looking for specific fisting story

[elvenfixation.livejournal.com]

I'm looking for a fic that I'm pretty sure I read on bjfic.net, but I can't find it now. I know it's a one-shot and it might be post-513.

It starts with Brian and Justin in the back room, I think...they're both pretty high and Brian starts fisting Justin. But afterwards he gets upset because he thinks he was too rough and he starts blaming himself, and he's angry that Justin let him do it...

I remember there's line toward the end while they're arguing about what happened where Justin's telling Brian it's not his fault; that it was what Justin wanted...he says something like "...it's my ass and I decide what happens to it."

Is this familiar to anyone? Thanks in advance.

Edit: Story found. Link is in the comments.
