have used duct tape to keep the good bits (pussy) spread open (in conjuction with clothes pins)...but locked away? yummmmmmmy
have heard of the zipper before but never tried...
and why didn't i read this before i bought clover clamps? darn it.
as a task, i recently used those minty breath strips on my pussy...laid end to end starting at clit and going to ass... OMG! a surreal feeling.
