Forced insertion set-up

Post by KacieMx »

I've been through quite a few threads now with forced anal being the theme. A few setups had a buoy system, one with melting ice under a plate, another with ice melting into a bucket attached to a plug on a pulley system.

Anyways, I thought an easy, guided method would be utilizing two poles. One traveling inside the other. The outer pole would need a straight guide hole cut out length wise to act as a traveling guide on two sides if the pipe. Fit an eye bolt through the guide holes and secure with roller-ball bearings and cams to provide smooth movement. The inner pipe would slide in the top and rest on the eye bolt. Attach your dildo/plug to the top of the inner pipe, secure the bottom pipe to a spreader bar, floor mount, etc. And you now have a traveling piston. Total potential movement would be the length of the guide holes.
Using the pulley system, or another mechanical means, and you have a straight guided system with a limited travel plane for delivering your forced insertion scenarios.
I may draw this up if there is interest. Or I may just make it myself. We'll see. :roll:

What about a thread? If you thread the pole that hold the plug or dildo you could use any kind of motor to raise and, unlike all the other methods, also lower it. Its also very precice. I think ive seen something like that in an kink.com porn but i cant remember which one.

Um. Or use a slow linear actuator motor with a range of 200mm for 20$something and attach a plug to it. I have mine attached to a floor pillory.

How did you manage to secure yours in a vehicle position? I can think of ways to achieve this, but curious how you did it.

[boring elf n safety bit]

years ago I designed a model to demonstrate how a pneumatic ram works, without all the compressor/air control gear

I used a very small motor (a "speed 400" model motor) driving a worm gear/spur gear combination (30:1 reduction) which in turn rotated a length of 6mm steel threaded rod. This went through the centre of the model ram, and the "piston" included a 6mm nut threaded onto the rod, so as the rod rotated, the "piston" travelled up the rod or down depending on direction.

This assembly was unstoppable by hand. Now imagine the dildo/insertable travelling up the anus/rectum/vagina but not quite in the right direction and you can't stop it because you are restrained. Something has to "give" and it won't be the insertable !

Remember that wjhat you see on porn sites is pretend, its filmed with a crew, people are looking after the safety of the model even if it looks like she/he is in terrible pain (well, they might be, masochists enjoy it ! ) but serious harm is being avoided. Solo play doesn't have this safety net, so be careful. Very careful if you include mechanical systems.
be a switch, double the fun :-)

Bunch of pipes and pipe clamps :)

Will post a picture as soon as I get into the cellar.

LJ has a good point with the dangers of the motor system. Anything that forces something up an orifice with superhuman strength would be just about as bad as shooting yourself in the aforementioned orifice if things went wrong.

I can envision a system similar to an ice release to insert the dildo. You would have two telescoping tubes with a spring (of appropriate strength) pushing them apart, and a string holding them together via an ice cube. Once the ice melts the dildo will be gently yet inexorably thrust into the orifice of your choosing.

Unfortunately, the ice in your setup would melt too fast, as the string would apply constant pressure to it.
Thus the "gentle yet inexorable thrust" you envisioned will much rather become a very forceful, spontaneous insertion, easily capable of causing harm.

If the spring was too strong it would definitely be capable of causing damage via a "forceful, spontaneous insertion". You'd need to thoroughly test the device on yourself unbound by hand before using it for real, just like any other DIY sex toy.

Regarding the melting rate, I don't think it would be too fast. Before I made my electronic release, I used a 5 pound weight pulling a (rather thick) shoelace through an ice cube. It lasted me a good 10-15 minutes. With a spring providing a safe amount (2lbs?) of insertion force, I'd estimate it'd take around 20 minutes.

If it's tested, it's valid.
I just figured it could possibly fail in a harmful way. If you know it to be safe, have fun! :hi:

What about this modification? Attach a second pipe using a coupler. Fill the second pipe with ice and let the spring pull some kind of plug through the ice. As the ice melts, the dildo will be pushed in a slow, contolled manner. Melt rate for the ice can be varied by using different materials for the additional tube and plunger. A metal pipe and plunger will increase the melt rate. A reducing/expanding coupler would allow you to vary the amount of ice.

I created a very nice forced insertion setup if anyone is still interested.
I've used it twice, so this is not theory.
So the method is very controllable, very slow, and very smooth.
you need three buckets from the hardware store, home depot, lowes, etc.
two of the buckets need a small diameter vinyl tube (hose) connected to each other, on the side, but as close to the bottom as you can.
I drilled a hole, attached a nipple and sealed it with caulk.
with one bucket placed higher than the other, if you pour water into the upper bucket, the water will slowly flow to the bottom bucket.
As I discovered, if you don't purge the air in the line, the air will fight the water flow and nothing will move.
These buckets have a rim that makes them stackable into other buckets without creating that annoying suction, if the nipple was installed as close to the bottom as you can, you should be able to put another bucket into the lower bucket without it touching. If it touches, simply put an object into the bucket to prevent it from seating down too far.
So now you have a system that as you put water in the top bucket, it will flow down and cause the bottom bucket to float.
you can control this by how much water you decide to put in. if you put too much, simply put a piece of plastic etc. over the nipple of the top bucket and the water will stop flowing.

For the insertion object, it should be as light as possible, but yet still sturdy.
What I came up with was a funnel placed upside down. on top of the funnel was a 1/2 inch piece of pvc pipe to provide a rigid shaft to place the soft insertion object over it.

Cover the insertion object with a condom for sanitary/health reasons and to make clean up easier.

Finally, you need a potty chair to go over the bucket. These chairs are for handicapped purposes and are easily found. designed to go over existing toilets and provide arm rests. They can elevate pretty high with the adjustable legs.

I have not actually tried this while bound, I wanted the control of being able to get off if necessary.

But it sure was fun to try to relax as much as possible while the pressure very slowly built.

Sometimes I feel like an outcast amongst outcasts. In my mind, I believe I come up with brilliant solutions to overcome stated obstacles. I try to focus on simple tried and true concepts that are unlikely to fail, but implemented in new and creative ways. My ideas actually work great for me when I actually build a concept. But I get no validation from peers. Without anything to gauge my standing in society I start to question my worth to the community. Am I just unlikable? Maybe I'm too far above people's heads? Is my kink so far out there that I can't even fit in in a group of kinky misfits? I love predicament bondage. I've always felt at home here, but I hate the way it seems the only time I get feed back is when people want to tear down my ideas or lecture me on safety.

Sorry for the lack of attention, Born This Way. I have been reading your posts from before I was "born" here. I share the same passion for trying to create machines. What I lack, is the time right now. House half under renovation, I am just trying to build it up the way I want it, and finally get to live in it, take a break when its all done. Kink and hammer seldom go well together, and taking a day from that to create stuff would come back to haunt me later. I just can't relax right now.
There does exist a phenomenon that when a post is so perfectly written, others may not want to criticize it in any way. The poster is then left to believe there writing is unfit. I have observed that the culture here favours not making too much unnecessary noise or chatter just to say that they like your idea. I, and several other members I work with in the background who are charged with stimulating (giggity) the forum are trying to shift this.
I doubt very much that anyone has much to cut down about your ideas, and doubt even more that you are unliked.
Please don't be discouraged. I, for one, was thrilled when you returned. Send me a Private Message when you get a chance. Got something to give you a chance to go pro in this forum.
P.S., I used to think your avatar/signature combination was hilarious. Made my day thinking about it.
Bondage is like a foreign film without subtitles. Only through sharing and practice can we hope to understand.

Don't be discouraged by the seemingly little interest in your articles.
I like the solutions that people provide, especially those with ordinary utensils.
In a science magazine from this month there was just an experiment with roughly your setup of "Re: Forced insertion set-up/Postby BornThisWay» 24 Mar 2021, 04:27", but where the hole is in the middle instead of the very bottom (the liquid does not continue to flow from one bucket to the other until it reaches the level of the hole, but once it reaches the level above the hole, it works like a siphon and the liquid drains completely from one bucket to the other). Automatically. I had to think of your description to use this experiment in BDSM.
So you can see that even after some time your articles can still have an influence.
