My slave's balls are huge and there is not much skin between the pubic bone and the ball sack. for instance, I cannot even get enough skin to push the balls down into the sack to twist. he's been having a hard time with his CB 6000 because the ring pinches so much as he's not shaped so much like a funnel, but rather like a plastic bag. I've been considering ball stretching, to build more skin between the pubic bone and the sack. Has anyone had a similar issue making it nearly impossible to keep their chastity device due to the lack of skin area? Is there a better device than the CB6000? Like I said, the difficulty is not in the cage. We've tried the largest ring but he slips out of it.
