"Dean, what are you—" Castiel's expression was soft and inquisitive, curiosity filling his features when he saw Dean leaning against the doorframe which leaded to the corridor leading to your bedroom, the door being wide open. "Oh,"

Dean's head drops back a little to look at Cas as he hears the realisation in the angel's voice and his expression grows smug, "You found it yet, Cas?" his tone is teasing, however his eyes slowly trail back to your figure.

"Get away from me.." Dean murmurs the lyrics low under his breath, a grin spreading across his lips as he watches you dance to the song. "American woman.."

Castiel is positively confused, having never heard, or heard of, this song before. But what he knows is, he's enjoying what he's seeing, the sight of your hips swaying to the music is incredibly enticing and even he can't deny it.

"Come on, Cas, you're acting as if it's a cardinal sin to enjoy what's ours," Dean folds his arms over his chest, a low whistle escaping him as he admired you.

"Lust is a cardinal sin," Castiel mutters, leaning against Dean's shoulder reluctantly. He feels weird, like a creep, for watching you in your relaxed state, since you hadn't realised your boyfriends were there. However, Dean? Oh, he could stare for the longest time without any shame.

"Must be hell of a sinner then," Dean chuckles.

Besides, he was a sucker for Lenny Kravitz, and for you and Cas. Those three together? How was he supposed to stay away? No chance.
