Sam’s breath caught in his throat, and he hurried to close the laptop. So much for being home alone! Had…had Castiel seen anything? “Uh, hey, Cas!” His voice sounded strange, and his heart was pounding all out of rhythm.
“Are you all right, Sam? Your pulse is quite fast. Did I startle you? Has something upset you?” The clear blue eyes were giving no indication they had seen anything.
He shook his head. “You’re, um…you’re right. I should…go to bed.” Sam grabbed his phone and smiled weakly at the angel. “Thanks for coming to-to check on me or whatever,” he fumbled as he rushed from the room.
Castiel smiled behind him. He waited until the door to Sam’s bedroom closed, then silently opened the laptop. He sat down to read Sam’s latest chapter, feeling the warmth filling his stomach.
“He liked to think of him as his angel. Sam knew better. But in the privacy of his own head, he liked to pretend this beautiful creature was his.”
Soon, when he thought Sam wouldn’t be mortified, he would speak to him about this. But until then, he thrilled with every update to the work in progress. Sastiel was Sam’s angel’s favorite, after all.
