We got the Vac-u-lock plug to use with our new O ring harness and the Vac-u-lock dongs. Like other people we have problems with the harnesses when the dildo is not secure and stable, and this makes me feel like we have less control - a problem that is easily solved with a Vac-u-lock suction cup plug. This is one of the best ways to secure the Vac-u-lock dildo to an O ring harness. Besides the benefits of control and leverage the Vac-U-Lock Plug allows, it also adds to the authenticity of your fantasy or role playing by making the penis look like it's actually a part of your body.

The suction cup plug is also very good for bathtub and shower play. It worked great for attaching the Vac-U-Lock dong to our shower for hours of hands free fun. The suction cup plug can attach securely to smooth surfaces. Just because they are grippy materials and even while riding hard, the cup holds tight to the surface and has a little tab on the side for breaking the suction when it's time to clean up.

The suction cup plug will stick securely to almost any flat surface and stay there until you are done. The only complaint I have is that it's made of a relatively hard and slippery plastic and the suction cup can slide around, but without losing suction ever.

You can use the suction cup plug with all Doc Johnson Vac-U-Lock attachments and has a flat suction base for extra stability.

So if you're looking for a way to use your Vac-U-Lock dildos with your O ring harness, the suction cup plug will give you control and leverage. It is made out of firm rubber and has a flat suction base for extra stability during play time.

The suction cup plug is perfect for turning all your vac-u-lock dongs into an O Ring strap-on dong. Experience the fun and excitement as you take your erotic fantasies to a higher level.
