Big Ox Cockring Oxballs Silicone TPR Blend. Whether you are looking for a beefier bulge for your jockstrap, a harder cock to stuff up a hungry hole, or you just like to wear a cock ring for the hot look and feel the Big Ox cock ring has got you covered. Big Ox is a thick, blubbery cock ring designed to grip your meat and give you even more girth. It is made from new Plus + Silicone so it has the strength and stretch of Thermoplastic Rubber TPR but the warmth and softness of smooth silicone. Best of all, the super soft material makes for a comfortable fit and feel for hours of play and stroking. The thick, fleshy design bloats your hog and rests snug behind your ball bag to push your hefty package up and out on display. If you are into ball stretching, Big Ox also doubles as a hefty ball ring for some stretch on your sack. Big Ox is so squishy and rubbery, it stretches to fit meat of all shapes and sizes.
