How do I play the games on this site?

You search them on Flash game sites like newgrounds or ask around comments on how to acquire them , that's what i know.

If you want the F-Series games, you can simply type "F-Series Hentai" on Google and you should get plenty of them. If you want a particular website I would recommend wetpussygames and gamesofdesire.

try google

the download links for everything went under a while ago

but you should be able to find them somewhere

I think this belongs in the requests section.
