As an extra spice to your sex life why not try the Fetish Fantasy Shock Therapy Electro Nipple Clamps, which both squeeze on the nipples and send small, arousing electrical impulses.
After you attach the clamps to your nipples, connect the remote control to the wires so that you can adjust the intensity of the electrical impulses by turning the button from "slow" to "fast", depending on how much “torment” your partner can take.
The remote control can also be used to give electrical impulses to other parts of the body. Set the remote control to "IN", put the metal part with the ball against the area you want to stimulate and turn up the impulses and feel the titillating and prickling sensation.
The nipple clamps are made from plastic and therefore easy to rinse clean with warm water and wipe with sex toy cleaner. The remote control isn't waterproof but can be wiped with a damp cloth.
When you play with electro stimulation it is always a good idea to read the user guide thoroughly before use.
