The people who brought you pichunter have also got a site dedicated to movie clips - Cliphunter and it's just as good quality and trusted among porn users.
Cliphunter has a shit load of free porn movies because it's quite a few years old. New clips are added daily and you can find pretty much any niche here. On the homepage you'll see top rated movies and recently uploaded movies along with the hottest models. The advertising is kept to a minimum and is completely unobtrusive. Categories lets you fine tune your porn viewing with all of the usual options available such as big tits, teen and babe.
If you click on a movie you're given a huge video player. All this shit is for free! You can add to favourites, tag a pornstar, categorise the movie and more - most of the options will require a free account. The pornstars section is so useful if you know who you fancy wanking over. Simply use the A-Z to find the model you like and you're given all of her movies on the site. Again, all for free!
