There are plenty of ways a dominatrix can inflict pain on a submissive male. One of my least favorites is electric play or electrical play. What I often refer to as shock a cock.
Not all electric play involves pain.

You have to love perverts!
The sensations the toys provide can range from a light tingle to an intense shock.
If you decide to try electric play, make sure you read and understand all warnings and directions. You don’t want you or a partner to get hurt.
My entry into electric play started with a TENS unit I had purchased to massage my lower back. I decided, out of curiosity, to try placing the pads around my groin and on my penis.
Apparently I’m a pervert too.
Fast forward to a few years later when my Goddesses sent me to find some new toys for our videos. There in the sex shop was a Tens Unit with cock bands. Remembering the pleasurable vibrations, I added that to my cart.
I can’t remember the first time we actually used electric play in a clip, but I can remember one of the worst. We recorded it in the clip: Guess The Grunt.
Goddess Nyssa had invited Goddess Savannah over to play with me. Nyssa had never used the TENS unit on me, but since Savannah showed interest, they pulled it out.
Remember above I mentioned to understand all warnings and directions? Well, that is if you don’t want anyone to get hurt. They had no idea how the thing worked. Since both electrodes would be on my penis, no electric would flow near my heart. So they figured everything was fine.
When the low settings illicited no reactions, they jumped straight to the high ones. My reactions drew big laughs from both of them as they experimented with each button.
The downside on video is that you can’t see or feel the shock. All you can do is witness the results. Believe me though, the results are very real. I am not that good an actor.
At the end of Guess The Grunt, Goddess Nyssa took the necklace holding my keys and placed it around the neck of Goddess Savannah. And ever since, electric play has been one of Savannah’s favorite ways to torture my penis.
