I don't know what 'kay' refers to with regard to Porn Kay, but I guess it doesn't matter all that much once you head on over and see what's on offer here. See, PornKay.com describes itself as 'the world's biggest porn search engine' with more than 10 million videos in their archive. Is it good? After giving it a decent use to find out for my faithful readers here at My Gay Sites, I'd say yeah, it's kay.
Go ahead and type in a keyword you like: twinks, bears or college bareback: whatever your poison, it seems as if PornKay.com will have some material for you to enjoy. Note that sadly, it doesn't appear as if Porn Kay has specific filtering available for gay content, so you will need to specify that it's what you're interested in by using the keyword 'gay'. The results are pretty comprehensive and can be sorted by a number of different user-defined requirements as well as filtered based on length, HD status and upload date. Oh, one final note: it has straight ads for gay searches, which is a little funny.
