On all fours.

Most definitive my favorite site - my *********** on all fours head down in the pillow and her lovely bottom high up for any kind of naughty things.

I love to let her wait in that position to have her ponder the endless possibilities:

Inspection

Fingering

Taking her temperature rectally

Allowing her an orgasm with a powerful magic wand

Inserting a butt plug or other implement

Teasing her little princess with a feather

Inserting some of those mean suppositories

Putting some clamps or clothespins on her privates

Flogging her lovely bottom including her most sensitive parts

Applying the razor strap on that deserving behind

OMG one of his evil enemas administered with his syringe

Oh please NOT the cane

Can you think of others, my naughty ***********, can you?
