NudeVista could be considered the Google of porn tube sites. It lets you search for anything you want, and gives you results from tons of different websites.
If you want numbers, Nudevista.com states that you can search through more than 25 million tube videos, close to 2 million photo galleries and look up over 40,000 adult models. You'll be able to find all sorts of content from erotic to utterly bizarre featuring guys, girls, and shemales. There's everything from two or three-minute clips to full porn movies that pass the one hour mark. You'll also be able to find thousands of HD videos.
Since each result can take you to a different porn site, it's good to have thumbs that tell you exactly where the content is located. There's also other useful information like model name, title, tags, and date of upload. Since nothing is hosted on NudeVista, downloads, adjusting streaming quality and the number of ads will depend on the site that you are taken to.
All in all, this website is pretty simple when it comes to looks and doesn't have many ads, but offers good search functions. You can filter videos by length, the background color of a website, popularity, and show only HD videos. There's also the option to check orientations (gay, straight, tranny, bizarre), and filter results by when they were published. Moreover, there's a separate section for tubes and pictures, a directory of tags, an impressive model index with lots of options, and finally an advanced search.
NudeVista.com is for those that don't know which free tube site to head to, or just want to dig through millions of videos and pictures in one place while using powerful search tools and an impressive model index.
