Evil!Sam becomes good/ Falls in love with Dean

[d666lisa.livejournal.com]

Hi I've just finished reading the amazing Captured By The Game where the yellow eyed demon sends evil!Sam undercover to befriend Dean and I was just wondering if there were any similar stories out there.
I've tried searching the evil!Sam tag and there are some brilliant stories but they all seem to have Dean being used as a sex slave or being controlled by Sam.
I want Sam to genuinely love or at least respect Dean, possibly to the point where Dean ends up turning him good again. Any rating or pairing is fine, thanks in advance for your help :)
