Her ambition is to get Sonoe to betray her husband and to start with the art of masochism and bondage, even if it is necessary to shell out money beyond seduction. However, her husband ends up suspecting his wife that in the course of time he ends up discovering something more than just a betrayal. ~~ Based on a story written by a master of SM, Dan Oniroku.
