Electrical play (E-stim)

Using devices that send electrical current through the body for a buzzing, shocking sensation. This includes violet wands (which zap the surface with visible sparks) and TENS units or more hardcore stun guns/cattle prods (not recommended outside advanced scenarios). Done right, e-stim can produce anything from a mild tingle to muscle contractions to forced orgasms (there are conductive loops for genitals). You must avoid the chest (to prevent interfering with heart) and head. Stick to limbs and genitals. Start very low because even low voltage can feel strong. There’s specialized gear for erotic e-stim which is safer than improvised stuff.
