I am soon to be hosting a session with a self described "extreme pain whore". While I relish the challenge, as I have not had the pleasure of pushing a sub as far as she wants me to go, I find myself at a loss for ideas that are excrutiatingly painful but not injurious. Activities so far include whipping/striking/lashing the ass/breasts/pussy/thighs/back, dual fisting, painful position bondage, and large object insertion. That's what I have so far. Hot wax is appearantly a balm to her, and I have no electroshock equipment. I want this experience to be fulfilling to all involved, so if anyone out there has some creative and extremely painful suggestions, I would greatly appreciate it.
