This is the story of Lulu and her thrilling embrace of the knots and cords which bind her.
From the moment when she hurries into the chamber where the instruments await her we see Lulu made more and more helpless.
Shadowy figures criss-cross her excited breasts with painstakingly elaborate knots.
Then adding remorselessly to her predicament her legs are bound apart. She is held dangling in her dream of total submission.
There is nothing she can do except to be overwhelmed until she is brought to the surprise ending and the climax of her experience.
