The concept: With a standard Fuck Machine the dildo travels in a straight line, my thought is if you put it on a pivot, the path would be an arc. My favorite position is lying on my back and as pleasurable as it is, I kept wondering, what if the dildo had a bit of an upward angle so it would have more contact with my prostate?

Sure, I can set up the Fuck Machine in another position such as doggie style to achieve that, but I prefer lying on my bed with full access to my cock.

This idea has been in the back of my mind for a while now, well I finally got the vision on how to execute it and I worked up some plans. Most of my ideas start out as rough doodles and if they have merit, I’ll refine the plans further.

I designed it to be a stand of sorts that I mount my Fuck Machine to providing the stroke action. The stroke of the Fuck Machine is set to 3 inches, however because the dildo is mounted further away from the pivot point, it has a stroke of over 4 inches.

That idea expanded to possibly include another arm coming off the pivot that would stimulate my cock at the same time. Simulating a chain gang experience. However, I decided to focus on getting the dildo action working first and add that feature as an attachment in the near future.

As I’m building something like this, I try to stay flexible with my plans. As the project starts to take shape, I often come up with more reasonable construction solutions while keeping an eye on the critical parameters.

Within a few hours, I had a working prototype, and the idea of what I was going to do with it was really making me horny! I had to try it out and it didn’t disappoint! I need to do some refinements to it and I’m looking forward to developing attachments for it.

The Cock Stroking Attachment

It took some effort, alot of measuring, fitting, adjusting and tweaking, but I finally got this to work. I now have a machine that will fuck me and jack my cock at the same time!

I have to be honest, I was really unsure if I could make this work. But when I first proved to myself that it would, I laughed my ass off! It is such a crazy idea and it works!

It’s kinda cool how it worked out, as the dildo is penetrating you, your cock is penetrating the sleeve. It’s a wild sensation, it’s almost too much stimulation, your mind is not sure what to concentrate on.

Figuring out the sleeve holder was tricky, I wanted to be able to get into position, slip a sleeve on to my cock and then attach to the machine. I ended up combining a spring clip with a pvc pipe connector that I had cut into two halves.

I also figured out a way to hold the mechanism up out of the way while you get yourself into position. You can pull the pivot pin and use it in another hole half way down the arm.

The two uprights that the cock stroker pivots on where the first things I attached to the machine. And I found that they make a great handle for using the fuck machine aspect, so they will be on there permently whether I’m using the cock stroker or not.

Double Action Ver.1.2

I redesigned the cock stroking attachment, the first version worked but there wasn’t any way to adjust the positioning. With this new design I’ve added three points of adjustment.

Height Adjustment: The swing arm now can be moved up or down to set the height of the sleeve carrier. To adjust it, I pull out the pin connecting the swing arm to the tower and choose from four different positions giving me about 2 inches of adjustment.

Fore & Aft Adjustment: I replaced the push arm with a turnbuckle, this allows me to adjust the position of the sleeve carrier towards me or away. It has about 2 inches of variance.

Sleeve Angle Adjustment: The sleeve carrier is now on a swivel so I can adjust the angle of the sleeve. Once I have it at the angle I want, I lock it in place with a wing nut. I tried using it with the wing nut loose, but that lessened the amount of stroke.

I’ve also added a new foot to the front of the machine to keep it from sinking into the mattress.

These updates are a great improvement and make the machine more compatible for different body types.

This toy has gone beyond what I thought I could do. Here’s a video of it so you can see the double action in motion.

You have no idea what it’s like to have this sitting between your legs, however I do, and all I have left to say is: WOW!
