An Introduction and My latest Passion

[irishdream]

I had posted this under Techniques / Masturbation Toys, but it seems to be taking forever to be approved. So I decided to try posting it here in the forum.

I’m a commercial artist and I have always been good at building things. And I looovvveee to masturbate, always have. I first discovered the pleasure of my penis when I was young, I would rub my boner against my inner thigh and dreamy things happened within my body. My first orgasm was pretty young, the sensations I experienced left me with only one thought . . . Do It Again! I have had what I would consider a normal sex life, I have always had a partner in my life, all of them very active, yet my most amazing orgasms have occurred while masturbating.


Well through the years I have tried ohhh so many different ways to make that feeling come to me again and again. I have purchased and built many toys trying to achieve yet another unique experience, solo style.


A while back I decided to try to build my own Blowjob machine, I wanted to be able to lay back, close my eyes and just enjoy the sensation.I figured there had to be a way to make it from components that are readily available, just about everything I used I got from Amazon. I did some research online and tried to break down how the existing machines work, the core mechanical principle is they suck in and blow out. I had built my own Fuck machine awhile back which was a good learning experience about linear actuators and what size motors are needed for sexual pleasures.


I started with the idea of getting a pump that could attach to my Fuck machine, it already is creating a pumping action, so I started looking for a viable pump. I ended up settling on a 200cc mechanic’s extraction hand pump. Its displacement is ideal, it was a cheap investment and it could establish a proof of concept. After a little tinkering I had done just that, it worked! I first tested it on a dildo, that thing was a huffin and a puffin! I wasn’t sure what it would do to my dick! I even had a vacuum release valve in the tube to the receiver that I held in my hand just in case things got out of hand:)


The sensation was amazing! It’s very similar to a real blowjob, but it has such a steady rhythm that it can be mesmerizing. My first receiver was made from a 2 inch wide by 6 inch long piece of tubing with about a 3 inch piece of the tail end of a fleshlight sleeve attached to it. The sleeve grasps my shaft like a pair of lips and it sucks you into the tube and then pushes you back out. I started slow and gentle and was rock hard in a matter of minutes, on each suck my cock would pulse, wanting to get even harder. I turned up the speed and it started gobbling on my cock, I had a lot of lube in there and it was slobbering and slurping on each stroke. It wasn’t long at all and I was on the verge of an orgasm, my head was spinning with the thoughts of what I had just created, the pleasure rippling through my body was like being hit by a wave, the burning pleasure of my orgasm rumbled up my cock and it began pulsing cum into my creation. I had the biggest grin on my face after that!


I then decided that I wanted to make it a standalone machine instead of an attachment for my Fuck machine which was a very long and cumbersome configuration. Although I still think the concept has merit, an accessory that uses the existing power could be an inexpensive alternative for others. However, I thought there might come a day that I would want to use both machines together!;)


It took a bunch of refinements to get to where it is now, troubleshooting issues with the mechanical operation and then coming up with ways to resolve them. It’s not as quiet as I would like but it is working beyond my expectations. I put a longer tube on the pump, now it sits under the bed, much quieter.


Another thing that I realized after getting the extractor pump is that it is a very good size as a receiver, at least it is for me. I cut off the threads for the cap, leaving the outer rim in place and rounded the inner edge so the entrance is nice and smooth. I can place sleeves on it that wrap around my shaft giving awesome sensations. Sleeves are cheap and I’ve been experimenting with different ones and have found a few that are just amazing, they all give a different experience.


I purchased a Venus 2000 receiver, which you can get for about $40 and it works great with this pump. It has a really nice feeling to it, I can see why it is so popular. But to be honest, I'm really digging on my own receiver configuration, depending on how I set it up, it can be rough and aggressive or soft and sensuous.


I could share some more technical writing about it if someone is interested in trying to make their own. I’m just so excited about this toy! It can be hard to have a successful project like this and have no one that you can show it to. I had to find a way to share it with others.

Nice work! I love the dedication you put into this blowjob machine. It looks really nice and I bet, it really gives you a good time. Thanks for sharing!

[irishdream]

My DIY Blowjob Pump Ver. 2. I didn't really need to build a new one, but I found an excellent new motor on Ebay that was a little more powerful, a touch faster and a great price, so I couldn't resist! I paid more attention to the alignment of the piston arm to the bearing block to the motor axel. This one runs smoother and is much quieter.

https://u.cubeupload.com/IrishDream/NewPump.jpg

I took it for a test drive and at medium rpms I was getting 4 inch strokes on my shaft, it was slapping onto my pelvic bone on each down stroke, and when I closed my eyes, it was like I was being fucked by some mysterious woman hovering over me! My god, did I blow my load!

Thank you Sultan for the encouragement, the dedication is paying off in sweet dividends!!

[oldfan]

Wow, beautiful machine! If I had one of these I would never leave the bed!

It reminds me of the "Orgasmatron" from the movie "Sleeper"!

[irishdream]

Hey Oldfan, I haven't thought of the movie in years! It was quite risqué in it's day, gotta love some Woody Allen!

So, I thought it would be useful to share how I control this contraption. It’s one thing to get the pump operational, but to get it to perform as you want it to is another issue all together.

Controlling stroke length: If you look at the photos of my pump, you will see a wing nut that connects the pivot arm to the actuator. If you loosen it, you can move the actuator closer to the motor axel or further away. This adjusts how long of a stroke the pump will put out. If you just want to focus on the tip of your cock, make it a short stroke. It's adjustable.

Next, here is a link to a photo of my controller that I have next to me as I’m using the machine.

https://u.cubeupload.com/IrishDream/Controller.jpg

On this I have the power adapter which has a dial to control the speed. The rating of this devise is important, it must be able to provide the correct voltage and amperage for your motor to perform correctly.

And mounted below it, I created what I call a blow back controller. To explain, the pump sucks in a certain amount of air, which sucks your shaft into the receiver. Well, the same amount of air is then pushed back out of the receiver which will make the receiver pop off your cock, which I found to be troublesome. The blow back controller starts with a T connector where the tube from the pump feeds into and then on to the receiver. On the third outlet of the T, I put a one way check valve, which will allow air to escape on the blow cycle and closes on the suck cycle. I followed that with a shutoff valve that allows me to restrict how much of the air escapes.

I start off with the shutoff valve opened so the receiver is mostly sucking with less blow back. Once my cock is rock hard I can close it down increasing the blow back until I’m getting the maximum stroke. This is especially useful for the Venus 2000 receiver.

Keep strokin’ my friends!

Hi Irishdream,

Very interesting design my friend, was looking at your pictures more closely and curious about the receiver, most receivers have replaceable sleeves but looking at yours seems not to have one, correct me if wrong, I take the intake of receiver is a modified fleshlite, the main reason I ask is sensitivity after long use, I have heard people using Venus 2000 type milkers that the friction due to certain sleeves can be uncomfortable after some use and looking at your design may elevate that, when I built my machine I always felt the sleeves were a bit rough after few sessions, the more I think your design is well thought out so you can enjoy it longer without discomfort. Well done and thanks again for sharing.

[irishdream]

Hey Heatfun,
I appreciate your feedback my friend! Yeah, I have noticed a certain amount of desensitization after an extended amount of use, but it hasn't done physical harm. I've been taking a break from using the devise for a few days in a row, which has been hard to do! I mean you can have a blowjob whenever you want! While I've been working on this toy, every time I made an adjustment, it was like, well, let's see how it works now!

I have a Venus receiver, I had gave them my specs to build it for me, a piece of tube with a stem attachment, a cap and rubber tubing. It is a tight fit, and I did find that if I don't use enough lube or if you allowed it to dry out, it could get uncomfortable. I do have to say, I think it's an ingenious design, especially how it keeps the messy bits away from the pumping system.

In my photo called My Setup, the receiver doesn't have a sleeve attached to it, yet. When I have a raging hard on, it just slips into it with about a 1/8 in (3mm) gap, I don't fill the whole tube though

If you look at the following photo, it shows the receiver with two different sleeves attached to it.

https://u.cubeupload.com/IrishDream/Reciever.jpg

The one on the left is pretty loose, especially if you don't have a hard on, so it can be pretty sloppy, which I think is fun! However as you harden up the sleeve grips your shaft quite nicely and it makes a pleasant slurping sound which is very erotic!

The blue one on the right is my current fav, It's snug when your hard and has small ribs running up the inside. I like this one slow and easy so you can feel the ribs ripple up and down your shaft. When you run it fast, it turns into a blur of stimulation which is intense! But after a few minutes of that, if you haven't cum, your cock becomes numb to the stimulation.

Another detail about the receiver, if you allow the head of your cock to get too far out of the hard plastic tube of the receiver, it can suck in the soft sides of the sleeve in front of your cock, it doesn't hurt but it brings the action to a halt. So the stiffer the sleeve, the further out you can allow your cock to slide back into the sleeve. On the soft sleeve I set it so the tip of my cock stops just an inch away from the receiver, that way the head gets squeezed in the sleeve and then sucked into the tube.

I put two or three pumps of lube into the sleeve, squish it around to coat the inside, slide my cock into it and then snap it into the carrier. I always start slow and gentle, your cock is enveloped in a snug slippery tunnel. If your soft it stretches your placid dick into it and then squishes it back into the sleeve, it doesn't take much of that to get a hard on! I'll hold the receiver down so it doesn't spit my cock out until I'm hard. Once you get to there you can just let it do it's little dance on your cock, I'm getting horny now, but I just finished my weekend romp with a big load last night! Going to try to go till Thursday before I use it again

I'll share more about the receiver carrier another time, it's a big part of what makes this thing work so well.

Stay horny my friends!

Hi Irishdream,

Many thanks for your lengthy in depth explanation of your setup, brings back so many memories when I was building
my project few years ago, I remember the anticipation trying different things and "leaking" like mad before use hehe..

You have given me inspiration to build a new version 2 male milker, I like you have the option of different old fleshlite sleeves depending on mood etc, I got my receiver from Seriouskit here in UK, not cheap but quality piece of kit, you could buy different size sleeves to try, just wish I still had it and not chucked out. Was looking at Amazon for reciprocating linear motors, looks similar to fucking machine mechanism, one I looked at was 24v with torque of 40lb
but looking at the motor looks not strong enough for long strokes, my thinking is if I get one could always upgrade the motor eventually, another thing need to get my head around is the blow back valves etc, take you can get that on Amazon as well. I am tempted to give this another try but in no hurry to build it, maybe plan to have something up and running for wintertime at year end. All good stuff and yes keep horny...

[irishdream]

Hey Heatfun,
Send me a PM if your interested in getting a parts list, I'd be happy to share that with you. The sleeves I'm using are different ones that I've got on amazon, Some call them pocket pussies, hey they're cheap, so if I don't like them, no worries. I've been cutting some of them up trying different configurations.

So here’s the breakdown on my receiver carrier, it’s what makes it a hands free experience.

I’m using a flexible goose neck phone holder that I removed the phone holder from, It allows me to position the carrier wherever I want, so it’s adjustable. Attached to that is a drawer slide, this allows the easy up and down movement. I used two pieces of 1x2x4 inch wood to connect the hardware, you gotta have something for the screws to drive into.

Attached to the piece of wood is a small bungee cord that keeps the drawer slide in a neutral position giving the receiver room to be pulled down by the suction and assists with the up stroke. And a steel spring clip that I can snap the receiver into, this makes getting started much easier. I can lube up the receiver, stick my cock into it and then snap it into the carrier. And I’m off to the races!

Here are links to pics

In the background you can see the receiver in another phone holder that I use to assemble the receiver and to watch movies on my phone.


The Receiver in the Carrier:

With yet another test sleeve I’ve been using, it’s pretty intense!

I happen to have a tall headboard on my bed that allowed me to position a piece of 2x2 over my bed that I have the receiver carrier clamped onto. I have also taken it out of the bedroom and clamped it to a table, I can get a blowjob standing, sitting or laying down!

Stay horny and keep strokin’ my friends!

[heatfun]

Hi Irishdream,

Thanks again for info, the more I read about your design the more I like it, the receiver setup is interesting, like the idea of the rail to keep it stable, think this is very important for prolonged enjoyment of the toy, I also like the way you have trailed the fleshlite sleeves, when I had my setup I felt the internal sleeves inside the receiver tube was rough in texture after some use even when it felt smooth to touch. I am interested seeing your parts list and will ping a DM soon. Keep horny and enjoy your Thursday session...

[irishdream]

You wanna know what can be difficult? Trying to decide which sleeve I want to use, check out this pic

Sleeve Collection:
https://cubeupload.com/im/IrishDream/SleeveCollection.jpg

The top left one is Doc Johnson’s Super Sucker, it has thick walls and they don’t collapse as easily on the suction stroke, so your cock can slide out into the sleeve further. It has a silky smooth interior with subtle textures and is a snug fit with a hard on. Because of its weight, it moves with more momentum, so it can be a bit of a crouch slapper, I like to use this one slow and steady, It’s a nice grind!

They all have different textures, for me, the stiffer more pronounced textured ones can be a bit too much, so I’m like hey, why not cut them apart and use pieces of them. It’s like putting different lips onto the receiver.

In the bottom tray, you can see some slim walled silicone tubing, I’ve been layering one of these within another sleeve. It’s a unique sensation because when the head of your cock leaves the receiver, it passes through this tubing and it spits it out into the sleeve. Then on the suction stroke the walls of the sleeve are sucking your cock up until the head of your cock hits the tubing, then the suction is taken over by the tubing and it ripples down your cock pulling it through the sleeve. I’ve never felt anything like it before.

Stay horny my friends!

You can thank RandyMandy for this!

Geez, they sure do make you jump through a lot of hoops to show your pecker in public!

[irishdream]

Well since I’m laying all my cards on the table here, I might as well share how I set this thing up. It’s not as difficult as one would think.

To connect to my headboard, I made an L shaped device, one leg is a wedge that I slip between the wall and the headboard. Otherwise it lives tucked between the wall and my dresser, out of view.

Here’s a pic of it:
https://u.cubeupload.com/IrishDream/HeadboardMount.jpg

I clamp my receiver carrier to that which I keep in the closet.

I keep the pump under the bed, I just have to pull out the tubing that I keep with it.

The controller is in my nightstand, I throw it on the bed and plug in the tubes and the power. I use quick connectors for everything, it’s simple.

Finally, I slip a sleeve onto the receiver and add lube.

Done and ready to use. I can set up and take down in 3-4 minutes.

Clean up:
The receiver is made of plastic and stainless steel, I use water based lube, nothing a little hot water and a bit of scrubbing won’t handle.

Here’s a link to another video of me using it, this one gets right to the point, check it out!

Wow...those of us that don't have the skills can only sit back in amazement at the wonderful machine your built! It would be fun watching you building/tinkering with it, and then trying out the latest adjustment. That last video you posted is so hot...love the soft sucking sounds it makes pleasuring your cock. Great job and thanks for the posts!

[irishdream]

Thanks Neptune for the kudos! It is a really fun toy

I've provided plans and tips for those who have some wood working skills and a little patience on my website.

Cheers,
Irish
