Bound in a homemade bondage box of his own design, this inventor got more than he bargained for when he was to wear a gas mask and inhale Lady Hinako's piss. But things escalated even more when a enema was dealt upon him. His ass exploded into the diaper he was wearing and it was quite embarrassing for him. He would not go without vengeance though, because with the help of Mistress Chiaki and Mistress Yaya, he was able to get his revenge on Lady Hinako by putting her in the box and giving HER an enema. They also used a Hitachi to make her cum a bunch of times.
