I have a very simple-- yet very devious-- CBT assignment for you. You are going to find or create a leash for your cock. You're going to tie it just like I instruct, and then you're going to have to use it to torment that cock while you stroke. I'll even tease you a bit to make it fun, but don't think for a moment that this will be easy.

Just imagine me yanking you along.. leading you by only that bit between your legs..
