I have that very same setup never seen it used. I have the butt plug for it shocks me good up in my ass. Put it on "pulse" and turn it all the way up. Bursts of electricty pounds my ass. I like to wear my sissy shorts and tape the controller right above my clitty and go to walmart and get banged in the ass. I use name tag clamps on my nipples with a quick open key ring and hang several big fishing weights on them. Those clamps have searated teeth and hurt pretty good by themselves but the weights really tug on the nipples and make them hurt worse. Every step is like jerking on them. I like it because it gets to be very painful and I can't take them off until I come back out.
I LOVE a long estim session where a guy plays with his electrodes, too bad I don't understand French, but I love the video and audio, and such a nice cock!
