Hinako’s (by Japanese standards) 286lb (130kg) sub, dressed in his neck entry latex catsuit, wearing a PVC sensory deprivation mask, gets up on the gynecology chair and is tied to the chair with inflatable rubber and handcuffs and plastic wrap and then gets vibed by the vibrator!
Being as heavy as he is, Hinako was worried that he might break the chair when he sat on it, but it held out despite a little shifting!
