X marks the spot

I have an image in my mind... a large room, high ceiling, an X marking the center of the floor, and you being ordered to take your position there, standing there, nude, waiting...

Her: Whimper

Cuffs fastened to wrist and ankles, spreader bar attached to your ankles, rope lowered from the ceiling and attached to your wrist, before it is pulled up, leaving you standing there, nude, thighs spread, arms over your head, vulnerable, and waiting

Her: Please!
