Sport Fucker has done it again. This is not merely a cockring. It’s a complete Boner Kit! The stretchable TPR allows both square rings to stretch over your junk and firmly hold it in place. Each kit comes with one square cockring with an attached ball stretcher plus an additional loose ball stretcher. Add one or more of our expansion packs and stretch those balls even further. No need to buy the same color, combine different colors for a great sporty look. Dare to free-ball in your jeans with our Boner Kit. The more ball spacers you add, the more friction and sensation you’ll be feeling. Add our expansion pack and throw on some raw-denim as you’re free balling. You’re sure to bust a nut just walking around your local bar from the friction alone!
