TruckT cockrings from Oxballs huge your meat with 2 different fits, the large one for a good grip on your cock and balls and good hard bone. The smaller one if you want more grip for rock-hard meat. Or wrap your cock and balls with the large ring and use the smaller ring stretched around ballsack for tons of grip. Made of super-strong Skinflex-TPR, the best material for strength and serious stretch. Stretched to 5 times it's size. Inside the ring is a shallow channel. As you stretch the ring this flattens out so the ring stays where you put it.
