Demon Lover.

Chapter One.

'Bloody meat bags' thinks Dean as he walks along the street heading for his favourite bar. He looks up and see's the most amazing blue eyes he's ever seen then the guy looks away, the demon follows him with out thought…curious wanting to know more about the man. He was definitely human, Dean was sure of that much at least. But where does a human get eyes like that? So blue…so sad, yes that was it sad. He knew that emotion or recognised it at least because he had been the cause of it more than once. The man walked three blocks before stopping to pull out his phone which was vibrating. He pushed a button and read the message. He sighed and put his phone away without even replying. The man walks on. The demon follows. An hour later and the man walks up to a house and pulls keys out of his other pocket. Gets to the door and unlocks it, pushes it open and steps inside, closing the door behind him. The demon grins and thinks 'So this is where he lives…I'll have to visit some time'.

The man tosses his keys in the bowl on the kitchen counter and shrugs out of his tan trench coat, draping it over the stool. He sighed and thought 'So sick of being alone'.

The man goes about his usual routine of feeding himself then watching some TV before a shower and bed. Trying not to think about how much his life sucked. How boring and lonely it was, how unfulfilling his job was. It's one of those nights were there is nothing good on TV so he goes to bed early. Thirty minutes after his head hit the pillow he was asleep. An hour later he was dreaming of lips on his neck, a hand on his inner thigh. He moaned and shifted in his sleep. Kisses on his bare chest and he gasps, he likes this dream. Wants to see who is touching him so perfectly. But he can't sit up and soon it doesn't matter cause those lips are on his stomach and moving lower every second. He moans again and gasps yes. Lips kiss his hard on and a tongue darts out to lap at him. Oh he likes this vivid dream. The glides over every inch of him before he is enveloped in a warm wet mouth, he moan low but still can't move. The dream lover is sucking him hard, stroking with their tongue as they do. This feels so good. He's never had better, in dream or reality. He's drowning in sensation, moaning yes as he gets closer to cumming. As if knowing this the dream lover sucks harder, faster…puts more pressure into the tongue.

"Oh fuck" he cries out in his sleep as he spills his seed down the willing throat of his dream lover who swallows it all and slowly licks him clean. He moans in his sleep and can move again, his hands search but find nothing and he remembers he's dreaming. He drifts deeper into sleep a sated smile on his face.

The demon stands at the end of the man's bed, licking his lips and thinking 'Hmm, tasty'.

Another day…more souls to corrupt and he was good at his job. There was nothing Dean wouldn't do to help damn a soul to hell, to say he loved his work was an understatement. He was very inventive too which stoped him from getting bored easily. Dean had the highest soul count in hell and wasn't giving it up any time soon. He started off the day by encouraging a catholic priest to bugger an altar boy then moved on to get two fifteen year old girls strung out on crack.

'Good start to the day' he thought as he sat on a bench thinking of what to do next.

'I could go down to the subway and nudge some poor sap to push another meat bag in front of a train, I could encourage a whore to kill her john, I could go see what he's doing…shit, what? Business comes first, now where was I…oh yes I could go play in that convent awhile' the demon thought.

Dean ran through a list of things he could to send souls to hell but none of them struck him as fun and he frowned. He always had fun on the job…he got creative then.

'I'll nudge a bus driver to crash a bus load of meat bags into a lake or oncoming traffic, I could…um, crash a plane…that's always fun' he thought.

'Have to check he's not on any of them though' he thought then cursed himself for being so damned soft. He was just a meat bag after all, a very hot, very tasty meat bag. The demon groaned at himself in disgust and thought 'Fuck it' then vanished.

He reappeared close to where he sensed the man to be and scanned the area for other demons. Finding none he walked over to the building and vanished to appear inside. The demon looked around and saw that he was in an office…an answering service to be exact. He was invisible and wandered around to find him, it didn't take long and the demon was practically standing next to him. A grin on it's face as it watched the human talk while making notes. Dean stayed an hour then went back to his own job…grinning because he now knew the man's name…Castiel.

When Castiel gets home he's in a bad mood, last night's dream had him distracted most of the day. He had tried to stop thinking about it but couldn't, the worst was not knowing who had been the dream lover. He went about his usual routine listlessly and soon found himself sitting staring at the TV but not seeing it. He was thinking about the lips that had so expertly sucked his cock last night, he groaned and berated himself for his lack of focus and will.

'It was just a fucking dream' he thought and tried to focus on the show again. No such luck so he switched off the TV and went to have a shower. As the hot water ran over his skin he sighed and stretched himself. He swears he feels breath on his ear but no one is there when he looks so he puts it down to an eddy of cool air and relaxes again. He leans on the tiled wall, enjoying the warmth and his hand moves to the hardness between his legs. He strokes himself slowly, thinking about last night's dream. He pleasures himself but it's not as good as his dream and he stops, shakes his head and lets go of himself. He finishes his shower, dries himself off and goes to bed. Sleep takes him shortly after. He dreams…not the dream he had hoped for. He dreams of eyes…green eyes with just a hint of gold. Staring at him intensely. Such green couldn't possibly be human. The eyes are beautiful and he drowns in them. He stirs in his sleep as the demon looks down at him intently and licks it's lips remembering his taste. Dean grins as an idea takes shape in his mind…his most creative one by far. This one would beg for hell when he was done with him.
