COCK - LOCK is a rubbery chastity cage that doesn???t require any locks, parts, or rigid materials. It???s made from our SuperFLEX tpr making it the softest cock - cage out there. The blubbery design and soft material double as a packer to beef up your bulge and fill out a jockstrap or y our favourite tight gear. The built - in COCKSLING at the base grips your shaft and balls and keeps COCK - LOCK snugly in place.
