I forgot to point out that the idea of being killed by any old someone does nothing for me. The idea only excites me where it involves my loved partner, so perhaps it does indeed have to do more with submission in an extreme form, and not with death per se?

However, there is enough stuff on the web where snuff scenes are faked (and I am sure there is stuff circulated where it is really done - I think if you have the necessary amount of money, you can buy ANY service the human mind could come up with), some of them very convincing, and there apparently is a clientele for it.
Hubby knows some of those pages, and I think some guys (as the described Scot dom in a post further above) watch that as a sort of porn, nothing else.

In that regard, some of you might have seen the movie "Mute Witness", where a girl from Eastern Europe thinks she is participating in a regular porn movie, but it turns out she gets killed on purpose. It is apparent from her facial expressions that she had no idea where this would end.

I think something similar was shown in "8 mm", but I have not seen that one.

I have also once been shown some film material that was not for sale via the regular channels, and from the looks of it the women were middle-aged prostitutes, and the whole thing was located in what looked like the cliché Southern American secret service dungeon... There were no death scenes, but the women did not appear in any way willing or happy or aroused, there was very serious stuff done to them, and they were fixed in a way that disabled them from getting away or fight back... Mind you, I have seen stuff on Insex and the like, where extreme actions took place also, but it was always obvious the women did it voluntarily, and there were "after" scenes as well, where the ladies appeared quite relaxed to me...

I am sure stuff like this happens in real life.

I also understand why people, especially doms, who fantasize about being the active part in a snuff scene, will hesitate to admit it, for fearing to be called a potential serial killer etc., or getting a visit from the local authorities in case a woman around their area gets reported missing...

One last thing: I once spoke extensively with a guy from my city in a German chat room about that fantasy, and I was oh-so-pleased to have found someone who would not run sccreaming and call me nuts, but simply and matter-of-factly communicated with me about the risks and troubles and the details of my own particular fantasy.
However, when he asked my exact location and name, I grew a little cautious, and broke off the convo.

When I told this later to hubby, he said oh well, he knew that nick, and the guy behind it plus a few of his friends were actually looking for a woman with that sort of fantasy, and willing to fulfill it (apparently they had the means to cover it up and prevent them from having to face legal consequences).
But as no one ever met that guy in real life, and none of our regular chatters went missing, we had no way to check this out. (I was not willing to act as bait, neither would hubby have allowed that *g*).

So a word of caution to the subs on here: Please be aware who you share this particular fantasy with.
You don´t want to end up with a guy who is a little overeager in acting out your desires.
