Ballstretching - m.holymoly.com

A scrotal ladder can be connected to a frenum ladder and even extended to create a guiche ladder as well! Also, the rings can pinch the skin, which is not only painful but can lead to injuries which then have a hard time healing unless the rings are removed.

The method is to wear as many rings as are comfortable, and gradually add one ring at a time.

In the extended state, what you do to stretch those tissues further is actually working on the tissues- like stretching a straight piece of wire.

The collar has a groove in the back which accepts the spring, and once in place the spring prevents the collar from stretching over the testicles again.

You may wish to go to a full cut rather than a standard cut in the same size to get some extra room in the crotch.

These can be found in most stores which sell bondage gear and in many catalogues.
