The world of MSR fanfic has many wonderful stories about the "first time." Here's one about the changes and adjustments that follow. Mulder and Scully suffer through their own insecurities as they take on the Consortium. Some jealousy for Mulder.
Kel isn't one of those author's names that you hear spoken of reverently in the XF fanfic world, but by the gods she can write some intricate plots. Not only that, but this one is interlaced with the kind of humour that almost borders on the ridiculous at times, and just makes you feel good.
There are bonus cameos from Bill Clinton, Al Gore, and Newt Gingrich to add to the fun.
