#future!castiel

“I like past you,” he says with a smirk, and you’re still having trouble reconciling this scruffy human before you with the angel from your own timeline. 

You take in the the beard, the hardened look in his once vibrant blue eyes, the sarcastic smile that does nothing to soften his expression, and you decide that whatever happened to make this future the way it is, you want no part of it.

“Cas,” you say quietly, stepping forward to place your hands on his cheeks. “What happened to you?”

I think this song is quite perfect for future!Cas, but only for the decadent version of him

“Castiel!” Cas’ voice sounds panicked in a way Dean’s never heard it, and he wants to get up and see what’s wrong, comfort him and maybe fuck him a little to calm him down - no, that’s his body talking, right? Shit, he can’t think - “Castiel! Please, please get down here. Something’s wrong with Dean!”

It’s funny, Dean thinks in a swift, lucid moment, that Cas only prays without the thinly mocking or sarcastic tone when something’s wrong. Luckily Castiel can’t tell either way.

“What’s the matter with him?” Cas demands, and Dean shivers and whines because fuck, it’s freezing now. Means Castiel must have shown up - oh, yeah, and he’s really cold, too. Bet that’ll feel awesome, ‘cause Dean’s about ninety-nine percent sure he has a fever of some kind.

“He’s in Heat,” Castiel replies coolly, like it’s the only logical explanation.

“Heat?!” Cas replies, and Dean can just imagine him - wide-eyed, shaking his head, arms thrown out to either side of him. “Like a fucking animal?”

There’s a laugh, and a cold hand against Dean’s forehead and damn, that feels really good. He turns his face into it with another plaintive moan. “I suppose if you want to see it that way, yes,” he says. “I’ve made Dean able to conceive. He has always wanted a family, and as a man lying with men, we cannot give him one. I thought this was the best option.”

“You could’ve fucking warned us! I thought he was sick. I thought he was…" Dying. Dean doesn’t hear the word, but he can figure out what Cas was going to say, and he reaches out blindly, wanting to pull him close and comfort him. The scent of apple and vanilla hits his nose and Dean pulls Cas into his arms, soaking in his warmth and the chill of the God’s presence, and it balances out so wonderfully.

“I didn’t know when it would take effect,” Castiel says, somewhat defensively. 

“Cas,” Dean complains, reaching out for the God as well and sighing when Castiel’s hand returns to his hair. “Please,” he grits out, not even sure what he wants or needs anymore, the clash of warmth and cold air is making him dizzy and his body feels like it’s on fire and frozen, empty at the same time.

“You will lay with him, Castiel,” the new God says, his hand leaving Dean’s forehead and earning a soft whine from the Hunter. “I have changed your body as well to ease and quicken the process.”

“You should be here too,” Cas argues, but he’s pulling Dean close and he’s so warm and smells so nice that Dean goes without complaint.

“I have things I must take care of - I have been preparing a nest for Dean to move to once he becomes pregnant. And…paternity is less of a concern to me than it is to humans.” A pause. “I know Dean loves me. I don’t need to father his child as prove of that.”
