specific girl!Dean/Cas

[softlikeatowel]

i remember once upon a time i read a fic where dean was, for some reason or another, turned into a girl. i'm pretty sure dean/cas was an established relationship, because as far as i recall it was just a pwp about how different it was for dean to have sex with cas as a woman instead of a man. i'm also pretty sure the whole thing happened in a motel bathroom.

wow this was really vague! any other not-always-a-girl!dean/cas fics would also be appreciated :)

eta: found!
