The pulse on her neck.
So close.
He could almost smell the blood through her skin.
He needed it.
The world narrowed to that pulse point. Nothing else mattered.
He nicked her and was lost. Lunging at her neck, he urgently lapped at the warm blood.
He was electrified as the effects took hold – power surging through his body.
Finally, sated, face smeared in blood, Sam turned and looked at Dean. Saw the silent appal – the wounded disbelief.
Tomorrow the splintered bond between them would haunt him.
But right now – with his veins on fire - it just didn't matter.
A/N This is not an anti-Sam story. I love Sam and I am absolutely sure he is going to be just fine - eventually.
