cock. The wet, obscene sounds of her sucking filled the kitchen, punctuated by his own breathless gasps and groans.
Hinae pulled back for a moment, catching her breath. A string of saliva connected her lips to the tip of Natsume's cock, glistening in the dim light. She looked up at him through her lashes, her cheeks flushed and eyes dark with desire.
"Am I doing okay?" she asked shyly, her hand still stroking him steadily.
"You're doing incredible," Natsume assured her, his voice rough with arousal. "Don't stop, please."
Hinae smiled, a surge of confidence flowing through her. She leaned forward again, this time focusing her attention on just the sensitive head of his cock. Her tongue swirled around it, tracing patterns and flicking across the slit in a way that made Natsume's hips jerk.
As she continued to pleasure him with her mouth, Hinae's hand moved faster along his shaft. She twisted her wrist on each upstroke, adding a new layer of sensation that had Natsume seeing stars. His breathing grew more ragged, his moans more frequent as he approached his peak.
"Hinae, I'm close," he warned, his fingers tightening in her hair. "You don't have to-"
But Hinae had no intention of stopping. She took him deeper into her mouth, relaxing her throat as much as she could. The tip of his cock hit the back of her throat, making her gag slightly, but she pushed through it. Tears pricked at the corners of her eyes, but the sounds of pleasure Natsume was making spurred her on.
Natsume's hips began to move of their own accord, thrusting shallowly into Hinae's willing mouth. She matched his rhythm, her hand and mouth working in tandem to bring him to the edge.
"Fuck, fuck, fuck," Natsume chanted, his whole body tensing. "I'm gonna-"
With a final, deep groan, Natsume came. Hot spurts of cum flooded Hinae's mouth, catching her by surprise. She swallowed reflexively, the bitter taste flooding her senses. Some escaped the corners of her mouth, dripping down her chin, but she did her best to take it all.
Much later, as the last aftershocks of his orgasm faded, Natsume shuddered and exhaled deeply. His legs felt weak, and he had to lean against the table to keep from collapsing. He looked down at Hinae, still on her knees before him, and felt a surge of affection mixed with lingering desire.
Hinae slowly pulled away, releasing his softening cock from her mouth with a soft 'pop'. She wiped her chin with the back of her hand, looking up at Natsume with a mix of shyness and pride.
Natsume thought it was a bit of a pity that it was over so quickly. He wanted nothing more than to return the favor, to make Hinae feel as good as she had made him feel.
Hinae swallowed the last traces of his release and said, "I'll go wash my hands. We can eat soon." Her voice was slightly hoarse, a reminder of what she had just done.
She turned and quickly ran to the bathroom.
...
Stir fried chicken is really good.
Natsume and his little brother were both very satisfied.
After lunch, Natsume returned home.
Tsunade was sitting on the sofa, her eyes blank, apparently spacing out.
"Big sis."
"When did you get here?"
Tsunade jumped, snapped out of her daze, and asked.
"I just got back. What are you thinking about?"
Natsume sat down beside her naturally and played with her hand.
Tsunade thought to herself, it's just like this.
More and more dangerous.
A few years ago, she could comfort herself because he was a little boy, but now he was a big boy.
It was time to draw the line and separate appropriately.
"Natsume, I have to go to the Land of Fire tomorrow for a mission."
Tsunade said seriously.
Natsume was stunned for a moment.
After so many years, he knew Tsunade very well.
That was the tone of lying.
He thought for a moment and understood the reason.
She wanted to distance herself, to calm down.
But sometimes, the further apart, the stronger the feelings become.
Fine.
Natsume could take this chance to go to Kirigakure himself and earn some Fate Points.
If he didn't go soon, Terumi Mei and the others might discover that the Fourth Mizukage, Yagura Karatachi, was being controlled.
As for Sage Mode, he had already mastered it.
He was just pretending all along.
Slug Sage was very cooperative, too.
As a creature that had lived for over a thousand years, age meant nothing to it.
It had watched Tsunade grow up and naturally wanted her to have a good ending.
"Twelve Guardian Ninja of the Land of Fire's Daimyo had some issues."
Tsunade thought he didn't believe her, so she explained, "The old man's son, Sarutobi Asuma, is one of the guardians now, and that's why he wants me to check out what's happening."
Natsume nodded.
In the original, the Twelve Guardian Ninja split because of differing ideals.
Kazuma's faction believed the Land of Fire should have only one boss—the Daimyo, not the Hokage Sarutobi Hiruzen.
Sarutobi Asuma disagreed—after all, that was his father, so he naturally supported him. Thus, the Hokage's faction formed.
The two factions fought.
In the end, Sarutobi Asuma won, and Kazuma went on the run.
Now, with Tsunade joining, the outcome was even more certain.
[Because of your actions, the destiny of Kazuma and the other Guardian Ninja has changed. You gained 89 Fate Points.]
Not bad, he could even get some Fate Points from this.
And this notification proved Tsunade's trip to the Land of Fire was because of Natsume.
The mission was just an excuse.
"Okay, big sis, be careful. Go and come back soon."
Natsume obediently said, "Sage Mode is fine, Slug Sage is there, so don't worry."
Tsunade was taken aback and felt a little guilty.
But she quickly hardened her heart.
