Mock Surprise
 

Imagine you come across a girl in some state of undress. However, she doesn't actually mind you seeing her like that. Where a true ENF pose would have her trying to cover herself with both hands, instead she makes a face to act "surprised" (such as by bringing her hand to cover her open mouth). And crucially, she doesn't actually cover anything we want to see. ;)

I'm looking for pictures like that. Here are some of my own examples, post your own if you have them!

Does the balongdansen count?
 

It's the 'oh no! How on earth did I end up in this completely voluntary situation! How awful that I'm almost completely naked in front of my entire village!' face that does it for me...

first one to come to mind
