That scene came out of a soft porn japanese movie back in 1995. She tempuraed her hand and deep fried it then took a bite out of it before she sliced off her pu$$y lips than proceeded to eat her eyeball.
Its some horror show about a guy who comes up with a super painkiller, the more pain you feel, the better you feel. That gal in the video is just one of the 3 victims, one of them pierced herself to death. The last one, had sex with him, strangely with no ill effects.
