Secrets-------help
 

hey all
I am trying to track down information about a japanese movie called "secrets".

I am told that the story line is roughly this;

two friends want to loose their virginity so the answer an ad in the paper by a guy that is into bondage, one of the girls go through with it while the other does not. the girl that goes through with it, loves it and stays with the guy doing bondage all the time only breaking for food and buy new objects.

any help would be appreciated.
