I actually prefer EUF to ENF. Not exactly sure why. A possible theory is that when a woman a nude, she might be able to cover everything. With underwear, it's harder. There's always going to be something exposed, and when the underwear is bigger (like "granny panties" or slips), it's impossible. Seeing a woman just have her hands dart around her body trying in vain to cover it all. It's just so awesome. So I figured it's only fair that I make some contributions to this thread.

There are more clips I've found over the years, but I'll leave it here for now. Hope you enjoy!
