Balls have long been overlooked as a stimulable sexual organ - the Balldo changes that forever. 

By wearing a Balldo, users are perfectly encapsulated in the soft skin-safe silicone cage behind the penis-like conical tip, ready for ease of penetration. When inserted into a partner, the sensation is out of this world - for all involved. 

Not only does the Balldo get testicles inside a partner, it also allows users to thrust, almost identically to with a penis. However, unlike a strap-on, the wearer gets stimulated through the thousands of nerve endings within their testicles and can actually have a ball orgasm - or ballgasm for short.

The Balldo is made rigid enough for penetration by its patented inner core and by adding one or two of the provided Balldo spacer rings, with an upper ring stretchy enough for Balldo to slip on as easily as putting on underwear. These rings can be added or removed depending on how much loose skin there is above the testicular sac. If the wearer is particularly loose, extra spacer rings can be bought to compensate. 

Balldo gives users a second penis that never goes soft so the pleasure is virtually endless, allowing both parties to reach an intense climax. For those who are smaller in size, or that suffer from erectile dysfunction or premature ejaculation, the Balldo offers a second chance to please and be pleased, without the worry of going or being soft.
