Naruto Uzumaki Tickled

One day after his lunch with his squad (Squad 7) and Squad 10, Sai was in the library doing more research on human emotions, personalities, feelings and bonds. He had a whole row of books on his table and was reading all of them very diligently.
"I still do not understand this whole 'nickname' thing, but at least the last time I came up with one, the girl did not smack me," Sai thought to himself, "Oh well, I'm sure I will understand it eventually." Sai put down the book and opened up another one.

'Things Friends Do With Each Other' it was called, he looked in side it and started to read. About half way through in a chapter called, Silly Games, he came across a word he didn't know. "I wonder what this word means," he said to himself. He got up and walked over to the bookshelf, got a dictionary and started looking. "T...I...C...K...L...E..., Ah here it is, Tickle, it had many definitions, but when he looked at the other book again, he was able to narrow it down. "I really should learn more of this," he thought.

After a lot of referencing and searching, he finally found an old book, he checked it out, with about a hundred other books and lefts for his home. When he got there he sat in a chair and opened up the book, it told all about tickling, how to tickle, where to tickle and even some tickling justsu. "Hmm, I should find out wether or not that Naruto-kun is ticklish," He thought. He closed the book and left, to go find Naruto. He eventully found him at Ichiraku's Ramen Shop.

When Sai got to Ichiraku's he found Naruto sitting there eating. Sai, walked in and sat down next to Naruto.
"Ah, Sai, how's it going 'gulp',"Naruto asked, still gulping down his ramen.
"Good, Naruto-kun I was just doing a little bit of studying," Sai replied, still wondering if Naruto was ticklish. Naruto was wearing his casual clothes, his, black t-shirt with the Leaf emblem on it, his bright orange pants, a pair of sandals, and of course his headband. "I wonder, where he is ticklish," thought Sai, "The book said that many places were ticklish, but that there were 4 main ticklish spots; the ribs, arm pits, stomach and feet. Now I can't tickle his feet right now, because of his shoes, but maybe his ribs, the 'Friends' book said, a lot of friends poke each other in the sides."
As Sai was thinking all this Naruto was talking to him, when he realized Sai wasn't listening he pushed Sai softly and said, "Come on Sai, you really need to not study so much. Get a life," Naruto said, still gulping down ramen.
"I do not know exactly what that meant, but I believe that that is an insult," Sai replied, poking Naruto in the side.
"HMMM haha HEEY," Naruto said, as he jerked forward, both giggling and coughing, spilling his noodles all over the place. He got up, helped the owner clean the mess, paid and left, leaving Sai, to think about what just happened.
"The book said, that poking him would only produce light snickering and squirming, not that. Naruto-kun must be incredibly ticklish," Sai figured. Sai got up paid and left to find Naruto. He ended up finding him at the bath house.

Sai wandered around town looking for Naruto. He finally found him in the bath house swimming in his orange and green trunks. Sai, slipped off his clothes and stepped in the pool in his dark, gray trunks.
He swam around for awhile and then went up to Naruto and said, "Naruto-kun, why did you lurch forward when I poked you at Ichiraku's?" Sai asked.
"Umm, well, I'm, you see I'm just a little ticklish,"Naruto replied, nervously.
"Aah, I thought so. You see, I just recently learned about tickling," Sai told him, "And I really wanted to learn more."
"That's okay, just keep studying. I'll be going now," Naruto said, leaping from the pool and starting to run. He had gotten about half way to the door when Sai used his new tickle Jutsu, binding him to a tree with his hands over his head and his legs on the ground, ankles tied to the ground, with his toes tied up, leaving his soles taught.

Sai walked over and said, "Well, Naruto-kun, it looks like I am going to get my lesson. I have been learning how and where to tickle."
"NO! Please, please don't tickle me!" Naruto begged.
"Sorry, Naruto-kun, but I really want to learn more," Sai responded. Sai leaned over Naruto, with his finders ready to tickle him and asked, "Naruto-kun, where are you most ticklish?"
"Why would I tell you?" Naruto asked. "If I tell you, you'll tickle me there," Naruto said, glancing nervously towards his feet, his most ticklish spot.
"Well then, I will just have to find out," Sai said.
"NO! DOHOHON'T HAHAHA AAAHAHAHA HIHIHIHI HAHAHA AHAHAHAHAHA HAHA!" Naruto yelled, as Sai dug his fingers into Naruto's ribs and going up into his armpits.
"HAHAHAHA PLEEEEEASE DOOOOON'T TICKLE MEEEEEE! AAAAHAHAHAHAHA!" Naruto screamed.
"Well, those areas are pretty ticklish, let's try a different place. How about that tummy there, is it ticklish?" Sai asked.
"NO! Please don't!" Naruto pleaded.
"Why, is your tummy your most ticklish spot," Sai inquired.
"No, oh alright, I'll answer your questions if, you promise not to tickle me anymore," Naruto said.
"Hmm, I guess, okay, I promise. Now, tell me where you are ticklish in order of how ticklish they are," Sai asked.
"Okay, I'm most, um, ticklish on my f-feet, ESPECIALLY under my uh, toes, followed by my, my stomach, especially in, eh my belly-button, and then my arm-pits, hehe and finally my r-ribs," Naruto replied, nervously.

Unfortunately for Naruto Sai decided to forget his promise and tickle him.
"Thanks for telling then, but I just cannot pass up the opportunity to tickle you, Naruto-kun" Sai said, as he scribbled his fingers all over Naruto's ticklish belly, dipping his finger into Naruto's belly-button every once in awhile, making him shriek and buck.
"NOOOOOO AHAHAHAHA PLLEEEEEEHIHIHIIIIIH AAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH DON'T YOU PROOOOMIIIIIIIIISED HAHAHAHAHAHA AAAHAHAHAHAHAHAHAHAHAAHA! NOOOOOOOOOOOO HIHIHIHIHIHI HAHAHAHAHAA PLEEEESE STOOOOOOOOP!" Naruto screamed through his frantic laughter. His belly was extremely ticklish and every time Sai dipped her finger into Naruto's belly-button, it made Naruto scream with laughter, while bucking and jerking around in his restraints.
"Well Naruto-kun its about time I try tickling your feet," Sai said mischievously.
"NO! Please anything, anything, but that PLEASE!!!!!!" Naruto begged.
"Sorry, but I must," Sai said, as he started move towards Naruto's feet. Sai examined them thoroughly and started poking around his sole while Naruto begged and pleaded for him to stop. He soon stopped experimenting and started to slowly drag his finger up and down Naruto's soles, causing him to squirm and giggle.
"No hohoho hahahah hihihihi aahahahahaha hahahaha," Naruto giggled. Just then Sai went on an all out tickle attack on Naruto's feet, scribbling his nails all over Naruto's arches, sides of his feet and right on his 'Tickle Spot', under his toes. "NOOOOOOO AHAHAHAHAHAHAHAHA HIHIHIHIHIHI HAHAHAHAHAHAHAHAHA AAAAHAHAHAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH! HIHIHIHIHIHI HAHAHAHAHAHAHAHA AAAAAAAAAAAAAAAAAAAAAAAAAAAAH! PLEEEEEASE DOOOOOOOOOOON'T I CAAAN'T TAAAAKE IT PLEEEEEEEEASE! AAAAAAH HAHAHAHAAHAHAHAHAHAHAHAHAAHAHAHAHAHAAAHAAHAAHAH!" Naruto shrieked through his hysterical laughter. Sai, had been paying attention mostly to Naruto's arches, but then decided to tickle under his toes. " AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!" Naruto laughed with insanity.
"Wow you are insanely ticklish," Sai said, as he stopped tickling.
"Yes haha I am ha just don't haha tickle me hihi anymore ha," Naruto said, still giggling.
"I will let you go, but please forgive me, I couldn't stop myself," Sai asked.
"Well, I guess I can forgive you, as long as you never tickle my feet again," Naruto said.
"I will try," Sai promised.
"That's good enough... I guess," Naruto sighed, perking up a second later. "As long as I get to tickle you!"
