Instead a parrot perch not fully hanging but with back resting over a table could be sustainable for tighs or bottom whipping. Yup...imagine Amanda or Lyen in that position,
My new proposal is a hands tied high behind the back ( not so high as in picture it was just to watch an example of imho nice position ).
Absolutely safe letting the player enough room to kneeling on floor ( or over a bench before her ) in case of faint.
Suitable for back or bottom effective cruel whippping. Imagine Darcia or Linda in such position with their big boobs dangling under the strokes.
