Does anyone have good suggestions on how to rig up a suction cup dildo to slide in-and-out so your hands can be free?

buy a fuck machine

I'm looking for other options since I'm married and being discret

I have an 8" suction-cup base dildo which I love to ride. I simply attach it to any flat surface (desk top, wall). I also have a hollow one which is a similar size. That gets attached to the end of a piece of pvc pipe (has to be secure so it doesn't come off), the rest of the pipe gets wedged and I either get on all fours, or I drape myself over an exercise ball and rock back and forth. Neither solution does the fucking motion for you but the feeling is still great. I have given some thought to making such a device tho. Maybe an electric drill strapped down set on a low speed, some kind of disk with an arm (think steam engine mechanism) which is attached to a point on the disk. As the disk rotates, the arm will have an "in and out motion". Haven't actually done it, but that's what I was thinking.

I built my own toy out of the handle of a garden shovel. I built in a hinge then extended the length so I can clamp it down to furniture. With this method I'm all fours riding it like a whore ha ha

Another method is to lie on my back while I fuck myself to my enjoyment, while holding the extension with one foot.

You'd really have to see it to understand it all. But I sure get my jollies off with it.

Maybe this would work:
