Dean slammed the door of his room closed, stormed over to the bed, and threw himself down on top of the blankets. He was so pissed right now he didn't know what to do. Dean knew about Sam and Gabriel, he knew the very first time they had hooked up, but adding Lucifer to the mix? That was just to much for him.

"Damn it Sam."

Dean rubbed his eyes wishing he could remove the mental image of those three all lying naked on the bed together. He really didn't need to see his brother's naughty bits first thing in the morning.

"Dean?"

Dean sat up and looked to his left. Castiel was sitting in one of the big recliners a foot from the bed, concern clearly written on his face.

"Are you okay?'

Dean sighed heavily.

"Honestly no I'm not okay."

Dean gets up and heads over to the fridge. Pulling out a beer he pops the top off and downs half the bottle in one go. Walking back over he stands in front of the the bed facing Cas.

"I mean Sam and Gabriel sure. I mean I don't get it, but whatever that crazy trickster is his problem."

Dean drained the rest of his beer finally feeling some of the desired effects.

"But the Devil?! Come on man that's just plain stupid even for Sam."

Dean walks back over to the fridge getting another beer. This time he drains the whole thing and grabs another before walking back over to the bed.

"I mean seriously! Does he not remember what that dude put us through! He tortured Sam in the cage, beat the living shit outta me, I mean hell, he exploded you Cas!"

Cas looked down at his hands awkwardly. He understood why Dean was angry. He didn't feel the same way but at the very least he understood. Cas had never met Lucifer, but from the stories he heard in heaven Lucifer had always been a bit of a wild card. He did what he wanted when he wanted. He spoke his mind, never telling a lie, even if it meant him getting in trouble. From the looks of it, hell did very little to change that.

"I just don't get that kid sometimes. He even admitted that he didn't want the dude there in the first place and now all the sudden everything's all fine and dandy!"

Dean took a long swing of his beer. He could tell the alcohol was starting to have a serious effect on him but he didn't care. Honestly he just wanted to get drunk and forget he ever walked into that room in the first place.

"I mean come on! Of all the people they could've invited in they pick the biggest dick we know!"

Dean lifted his beer up to his lips taking another long drink. Cas looked up from his hands and saw something he didn't expect. Lucifer was standing a couple of inches behind Dean. Cas began opening his mouth to ask him what he was doing but stopped when Lucifer motioned for him to be quiet. Cas looked at him confused. What was he up to?

"Come to think of it, is that the reason, cause I just don't get it. The only reason I can think of for Sam to just say 'Sure why not let the devil screw me!', is that he's the biggest dick with the biggest dick! Im tellin ya the dude must be packin cause, I don't get it!"

Dean paused finishing off the rest of his beer. Lucifer took the moment to lean in, stopping not even an inch from Dean's ear.

"Wanna find out?"

Dean choked spewing the beer out of his mouth. Quickly he spun around to confront the voice behind him but found no one there.

"Jumpy isn't he?"

Dean spun around again this time finding his target. He couldn't believe what he was seeing. There sitting in Cas's lap, arm slung over the back of the chair, was Lucifer himself. The archangel smiled at the older hunter.

"What the hell is wrong with you?!"

Lucifer laughed softly.

"Oh come on Dean, I'm just having a bit of fun."

Lucifer turns looking at Castiel.

"Can't take a joke this one can he?"

"Get the hell away from him you son of a b-"

Lucifer snaps his fingers sending the hunter flying back onto the bed. Dean tries to get up but can't move.

"You gotta be freakin kidding me."

"Dean, Dean, Dean, you got me all wrong."

Lucifer takes Castiel's face in his hand, squeezing his cheeks together.

"Look at this adorable face. I could just eat him up."

Lucifer lets go of Castiel, stands, then walks over to the end of the bed. Dean tries to move but is still stuck.

"What the hell do you want?"

Lucifer folds his arms across his chest and smiles.

"Well Sammy feels a little guilty about upsetting you. Why I don't know, but like the kind hearted devil I am, I told him I'd come talk to you about it and here I am."

Lucifer walked around the right side of the bed sitting down beside Dean's hip.

"So, Dean, talk to me. What's really bothering you hmm?"

Dean scowled clenching his jaw.

"Hey hey don't be like that. Come on this is a safe space. Are you angry, hurt, confused?"

Dean refused to talk. No way in hell was he letting this phyco get a rise out of him.

"Oh I get it! Maybe you're a little jealous hmm? Look it's okay, I mean I get it, you're just feeling a little left out. Here let's kiss and make up okay?"

Lucifer scoots forward and leans in puckering his lips.

"GET THE HELL AWAY FROM ME!"

Dean struggles violently trying to break the invisible bonds holding him. Lucifer leans back laughing.

"God you're so much fun to teese."

Castiel sighs, stands up, and walks over to the bed.

"Lucifer what is it you want?"

Lucifer looks over at Castiel smirking.

"Not much. World peace, daddy's love, and for Dean Winchester to come down off his high horse."

Castiel cocked his head in confusion.

"I'm afraid I don't understand."

"It's simple. Dean here is upset because of yours truly making it with his little baby bro. He thinks we did something to trick Sam into having a good time. Well, the way I see it, if he has good time with you and I then there's no need for him to be upset."

Cas paused thinking on this a moment.

"Cas, dude, you can't seriously be considering this man? He's evil!"

"Actually I'm not. Sadistic, sarcastic, and short tempered, but evil is not one of my traits. I am an angel after all. One of god's children and all that. Just because I don't like you humans running the show, your lot brands me as evil. I mean have you seen some of the things you hairless apes have done throughout history. Now that's evil."

Castiel turned towards Dean.

"He has a point."

Dean stared back at Cas mouth hanging open in shock.

"Are you freaking kidding me Cas?!"

"Lucifer is many things but evil is not one. Even Gabriel has admitted that fact."

Lucifer smiled clapping his hands together.

"Now that we've gotten that all cleared up, let's get this party started shall we."

Lucifer turns smiling wickedly at the defenseless hunter. Dean gulps loudly his pulse hammering in his ears as Lucifer reaches his left hand out towards the hunter's waist. Cas places a hand on Lucifer's right shoulder.

"Wait."

Lucifer sighs withdrawing his hand.

"Come on Castiel. You said yourself that Dean fought you at first."

Cas looked from Dean to Lucifer unsure of what to do.

"Okay here how about this, let's make a deal. I get ten minutes to convince scaredy cat over here how much fun I can really be. If he's still not into it after the ten minutes I'll stop and Gabriel can send me back to the cage."

Castiel thought about it for a moment. It was a good deal. If Lucifer won Dean couldn't be mad at Sam or Gabriel and if Dean won Lucifer would be sent back before he could do any damage to the world.

"Okay."
