FUUUUUUUUU** (so that's how bull semen is collected) wow doesn't cut it as a superlative magnifier, blasphemic screaming neither, every orgasm I had hurt more than the last in that way that feels soooo good, just don't do it dry get the conductive blue gel in bulk too

The bigger of the two rings is large enough to go around both cock and balls, with the smaller one sitting on the shaft. Connecting the output of one channel to one terminal of the large ring, and one terminal of the smaller ring, with the output of the other channel to the other two terminals, gives a nice shock distribution. Intensity can be adjusted all the way from 'nice' to 'scream'. I'm going to have great fun with these items.

The inner surfaces of the rings are made from conducting plastic material (electrodes). With my 'erostek232' signal generator the sensations were first class so I rate this product as a very good investment.
