The Vac-u-lock suction cup plug by Doc Johnson is a great little sex toy accessory to own. Already owning a couple of vac-u-lock compatible dildos at the time that I bought this, I was excited to see how well they would work together.
It arrived in a small square Doc Johnson box that fits in with the similar packaging of the dildos from the vac-u-lock range. Removed from the box, it is made of white rubber and is three and a half inches long. On first impression, it looks like something you would find in a hardware store.



Being made of rubber it is porous so can be hard to keep clean but seeing where it is placed during use, it's hard to imagine that it needs much cleaning but if it does anti-bacterial soap and warm water can be used.

The suction cup plug is very firm and easily pushed into the attaching dildos that it is designed for.Detaching the plug from the dildo afterwards is the hard part, this requires a little extra force but with with some turning movements while pulling slowly it can be achieved in no time. No need to worry about the two coming apart during use!

I have found the suction cup on this to be much better than expected. It can be attached to all sorts of surfaces,a few that have worked for me are, chairs, tables, tiled floors or walls, wooden flooring, smooth painted doors, oh and the bath tub has been one of the best places I've found to use this!
I have yet to find a smooth surface that it doesn't adhere to.



My favourite dildo to use this with is the Natural Thin Dong realistic dildo, Used together while straddling a chair is a mind blowing experience and, I can imagine, equally amazing to watch.

One more bonus I want to mention about this product is that it has made all of my Vac-U-Lock dildos now compatible with several of my O-ring harnesses, A nice affordable option until I can add a Vac-U-Lock harness to my collection.
