Specific boys raised seperately; Dean on streets/prostitute and Sam with a nice family

[velvetmagras.livejournal.com]

Hi all, this is an older fic and I'm really vague on the details.

Dean and Sam not raised together. Probably on ff.net. Dean was a prostitute and Sam was being raised by a nice middle class family. I think they had the opportunity to take Dean at the same time but chose not to. At the start of the fic I think Dean somehow escaped/ran away from a 'john' in a hotel with Sam's help? Sam and his family were staying in the hotel too which was really lucky as the bad guy was a planning to kill (he was a serial killer?) Dean. I think they both realise they're long lost brothers. Sam talks his parents into taking Dean back home with them and letting Dean stay with them. I think another (or the same) serial killer/demon starts tracking Dean. Also Dean has a lot of trouble fitting in and Sam's mum has issues with Dean too (possibly guilt? She might have been the one to say no to adopting Dean in the first place). That's all I have. So, thanks in advance.
