Looking for two fics I haven't been able to find searching the archives of posts:

1) The story opens with Dean looking for Sam - Sam is in high school, and for the last month he has been openly rebellious, doing things out of character for Sam.  Dean finds him at a party, openly getting high while a blond kid is nuzzling his crotch.  Dean drags him out of the party and they fight in the Impala.  Dean and Sam have had the occasional sexual encounter, but Dean feels so guilty in between them that he pretends they never happened and pushes Sam away.  Sam takes control and lets Dean know that he doesn't get to decide when they are intimate, and he doesn't get to pretend it never happens.  It ends with them having sex on the hood of the Impala. 
FOUND - in the comments!

2) I've found some great character bleed stories in previous searches, but one specific one, the first of that type I read, I can't find.  It was a Dean/Jensen character bleed story, and it took place in Jensen's trailer.  It was NC-17.  I believe there was actually a Sam/Jared follow up it, but I may be mistaken.

Thanks in advance for any help!
