Author's Note: This is my first time writing a Cas/Lucifer Slash, so forgive me if it sucks. As usual, any reviews are appreciated! Oh and do tell me if want me to write a multi-chapter fic. I have this plot that is ready to be written but I lack a certain amount of encouragement so tell me ok .

Disclaimer: I don't own Supernatural and any of its characters, although if I do own it let's jut say that it will be very interesting (evil smirk).

Heavenly Brother

Lucifer was amused. Very amused. For the first time since he was cast down to the pit, he never knew that there would be another angel that would show any sign of defiance except for himself.

Clearly he was wrong to assume this, as he was looking at one of his brothers tied and bound inside a ring of holy fire, insolence clear in the vessel's features.

"Castiel, brother, why do you keep fighting me? You know it is useless sooner or later. Sam Winchester will say yes, and if I know Michael he will make Dean say yes too."

"I will never let you do it! I will stop you before you do!" Castiel said his voice gruff and with a fury only belonging to those of the heavenly host.

"You?" Lucifer smiled serenely.

"I do not have the power to stop you, but God does, and when I find him you will be reduced to a pile of ash." Castiel said calmly but the anger was still there.

"God is dead, my brother. If not, he simply does not care anymore, this planet is slowly dying." .

Then, without warning, Lucifer parted the ring of the holy flame and he stepped inside as he slowly bent down and captured Castiel with a searing kiss.

Castiel wanted to fight back but his limbs were bound by Enochian chains. He couldn't break it and he was starting to give in but his resolve kept him from submitting to Lucifer's will. Lucifer then pulled away and broke the kiss, his expression calm and serene that anyone could easily fall for him.

And with a flutter of wings, he was gone. The ring of holy flame containing Castiel evaporated soon after. And the magic surrounding the chains that bound him disappeared. With a little effort, he quickly broke it, straightening up as he turned to leave.

"You are wrong. I will find Father and when I do it, your days will end." Then Castiel left.
