@Salzka - I refer to your response to my last image.
I have absolutely no doubt that the position is uncomfortable to the models. The point is that, to me at least, the position looks fantastic.
It looks kinky and the good models, like those involved, make it look like they are having a great time, even though I a certain it is hard work for them.
In the end, this sort of site is about fantasy sex. And that is a fantasy sex position which makes it appealing, at least to me.
Apart from that, I like your two examples of good positions.
