Gen Girl!Sam genderswap

[lastpetalfalls.livejournal.com]

Hey people. So, I'm looking for a genderswap fic that I think was gen. Basically all I remember of it is Sam turning into a girl, and a particularly funny scene in which Sam needs to go toilet and says something about having to go frequently now that he has a small bladder, due to needing room for his uterus, fallopian tubes, and vagina, and Dean just doesn't want to hear about it. Hope it rings a bell, thanks in advanced for any help. Oh, and if anyone knows of any other girl!Sam fics, gen or wincest (not Sam born as a girl though), I'd love to read them :-) I've read the ones on Super-wiki. Thanks again
