What is a Vac-U-Lock Dildo?

A Vac-U-Lock dildo is a sex toy attachment system that allows users to attach a suction cup onto the Vac-U-Lock dildo of their choice. This system, invented by Doc Johnson, allows the sex toy to stay in place during any sexual activity.

The idea is simple. Vac-U-Lock compatible dildos have a hole in the bottom. Doc Johnson's system consists of two parts: a Vac-U-lock plug and an adapter. Combined, these parts create a vacuum within the dildo, maintaining its stability when you're going hard.

Fit for those who are looking for that extra spice in their sex life, Doc Johnson's attachment system is perfect. All you need to do is insert the Vac-U-Lock into the dildo, and you're ready for a wild ride!

No matter how hard you go, Doc Johnson's Vac-U-lock attachments will never let the dildo fall. It doesn't matter if your sex sessions last for minutes or hours. The Vac-U-Lock system will always stay on.

Dive into your fantasies without worrying about any equipment mishap ruining the moment. Focus only on your pleasure.

How It Works: Doc Johnson Vac-U-Lock Attachments and Dildos

To get the most out of Doc Johnson's Vac-U-lock attachments, it's important to know how to use them safely.

The Vac-U-Lock hole is tight and it consists of a small ball with adapter. To attach the sex toy, it's recommended to use a bit of baby powder. Hold the Vac-U-Lock dildo sideways and bring it closer to the plug. Start twisting it slowly until the adapter is fully inside.

Once you have mounted the sex toy, apply a water based lube on the toy and your body. You can use your sex toy as a classic dong, a double penetrator, or as an attachment on your sex machine for strap on sex.
