No, iTeens aren't a breed of fresh-faced babes created by Apple. It's a hardcore site focusing mainly on teen hotties and all the nasty things they can do. However, many of the scenes come from another site called Teens For Cash, which is a hardcore reality site featuring hot teens getting money thrown at them to get naked and fuck.
iTeens has several other kinds of scenarios too. There are FFM and lesbian threesomes and foursomes. You'll see babes getting picked up on the street and fucked in the back of a van and there's plenty of anal, interracial and cock sucking. The main similarity in all the flicks is that the female performers can pass for teens.
You can find some featured episodes on the homepage or you can just click on "view all site episodes" to get to the entire collection. The content is also available on many of the network's other sites, which you get as a bonus, so prep yourself to see some repeats. Right now there are 646 movies of teens getting down and dirty.
You must be thinking, "Wow, that's a shitload of videos to add to my porn library!" but hold your horses, bucko. You can only save 15 of these videos in a 30-day period. You'll have to be content to stream the rest of them in Flash. The ones you can download, however, provide HD playback. You will receive 15 more downloads each month and you'll get 50 downloads if you join for a year.
While you'll get many nice-looking photos with every movie, some only give you video captures, so you're looking at about 550 photo sets. Regardless of what kind of image it is, you can save all the sets in Zip files. You can leave comments and rate the scenes and add anything you really like to a favorites section.
In terms of those extra sites, they come from Pink Visual Pass and you can peruse 30 that cover a wide variety of niches, like MILFs, lesbians, reality sex, orgies and DPs. Some of them are Backseat Bangers, Her First Big Cock and Black Cocks White Sluts. There are also video feeds.
iTeens actually has about double the content than Teens For Cash, so if you are going for quantity, this is the one you should go with. All that said, I'm not super fond of the download limit and the fact that the site shares all of its teen porn across the network.
