Dressed in a full body rubber catsuit and gas mask, Hinako's sub is plugged up with a remote control anal vibrator.
He is first strapped into a canvas straitjacket and put through the wringer of harsh tease and denial.
He was starting to get horny, yet could ultimately find no sexual release as he was then zipped into a neoprene rest sack and strapped up tight by a series of belts, only to be left alone inside the PVC-coated white room!
Hinako had a bit of fun herself, as she left him in there for hours, occasionally flipping the wireless vibrator switch on and off.
