Estim, orgasme mains libres avec des couilles attachées

My balls and dick are bound with silicone bands. Electrodes are attached to my nuts, with each ball getting its own estim channel. The electrode stuck on my cock makes it twitch as precum dribbles out. My balls start to swell from the constriction and the estim pulse. Then I turn up the power and twitch my dick into a hands free orgasm.
