According to Ausiello over at EW.com, there will be some shirtlessness happening soon on Supernatural:
One of the of the Winchester brothers will partake in a shirtless (and presumably pantsless) sex scene before the end of November sweeps. Even more shocking than that? The deed is done at a location Supe fans hold sacred.
Now, if I were to venture to guess, I'd say it'll be Dean in the Impala. Or is that just my wish?
