This is old, and I barely knew what I was doing :P But i somehow managed. You can tweak the facial expressions within the script, add on, do whatever you want with this. Enjoy!

You'll want dollmaster
DollMaster plugin written by VamDeluxe Fixed by vamX

I created two Dollmaster Personas for  male voices. Just put these folders  in  scripts/vamdelux/dollmaster/assets/personas and they will show up on the persona selection in game.

Note: put the breathing_panting audio file in  SFX folder and overwrite. This is a male panting loop

I have made some changes to the filenames and persona scripts to allow for both males to have a persona when adding the dollmaster script to both of them. See video attached for a sample of how it works.
