Invader might be the middle-sized butt plug in the ElectraStim Extreme range but there's nothing middle-of-the-road about it! The Invader Extreme Electro Butt Plug has an insertable length of 4.7 inches with an impressive 7.4-inch girth that will leave you feeling filled to the brim. Middle-sized plug from the Extreme range- designed for advanced players graduating from the Intruder. Bipolar construction. Weighty aluminium with rubber rings at the base- so you can comfortably hold it during use. The incredibly heavy metal electro butt plug offers intense pressure for firm stimulation of the prostate or against the vaginal wall. Only advanced anal sex toy users should take on the Invader bi-polar butt plug challenge due to its huge proportions. You'll feel sensation over a big surface area with this metal electro butt plug, creating intensely pleasurable contractions in your ass and pelvic floor when plugged into any of our ElectraStim stimulators. Make sure you have a big bottle of water-based lubricant on standby, this giant anal probe needs plenty to assist insertion. Please note that in order to experience the full power of larger metal electrodes you will need to use our AXIS, Flux or SensaVox stimulators.
