Tit torture with nipple clamps - self bondage scenario

(Note: I have a short video of this scenario. This was more or less to see if it was possible, so I did it over a short distance. It only took me three minutes to reach the key, but if you want to see it, just ask. Then you have to imagine me in this position for 15-20 minutes :)

Here is a scenario I performed last night. Hope it can be of inspiration or at least entertaining to read.

First the setup. I choose the biggest room in my appartment where I attached a piece of rope to a solid object in one end of the room, a little over two meters from the floor. Then I ran that rope across the room where I attached it close to the ceiling in the other end. On that rope I had put a ring that could slide easily from one end to the other. To the ring I attached a rubber band and then I attached the rubber band to a pair of nipple clamps. The type that will pinch harder the more you pull on them. The idea was that as I move to the other end, the rubber band will pull harder and harder on the nipple clamps. Hopefully the following illustration will make it more clear what I mean:

I moved the ring with the clamps to the lowest position, and at the highest position I attached the keys to a pair of rigid handcuffs to the wall. The keys were on a string so that they could not be dropped out of reach later.

Then I went to the nipple clamps and started preparing myself. I was already locked in my "The Curve" chastity device, which I had been locked into for five days at that time. I locked a heavy chain around my waist and also ran some chain between my legs to ensure that the waist chain could not be pulled up. To the back of the waistchain I attached my rigid handcuffs. I then proceeded to lock steel manacles around my ancles, and then I locked the ancles together as tight as possible. This would ensure that I could only take very small steps, but just to be sure I added thumbcuffs on my big toes as well.

Satisfied with the feeling of being barely able to move at all, I locked a wide posture collar around my neck and attached the nipple clamps to my nipples. Already here at the lower end, I had to strecth the rubber band a little to make them reach my nipples, and I already felt a slight pain from the clamps pulling on my nipples. Then I put a blindfold over my eyes and after that, I put my hood on. The hood has holes for eyes, nose and mouth so I made sure to position it correctly so both my mouth and nose was free. After having locked the hood on, I attached the build-in blindfold on the hood. Everything was now completely dark for me. Finally I took my tongue gag and inserted it in my mouth through the mouthhole in the hood, and locked it in place. This gag is a thin, but wide and rather long leather tongue that goes into my mouth. It's comfortable to wear, and it is possible to breathe around it, in case the nose gets blocked for some reason. Still it fills the mouth good and makes it very difficult to speak, since it presses down on the tongue. Anyway... With all that in place there was only one thing left to do. I reached behind me and locked my hands in the cuffs, making sure the keyhole was facing in a direction so I could open the cuffs, once I had the key.

I was trapped now. There were only two ways to get free. One was to pull the nipple clamps off, but since they pinch harder the more you pull on them, this would be extremely painful, not to mention that it might hurt my nipples. The best way was to move very slowly backwards towards the key. This was made difficult for a number of reasons. First my ancles and toes were securely locked together. Secondly the further back I moved, the more the rubberband would tighten, pulling even harder on my nipples. Third, with the mask and blindfolds I couldn't see a thing, so just going straight and following the rope was actually very difficult. Well, I had no choice, so I started with very small steps to move backwards. Sometimes I could feel that I was going in the wrong direction by the increased pulling on my nipples, but that could also just be me getting closer to the key. With my hands locked behind me to the waist chain, I could not reach the clamps or even feel my way around the room. I had wandered around like this for about half an hour I guess and had no idea how close I were to the key. I was drooling from the gag and the pain on my nipples were quite intense, but it would take me another 15-20 minutes before I finally made it to the keys and could unlock the cuffs and remove the clamps.
