I'll attach my collection from various sources (I kept the names of the sources in the folders' names).
The way it works is simply extract the main folder (Expressions), and add it as a Base Directory in daz (from the Content Library panel), and you are good to go. Or, if you know what you are doing, you can rename it, move it to a different place before adding it, etc.
There are only duf files here, no morphs, and almost all expressions work.
My personal favorites are in "custom/pleasure/Xameva_FacesOfO_Edge", I also like the ones in "for her/pleasure".
Again, you may already have these expressions, this is just my way of grouping them.
Expressions1 has : kiss/pleasure/suck
Expressions2 has : for her/for him
Expressions3 has : forced
If you need/want the name of a source, let me know.
