Gang's unexpected visit - B/J caught in the act

[ancaangie.livejournal.com]

I've read this story some time ago, but I just can't remember the title or where I read it.
I remember that in this story Brian and Justin went away for a few days ( at the end of the story  it's revealed that they went to get married ) . When they came back, the gang came in to the loft without knocking and found them fucking on the sofa and Brian was bottoming. I remember that Gus (and probably JR) were with them also, and the girls were trying to cover their eyes. Oh, and Jen told Justin how could he do that, and he told her something like: do what mother? fucking in my own home with the door locked?

I've search the tags and stories but I couldn't find it, maybe someone knows this story.

Thanks in advance :)
