Based on the work I did with the block & tackle, I set up to shoot a video in which the knot I planned to use to release myself was out of reach and the weight, with the help of the pulley system, was too much for me to overcome. The force that was pulling on my wrists was countered by the force of the rope pulling the other direction on my genitals. I was unable to move, and unable to call for help. Nobody was going to find me where I was tied, and escape was impossible.
The good news is that you get to see all this play out in a great video, and I did survive to tell the story. On that note, if there are any self-bondagers out there, I should warn you that I took a lot of time setting this up and making sure I had an actual escape. I also found a spotter to help me out if things did not go as planned. Being caught in this bondage for even a few hours would have been anguish beyond the point of being fun.
