vac-u-lock system

The heart of the Doc Johnson's Vac-U-Lock modular sex toy system is the patented interlocking secure plug system that allows for the quick and easy interchangeability between many different Vac-U-Lock attachments.

The patented Vac-U-Lock plug is made of a premium quality, high impact ABS plastic and is designed to hold an amazing and varied range of Vac-U-Lock dildos, vibrating cocks, penis extensions and Vac-U-Lock accessories safely and securely to the Vac-U-Lock harness system.

Being a modular system means that you can start with a Vac-U-Lock harness, then add dildos, vibrating cocks, and penis extension attachments to your Vac-U-Lock system as your needs, experience and desires require.
