Specific fic: Dean/Sam, girl!Sam, canon

[ohwillothewisp.livejournal.com]

I read this story about three or four years ago I think. I wasn't reading wincest at the time so I didn't save it and now I wish I had. Here's what I remember:

1. It was a canon story set before season four (I think).

2. Sam was (cursed?) and became a girl. Sam and Dean were not in a relationship before that but got together over the course of the story.

3. In the beginning Sam came out of the bathroom as a girl and his/her jeans no longer fit over her hips. Dean was freaked but Sam said he/she had always been a girl and Dean's "sister" and Dean started to wonder if there was something wrong with HIM. Sam was only messing with Dean, he really had been turned into a girl.

4. Dean would hold Sam while she cried (I think at one point they were spooning with Dean on as the big spoon.)

4. In the end Sam admitted that he had always had feelings for Dean. Dean didn't tell Sam but it was revealed that Dean only started to fall in love with Sam after he became a girl.

I really hope someone can help me find this.
