This - this link right here - is a fanfic called "Birthday Vacation", written by a longtime Leftover Soup reader who goes by Jim.

That link is the work-safe version, there are X rated scenes that go alongside it all simultaneous-like that I'm linking with these words over here, or if you want to read the entire thing in chronological order you can click here.

"Birthday Vacation" features the character John Brown (not to be confused with Nicole's husband John Penn). John Brown was previously introduced in "Operation: Break Out Make Out", which is SFW and which I'm linking over here. He also later appeared in a decidedly not SFW piece called, simply, "The Game" which I'm going to link over here.

And all of those are PDFs, because they're freaking long.
