Enjoy this affordable hand crafted chasitiy device by yourself, with somebody or use in training on your sub. The 1/4 # weight of the device will hang nicely on you or the person you choose to use it on.

The hollow insert can be adjusted with a set screw on top to shallow or full depth insertion, 2.2".  Add an alligator clip and a lead wire from your power box and the hollow insert will "cum" in handy as you observe the man juices flow from the excitement.   If you are not into the sensation of spikes, simply use a piece of our 3/4" wide conductive silicone as a buffer.  :)  For non-electrified use, just use any wide rubber product to reduce the affect of the spikes.  Used as a single-pole electrode will require a second electrode placed somewhere else of your choosing in order to complete the circuity.
