The girls here are European, slim, sexy and tend to be young 20s. They are certainly all very hot and get involved in some very romantic sex scenes. These scenes are different from your normal gratuitous hardcore because of the way they are filmed. There is great use of back lighting, and sensual filming, almost like watching a David Bailey photograph that's moving, and that becomes hardcore. They are sensitive and, well, natural scenes, hence the name I guess.

The members' area design at 21Naturals, by contrast, is modern and tight and functional. It's got just about everything you will ever need to make your time as a member run smoothly and be memorable. You will find a list of all the extras and bonuses on the left hand side of you page and clicking titles opens longer lists of all the sites; you click one to enter it and you go straight there. You also find a top menu that gives you access to things like external cam sites and the like, but which also takes you home, to the scenes, the model index and a place where you can fiddle with your viewing settings and preferences. There you also see that you have credits and that you need to buy credits to download certain films.

These films are shown in large sample shots on the index pages and when you click these you arrive at the viewing page for that scene. You are able to stream them as part of your membership but you will need to purchase them if you want to download and keep them; at least, that applied to certain scenes. Others I was able to download without having to pay extra.

The scenes come with the standard interactive options such as rates and comments, though you have to rate before you can comment. There is also the add to favourites function to use and links to the mobile versions of scenes and the photos. These photos come with online viewing and with two choices of zip file downloads, where you can select high resolution or standard sizes. Photos come with basic navigation tools so you can browse through one by one.

Clicking to the model index I found it covered the whole of the network, some 3,441 models. You can rate and comment on the girls, and there are linked tag words to help you find more of the same, but I didn't find much information about them, not a lot of stats. I also found that when I clicked the Scenes link in the top menu I came to the full collection of scenes for the network, an impressive 10,000 + in total. But I found it hard to stay within 21 Naturals, I had to use my back button to go back and find the index pages of videos. Or else go to the main Home page and then select my site from the left list.

I found that the site not only held good quality content, and was updating every week, but was also fun to use once you'd got used to the navigation system. There are lots of extra functions and things to experiment with and a help forum if you have any trouble.
