Are they good Christian girls?
Maybe, I don't know what they do in their off time.
However, that video is not near as racy as you want to portray it as being, nor is there a 'pole-dancing' element.
There are bikinis, but actually, for a bikini, they cover up quite a bit. No thongs in other words
I just don't see it as a big deal, just wish I had the body and the ability to move like that.
