I've seen this one, too.
Speaking on a personal basis only, it was not my cup of tea. It was done in the mines, was an "initiation" to the group, was in a darkened setting, she was filthy with coal dust, and was cast in a victim role.
Of course, it *was* Cherly Ladd. There's certainly value in that.
And I realize that in our spanking world that tastes run a wide gamut. So it might be received by others very well. She was standing up, leaning over, it was done as a paddling, so to speak, and it was more than one swat. I suppose one just has to watch it to judge.
