See, there's almost a great gag in that site title, but they spoiled it by calling it PopPorno instead of PopPorn. I bet the PopPorn domain name was taken though. Close but no cigar.
The marvellous layout and presentation on this site make you think for a bit that you're on the verge of something sparklingly innovative, but unfortunately not. This is a pretty straighforward teens site thankfully clear of the usual teen porn cliches and instead showcasing the looks of the almost always stunning girls on show.
Sometimes I wonder if sites forget to showcase the sheer good looks of the talent at their disposal, like that's not enough, but for me it can be. A pretty girl showing her stunning body will often be about enough for me. The currently sparse but steadily growing PopPorno allows its talent to showcase their wares in depth before plunging them into a seperate gallery of the expected hardcore antics.
Unique it most certainly isn't, but it's approaching the teen niche in entirely the right way and has a good future - as long as it updates soon, that is. That month's gap since the last update is a concern.
