A curious solo explorer delves into the world of electro stim, setting up the machines and attaching the electrodes to his body. As the current flows, his body reacts, sending waves of pleasure coursing through him. His cock responds, leaking copious amounts of precum, glistening and tempting as it drips down his shaft. With a flick of a switch, he sets the machine to hands-free mode, letting the rhythmic pulsations bring him to the edge. His body tenses, and with a final surge of current, he's pushed over, his cock throbbing as it releases a thick, creamy load of cum.
