Notes/Warnings: Just a little Deanley. I feel like giving Crowley some love and Deanley would be so hot.
Dean stared at the demon in front of him, his hand itching for the colt.
"We don't make deals with demons," he growled, earning a chuckle from Crowley. The King of Hell didn't look at all bothered to be alone with a hunter. He leaned against the wall, his legs crossed at the ankle.
"You say that a lot Winchester, but you seem to be all talk." Crowley smirked and pushed off the wall, moving closer to Dean. "Besides I don't want to make a deal with you. I've come to warn you." Dean started to move back, not realizing he was being herded back into a corner.
"Warn me? Why would you warn me of anything? We're enemies."
Crowley stopped moving when Dean's back hit the wall. He leaned forward placing a hand next to Dean's head.
"I'm not doing this for you Winchester, I'm doing this with my best interest at heart. Castiel will just be worse than Lucifer. He won't think twice about killing us demons, the scum that we are."
"So? What does that have to do with me?"
"You're his weakness, you and Sam. I want you to stop him."
"He hates me now."
"Castiel doesn't understand hate darling. At most you irk him." Crowley leaned forward again, his eyes boring into Dean's. "You will get him to release the souls."
"And what would he do with those souls?" Dean growled, trying very hard not to notice how close Crowley was to him. He tried not to feel the heat radiating off of the demon's body.
"What I would do is unimportant," Crowley said, waving his hand. A smirk twisted his lips and Dean's tongue darted out slowly, licking his own. "But the enemy you know is better than the one you don't."
"And if I don't help you?"
Crowley's smirk darkened and he moved so that only an inch was separating their mouths. "I have a way of getting what I want, Darling," he purred softly. A small sound, halfway between a moan and a mewl, escaped Dean's lips and Crowley smirked before pulling back. "I hope you'll think this through." Then he was gone, leaving Dean against the wall with a raging hard-on.
"Son of a bitch."
