yes, we need it.
We need a tag to describe the act of expelling or pushing out an object from the vagina or rectum.
This can typically be identified by changes in the shape of the pussy or anus, along with the character's facial expression (e.g., straining or gritting teeth).
Perhaps it would be better to subdivide it further, such as bearing_down_face, bearing_down_pussy, or bearing_down_anus, but I'd like to hear additional opinions on this.
Do you support adding this new tag? Any other ideas or suggestions?
