I'm looking for any fics which have either of the boys (Sam or Dean, in this case; I'm not expecting any J2 to meet the criteria (if there is, feel free to rec)) are either born not fully human, such as one of them being half fairy, or half selkie, or something. Or, where one of the boys turn into something less than human.

I'm NOT talking about animal transformation fics, what I want is that they turn into something supernatural. Again; like a fairy, or a selkie, or even an incubus like the fic mentioned earlier on the community.

Also what I'm NOT looking for is ones where Sam or Dean turns evil due to demonic influences - unless there's a physical transformation involved, even if it's slight, I'm not interested. Angstier the better ^_^

I'm looking for either Gen or Wincest, no het unless you think it's something I absolutely have to read.

Sorry if I'm seeming nit-picky.
