I have read one like this and can't for the life of me remember the title..

Description, as much as I recall--The story goes pretty close to the episode, with the exception of Wincest.  I remember Sam getting jealous of the woman kissing Dean, he assures Sam it meant nothing.  Sam was frantic to get him back (as I would be).

Again, I know this is very vague,

Thanks in advance for all your help :),
