Unlocking the Legend

The first thing Kushina did after their talk was creating a schedule for Naruto to follow daily. Since Naruto lived alone in an apartment there was no restriction on him, which was good in her book. Since after the Third Shinobi War the Academy didn't accept any children under 12 year for Shinobi training, so he had two years all to himself for developing and sharpening his own skill and get a massive head start on the rest of the kids of his age

Naruto had to wake up at 5:00 am and got only 30 minutes to freshen up, he had exactly one hour for preparing and eating his breakfast, ten minutes for reaching Training Ground no. 44 aka Forest of Death. That particular training ground is dangerous so there wasn't much security to stop any intruders, only a fool would be stupid enough to enter that place. Fortunately, Kushina used to train there in her early days and knew every bits and corner of the place. She had made a small seclude area at a corner of the forest with a small cabin for resting; the area was secured by many seals to prevent wild animals from entering. Naruto just had to charge the seal with his chakra to activate it. From 6:40 am to 9:00 am, he would train his body with ten minutes break after every hour, while for a ten-year-old kid he got a nice body if he want to remain a civilian; it was not enough for a shinobi and still had too much baby fat on him.

He also met a crazy woman named Anko in the forest; she like him was also not liked much in the village though he still did not know why. At first she questioned him what was he doing in such a dangerous place, he told her for training. She leered him suspiciously for few moment then shrugged it off and started normal chatting. They became great friends after some time, she would occasionally watch him train and while a little surprised with his skills she didn't told about it to anyone. She would sometime even tease him when she took bath with him, much to his chagrin.

After that came the bane of every Shinobi's carrier, Chakra Control. Moreover, in Naruto's case, you can say it likely his main enemy being an Uzumaki and container of the strongest tailed beast. His chakra pool was already as massive as a Low Jōnin and with terrible, no horrible control over it; his chakra was like a wild fire, untamable. This lead to the addition of meditation and chakra control exercise from 9:00 am to 12:30 pm with ten minutes breaks after every hour. After that Naruto would took a long needed bath in the lake near the cabinet for say almost 30-45 minutes, he would have till 3:00 am to go back to his apartment, cook, eat and rest or a nap.

From 3:00 pm until 5:00 pm, Kushina taught him academic studies, tactics, manners (the irony of the situation) etc. She didn't want her son to become a killing machine with no brains and socially awkward.

After that, Naruto was free to do anything he wants until 7:00 pm. At seven he would start preparing his dinner and finish eating it until 9:00 pm followed by sleeping time. More or less, that was his daily training regime for him made by Kushina and Kurumi. The mightiest fox did not wanted her host to be a weakling even if the said host is her best friend's son.

With that training regime, Naruto started his training days.

During the beginning, Kushina found that Naruto had inheritated the Namikaze clan's High-speed movement ability; while she may hate Minato she wouldn't deny any useful abilities that may help her son. She told him everything about it, basically due to this ability a person have more than normal amount of chakra pathways and tenketsu points in his/her body for more speed and better reflexes. Normally every human have 361 tenketsu points and that's a fixed number, when Kurumi scanned his body with how little permission she had given by the seal she found Naruto has 430 tenketsu points, the difference in number alone says for itself. Minato had 400 tenketsu points and what he did with them? well you can ask Iwa shinobis.

Improvement of the said ability was also added in the physical training session of his training regime.

It took him about week to properly gain control over his massive chakra reserves and another four days to master the Leaf Concentration exercise, in which he had to stick a leave on his forehead with only the help of his chakra. Kushina started his Tree Walking exercise as soon as Naruto was done with Leaf concentration exercise. Tree Walking took him a full week to master but the result was clearly visible, he could even dance upside down if he wants to now. Kushina did not stopped there she even taught him Water walking exercise, it took the most amount of time out of all the chakra control exercise, solid two weeks. After which Naruto could easily run or even perform somersault on the water surface without any problem.

After when Naruto gained decent control over his chakra, Kushina added light Ninjutsu practice with the control exercises. She taught him the basic Academy level jutsu first, the Kawarimi and Henge no Jutsu. She knew he would not be able to execute the basic Bunshin as till date none of their ancestor was able to perform it. In Uzushiogakure Shinobi Academy, they used to directly taught Kage Bunshin no Jutsu instead of normal one. She also explained why Kage Bunshin was considered as an Kinjutsu and its pros and cons, main pro being the ability to transfer back memories and experience back to the user when the clone dispel and only con being a very bad headache when the user receive too much memories at once. Using his own innovative brain, Naruto made his own S-Rank Jutsu certified by many shinobis in the village when he used it on them, Oiroke no Jutsu and Harem no Jutsu with the combination of Henge and Kage Bunshin. His mother applauded on his creation.

After a year of hard training, Kushina and Kurumi thought it would be a good time to start his elemental training. They did an elemental affinity test and found Naruto have not one, not two but three elemental affinities. Wind being the strongest, followed by Fire and Lightning both equally strong. Kushina was flabbergasted by the result; it was rare to find a shinobi who has two affinities, much less three with one high level affinity. Moreover, all three affinities were offensive. Minato had wind and lightning affinity while she have wind and fire affinity, she didn't expect him to inheritate all three of them.

While it may be a good thing that Naruto has three affinities but it's practically useless if you can't utilize them. So Kushina introduced him to a completely different training method, the Shadow Clone Training method. For the last year, she stormed up her brain to somehow speed up his training for compensating the time lost when he was asleep. Normally in clans, ninja training starts from the age of six, so she had to somehow recover four-year worth of training; that is why she invented his training method.

With that Naruto's elemental training started, it completely took over the Ninjutsu and control exercise in his daily schedule.

Between these events, Kushina requested Kurumi to send the memories of events that happened when she was asleep, Kurumi didn't saw any harm in it and obliged. After getting the memories, to say Kushina was furious would be understatement of the decade. The look she gave could even send shiver down the spine of Shinigami. However, unfortunately (or fortunately for some villagers) Kushina didn't have an actual body, she just took out her pent up anger on a little Minato shaped dummy made by Naruto in his mindscape. Due to practicing meditation daily Naruto had much better control over his mindscape than before, unfortunately he still was not able to make any major changes until the seal is broken.

During these two years, Naruto also bonded with the giant vixen. They have a friendly bond between them where Kurumi would always tease him about different things and if you ask him, the vixen was just a big pervert with tons of chakra.

Till the end of second year, Naruto could do few C & D Rank Katon and Futon jutsus, some of them would be Fūton: Daitoppa or Katon: Endan and few more. Although Raiton Jutsus were out of their reach, Kushina taught him the basic Raiton chakra manipulation exercises. Raiton was Minato's affinity; she has little to no idea how it works.

At the beginning of his 13th birthday, Kushina deemed him matured enough to start telling him about his heritage from Uzumaki Clan with the exception of the Bloodline limit i.e. the art of sealing aka Fuinjutsu. She explained him how Uzumaki clan was renowned and feared for their Fuinjutsu. She told him tales about her father and ninjas of Uzushiogakure.

From that point Naruto's Fuinjutsu training started with of course his regular Ninjutsu and Taijutsu training. The normal studies time from 3:00 pm to 5:00pm was replace by Fuinjutsu training as Kushina consider him knowledgeable enough, rest he had to gain from pure experience.

Despite being an Uzumaki it took him some time to grasp the concept of fuinjutsu, it was surprising for him when he learned a few drops of ink and chakra can even withhold even the mightiest of beasts. From there he took Fuinjutsu studies very seriously by starting to understand the concept instead of just memorizing it like he was doing before.

Within a year, he learned the basics of fuinjutsu and made Gravity Seals and Restrain Seals with the help of his mother and applied them on his own body to improve his physical strength even further.

During that year Naruto also joined the Shinobi Academy for officially becoming a shinobi. Naruto wanted to show off his skills and ace the exams to make his Kaa-chan proud, but Kushina stopped him. She explained how this would a bad idea; how if he showed his superior skills and abilities, the civil council and elders would try to stop the 'demon' from gaining more power and leaving the village forever.

Naruto understood what she wanted to convey and didn't asked anymore questions. And as such the next two years passed without any special events aside from few more attacks on Naruto, which he was easily able to fend off.

So to summarize everything happened in the past five years, Naruto's shinobi skill improved tremendously. His bond with the giant vixen became almost that of a best friends, if she were a human he would definitely date her. He also reached level 7 fuinjutsu studies. If you don't know, fuinjutsu studies have 10 levels, starting from level 1 that of a novice to level 10 that of a seal master. Kushina is a seal master but no one ever believed her in her days due to her short temper and bashful nature.

And surprising enough when puberty hit him, Kurumi was the one who gave him the "The Talk" or "Birds and Bees". After the talk, due to lack of girls in his real life, Naruto started developing some hidden taboo sexual fantasies toward her Kaa-chan. He would sometime act differently and try to hide his bulge in his pants, which never went unnoticed by Kushina but she would always giggle and shrug it off. Kurumi would always tease him about it for hours in when they had private conversations.

Present (1 Week before Naruto's Birthday)

Mindscape

Naruto yawned lazily, rubbing his eyes occasionally trying to rub off the sleepiness from them. "Kaa-chan why you called me here so early in the morning? I still wanted to sleep some more." Naruto whined, he really was not a morning person but due to training for the last five years, he had to became one…..forcefully. But as they say, old habits die hard.

"Sorry Naru-chan, but what we're going to discuss would be very important plus..ugh…I was also getting bored." Kushina added the last part somewhat nervously.

"What?" the blonde grumbled, still only one eyed open.

"I'm going to tell you about the Uzumaki male Kekkei Genkai." Those words were enough for opening his eyes wide-awake and gaining his full focus, Naruto was waiting for this moment for past years, to awaken his full potential and possibly even free his mother from the cell.

"I told you when you'll be 15, you'll decide if you want to unlock your Kekkei Genkai or not." She repeated receiving a nod from Naruto, "A week from now will be that day, so today I'll reveal almost everything about it and you'll have a complete week to make you decision, okay?" Kushina asked with the most intense expression she could manifest.

"Hai," Naruto agreed, earning a sweet smile.

"Okay, so I would start how it's done in Uzushiogakure by telling its origin." Kushina exhale smoothly, ready to teach some history. "Centuries ago, human didn't have any chakra. You would think it would be a peaceful era if there were no chakra but that's just a big misconception. At that time human used weapons that were more reliable on strengths like sword, spear or even simple Taijutsu. There was a princess named Kaguya Otsutsuki, she could say that she was an alien princess. She came to earth with Shinji, the Divine Tree. The Otsutsuki clan was a race of alien immortals; their only goal was to collect Shinji trees as every planet in which living being resides has their own Shinji tree. Kaguya came to earth with a Shinji tree given to her in case there's any powerful warrior or soldier on earth to resist her. However, fortunately for earth beings Kaguya was few centuries too late. The Shinji of earth was already death and completely dissolved into earth's soil and atmosphere to make what we now call as Nature's chakra." Kushina paused, confirming Naruto was following him and was a little surprised when she found not only Naruto but Kurumi too listening with keen attention. She thought the fox would have the knowledge of this; after all Hagoromo created her, he would have passed the knowledge to them. However, it looks like she was wrong, seems like this knowledge was exclusive to only Uzumaki clan.

Kushina decided to continue the ancient tale, "You can say that Kaguya was the first person on earth to even know the existence of chakra. Every Otsutsuki clan member had their own unique special ability, but they all also had one powerful Kekkei Genkai, its called Protean. This Kekkei Genkai allows the user to copy any special ability of any other Otsutsuki member and keep it, in other words, it allows the user to copy other Kekkei Genkai and keep it permanently like you were born with it."

This information was met with pin drop silence; you could even hear the droplets of water falling from the ceiling to the surface of the cell.

"W-wh-what? Are y-you serious? That has to be a joke, right? That's godlike ability, scratch that, even god will be helpless against something like that." Naruto sputtered, he cannot believe that type of Kekkei Genkai ever existed in this world or even in this entire universe.

"Naru-chan, believe me that ability is actually real and I even have evidence of it." Kushina waited for Naruto's response, when he asked her what evidence, she replied, "The prime evidence would be you and me."

"As for the rest of the story, I would keep it for another time. For now just know that we're descendent of the Rabbit Goddess Kaguya Otsutsuki, though the power she had, may have faded in the track on time." Kushina told him, "Uzumaki clan have two Kekkei Genkai one for each gender. The chains that you saw the first day when we met five years ago is called Adamantine chains, it unlocks automatically when the female have a females chakra reaches a specific density, they are Uzumaki female bloodline limit. As for the male, I'm just going to do that." She explained.

"Oh I almost forgot about the Futanari, you see a natural Futanari born with both the abilities and both of them in their unlocked state." She added, before Naruto could do anything.

"What's a Futanari?" Naruto was perplexed. He never even heard of that term.

"Oh you don't know, I thought Kurumi would have already told you about it, given her perverse nature." Kushina questioned, which was answered by a simple shook of his head in negative.

"I thought it would be better if you explained some of the important parts of yourself and your clan." Kurumi answered, Kushina nodded in thanks.

Kushina shifted her attention back to Naruto, "Naru-chan, Futanari is a third gender who have both genitals, a vagina and a penis."

Naruto nodded in response, until he slowly understand the whole meaning of it.

As she saw the look of realization hit him, she stopped him from asking the question she knew he wanted to ask, "Yea Naru-chan, to be blunt. A Futanari had both a cunt and a dick."

Naruto simply nodded and decided to divert the conversation from the awkward topic, "So, how do I use this Protean?" Naruto asked the million dollar (or ryo, yen?) question.

"This is the very question why Uzumaki clan never revealed this ability. People believe it's a very vulgar ability, some Uzumakis even abandoned their clan name for this." Kushina exhaled loudly, readying herself for the big secret, "For the user to copy a Kekkei Genkai, he/she must have sex with the other person. The user must be on the receiving side of the dick while the other person sends his/her chakra into the user through penis."

Naruto's brain took few second to process all the information given to it, "HHHHAAAAAAHHHH," Finally realization hit him and his reaction was exactly as Kushina thought it would be. "Does that mean I've to have receive a dick in me? But I'm not a female; I don't have even have a vagina." Naruto questioned in shock.

"For Protean to become active and work it isn't necessary to receive the penis from vagina, it can work with either vagina or rectum." Kushina informed. Before Naruto could ask any questions she continues, "If you want to activate Protean you have to take a penis of a futa in your ass and if you ever want to copy someone's Kekkei Genkai you have to repeat the process with that person." She further explained.

"So in short I must have anal sex with a futa to active this awesome Kekkei Genkai of mine and have to do repeatedly with others maybe even strangers to improve it further." Naruto summarized receiving a nod from his mother. He sigh heavily, rubbing his forehead "Man, I was thinking it can't so easy to gain such an awesome power."

"I told you Naruto, this is not some kids' plaything which you can use with much consequence." She added.

Naruto stood on his legs and started walking round and round around the cell; thinking about what his mother just told him. "Say, Kaa-chan? Even if I agreed to unlock Protean, I don't even know any futa in the village and how this will help to break the seal?" he can't see any way to unlock the seal by Protean.

"Okay Naru-chan, I'm going to reveal a secret," Naruto just nodded on that although a little confused, not seeing any point to suddenly change the topic until… "Naruto, I'm a Futanari." She declared.

Naruto's brain had watched better days than today, so many shocking secrets are being revealed today that his brain might just burst due to the overwhelming pressure it keeps getting from her mother.

Naruto thought to ignore the fact her mother was a futa, it's not like she got any chances to choose which gender she want to born as. And asked the question that started bugging him the moment she announced herself as a futa, "But Kaa-chan, isn't it a taboo? You know the relationship between son and mother?" he question, averting his eyes from hers.

"In Uzumaki clan due to Protean, incest relationship is not considered taboo. In fact, it's a kind of a tradition of Uzumaki clan, if a male wants to unlock his Protean it's their mother who help them achieve it." Kushina explained, "And as to how it'll break the seal. I'll tell you when you'll make your decision, on your birthday." She added with her signature sweet smile.

"You've a week to make your decision and if you still want to do it, please also decide till then with whom you want to do it,"

"Huh? Now what does that mean?" Naruto asked with a puzzled expression, there are only two persons inside his mind and one is a giant vixen so it only leaves her mother.

"Huh, I'm hurt kit. How can you forget about me?" The giant vixen named Kurumi asked in mock hurt.

"W-What? There's no way I'm gonna have sex with someone whose even pinky is bigger than me." Naruto shudder at that alone.

"Idiot, where do you get those stupid ideas from?" Kurumi growled, "Unlike my brothers and sister, I have a real human form. How do you think I hide from humans before that damn Uchiha caught me."

"huh now that I think about it, it sound really stupid of me." Naruto admitted with a sheepish look, until he eyes widen 'This is happening so much today, I think I should just keep my eyes wide open the entire day." He thought mentally.

"Wait Kurumi-chan has a human form?" Naruto asked Kushina getting a nod as his answer, "Than why did you hide it for freaking five years?" he asked.

"Well, I just feel like it. Plus if I would have revealed my human form, you would be too distracted by my beauty to concentrate on your training. And mostly because you would had ravaged me like a sex driven beast and steal my chastity." Kurumi finished with fake tears flowing from her eyes.

Naruto just shook his head at her action, 'No one would even believe that a fifteen year old boy could rape mightiest of the Bijuu Kitsune no Kyuubi.' He thought.

"Anyway, since you have to choose in one week, I should show my human form." Kurumi declared and with a small blast, white clouds covered the entire entity. When the cloud cleared, a woman about 5 foot 4 inches was standing instead of the Kyuubi. She have indigo colored hairs flowing till her waist and ears on her head with white fur inside them. She have golden eyes, creamy complexion, round face with three whisker marks on each side of cheeks like her jailer, killer huge E-Cup rack and the most out of the place thing on her would her silvery color nine waving tails and a 13 inches male appendage hanging between her legs. She stood there in all her naked beauty.

Naruto face went from normal to blushing red to pale when he saw her prick size.

"Like what you see?" Kurumi teased with a grin while jiggling her breasts, her voice was now more human.

"GAAAAAAH, please put some clothes on." Naruto shouted and turned his back so he didn't have to see her naked and her huge…..member. He gulped, but it also made him aroused, much to his own confusion.

"Okay, okay, you don't have to shout." Kurumi said now in her more feminine voice, summoned a custom crimson kimono with little yellow design on it, and borders with silver color. She didn't wear any bra or panty because she didn't like it, they are too constricting for her taste. Her kimono did little to much to hide her huge assets. It might even came out from her kimono if she jumped even once.

Kushina stood beside Kurumi and looked straight to Naruto's eyes, "So Naru-chan, we will hear your decision in a week, okay?", he nodded.

"Naruto, before you leave I have another more important part of the Kekkei Genkai to tell you," Kushina said a serious tone," It's about Protean's side effects on you...….."

The rest of the week went as usual, some training, some studying and pranking the village. She spent a lot of time during the week with Kurumi now in her human form. Her teasing increasing using her human body's every part to make him uncomfortable and also about how he'll soon fucking opposite sex. Yeah, a pretty normal week for him.

On 10th of October, they celebrated his birthday in his mindscape. Kushina made him some cake and other dishes in the kitchen made by him. Soon in the afternoon, the time for the decision that can change his life and the plot of this story too.

"So Naruto, what's you thought?" Kushina asked.

"I already made my decision five years ago Kaa-chan, it will not change." Naruto announced with firm tone.

"I see," Kushina smiled, she can clearly see the resolve to do this in his eyes.

"And with whom you want to do it?" Kurumi asked in her lazy tone, already knowing the answer.

"Well, Kaa-chan said that it's an Uzumaki tradition that the male's mother helps them to unlock it, so I'll go with Kaa-chan. Sorry Kurumi-chan." Naruto said with apologetic look.

"Yeah, yeah, go with Kushina. I already knew you would choose her. You're after all mamas' boy." Kurumi did her routine taunting and teasing, causing his to huff.

"Alright, so here the plan Naruto," Kushina started, "It's only a hypothesis but it has eighty percent chances that it'll work."

"There are three ways to open the seal. First, we unlock it with its genuine key, which we do not have; so that option is out. Second, we kill the jailer of the seal; in this case, you Naru-chan, so this option is down even before we think about it. And third and the only option which is safe enough to give it a shot, we use the only weakness of Eight Trigrams Seal." Kushina said with a confident smile.

"Ugh..What's its weakness?"

"Eight Trigrams Seal is one of the best seal for holding a Bijuu. While it can hold even Kyuubi from escaping, it cannot stop someone from outside to enter inside the seal like you Naruto. This weakness is represented by those large vertical bars." She pointed toward the golden vertical bars on the gate blocking their pathway, "Normally other seals created to hold Bijuus have crossbar gates, so neither the jailer nor its prisoner can cross that gate without its key but those seals aren't strong enough and can break or weaken if the jailer suffered from any traumatic experience. Eight Trigrams Seal was designed to overcome that weakness." Kushina went full lecture mode.

"So, which seal you had, Kaa-chan?" Naruto was a little curious.

"Well, I didn't know the name of the seal but I know it was made by Mio-sama, it was very good if you ask me even though it was a crossbar seal." Kushina answered, "Anyway, that's going off topic. So, If we…ugh….get intimated inside the seal and active Protean and due to Kurumi being sealed inside you from the time you're born, you're more familiar to her chakra than me when I was her jailer, it shouldn't take much time to copy Kurumi's chakra."

"But didn't you said, Kurumi's chakra is dangerous if it flow in the body while the seal is in locked state?" Naruto enquired.

"Hai, I said that." Kushina admitted, she liked how Naruto was catching up. "But this is a complete different case, normally when Kurumi forces her chakra in the body of her jailer. The potent chakra cover the body from outside forming a orange color tailed clock, which in turn started damaging the body from outside. While in your case we'll pump in chakra directly inside you and the chakra will not flow through your tenketsu points or pathways." She thoroughly explained.

"Huh…but why would it copy Kurumi-chan's chakra, I thought it copy only Kekkei Genkai, not chakra?" Naruto was totally lost, he was sure he would get a brain hemorrhage till the end of the day.

Kushina was impressed by his perspective skills, "How do you think Protean copy other Kekkei Genkai? Every Kekkei Genkai has one thing in common i.e. chakra. It copies the chakra of the person that the user receives through the penis." That answered his question, so she continues, "The seal has a secondary security system which uses the jailer's chakra on the gate to suppress the prisoner's chakra. And there's also a final line of defense, which activates when both the previous system fails." Kushina said that part with a evil smile, Kushina with a evil smile is never a good sign. "The seal stores a little amount of chakra of the seal maker in its outer layer, just outside of the gate; in our case Minato."

"WHAT!" Naruto exclaimed, he has chakra of that person. The thought alone make him uneasy.

"Calm down Naru-chan. He's asleep like I was, so he doesn't know what's happening." Kushina reassured him he nodded in response. "We're going to use those two security system to open the seal. If my theory is right, when your body copy and replace your old chakra with the copied version of Kurumi's chakra, the secondary system will start applying that chakra on the gate. Due to same chakra inside and outside the gate the seal will possibly go on high alert and assume that the Kyuubi is trying to come out of the seal and has already erase the chakra signature of its jailer completely; which by the way can only be done if Kurumi injects more than fifty percent of her chakra through the gate forcefully. Anyway, back to the topic. As a last resort the seal will active the last line of defense and release the seal maker to reseal the Kyuubi outside the seal." Kushina finished, emphasized on outside.

"But, what'll be the use of it? It's not like he'll open the gate for us." Naruto asked still puzzled, he has to soon increase his training train on fuinjutsu if he ever want to match Kushina on it.

"You're forgetting something Naru-chan, this is your mindscape you have full control over it except inside the seal. So when Minato would appear onside the seal, you should be able to take control of him and steal every knowledge from him plus the key of course." Kushina laid her final plan.

Naruto was applauded by Kushina's brilliance, he was sure he would never be able to create any plan with half of this plan's complexity. "That's a really awesome plan Kaa-chan, but I don't know if it'll be that easy to take control of Minato." He still has his doubts in him.

"Don't worry Naru-chan you'll just have to think of him as an object you created and what you want to do with him. And you'll be able to easily access his memories and take whatever you want." Kushina said, showing full confidence in him. Naruto nodded, if there is one person he does not want to disappoint that would the person in front of him, his Kaa-chan.

!Warning!

Lemon Starts

"So, shall we start Naru-chan?" Kushina asked, as she received a nervous nod by the blonde.

"Don't be nervous, as this is your first time I'll lead after this time you can take charges, okay?" she suggested as she can see Naruto was still somewhat nervous, but from experience she knew once they started he'll automatically start involving.

Kushina took him to the queen size bed made by Naruto for her to sleep and laid him on the bed and slowly came closer to him to initiate a kiss. Naruto closed his eyes and leaned forward, following her lead. Their lips meet and Naruto could not believe the softness and tenderness of her Kaa-chan's lips. Her mother licked his lower lip asking for permission to enter and he happily complied, and thus started a tongue war. Naruto's was sloppy while Kushina's was handling his expertly and submitted his into submission causing him to moan with pleasure. Kushina undid his pants and stroking his cock from over the underwear,

"Ahhh…Ah….Kaa-chan, please keep doing it." Naruto was so engrossed in pleasure that he did not notice when his hand subconsciously started massaging Kushina's erogenous zone from her soft and bouncy breast to her plump rear casing her to jack him off with even greater pace.

"AHHHHH", Naruto finally cum, completely lost in sexual bliss.

"You're such a bad boy Naruto. How can you already cum when your Kaa-chan has not given you permission. You needed to be punished." Kushina said with a predatory grin, slowly her sexual desire took over her. She broke their kiss and watched Naruto panting with a dazed look. She wanted to make Naruto hers, so she tore her and Naruto's clothes exposing her naked goddess like body. There was no bra to cover her massive DD-Cup breast with erect nipples on 1 inch in diameter light pink areola. Only a panty covering her womanhood, although it couldn't hide her already harder than steel 11 inches long rod with a girth of 2 inches and around the glans 2.5 inches, few inches of the head of the penis was already out and visible to Naruto.

Kushina shifted herself, so she was straddling Naruto's chest and tore the last piece of cloth from her "Come on Naruto, suck it. Suck your Kaa-san dry with your virgin mouth." She commanded, a wave a pleasure went through his body hearing her Kaa-chan's commanding tone, he did notice that now her mother was calling him with his full name instead of 'Naru-chan'. He did as she ordered although a bit hesitantly.

"H-hai!" Naruto started with first licking the head of the cock first which was dripping with a small amount of precum, he thought it would taste bitter but 'Wow, it taste like miso soup of ramen, maybe even better'. He loved the taste and engulfed the first 4 inches of hard cock in his warm mouth to get this treat. He swirled his tongue around her cock with bobbing it's head, this earned him an moan of bliss from Kushina. "HAAAA! Naruto, keep doing that. Help your Kaa-chan to feel good."

Naruto had read some of those adult manga in markets on Kurumi's recommendation and he has to say they are very helpful.

Kushina was on cloud nine, she may have had sex and received blowjobs from other women to satisfy herself in past but no one came close to Naruto. It was as if he has natural talent in this, well she would not be surprised if he has more of this talent after all for sometime Uzumaki clan became infamous for their high sexual activities.

Naruto was still trying his hardest to take the whole thing in his mouth but was only able to take 8 inches of the massive prick. Kushina became a little impatient with the lack of attention on the last three inches of her rod, so she got hold of his head and ramp the whole dick inside his mouth. "Come on Naruto, be a man and take the whole thing." She roared.

This caused Naruto's eyes to widen to its limit and gagged, trying to breathe and push out some of the cock out. But he couldn't do anything as Kushina was busy fucking his mouth with a care in the world, "Oh Naruto, your mouth feels so warm and good. I just can't wait to feel your virgin tight ass-pussy."

Naruto's throat was hurting badly due to the sudden deep throating, but he somehow feel even more aroused when her Kaa-chan dominates him. He tried to relax to ease his throat but still gagged few more times, the vibrations of the gags send Kushina to her limit and thrust a final time, "Take it Naruto, drink all the futa cum of your Kaa-chan and tell me how is it. FUCK, here it comes." And with that she started pouring all her baby batter directly inside his stomach. She came for a straight one minute, filling his mouth to brim with her futa semen causing it to overflow, it started coming out from the corner of his mouth, and at the last shot; she yanked her cock and shot the last massive load on his face.

"Awwww Naruto, aren't you looking cute with your Kaa-chan's futa semen covering all your face and coming out from your mouth?" Kushina cooed, the scene alone would make any futa rock hard instantaneously, "How it taste like?" She whispered in his ears huskily and nibbled on it while knitting his nipples with her free hands.

Naruto moaned even more, he does not know why but after drinking Kushina's futa cum his body became even more sensitive. "Ugh…..it tastes….ugh….awesome, please gimme more." He became completely addicted to her semen.

"Ah ha, well it's a specialty of futa cum. Once you taste it, it became like a drug you just can't live without it in you. It also increases the sensitivity of the person who drinks it." Kushina informed with a mischievous glint in her eyes.

The glint alone sends shiver of anticipation in his spines, his cock jumped in excitement.

"Unfortunately Naruto, you have to wait if you want to taste more of your Kaa-chan's yummy futa cum. I never told you but I was waiting for this moment for the last 3 years. Let's go to main event." Kushina denied his request and get off him.

"Now Naruto, on your hand and knees so I can check the filthy anus which I'm going to reshape." Kushina ordered in firm tone.

Naruto complied as her order and quaver in anticipation of what's going to happen to him next, till now everything her Kaa-chan did to him was blissful.

Kushina went behind him and grasp the two round pillow of flesh and squeeze them; checking its firmness, that action earned her a moan as he was still very sensitive due to drinking the futa cum and most probably he be throughout their session. "You really have a nice ass Naruto, soft, round and supple. Just the way I like it." She said the last part with an evil grin and lustful eyes.

Kushina spanked his right ass cheek hard earning a cry of pain from Naruto.

"K-kaa-chan, what are yo-?" But before he could finish, she again spanks him this time on the left ass cheek. Naruto hardly suppressed his moan on that.

"Say Naruto you like being dominated, aren't you?" She asked with another spank on the ass. Every time she spanked one of his bum, his cock would jump in excitement.

Naruto mumbled something under his breath.

"I can't hear what you just said, say it loudly." Kushina again commanded in her authoritative voice.

He couldn't deny it anymore, he loved the way her Kaa-chan dominates her. "H-hai Kaa-chan, I love the way you command me, dominates me, punish me. Please spank me more kaa-chan." Naruto was a little shy to admit the fact before, but the way her mother told him to say the truth, he just couldn't deny it.

"Good boy," Kushina praised, while still spanking him earning cry of ecstasy. He might just cum again if this kept on going, "You know what you're feeling is common in Uzumaki Clan's males, they are born submissive and few of them are even masochist. They just love being dominated, that's why Uzumaki clan was a Matriarchy based clan."

Naruto was too busy in enjoying the sexual pain to register what she said; he was a complete moaning mess and was very close to his orgasm. Kushina noticed it too and stopped slapping his already red and hot ass cheeks, he whimpered due to the loss of pain and denying his release.

"Well what we have here, it looks like my sochi is not only submissive but also a masochist bitch, huh?" Kushina purred into his ears, while caressing his red-hot cheeks and licking them to sooth him before the main course.

Those words caused him to shudder, "H-hai, please dominate me more Kaa-chan."

Kushina smirked, grabbed his bums and spread them, exposing his tight virgin pucker hole. After sucking her index finger making sure it was well lubed, she inserts it in his tight rectum. Naruto gasped when he felt something was invading his anus. Grinning she slide her second and third finger into the already tight ring of muscles.

Naruto groaned in a little pain at her wanton action, "How does it feel slut? Having your mother play with your ass?" Kushina whispered, massaging his anal muscles and slowly stretching them to their limit to prepare him for what would come next.

"Oh, it pains a little but feels so good after sometime, so full." Naruto moaned and groaned in pleasure and pain.

Kushina smirked; stop her stimulations, brought her mouth near his anus and licked. Naruto whined the ministration stopped, but straight went on cloud nine when he felt something like a swishy wet muscle replaced it. When he turned his head, he was greeted with the hot sight of his Kaa-chan licking his tight hole.

"Get Ready Naruto, I'm almost finished with my preparation to reshape you anal hole with my giant mammoth." Kushina told him while lubricating his pucker.

Done with the lubricating, Kushina stood up, spit on her own cock, and uniformly spread it all over. She brought her dick and lined it up with his ass, after rubbing for few seconds on the tight hole she push it and finally penetrated the no longer virgin rectum with only her head of the penis.

Naruto hold his breath and arching his back, he grunted in pain with little to no pleasure. While the ministration was arousing, it did not stretched him as much as her Kaa-chan's 2.5 inches glans.

"Don't worry Naruto, within a few minutes you would be moaning while drooling and forgot about the pain." Kushina reassured, while she was deep driven in her sexual drive, she still didn't want to damage her son permanently, Naruto just nodded to signal him he was ready.

Kushina hold his waist and again started pushing inside him inch by inch. She kept going until 7 inches of her was inside his excessively tight passage and Naruto already was writhing between pain and pleasure though pleasure was winning.

She was having some difficulties with the last 4 inches, so she retreated her cock until only its head was inside and ramped the dick inside the tight bundle of muscles with a massive force. Naruto's eyes to roll backed in his socket and tongue fell out from the mouth and started drooling as her prick went right through rubbing on his prostate. The pleasure was too much for his first time and straight away ejaculated a massive amount of cum his own cock.

"Well someone is enjoying himself too much." Kushina gave a massive grin witnessing her son cumming after only one thrust. She thought to play a little more before executing their plan; she bend over him squishing her rack on his back, leaving love bit on her ways while slapping his still rock hard cock with one hand and playing with his nuts with the other hand and started humping him with agonizing slow pace, rubbing specifically on his prostate. All of this was too much for him and again came a load ton of baby batter, this time on Kushina's hand.

She took her semen strained hand to her mouth and tasted it, it tasted sweet with a little amount of sour. She liked it and wiped cleaned her entire hand by licking. "That was a yummy treat Naruto, hope in the near future I'll get to taste even more of it." She purred in his ears sensually, slowly increasing her ramping speed and also send Kurumi's chakra laced with few of her chakra that she saved for this day.

"Oh fuck Naruto, you ass is so tight." She moaned, now that she was increasing her speed she actually realized how much tight is his anus.

"Oh…ugh….Kaa-chan, something is happening to my testis." Meanwhile Naruto became a semen machine as soon as Kushina started channeling Kurumi and her chakra inside him, he already came almost a liter and didn't show any sign of stopping.

'Must be happening because of Kurumi's chakra.' Even Kushina did not expected this, but she wasn't complained. After all the more he came the more she'll get the delicious treat, so she kept drink as much baby batter she could eat while fucking and sending chakra into Naruto.

"Oh Kami-sama…..Kaa-chan….fuck my ass….fuck it HARDER AND FASTER." He requested, Kushina was waiting to hear those words.

With a renewed vigor, she started hammering him with her now chakra empowered hips and at a much faster speed. Naruto eyes again rolled back, "Fuck Kaa-chan, you're so deep inside me, rubbing by prostate." Naruto said in pleasure between his pants.

"Hai….Naruto, I can tell your outer muscles contracting. You really have a ass of a whore who didn't want the dick to leave it." Kushina growl, she can tell she is very close to her release. She increase the rate of channeling chakra in him.

"Shit, I'm cumming now even at a greater pace. It'll so got to continuously cumming." And true to her words, she was totally reshaping his rectum. He now has his doubts that after this anyone with smaller than her mother's cock size will ever be able to satisfy him.

"Naruto, I'm cumming, fuck, I'm very close…..get ready I'm gonna cum." She warned.

"Hai, please cum inside me Kaa-chan, cum inside me and paint my anal walls white with your heavenly semen." Naruto shouted.

"Here it comes Naruto, here comes your Kaa-chan's futa cum. Don't even dare to let a single drop of it out from your filthy ass or I'm gonna punish him in a way you'll end up with blue balls." She roared, that thought alone send shivers through his spine He definitely didn't want to know what kind of punishment would that me.

She thrust one final time with every bit of her strength and empty herself out inside his tightly clenched butt hole and filled him till brim and beyond, she didn't stop and soon his stomach stated expanding. She came continuously for 5 minutes inside him, when she was finished Naruto looked like a four to five month pregnant man.

Kushina stopped the flow of chakra which in turn caused Naruto's cock to finally pull up his flood gates. She watched his expanded stomach in fascination, before this she never came so much to inflate someone's stomach. 'Mush be an Uzumaki thing.' She shrugged mentally and pulled out her cock from his white strained and ruined rectum with a 'pop' sound.

Lemon Ends

And true to her warning, Naruto did not let even a single drop out from his ass. He fell back on his ass as soon as Kushina pulled her cock out and sighed in content. "That was the best thing I ever experienced *sigh* and now I can really feel a stronger chakra developing inside me." He said opening and closing his fist.

Kushina hugged him from behind and ran her hand over her still inflated stomach, 'I really like your pregnant like state, Naru-chan." She said with her usual sweet smile and kissed his cheek.

Naruto blushed he didn't want to purposefully looked like a pregnant man, "Kaa-chan, it's your fault. You came so much inside me." He accused.

Kushina did a nervous laugh, "Hai, hai, I know. I'm sorry and it look like you like being pregnant or you would have released that load till now." She said with a confident nod.

Naruto sweatdroped, 'Did she forget she was the one who said to not release it?" he sighed and released a bucket load of cum from his sore ass, he would sure be limping tomorrow.

"That was really mesmerizing how your stomach went back to its original size." She said, still looking over his stomach, 'I wonder if my stomach shrank back like that when I was giving birt-" before she could finish her sentence, she was interrupted by a bright shining light coming from Naruto.

Both Kurumi and her have to over their eyes from the light, when the light died down instead of Naruto there was a 5 foot 8 inches girl in her birth suit with shining long blonde hairs in twin tails, violent eyes, three whisker marks on each side of her cheek. Her skin was a light tan endowed with solid D-Cup titties, her arms looks fragile for any heavy lifting work and finishing with sexy long slender legs, hairless slit and firm yet bouncy round ass. In short, the girl looks like she was made for screwing her.

The girl looked around a bit, grabbing her own assets and checking them. "I'm changed into my Naruko form?" the girl asked in her melodic voice
