The Oxballs Thruster in Black is the perfect cockring for men who want an enhanced erection, but also want more bulk and a great look under clothes.
 
This black cockring is designed for comfort. It won’t pinch and can be worn on the base of the penis, or under the balls to give them an upward lift for extra bulk. This penis ring is made from non-toxic, phthalate free FLEX-TPR. It adds bulk under your gym shorts or your work trousers, making it perfect for wearing out and about, too. This accessory has a flexible, squishy design. It feels incredible on your skin, and can be used with a water based lubricant for enhanced pleasure.
