Prompt: Cas wants to learn about the certain...benefits of humanity.
"Hello, Dean."
He was sitting on his bed doing a crossword puzzle when Cas poofed in naked. Well, he wasn't so much filling in the crossword as staring at all the clues he didn't know.
Wait. Cas was naked?
"Cas! What the hell?" Dean threw his book, well, Sam's book, to the ground sat up.
"I want to experience the physical pleasure that humans enjoy so much."
Dean nearly choked. Then, he laughed. "Hah. Good one. Now get dressed. Ok?"
"Dean," Cas said almost solemnly. "I am being serious."
A million thoughts raced through Dean's mind. There were so many ways he could take this. The only problem was which one to choose?
"Um…Alright, Cas. Gimme time to shower and we'll go out to a 'palace of fornication" as you call it and—"
"Dean."
This time when Cas said his name, he could almost feel the word wash over him, sending tinglines down his spine. Which sounded like crap. He'd apparently been listening to Sam too much.
"Cas," Dean murmured with the same reverence. "Why me?"
"You're the only one I trust."
Sam walked into Bobby's house. Damn, but it was cold outside. Rubbing his hands together to warm them, he called out, "Dean?"
The racket that came from upstairs scared Sam so much he bounded up the stairs three at a time.
When he opened the bedroom door, the sight that met his eyes nearly caused him to faint. And Sam doesn't faint.
Dean was on the ground with a pillow covering his soft spots, which Sam figured were not so soft at the moment. Cas was on his knees on the bed, nothing covering him.
"Uh…" Sam managed to get out before he flat out grinned. "You guys okay?"
Cas truly smiled for the first time Sam could remember.
"Yes, Sam. We are well."
Dean was red with embarrassment all the way to his ears.
Sam sloced the door and laughed. He couldn't wait to tell Gabriel.
