Sport Fucker Liquid Silicone Muscle Penis Ring red

The Muscle Ring by Sport Fucker is by far the most comfortable silicone cock ring on the market!
What makes the Sport Fucker Muscle Ring so comfortable ?

First, there's the design. Thick enough to rule out skin injuries, but not so wide and thick that it becomes too tight.
But even more important is a new silicone that was used to give the Muscle Ring a soft, velvety feel.
