Sexually im pretty submissive and a total bottom..most of the time. But I do think it would be hot to have two other guys, one to kill with, and another to be the victim..or maybe a few victims. Id want them all to be willing victims though to get the most amount of intimacy out of it. Having a person literally give you their body,soul,and last seconds of life is such a hot,intimate thing that I want shared by both the victim and killer. First id want to have days of group sex before the actually killing/killings. Id love to be fucking a guy and have my accomplice tie a rope around his neck and strangle him, or have him laying with a slit throat, both ways as I fuck him and after being castrated. Id want him to have a slow death as I fuck him. Then id want to get fucked by my accomplice. It would also be hot to have the victim fucking me and right as he cums he lets my partner and I know so my partner can shoot him in the head so the last thing he felt was an orgasm inside of me.
If it is multiple victims feeding one victim to another would also be hot and even feeding part of a victim to him self before the actual killing.
