Martin propping me up on my knees is always a favorite of ours. It could be the visual for Martin but for me, it's the fact that it's a slow-burn that takes a good 30+ minutes before I begin breaking down.

I was ball gagged, crotch roped and on my knees while my elbows were crushed behind my back, ankles crossed and a rope securing me to the ceiling. I still had to maintain my balance though as it only helped to keep me in an upright position... and when Martin moved my shirt out of the way and clamped my nipples, things changed very quickly.
