Jock Lock is a great updated version of the traditional Ass locks. This 100% Premium Silicone asslock will stretch over 200% its original size and has a nice 45 mm (1-3/4”) Ball Plug on the end that will keep your ass in check. The attached cockring is 50 mm (1-7/8”) so it’s not too tight and not too loose. The 10 mm (3/8") neck on the butt plug means you can wear this asslock all day long with ease. 100% Pure Platinum Silicone.
