This is dedicated to my friend Fran, stay crazy! Dean is 20, Sam in 16, Cas is 20.

An ear splitting scream filled the the air. Dean woke with a start, jolting out of bed, getting tangled in the quilts, and toppling to the ground. He struggled into his pants as he ran down the hall towards the sound, his brother Sam scrambling out of his room close behind.

"Cas!" Dean yelled as he threw the door open to his friend's room. He froze in the doorway when he spotted a dark haired girl sitting in the centre of his friend's bed. "Who the hell are you?"

"D-Dean," she muttered helplessly. Confused understanding flickered in Dean's eyes.

"Cas?" The girl nodded miserably. "Oh my god. What the fuck did you do?"

"I-I didn't do anything." Castiel frowned.

"Then how'd-" He paused as his eyes wondered over Castiel's frame. He mentally scolded himself when his gaze lingered on her chest. She had a nice frame, cute curly hair that fell to her shoulders, and a cute baby face. "How'd this happen?" He motioned to the whole of Castiel.

"I don't know." She cried. She pulled her large tank top strap back over her shoulder.

Dean's cheeks flushed slightly. "Well until we've figured out how to fix this..." He turned around. "Find something that actually fits you."

He left the room, followed closely by Sam. A mischievous glint filled the long haired boy's green eyes. "Dean and Cassy sitting in a tree-"

"Shut up Sam." Dean growled.

Sam sniggered. "Don't act like you weren't looking, I caught your eyes."

Dean said nothing as he walked into the kitchen to cook some burgers. Minutes later Castiel wandered into the kitchen in a large plaid shirt. Her hair was messy and she looked uncomfortable, for which Dean didn't blame her.

"Burgers will be done in ten." He muttered, trying not to stare at her too long.

Castiel nodded. "That'll be good." She stayed standing by the table, tugging at the ends of her shirt.

"Well?" Dean motioned with his spatula to a chair. "Have a seat, why don't you?"

"I-I'm not..." She blushed darkly and looked at her feet. "I'm not wearing any underwear... None of them fit me."

"Oh god." Dean bit his lip. "Fine, fine. We'll go shopping later." Castiel nodded her thanks. She watched Dean closely as he placed the burgers on the table. "Well, chow down." Castiel nodded again and slowly started eating. She smeared ketchup on her chin which Dean found adorable. Sam was staring at Dean and when the older man glanced at him he smirked suggestively. Dean glared. "Shut up."

"He didn't say anything." Castiel said slowly.

Dean glared for a second longer before turning his venomous gaze to his own burger. They ate in silence for a few minutes before Sam broke it. "So, Cas, do you have any idea how this happened?"

"No." She shook her head, tugging at the bottom of her shirt again. "I stood by the window looking outside at the stars before I went to bed."

Dean nodded. "Is there anything you said or did?"

"I was staring at the stars and I said they were beautiful." She said softly.

Dean nodded slowly. 'You definitely are beautiful...' He shook his head vigourously. Sam raised an eyebrow at him. "Care to share?"

"Shut up." Dean stood quickly, picking up his plate. He grabbed Castiel's plate as well as he headed to the kitchen. Castiel made no arguments, just followed him closely. She tugged at her shirt again to make sure she was covered. "Do you have any pants you can wear? You aren't going out like that."

"No..." She frowned. "I only have my jeans and in smaller than I was."

Dean nodded slightly. "You got a belt?"

"No."

Dean sighed. "You can borrow one of mine. We should also get you some, uh..." He motioned to Castiel's chest. "Some uh... So you don't embarrass yourself."

Castiel raised an eyebrow slightly as she followed Dean. She stood warily in the doorway as Dean rummaged around for a belt. "You're uncomfortable."

"No shit. My best friend wakes up as a girl, how would you react? You'd be on edge." He scowled, throwing a tan belt and his leather jacket to Castiel.

She caught them with a small yelp. "Th-thanks." She offered a small smile before disappearing down the hall to her bedroom.

Five minutes later she returned wearing a pair of jeans that were rolled up near the ankles and Dean's jacket. "Let's go." Dean grumbled, tossing a glare over his shoulder to Sam.

First chapter, hope you enjoyed. Peace out! ~Cat.
