I read a story a couple of years ago and I remember so much about it besides the title or author (of course I'd forget the most important part). I remember these things:
1) Jared was in his 20's, Jensen was roughly 12. Jensen called a helpline where Jared answered all of Jensen's sex questions which led to him telling Jensen to finger himself.
2) Jared lived with Chad MM? and had sex with Jensen for the first time in the basement while Jensen wore some kind of kiddy pyjamas.
3) Jensen used the excuse of looking after/feeding Jared's dog to see him/sleep with him.
4) Jared took Jensen on college tours when he was old enough and they were psyched because they could actually act like a couple in public.
5) At some point Jared talked to Mrs Ackles on the street of a block party.

I can't think of any other tags so hopefully I haven't missed anything.
