Vacuum bed self-bondage with Venus pump

[Vacbedbound]

OK, i did it! This is me 1 hour ago, getting Milked in my Vacbed!
Wow, what a ride!

That's just plain cool! Any videos? (even a simple GIF should be enough for an EOTD 😋 ) Were you alone (aka vacuum bed self-bondage)?

[Vacbedbound]

Yes, it is selfbondage, but if i move my upper body the neckgarsket is leaking and i can get free, so it isn't.

 Here is how it works: 

On the Picture you can see the inside of my DIY Vacbedpump. 

   

These are the components:

1. Vacuumpump 12V with 60l/min (packed in some foam for noice canceling)

2. Magnetic valve 12V (normaly open and closes when under power!!!) 

3. 12V Akku pack ( it has Only 600mAh so it can give power to the pump and the magnetvalve for ca. 1hour) 

4. adjustable 12V Timer Relais  

5. adjustable Vacuumswitch (you can adjust a specific vacuum when it switches of the pump and switches on the magnetic valve. I adjusted it to -0,1 bar to prevent vacbedlines)

6. Power supy 12V (only for the Timer Relais.)

7. Relais 12v (to switch on the milkingmaschine)

8. Remote Control (to trigger the Timer) 

Here is the procedure:

I get in the Airtight Vacbed and seal it from the Inside.
I stick my Penis thought the hole and stick one arm through the neckgasket to stick the milkingmachine on the Penis. it sucks itself in place but doesn't start stroking yet. Then i push the trigger for the Vacuum pump and stick my Head through the neckgasket. The pump runns until the adjusted vacuum is reacht. Then the Vacuumswitch switches off the pump and switches on the magnetic valve and the milkingmaschine. If the Vacuum gets weak, because of some smal leackage, the pump starts sucking again until the Vacuum is reachd again. when the timer has ended the magnetic valve opens and i get free.

I know Vacbed Selfbondage is dangerous, but this is why i use a Vacbed with neckgasket (wich is not to tight) and tell a friend if i do a Session. All in All this works verry good and it is a lot of fun to be controlled by pumps and maschines. It is relative save, because i use a Akku that has only enotgh power to keep it running 1 hour.

Ingenious! I will move it to a separate thread. And I have more questions about the schematics, mechanics, timers, etc.!

I'm kinda jealous 😋

[Vacbedbound]

Sure, you can make a new thread out of it.
Then i will post more details.

I took some Pictures, but i set the repeating rate of the Photo Timer to low.
Next time i will try again.

Moved! Please tell more!

Ok, here is my part list:

The Vacuumpump:
Membranpumpe 12V Druckwasserpumpe Luftpumpe Kompressor 12V Vakuumpumpe 12V
I took the 40L/min air modell (sorry, i thought it had 60L/min.)
 It needs around 5 min to suck the Air out of the Vacbed 
and it is realy stong. If i wouldn't use the Vacuumswitch, 
i hab big Vacbedlines.

This is the Vacuum switch

You can adjust the Vacuum with a screwdriver. I took the lowest.
It is a changer Switch, so you can use it to switch something of
And something on the same time.

This is the magnetic valve:

Important is the NO function (means that it is open without Power an closes 
under Power.) it needs no minimal work pressure and Opens on Vacuum too. 

This is the Timer Relays:

This is the battery housing i use with 10 x AA Accu

The main problem with the setup is, that I can free myself by struggling with my upper body. If I move to much the neck gasket leaks. I don't want to use a Vacbed with the head inside, because I think it is too dangerous. The pressure on the ears an the risk of choking is to high in my opinion. I need an other solution. The neck gasket on my Vacbed fits good, but I think it is just a little bit to short. Maybe if it were a bit longer it would seal the neck much better. Like you see on the picture i am wearing a latex mask. I think about gluing that mask at the neck gasket. An other option would be leather collar fixed to the to the right and left tube of the Vacbed frame. I tried that With a leather Collar that i own. It has D-Rings on each side. I used two chains to connect it to the tubes. The result was, that it became tighter, because it was pulled to the sides. I didn't like that. I would like to try how it works with the leather collar fixed to a stiff metal bar at the back of the neck. That metal bar should have some kind of U-shape that fits to the neck and holds it in the middle of the Vacbed frame. maybe i will try that.

Only.... Wow!
What is the additional tubing on the Venus device?

[Vacbedbound]

The additional tubing at the tip of the Reciever is a modification i made. It leads to a smal Vacuumpump, that sucks air or any liqids out off the Venus reciever constantly. That sucks the Penis stronger into the Reciever and prevents it from falling of the penis because of liquid in the valv  of the endcap. That happens withe the original Venus sometimes.

If you look to the Photo precisely, you can see a wire going out of the receiver too. That wire goes to the head end of the vacbed and inside it. At the right hand side you can see my estim box inside the Vacbed, which is connected to a analplug and the reciever. In the reciever i use a conductive silicone liner from Serious kit. You can buy it on theyr website.

Sometimes I'm scared that thing sucks my Brain out!!!
