Gonna have to go with Fisting of any variety here (and the scatalogical stuff, but no point beating that dead horse). I'm at the office and Zoe is home, so (hopefully) she'll echo an agreement here.
Frankly, I'd be worried that it wouldn't snap back.

(Zoe had a c-section)
Even watching Bebe Neuwirth stuff her fist in her mouth on
Cheers was disturbing enough. She's sexy, but she ain't that sexy.
