I suggest you contact either Tima (in the Czech Republic) or Alexia Cage (in France). These women are vets of poop play and will answer any questions you have.
Tima is very sketchy with Engrish though so be gentle with her.
Tima's Website send me a pm if you want Alexia's contact info.

I hit her with the hammer on top of the head. She made a lot of noise and kept on making noise, so I hit her again.
