I've got balls!

Make no mistake, I'm all woman, but I got a package with a set of balls this week. Metal ones!

I had done the research carefully (best kind of research!)
I weighed (pun not intended) up all the options and sent Him a list with my final options.
He chose the one I'd secretly hoped He would.

And on Wednesday it arrived:
A set of metal ben wa balls. The kind that is connected with a string and had a handle.

Let's just say that I totally underestimated the power of having balls!

*blushes*
I can just about not control my body when they are inside. He loves them, of course.
He had me insert them, and clench down as it is pulled out (wicked!) And just kneeling with them just about sets me off.

Do you have any experiences to share with these little objects of torture and delight?
