Breathing System – AVON Upgrade Kit

Vendor: VAST

An Upgraded AVON FM12

Two months ago I showed you how to upgrade an AVON FM12 in order to make it ready to work with the VAST Breathing System. As some of you might have noticed, I used the S10 Upgrade Kit to upgrade an FM12. Back when the Breathing System was first introduced, it was the only upgrade kit available. As you can see, it works perfectly. But if you have an FM12, you can save you some trouble and 10€ if you buy the correct kit right away.

For the Breathing System to work properly, the gas mask needs to fit tightly on the face. This can be done using the standard straps of your gas mask. But for added fetish value, VAST offers a head harness made out of their Superior Latex. I will take a look at this add-on in a small bonus review coming December 6^th, Saint Nicholas Day in Germany.

The Mounting Insert with the different Tunnel Inserts

Construction

The Upgrade Kit consists of two groups of elements: One group is used to turn the standard mono-directional breathing of a gas mask into closed circuit for breath play. For this you first need to replace the front unit where the used air is exhaled with a mounting insert and sealing cap. Then you replace the speaking valve with an exhalation valve (S10) or change the breathing direction of the right GM40 port with a screw-in valve (FM12). The other group are a flashlight classic and a flashlight GO inserts and three simple tunnels (internal diameter: 40mm, 45mm and 50mm) you can screw into the mounting insert for added fun. To help you upgrade your gas mask, the kit comes with a stainless steel tool, silicone grease and plastic care.

All elements are 3D printed. For the first batches they sometimes used a dark blue polymer because it was sturdier so some of my elements are this shade. They have now found a black one with equal properties so you should get all black toys with the typical silky-rough surface of a 3D printed object. This manufacturing process also explained the price: Especially the larger items take hours to print and require a lot of polymer. Due to the small numbers these toys will be made cheaper manufacturing methods like die casting is not an alternative. So like with many kink toys you have the pay a premium for premium quality toy.

The Exchanged Front Unit and Exhale Valve

Being 3D printed, all elements fit perfectly into each other and are air-tight. The air seal is supported by the silicone grease which also makes all parts move smoothly. Do not use oil based lubrication for these toys! Oil and grease will damage and destroy rubber and latex! Since the gas masks, hoses and rebreathing bags for breath play are made out of rubber, you will harm these elements permanently.

Like most elements of the Breathing System the Upgrade Kit comes in a nice wooden box with foam cut-outs to store the individual elements. Since some elements are permanently installed in the gas mask, about half the box is empty after the upgrade process. But it is still a nice touch and adds to the value of the kit, especially if you want to gift it.

Playing with an Upgraded AVON Gas Mask

In order to use the VAST Breathing System with a (gas) mask need a model with two separate GM40 ports and unidirectional airflow (in through one port, out through the other). There are some rubber makers who manufacture specific breath play (gas) masks with these properties but they are quite expensive. Most military or civilian gas mask like the old UDSSR, German, Danish or Israeli ones only have one port.

The Installed Fleshlight GO Holder

Because of this VAST chose to offer an upgrade kit for the AVON S10 and FM12 respirators, one of the most common gas masks in the fetish scene. The FM12 already has two ports, the S10 can easily be converted to fit a second one. With a little bit of skill and strength, even a clumsy person like me can upgrade one of those masks. For people not very familiar with these gas masks, the steps are not intuitive and sadly at least my very early version of the upgrade kit did not come with instructions. Because of this I made this little tutorial. Once you have understood what to do and have the tools at hand, it should take you 10-15 minutes to upgrade the masks. The provided upgrade tool is nice and helpful. Without it I am not sure if I could have upgraded my masks because the blade of a screwdriver is narrow and has a straight blade. Still, please be careful when handling the tool because it has pointy ends. During the upgrade process I managed to give myself some small, superficial wounds.

If you do not want to play with a gas mask or don’t want to upgrade your AVON respirator, VAST offers a Medical Face Mask with a Splitter and a Superior Latex Head Harness to attach it to the head. This is good because sadly due to age, the Brexit and gas masks being export and import restricted armaments in most countries, AVON gas masks have become hard to come by, especially outside the UK. So it is good to have an alternative.

A Classic Fleshlight Turning the Gimp Into a Fuck Pussy

If you need the other elements of the kit depends on your personal playing style. I very much enjoy the tunnel inserts. They allow to facefuck or force feed the sub without taking him out of his gas mask/ drone headspace. Theoretically you could fuck him through the hole of the mounting insert but the tunnels cover the sharp edges of the thread. Also, unscrewing the sealing cap and installing a tunnel gave some very gimpy subs an extra kick because they are being manipulated like an object or refitted like a machine. The internal diameter covers the most common range of dick diameters. Though is you are very well endowed, the max. internal diameter of 50mm might be a bit too tight. If you struggle with tightness or want to enjoy the smooth friction of the tunnel walls, you can use both water or silicone based lubes to make your dick slide through more easily. To clean the tunnels afterwards, simply handwash them with warm soap water. The polymer the parts are manufactured out of is quite sturdy but I would not trust it to be dishwater safe.

The next level of objectification are the Fleshlight (GO) holder. The Fleshlight maker offers a wide range of designs from greedy mouth over slutty ass to technical, almost drone-like designs. Each different front has a different texture inside. So you can choose into what object you want to turn your slave into. Naturally the Flashlights are too long so you need to shorten them using a sharp bread knife. The final length depends on if you want a seamless transition from Fleshlight to slave mouth.

In order to Leave Space for the Sub’s Head, the Fleshlight needs to be Shortened

Some testees were driven wild by the look and headspace of turning their gimp into a fuck/ ass/ hole face. Personally, this did nothing for me. So my advice is to give it a dry run fucking the gas mask without a gimp because shortening it accordingly.

Some testees rightfully criticized that the upgrade kit is only sold with the different inserts and addons. They are a nice to have but personally I rarely use them and could very well live without them. Being big 3D printed objects they are probably a considerable part of the final kit price. Or in other words, expensive pieces of gear some people will have lying around unused. Because of this I would love to see the real upgrade parts being offered separately from the inserts.

However, I love the concept of the interchangeable front cover! I have already so many new cover ideas: An ash tray, a drink tablet, toilet paper holder, a chew gag on the inside, a piss funnel. The creative minds at VAST will probably come up with even more perverted ideas. So I look forward to the future of the system and its expansion.
