Plus ça tremble, plus ça fait mal. Estim, orgasme mains libres.

With my dick and balls connected to an estim box, the electric pulse feels like my groin is being whipped... my cock twitches in time with the pulse. The more I turn up the pulse strength, the harder my dick twitches. The pain and pleasure mix together as I switch among the estim pulse patterns. I edge myself as long as I can until I orgasm while my whole body spasms.
