Because the anus is a
very sensitive area, various types of torture or play can be done to
simulate, arouse or punish a slave without causing any long term harm.
This sort of play can range from very mild to quite extreme, so all Masters
or Mistresses are expected to start gently and respect the safe word at all
Play can involve sex toys such as dildo's or butt plugs, various forms of
dilators, TENS units for electrical play or (on the skin near the anus) the
use of needles.
