Hentai games/Flash games

Flash games
The flash games aren't windows-dependent, so they don't have stupid stuff like region checking, or needing an emulator. If there isn't a link in the description, try searching on swfchan.

You can find a whole lot of hentai flash games on the porn category listing on swfchan (over 10 thousand). comdotgame also has a great adult section.
