NylonButterfly offers 31 sets of high-res photos and all of them are incredibly well lit and crisp. You'll definitely want to have these pics in your personal stash and you can download them in Zip files.
I had difficulty viewing and downloading the movies at first. I decided to use the online support, but I didn't find that it was very supportive. In fact, I was told to press the button or right click and save the movie. Uh, yeah. Support, indeed. There are only six excellent-quality AVI videos, but they're not offered as uninterrupted features. Instead, there are three clips per movie. The quality looks a bit stretched, as if the people are a bit thinner than they would be in reality, but it didn't detract too much from the hardcore.
While there are lots of ripped stockings and nylon worship on the site, especially in the photo sets, the content is focused on hardcore threesomes where one horny babe takes on two eager cocks. I wouldn't call it a site for a person with a true nylon fetish, but certainly it's a site for those interested in blending the feel of nylon and the look of gorgeous babes in stockings with hardcore sex.
Updates are where this site really seems to go off the rails because the content has not grown at all in the past couple years. This is definitely disappointing because there isn't that much material to work with in the first place. You may think they are updating because the dates are current, but they are just changing them, not adding new content.
Overall, Nylon Butterfly seems like a site with potential. However, with so little content and no updating, the potential for good seems to have fallen way short and if you are really looking for hardcore sex and nylons this isn't the place to find it.
