Beheading does nothing for me at all, but i can and regularly do cum to burning videos. The twisted thing is that I always picture myself as the person burning, and often enhance the experience by roasting my butt, balls, and cock, over an open fire. I've burnt myself to the point of blisters and even open burns appear.
Burning at the stake over a wood fire is my favorite, but those are few and far between, so I settle for immolation and burning lynchings with the victim doused with fuel then burnt, of which there are many samples around the web. I also don't care if the victim is male or female, as long as the fire does its work. I do prefer that the victims be nude.
I have been known to enjoy hanging videos, especially if the victim is nude.
