An idea that I wanted to see in a fic for a long time. Now here it is. In case you're wondering this take place after Naruto's 2 year training trip when he gets back from his little run in with Sasuke for the first time in years.

Chapter 1

In Tsunade's office.

The village's good old beautiful 5th hokage was in her office leaning back in her sigh with a peaceful look on her face.

She had just completed all the paperwork she needed to do today in no time flat. Now she was free to have the rest of the day to herself. Which isn't rare for her, not since she took the title of hokage.

"I wonder what to do now?" she asked herself. She rubbed her chin in thought. Then she stood up outta of her chair and stretch out her muscles. "Maybe I'll try my luck at the-"

Before she could finish, the door suddenly swing open to reveal, the hokage's assistant herself, Shizune, in her normal assistant attired. She was breathing hardly, a sign that she ran here as fast as she could.

"Lady Hokage!? We need you at the hospital!" Shizune breathed out.

"Shizune? Why? What's wrong?" the hokage asked.

Catching her breath, Shizue stood up to look at Tsunade with wide eyes.

"It...It's Naruto!"

Leaf Village Hospital.

Both Tsunade and Shizune walked down the halls of the village local hospital. Tsunade was looking at a clipboard in her hand with various test results on it.

"I see. So there really no way to fix him?" the blonde asked looking back at her assistant.

"No the jutsu used on him is very specific. It is linked right to his chakra system and well go off from the slightest sense of overused." Shizune explained.

Tsunade grit her teeth. "And I guess it doesn't help that he's also certain a tail beast doesn't?" she asked only for Shizune to shake her head.

"No it doesn't. In fact it only makes it harder for him to control how much chakra is use."

They suddenly stop in front of a white door that leads to room. The door had a sign that reads, Uzumaki.

Shizune looked at her boss with worried eyes. "What do we do now?" she asked.

Tsunade sighed. She knew what had to be done in order to keep Naruto and everyone else alive. She had seen it before in her days of being a ninja. But could it really work this time as well?

There was only one way to find out.

"I heard of this before, and I only know one thing to do that will keep the village and Naruto safe." she then turn to Shizune. "Go info Kakashi that Naruto will be able to go out on more missions by tomorrow but don't let him know about his 'condition'. I need to have a talk with Naruto for a moment."

Shizune was curious as to what Tsunade had planned but decided to follow her orders and bowed before walking away until Tsunade voice stop her again.

"And tell Anko to meet me in my office in one hour." with that being said Shizune walked off to her duties.

After taking one moment to steel her nerves for what she was about to do. Tsunade turn the handle to open the door.

In Naruto's hospital room.

"Soooo bored!" Naruto half groaned, half yelled out loud to himself.

He was in his hospital room in the bed laying on his back staring at the ceiling with nothing to do. He had woke up about 40 minutes ago already in the hospital. The doctor told him he was knocked out during a mission with Kakashi, Sakura, and Sai. But he doesn't remember much about it. Just that they were going out to find out about this group of ninja attacking other people on road.

And that's about it. When he came too Shizune was the only ones by his side. Well, besides a doctor and a few nurses. Shizune had told Naruto that everything was fine and that he only been here for 2 hours but she wanted him to stay a while longer.

Apparently the Hokage wanted to speak to him. She then left to attend to other matters, but Naruto couldn't help but notice her staring at him weirdly.

So for the time being he had been laying here for the pass half an hour in just his normal black t-shirt and green boxers. Though for some reason he find out that he has some kind of blue watch on his left waist. But it didn't tell the time and had the number 80 on it.

Shizune had left before he had a chance to asked about it. He also had this really weird feeling in his lower belly and crotch. It almost felt….warm. And was getting warmer as time passes.

The sound of his room door opening knocked him out of his thoughts and made him sit up straight to look at the 5th entering his room.

"Granny Tsunade!" he exclaim, very happy to see her again in her everyday attire. Said woman had to resist the urge to yell at the boy for calling her grandnny. Even to this day it still gets under her skin.

But she had other important things she needed to get to with him. So with her good judgment she simply waved at him and pulled up a chair next to his bed.

"Naruto, still lively as always I see. How are you feeling?" she asked as she sat down. She tucked the clipboard she came in with under her arm.

Naruto rubbed the back of his head. "Oh pretty fine. Just getting through another day of being a ninja." he joked.

The hokage was sort of relive to hear that. She was worried that he might be in some kind of consist pain. "So everything feels normal?"

Naruto nodded his head. "Yep pretty normal right now. Hey! Does that mean I can go now?" he asked excitedly like he was about to jump right out of the window as soon as she said yes.

Unfortunately she shock her head no and answered, "Not yet." she then took out the clipboard she had under her arm. Which causes her breasts to jiggle a little.

"Now tell me, do you remember anything?" Tsunade asked staring at the board.

Naruto crossed his arms and began to think really hard. "Uhhh, I remember being out on a mission, fighting some bandits, and getting knocked out."

"Is that all?" Tsunade asked. Naruto nodded to which Tsunade looked up at the boy. Which a look that he hadn't seen before.

"Naruto." she started firmly, trying get the boy full attention. Noticing the tone of her voice the teen look fully at her to see what was wrong.

"Do you know how you got knocked out?" she asked. The blond teen shuck his head. "No not at all." he answered.

The hokage took a deep breath before continuing then looked him right at his face. "You were hit with a, unique jutsu." she stated. Naruto title his head at that. "Eh?"

Tsunade already knew it wasn't gonna be that easy. "During the mission you were attack by a group of rogue ninja." she waited to make sure he was following, which he did when he nod.

"Yeah I do remember that." Naruto admitted. Recalling bit by bit of the mission. "They were doing something like attacking markets and trade stuff right? And they were wearing red capes over themselves."

Tsunade nodded. "Yes these ninja were part of large organization. One that has becoming a problem for the leaf village. Apparently they started attacking our supply routes and destroying them about a month ago. We been trying to find their base but still nothing on it."

Naruto put his hands behind his head while commenting, "These guys sound like trouble." he then went wide eyed as a question pop up in his head. "Wait. What does that have to do with me?"

Tsunade went quite all of the suddenly for while. Before he had a chance to ask what's wrong she finally said. "During the battle one of the ninja, hey dying moments, went up and used a jutsu on you. A kind that mostly used during life threatening missions as a last final resort." she went quiet before speaking again. " A human bomb jutsu."

Naruto slightly tilt his head to side, making Tsunade sighed at the denseness of himself. "You have a bomb in you Naruto." she said bluntly.

"Ohhh! I get now." Naruto said. They waited a few more seconds. "WAIT WHAT!"

Naruto jump up on the bed and began to put his hands all over himself, checking for anything out of place on him. "It's not on you. It's in you." Tsunade said and of course Naruto responded in the only possible. "WELL GET IT THE HELL OUT!"

Tsunade sighed. "If we could we would have done it already. But as I said, it's an unique. It's embedded in your chakra network system and it won't be remove unless the caster of the jutsu remove it themselves." Tsunade then looked away from Naruto for a moment. "But the caster died during the fight." she said quietly but loud enough for Naruto to hear.

When he did he immediately turn blue in the face and fell down on his hands and knees on the bed. His head now slouch down in defeat. "So there's no hope for me? I'm nothing but a bomb?" he said sadly, almost on the brink of tears. Until Tsunade spoke up. "Well not yet actually. There's still a way to not have you explode and take half of the village with you."

This made Naruto sit up straight and look at her with hope in his eyes. "Wait really!"

Tsunade clear her throat. "Yes. You see your still here right?" Naruto nodded to her question. "You see because this jutsu is in your chakra network, it must need your chakra to power it up so that it well go off." Tsunade made sure he was paying attention to her words, which he was when he was nodding to her every word.

She continued. "So as long as you don't use too much chakra it won't blow."

Naruto was about to jump for joy hearing that, but Tsunade stop him by saying. "Unfortunately, since it embedded in your network, which has chakra flowing through it daily, it still getting charged no matter what."

Naruto was about to go into his depressed stance again. "But." Tsunade said stopping that from happening. "We can keep it from every going off even with it getting charged all the time."

"But how do we do that." Naruto asked. Tsunade put down the clipboard and took off her green jacket. "Uhh, Granny?"

She then put a finger to his forehead and whisper something under her breath. In a few seconds, Naruto then felt parts of his body went limp and fell down on his back on the bed.

"Hey! What the heck!" Naruto begin to try to move but found he couldn't. Not even one of his fingers.

"It's okay Naruto." said Tsunade. She began to lift his body and made his position more comfortable for him by setting his head on the pillow. "I use a limb restraint jutsu to keep you from using your arms and feet."

"Why!" Naruto basically shouted. A little annoyed by it all.

"So you'll be easier to deal with by not trying to resist anything I'm about to do." she answered. "Now to keep the bomb in you from blowing up, we need to keep it from getting fully charged from your chakra and to do that every once in awhile when the bomb in you is getting close to setting off. We need to have you let out some chakra." she explained.

So far Naruto was still kinda following. "So how do we do that?" he asked. He notice that she was also on bed and actually moving closer to him in fact. Stopping near his lap with his legs spread out. He had a pretty nice view of her cleavage from the angle his head was tilt at.

"By doing this." she then suddenly reach for his green boxers and pulled them down. Exposing his limp 4 inch member. Still cover in foreskin apparently.

"Hey! What the fuck!" Naruto screamed out loud in shock. Even more when one of her hands went down to grab the base of his penis.

"Calm down Naruto. This is the only way for the body to release chakra." she then gently rubbed her hand up and down. "We have to get you to cum." she said.

Naruto face was pure red right now. This was the first time anyone, beside himself, has ever touch him down there. "I-I can just rub one out." he said. Trying to ignore the new feeling in his penis.

Tsunade look up the boy while still trying to jeck him off. "That won't work I'm afraid." she noticed that his cock felt oddly warm for some reason. "Must be the jutsu in him building up power to be let out." she thought.

Tsunade then goes to explain. "When two ninja of opposite genders have sex, they both let out some of their chakra when at a level of sexual release. So that way the child they will have will have both kinds of the parents chakra in its system."

As she's talking Naruto begin to get hard, his dick going from a limp 4 inches to a hard 6, with a width of 2. His cock was pretty much burning at this point. Tsunade blushed at the heat coming off it.

"Good I feel the chakra from jutsu redirecting to here. Now we need to making it come out." she then put both hands on each side of his penis and started to give him a handjob as best she could. Rubbing her hands fast and hard, making the boy's head go dizzy as he let it fall back on the pillow while he moaned at the good feeling he was receiving.

Some clear liquid begin to come out of the tip of Naruto's mushroom like tip. As it slide down his length it made for a great lupe of sorts, allowing Tsunade to go faster. The hokage drop a hand down to his balls to cup them. They felt quite full and were of average size.

"Well at least he's healthy." she thought. Her face a little flush and red. It's been a long time since she have touch another man. It was very embarrassing since it was doing such things to 16 old boy, but she knew she HAD to do this or else Naruto could risk losing his life.

And she was not gonna let that happen.

Naruto, after stopping all type of resistance, was laying his head down as he watch Tsunade jerk him off. This was still a very surprising event he was in. A beautiful lady, sitting on top of him, playing with his penis, trying to get him to blow his load. This was just like some of the dreams he had. But instead of Sakura it was Tsunade. He didn't mind though, not with the view of the busty lady's cleavage hanging around in her shirt for him to see.

After about 8 minutes later of tending to Naruto. The young virgin felt the burning feeling from earlier grow to the point where it felt something bout to come out. "Granny I'm-" Tsunade already knew what was going to happen. When she felt his dick twitching under her hands she went faster while yelling out. "Shoot it out Naruto! Get every single drop out!"

Soon she saw a rope of thick white goo shot out of Naruto's cock, reaching to hit her chin. A more shot out one at a time. She was amazed at how much the boy could produce, some got on her chest and shirt. But she was also taking back at the color. While most men sperm was just white. Naruto's, for some reason, was white with a tint of orange in it.

"I wonder if it's the jutsu place in him. Either that or the nine tails is doing something." Tsunade looked on as thoughts begin to run through her mind. "I better bring a supply of this to be study on."

She look up to see that Naruto had gone to sleep after ejaculating all that cum. She also notice that the watch on his wrist now had 10 on it instead of a 80 which was close to it being at 100. Which is when the bomb would go off if it reach that number.

Seeing that her work was done she headed to the door and left him there to sleep.

For the next day he'll be returning back to his normal duty as a ninja.

But now he needed a little more care.

To be continued.
