This chastity device can serve a couple of purposes depending upon how much discipline you want to inflict. You can use this as a very effective chastity device. Place it around the shaft of his penis, then when he gets an erection the points will dig into his most sensitive flesh. If you want this to be very intense use the smaller 1.5 diameter size. You can also make it into a spiked cock ring. To do so place it at the base of the cock and balls and lock it on with a padlock. Or you could make it into an interesting ball stretcher device by wrapping it around the scrotum of the testicles.
Specifications: A 4-row Sexy Sadist means that the ring has four rows of stainless steel teeth. Each tooth protrudes 1/4" from the steel. These are not self-locking rings. You'll need a small padlock to close them.Sizing
There are two sizes available: 1.5" inside diameter and 1.75" inside diameter.
: To ensure proper fit, measure the width of your cock (take that measure at the base). That's your diameter. This way, you'll know which of these sizes will provide the better fit and most comfort.
