Jack braces himself, but he can't help but cry out as Castiel's hand sinks into his stomach, touching not exactly his insides but his very core. He doesn't move - he doesn't know what will happen wrong if he does and Castiel did tell him to stay still - save to turn his eyes upwards. He probably should have asked how long this is going to take, he thinks to himself, and it's all that he can do to keep from screaming.
