old school first time wincest fic

Howdy.

I'm looking for a story written in the first year or two of spn fandom that goes something like:

Sam and Dean on the road, business as usual. but somehow Dean finds out that Sam experimented with guys in college and begins to pester him about it, wanting details and stuff and Sam will not comply or give in to the taunts, until he finally does and has his way with Dean and very, almost clinically if I recall. Sam is very dead calm and toppy and afterwards they're both kind of left in an awkward place. I wouldn't call it dark fic by any stretch, but it's certainly not schmoopy.

I hope this rings a bell with someone. It's been a very long time since I read this and so it's also possible that I have their roles reversed and it's in fact Dean who makes the admission and Sam becomes fixated on the idea. I'm not sure, but I'm pretty certain it's the first scenario. Help!
