While leathergloveboy was here, I wanted to experiment. I hadnâ€™t put my five-point shackles on someone backward before. Why not try it out? So, I had him wear his rubber singlet, blindfolded him, and then put him into the shackles. Once in the shackles, I strapped him down to the futon, to further limit his movement. Iâ€™d say it worked quite well. I shortened some of the chain with padlock and clip, making it much tighter without putting too much pressure on the neck.
