Master Series Inertia Flexible Cum-Thru Plug

Urethral play gets a thoughtful upgrade with the Master Series Inertia Flexible Cum-Thru Plug. The hollow silicone shaft bends naturally with the body, making insertion more comfortable than a rigid alternative, while the stainless steel tip and interchangeable head rings add satisfying weight and a polished finish.

The cum-through design means you never have to remove the plug to reach climax – a feature that sets this piece apart for serious sensory play enthusiasts. Two ring sizes give you options: the large ring measures 1.2 inches in diameter and the small ring measures 1 inch in diameter, so you can find the fit that works for you.

Flexible design, interchangeable rings, cum-through access

The plug measures 4.2 inches in total length with 3.75 inches insertable and a slim 0.3 inch diameter – a reassuring starting point for those exploring urethral stimulation. The ring arm is 0.9 inches in length. Both the stainless steel components and the silicone shaft are hypoallergenic and allergy-safe, so the materials are as considerate as the design.
