EUF.

Do you have the name or source of image #3? Looks like one of those Italian EUF scenes but this actress does not look familiar

I think all three are from the same film. That's Barbara Bouchet in the second photo, but I'm not sure about the other two. I don't know the name of the film, but I think it may be written on the caps. The clip is here on OCC for the white panty scene, but not the other ones.

You are correct. It's "Spaghetti a mezzanotte". It's on YouTube. Although the 3rd scene the woman undresses voluntarily because she is jealous that another woman is naked.

Sally Kellerman public EUF scene, from the film; Moving Violations. Sally plays a judge who's caught in a humiliating situation. The best EUF/ENFs are the ones that feature authority figures.

Man Show
 

From the Man Show, Angelica Gorges. Best quality I could get.

EUF? I'm not really sure what's going on here.

Two scenes featuring Beth Behrs from the television show; Two Broke Girls. The second scene was an almost perfect EUF, the only flaw being her panties. They should have chosen a more realistic style.

I think this is Trudie Goodwin as a plain clothed police constable when she and others were trying to arrest some bad guys. As I recall, this scene appeared in a pilot version of the UK TV Police drama called "the Bill". The pilot show was entitled "Woodentops". Both "the (old)Bill" and "Woodentops" are colloquial names for the Police here in the UK
