In regards to the one where Sam stays, silverkit did one that I thought was utterly heartbreaking. It goes just as you say it would.

It IS a fantastic fic, no question!

But.. anyone who hasn't read it should brace themselves for an incomplete ending..

I'm quite a fan of toppy, agressive Dean. Some of my personal faves you might really like (watch out for kinks though, especially bondage - it seems agressive Dean is a kinky little shit!):

I have a bottom!Sam fic list here (http://moonfairyhime.livejournal.com/304039.html).

this is one of my fav aggressive top!Deans:

Honey (http://aeroport-art.livejournal.com/12728.html) by aeroport art (http://aeroport-art.livejournal.com/)

This is more "Dean instigates" than "Dean tops," but Exact Change (http://dontyouwaitup.livejournal.com/131671.html), by dontyouwaitup, is a fantastic story.

For top!Dean:

And the Highway Lines Pass By (http://philalethia.livejournal.com/190703.html), by philalethia
All the stories in rei_c's "Five Districts, Five Drugs" series. My favorites are That Phantom World So Fair (http://rei-c.livejournal.com/678549.html) and Blue Like Heaven (http://rei-c.livejournal.com/703539.html).
Balisong; No Murmur (http://assignations.org/spn/balisong.html) and Be Still (http://wordsmiths.net/Maygra/bestill.html), by maygra (warning: knifeplay in both)
