Source: SensualPain The Craniometer head cage is a very painful restraint that is used in extreme scenes. I thought it important to document and publish the initial fitting to the head of slave Abigail Dupree. It has many moving parts that require adjustment to fit any size cranium for extreme torture or sating the head bondage fetish of the masochist. Putting the screws to her is not the intent here, but to show the fitting of this unique medical cranium measuring instrument re-engineered, re purposed for the intent of restraining the cranium for B&D bondage and discipline.
