The Secrets of the Akimichi

"Hey, I think I finally got the hang of it!" I said, looking up and grinning proudly.

After my initial meeting with Tsunade, I was mostly left alone to rest and recover for two days. On the third day, Tsunade came back with Shizune, announcing that she had deciphered the slab found in the Akimichi household and was ready to share it information and ordered me to come with her to this secluded grassy knoll, which was surrounded by a ring of forest and small waterfalls. Ever since we got here however, instead of revealing information, Tsunade seemed more interested in making me do a bunch of exercises, mostly on how to keep my balance and walk with an expanded cock. Burning with curiosity I am, I didn't try to press my luck, partially because Tsunade Senju is not a woman to mess around with and partially because I liked the idea of walking around with a massive cock in front of the strongest woman in the world and her assistant and seeing the way they react.

"See! I got it now!" I said walking over to the ladies, who were sitting at the foot of a waterfall. Walking with a cock that goes past my knees was a challenge, but with some attention and practice, I was able to do it, and I walked right in front of the Hokage but stopped three feet in front of her. While I'd like to have gone a lot more, I wouldn't dare. Shizune may have been throwing not so subtle looks at my cock for an hour now, but Tsunade seemed to just be angry at the situation she has been **** to deal with.

"Very well," Tsunade said with **** patience, pretending as if all of this was normal. "Now practice running."

"Oh man! But I really-"

"You said you wanted to learn about what it says on the stone, and I deem that this activity is necessary for you to do before that! If you don't want to, you can leave!"

I scowled, but there really isn't much one can do against an angry Hokage, so I started practicing running around with my expanded cock. Immediately I started tripping over it. At least, there isn't anyone else to witness my humiliation, I thought. The woods around me were made by the first Hokage himself, as a private sanctuary for himself and his successors. Only the Hokage and people they personally invite are allowed in. The ANBU guarded the outer forest, but they too weren't allowed in without express permission.

While I might have thought that this whole ordeal was humiliating, it had the opposite effect on the ladies.

"Dammit Shizune!" Tsunade whispered to her closest friend and confidant in a voice low enough for the boy to not hear. "How many times do I have to command you to stop rubbing your legs together!"

Shizune huffed in annoyance but stopped, doing her best to ignore the tingly feeling in her... below area. "Come on, Lady Tsunade," she whispered back. "Does the sight of that really not do anything for you?"

The Lady Tsunade glanced at the girthy, abnormally large cock swinging between Choji's meaty thighs, and gave a very un-lady like grunt.

After another half an hour of me trying to figure out how to run with a cock that dangles past my knees, Tsunade's patience ran out and she called to me, even though I still needed more practice. Guess the Hokage has better things to do rather than looking at a naked teenager run all day.

"Sit down, Choji," Tsunade said, gesturing at a nearby tree stump. "It is time for me to disclose what I learned from that stone found at your house."

"Awesome!" I grinned eagerly, sitting down in front of Tsunade.

"So, the stone... it talks about a secret jutsu, one that is unique to the Akimichi clan. The partial expansion you achieved," Tsunade said, vaguely gesturing at my crotch without trying to look at it, "is just the first step in it."

"So, what does it do?" I asked eagerly. This might be my big break, the chance to do something big (no pun intended) in this new world.

"Answering that is the more difficult part," the Hokage replied. "The runes on the stone are quite old, and it's written in an older form. More poetic rhyming than anything clear and precise. Even without that, the focus seemed to be on how to do the jutsu rather than what it does. The feeling I got from reading this is that this hidden Akimichi jutsu was once popular enough that whoever wrote it didn't feel a need to explain what the jutsu does, as that would be seen as common knowledge."

"Oh."

"We do have some clues on what it does, however. For example, we know that whatever this jutsu produces have near miraculous healing properties."

Well, that explains Tsunade's heavy interest in this. She's all about expanding the borders of medical ninjutsu.

"Also," Tsunade continued, "we know that it is used in offensive capacities. Again, the particulars of it are frustratingly left out, but we know that this was the great power of the Akimichi. Due to the large amount of chakra it consumes, an Akimichi can only do this once a time, but apparently that's enough. The stone mentions entire battles being won decisively with one use of this jutsu. Apparently, it was good enough for the Akimichi to go toe to toe with the likes of the Uchiha and the Senju and come put on top," the way she said it implied that she clearly didn't believe this last feat, and maybe all of the rest too, but I have heard enough.

"Well, let's do it!" I exclaimed, jumping excitedly from the stump. "That's why you had me practice first, right, Lady Hokage? You want to see what this secret jutsu does as well! So, let's do it!"

"It isn't as easy as that Choji. There are... dangers associated with this kind of jutsus." Tsunade said in a voice so grave it dampened my own excitement a bit and made me sit down again.

"What kind of dangers?"

"The stone explains them well enough. Actually, most of it was dedicated to explaining why the Akimichi stopped using this jutsu. Apparently, it made them too powerful.

"What's wrong with that?" I asked, bewildered. "Isn't being too powerful literally the goal of every ninja?"

"It's more complicated when it's an entire clan, Choji," Tsunade explained. "Generation after generation of strength and dominance rub the other clans the wrong way, and then they ally together to plot your own downfall. Clans that get too powerful have a history of being wiped off the map. Think of the Uzumaki. Or the Uchiha. And while the fate of my clan was far less tragic, I'm sure that you are well aware of me being the last Senju. That is what the Akimichi feared. The person who wrote this stone, a head of the Akimichi some centuries ago began to hear whispers of such plots against his own clan. After discussing with the elders, they decided to stop using this jutsu and even agreed to never teach it to the next generation. Akimichi became an ordinary, mid ranking clan, and the only existence of their former prowess is this stone slab, made just in case that the Akimichi were threatened with annihilation even after they collectively agreed to stop using their most powerful jutsu. But that never happened, and memory of it faded into history. At least, that's the narrative that I was able to build from the little clues I could find in the slab. So Choji," Tsunade stared at me squarely with her brown eyes. "Are you really ready to try this jutsu. Are you really ready to being this jutsu that nearly brought your clan to extinction back into the light of the world?"

For the next few seconds, the only sound was that of chirping birds, as I thought of my answer. "Yes," I said confidently, meeting the Hokage's gaze. "Yes. We are in a different time now. It's not just one clan going after other. The Akimichi have the backing of the Konoha. And we know that something bad is coming, maybe a war. If this jutsu will help Konoha in the wars to come, if it's healing powers will help save the lives of others, then I think we should use it. And, anyway, I'm not saying we go out with this jutsu to the rest of the world right away. We'll have to see what it does first. Then, it's your job as the Hokage to see if it's use will be beneficial for the village.

After staring at me for a while, Tsunade smiled. "That is a very responsible answer Choji. And I agree. We should at least try it out first.

"But I do have a request," I said. "If this will put the Akimichi in danger, can you keep the knowledge between the three of us? At least for now. I don't want anyone in danger because of my actions, especially not those of my own clan."

Tsunade nodded. "Very well."

"Ok, then," I said, standing up and rubbing my hands, some of the old excitement coming back to me. "Let's do it then! What am I supposed to do next?"

"Well, the first step is the partial expansion," Tsunade said slowly.

"Already done!" I chirped, pointing at my monstrous cock.

"Yes, I can see that," the Hokage said drily, before putting a hand to her forehead. "The next step is even more embarrassing. You will have to get, ah - erect."

"What?"

"I don't know alright!" Tsunade snapped, blushing herself. "It's just the second step on the slab! You said that you wanted to try this thing, right? Well, get hard then!"

"I can't get hard on command!" I protested. "Especially not when you are glaring at me like that!"

"Well think of something that excites you!" Tsunade snapped back, her cheeks getting rosier by the second.

"That's not enough. I'll need... visual encouragement!"

"Visual - I hope you are not saying what I think you are saying! I'm still you are damn Hokage!"

"Who asked me to pop a boner in front of her!"

"To help you learn!"

Shizune coughed before I could retort. "Forgive me, Lady Tsunade, but I don't think this bickering is helping anyone. And if Choji wants visual stimulation, then I'll be more than happy to provide it to him."

Tsunade huffed as she crossed her arms underneath her bountiful chest. She did not like how quickly the boundaries of professionalism are being demolished here, but what can she do? Being hard seemed to be a pivotal part of this jutsu. She spat out a **** word through gritted teeth. "Fine!"

Shizune got to her feet triumphantly and flashed a smile at me. I always thought of her as pretty in a 'nice, older sister' kinda way, but now every movement of her was imbued with a sultriness that I would not expect of a woman like her. "Have you ever seen a girl without clothes, Choji?"

Throat dry, I simply shook my head.

Shizune's teeth flashed at me. "Good. You'll get to start with a proper woman, then."

"Don't tease the boy and get on with it," Tsunade huffed.

Wordlessly, Shizune untied the white obi that was tied around her waist. Her dark blue kimono came off, first one shoulder, then another, then the whole thing rushing to the ground and pooling around her feet. Shizune delicately stepped out of her clothes. The simple white underwear she wore quickly followed. "Well? What do you think?"

I was enchanted. While much of my attention so far has been bestowed upon, rightfully, Tsunade, I realized now that I have missed out on Shizune. I would have expect at least some scars from a ninja's body, but apparently, I have underestimated medical ninjutsu. Shizune's skin gleamed as white and flawless as porcelain, with the only sign of her being a kunoichi being her taut, athletic body. Breasts the size of apples stood proudly, with brown nipples topping them off. A small amount of black hair, wild yet orderly, stood on her cunt. Confident of my eyes on her body, Shizune turned her back to me, showing off her shapely buttocks, and bent down to pick up her clothes. She stood up and began to fold her clothes neatly as if this was all perfectly normal.

"You didn't have to do all that," Tsunade grunted. "The boy was hard the moment your breasts were out."

I looked down and realized that I was, indeed, hard. My cock, now erect, was nearly the size of my legs. It was obscene, long and girthy, pulsing like a beast.

"I just wanted to get the best results possible, Lady Tsunade," Shizune said cheekily. "And I believe I did so!"

Tsunade huffed, half amused, half troubled, before turning to me and telling me what I am supposed to do next, the signs that I have to make with my hands and the words that I am supposed to say. Then she pointed to a tree, where a set of concentric rings were roughly carved on the tree trunk with a kunai. A target for me to shoot at.

"Are you ready, Choji?" Tsunade asked.

"I - I think so."

"Remember the signs and the words?"

"Yes."

"Then do it!"

I gathered up my confidence and my chakra. "Partial Expansion Jutsu; Release!"

For a second, nothing happened. Then I felt it. Energy building up in my body, a roaring, tsunami like feeling in my body, all of which focused on the tip of my cock. Then I cummed. I felt lightheaded and lost track of time, but I cummed and cummed, wave after wave of white liquid shooting out of my dick in an unexpected speed.

I stared at the sky, taking deep breaths and trying to get my spinning head under control. Then I looked down. The target that I was supposed to hit was utterly submerged, along with the entire lower side of the tree. Streaks of cum were now running down the tree and began to pool around its trunk, to the point that the tree looked like it grew out of a small, white pond.

"Is that it?" Tsunade asked incredulously.

"What do you mean is that it?" Shizune marveled. "That's enough cum to fill a tub!"

"Oh, well, yes. Quantity was its quite impressive. But that was described in the stone like it was some ultimate attack! I was expecting the tree to be uprooted, at least."

A moment of silence followed. I was simply too relieved and lightheaded to answer.

"Maybe its offensive capabilities are more subtle than that," Shizune mused. "Maybe Choji needed more stimulation. Maybe he just needs more practice."

"Maybe," Tsunade conceded. "I don't think it's wise to do any further experiments today. But we can at least test the... ejaculation for it's supposed healing properties."

"I'll collect the samples!" Shizune chirped, rising to her feet.

"No! I'll do it myself!" Tsunade said, walking to the tree. She hated being so strict with Shizune, but the girl is dealing with all of this far too easily. It's better that for now, she herself dealt with this matter.

Tsunade walked under the tree carefully and saw a single drop of cum beading at the edge of a leaf like a drop of dew. She waited patiently, and when it fell, she used the speed of a Sanin to catch it in a test tube, without having any of it touch her skin. Putting a cork on it with care, Tsunade tucked the test tube inside her green robes.

Tsunade looked back to see her naked assistant and the impossibly hung teenager. The cum she now in her position might not have been the destructive weapon she imagined, but it was clear that it already changed somethings within those two. Whatever it might be, she will get to the bottom of it. She was, after all, the greatest medical mind in the world. And the Hokage. No gallon of cum will outdo her.
