Thanks for the idea Jethro.
I thought you were gonna post a thread about getting pets to do stuff instead of... well, never mind.
From my experience, balls are sensitive enough to be awesome regardless of who licks them - or every single ladies who've licked Smokin' Aces are really good. Yes, I've named my balls Smokin' Aces.
When you are fresh out of shower (i.e., when you shower at the location), some ladies will be brave enough to venture into taint as well.
You know what else is good? Have you ever had a lady beat box on your balls?
