They end up roleplaying I believe.

There's one where Justin is reading HP fanfiction and they end up playing headmaster and pupil. It's pretty much PWP. I think it's called Wanna play? but could be wrong. And I don't know the author either, so this is no help at all. :-(

All I know is that it's called "fanfiction" and when I printed it off years ago I didn't have the author's name on it. Grr.

Lol. You and I seem to have the same type of archiving skills.
I hope someone else can help.

Could you please add an update line to your post? Let people know you're still looking (presuming you never found it).
