in free sex mode with the large penis, is it possible for the girls to take it all the way in the mouth? o matter how hard I try it only seems to hit the lips.

Yes, its too big for her mouth. Future version will contain a long cock for deep-throat action.

Thanks, but it would be good if she would gag, go red in the face, squint even mascara run.

I believe the dev's are working on improving those features. You should see these as the patches roll out over time.
