Well, I don't really have links to specific stories for you, but any fic by phantisma and rei_c fit into your request. Just have a look at their master fic lists and see if there are any that sound good to you. I like all of their stories so I can't really single one out, except maybe the 5d5d verse by rei_c.
*argh* edited to say that I totally missed your request is only for J2. Rei_c sadly only has a one or two rps stories alas they are really awesome too.
