Tsunade was have bad day to start with to say the least. First Shizume had found her sake hiding spot and removed all of it. She also had a medical lesson to teach today. To make things worse Shizume had ordered all the Anbu members to be woman from now on because of a small accident with Tsunade (very drunk) and male Anbu (also drunk) making out. The events that were about to take place were going to turn this day into the weirdest she had ever had.
It was about 9:30 a.m. when Naruto and Kakashi burst into her office nothing she wasn't use to. The thing that made this different was the look on Naruto face it was one of paranoia. "Naruto what is wrong you look like completely terrified?" Tsunade asked with a serious look on her face.
After she asked Naruto seemed to calm down. "Good your not one of them too. I was hoping that you would not be affected." "Naruto, what are you talking about?" "You may want to clear your schedule this will take all of you attention."
Flashback (note she is getting a toned down version)
Naruto was not or most likely never be able to wake up in the morning with out an alarm clock. As it sounded Naruto did his usual reaction to it and pounded it. Now when sat up he noticed that he had morning wood, but that wasn't that unusual for him. He went on with his day without a second thought about it until he was almost done with his shower. He noticed that it hadn't gone away so he thought it would be a pain if he couldn't get it to go down. The only ways he think of was to masturbate or put ice on it to get it to go away. Using ice was something he did not want to put on himself. He had never done it before so he had only Icha Icha novels to go by.
It took him a while to get the pressure and speed right. He could feel himself begin to tighten and he knew that meant he was going to cum. When he finally blew his load, he was surprised at just how much he shot out. After he finished, he began to feel a strange stretching feeling from his penis. Now it didn't hurt but it did feel very uncomfortable. Looking down he saw himself getting longer. If he had to guess he would say that he was a little over 6in (about 16cm) to about 7 and quarter. Now he never heard of anyone getting longer from it if anything he heard the opposite. His thought he would ask the one person he thought he could ask about something like this, Ero-sensei.
After getting dressed and having breakfast, he started to track him down or would have. The problem was the fact that he was being approached by ever woman who wasn't married in view. The women were ones that lived around his neighborhood; all most all of them never even looked at him unless it was to give a hateful glare. After the first one who tried to kiss him, he did the only thing he could think of, run. This made the woman chase after him. The problem was that Naruto got cornered in a dead end with three story buildings on all three sides. While he gathered his chakra the women grabbed him, but he escaped them by having his cloths ripped off. Lucky for him not one of them was a ninja, and Kakashi had been on the roof with him.
"Okay what have you done now Naruto?" the one eyed ninja asked. "Nothing I just got out of my apartment and they all started to flock to me." Kakashi look him over to say that he was not that happy about the way Naruto looked was an understatement. "Okay but can I ask why you are naked and aroused?" Naruto then gave Kakashi a look that said that he wanted to kill him. "The reason behind me being naked is because of the fact that the women down there all grabbed me and tore them off me. But as far as being aroused, I can't get it to go away. I tried leaving it alone and jerking one out but it didn't help." Kakashi thought for a minute before nodding. "Okay here is what we are going to do. First you are going to Henge into a clothed version of you. Then we are going to see the Hokage."
End of flashback
"That is where we are now," Naruto stated. "If that is true then, why am I not effected like those women?" Tsunade ask. She thought she had him there when Kakashi spoke up. "I was actually watching Naruto before he saw me so I think I know why you aren't affected. The woman had two things in common and that was they single and young enough to have children." That statement made sense since she was too old to have children. The one thing that did bother her was the unmarried thing. "I can understand that, but how are the woman that are married unaffected by him." They all thought for a minute that was the only thing that didn't add up. "I may not understand this fully but when a woman is in love, don't some hormones do odd things to their system." Both Kakashi and Tsunade looked at Naruto for a minute. Both could not understand how he knew that fact.
"Let's get back to the subject at hand shall we," Tsunade said. "If Naruto steps out his door he will be mobbed by women, so he must be confined to his apartment. The only problem is that we have no idea how long that will be for or what is wrong with his … member. So Kakashi and I will see if there is anything in the library that will give us any clue to ether problem. Naruto your orders are to stay in this office until we return. You are also to talk to the Kyuubi to see if you can find out anything from him."
Before he could say anything the two of them had left the office. "Fine it's not like I have a choice." Sitting on the floor and beginning to meditate. When he entered the mindscape it looked like it always did like a dank sewer. Following his memories to the Kyuubi's cell, he noticed it was quite. When listened for a while he found he did hear the Kyuubi breathing and thought he was asleep. "HEY WAKE UP!!!!" After saying that he saw a pair of half closed red eyes. "Why did you wake me brat?""Because I need some answers as far as what is going on?" "Why are you asking me instead of that woman with big tits?" "Because you are the only one who could have done this to me and I already talked to her. She said to ask you since nothing like this happens to humans." "What has transpired while slept?" Naruto tells the Kyuubi all that has happen since he woke up. "I do know why the women are trying to sleep with you but not what is wrong with that thing you call a penis. What is happening to you is something that only happens to us bestial demons. It is called Lusting Aura. It makes any female that doesn't have a mate and is capable of having your young attracted to like a moth to a flame. The time it lasts will not be more then a few days." "I guess that some of your demon types are rather hard to find." "You are right but in my case I did need to use that aura to get a female. When you are a demon lord they seek you out." "Then what is going on with my member? It has started to grow but why when I climax?" "Hhhmm… Ah I get it now. The reason your 'member' is growing is that it is getting a larger then normal amounts of demon chakra released when you climax. When you aren't playing with yourself it is just giving you as enough for what you call it a 'hard on'." "Wait does that mean that I will get to big for human women?" "No you humans have your limits as far growing. That doesn't mean that your whole body will not grow once your 'member' is finished." "What do you mean my body will grow more I am twenty years old. Humans over that don't have growth spurts." "You know that as a child, people of that orphanage would starve you in hopes you would die. Well that effected your growth, but we demon grow more based on our type. Like how I grow each time I gained a tail. You on the other hand did not get enough to eat as a child so you can still grow with the demon chakra I give off." "Okay then why didn't I grown when I used your power willingly?" "The power damaged you body too much and was split for fighting and healing." "If that is true then won't I need to eat a lot to restore the missing nutrition?" "Yes you will but the demon energy will make up for the lack there of until you can full you ramen loving gut." Just as the Kyuubi finished talking the sewer shock violently and continued to slowly rock. "What is going on?" "It would seem that another female has found you and she is riding you like a horse." "What, who is it?" "You know her so there shouldn't be a problem as far as once this whole thing is over. At least go and enjoy it brat." The Kyuubi then sent Naruto back out to his mind to the world outside. "I wonder should I have told him that his fertility increases dramatically after the aura takes effect."
