Dull the edges of 5 ice cubes (rub them dull with your fingers for safety) and place them in your pussy (cracking open the wax seal if you need to
). Keep the ice (water as it will become I assume quite quickly) in there for the next 3 tasks you do (unless another person's task grants you earlier relief). To fill out the time slot restrain yourself as best you can and spend 10 minutes with your Hitachi wand suspended above your pussy so that it barely makes contact. (I believe an older thread on here called it the hanging vibe
)
