Chapter 1: What is Expected of you

"Do you really think this is a good idea? He is going to be fucking pissed when he wakes up." Gray laughed silently walking as quietly as he could into Natsu's bedchambers. Sting fought his laughter knowing he would wake the sleeping prince if he were too loud. "I don't think I can be quiet. I think I have to wait in the hall." Sting was never one for stealth unless he was in a fight.

"I need your help with this. You know his routines as well as I do. The first thing he is going to want to do when he gets up is make his way to the bathroom. We need to make it so when he gets up he has one hell of a surprise. I hope it goes so far that he doesn't make it in time and pisses himself. If he doesn't I am going to feel like we failed." Gray whispered harshly at him knowing he couldn't back out. This little trick had to be intricate. "Besides, we brought the wheel cart with us to make it faster." That was a relief actually. There would be no way that they would be able to put all of the cups and the bucket of flour in the rooms otherwise.

As soon as they made their way into the bathroom they unloaded the large bucket of flour on top of the door balancing it perfectly so it would stay still until the door was pushed frantically open. "Make yourself useful and start putting these cups on the ride side of the room making your way to the bathroom door. I will then help you to the bedroom door. I need to secure this so it falls in the right direction." Sting started to laugh noisily and Gray put his hand over his mouth to keep him from being too loud. "Shh dumbass!" Sting gave him a dirty look, but started to do what he was told anyway.

"Yeah yeah, I understand." Gray watched him as he moved to the right side of the room, placing cup after cup on the floor slowly filling them half way with water. "This is going to take so much time! He is going to wake up well before we are done. Stop dicking around with that damn bucket and help me out you lazy ass!" He continued doing what he was instructed, but he kept looking at Natsu to make sure he wasn't waking up. They would be dead if the Prince woke up before they were finished. They might be his guard, but that didn't mean that he wasn't well trained in a fight.

"Oh stop worrying so much. He is a heavy sleeper; he's not going to wake up until we forcefully wake him. Just do what you were told. I will help you as soon as I know this is going to work in here. It'll only be a moment more. I'm finishing it right now." Once he was done talking he made a victorious sound quietly before walking over to Sting. "Okay lets get this done so we can wake him." They silently created an arrangement that worked well together. Sting would put the cups down and Gray would put water in it. Once they finally made their way to the door they gave each other looks of exhilaration. They looked over the room pleased with their work of art. Natsu's bed was in the center of the room and all around his bed was cups half filled with water. When he woke up and went to get out of bed he would be surrounded by little traps.

"You never did tell me how you were going to wake him." Sting looked over at Gray knowing he had more planned to this prank. Grays smile widened as he grabbed his bag from the bottom tray of the cart that was now pushed outside of the room. Gray was usually the one that woke the sleeping prince, but today would be special. Today was the day that he would finally win their on-going prank war. It started back when they were kids in the castle walls. Gray's dad was head of the army at the time and Natsu took a liking to the small boy that was always hiding away. Gray wasn't allowed to be around for the army and guard training sessions and he wasn't suppose to be too close to the royal family because he didn't hold high enough status so he would hide and stay out of the way. Fortunately for Gray, Natsu didn't follow the rules and decided to be his friend. They've been pretty inseparable ever since.

He thought back to their first prank. The first day he met his best friend. He was hiding in the foyer tucked behind a chair next to a plant so no one would notice him, but Natsu did. He was walking with his mother and their guard. "Mama, I think the plant needs to be outside." Child Natsu looked him dead in the eyes after turning away from his mother. When his mother looked towards the plant and her eyes fell on the small child she knew what her son was doing. He was trying to get the boy to come out and play. "Mama, don't you think that the plant is far too skinny for it's own good. I think we need to feed it."

His mother smiled at him. His kindness was not lost to her. "Well, I think you are right. Why don't you run and get something to feed the handsome little plant. I will stay here and wait for you." Natsu's smile nearly split his face with its wideness and he ran from the room. He was only gone for a moment and Gray was so nervous to see what he would bring him. He was hungry after all. Usually he would not eat all day when he hid like this. "Natsu!" His mother shocked and angry tone didn't register in Gray's ears as Natsu ran over to Gray and shoved mud in his face. Gray was furious and swore that he hated the prince. The declaration made the prince sad and he apologized repeatedly saying that he thought it would be funny and he just wanted to make a friend to play with that was his age and not a guard. Of course Gray accepted his apology after all he knew he was going to be in the castle quite a lot with his father's position and would love to be friends with everyone in.

"I brought some water balloons." I kept them in the bag because I wanted the water in them to stay nice and warm. That will help his daily routine." His memories cleared his mind as he started to pull them out and hand a few to Sting. "You ready?" Sting nodded his head and the fun began.

"Time to get up Natsu!" He screamed loudly and threw a water balloon right in his face. As soon as it smacked him on the forehead it exploded and got everything soaking wet. Natsu's eyes shot open as if he was under attack. He jumped out of his bed and landed on the floor before thinking about his actions or being aware of his surroundings. His feet landed on the paper cups full of water and he fell on his ass.

"What the fuck!" He finally looked over his surroundings and his face went red. Before he could say anything about his situation another water balloon smacked him in the head. "Gray! Sting! I am going to kill you." He went to stand up, again getting pelted with a water balloon, and lost his baring again on another set of cups. "What the hell are in these cups? It can't just be water; it's slippery as hell. Come on guys I gotta pee!" They both laughed at him as he continued falling his way to the bathroom. "I. Hate. You. Two." He finally made it to his bathroom door and pushed it all the way open when the large red bucket of flour fell from it and covered his whole body and the floor with it's white substance. "Seriously. What the fuck?"

At this point he didn't think he could get more upset. That was until a water balloon smacked the back of his head. He let out a growl and went to attack without thinking. He jumped up and went to run to his bedroom door to beat the two to a bloody pulp, but just landed on his face when he met the slick floor again. Sting and Gray were panting on the hallway floor, their faces bright red, and tears rolling down their face from laughter. This worked much better than expected and they couldn't even contain their composures.

"What's so funny morons?" Her voice made their backs rigid and the hair on their bodies stand on edge. There was only one person that could put any one of them in their place and that was the great Titania. She stopped right behind us and stared down at us waiting for us to stand and address her with the respect and honor she deserved. After all she was the Grandmaster. She ruled over us and trained Natsu herself in battle. She looked over us into the room and her face hid her smirk and quiet laughter. She found it funny alright, but for reasons the men didn't understand. "I'm glad that you like to play together. Seeing as you did this together you can clean it up together. Natsu get ready and meet me outside near the training grounds. They will stay behind and make sure this place looks better than when you went to bed. Wont you boys?"

"Yes Ma'am." She walked away and Natsu smirked at us.

"Serves you right dickheads. I will get you back as well I hope you know." The men grumbled in protests as Natsu went back to his bathroom and closed the door to make himself presentable.
