A beautiful device for a cock (best without the foreskin) and can be worn for a long time, but not secure. With some lubricant inside the tube the flacid penis can be forced backwards and out and the slave can masturbate. Easy after the ejaculation to force the penis back in. A good solution is first to pierce the cock head and then drill two small holes on each side of the plastic cage. A secure plastic locker can then - after the healing of the pierced cock head - be pulled straight through the cock head and the plastic cage and locked. It is then impossible to pull the penis back out and it is 100% secure. Some slaves can get an ejaculation even with a chastity device on, however there are no pleasures and, most important, no chance whatsoever of using the cock for penetration. A man with a chastity device will do anything to try to get out of it, so some creative thinking is necessary to keep him from masturbating.
