Castiel uses a female vessel to look over Dean for a night, but they have a one night stand because of a drink that has an elixir of sorts mixed in. This new version of Cas tries to hide from Dean that it was him he had sex with, because now he can't get back to his old vessel. Oh crap, and now he's pregnant and he doesn't know. [pregnant!Cas, platonic (?) Destiel, mpreg later, s8]

Answered this prompt: "Supernatural, Castiel, Cas is confused why men keep honking their horns when he is in a female vessel." - Got kinda schmoopy at the end there. Reviews are love! Title taken from "Time After Time."

Castiel was a broken angel when Lucifer finally won on Earth. So when God gives him the chance to go back and stop it from happening, he was quick to agree. There was one catch...he would have to abandon his gender and become female to avoid a paradox. Now Castielle is on a mission from god to save the Winchesters and hopefully make things right between her and Dean. Destiel!

When castiel's vessel changes gender, How will Dean and everyone else react to the sight of Cas in female form. will Dean start to miss Cas' male vessel? or will the new female form of cas be easier for his emotions to deal with, please review xxx

Dean/F!Castiel, Meg/F!Castiel, Sam/Ruby.

Castiel's vessel is Jenny, not Jimmy. Being a human female comes with things Castiel is unaccustomed to. And it's awkward for everyone. But especially for Dean. Genderbent!NewlyHuman!Castiel Set in Season 9! But AU because Sam isn't possessed by Gadreel. Could be Destiel, if you squint.
