Title: Brothers, Body Paint And Too Much Butterbeer.
Author: Chibi Zen-chan
Rating: PG for now. Will indefiantely be R.
Pairing: Fred/George
Notes: Okay, after much boredness, I'm writing the first chapter... 5 minutes after I wrote the prologue.
Disclaimer: Fred and George aren't mine. But I promise to put them back when I'm done playing with them. ^-^ The strange girl is mine, though.

After much discussion, and buying of more joke fireworks, the twins set off home. Muttering in low voices about the parcel the strange girl had given them, and what could be so special about it to earn a hundred thousand galleons. After a while, Fred had to stop George from opening it in front of everyone. ("You'll ruin everything!")

Once they did get home, however, it was a different story. Nobody was in - Ron was off with Harry and Ginny somewhere, and their parents had gone off to visit some muggle place for the day. Giving no thought to Percy, who would obviously be in his room, studying, they ran into their room and shut the door.
"Okay, so open it!" George chirped, once they were both sitting on the bed belonging to either Ron or George - neither cared which. Fred grinned and ripped off some of the brown paper. There was a box, and a piece of parchment. Reading a bit of the writing, Fred frowned. George began to get impatient. "How 'bout reading it out loud?" he asked. Fred looked up.
"Kay... Says here we have to drink the stuff in the bottles, one each, and then wait five minutes... Says we'll know what to do then..." Fred frowned once more. As though reading his twin's thoughts, George spoke up.
"But how exactly are we meant to know?"
"I don't know!" Fred shook his head and opened the box, not noticing the smaller box in there. He picked up the two relatively large bottles and opened one, handing the other to his brother. George stared curiously as Fred drank almost all of his in one go. "Tastes like butterbeer..." That set George off. He swiftly opened his and drank just as much as Fred had, while Fred was drinking the rest of his.
"Yea, it does. Wonder what this is supposed to do to us..." Instead of waiting for a reply, George downed the rest of his and got up. "Come on, Fred! If we have to wait five minutes, let's at least bug Percy!" Fred grinned, got up, and they went off.
