The sub will wear a pair of cuffs that once activated, will attach together prevent use of their hands. The dom can activate or deactivate them at any time, including in public scenes. Once activated, the subs hands will be pulled and locked together. Fighting and trying to get free only causes them to tighten. They will only unlock once the Dom deactivates them. The sub's hands can be pulled either behind their back or above their head if there is something else to attach to. If the cuffs lock to something about the sub's head, they can't move away from where they are, but can still move if they are locked behind their back. The sub is unable to remove the cuffs once they are on, as the Dom is the only one who can take them off.
