I don't know if this is the right forum to post this on or not but I need your help. A while ago I listened to a video narration of a story that is about a guy getting tortured and after he shouts a safe word and the. The torturer stops. The torture turns out to be for a snuf film. This story was also made into a short movie. I can't remember the name of the story. Do any of you know a story like this and if you do what is it's name.
