Tear off a good size sheet of plastic wrap. An alternative would be to tear off a longer piece and wrap it between the legs and around the hips like a panty.
Step 2
Put lubricant on one side. Water- or oil-based lubes are okay for plastic wrap, but use water based lubes for latex barriers.
Step 3
Put the lubed side against the area to be licked. Be sure to keep the wrap from bunching up or turning over. Use a new sheet for each person. Go for it!
