When it comes (heh) to stimulation, you have lots of options. You can go classic with vibration or not-so-classic with electricity. Mystim's Twisting Tom is in the second category.
This silky, super-flexible silicone Prostate Plug is one piece of advanced-level sex tech you'll always want to have on hand - or in butt. Shape-wide, it's classic, featuring an angled tip and a broad, textured base that'll bump and grind on your outer butt and perineum/taint.
Function-wise, Tom delivers tingles and zaps of very stimulating electricity once hooked to a Mystim Electrostimulator power pack. There are four tiny openings at the bottom for connection with a Tension Lover or Cluster Buster controller (sold separately).
Twisting Tom's premium-grade silicone is non-porous, body-safe, and easy to clean and care for. You can add slipperiness with any water-based lube you love, but a conductive e-stim gel is your best bet when playing with electrostimulation. Twisting Tom is not for use in water.
