Shape-wise, this slick, bumpily beaded aluminum penetrator features a smaller swell up top and two wider ones below. You can tug and twist the base for a custom inner massage or go hands-off and let your body - or a partner - take control.

Function-wise, Boris delivers tingles and zaps of VERY stimulating electricity once hooked to a Mystim Electrostimulator power pack. There's a cord at the base that you'll plug into the Tension Lover or Cluster Buster controller (sold separately).

Bold Boris's aluminum surface is non-porous, body-safe, and easy to clean and care for. You can use it with all lubricant types, but if you're playing with the electro function, choose a favorite water-based lube or conductive e-stim gel.
