E-stim can feel like all sorts of things, it depends how you connect it to your body and where and what sort of controller you have and what settings you use. As an example, I use a basic TENS machine and put one loop around my balls and one into my butt. On setting #4 it feels like someone is yanking on my balls at the same time there is electricity buzzing through them and all the way to my asshole. It's intense. If you want to know more, PM me.
Wish I were closer. Love being restrained-usually spread eagle, although would try this one, body sweating, muscles straining, cock hard as a rock and the electro turned up until your shooting multiple orgasms. Only thing better would be to add intense nipple clamps-makes my cock even harder.
Super !!! At 6.40, I came. I like to play like that too. But the second elctrode I insert with the plug in my ass, right on my prostate. It feels so much better that way. Try it.
