Though I am standing on flat surface with nothing to cause me to fall over, when my arms are wrenched together behind my back, wrists tied, knees tied, ankles tied, and heels bound side-by-side, my entire body is completely immobilized so any slight movement can cause me to lose my balance and fall over. My constant fear of falling keeps me still and silent, I was scared out of my mind!. What a feeling! HD 720x480
