Dean was in the middle of his guilty pleasure, reading Cosmopolitan, and was halfway through the quiz when he reached a question that read "How good are you in bed?" He couldn't stop himself from muttering, "What the fuck?"
"So how good are you, Dean?" came a voice from over Dean's shoulder, causing him to jump, accidently sending the magazine across the room. Cas looks at Dean, confused, as per usual, and says, "What's wrong, Dean? Just answer the question."
"What?! NO!"
"Why? Is there something wrong with the question? Just answer it, Dean."
"No, Cas!" Dean sputters, ears turning red.
"Just answer the question, Dean..."
I'll let your imaginations run with that... haha... but for me, Cas finds out how good Dean is.
Gabriel looked at his younger brother, smirking, "So did Deana find the magazine?"
"What magazine?" Castiel asked, raising an eyebrow.
Gabriel raised an eyebrow in return and his smirk grew more mischevious.
Castiel turned red, as he realized which magazine... and he gave a small smile and a quiet, "yes."
"What was that, lil bro?"
"Shut up."
