Kinbaku Ouji (緊縛王子) - L/Light Death Note game by Orange Pekoe. Hardcore fetish yaoi, including rape, urination, bondage, and foodplay.
There is no English translation patch, but the site tegmentum.net used to have a full English translation consisting of screenshots of the game with English subtitles. This torrent includes both the full Japanese game (change your system locale to Japanese before you extract the files and try to play the game!) and the translated English images.
