Typically mega-sites offer you tons of content but not quality. At PremiumPass, I was surprised to find quality as well as a whole lot of content and even though the focus is not so much on pictures, I think most people prefer to see some hot videos anyway.
Your membership gets you access to 50 sites that come in 19 categories. Pretty much every major category is taken care of here so you can enjoy amateurs, anal sex, Asians, big tits, blonde babes, blowjobs, creampies, cumshots, Ebony erotica, gonzo scenarios, hung fellows, interracial action, lesbians, MILFs, orgies, pornstars, 18 to 20 year olds, threesome scenes and toys.
There should be something here to keep you busy no matter what you are in the mood for. I suppose the best way to give you an idea of what to expect is to focus on a few sites. Speaking generally, the sites have a similar design and layout as well as similar numbers of movies. The quality is excellent in the movies and if you want to make a movie search you can do so by genre, performer, sexual act and even physical attributes. This is a handy feature if you don't feel like browsing site by site.
I sampled TheExtremeNumber, a threesome site with 15 hot episodes. It was two babes on one lucky stunt cock and the episodes had some vid caps and a video the came as four short parts. There was also a full length option and the quality was superb in Windows Media, and quite good in MPEG. The vids were also offered in many formats compatible with portable devices.
I also checked out SweeterInside, an internal cumshot site with 12 scenes. These came with screen caps and great quality once again, with either the full scene or shorter clips that were downloadable in many formats, including PSP, iPod, and more. In general the sites all come with about 12 to 15 videos that are excellent quality.
Overall, you will get 600+ vids that you can download episodes over the many sites here. The main archive contains 2,292 movies and they come in all kinds of categories like the sub sites but are unique to the main site here.
Needless to say this site offers tons of content but unlike many mega-sites the quality is also there so really there is no excuse not to join up and start enjoying this hardcore material.
