oh, I've 3 favorites for different reasons...

My Sir's belt...its well worn and soft. I remove it from around his waist, so its warm, softer. This because he has instructed me to remove it from him and then hand it to him...I don't think that him pulling it out of the closed would be the same connection, but would indeed weild the same results...

His hands...simply the physical connection...

As far as instruments...I have a love/hate relationship with his cane...willow I believe...I love the delay in the pain from the moment it strikes me, and those seconds that pass....sigh...and then the lovely welts that it leaves for days and sometimes weeks
