Look at what we have here! It’s another devious CBT task. You’re going to need a string and some clothespins for this one. You’re going to make yourself what’s know as a zipper. You’re going to string together a set of clothespins and attach them to your very sensitive balls. I will allow you to stroke only after you’re all pinched up. Then, at my command, you’re going to rip all of the clothespins off all at once.

It’s not my job to be nice to your balls. It’s my job to hurt them.
