See, this is the bad thing about Cas. He used to be the cautious type, even meek (by angelic standards anyway) but ever since he'd decided to rebel against Heaven it's like he adopted some of Dean's worst traits. Occasionally being impulsive. Usually when making horrible life choices, like drinking a liquor store or frenching a demon. These are not good life choices but at the time they'd seemed really damn bright.

Like now. Cas shudders, exhales shakily and grips the back of Dean's hair, rubbing against his leg like some kind of dog in heat. He doesn't even care how undignified it is because it feels really, really, really good.
