The Japanese have a leg up on all the sicko shit. From link below:

"Goukan pure - ("rape play") the most famous exmple of this is stalker - the name of a popular magazine which is exactly what the title says. photos of a woman going to work, coming home, photos through her window, and THEN photos of goukan pure. unlike the hidden-camera porno, this is NOT real (hence the 'pure'): it's some paid AV actress playing the part of an average office worker. in fact, goukan is considered 'normal' enough that famous AV actresses will do rape scenes. Along with bukkake, cosplay, and yuri, it's part of the standard repitoire of many popular mainstream idols. And let's not forget the 'KARATE GIRLS VS. RAPE TEAM' videos"
