Chapter 2: Oh Hell No!

No One's Pov

"You son of a bitch!"

Dean threw a punch that hit Lucifer square in the jaw and he went down. Dean shook off the slight pain in his hand as Lucifer rallied, glaring at him with burning rage and pure distaste. But Lucifer just joked it off as he usually does.

"Nice job! But I think next time you could hit me a little harder because seriously I thought you wanted to knock me out!"

"I do" Dean moved to punch him again but Cas yet again held him back and pushed him away to talk.

"Dean this is the Lord of Hell, he is not to be messed with"

"I don't care! He's not having you Cas!"

"I believe that's up to Castiel" Lucifer spoke from behind Dean. He swung around to get another hit in but he vanished and popped up behind Cas. Then leaned forward to whisper in his ear.

"What do you say Castiel? Care to spend a night with the Devil? I'd love to make a sinner out of an angel"

"That's flattering but I must decline. I'm not for sale as some would say"

"Is there someone else because I'm fine with ruffling a few feathers. I'd even be open to have more company"

"Go back to Hell Lucifer. We are not sleeping with you"

Lucifer gapped at Dean then kept looking back and forth between him and Cas. Then he burst out laughing.

"A hunter and an angel! Could you think of a couple more strange than that"

"How about an angel and a demon? Or a human and a demon? I heard you have a thing for blonde female detectives"

This time Lucifer got in Dean's face, revealing his true face as a threat.

"Don't you dare mention her again. And stay away from her or there will be hell to pay"

"Easy tiger. I'll stay away from your girl if you stay away from Cas and that's the only deal I'll make with you. And just so I make myself clear: you come near Cas or touch him then I'm going to pay your lady a visit. Deal?"

Dean stuck his hand out and Lucifer hesitated before shaking it.

"You drive a hard bargain Mr Winchester but I accept. Farwell and hopefully I'll never have to see you again"

"The feeling's mutual. Let's get out of here Cas"

"Farewell Castiel. I'll see you very soon"

Those were Lucifer's last words before the elevator doors closed, and Dean was even more pissed off then when he stepped through them the first time. They had barely started moving before Dean slammed the stop button and pulled Cas into a rough, passionate kiss. Cas's only reaction was to kiss back and when he did that's when Dean began to remove their clothes, never breaking contact. They only broke away when Dean turned Cas around and forced him against the wall.

"Dean this is not the time or place for such things"

"Shut up Cas. That bastard wants you, wants to put his dirty devilish hands on you. He can't touch you but I can and I will"

With that Dean slide in and began to pound into Castiel, holding his hips in a tight grip. When Cas began to moan Dean reached around and began jacking him off, causing the moans to become louder and deeper.

"Dean!"

Dean smirked as Cas shouted his name as he came into his hand, which me made Cas clean up as Dean came in his tight hole. He stayed in place for a few minutes so Cas could enjoy being filled and he could enjoy being inside him. When Dean pulled out they both moaned from being so sensitive.

"You're mine Cas, no one else can have you"

"Why would I choose to be with anyone else? You're all I need Dean"

"Glad you understand. Now let's get out of here and go meet up with Sammy"

They got dressed and got the elevator going again. And when they stepped out they were surprised that the place was completely empty, not a soul in sight. Dean found this unsettling, it was too early for everyone to have gone home.

"I sent them away. No one can know what I'm about to do" a voiced spoke out as if reading his thoughts. They both whipped around to see Maze standing here holding a whip in one hand and a knife in the other.

"Mazikeen enough. We've done our business now let us leave"

"I'm sorry Castiel but my orders don't come from you. But don't worry, I won't hurt your pretty faces"

Using the whip she pulled Dean to her, punched him in the face and threw him into the piano which shatter on impact and Dean was in a daze. Cas moved to help him but he found himself with Maze's whip around his neck. It kept getting tighter and tighter until he couldn't breath and he passed out. Maze picked him up and carried him back towards Lucifer's.

That's the last thing Dean saw before he passed out.
