If you’re ready to push your urethral play further, the Master Series Cadence Extreme vibrating urethral sound is built for exactly that. At 17.75 inches in total length with 14 inches insertable, this is a seriously long sound – and every centimetre is designed to deliver.
The flexible silicone shaft follows the natural curves of your anatomy with ease, transmitting vibration deep and evenly as it goes. A single one-touch button cycles through 3 speeds and 7 pulsing patterns, so you can dial in the exact sensation you want thrumming through your penis. The slim 5mm (0.20 inch) diameter makes it approachable for those building experience, while the length gives seasoned players plenty to explore.
Waterproof, powerful, and easy to control
The Cadence Extreme is waterproof, so clean-up is simple – just use mild soap and warm water. It’s phthalate-free and non-porous, though keep in mind it is not compatible with silicone lubricants. Use a water-based lube instead for the best experience. Power comes from 1 x AAA battery (not included), so you can be up and running quickly without waiting for a charge.
