I feel like there really isn't much material out there as far as good kinky yaoi goes. I've really only seen a few that were somewhat appealing. The ones that come to mind are Ai No Kusabi and Enzai. There was also this great little hentai series called Cool Devices that I used to enjoy several years ago. It would be great if I could find some yaoi similar to that. I figured this might be a good place to ask. Thanks in advance!
