BIG OX is a blubbery. thick cockring made from our brand new PLUS SILICONE. which combines the strength and stretch of TPR with the warmth and softness of smooth silicone. The padded design rests behind your sack and pushes your package up and away from your body for a bigger bulge. The soft. fleshy material and squishy design are built for comfortable wear and use. BIG OX also doubles as a hefty stackable ballstretcher.
