I have always been a great believer in the idea of 'the punishment fitting the crime' so when I discovered that my girlfriend was cheating on me it did not take long before I had decided what to do.
For several years I had toyed with the idea of creating a fucking machine, some means of making a dildo thrust back and forth as a novelty/ pleasure device but never thought my girlfriend would want me to try it out with her.
So it remained just an idea, albeit one where over the course of several years I had collected bits and pieces with the vague plan of constructing it one day. I had a small gearbox and small but quite powerful electric motors from my modelling attempts and had bought a steel rod which had two holders for it that could be used as bushes to allow the rod to slide back and forth in.
I also had a windscreen wiper motor in the garage that had been there for years and it was this that I eventually pressed into service as the motor for my mechanical dildo.
Having discovered Marie had been seeing this other guy I decided I was going to leave her and wanted to see her suffer in the most fitting way I could imagine; if she wanted more cock than I was providing I was going to give her more…a lot more!
Unbeknown to her I took a weeks vacation and spent it at home constructing the fucking machine while she was at her office.
On Friday it was ready for action, right on schedule, the mechanism set in a wooden box about 14 inches by twelve by eight, complete with a eight inch long but enormously thick rubber dildo fitted to the steel rod. The dildo I had purchased especially for the occasion. It was extremely life-like but terrifyingly thick for most women, exactly what I wanted! I was rightly proud of myself as I gave it several trial runs and it worked perfectly, the massively thick rubber cock thrusting back and forth in a very realistic fucking motion. I had even added a thin tube set inside the dildo to pump lubricant into her as it fucked her.
At seven p.m. she phoned to say she had to work late and I knew she was meeting up with her lover. No matter, it gave me plenty of time to pull out the straps we had used in the past for bondage games and attach them to our bed.
When she eventually arrived home at 10pm I acted all sympathetic, saying they take advantage of her at her office and pouring her a large Jack Daniels, laced with 10mg of Relanium. Within half an hour she was as drunk as a skunk and I took her to the bedroom, undressed her and had her strapped to the bed before she really knew what was going on.
I couldn't help noticing how gorgeous she looked. She had evidently lost some weight and stretched out like this it really accentuated her slimness.
She didn't even seem to register what was going on when I pulled out the huge cock and showed it to her.
"What the fuck is that?" she giggled sleepily. "I hope you don't think that's going in me…its fucking huge!"
"That's exactly where it's going Marie, right up your greedy little cunt!" I snarled. "I know all about you and Mike you little whore…Well if you wanted more cock you should have asked" I pressed the huge bulbous head of it to her slimy wet slit… She had obviously been fucked already.
"Now you're going to get more than you bargained for…lots more!" and pushed it hard into her cunt. At first the huge rounded head went in without much difficulty but as I felt resistance she gave a low moan. "Aaaagh, noo…God that's too big, you're hurting me!" she cried as it wedged in there, the thick rubber shaft bending under the pressure.
"Shut your mouth and open your fucking cunt you silly little bitch…you are taking this cock whether you like it or not!" I yelled as I began pumping it into her, each thrust of the massive tool making her cry out in pain as it advanced, slowly taking possession of her as it inched inside, torturing her with its blunt headed thickness.
"Oh God, please take it out!" she cried "I'm sorry about Mike, we didn't mean to…AAAaaaaghh! Oh God, no, please!" she cried as I watched the whole thing disappear up inside her dreadfully dilated pussy and she writhed about in discomfort. To be honest I was surprised how easily she had taken it, no doubt the diazepam and vodka had helped relax her….God she did look sexy like that…all eight inches of it buried to the balls inside her! Stretched out as she was I could see the muscles in her belly spasming involuntarily as she groaned loudly, her body's futile attempt to reject the bulky intruder.
"Please" she whimpered "Take it out, it's hurting me…"
"That's the idea you little slut, it's called revenge…and I've only just started; now you are going to get fucked by it and believe me its going to be the fucking of your life!" I taunted her.
