Positions for spanking (13)

Hung, or better, tied with the hands over the head (see safety) and as I like it, as high as to force the punished to stand on tiptoe is the traditional position for whipping on the back. The culprit can be bound to the ceiling or against a wall. Of course, it can also be used for hitting on the buttocks. The culprit can be tied with open or closed arms and the same with his/her legs. If you don't have where to tie the feet, use a separator bar. 

This one is not so easy, because you must have a post, or a column, but is interesting and traditional. The whipping post that could be found in all towns until the end of the 19 century was used for a thousand years to punish criminals. 

If you can play outside, you can use a tree instead of a column.

Be sure of being able to control where the whip's point hits. Learn over inanimate object, and practice. Don't hit the spine, neck or kidneys.

Another possibility with a column. This somehow offers the buttocks.

The elbows are bound one to the other, by the other side of the column, as are the knees.

And if you have a post or column, try this one. It is very sensual. As a man, and as a sadist, I can't avoid to imagine a woman shaking under the lash, with a post between her legs.
