mouth not staying open during sexlab blowjob scene

[blaqk_soul]

As the title says, whenever a blowjob scene occurs, my character doesn't keep her mouth open while blowing. It will stay open for the first few seconds,  but then open and closes as if she's moaning. Haven't found a fix for this at all.

 

Any help would be amazing!

I use Vanity Mirror 2 to manually change the character's expression (not sure it matters what thing I change), exit, then use it again. to set the expression back to normal. This is not a permanent fix, obviously. Others will no doubt post with more permanent solutions. I am far from an expert at debugging mod issues.
