Wolf on wolf

Part 5

"Then I'm going to go do some research on wolves," Sam knitted his brows, taking the book from Castiel and walking out of the room to find his laptop.
"What?" Dean asked breathlessly, he had been too distracted looking at the angel to pay attention to the conversation.
"He's going to do research on wolves," Castiel clarified.
Stalking over to the back of the sofa, Dean was turned to look at him, heartracing. "Why?"
Dean almost whimpered when he got a fresh wave of Castiel's scent, it was overpowering, making every nerve in his body tingle. "Because that's what she's cursed us to be like. Are you sure you'refine?" Castiel furrowed his brow, closing into Dean's personal space to give him a once over. Dean couldn't control it, and he turned beet red when awhimper escaped his lips. "Dean..."
"So get this," Sam came back into the room with his laptop,"apparently the most prominent thing about wolves is their hierarchical structure of alphas, betas and omegas. Besides the good hearing and Smell this is what stands out most about them. Alphas are the leaders, with betas being next while omegas are at the bottom. The alphas get to mate with whomever they want and when they're in heat can breed with any other member of the pack, usually an omega who they can put into heat."
"How powerful do you think the witch's magic is?" Castiel asked.
"Why?" Sam was confused by his question.
"Do you think she could have affected the entire planet with her curse?"
"What?"
"I think her magic has affected me, this vessel I mean."
"Really? I think she could, I remember her talking about how she hated humanity and was going to change it for the better. Maybe she thought that if everyone acted like wolves who she obviously admired, it would solve a lot of problems."
Dean squirmed on the sofa, feeling hotter by the second.What was wrong with him? He remembered Sam's words, that wolves went into heat...did that make him an alpha? He turned to Castiel who was staring back at Dean, the scent spilling from him making every fiber inside him want to submit to the angel. The gears in his head finally clicked in Dean's head as he realized with slight horror that he was an omega...and Castiel was the alpha who wanted to breed him.
