Chapter 44: Lot of works to be done

Tsunade woke up in a good mood. Sore but in a good mood. For the first time, Riku had used shadow clones during their intimate time and that had been quite a challenge. She didn’t regret it though. Either the involvement of the clones or the act itself. He was her apprentice, her friend, her son but also her lover all in one. And she wouldn’t change a thing. The previous night had been way more intimate than they ever did previously. And if that was wrong? Then she’d be wrong and keep on doing it.

She couldn’t help herself and looked happily at her son, his head buried in her chest. She wanted one thing in that moment and that was to let her hand roam through his hair. She knew what such a thing would lead to however. Many more rounds of sex. Massaging his scalp, completely unleashed him. She had felt that while he pressed her against the mattress from above. She had grabbed his head and he went all the harder on and in her. No matter what she said, he was lost to lust at that moment. She didn’t complain, quite the contrary but she sure as hell won’t be able to take that kind of pounding the whole night let alone everyday. She was quite glad that he had girls in his life. Speaking of girls, she worried about what Shizune and Ino would say when the news would be out that they were mother and son. That was a problem for future Tsunade though so she put it out of her mind.

Thinking about Riku's parentage made her think of Naruto’s. The boy was not much of a boy anymore by being nearly 18. Tsunade could understand why Hiruzen had hid from him who his parents were; Naruto was young, couldn’t protect himself and was such an attention seeker from what she was told that he would probably have blurted out the secret. Had Iwa or maybe even Kumo known whose son he was, assassins may have been coming endlessly to take his life. Considering that the Kyubi was sealed inside of him, had Naruto died the fox would have been free right in the middle of the village. Again.

No, not telling Naruto about his parents was the smart choice at the time. Now? He was still a bit naive and immature but he wouldn’t blab about it. That left the relation with Riku up in the air. Should she tell him or not? Considering that Riku and Naruto didn’t particularly like each other it was better not to. There was also Jiraiya to take into consideration. He had viewed Minato as his own son and saw Naruto as his grandson. Would he see Riku the same?

‘So many questions. All for later.’

She tried to push Riku away gently so she could get up but failed. He used his hands to hold onto her beasts and wouldn’t let go without possibly ripping them off.  While she wouldn’t mind her breasts recovering their normal size she didn’t want no boobs at all. She thought for a moment and simply created a shadow clone. A very naked copy of her which was standing up, laid down on Riku’s back and tempted him with her own factice breasts. A few enticing words in his ear and Riku let go of the original Tsunade and turned around to latch himself on the clone. The chakra construct then rolled them around so Riku was back into his starting position: head buried in her cleavage.

Now free, Tsunade got up and left her bedroom. As she turned the corner of the corridor leading to the bathroom, she came across Shizune.

‘Shit! I totally forgot about her!’

“Good Morning, Tsunade-sama.” the raven haired kunoichi said with a teasing and knowing smile.

‘She must have heard us the whole night.’ “Good Morning, to you too.”

“Taking an early bath?”

“You can drop the act, Shizune. Now if you don’t mind and as you can see, I’m in a dear need of a shower. You’re free to join.”

Tsunade wasn’t wrong. She may have had her womb and ass full of Riku’s seed but her breasts and neck had been completely painted white multiple times. Riku wasn’t able to resist sliding his dick between her beauties and honestly, she couldn’t blame him. She would have done the same.

Shizune accepted her invitation, or rather jumped at it, and followed her inside the bathroom. After cleaning themselves up, they enjoyed a hot bath together.

“How is the situation, Tsunade-sama?”

“If you mean regarding Danzo then he’s dead. The bastard destroyed my office while doing so but almost no one was hurt.”

“Almost?”

“Koharu lost her right forearm but Riku already fixed it. She’s very happy with her new prosthetic.”

“Speaking of Riku, is his… problem solved?”

“Yes, and no. Depends on which part.”

“Which part? What do you mean?”

“Riku is the product of an experiment conducted by Danzo to… well, recreate the fourth Hokage.”

“Oh.” was the shocked answer of her eldest student. “I…This… What can I say to that? On one hand the experiment seems successful as I believe that Riku would make a great Hokage one day, on the other… That implies that…”

“His mother was a root agent. His father, just an idiot in love.”

“Was his mother’s arres-.”

“All staged by Danzo.”

“Despicable.” Shizune commented with a grunt. “Using a woman’s child to…”

“Riku wasn’t her child. She carried him for nine months but they’re not blood related in any way.”

“Y-you mean… They succeeded in doing an in vitro conception?!”

“Yes.”

“Who are Riku’s parents then?”

‘It’s break or swim.’ Tsunade mused. “Namikaze Minato and I.”

Shizune’s head turned so fast, Tsunade was surprised she hadn’t broken her neck.

“YOU?!”

“Apparently.”

“B-but! That means… Riku and… and…”

“Yes.”

“Oh. And you still…”

“Yes. What’s done is done. It’s been two years anyway at this point. No reason to stop because we now know about it. It’s not like we can have children so there isn’t any reason not to pursue our relationship beyond societal impropriety.”

“...Kinky.”

“What?!” the blonde exclaimed, this time her own head turning to look at the woman beside her.

“Didn’t know you had that kind of fetish, Tsunade-sama.”

“I do not! It’s… Riku being my son is last on the list of the many things he is to me.”

“If you say so.” Shizune dropped the conversation with a knowing smirk.

Nothing more was said for a while. Until they heard Tsunade’s own voice screaming in ecstasy.

“He sure doesn’t mind.” teased Shizune, understanding that a shadow clone was with Riku. Her sensei didn’t even give her an answer. There was no point in her opinion.

Five minutes of moaning later and Tsunade had had enough. She dispelled the clone to stop the embarrassing noises it was making. That was a bad call because she remembered everything the clone experienced and that switched her internal engine back on. Raising from the bathtub, she went to take a very cold shower and after drying herself left the bathroom and a very amused Shizune.

‘Note to self; next time use shadow clones on Riku.’

She entered her bedroom and saw a very unhappy Riku under her sheets.

“That was very cruel, mom.”

“Maybe next time you’d put up the soundproof seal? That way the whole manor won’t hear your sexual escapade. Shizune was very amused.”

“Oh. I forgot about her.” Riku replied with a bit of shame on his face.

“So did I. Now get up. Time to start the day.”

He almost let out a retort about her already being an annoying mom after only a day but kept quiet. That would have been bratty of him and she was right. He had plenty of things to do. He got up and went to hug her from behind, his hands taking her boobs in them from below and lifting them up, juggling them gently and his dick sinking into her butt’s crack.

“You really can’t help yourself, can’t you?” she said, doing her best to not sigh

“Only with you. I guess… I want to be spoiled.”

“We’ll have all the time tonight.”

“True.” he admitted. “I’ll have clones keeping on testing the Hiraishin prototype and a few working at the hospital’s basement. I’ll also have a look at the cursed seal. Anko had suffered enough from it. That is if I’m not needed anymore to comb through that asshole’s files.”

“That’s a good idea actually and no. You’re good regarding the files, there are more important things for you to do.”

Riku kissed the back of her neck and released her. Quickly he went to the bathroom and found Shizune still enjoying the hot bath. Of course, since he was still erect (he had been stopped in the middle of things after all), he didn’t miss the opportunity. He put a sound proof seal this time and meticulously took care of giving his senpai the best morning ever, to her greatest joy.

Afterwards, he did as he planned. He created clones to test his prototype and a few more to work on the Hospital’s basement. He, the original, began to work on the curse seal. Orochimaru’s notes were very informative. The cursed seal did three things.

One, was releasing an enzyme inside the body changing bit by bit the brain chemistry. The subject grew more violent when the seal was active, less rational and addicted to the sensation the seal was giving them.

Two, the  seal was releasing nature chakra. That has been a new one for Riku. The knowledge that nature chakra, a new type of chakra, existed beyond the yin and yang was mind boggling. He wondered why no one knew about this. Regardless, it was this chakra that helped the body transform and the production of the enzyme.

Three, and here Riku nearly lost his mind, the seal contained a part of Orochimaru’s soul. In other words, the seal was designed for Orochimaru to take over the body more easily and make it permanent. It also made it so if he died he could be “resurrected” thanks to the seal.

Here and there, Riku decided to remove the seal from everyone who had it. Orochimaru couldn't be allowed to stay alive, dormant inside the seal or not. That gave him an idea for the Edo Tensei and he made a clone to pursue that thought.

His musing was stopped by a sudden visit from Hiruzen.

“Sandaime-sama. Please come in. I’m not going to lie, I’m surprised at your visit.” Riku said, inviting him inside. Quickly, he led him through the living room to the patio  where they sat down on the wooden floor (on pillows) to have some tea.

“I just wanted to check on you. I briefly saw you yesterday and you left too quickly for me to ask questions.”

“I thought  it was better that way. It seems to me like a team moment and I didn’t want to intrude further.”

“Hm, you may be right on this. IT’s been years since Koharu, Homura and I just… talk and laugh like we used to. Before I took the hat and responsibilities and duties piled on our shoulders. For the first time in years we sat and just drank and talked. Good times.”

“I supposed that it’s a very good lesson for when I’ll be Hokage. Never forget to enjoy what I’m working for. What’s the point of protecting the village if I don’t enjoy the village from time to time to remember why I’m doing it in the first place?”

“Too true. I wished I had known that beforehand. That would have made the job more pleasant.”

“I’m fine by the way. Sensei being my mom… Well… That’s the best news I’ve ever had.”

“Really?”  Hiruzen asked in surprise. That wasn’t what he expected at all.

“Yes. Being related to the Yondaime and Naruto on the other hand…That’s my problem. He’s going to be insufferable when he finds out about it. The simple thought is already giving me a headache. I already have two loud blondes in my life, I don’t need a third. Especially one that will do his very best to connect with me because ‘we’re alike and we suffered too’.”

That made Hiruzen chuckle. He knew Tsunade and her temper well and he has been made aware of his son’s team’s kunoichi. Yamanaka Ino seems to be just as troublesome.

“That asks the question when will he be told of his parentage?”

“Today, actually. Tsunade decided it was time.”

“He’s not going to be happy with you.”

“No.” Hiruzen replied with a tired sigh. “I did what I had to do for the village and him at the same time. He didn’t make things easier with his behavior.”

“He’ll get over it. One thing I respect and admire about him is that should you truly be sorry for what you did, he’d forgive you and let it go. A bit naive for a shinobi but it’s endearing.”

“That it is. It gives me hope for a better future.”

“Yours or the village?”

“Both. Mainly me as he still needs to grow up and mature a bit more for the village. He is getting there, however. Now enough about Naruto, you’re the one I came to see and talk to. Tsunade said you were done with the hiraishin?”

“Yes. The prototype is being tested by some clones but the results so far are excellent. Good enough that I started to work on removing the Orochimaru cursed seal to kill him for good.” the tidbit of information made Hiruzen’s brows go down into a nasty frown.

“For good?”

“He put a piece of his soul inside the seal. As long as there is a piece somewhere he could come back.”

“Then removing those seals is a priority.”

“It is. I’m a bit stumped though because he’s using something he calls ‘nature energy’ or ‘nature chakra’. Since I don’t know what it is and what that does I can’t recklessly break down the seal like I would usually do.”

“Nature energy is just that. Nature energy. It’s all around us. In the air, the earth, the water… Anything that is organic but not sentient.”

“Not sentient means no spiritual energy, so no Yin chakra.”

“Correct. And I see your question coming so I’m answering it now. Nature energy doesn’t depend on Yin and Yang chakra, it's its own chakra. More unrefined, more raw, more… natural. By taking that energy into your own body you become what is called a sage and your body capabilities are enhanced extremely.”

“There must be a real downside to that, otherwise everyone would be a sage.”

“A great downside, yes. By taking nature Energy inside your own body you need to balance it with your spiritual and physical energy otherwise… You’d probably die. As I said, nature energy is… wild and powerful, finding the good balance between the three when you spent years finding balance with only two… Difficult. Your great grandfather was a sage himself, he may have a few scrolls on Senjutsu. Maybe they could help you with the seal?”

“I’ll have to ask mom about them.”

“Mom, huh?” smiled Hiruzen and Riku just shrugged.

“It’s in private for now and I have already been seeing her as such for years already. I’m just verbalizing it.”

They each drank their tea in silence, taking advantage of a lull in the conversation.

“Studying the seal made me think of the Edo Tensei. I believe that a real resurrection, not into a corpse but into flesh and blood, is possible.”

Hiruzen put his tea cup down and pondered for a moment.

“The dead should stay dead, Riku.”

“I know. I won’t argue about that. Although some should not be dead. Naruto should have his parents with him and the village would only be stronger with them back. Of course it would be their choice if they wished to stay or go back to the pure lands.”

“You just want to punch Minato for being an idiot.”

“Maybe. But what about Kushina? I’m not related to her in any way.”

“One more Uzumaki member? One with the adamantine sealing chain, a seal mistress and an excellent swordmistress and… Okay that sounds really nice to have them both back. You led me to convinced myself, huh?”

“Well… genjutsu is a bit overrated in my opinion.” the cheeky grin on Riku’s lips made Hiruzen’s eyes twitch in irritation.

‘That brat! Manipulating me! Me! Kami, I’m old…’

“Let’s say Tsunade agrees to this. How are you going to make them flesh and blood again?”

“That is the hard part. We need their own yang to properly connect with their yin. In other words their own body to connect with their soul. I have no clue how to start with that but given time I will find a way. But it’s neither here nor there.”

The subject was dropped and the conversation turned towards more mundane things. One of them was Hiruzen’s grandson who would participate in the chunin exam that will take place in Konoha soon and about his hilarious relationship with Hyuga Hanabi. Konohamaru was really a source of endless entertainment to the aged man.

After a while, Hiruzen excused himself and left. Wanting to take a break from his brainstorming, Riku got out of the manor and went to see Kakashi and Yugao, probably still in the Root HQ. It was proven right when many teams of Anbu were swarming the place and Kakashi along with Yamato were giving orders right and left.

“Kakashi, Yamato-san.” the dirty blonde greeted.

“Riku. I’m surprised to see you here after… yesterday.” said the cyclops.

“Meh, it’s fine. I got over it.”

“You got… over it?” was said in a very skeptical tone.

“Yeah.” was the nonplussed answer Riku gave. “I came to check if there was any seal that needed my expertise.”

“Not to process everything?” Yamato asked, finally entering the conversation.

“Nope. The Hokage said that I’m officially off-duty due to some… life changing revelation from the previous day. So I’m just enjoying my fuinjutsu hobby and if that leads me here in the lair of a paranoid man with a penchant for cursed seals then all the better for everyone, no?“

“That’s… I don’t even know what to say. Way to go in abusing the system to not do the annoying work, I guess?”

“I’m a ninja. Finding ways to go around things is a skill.” joked Riku to an unamused Yamato.

“There is one seal we need your help with, actually.”

“Oh?”

Kakashi signed to follow him with his hand and led him to the deepest part of the complex. After a good ten minutes walk, they arrived at a huge metal double door. The numbers of seals on it were staggering.

“Holy… That seal matrix is freaking huge! What must be beyond that door is definitely something important.”

“I think so too. I sent Pakkun to give the Hokage a message about it one hour ago. She replied that Jiraiya would be in the village soon to take care of it.”

“I could do the job but it will take time, I’m not quite there yet in my seal breaking skills. Karin may be back from her mission.”

“She doesn’t really have the clearance you know.”

“But she’s the only seal mistress who can deal with this at the moment. She’s also Shizune's apprentice and privy to some S-rank secrets because of her skills. I don’t think sensei will object but I’ll send a clone to ask for permission.”

He created a clone who immediately left. In the meantime he pulled out a notebook and began to take notes of his observation with the seals. He didn’t even notice Kakashi leaving and coming back an hour later with Karin.

“Holy… That seal matrix is freaking huge!” the redhead exclaimed and made Kakashi snort.

“Riku said exactly the same thing. Now, I’ll leave you both to it. Warn me when you find a way and do not undo the seal without me present.”

Both Karin and Riku waved him away without giving so much as a look. They were too focused on the seal to pay him any mind.

‘It’s sensei and Kushina-san all over again. When seals are involved, nothing else matters to them.’ he thought with a tired chuckle as he left.

“I think the weak point of the matrix is this symbol here.” Riku said after a while pointing to the top Right of the door.

“Hmmm…. It is but there is a problem.”

“It’s connected to three double anchors.”

“Six actually.”

“Huh? Six?”

“Yes, look. The three you saw are directly linked to the symbol but if you look closely, it has six … ‘hooks’. And here.” she said, pointing out one of the three Riku missed. “They’re not connected to anything but you can tell from the chakra that it’s-”

“No, I can't. I don’t have your sight Karin. I can’t see chakra.”

“...I forgot. Sucks to be you then.” she joked, making Riku growl.

“Kekkei genkai are bullshit!”

Riku said that so often that Karin joked it was his own verbal tic, like hers was ‘ya know’. She found it cute, so much that she grabbed him by the arm, turned it around and kissed him right on the lips.

“So… I guess you’re in then?” he inquired after separating his mouth from hers.

“Yep. I still find it weird but between Ino’s relentless madness, Hinata’s sinful body and you… I couldn’t really say no. I mean… Our relationship is still the same, we all loved each other before. Now? We just love each other more and sex is involved. Back to the topic at hand though or we’ll never open that seal.“

“Hm. Seal now, love later.” he agreed and turned back to the door. “So, How do we do this? The anchors needs to be undone at the same time but there are six and -”

Golden chains sprouted from Karin’s hands - six to be exact- and each one of them touched one of the anchors.

“Kai!”

The redhead channeled her suppressing chakra ability through the chain and the anchors dissolved. As a result the symbol dissolved too and the whole matrix began to fail in an epic chain reaction.

“... Kekkei genkai are-” he was stopped by Karin putting her tongue in his mouth for a brief moment. When she pulled back, she looked amusedly at him.

“I know.”

The lovey dovey moment stopped there and they pushed the heavy door open. What they found inside was fuel for nightmares. Dozens of medical pods filled with green or blue transparent liquid. Inside were body parts. Arms for most of them. Uniquely deformed and disgusting to look at. Sometimes the face of Senju Hashirama was present, sometimes not. It wasn’t what caught Karin and Riku’s eyes as they explored this lab of horrors together. No, it was the redhead woman with a giant hole in her abdomen floating around a clear liquid that caught their attention. The woman was clearly dead and from what they could see it happened very shortly after giving birth. All thanks to her very distended stomach.

“Holy crap. I think… I think that’s Naruto’s mother.” whispered absentendly Riku. Karin didn’t miss it though.

“His mother? Why would she be kept here as a … trophy? Lab rat?”

“I… “ he wanted to say that she didn’t have the clearance for it but she already knew about the Kyuubi, Naruto and Uzumaki Mito, the first jinchuriki. “She was the second host.”

“Of the fox?!”

“Yes. As for why she’s here…I’m not sure if I can tell you.”

“You can’t.”

They turned around and saw Kakashi standing behind them.

“What happened to: ‘Warn me when you find a way and do not undo the seal without me present.’, Hum?”

“You said something about that? Did he?” Karin asked Riku who shook his head.

“Not that I remember.”

‘Bloody fuinjutsu nerds.’ “I did.” he replied then looked up at the familiar redhead he hadn't seen in nearly twenty years. “It is indeed Naruto’s mother, Uzumaki Kushina and she should have been buried next to her husband.”

“You can say his name, you know. I found out years ago the Yondaime is Naruto’s father.”

“It’s the whiskers.” Riku explained and Karin nodded in agreement.

“The whiskers.”

Ignoring their unknowing attempt at humor, Kakashi diverted his eyes from Kushina and looked at the two young adults with him.

““No words of this to anyone but the Hokage. We know.””

“Mah… You’ve been trained well.” the cyclops joked with an eye smile.

“What should we do? Seal the place back up or put everything into my Botib?”

“Hmm…Seal the place for now. We need to tell the Hokage first. She will decide what we do with all this.”

With a new task on their hands. Karin and Riku began to seal the door from the outside. Riku left an anchor inside the room to be able to come and go with a simple reverse summoning. Once done, they went to see Tsunade.
