I have the most wonderful and incredible girlfriend who loves me so much. Those of you who have read my stories will have noticed the themes that run through them; that of huge cocks/dildos etc with the victims forced to experience multiple orgasms against their will during protracted fucking with them.
Given that these fantasies turn me on the idea of a fucking machine with a huge dildo figures strongly in my stories. Many fantasies have to remain just that but some we would love to do for real.
This one is a wonderful story and its all the better for being absolutely true. Since early on in our relationship we have shared our fantasies. My partner's stories have developed over time from what were almost exclusively lesbian content to a lot of incest/daddy sex fantasies.
Our fantasies are not an exact fit together. The idea of Daddy's fucking their daughters doesn't do anything for me in itself but I can go with it easily enough and merge her fantasies with those of my own. The story 'Martha's Ransom' was written with her in mind with several of her important themes incorporated.
Usually for her she is the seducing daughter rather than victim of rapacious father but she can go with that idea too.
So this is our actual real-life story. Throughout our relationship I have been obsessed with having her fucked by big things. Initially I bought a Doc Johnson dildo with vibrator which was large but not massive, about six inches around.
We then tried using bigger things, cucumbers and bottles etc. We had one exceptional time with an aubergine which she had the most intense orgasm on.
What we seemed to discover was that she can fairly easily accommodate something up to 7.5 inches in girth but anything wider than that would not fit. However, when I saw a Bam realistic dildo in our local sex shop about 18 months ago I just had to buy it in the vague hope that she might be able to 'work up to it' over time.
She did put it to her pussy but felt that it would be too large for her and it went in the drawer to gather dust. Last Christmas I bought her a more suitably sized dildo, a Ty Fox realistic which is dead on 7.5 inches around, right about her limit.
We have used this on many occasions although at times she has struggled to relax enough to take it.
During the spring I had some leave and decided to try to construct a fucking machine to fix the dildo onto. It was actually easier than I expected.
The mechanism to produce a thrusting motion is very simple. What I used was a 12volt windscreen wiper motor from a scrap yard which I bolted to a wooden bracket.
I bought a length of chrome plated steel tube (which was sold as a pack to make a bathroom towel rail). This came with two chrome plated steel holders which are designed to be screwed to the wall. These are basically short lengths of thicker diameter tube with holes drilled through them, through which the towel rail passes.
I screwed them to a 12 inch length of wood, passed the towel rail through them and greased it. They then act as bushes for the rail, allowing it to slide back and forth through them.
Using more wood I connected the bracket on which the motor is mounted to the one on which the rail is mounted. All that remained was to fix a short length of metal bracket to the spindle of the wiper motor. The length depends on the depth of stroke required.
I had used a bracket with holes drilled at approximately half inch intervals in case I needed to make it adjustable but I set it to give a maximum travel of 3.5 inches and that seems to be pretty much ideal. Any longer travel and it would fall out on the backstroke.
The rotation of the motor is translated into a back and forth movement via a length of metal bracket (all available from your local DIY shop). This is bolted to the end of the bracket that's fixed to the motor spindle and at the other end to a bolt through the towel rail.
I hammered a short length of metal with a thread on the end into the end of the rail so that I could screw something to the end of it that I could attach the dildo to.
Finally I bought some heavy duty two way toggle switches, wire and fuses and connected it all up to a 12 volt motorcycle battery. The whole mechanism I then fitted inside a wooden box which is about 14 inches long, 12 inches high and 8 inches wide. With some experimentation I also added a 4 foot length of wood which is detachable for storage.
This has the dual purpose of steadying the machine from moving about too much especially when it's used on a soft surface like the bed. It is also used as a spreader bar to hold her legs wide apart.
So there it is; a fucking machine for under £30. The way the motor is switched allows the two-way toggle switch to operate it in 'off'; 'slow' and 'fast' speeds. The speeds are not adjustable but in practise its 50 rpm slow and 100 rpm fast are really all you need.
I had built the machine without my girlfriend's knowledge but started telling her fantasies about them before showing it to her. She felt a bit self conscious about it but agreed to give it a go.
She first inserted the well lubricated dildo and then we attached it to the end of the rod. It is important to start with the rod at maximum extension, insert the dildo as far as comfortable so that the first stroke is a retraction. This ensures the penetration is not going to be too deep, particularly important if the 'victim' is tied down!
The initial trial was done at slow speed with a vibe on her clit till she came. The second time I asked if I could tie her down and video her getting fucked with it which she was happy to do.
I had her blindfolded, spread eagled to the bed with our bondage straps, and having got her worked up with my tongue, inserted the Ty Fox dildo into her freshly shaven pussy and attached it to the fucking machine.
I started videoing and switched the machine on, initially on 'slow' but after a couple of minutes to 'fast'. At that point she started moaning loudly with every thrust of that big rubber cock and even more so when I applied a vibe to her clit.
