Various other devices are available for ball stretching, either
as serious stretching implements or as erotic enhancements.
They generally have the same requirements and restrictions
as other forms.

The picture above shows a 'Ball Tamer' which is a very heavy
2.5 lbs. Great fun and hugely erotic, and also good for very
quickly maximising whatever stretch the wearer has. Of course
at 2.5 lbs and being bulky, it is not an all day proposition, so
is limited to home indoor use for peroids of hours not days..
..........unless you know different!

Bull's balls are a leather sac filled with lead shot and the
same applies with regards wearability to the above.
