Its awesome that your wife wants to play that game. It's a real thrill, isn't it?

Emily can really bite hard without leaving marks. But I noticed its not how hard she bites, but how long. If she keeps the pressure at the same spot for about 30 seconds, then it leaves a mark.

Emily has the preference of a knife I think. Because when she talks about removing it, she always talks about cutting. But during a 'bitesession' she does threaten to bite it off and sometimes bit so hard I thought she was going for it.
