Chapter 31 (Edited)

"Don't take the trouble; let's wash here fast."

Undressing, when Tsunade arrived with Nawaki at the hot springs, she said, coolly shrinking— Her tone not openly showing her reluctance when her brother was stepping out toward a particular direction,

Nawaki, who stopped walking, wasn't fooled. Despite shockingly witnessing how she didn't shake walking in, Tsunade was evidently still cagey about the idea of steaming water...She had trouble fathoming she was healed...

At that moment, the two of them were in the indoor units of the Senju baths. Which were artificially heated, Roman-inspired, and indoor-built Japanese bathhouses. Unlike the outdoor rockery springs dug within rectangular bamboo pens.

Except for the inconsequential differences in bathing style, his cute sister chose to stay indoors for one singular motive: Indoors, she could regulate the water temperature...

Chuckling to her not-so-covert antics, Nawaki replied plainly with an, "Okay."

He wasn't planning to let her wash with chilly water, anyway...And that wasn't because he cared about his erection but his sister's mental well-being...

There were plenty of hiding places and dozens of water faucets in the indoor bathhouse. Opening one gently and furtively, Nawaki let the temperature heat up.

"What are you doing all the way back there?" Tsunade was done taking her clothes off. Noticing Nawaki's little head peeking out behind a short wall, she frowned tiredly, saying. "...Stop playing hide and seek; come and scrub my back."

Though Tsunade didn't exactly glare when she spoke, she didn't look like she had any energy left for games. She looked more like his sensei than his lover at the moment.

This time, however, Nawaki didn't reply when she stared tiringly. Leaning down as he did his mischievous deeds, he raised the pressure and his head again once the water finally turned warm enough. Respectively.

Ready to cause trouble, he grinned ominously in her view.

"Hmmm? Why are you snickering like that?" Tsunade scowled. "W-Wait, what's the noise?"

Before she could comprehend his grinning behavior or think of a reactive countermeasure, he pulled up the high-pressured faucet from behind the wall and sprayed her.

"N-No!"

"Nawakiii, you jerk!!!"

What followed from Tsunade was a disgruntled yell and a shocked exclaim.

"..."

"Ehh?"

But then...Doused with water, her face looking a little dumb, she noticed the oddity. She was staring at her brother with astonishment. Her arms were still naturally and defensively guarding against his inconsiderate prank when he remarked, laughing,

"Hahaha..."

"...See? Healed. No need to thank me."

*Suck, suck~~

Tsunade was scrubbing Nawaki's back when his boner went fully idiotic. Precum was gushing out of the tip again when she sighed and decided to give him a quick release— One not very typical.

She was sitting on her knees. Giving Nawaki a soaped handjob as he sucked her nipples like a starving newborn.

Drowned underneath her plump, heavy knockers, Nawaki could barely breathe. But he was too overjoyed to care.

XX

Feeling her brother throb from elation, Tsunade, who was feeling very nice too, chuckled, saying, "You can stand up if you want to cum on me."

"...Since we're already here, I'll just wash again."

The moment she said, Nawaki stood. Instantly.

Both of them started rubbing their own genitals. Nawaki was doing that with both hands. He was stroking his giant cock, eyes closed.

Tsunade herself was holding up one of her boobs to suck the nipple, and her other hand was petting her clitoris.

*Cumming!~~

*Squirtt~~

XX

The two of them cummed with emphasis after Nawaki exclaimed, him on her, starting from her forehead,

Tsunade herself spewed her plummy-smelling and angelic-tasting fluids on the tiled bathhouse floor.

Seeing that happen, as he got his cock sucked clean for the last time that night, Nawaki thought it was a waste. So he made a stern resolution...

XX

Nawaki didn't go with Tsunade to her room; the two of them split on the way back for one simple reason they both agreed on,

They shouldn't lie down together if they really want to sleep...

..

Back in his room alone deep into the night, the boy, who was now clean, empty of stress, and refreshed, relaxed, muttering,

"Nothing like a good fuck with my own sister..."

"OOoH...I'm so happy."

He said it out loud because it was the Senju clan. And if Tsunade was worried about Mito, he wasn't.

"Well, since it has turned like this, we'll have to marry." Nawaki already understood Senju traditions. He knew that after what he did tonight, years later, no matter how many girlfriends he got, he'll be advised to marry his sister by Mito and the elders.

She was strong, and strong Senju blood needed to reproduce with strong Senju blood.

Things could go differently if he wasn't planning to advertise their relationship...But how could he not?

He wanted to see Jiraiya and Dan's looks after they learned he was fucking Tsunade. He didn't want other admirers to keep coming to him with love letters either.

Some people like Danzo would be green with anxiety and fear, but Nawaki didn't care. As the Senju prince, people were bound to want his death. And that Shimura guy was first on his list in the future.

He didn't know how his predecessor died in the original work, but it most likely had to do with Danzo. Right? He was involved in everything that harmed the village.

'Thankfully, Hiruzen seems to be a good person in this alternate universe...'

Under his bedsheets, finally going to sleep, Nawaki thought.

'...Grandma said he's prepared a gift for my birthday. I wonder what it is...'

'...He wouldn't be too stingy as the Hokage.'

XX

At the same time, in front of Nawaki's room,

Someone with a greatsword strapped to her back and who had followed him from the bathhouse smiled—Smiled precisely after hearing something surprising that he'd muttered,

She was thinking juicily,

'I didn't think our proud Senju history would repeat with that retarded lass...I don't know why, but she had it out for me from the womb...'

Kanako didn't hate but never liked Tsunade very much. Or Tsunade's mother. This all had to do with them looking slightly like Kanako...Yes, Kanako never wished to concede that the mother and daughter were almost her perfect doppelgangers.

Tsunade often caused trouble for her too. So it never helped with the narcissistic, sometimes egomaniacal issues she had.

'...She's more interesting than I thought, isn't she?'

'...But then again...What should I do with this useless info...Princess incest? That's nothing worth having tea over for us, Senju...'

The person thinking all this, then remembering the nature of her clan, was Kanako Senju. Nawaki's oldest aunt. She wasn't a busybody, but now she was in charge of the night guard.

These days, she was not just irritated with her cousin Tamatsu but a little with her niece Tsunade...It just wasn't as easy to cause trouble for the latter. For a lot of reasons...

..

Minutes later,

Waiting for her nephew's breath to change, when she knew he was asleep, Kanako entered his room,

Ignoring the fearful maids, after verifying something, she left smirking. Finding out she had big business with the man— only little in age— in the room, she temporarily retreated. Greedily Licking her lips...

Apparently, Senju history repeating itself didn't have much to do with her niece being dapper than she imagined...Her nephew was packing something too nice not to give it a steamy ride in the hot springs...

Kanako Senju...This woman— a barbaric greatsword master who typically loved things large in size, was from an old and difficult Senju school. A school similar but which also differed greatly from Butsuma Senju's...

With all that said, however, apart from Mito, she was the closest relative in blood to Nawaki and Tsunade. She was their mother's big sister.

XX

Early the next day, Tsunade was going to be busy today with mental patients; she had tests to conduct for the sake of her new sister,

Waking up after she left, Nawaki recalled that he needed to meet and have lunch with his school buddies from the Ino-Shika-Cho when he arrived at said sister's room,

"Nono, are you sleeping? I'm coming in," At the door, the boy knocked and said. It was still early, but he wanted to see if she was ready to go and have breakfast with him and Mito.

Her having to attend school wasn't until a lot later, so it was smarter to let the girl sleep in a little. However, school seemed to be a joke for Tsunade; Nono wouldn't go long if she kept going.

Because it was like this, naturally, Nawaki wanted to spend quality time with his new sister. He liked her very much already.
