specific request; Dean/Castiel; episode tag

[lansdel.livejournal.com]

Hello!

I've been looking for this one-shot for ages now, I'm pretty sure I'll spontaneously combust if I don't find it SOON. Please help.

What I remember:

It's a missing scene that takes place in the brothel when Dean takes Castiel there. Cas goes with Chastity and Dean goes with some other girl, and shortly after Chastity comes to Dean's room saying Cas was asking for him. Dean goes in and has to show Cas how the sexy stuff is done with a woman, and the two of them end up having sex, shoving the girl to the side, basically. (also, not Chastity after all)

I remember almost everything besides the title or the author.

Thanks in advance.
