Dean's never seen Cas without a shirt on. Which is odd, but Castiel was an angel, so maybe it was normal.

But that changed completely today.

After a rough hunt that got everyone caked up in mud, they all left to take showers. After Sam showered he left to go some more soap, leaving Dean and Castiel alone.

Dean had already tooken his bath and was watching TV when Castiel walked out, completely shirtless, and damn.

Dean felt like a damn teenage boy again, while he oggled at Cas.

Damn.
