This type of bondage is not for the faint of heart and takes a real fetishist to be able to handle something like this. A set of handcuffs encasing the hands in steel is locked on to the wrists, followed by ankle cuffs and giant metal ball locked over his head, cutting him off completely from the outside world. Followed up by a spread-eagle position on the bed with more metal chains and some Hitachi, it got too crazy for this sub and he simply had to tap out. He’s just lucky enough Hinako let him.
