Hi, It depends on how many sites you want to block.
If it is only a handful then you could use NBAR and class maps as outlined below:

The proper way to do this would be to use the FW feature set and the urlfilter configurations with WebSense or N2H2 (or whatever it's called now). There is a way on certain IOS versions to use the urlfilter and map them manually. It should actually work on all of them but it doesn't. I'll go into that if you are interested. But a manual configuration like that can get unwieldy if you think about restricting not only the typical search sites, news sites, social networking sites, and such but also the porn sites. It will turn into a big config if you don't have an external filter server.
