I'm looking for a fic I've read quite a few times already. The story is set pre-series and Dean is forced to prostitute himself to support himself and Sam while John's on a hunt. The thing in this fic is that Dean is convinced that John knows what he is doing and actually expects him to do it. John, naturally, is clueless but he eventually does find out. Sound familiar?

If you know fics with a similar premise -- basically, John finds out that Dean sells himself or suffers abuse -- please share them!
