WorldMature is a hardcore site featuring horny, experienced older women and damn lucky, studly men. The variety in the women's ages is quite expansive. I saw some yummy mummies and some much older women who were too old to simply be called cougars.
The pictures section of the site consists of about 250 photo shoots. While most of them are solo sets, there are plenty of hardcore fucking ones too. The video section isn't as large, but does have 56 videos divided up into clips (many have a full-length download option). The clips download in great-quality Windows Media format and the newest ones have superb-quality playback. The site is based in Russia, so don't be surprised to hear Russian TV or radio in the background.
Overall, the videos look great, the broads come in a nice variety of mature ages and the amount of content is good. Updating is a problem, though, and it has been many months since they uploaded anything to the site. In fact, the news and update sections are empty and it doesn't look like anything new is going to be added any time soon.
Your membership also gets you access to two other mature sites (Mature Lessons and Mature Debutants) and hundreds of photo sites and feeds. Given all that, it might be worth checking out, but more full-length World Mature scenes would be appreciated.
