There is 2 versions:
One with a script that make your character open it's mouth when equiping the tongue, keep in mind this version will also overwrite any femalehead.tri and mouthhumanf.tri you have in your folder.(if you installed a mod that modifies those files ofc)

And one without it, so it means you will need to open you character mouth using console commands/other mods.
