My balls are stretched out a couple inches and a bi-polar electrode pad is pasted over each one. The estim current bounces back and forth from my dick to my prostate to my balls and back agin. My nipples are hooked up to a separate power box and is pulsing with a strong current. The pulse through my genitals is set on random, and some settings are a bit intense. My dick head is cinched so tightly, cum backs up into my balls. I manage to get it loosened and squeeze out some cum. So, hands free orgasm again.
