Why did not we think of this sooner? Such a simple idea cock ring with 2 ball rings connected by springy flexible silicone that tugs on your sack while you wank or f-ck. So stupid simple. Here is how this one works: 1. put your greasy cock and balls through the larger ring. 2. Flip up the smaller ring up under your balls, stretch it, and drop your balls through, flip the second ball ring up and drop your balls through that. Feel the tug! That is it. Jack-Off, f-ck some hole, stuff your dick in a hot drooling mouth.8-Ball will tug your sack with every thrust. The tug is not intense, it is just enough, keeps your balls down in their proper place and your sack gently stretched. We have tested this f-cker out on all kinds of meat: big hairy bull beef, piggy uncut pork, smooth tanned chicken tenders with shaved balls. They all dug it. It fits if you are hung huge or hunger, less huge with big balls or small balls. The skin flex silicone has enough stretch they all could wear it for a long haul. Even guys who did not use ball stretcher got off on 8 Ball. The ball ring is soft and flexes enough you do not get blue balls, but it does stay on even is you have a small sack. It stretches to fit a huge sack too. This one you can wear for hours and we do. It is the staff favorite.At Oxballs, most of us are simple single minded sex on the brain drooling dirty pigs, constantly groping our junk and making foul comments. That is just what we are. That is why sometimes simple is better. Features: Pure Platinum Cure Silicone. Lube safe: water base, oil base, water/silicone hybrid, silicone lubes.
