I wrote this while I was bored in class. It's just a fluffy little cutesy wutesy ficlet.

"Dean?"

Dean opened his eyes and blinked a few times at the baby blue sky which was blinding him through the motel window.

"Dean."
"What the hell Cas? It's like five in the morning."

"It's five forty two."

Dean sat up and stared at the angel kneeling at the foot of Dean's bed. "What's wrong?"

"I can't sleep."
"You don't sleep, Cas."

Castiel blinked and grew quiet for a minute. He cast his eyes down. "B-but I was watching you sleep-"

"Oh, well that's comforting..." Dean interjected sarcastically.

Castiel ignored the comment. "You looked so peaceful, I wanted to try it out."

Dean furrowed his brow. "Uh..." he looked around the room and his eyes fell on Sam, snoring quietly in his own bed. "Well..." his eyes travelled back to Castiel. "Sleep... sleep just comes if you're tired."

"I'm not tired."

"Well, damn, Cas! What do you want me to do, tell you a story?"

"Will you?"

Dean looked at Castiel in disbelief. "Seriously?"

"Yes."

"Um... alright..." Dean reluctantly agreed. He fluffed the pillow beside his own and patted the side of the bed. "Come here." Castiel crawled over to Dean and hunkered down under the covers, still wearing his trench coat. Dean decided against telling Cas that it wasn't customary to sleep wearing your day clothes, but then again... Cas never changed his outfit, anyway.

"Begin the story, Dean."

"Okay... let's see..." Dean's eyes crossed back to Sam. "Sam was such a little runt in school. He's a damn moose now, but back then?" Dean laughed slightly and shook his head. "He always needed someone to look after him.

"When Sam was thirteen... there was this kid. His name was... Luke or something. Fuckin' hated that kid. He would torture poor Sammy. Sammy'd come to me in tears, 'Dean, Dean! It was Luke again...' I wanted to beat the shit out of this Luke.

So one day, I went to pick Sammy up from school and I saw this dick going at him. So I went up to him. I realized that he was a good two heads taller than me and probably about three hundred pounds. Didn't expect that from someone no older than fourteen. But I still tapped him on the shoulder and told him to leave my brother alone and to fuck off. Kid just swung, punched me right in the jaw. Asked me if I wanted to repeat what I'd said. And I did... I said, 'Leave my brother alone. And go ahead, hit me again. Just leave Sam alone...' And he hit me again, and I took that as my cue to fight the asshole. I got kinda bloodied, but Sam got back to the motel safely."

"Who won?" Cas asked quietly.

Dean laughed a bit. "Me, obviously. But I was bloodied. Didn't care though. It was worth it for Sammy."

"You really care about him..." Cas said sleepily.

"Yeah..." Dean turned towards Sam again and smiled. "He's my baby brother..."

Cas snuggled up to Dean and yawned. "I like that about you." He rested his head in the crook between Dean's chest and arm. Dean looked down and sighed as the angel fell asleep. He wrapped his arm around Cas and listened to his steady breathing. "Thanks, Cas." he whispered as he watched the sun fill up the morning sky.
