Need some ideas

[estimtom]

On Saturday I will be planning spreadeagle with estim2b power box connected to anal cock lock electrode, a plunging Pete urethra and penos head electrode and ball electrodes.
I will be tied onto bed wearing heels that are hard to walk in with legs and arms spread, when I am into the session
I push away the estim controls with a stick and throw the stick out of reach.
My release method is a very much tried and tested nuts on a long piece of all thread, so the plan is I cum but then have to undo a nut to be released, take a few mins while electro is giving me post orgasm torture.
I would like to add in something so when I am released and have turn the electro off, I still have a long wait or long walk to get fully released so hopefully I want to go through the process again and orgasm again, any ideas?
I would also like maybe some type of extra stimulation or pain.

Perhaps you could arrange a way in which reaching to turn off the e-stim necessarily pulls something covered in deep heating rub across your cock and/or balls?
