This package contains one pose morph and a demo scene for blowjob.
The name of the morph is suck face4.
Just by using this morph and the open mouth morph, you can easily create a timeline blowjob animation.

Enjoy!
I will fix it as soon as the cause is still confirmed, however, in all my years of making morphs, I have never seen anything like this.
