Okay well this is simply to fix my Demon!Castiel kink I have. It's just a little one-shot but it might turn into a verse fic if I get more idea's for Demon!Castiel. I hope you all like this and if you have idea's for this possible verse then let me know!

I don't own Supernatural or the show would be a little gayer!

Things were never supposed to happen like this, no matter how Dean pictured his life it was never like this. He'd imagined life, if he settled down, with a woman and maybe a dog or something. Hell maybe a kid in the future if he quit hunting. Their house would be out in the country, where he could have his own space like he'd always wanted. He pictured a job as a mechanic in town where he was his own boss, just how, when he was actually thought about it, he pictured his life.

Where he was now, was never anything he pictured for himself. Dean was laying in the middle of the bed in the old motel room listening to Castiel in shower from the bathroom. He and Sam had taken to getting different rooms whenever Castiel was with them. Glancing around the room he let his mind wonder to Castiel, the one who saved him from hell, the one who loved him, the one he loved, Castiel the demon.

When he'd been pulled from hell he had a feeling it was a demon, he hoped he was wrong and that something else had saved him, but he always knew. So when he met Castiel in the barn he had a flicker of hope, that the man was something different. However when his eyes turned black, that hope was crushed.

Luckily Castiel wasn't like most of the demons they met; he'd for some reason grown attached to the human while he was in hell. He'd been shy, he remembered him once when Castiel told him that it had been him. Castiel had given him water, in hell he was given water and the one who did it was Castiel. That was what made him last for the ten years before he said yes. Maybe the knowledge of that made him let the demon in. Castiel had reveled Ruby for the bitch he was and saved Sam. He was almost good, but he was still a demon and the sadistic side ran deep and sometimes it really showed.

The sound of the bathroom door opening brought his attention back to the room. A small smile come to his lips as he saw Castiel leaning against doorway dressed only in his boxers drying his hair with a motel towel. A laugh escaped Dean's lips as Castiel tossed the towel aside showing off his overly messy hair. Castiel raised an eyebrow at him as he heard the laugh.

Shrugging his shoulders Dean grinned, "You look cute Cas." Before he knew it he had an armful of the demon.

Looking up at Castiel he clenched his jaw at the smirk on the other man's face. "Cute?" his eyes flashed black with the word. "I'm a demon Dean, not cute." He let out a slight yelp as Castiel bit down on his neck drawing the slightest bit of blood.

A slight moan managed to get past his lips as Cas ran his tongue over the already bruising mark on his neck. Wrapping his arms around Castiel's neck he let out a breath trying to push him away lightly. He didn't want to start anything tonight, Castiel was in one of his rougher moods and that wasn't what he wanted now. He wouldn't be forced into anything but he wouldn't enjoy what would happen if Cas really wanted this.

"Can we not…" Dean started when Castiel's lips captured his in a small kiss. "Thank you." He muttered when the demon moved off of him laying by his side. Quickly Dean threw his arm around Castiel's chest placing a kiss on his shoulder.

They laid in bed for a moment before Castiel grabbed Dean's jaw once again letting his eyes go black. "I think you should rest tonight. Tomorrow I do expect to have you Dean Winchester."
