(This involves all of the teams in Konaha and a team from Suna. This takes place during the filler arch of Naruto, before he leaves with Jiraya. Enjoy)
Naruto, Sasuke, and Sakura were waiting for their teacher at the training grounds like always. He was at least an hour late already. They were about to leave when he appeared in a tree.
"Ohayo."
"YOUR REALLY LATE THIS TIME!" Kakashi tried to calm them down.
"Listen, I actually have an excuse this time. I was getting us reservations." He saw a look of confusion on their faces, "I got us reservations to the Blue Harbor Resort and water park in the land of the mist." All of a sudden he saw Naruto flying through the air and collide into him, knocking him out of the tree.
"YYYEEEEAAAAHHH!" Sasuke just shrugged his shoulders and closed his eyes while folding his arms.
"I'm not going." Said Sasuke. Kakashi just looked at him and smiled. He patted the boy on the head.
"Now listen here. The Hokage agreed to pay for this trip. It was very expensive. If you don't go, not only will it show complete disrespect towards the Hokage's good will, but I will kick you so hard in the balls I will create a vagina. Now do you see where I'm coming from?" Kakashi says all this while still smiling but Sasuke knew that his teacher definitely meant it. He didn't even want to think about how it would feel.
"Alright, I'll go." Sakura squealed with joy. Kakashi stood up.
"Great, the bus will pick us up tomorrow. Gai and some other teams are coming as well. Gaara, Kankuro, and Temari will be there as well." Naruto tried to think of Gaara in a swimsuit at a water park. He couldn't. Gaara always kept to himself and he had never seen Gaara even wear shorts, let alone a swim suit, "Better pack for a week or so." Naruto quickly began to run home and he was at his house in minutes. Sakura skipped home along the water to her house and Sasuke slowly began to walk home. Kakashi disappeared to wherever he lived.
Naruto packed a bunch of his orange suits and his favorite orange bathing suit. He packed all of the essentials and he put as much money as possible into his frog wallet. The sun was setting and he made himself some ramen. After dinner, he got into his PJ's and penguin cap and fell asleep.
(The next morning)
Naruto wakes up and is exhilarated. He puts on his clothes, throws his PJ's into the bag and runs out the door. He finds everyone waiting for him at the gate. There were a lot of people. After about 30 minutes of waiting, the buses arrived and everyone piled in. Naruto shoved Lee aside and sat his butt next to Sakura, who was hoping for Sasuke. Gaara sat in the back with his own seat. When everyone was in a seat, the buses were off.
(Sorry if it's short. I just need to get the story going. There will be much more to come.)
