So I went and searched for Lyra+Human+mature+sex tags, then added stuff that still looked like maybe they were clopfics. Surprisingly a lot of stuff I skipped over even with all of those tags. I haven't read any of these to be sure, so if you find something that does not contain any Lyra on human fucking in it, post here. I'll give the story more than the cursory glance I've devoted so far and remove the unfitting stuff.

A night in the life of a nympho. I don't think that one belongs.

On what grounds? I just gave it a quick skim. There was indeed some explicit sex involving humanized Lyra and humanized Bon Bon.

It has Lyra having sex with a human. The standards for this group are not very complicated.

Oh, it doesn't matter that she's human as well? Alright, my mistake.
