Author's note: My first attempt to write in English. Trying my best, but would love to hear from you about mistakes or just notes and wishes.
"Guys! You will never believe what happened during the summer!" Sirius got into Hogwarts Express compartment. Remus were already inside eating some snacks.
"James is the headboy, right? He wrote me few days ago" Remus smirked, leaving Sirius to his disappointment as he was not the one to break the news.
"Yeah, heard it from Remus already. Dumbledore might be crazy" Peter fidgeted on his seat.
"But, guys! You know what that means? No one will stop our pranks this year!" Sirius put his bag on the shelf and looked at his friends with excitement.
"Except for Lily" Remus noted.
"Except for Lily. But, she will be distracted" he smirked.
"By whom?"
"James, of course! Come on, guys! There's totally some sexual tension between these all this time together" Sirius had no time to finish his thought as the door opened and Mary McDonald walked in.
"Hey, guys! Have you seen Lily?"
"Oh, hi Mary! I think she's busy with all the head girl's duties" Remus replied and took out fresh Daily Prophet from his bag.
"Oh, right! I already forgot. Can you believe that they chose James as head boy? Bloody hell, what were they thinking? Anyway, I'll be in the next compartment with Frank and Alice. I mean, in case you'll see Lily" She said it as fast as she disappeared. Right after her in the corridor appeared Marlene and as she passed by, waved her hand and showed a big fat yellow square bag. Sirius almost jumped on his seat and was filled with excitement. Everyone knew what this bag meant.
"I guess we will have a groovy party!" I light flickered in Sirius eyes, meaning trouble was on it's way.
"Did somebody say party?" - James appeared in the doorway as the train started moving. He was already wearing his cloak with a special head boy badge.
"Hey, James! How's your head boy duties?" Remus asked and turned newspaper page..
"Merlin's beard! It's so exhausting! And Lily is always there to boss me around" James sighed. "So, what about the party? Are we going to throw Welcoming party this year?"
"Marlene brought a huge pile of vinyl. And I guess it means only one thing! Boogie all night! " he rejoiced and made a howling sound only to see Remus' drilling look. "What? It was dog howl! We are a pack of cool dogs!"
Everybody laughed and Sirius just shrugged and offended, looked out of the window.
"Oh, little Sirius doesn't like when people make fun of him!" - Peter giggled.
"Come on! Ok, in exchange we can let you tell us how many girls you banged this summer." - They knew that Sirius couldn't wait to boast about his new adventures, as he did every year in Hogwarts Express. But since James and Sirius started living together, Potter was so tired of his friend's neverending sex stories that let him spill it all out only on special occasions.
Sirius' face lightened up with joy as he exclaimed "Ok, there were four! First one…"
"FOUR? Man, you're might be losing your charm" Remus interrupted and laughed.
"Wait till you hear it! None of the last year girls compare to this year ones!"
Friends relaxed and started listening to everyones summer stories.
"James Potter are you serious?" Lily appeared in the doorway, her face was red with fury.
"No, I'm Sirius! And hi to you too!" Sirius smirked.
"Very funny, Black!" she snapped "James you're a Head Boy! We're almost arrived! You and I are supposed to help Prefects watch over the first years!"
"And I thought that it's gonna be fun!"
The train stopped and the Marauders started their last year at school.
