Yank your crank with tingle-tastic e-stim for full weasel teasing that outshines any stroker you've tried before. Unlike vibrating sex toys which stimulate the surface of the skin, Jack Socket's electrical currents reach deep for total satisfaction. Based on TENs machine technology, ElectraStim products enable safe internal and external e-stim play for sensational pleasure inside and out. A far more effective way of stimulating nerve endings than any other method, the Jack Sprocket stroker is expertly designed to bring you to your knees with orgasmic satisfaction. A real-feel skin insert sits within a pliable silicone outer case, and is lined with dozens of pleasure nubs that caress your length just like an ordinary stroker. This feels amazing in itself but is even better when combined with a bi-polar electro-sex power unit for added zaps. For best use, remove both caps and connect your stroker to the power pack via the 2mm inputs at the base. Remove both gel port caps and apply plenty of conductor gel through these openings. Apply as much water-based lube to yourself and the toy as you desire and dive in! Now you're free to experiment freely with the various intensities and patterns that your ElectraStim power pack has to offer. Please note: Requires bi-polar electro-sex power unit with 2mm pins to operate (sold separately).
