Dean like this is an invitation to sin, his broad freckled shoulders and his neat narrow waist, the smooth line of his clavicle jutting above the rise of his pectorals, casting shadows. Castiel wants, when he lets himself look, to touch him, but Castiel has no hands of his own, no body with which to cover Dean's.

Frustrated!Cas is seriously entertaining...I love the idea of Cas possessing Sam considering the whole 'you're an abomination' bit. He'll get more insight into Sam I hope.
