Fucking Machine Fantasies

This is where you can share your fantasies about being machine fucked or doing it to others. Maybe they can become reality. You can post your fantasies in the comment field below or send them via the contact link and I’ll publish them annonymously. Be sure to let me know if you want to be anonymous or if you want a signature or contact information.

There is a very strange problem that can occur with “profane” text. I have the allowance set at the highest level to allow as much fucking profanity as possible and most stuff gets through but there seems to be some limit. I can not figure out what puts a comment over the line. It seems to be a content analysis with frequency of “profane” works and how they cluster. If you try to post and get a 403 error. Try lowering the fucking density of your fucking profanity. There is no limit here, I can write about getting your ass double fucked  by two fucking machines while sucking a huge cock and but it might not pass in a comment. If you just can’t get your fucking comment to go through, sent it to me via the contact link and i can post it here.

Here is my favorite fantasy to start:

So far, I have only built two, but my machines can be “slaved” to all work from one controller. My dream is to have 10 to 20 fucking machines with an equal number of hot assed eager studs all needing to be fucked silly. All will be linked up or in a circle and I will control the machines. I was never much for team sports but I am willing to be the coach for this one. I will start out slowly and to the accompaniment of pounding music will simulfuck all until they scream from the joy of having the best asshole fuckings of their lives.

    I have lots of fantasies with this machine. The first fantasy would be to experience a fuck machine! I have been wanting to experience one for a long time and this one looks AMAZING! I’ve also heard it feels AMAZING as well. The next fantasy I would love to experience changes the whole cyber sex thing. I would really find it hot to have a fucking machine set up with a remote control that could be connected using an internet connection. The bottom of course would position itself in front of the machine and they could get on a webcam and let their partner control the machine anytime. It would give the possibility to feel like your partner is fucking you even when they don’t have the option to be with you for the moment. Personally I have a partner that lives in a different county. It would be awesome to feel the connection that he is fucking me and plowing my ass even though he lives a few thousand miles away.

    Thanks for the fantasies. I am actually working on a remote control system that would allow control over the internet or possibly even a phone connection. This is quite a challenge but I hope to have it working soon. If this works, it will be possible to have a machine on either end of the line and have both synchronized or to have just one machine and only a control on the other end.

      Hello,
      Brand new here!
      I would like to test it!
      Have you a system set?
      If not , let’s create it

      They will cum. In SOCIAL DISTANCING MODE$$$$

    Mmmmm….so sexual! My fantasy might include the use of suspension and a sling. Very comfortable and using lots of lube. Using the great 3 knob controller and either a machine operator or a preprogrammed SD, very slow penetration. Tap tap taping ever so slightly on the prostate producing precum and an erection. Perhaps even slowing to a stop in mid penetration and if allowed under the rules of engagement…..taking a dose of poppers or taking a small token of 420….. letting the Fmachine re-engage ever so slowly for a two hour eye crossing sexual encounter.

  4. Karl says:

    Your machine is a fantastic piece of engineering done right. I love the idea of pre-recorded programs that can be edited copy-and-paste-style.
    Just combine that with this little idea: Make a device that records movement through an accelerometer. Ask a porn company of your liking to have the tops wearing said decices in a location where they can faithfully record thrust movements, and then supply those recordings as downloads from their website when you purchase their videos? How about videos filmed POV-style, for instance – from the perspective of the receiver?

    Here’s another idea: A wrist-worn accelerometer for using when wanking, mimicking the wanking strokes through the actuator! 🙂

    Anyways – really hope to see this developed into a product for purchase and/or diy with kits to order.

    I would really like to know,one what it would feel like to try it,and two,my wife has a girlfriend.. I would love to watch them on it and they want to watch me. How can I get one pleeeeeez!!!

  6. Dildofunboy says:

    Would like to be restrained have a web video camera directly on me. A fucking machine with the HUGE twelve inch ” HUNG” vacu-lock dildo from Doc Johnson attached to the machine.

    Would get into having straight or bi-sexual guys log into a site where they could control the machine and how hard and deep I get fucked.

    I have many many machine fantasies I would love to try…

  7. justafreeak says:

    the idea of having a machine fuck me for hours really excites me.. I would love to be fucked until I cum over and over again.. I would love to be tied up in front of a webcam by my gf while she give some control to strangers in chat rooms. I would love to be able to hear the audio of those who watched me as the she gave out the link to as many people as she could.. maybe even from my contacts on my phone

  8. acehi491 says:

    My fantasy would be to be restrained face down. My knees would be on the floor or bed, but my chest and abdomen would be straddled on a padded hobby horse-type thing with my wrists restrained in front of me. In addition to shagmatic’s mechanical dildo sliding in and out of my ass, my dick would also be tethered to some sort of milking machine. I think the sensation of being simultaneously fucked and milked would be incredible!

    • shagmatic says:

      sounds like fun to me. quite a while ago i experimented with different joystick controllers that allowed you to jerk off with the same hand that was operating the controller. this allowed you to jerk yourself and fuck yourself at the same time. it was a little clumsy but it did work. some day i should figure out how to do it better. the thing i made was mechanical. i also tried different ways of sending motion including accelerometers but i am not especially good at using them. it seems that the only way to measure absolute position with accelerometers is to use them in conjunction with gyros and the code gets very complicated and i never found a ready made library. maybe there is something available now that would make the job easier.

  9. Steve says:

    Hello everybody,

    i a looking for someone, who would have fun to manufacture me the following sex machine. Unfortunately i am too busy due to my job, so i can’t do it by my own. I really hope for someone who likes to help us. Of course we like to pay a fair amount for the development. The sex machine request is the following:

    Basically, my wife`s fantasy is to be fixed and to be forced to bj dildos. I don’t wanna offend you so i try not to use strong words. In detail, i am requesting for the following: in the game are 2 dildos, mounted on 2 linear drives. The linear drives are controlled by a timeline based software. The software is able to control action start, stroke length, speed and so on. There is no need for an extra long stroke. I think 3-4 inches is enough. The program should be able to control an artificial ejaculation as well. As the 2 mounted dildos are “squirt able” dildos, the software controls 2 suitable pumps to transport and “ejaculate” liquid. It would be nice to have some adjustable parameters for this application as well like volume and interval. To put the cherry on the cake: Maybe it is possible to load some audio files into the program to match with actions and to accentuate the game. I thought of an Arduino based solution, but maybe there are better ways to do it.

    Who likes to help us?

    Waiting for your kind replies 🙂

    Best regards,

    Steve

    The Rubber Hand Illusion could be extended to your machine. If the shagmatics motion could be synced to a porn video it should cause the same kind of illusion. Namely, the shagmatic becomes the image you are watching. The motion could be recorded into the audio track of the video. It shouldnt be too difficult to fabricate a device which translates the linear motion of a dildo into an A B encoded logic or even decoded logic via an ELM404.

    • shagmatic says:

      I did succeed at recording and playing back machine control via an audio file. I have not had much time to do additional testing with this and also have one concern. Sine there is always some slip with the drive wheel system it would be difficult to maintain complete synchronization between the machine and the video. A direct connection between the motor such as a ball screw or timing belt and a servo motor with encoder would eliminate this problem but it makes for a more complicated and expensive machine. I have build some of thees and they are also higher maintenance. This is one of the reasons i have not put too much effort in to the record to audio. I hope to have time this winter to do some more testing. If anyone is interested in working on this I can share my methods but i would require a non disclosure agreement because this is one aspect of the project that took a huge amount of effort and i am not willing to totally open source it at this point.

      I have not used an ELM404 in my machines because I can do the same signal conversion in the arduino code. This is in fact how the rotary encoder is used to drive the stepper motor and provide signals for other functions as well.

      • patrick says:

        I think I can achieve a simple audio solution using standard sterio audio input. The only snag is the decoupling capacitors in the audio cards. It records a digital pulse as a brief spike. By recording the pulses sent to the motor and playing them back through a monostable I should be able to reproduce the motion. The direction is more of a problem to record via an audio card with its built in decoupling capacitor. My intended solution is to record the direction as a tone. Tone= in and no tone=out. A simple rc network will produce a hi for a tone and low for no tone.

  11. Spencer says:

    I was able to get bidirectional operation of the fucking machine from audio signals and demonstrated that I could record motion initiated by the joystick and play that motion back. I did not bother to do any more testing because, at that point, i was using a drive wheel machine which slipped so it was not possible to maintain synchronization. I have since built the timing belt machine and will soon be finishing a heavy duty machine that will most likely use a drive cable so it will also not slip. I will eventually do some more testing and see how good my recording method is. I did the initial testing with a simple circuit for connecting the Arduino to audio sources and targets but will probably test next with the audio shield. I am using the audio shield for my beat following program so i have a pretty good idea how to use it.

    My recording uses a modified Biphase Mark Coding. I was able to demonstrate that there was sufficient bandwidth in the audio (cheap low quality audio of a phone etc) range to record with sufficient precision and speed. A more conventional BMC scheme could be used if the motion data were processed in a clever way to allow this and i might give this a try when i have some spare time. The pre and post processing will bet a little complicated so i am not in a hurry to jump into this. If there is someone familiar with digital signal processing who wants to work together with me on this, i may be interested.

  12. Mike N says:

    Spencer, I’m having a hard time trying to decide if you two geek out more on the engineering, or the fucking itself. ; )
    Regardless, have fun!

    • shagmatic says:

      at least you are having a “hard time” i actually like both aspects but spend more time on the engineering.

  13. Here is a fantasy that I actually played out recently at my house. I wanted a hot boy to walk in on me while I was using my fucking machine. I met this boy on-line and he was totally into stopping by and watch the machine pummel my butt.

    Here is a link to my dropbox where you can actually watch the video:

  14. Alexisequal2xxx says:

    I’m a webcam model and I have a major fetish for being restrained and fucked by a machine. I own a cheap piece of crap that’s super noisy and the default speed is ridiculous. I have been wishing and dreaming That somebody would get me a machine for Christmas and as a lover of engineering and especially experimental audio electronics, this would be the most incredible thing I could ever imagine owning and oh my god, my audience would LOVE it. It would seriously give me life! I would be the ultimate spokeswoman, ideal girl to show the world how THIS is THE fuck machine and inspire other models to take on machine building and electronic engineering. If I had the time I would build my own. All I can do is wish for a miracle.

    • shagmatic says:

      I would love to see a shagmatic machine built and used by a model who could demonstrate it. This is not something I have time to build. Any readers interested in contacting Alexis and working with her? I have some new microcontrollers arriving very soon that I think might make the whole system even more responsive and will add the ability to add many options. I am going to post a message about this once I get the new controllers.

    • danapefq says:

      Hi Alexis! My name’s Dana, I’m a sex worker and a sex toy collector and I have been thinking about trying to build one of these machines with a couple of friends of mine. None of us have tried anything quite like this before but we all have some engineering and building experience. I love meeting other sex workers with similar interests and if our project turns out to be successful I’d be open to building more for friends. Feel free to get in touch with me if you’d like to get to know each other and swap some design ideas

      • shagmatic says:

        would love to see you getting a working shagmatic machine. it is not a huge technical feat to build one but it does take a little perseverance. hopefully you will get the help you need. please note that the firmware i have posted might not be the most current or perfect for whatever machine you are building. once you are farther along i can make sure you have whatever you need. i am still waiting to get one but i have really high hopes for the teensy 4. It will be a few days before I can test one but my guess is that this is the controller to use. More in a few days.

  15. ade says:

    shagmatic, the teensy 4 is awesome. But better still is the newer 4.1 – it will do ethernet without an external interface (just the magnetics on a small board).

    I’m interested in a fucking machine (also based on a linear drive for better controllabilty) but I’m also interested in vibrators and pleased to see there are some camgirls here. Every camgirl seems to have a lovense, but the lovense hardware is pathetic : just a weighted motor.

    I’m interested in building a better vibrator – a whole chair, more like that BMW bike or washing machine but with the audio programmability of a shagmatic. Do you think it also needs a penis or is the butt vibration enough ? Would love to hear what you think and maybe do some experiments. Especially interested if you’re in the UK as sending large devices over the atlantic is a bit of a nuisance.

    • shagmatic says:

      i am not familiar with the interests of girls. i think penises might be over rated. i will check out the new teensies. you must mean 5 or 6 series i am not aware of anything in the 4 sweries with wifi. i am using the esp323 for wifi but really hate the thing. very time consuming to program etc. would love to find a teensy equivalent.

      my machines are capable of vibration speed. in fact one of the most fum uses is to have it vibrate and thrust at the same time. you could get vibration alone with a very simple motor flywheel arrangement and not need belts etc if you don’t want thrusting. i have not released the audio follower code but it could be used to control vibration by some simple adaptations.

  16. Badjuju says:

    The fantasies part of this forum seems to have derailed somewhat, so to get back on track: My girlfriend is bi-curious. So my fantasy is as follows. I would love to come home early and unexpected. Accidentally walk in and see her and whomever she brings home in action with a Shagmatic that I built. The new girl tells a friend who is all too eager to experience everything her friend has described, and so on and so forth. Culminating in a multi-girl orgy with my girlfriend using the Shagmatic on herself as well as on the other women. The idea of many women cumming on and by a machine I built is very erotic.

  17. Graysass says:

    Hello All,
    This was a fantasy I had that I eventually did with an ex-gf. I have built two different machines over the years. The first was so heavy, large and super loud. It was made with parts I found in my apartment. It was so large that there was no place to store it when I wasn’t using it that was out of site. I live in a studio apartment. When I started dating this new girl I figured it best to get rid of the fucking machine. We hadn’t had sex and I had no idea what she would think seeing this beast propped up in the corner of the room. Not to mention if she had a closed mind about seeing what was doing me before her. To be safe I saved the motor and controller and threw out the rest. So at that time I was fantasizing about having a kinky partner that shared my interest in trying new stuff in search for the best orgasm. I imagined incorporating the machine into our sexual play. It turned me on thinking she would try using my larger dildos and if she was able to take them how great they felt. I know how good they made me feel and being able to share that same feeling with someone else got me really horny. I fantasized all the different ways we would use the machine. I imagined the machine fucking her ass while we were 69’ing. I’d think of it fucking me as I was fucking her. And my go to when I needed to cum quickly was her restrained doggie style with the machine fucking her pussy and me in her ass. Well I had to fantasize that for about a year more because she turned out to be real boring sexually. I missed the machine so I decided to build another one that was much smaller and would fit in a closet. It turned out much better than my first machine. So I was playing with it this one day trying for a HFO. About 2hrs of getting plowed by every toy I had and still no HFO. I was needing a break, but I desperately wanted to cum first. I was sweating bullets and the machine was going all out while I stroked my cock like a madman. I was starting to feel I was getting close and my phone starts ringing and the feeling was lost. I answer the call and it was a gal I hadn’t seen for probably 20yrs. She asked if I was still living at the same place and could she stop by and visit. Sure I’d love to see you do you remember where my place is I asked. She said yep. I asked when does she plan to come by so I can be sure to be here. She says how about right now. My door bell rings and my response was oh shit. I dropped the phone turn around looking at a masturbating scene of the freakiest kind. All my sex gear, toys, lube and homemade movies of the machine fucking me on the T.V. As I was just frozen there not able to believe what was happening I hear her voice from the phone on the floor are you going to let me in or what? You there? I pick up the phone and tell her I’m coming right now. I’m naked, sweating profusely and the room is as I just described. I unlock and open the door come on in I said and I turned and picked on of the towels on the floor up and tried to get the sweat off me. I sit down on the couch facing her. She was standing there with a blank look. I noticed she looked great for being over 60. She is 10yrs older than me. Not knowing what to say I told her she look great and not to just stand there, but make herself at home. She asked if this was a bad time she could come back another time. I said no just sit down and I’ll get all this put away it’ll take just a moment. Then from the T.V. real loud I hear me on the video moaning and grunting while this huge toy was tearing me up on the machine. We both are just staring at this I’m still embarrassed and not sure how to act other than to put away everything? She said, “that is you” Still watching it I picked the remote up and turned off the T.V. She turned to me and said I guess you haven’t changed a bit in all this time. Still getting freaky like when you were a young man. That’s right I’m going to be this way til I can’t touch my dick. She says to turn the t.v. on again cause it was hot watching me. That was what I needed to hear. I new it was ok and we would be fucking. I was standing there looking at her profile and thinking she was still a beautiful woman. I walked over next to her and asked her if she would rather watch the video or the live version. She said sure but first I want to do something, she looked at my cock and said,”Your cock has been dripping cum since I walked in the door and I’ve never had a better lover since you. Is you cum still as sweet as it was back then. I shrugged and she sucked my cock like she never had before, but she stopped and told me to show her how I use that thing. I lubed up the fat dildo and backed onto it. A gasp parted my lips and I started it slowly stroking in and out. When I looked next up at her she was almost undressed. I stopped the machine and crawled on all fours to her. She had just stepped out of her panties. I told her to sit back down and I pulled her ass to the edge of the couch and pushed her legs back and there was her pussy right in my face. I take both hands and gently part her lips and her clit sprung out like it was excited to see me again. I suck it into my mouth and start rolling it on my tongue hard with some rapid flicks with the tip of my tongue. I then notice how wet my chin was. I spread those lips lower exposing her soaking wet hot pussy. I raise up on my knees between her legs and slowly slid my cock into her so juicy pussy. I fucked her for a bit like this and I was ready to cum, but she was just getting into it so I lifted her off the couch onto the floor with me. I flipped her over grabbed her hip with one hand and grabbed a handful of her long red hair and pulled her back onto my cock. I looked down at her ass as I picked up the pace and notice she now had a huge tattoo on her lower back, a tramp stamp. I give her cheeks four or five nice crisp slaps. I looked down at my red hand prints against her white skin and thought what a tramp. I took my free hand and grabbed her shoulder and let go of her hair with the other hand and grabbed the other shoulder and started pulling her down on my cock as I thrust up in her. I could feel juice running down my balls and the head of my cock thumping against her cervix. She was moaning and grunting as she was slamming her pussy devouring my cock. She new I was going to blow and she starts begging,”give it to me in my ass!” I spit on her asshole never missing a stroke, but to late. I pull out and go to spear her tiny pink hole and cum was already squirting covering her hole still I thrust it in. It caught me off guard how easily my cock slide in all the way. I grabbed her by the hips again and pumped her ass for just a short time and held her tightly driving into her deep with each spurt of cum shooting deep inside her. I pulled out and collapsed next to her. She was like that’s it? Get back in me and fuck me til I cum. I’m like sorry let me enjoy this for a few minutes and I’ll do that. I didn’t hear her say anything. So I stayed there enjoying the after shocks and I hear her making a groaning gasping sound and it wasn’t next to me anymore. I open my eyes and she is trying to fit the huge toy I was using first in her pussy and now she was trying her ass. That just was so hot like my fantasy. I got up and told her she was for filling a fantasy I’ve been entertaining. All she said was you had this huge dildo in your ass? It is now my old favorite I’m actually saving for a much bigger one. That one barely stretches me anymore. I picked up my smaller Bam Dildo and said this might be better for you. I took the big one off and replaced the bam on the machine. I told her to get on her knees again and I had her back onto the smaller toy which she said felt almost to big. I started the machine off stroking slow and showed her how to control the speed I stood behind her watching her fucking the machine and she was just loving it. I stroked my cock til it was hard again and told her I wanted to fuck her ass now while she…I didn’t even finish what I was saying and she cuts me off and tells me shut up and get my cock it her ass. The memories of all the great sex we had so many years ago came back and I positioned the head of my cock slightly in her gaping cummy butthole and waited to hear her beg for it.I slap my hand across her cheek. I back out again and position myself to her side so I could paddle her ass accurately and with a better angle. I have a 3″ wide leather paddle that says slut on it like a rubber stamp. It actually works well on light skinned redheads. I start paddling each side and she is loving it. She’s got a bright red rump when I stopped and got back behind her and this time I lubed up my cock and told her to slow the machine down so I can get in. She slowed it slightly and I forced my cock in. It was so tight that when I would back stroke and the dildo was thrusting in here pussy her ass would push me right out. It took me a minute to figure out how far back I could go without being ejected. It felt so good and she wasn’t even talking words anymore. She was just moaning and screaming out like a possessed woman. She was fighting to stay in the action, but too many orgasms had wore her out and she collapsed forward and was laying there twitching. Now we had just change places because now she was laying there and I was still hot into it. I lowered the machine and positioned it so I could lay on my stomach and I got it going and layed between her legs and I spread her legs and told her to spread her cheeks. I was enjoying the toy fucking me and the smell of her ass aND pussy with my cum was so hot I breathed it in for a moment before I started to lap up her pussy juice. She jumped saying she was to sensitive so I moved forward and started tongue fucking her asshole. She was really liking this and she spread wider and relaxed her hole so it was gaping open. I could see my cum puddled up just inside. I swirled my tongue circling inside her hole. It was hot listening to her I stopped the machine and got up and asked her to fist my ass like she used to do. I pulled my knees back to my chest and she lube a hand I slide it easily in. She just said wow. I asked her to double fist me. The second hand went smoothly in so she interlocked her fingers so it was like one giant fist. She was rotating it at first and it was mind blowing. I was stroking pretty fast the she added an in and out motion at the same time. That was it, I said I was going to cum and she put her mouth over my cock and I had another massive orgasm. She stayed for a couple of days and we spent alot of that time naked pleasuring each other. We did almost every bucket list sexual things on my list. Only have a handful left and she can’t help me with them.

    If you read that all then it was worth writing it all.
    Btw- I have short vids of the two machines I made I just don’t know where to put them or if they would be something anyone is interested in. I can be reached at the email address below.
