First True Love

Author's Note: I LOVE Sirius Black! He is one of my favorite HP characters next to Ron and I was kinda upset at what happened to him in the fifth book, so with my extremely overactive imagination, I'm doing this fic for him!

Disclaimer: I don't own HP or the characters, but I do own the female that Sirius will fall for! :D

Chapter 1

James Potter yawned as he and his best friends Sirius Black and Remus Lupin sat at Kings Cross with their friend, Arthur Weasley. The three nineteen year olds, a twenty three year old red head, had been at the station since eight that morning. They had all been friends since their first year at Hogwarts, so that all had pretty decrent friendships, though James, Sirius, and Remus were inseperable. Through the years, they all became close in different ways and had seen some very interesting events together- but this event was only because of Sirius and his crush on Arthur's little sister, Cassie. Sirius had a thing for Cassie Weasley since she came to Hogwarts, her first year, his second. She didn't really pay him any attention though, Sirius being very popular with the girls and to her, an extrememly immature troublemaker.

Sirius, of course, wouldn't accept this and continued chasing after the young red head up until today. The day the young Weasley girl would be free to do what ever she wanted, including moving out of her parents house. Sirius grinned to himself. That was when he would come in. He's invite her to live with him and the plan would flow from there. "What are you so happy about, Sirius?" came James's voice. Sirius looked over his shoulder at his three friends.

"What? A guy can't smile without a reason?" He asked brightly. James rolled his eyes and Remus chuckled. He was sitting between James and Arthur, his arms crossed and eyes closed.

"Haven't you put the signs together yet, James? Todays the last day of school. Lovely Miss Cassandra Weasley ends her seventh year old Hogwarts today. Arthur has come to pick her up..." Remus opened his eyes and looked at Sirius with a smirk. "And he's waiting for his chance to ask her out again."Sirius looked at Remus and blushed.

"I am not!" he announced, probably too defensively. James laughed.

"Padfoot, is it possible you're whipped?" he asked. Sirius glared at James.

"I AM NOT WHIPPED!" he said with a growl. "And you're one to talk, Prongs. 'James! Don't do that', 'James come with me.', 'James if you cared...'" Sirius mimicked in a high pitched feminine voice. James blushed deeply and Remus laughed along with Arthur. Arthur pushed his glasses up his nose and shook his head.

"You two are insane." he laughed. The two best friends stopped glaring at each other and looked at Artthur and Remus.

"He started it!" they said in unison. Remus rolled his eyes.

"Grow up you two. I doubt Lily or Ickle Cassie would find the way you're acting to be attractive." Both James and Sirius looked at their friend with a raised eyebrow. They knew he was right, but they usually refused to admit it. They remained silent for the rest of the wait until students and parents began flooding the station.

"Wicked, they're here!" cheered Sirius and ran straight towards platforms nine and ten. He had vanished before any of his friends could say anything. Remus chuckled and shook his head.

"Ah, to be young and in love."

Sirius was craning his neck, trying to see through the mass of students. "Where is she?" he thought outloud. Students were everywhere and he was becoming truly annoyed. He growled and got ready to pull out his wand when he saw a flash of red hair. His eyes instantly lit up. "CASSIE!" he called and shoved everyone in his way down. The red head he was running towards didn't get a chance to react before he grabbed her up in his arms and hugged her tightly, lifting her from the ground.

"SIRIUS!" she announced. He put her down and grinned handsomely.

"Yes love?" He asked, his eyes shinning. Cassie laughed and pushed some hair out of her face. She was truly a beautiful girl, as well as sweet and smart. Sirius couldn't help but fall for her.

"Never mind. Where's my brother at?" Sirius blinked and looked around. He just remembered he left the others behind.

"Uh... left him with Prongs and Moony." he answered innocently. Cassie rolled her eyes and smiled at Sirius.

"Of course you did." she said. Sirius smiled.

"Did you miss me?" he asked as Cassie began walking off, the nineteen year old boy at her heels like a puppy with his master. "I know you had to." Cassie rolled her eyes and glanced at Sirius as she pushed her trolley to the barrier.

"Yes Sirius, I missed you." she said, smiling at him sweetly before going through the barrier and ending up on the other side, facing Arthur, James and Remus. She grinned and hugged them all happily. James grinned at the look on Sirius's face. He seemed so put out at the moment. Sirius noticed the grin on his friend's face and scowled. James smirked and leaned down, whispering something to Cassie, who blinked and looked at Sirius. She smiled at him gently and Sirius blushed. Arthur smiled brightly at his little sister.

"Well Cass, you've officially graduated Hogwarts, what are you gonna do now?" he asked. Cassie laughed and beamed at her older brother.

"Well I was thinking about settling down like you and Molly and having kids." Arthur scowled. "But I think I'll wait a while before I do that. Oh, and I plan on moving out of mum and dad's place."

"YES!" The group all looked at Sirius who blinked and grinned sheepishly, rubbing the back of his neck. James rolled his eyes.

"You know Cassie, Sirius has his own place. You should move in with him.... It needs a feminine touch." he informed.

"WHAT'S THAT SUPPOSE TO MEAN?!" announced Sirius and shot a glare at Remus, who was snickering. He cleared his throat and looked at Sirius innocently.

"C'mon now Sirius. Your place isn't the best... or cleanest..." Sirius growled and seemed ready to pounce on his friends. Cassie smiled at them.

"You know, that may just be a good idea. What do you think Sirius? I need a place to go and I trust you more than some of my female friends." He stared at her in shock and a slight blush crossed his face.

"Really?" Cassie laughed and nodded, causing Sirius to grin widely and nod. James could tell his friend was truly happy, and for some reason felt Cassie would have wanted to live with Sirius even if they hadn't brought it up.
