I'm not sure about this one, pus*y positions seems ok, at least in scene version I posted & added as jeanette_sex_c in the last working build. Is the position different in your file? However, pus*y drawing seems a bit strange to me, but it was most likely Crow's intention because he just drawn it like that.
If you want to change pu*sy position by one constant offset in all sex sequence frames, you don't need to change position in all frames, you can change just position of pus*y drawing shape in the sprite that is added and moved in sex sequence.
I'm a bit concerned that you seems to put all your time in struggling with this one scene. It looks good enough with your drawings added. There are other things I need your help with too.
Regarding the scene work, I have a challenging task for next year. Vixxxen blowjob scene. Crow created a file with scene concept, drawn all body parts but haven't done animation. It has 22 body parts to move in a sequence so it's no way to have it in upcoming v0.671
