At their joint request, and for a little variety, they had been placed in the triple kneeling cages that were joined at one end to form a three pointed star and they were enjoying the intimacy of this particularly special accommodation. The cages were designed to allow almost no movement by the occupants. Frank and Ellen had drawn up the designs after seeing some explicit drawings by a French erotic artist and had made their own modifications. The structures were built from chrome plated steel reinforcement bars and welded into a rectangular box shape with removable top and bottom. The sides were fixed and could not be adjusted, but the top and bottom could be removed or fitted and locked to compress the occupant. Additional steel bars were available to be inserted in the sides or from front to back to further restrict the movements of the occupant and once inside, the person in the container discovered that if properly set up, the box cage could restrict any movement whatsoever. This was the situation that all three young women now found themselves sharing.
