Fucking Machines

Every so often, someone brings up the concept of a fucking machine, a motor-driven device that shoves a dildo in and out of an orifice or provides another motion simulating fucking. You may have seen one in videos, although many that I've seen look like fakery to me. If you want tons of real videos of many different machine styles at work on beautiful women, check out CumBots or FuckingMachines.com. Jetaime (whose URL that I had died some time ago) and Sybian (www.sybian.com) both sell fucking machines, and now so do I through Orgasm Alley, where you'll find the largest selection of handcrafted machines anywhere.

Common Motions

There are several motions and stimulations that you might consider for a fucking machine. Jetaime and Sybian are a good starting place for two different approaches.

Jetaime is the better of the two, IMNSHO. Why? It actually fucks... that is, it has a dildo that goes in and out of an orifice. In the TFM pages, this is termed "thrusting." Jetaime also comes with a corded vibrating bullet that you're supposed to place strategically while in use. Here, they fall short of Sybian.

Sybian describes themselves as the ultimate (I disagree ;). Their machine "squirms" (my term)... a motor-driven, crooked shaft runs up the center of a firm-mounted dildo, causing it to bend and sway. They claim this feels like fucking, even though it's not. They also have a powerful vibrator mounted on the unit, transmitting vibrations straight to the clit area through a ridge in their special dildos.

So far, we have thrust, squirm, and vibrate. I'll add one more from my own TFM v4 - ThumpStir... thumping. As you'll see in the TFM v4 project, thumping is a rapid, short striking motion directed at the clit. Of all the motions, my tests show this to be the most intense.

Enclosures

There hasn't been much discussion in general about enclosure/case shape. Sybian and Jetaime are both "half-barrel" units... picture a barrel shape sawn lengthwise. An inventive acquaintance of mine uses mailboxes, which have a similar profile. All of these are meant to be sat upon.

TFM versions 1 and 2 are not. v1 (prototype) didn't even have a case. v2 is a small box. Both are purely thrust motion, and simply need to be set up so the dildo is at the right distance and heading in a good direction.

TFM versions 3 (planned once upon a time, but later rejected.. I've left the project here because it's neat) and 4 are sit-ons. While the shape of v3 hasn't been finalized, v4 is slightly modified from a pure barrel. Look at the pictures and diagrams on the v4 project page for more information. This shape seems more comfortable and natural.

The Versions

Here's the quick summary of the four different TFMs. If you plan to design your own (as opposed to using the v2 or v4 plans), I stongly suggest that you read all four sections. In each, I try to describe the hurdles I faced in construction, and compare performance of the various designs.

TFM v1 - Prototype

TFM v1

What does it do: thrust

Overview: I built this version to test the concept. It was screwed together from 2x4, 2x6, and angle brackets. Driven by a nice gear motor later salvaged for TFM v2, it used a flexible arm drive mechansim. Good motion, solid approach. I used it for a year before destroying it to make TFM v2. The flexible arm mechanism was replaced because it required too much length to work well.

TFM v2 - Fucker

TFM v2

What does it do: thrust

Overview: I subtitled this version "fucker" because I think it is the most effective pure-play design for thrust. It uses a gear motor, and pin-and-channel drive mechanism. This mechanism is more reliable and much more compact than the v1 flexible arm. v2 has a small, grey box containing the motor, drive, and height adjustment mechanism.

TFM v3 - Concept

What does it do: thrust, squirm, vibrate

Overview: v3 is slightly past the concept stage at this time, but the page here only describes it to concept. It is planned to be the "ultimate" fucking machine. Adjustable depth and variable speed thrust. Adjustable speed squirm. Vibrate. The natural drawback of all these things going on is that the mechanics will be (are already!) very complex.

TFM v4 - ThumpStir

TFM v4

What does it do: squirm, thump

Overview: If I were starting from scratch, this plan illustrates the approach I would use if I didn't mind a non-fucking motion. Unlike the previous three versions, which were almost entirely custom-built, v4 is two converted products in a box. Squirm is provided by a mechanism salvaged from a pasta machine. Thump comes from a very cheap version of the thumping back massagers. Variable speed squirm. Variable intensity thump.
