The "cubicle" was a u-shaped curtain rail in our old house's playroom. It was about 7 feet up the wall with two curtains on it. One black latex and the other semi-pink transparent plastic. It can be seen in two of images in one of my Zity albums...
On the wall below the rail was a padded bondage post, to which a sub could be cuffed to. Facing in or out.
I used it at a party we had once with a sub who loved to be touched. During the evening I attached her facing out, cuffed at writs, neck and ankle, so she could just move slightly. I then puled the plastic sheet around her. The beauty of this that anyone could make out her features but she couldn't tell who was on the other side. I'll leave it you your imagination, but she was there for a good half an hour and came 4 times.
Several women told me after that they loved the idea of touching her and her not knowing they had, and several had put their male sub in during the party.
