Estim and sounding rod makes my cock twitch and cum

I've wrapped conductive tubing around the head of my cock and the estim pulse is making my groin twitch. Then I get the first sound pushed into my urethra and the fun really begins. Stroking the rod in and out, the current is connected from my balls through the middle of my dick to the tip. When my thighs start to tremble, I change to a larger sound and push it in and out slowly. The sensation builds to a wonderful strong orgasm and a flood of cum runs down my cock shaft.
