Before just throwing random tortures: the only thing we know is her name, has (dyed) red hair, wears glasses, and is 20 years of age, average figure. For the sake of the discussion let's assume she is russian. All together not so much to go by. Does she have any special characteristics that may help us decide?
Does the place of action pose limitations? I am afraid you will not have a large cathedral at your disposal, otherwise this would make a nice site for the following plot.
Keep her completely ignorant of all plans. Tell her nothing! Let the expectation grow and do its work.
Before the shoot, sedate her and plan your operations such that an hour or two before sunrise she is put up on a cross suspended from the height of the cathedral dome. Bind her to the cross, naked with just a loosely tied loincloth. Use no nails. If exposure of the privates is new or difficult for her, seize the opportunity and choose a crux position with knees parted, legs bent, sex crudely exposed if not for the loincloth. If she is all to used to it, choose a positon that is aesthetically pleasing. Give her a crown her with branches of holly, make sure the holly has the red berries in, so they can make a nice contrast with the hair and the leaves. In her butthole put a suppository on the basis of menthol in a wax coating for slowly release of the agent. Take off her glasses. Without that date repellent her eyesight will be slightly impaired which adds to the experience. For special effect, get hold a glasses-maker and while she is unconcious let him swap the lenses for a different strength. For ultimate confusion fit a system on the cross with small microphones and loudspeakers on the ends of the peribulum and let it distort the sounds she hears, something happening on her left she hears as on her right, etc.
Adjust height of cross to ensure she can look over all the obstacles on the floor and can be seen from all sides, but not so high that a spectator on the floor would have difficulties in viewing her details. Choose position, vertical or flight, to please the eye. An octangular pyramid stage from which she is on easy reach without disturbing the idea of being removed from the earth can come in handy, depending on plans for the last part of the session (see below). A top platform of one metre diameter with stairs flowing down in all directions will do. Eyelets to lash the cross when working on her are recommended.
When done, vacate the whole place. For your imags use remote operated cameras, disguised and hidden so she will not notice them and they will not be visible or easily ereased on the images made by other cameras. Make sure in the church all candles are burning and there is a distinct, but not too heavy smell of incense.
As she wakes from her slumber she will begin to realise she in in a place few have been before. Hanging still, she can look around only so far. Whatever is behind her she can not see. Her motions will set the cross with her on it to sway in a slow motion. The first moves will be irregular, but her jerking will reduce as she gets tired, the pain in her limbs sets in, and the sedation loses it's power. Then, she will note that moving only makes the pain worse, that crying in the empty cathedral makes no sense. She will stop moving, but the cross will keep swaying. Like Foucault's pendulum, the cross will turn a little with each sway, exposing her in all directions in turn. The early morning light trough the windows of the cupola will bathe her in soft light.
As the wax of the sup melts, the menthol will slowly be released and with the liquid wax be carried outwards and carried by sweat slowly spread over her tender parts. The loin cloth will help here. You may need to do some experimental work before to find the dose that will give sufficient irritation and eery feeling down there without causing injury. A second dose, inserted rectal or in the vaginal may be required. If you can find no suitable dose, try a 2-component solution, with two components that by themselves cause little or no effect, but are exellently effective when they come into contact. She can not investigate what is going on down there. She will only feel the effects, and the question what the f* is going on down there will add to her agony. She will try to keep the loin cloth in place (no avail, the cunning design makes it slip slowly), andonly after it is fallen she will notice it added to the irritation in her loins.
After sunrise, when she is sufficiently confused and dis-orienated. Enter and perform any ritual your perverted mind can dream of. Let the ritual be colorful, incomprehensable, and most of all let the ritual evolve around her without her understanding it. Let them sing and dance until the loincloth falls and make it an object of worship. Make sure those performing it do not pay any attention to what she is saying. Best use people who do not speak or understand her language.
From there work to a conclusion to your and her satisfaction.
regards,
B.
