you know I am going to hurt you today, don't you, spew monkey?
Supposedly, it is to condition you to associate pain with spewing.
I honestly don't care about that, though.
Stop stroking.
Tie up your balls with a shoestring.
Make it as tight as you can stand.
Leave some bits dangling so that other shoestrings may be tied to them later.
When you are done, We will proceed.
