Dean was slowly drifting off to sleep. He was lying on Castiel's chest, listening to the fallen angel's heartbeat. It was the most comfortable he could ever remember being.
"Dean," Castiel said, "I cannot sleep."
Dean sighed in frustration, lifted his head, and looked at Castiel.
"Close your eyes and count sheep," he said, and then he put his back down, snuggling closer.
"I do not understand how counting livestock is supposed to help me sleep."
Dean sighed again. He lifted his head from Castiel's chest and shifted to lie on the pillow next to Castiel.
"Counting sheep is supposed to make you so bored you fall asleep," he said. "Just close your eyes and try it."
"Very well then." Castiel closed his eyes and Dean watched the rise and fall of his chest. After less then 30 seconds Castiel opened his eyes. "It's not working."
"Well, then count something else." Dean said. He really just wanted to sleep.
Castiel turned so he was facing Dean. He was silently staring at him.
"Cas, why are you staring at me like that?"
"I am counting your freckles," he stated simply.
"Why?" Dean started blushing.
"You told me to count something else."
Dean kissed Castiel chastely, and closed his eyes. He could feel Castiel continuing to stare at him. He curled himself around Castiel's body.
After two minutes, Castiel's breathing evened out.
Dean fell asleep shortly after.
