Fetish Fuel is a troper tales subcategory, it's nothing more than "this troper is turned on by xy". Anything can be Fetish Fuel for someone.
But the OP was asking about Fetish-Fuel Future, not Fetish Fuel.
In response to the OP: I don't know, and haven't read the work in question, but what you describe doesn't sound like Fetish-Fuel Future to me.
Okay, then I guess I'll say that a Fetish-Fuel Future is a future where Everybody Has Lots of Sex and the author's getting off on it. We don't seem to have a trope for a future where Everybody Has Lots of Sex and the author's not getting off on it (which, come to think of it, also describes Brave New World), so I guess this example's just Everybody Has Lots of Sex.
Edit: Wait, just looked more closely at the actual trope description rather than the examples. Apparently it only counts if it's weird sex, with normal sex not fitting the trope, so this wasn't anywhere near that anyways. Forget it, forget it.

That's Feo . . . He's a disgusting, mysoginistic, paedophilic asshat who moonlights as a shitty writer—Something Awful

. . . if the author seems to be trying to disgust the reader with it? The case in question is The Worthing Saga, where the narration expresses what seems to be contempt for a society that's horribly disgusted by videos of urination but thinks videos of sex are perfectly fine. (Ignore for a moment whether you're horribly disgusted by videos of urination—the point here is that the writer doesn't seem to be getting off on the sex depicted.)
