Chapter 36: Making the older generation feel old

Riku was bashing his head against the dining room table repeatedly when Tsunade and Shizune got back home at the end of the day. They both looked at each other wondering what he was doing then the former saw the familiar scrolls on the table.

“Is it that difficult?” She asked; Shizune leaving the room for the kitchen to make dinner since Riku was busy.

“Difficult?! Difficult?! I’m of a mind to find the pedo snake to ask him to bring your uncle back just so I could strangle him. AGAIN!”

“Alright, calmed down.” she said as she approached him and put his hands on his shoulders from behind. “If there is one person that can undert-”

“That’s not the problem, sensei! The problem is that the Nidaime AND the Yondaime are retards!”

The blonde woman was taken aback by the venom and the exasperation from her student’s voice. The word ‘retard’ definitely wasn’t one used for those two men acclaimed as geniuses.

“How so?”

“They both use their chakra directly from their position to go to the position of their anchor. It should be the other way around! The anchor should pull them to it. Less chakra consuming. And don’t let me start on the shoddy space calculations! They’re all correct but overly complicated! They’re trying and succeeding in calculating position in our own world, our own dimension. It’s heavy, it’s long!” he began ranting and Tsunade was already lost, something that he noticed. “Let’s say I create two identical barriers with a ten feet gap between them. The same tags, same anchors, meaning the space or dimension inside of each is part of a whole or identical if you prefer. How difficult do you think it is to calculate the spatial coordinate of a space made of 1m², even if they are separated, in comparison to the whole planet?”

“Not much?”

“Yes! Not much! All they had to do was create a barrier around their anchors like my shurifuins Type-B1 do! Even though in our dimension the barriers are separated by a good ten feet, in the dimension inside those barriers there is no distance between them. Because they are in a way the same space.”

“Because they have the same everything, most notably anchors? Despite not having the same thing inside, one could have a tree while the other does not but it wouldn’t matter because they are not an actual part of the space, they’re just in it.”

“You got it! And so the calculations are short! Well actually they are not but compared to what they did it's like comparing one single word inside a dictionary to the whole dictionary. Furthermore because those idiots take our dimension as reference, they use lot of chakra to go from point A to B and the greater the distance-”

“The greater the amount of chakra needed.”

“Yes! And the fourth! That stupid moronic retard! To make his ‘flash’ go faster than your uncle he’s just using more chakra. Cherry on the cake it’s not ‘I’m going twice as fast so the amount of chakra is twice as big’! That would be smart for him but nope! It’s following a cubic curve! Cubic curve, sensei!”

“That’s ill thought.” she replied not knowing what a cubic curve was but playing along.

“It is!  And do you know what the worst is? The worst of the worst that proves that they are just children who picked a brush and drew some silly doodles and pretended they were seals? Do you know?” She didn’t even have a chance to reply as he went on. “They called it ‘space-time fuinjutsu’ when time is not involved at all! Frauds! That’s what they are! Because if they had used Time they would have won any fight before it began, or counter any jutsu before it was used!”

That caught Tsunade's attention on the spot. The implication she heard in Riku’s words were impossible but when it’s him, impossible just became improbable so she asked for confirmation.

“Riku… are you saying that it’s possible to travel back in time using the Hiraishin?” she asked, completely bewildered.

“YES! KAMI DAMN IT!”

At this point he was breathing heavily, out of steam after such a long rant, while Tsunade had her mind blown away.

“They’re so stupid they make me want to kill myself.” he whined as he turned around to rest his head in her bosom. Instinctively one of her hands reached for the back of his head and caressed it comfortingly.

“How… How would that work?”

“The anchor you want to travel too is surrounded by a barrier whose time has been slowed a lot while the time in… well our own barrier is flowing normally. With the right calculation which I admit are difficult but not impossible, it’s possible to arrive earlier than we departed. It would only be a few seconds at best. Perhaps a few minutes but that would be more than enough. Anymore and it’s time travel shenanigans and I don’t want to touch that with a pole with a length identical to the diameter of the moon.”

If he didn’t want to touch that, then she certainly didn’t.

“That depends how long the anchor you go in has been put in place.”

“How long for the… ‘normal’ version of the Hiraishin?” she asked and Riku sighed.

“Months? No more than six if I spent all my time on it.”

“Alright and the-”

“Years. I’m not going to lie sensei, but years. The theory is easy, the practical on the other hand…”

She nodded in understanding. It took him years to finally get the Time dilation effect down. Adding space to it would no doubt be a more difficult task. She was sure he would succeed however. He had proven time and time again that no matter the goal he would achieve it.

“That also gave me an idea for perfecting the Iryoken. What if I was accelerating the time of the cells at the area where I hit? Or slow it down.”

“Faster or slower cellular division. Either way that will mess the body badly. Or help heal it.”

“I was thinking of perhaps making seals on gloves for it. It could be useful if we simply slow the time of a body during a surgery.” he suggested and her eyes grew big.

‘If the time of a body is slowed, all body’s function would be slowed too giving ample time to a surgeon or a medic to treat a patient! The death rate would drop significantly if not be non-existent!’

“Is it really possible?”

“In theory, yes. Instead of having the time tempered inside a barrier, the body would be the barrier. But the body is organic so it may complicate things a bit.”

Tsunade was in a bit of a conundrum. Riku couldn’t work on all of that alone at the same time. She had to decide what was the most important.

‘Perhaps Karin could help with one of the two? Shizune told me she was working on reproducing her chakra healing capabilities but even faster with seals so no one would be able to heal her.’

“Would Karin be able to help with that medical time seal?”

“Hm… Probably? She’s certainly smart and more than competent enough in fuinjutsu. She hasn’t dabbled in space-time because it doesn’t interest her but Time mainly works with barriers and she’s in a way better at it than me. Perhaps if…we should tell her about the shadow clones. I mean, she’s perfect for that jutsu. She has the high chakra reserves to use its full potential. And now that I think about it, would her clone which is a chakra construct would have her healing abilities? Can you imagine if you could bite a clone and suck up all its chakra? Maybe the nasty side effects of her kekkei genkai wouldn’t apply? Wait, she could also use it with her chains! They’re chakra constructs too! How did I not think of that?!”

Abruptly, Riku stood up from his seat to go meet Karin but was restrained by a hand on his shoulder.

“I think you brainstormed enough for today. It’s also late and she may be busy or tired after a day at the hospital.”

“I… you’re right. Tomorrow. I’ll see her tomorrow.”

“Good! Because I didn’t work on dinner just for you to not eat it!” Shizune said as she entered the dining room, with a tray of bowls. Ramen seemed to be on the menu tonight.

“And Riku… Karin will be told about the Kage Bunshin tomorrow. You’re right. She has proven loyal to the village more than enough times and she’s the perfect candidate for it.”

He nodded at his sensei words and sat back down. The trio enjoyed the meal sharing what went on during their day then went to bed. But not their own. At least not for Riku. Tsunade had dragged him to hers for a cuddling session, with a smirk at Shizune who pouted. The raven haired kunoichi had been given the riot act two weeks ago for ‘perverting young children's minds’. Knowing that she, and not Shizune, had actually been Riku’s first real sexual experience didn’t stop Tsunade from berating (without any heat or reproach) her eldest apprentice. Though secretly she gave her a thumbs up for giving him the opportunity to practice many things. As a consequence and for her own enjoyment in tormenting Shizune, she has been forbidden to do anything ‘funny’ with Riku and would have to use her toy to satisfy herself for a whole month.

When morning came, Tsunade had her breakfast like usual then went to her office. She had sent one of her Anbu guards giving a message to Hiruzen for showing up immediately and another message for Karin to show up in one hour. As usual, she took her time to walk down the streets of Konoha and greet the early risers on her way to the Hokage Tower. Hiruzen arrived just as she reached her destination. Once inside the security to her office, she activated the lock down protocol and pulled out her own Botib from her personal Book of Seals. The old man raised an eyebrow at her actions but quickly understood that what they were about to discuss must be that serious. And boy was he right.

“Two weeks… You’re telling me in two weeks he broke down the whole Hiraishin, the both of them, finding out the flaws, and isn’t that mind blowing? The hiraishin has flaws. Then came up with a better version in theory, that seems sound and workable?”

“Yes.”

Hiruzen took a deep breath to calm himself down. Never in his entire life has he been so glad to have made the decision to get to know Riku himself and tie him down to the village and so thankful to Kami for Tsunade to enter the genius’ life.

‘Had he defected, that would have been the greatest disaster the village would have ever known. Worse than Orochimaru.’

“But that’s not all, he theorized that time travel would be technically possible with it.”

“Of course it would be possible.” he replied flatly, not even bothering to be surprised anymore.

“And he came up with… at least two, maybe three more game changing ideas for Konoha on the spot.” she added and began sharing what she had discussed with her apprentice the day before.

“Hm… Including young Karin is… a good idea. Taking her away from Kusa had been the right decision after all. We could combine the time dilation effect with her training.”

“That’s… an excellent idea, sensei. Why did Riku never think of that?” she asked after blinking in thought for a moment.

“Maybe he did but because spending time in that time barrier, you actually age faster. If you spend a month in there and get out you will have aged a month. In the very long term, it’s not advisable. But with Karin’s chakra reserves that may mitigate it a bit by the use of shadow clones. She may not have a need to spend that much time inside.”

They discussed further the possibilities of what they could do with Riku’s new ideas and exited the Botib. When the lock down on the office was lifted it was just in time for Karin showing up.

On the other side of the village Riku was taking a break by helping train Hinata. Or he was until she took a break herself and the sight of her jacketless self with sweat drenching her shirt making it stick to her voluptuous body distracted him. He silently got close to her and before she could understand what was happening, they were locked in a very sensual kiss full of passion. That had started Hinata’s engine and she was rubbing herself unconsciously against his groin. It didn’t help that he pushed back against her pelvis and his hands kneaded her ass.

“Sorry.” he said out of breath when they separated. “You were just so alluring like that and-”

“That’s alright, I don’t mind. Not when you make me feel like that.” she replied with a blush on her face.

Ever since that sleepover, two weeks ago. Their relationship had moved forward fast. Within limits. There was lots of kissing and petting, Hinata wasn’t so shy with that anymore. Proof of that was her lack of stuttering and her very satisfied smile. More however? They haven’t tried.

“I could eat you whole right now.” he confessed, kissing her along her jawline, then neck then went town toward her throat then lower, only stopped by her shirt.

“Why don’t you then?” she replied with a daring smile.

“And be used as a Juken’s dummy for trying? No, thanks.”

“Maybe you won’t.” she teased.

“You spend way too much time with Ino.”

“Says you. From how I see it, you are the one spending too much time with her with how lecherous you are.”

“Nu-huh.”

“Uh-huh.”

He picked her up, holding her by her asscheeks and she naturally put her legs around him. He walked toward a tree and pinned her against it gently.

“Now what?” asked the bluenette in anticipation.

“Now, I chase away the thoughts of what Ino would do with you in my mind.” he said, making her snort cutely. “Then I let my own guide me.”

He let her down and moved one of his hands under her shirt to touch her bare pale skin. Slowly, so very slowly he moved it upward, taking his time to feel and explore her soft kissable skin. It was also to test the waters, to not make it too fast that she was uncomfortable with what was happening. When he reached her stomach without being stopped, he used his other hand the same way, but this time moving them down as he kneeled in front of her. He lifted her shirt a bit and began to sensually kiss her lower abdomen with butterfly kisses. Sometimes he let it last and sucked on her skin leaving behind a small red hickey. Then he went up bit by bit while his hands, positioned higher than his head went up to, taking her shirt with their thumbs. When he reached her navel he gently blew on it and used his tongue to map every millimeter of it. At this point Hinata put her hands on his head and pushed it towards her. A clear indication she wanted him to continue and do more. Her breath had shortened and her lips delivered sweet but barely audible moans which were music to his ears.

He went up again, and this time the tip of his fingers had reached the bottom of her boobs. He stopped for a moment but kept going when she invited him to do so by pushing his head harder. His fingers slipped under her bra and sank into the flesh of her breasts in a bit of a rougher way than they did until then. They separated to have a better grip and he lifted them up a bit before letting them fall as he stopped supporting them to reach her nipples. They were hard and a bit thin but he didn’t care. He began to caress them with his indexes, drawing circles on their very tip, then changed tactics and tug on them gently. The pressure of the pinch and the tug forced her to let out a very loud moan, that he wanted to hear more. When his lips arrived at her breasts level, she pulled him back, away from her.

He was confused at first, then thought it was as far as she was comfortable to go. He couldn’t be more wrong. Under his very eyes, Hinata got rid of her shirt and her bra then pulled him back head first into her bosom. You didn’t need to tell him what to do. Now with full access to the almost watermelon size breast of his moon princess, he kissed, licked, nibbled and bit as much as he could without inflicting any pain. Hinata’s breath was completely ragged. Shortening further and further with every single little thing he did. It didn’t take him long to understand that her nipples were very sensitive and her weak spot. That was why, knowing she was very close to reaching her peak, he bit one of them. The effect was immediate and even with her biting her fingers to muffle her moans was not enough to hide that she was having an orgasm. Her body shook like a leaf in the wind for a dozen seconds before calming down. Riku got up, put a hand behind her neck and dragged her in for a very hot kiss. She didn’t have the strength to fight it, not like she wanted too. As their tongues acquainted themselves with each other again, Riku’s free hand began to go down her abdomen, reaching the top of her pants. Whether because she was comfortable with it or because she didn’t notice, she didn’t stop him exploring her nether region, slipping under her panties and caressing her pussy. If anything, she moaned loudly in his mouth and became even more into it. He put two fingers in her slowly, her legs closing but not for making him stop but because she felt good. The two digits explored her core but not in depth. They were just twisting around taking a lay of the fertile, wet and warm land they were discoverving. After a bit, Riku pulled them back and removed his hand to put it at his face level. Breaking the kiss and under her lustful eyes, he sucked on his fingers.

He liked it. He liked it alot and moaned at the taste. Sucking all of her juice on them he pulled them out and gave her a peck on the lips then rested his forehead against her. She was still having some difficulty getting her breathing back under control.

“Why?” she whispered but Riku knew the real question was ‘Why did you stop?’

“Because at his rate, we’ll have a little Hyuga in our hands in nine months.”

That drew a small smile on her face. Was it out of amusement or because she liked the idea, he didn’t know and he didn’t care.

“Now, I don’t have a problem with it-”

“You don’t?!” she exclaimed in surprise.

“Not really. I have money and I want a family. Maybe 18 is too young to be a parent but I’m sure we will manage. No, what I have a problem with is Ino exploding on us, either because she was not part of it or because she wasn’t the first.”

She giggled at the thought of a very, very upset Ino, ranting about how she should have been the first to get pregnant and snatching Riku away to make a child herself. Not because she wanted one, but because she was competitive and didn’t like to lose. She also liked to think of herself as the first woman in his life.

“That would be funny.”

“And our funerals, probably. Now… I think you should put your shirt back on because it’s not helping me resist you.”

“And what if I don’t want to?” she teased with an air of defiance.

“You, me, baby in nine months.”

She giggled again, and picked up her shirt she had discarded on the ground. When she went for her bra, Riku snatched it away and put it inside his book of seals.

“Really?” she remarked flatly but her eyes were amused.

“That way I always have something with your smell to remind me clearly of you.”

“And that has nothing to do with the fact that without it, my breasts will jiggle in all directions while I train?”

“...Honestly? I feel ashamed for not thinking about that.”

Hinata rolled her eyes but didn’t fight for her bra back. She didn’t go back to training though. She made him sit down and she sat in his lap, feeling his bulging right under her ass. She still wasn’t ready for that final step but there was a step she was ready for and she needed to ask Ino for help with it. In the meantime, she just enjoyed the nice weather and nature with her boyfriend.
