In a special collaboration with Hinako Bondage Clinic and Tokyo Bondage Laboratory, Chiaki attempts an extreme bondage challenge. Hinako, dressed her shiny Leohex leotard and long leather boots, gets tied in an inflatable rubber jacket. But that's not all! Cuffs are then attached to her legs and she is hoisted upside down and to top it all off, she is tape gagged. But you all know Chiaki; she just can't leave well enough alone and she just has to bust out the vibrator, too!
