Self-bondage Challenge
You do realize how screwed you are right now, don't you? For those who don't, let me explain. You've probably noticed that the clothespins don't hurt as much anymore, as they did when you first put them on. Actually, that is a very bad thing for you. You see, the clothespins are cutting of your circulation to the clamped flesh, causing it to become numb, which is why it doesn't hurt so much. However, once the clothespins are removed, blood will rush back in, and your flesh will be more sensitive than ever as it readjusts back to normal. It is sort of like you eyes squinting when you abruptly emerge from a dark room into bright sunlight. You are more sensitive to light when you have been deprived for a while. Except in this case, you won't be more sensitive to light, instead you will be more sensitive to pain.
Even if you had full use of your hands, you would find that starting to squeeze any of the clothespins open too quickly would result in a sharp pain, and you would learn very quickly to open them slowly. But you do not have the use of your hands, so opening them slowly is not an option for you. The only way for you to free yourself is to move towards your handcuff keys, which will cause the string to pull the clothespins off of you abruptly, which will hurt you far more then putting the clothespins on did.
Perhaps I should have explained this before having you lock your hands in? Perhaps, but that would have taken all the fun out of it, for me anyway.
If you don't believe me, then pull away until the first clothespin comes off of each of your thighs. Observe how much that hurts, and then think of how many more clothespins you have to go. And just think, of all the parts of your body that I had you attach clothespins to, your inner thighs are actually the least sensitive!
