AdultCrawl is a search and crawl engine that specialises in free adult sites and galleries. No more time-consuming searches to find a few free pictures or a sample video or two. AdultCrawl boasts an average of 30 new sites and 200 new galleries a day added to their directory - that's enough to keep you out of trouble!
The directory is laid out in helpful sections - galleries, sites and a list of different genres that span everything from anal, cumshots and fisting to lesbians, nudists and teens. There are also a few more unusual categories such as machines, bath, 'oiled' and - most bizarrely - fitness! Well, I suppose your wrist will be getting a good work out.
The only downside to AdultCrawl is that there is no search facility so if you're looking for something more specific than the genres featured then you might be doing a bit of crawling through a section or two yourself to find it. However, this is a free search engine and provides a service that I'm sure most of us require from time to time! Definitely worth a visit.
