The air in the bunker’s hallway thickened, saturated with a scent that cut through reason—sweet pine and dark toffee, musky and utterly intoxicating. It bypassed Sam Winchester’s thoughts and went straight to the wild, dormant part of him he’d never known. His brother Dean, an alpha himself, had warned him away from Castiel, but this was different. It called, a primal pull he couldn’t ignore. Sam pushed open the door at the hall’s end, his heart pounding against his ribs. Inside, the omega lay curled in a makeshift nest of blankets, unaware of the alpha now standing in the doorway. A strange, unfamiliar heat pooled low in Sam’s belly, confusing and insistent. He swallowed hard, his hands tightening into fists, fighting the savage urge to claim what that scent promised.
