ToyTorture’s Stocking Stuffer II – VAST (Smart) Watch Straps

The VAST Watch Strap, a Latex Strap for Smart Watches

Flagging what you are into is an important aspect of kink life. You never know where you might find your next (play) partner. Especially in vanilla or everyday settings, a wide wrist band in hanky code colors can be out of place or raise uncomfortable questions.

For those of you who are wearing a smartwatch, VAST has developed a nifty accessory: Straps with connectors for most current models from Apple (79€), Samsung and Garmin (69€) for example made out of their Superior Latex. The base is a wide wrist cuff style strap with a hole in the middle. With this hole the sensors on the bottom of the smartwatch can still get skin contact, tracking ALL the bio functions. Through slots the actual watch strap which fetters the watch to the wrist is threaded. It is closer with a sturdy and comfortable stainless steel roller buckle like on all other Superior Latex products from VAST. This design makes the strap quite versatile. For a more inconspicuous look, just wear the strap and it looks like a normal watch strap just with the unique latex feeling and horny latex rubber. For a more bolt statement add the cuff. You can even mix and match colors of the cuff and strap to either display different hanky colors or align the look perfectly with your gear.

Some Examples of the 12 Possible Colors for the VAST Watch Strap made out of Aramid Reinforced Superior Latex

If you want a latex watch strap, Superior Latex is the material to go to. Between two layers of thin garment latex, a layer of Aramid is glued giving it super-strength. I have several heavy play gear pieces like a bulldog harness or restraints and they have weathered years of hard play without showing any signs of giving in. So even when you catch the strap on something, there is not risk of tearing it and loosing your watch.

But as sturdy as the Aramid makes the latex, it is still latex. Thus, in theory latex is not an ideal material for everyday usage. UV radiation and all forms of oils will make it chewy quickly and will destroy it over time. This includes the oils in perfume, deodorant and even the skin oil every human produces. In order to enjoy the watch strap as long as possible, at least wipe it clean with a damp towel after wearing it. If you really want to treat it, wash it with a special latex detergent like VAST’s Wonder Wash and polish it with silicone lube afterwards. Yet, like every other piece of rubber and latex gear, enjoy it while it lasts, knowing it is not forever. And when you are a rubber fetishists, there is nothing like that very special touch of rubber on your skin, that very special scent. During my undergraduate studies, I wore a rubber wrist band for year on a daily basis. Having a light latex scent wafting around me, helped me pull through many of life’s necessities.

The VAST Watch Strap in Leather, probably more Longlasting but not as Comfortable as the Latex one

So while this wrist strap will not be with you forever, I can imagine that along the way, it will be a hot looking and horns inducing companion, either complementing a fetish outfit or bringing a kit of kink into your everyday life.

The straps also come in black briddle leather (89€) with laser engraved stitching, giving the strap a both rustic and modern look. Depending on the hide, tanning and treatment briddle leather can very stiff with firm edges and taking long time to be broken in. This can make wearing gear directly on the skin uncomfortable, making it not my intuitive leather choice for a watch strap. While the edges look not deburred or unburnished on the pictures, I doubt that a brand like VAST would release a stiff and scratchy wrist band. But without having felt it myself, I cannot recommend it unfettered as a gift for a leather lover.

eVac Duo 800

The VAST eVac Duo 800 with all the Accessories

Vendor: VAST

2½ months ago I reviewed the updated eVac 2.0 from VAST. While it was a big improvement ergonomics wise to the five year old previous model, being a monopole needing a second pole to work for e-stim made it hard to handle in some situations. A couple of weeks ago VAST also released an update to the old duo-pole eVac. In this review I will look at the differences between the toys and how this toy works. So I recommend you read at least the construction section of the eVac 2.0 review before reading this one.

Construction

The eVac Duo 800 has the same basic design like the eVac 2.0, has the same 220mm length and is 3D printed out of the same polymer. As the name indicates, it is considerably larger at 80mm internal diameter. Inside are now two stainless steel rods. One sound like with domed attachment, one with a flat segment plate which sits in the top half of the cylinder in order to press against the pelvic area. Theoretically you could change the position of the two but that does not make sense for ergonomic reasons.

The Nuts holding the Two Rod Electrodes in Place

The nuts holding both rods in place are sitting next to each other on top. Because they are so close to each other, the nuts don’t have wings anymore for tightening but just small studs for better grip. In order to tighten the screws tight enough for a vacuum seal, a winged tool is included will grips the studs and thus allows for more torque.

Having two rods, the eVac Duo comes with two plugs to seal the cylinder when you are not using both or any of the rods. The hex key from the eVac 2.0 has been replaced with a small screw driver which is also now the standard for all eVacs. To ensure the longevity of the toy, a small tub of Wondergrease silicone grease is included. All the accessories come in a small drawstring bag to keep all the accessories together.

The Plate Electrode as a Counterpole for the Sounding Electrode

Playing with the eVac Duo 800

Since the eVac Duo has the same ergonomically shaped base, it has the same great and quick vacuum seal. Having a larger diameter and thus more volume, the Duo behaves a bit different. It takes longer for the vacuum to take effect because air needs to be evacuated. Because of this the vacuum comes a bit softer and can be more gradually increased. But it also means, you need to pump more. If you or your bottom are petit or skinny, ensuring contact between the skin and the cylinder feet is a bit of a challenge, especially when he starts moving his legs. Due to the larger footprint, the cylinder has a considerably larger leverage.

The Duo addressed the issue that the sounding electrode needs a counter pole in order to create a close electric circle. This electrode could either be a pad electrode which due to the lower mass could be ending up the spot where the sensation is felt or an anal electrode with is relatively far away resulting in cable chaos or a loop around the balls which can create unintended leverage effects when wiggling, breaking the vacuum seal. Now the second pole sits inside the vacuum tube. The bottom plate is very mass rich and covers a large footprint which ensures that the sensation is felt on the sounding electrode. Additionally the 4mm banana jacks sit next to each other which makes wiring easily.

The Sounding Electrode with the New Hex Toll for Easy Adjustment

The placements of the electrode offer the door for a new deviant form of play: Take the sounding electrode out, seal the hole with the plug, put a very mass-rich anal into your sub (yes, this leads to cable chaos again) and start pumping. Since the dick is most likely pointing downwards, the e-stim sensation will be felt at the pelvic area. If you not start to stimulate the sub and increase his arousal, causing the dick to jump upwards, the glans (and sometimes the shaft) makes contact with the rod, creating a tickling shock. If you really want to shock your bottom, you insulate the bottom of the contact plate with a piece of rubber. Then the only conduction point will be where the dick hits the rod, most likely starting to jump uncontrolled due to the pain, making contact again and again. Until this vicious feedback circle makes him get soft and most likely continuously touch the rod or top of the plate if he is not too small.

Left: eVac Duo 800
Right: eVac 500

Since the counter pole plate is made out of stainless steel, it conducts the currency very well, even without waterbased (special e-stim) lube for enhanced conductivity. In order to achieve a smooth e-stim sensation, the complete surface should touch the skin. Otherwise it will be a very pinchy experience. When adjusting it, be a bit careful and not pushing too hard. The leverage could otherwise push the cylinder off.

The eVac Duo 800 serves also an unexpected market: Vacuum cylinders for big boys! I can count myself lucky to have a few play buddies who have 6+cm dick diameter and who have a hard time finding accordingly sized vacuum cylinders. Naturally they are also on the far side of the length spectrum so 220mm length is a bit confining. But if you are having the same issues, VAST is probably able to print you a longer cylinder. Though if you exceed 250mm, the rods will be too short to stick out of the top.

Conclusion: Excellent large vacuum cylinder with an integrated duo pole e-stim circuit

eVac 2.0

Vendor: VAST

The VAST eVac 2.0 Disassembled

Exactly five years ago I reviewed the original eVac from VAST. Back then, we were all stuck at home, having too much time on our hands to play with ourselves. So let’s see if this second edition is a real upgrade, especially now that we are playing in sex clubs much more again.

Construction

Like its predecessor the eVac 2.0 is a standard vacuum cylinder. The tube has an internal length of 220mm and comes in two diameters: 50mm and 60mm. If you have a really big dick, VAST can probably make you a custom larger one to fit your junk. Laterally on the domed top sits a standard vacuum valve from CPC which is compatible with all common vacuum pump hoses. The tip ends in a thread with a wing nut which is essential for sealing a vacuum around the accessories which turn the eVac (2.0) a unique e-stim toy.

Unlike its predecessor it is not made out of acrylic parts glues together buy 3D printed, making it both lighter and more nimble. The ready to use eVac 2.0 with the half-dome weights 350g vs 440g of the old eVac in the same configuration. So even when the sub wiggles a lot or you want to move around during selfplay, it sits more securely. Another advantage is easy cleaning. Both the tube and the stainless steel rod are dishwasher safe. The aluminum half-sphere is not! After a dishwasher cycle, both the seal and the thread are degreased. In order to create a secure vacuum seal, use low viscosity silicone lube.

The Thread on top with the Wing Nut unscrewed, Electrode inserted and the Plug ready to replace the Sound

While the old eVac was a bit clunky, the 2.0 is almost stylish. The coloring caused a bit of a dispute among my testees: Unlike the clear acrylic of the old model, the printing polymer has a dark steel blue color and is opaque. Silicone oil will make the material a little bit more translucent and will make the growing dick glide up the walls more easily. Both the tube and the stainless steel rod are dishwasher safe. The aluminum half-sphere is not! After a dishwasher cycle, both the seal and the thread are degreased. In order to create a secure vacuum seal, use low viscosity silicone lube.

 

Another big advantage of the new manufacturing technique is the anatomically shaped base. The old one had a flat, almost absurd wide causing leverage problems base with a rounded edge. The new one not only distributes the pressure more evenly around the groin but creates a better and smoother vacuum seal, even when moving around.

The eVac 2.0 comes with two accessories to put into the thread on top. The first is a simple, yet essential one: A small 3D printed plug with an eyelet on top to seal the tube. When this plug is inserted, you can use the eVac 2.0 like every other vacuum cylinder. The star of the show which gives the eVac its name is a 280mm long stainless steel rod. This rod comes in 8mm diameter (what I chose) or 10mm diameter for the more advanced player. The rod diameter is indicated by the last to digits of the product namen; my eVac 2.0 with the 8mm rod is aptly named 508, the 10mm version would be names 510. One end is rounded, the other is has jack for a 4mm banana plug. The final accessory is a milled and polished aluminum half-sphere which flows into a short tube on top. The aluminum not only safes weight but enhances conductivity. The rod fits through the tube and can be fixed in place with a small setscrew using the enclosed hex key.

The Anatomical Shaped Base

Everything is packed in a drawstring bag for easy and scratch-free storage.

When I first read the price, I was surprised. A good acrylic vacuum cock cylinder which does not have and ergonomic base costs around 100€. A premium of just 80€ for the e-stim/ sounding capabilities is more than fair.

Playing with the eVac 2.0

First, let’s look how the eVac works as a simple vacuum cylinder. In order to use the cylinder, loose the wing nut, put the plug into the hole on top and tighten the wing nut again. Due to the seal inside the wing nut, the cylinder is now completely seal. Now you just need to put your dick into the tube, attach your favorite vacuum pump to the valve and start pumping. Since the cylinder is on the shorter and narrower side of size, you can quickly create a strong vacuum. This is actually an advantage since most people overestimate their dick size and buy too big cylinders for an even and comfortable vacuum.

Having played with vacuum cylinders for almost a decade, the anatomically shaped base is a game changer! It makes wearing the cylinder so much more comfortable and creates a quicker, more secure seal without adding uncomfortable pressure. While other cylinders due to their flat base can become comfortable over time due to leverage pressing against pelvic bones, I did not encounter this using the eVac 2.0.

The Banana Jack on top of the Sound

While the eVac 2.0 makes pumping and wearing it for longer periods comfortable, two small pieces of advice regarding pumping:

  1. Pumping does not make your dick larger! There is an urban legend that exposing your dick to vacuum over extended periods of time, makes it grow. That is a myth! The dick will temporarily become a bit bigger and squishy. And yes, the more intense circulation and usage will help your erecting be stronger and harder (that’s why vacuum pumps can be used to treat erectile dysfunctions). The dick might feel bigger and longer due to that. But it will not grow.
  2. What can happen if you pump too quickly with too strong vacuum that you damage the tissue inside your dick. Then your dick will be constantly bigger but just squishy. This is aptly called “Sponge Dick”. In order to avoid it pump slowly, carefully and not going to the max vacuum. There should always only be a (light) horny draft, not painful suction!

The material this toy is made out of caused some discussion under my testees. Some drone players loved it for the dark, complete coverage look. Others did not like that you cannot see what is (happening) inside. In good light conditions, you can see the shadow of the meat inside. But under sexy darkroom lighting it is almost impossible to make out if there dick is touching the electrode or not. For many pump pigs, seeing your dick grow inside the cylinder is a big part of the turn on. This is of cause not possible with the dark, almost opaque material.

The eVac with the Plug for Only Vacuum Play

What sets the eVac apart from other vacuum cylinders is the central rod you can istall using the wing nut up top. The rounded tip is made for easy urethra insertion. Before putting it into your dick, you should disinfect the rod properly to avoid infection. Afterwards generously apply (sterile) lube and put the tip into your piss slit. Afterwards generously apply (sterile) lube and put the tip into your piss slit. The most common lube is water-based which had good conductivity and is easy to clean. An pro-alternative is silicone fat (= high viscosity silicone oil). It has a lower conductivity than water-based lube so you have to crank up your box a bit more. But unlike water-based lube, it does not get absorbed by the surrounding tissue or washed away by pre-cum. So when you plan on playing for longer periods of time, give that a try. Though it is a bit messier to clean. Since the rod does not move inside the cylinder, the process takes a bit of practice. The best way to do it is to unscrew the wing nut so the rod can move freely, push the rod all the way down and insert the sound outside the cylinder. Then hold the rod while pushing the cylinder onto your body, tighten the wing nut and start pumping.

The eVac 2.0 can now also be ordered with an 8mm rod which is 2mm less diameter than its predecessor. This should make the sounding part accessible to more people. When it comes to sounds, 8mm is actually the sweet spot between still being able to take it comfortably and not being “pointy”, thus getting down gently. Still, for an inexperience player, 8mm is still significant to pass through the sphincter inside on the tip so some prestretching is recommended.

The Anatomical Shaped Base

There are two ways to get the sound deeper into your dick. First, you can of course unscrew the wing nut and push the rod deeper. In some instances this can loosen the vacuum so you have to re-pump a bit once you have tightened the screw. The other – and unanimously voted hotter – way is by increasing the vacuum. The dick will temporarily increase in size, thus sucking the sound in deeper and deeper.

If you add e-stim to the play, it is getting even hotter! The more contact the dick makes with the rod, the lower the e-stim sensation is felt. It is only subtle, but noticeable. If you then break the vacuum and the dick shrinks a bit, the e-stim sensation will become a bit more intense again.

Of course, in order to create an e-stim sensation, you need a second pole. This could be a conductive rubber loop around the balls or an anal electrode. The e-stim sensation is always felt at the electrode with the lower mass and the smaller contact area. So if you just use a conductive loop, be prepared to only feel the sensation there if the rod goes DEEP. VAST also offers a cylinder eVac Duo 800 with an Ø80mm vacuum tube and a second conductive rod which pressed against your pelvis which costs 269€. I did not have a chance to play with it so I cannot tell how well it works. But if you are looking for a completely integrated vacuum e-stim toy, check it out.

The Bell-Shaped Electrode Attachement

For those of you who do not like sounding, the eVac 2.0 comes with a bell-shaped half shell which can be attached to the rod using a setscrew and a small hex key. This accessory can either be used to limit the depth the rod can go into the dick or if you fix it at just the tip of the rod as the contact surface. Then the half-dome envelops the hard glans pressing against it. Since the contact area is larger, the e-stim sensation is smoother. Depending on where the frenulum presses against the electrode, it can get stimulated intensely which lead to a handsfree orgasm of two testees. Be aware, that cumming from e-stim takes practice and does not come naturally! Most people who start out with e-stim hope to easily cum from it which is the exception, not the rule. While I am on the topic of warnings, be extremely careful when the bottom wears a piercing! As I said, currency always takes the route of lowest resistance which as soon as it touches metal is that focused path. Be extremely careful when ramping the sub in, especially when he is uncut and the Prince Albert is covered by foreskin. If he gets hornier, the foreskin retracts and the piercing makes contact with the electrode, he could be in (unintended and unsexy) excruciating pain!

If you play with e-stim, I highly recommend to wear isolating gloves when handling the eVac 2.0. Currency always takes the way of lowest resistance and thus the shortest way, so you should be fine. But there is a very small chance of currency passing through your heart when touching the rod with your bare fingers. So if you want to be extra safe (if you are not already into [heavy] rubber), wear insulating gloves.

Conclusion: Excellent vacuum cylinder with a naughty & nice e-stim twist.

Rebreathing Conversion Kit for Russion GP5 Gas Mask

Important Security Information

As hot and horny breath play is, NEVER DO IT ALONE OR BY YOURSELF! Every year we lose several members of the kink community to self-breathplay. No matter how much you think you have figured out the safety and falls backs, the is always a slight and sadly often lethal chance of it failing.

This especially applies to playing with inhalants like poppers or N2O/ laughing gas.

If you are curious about breath play, look for experienced partners to introduce you to this kink and its intricacies. Please just never do it alone!

According to the click numbers and reader questions, the VAST Breathing System is a very in demand toy for heavy gear kinksters and breath play enthusiasts. The issue with the system is that you need a face mask with separate ports for breathing in and breathing out. While this is easily done with anesthesia face masks, when it comes to gas masks, you were basically stuck with the AVON S10 or FM12 which due to Brexit are now hard to come by and are expensive (you can get a fully converted FM12 with a rubber head harness at VAST for 419€).

The Russian GP5 is probably the gas mask which most (rubber/ gear) kinkster start with. Millions were made between 1962 and 1990, the cold war brought them as far as East Germany. Because of this, the GP5 is so widely available and inexpensive that I struggle to name a kinkster who has not had one during their kink journey. But, due to their basic design with a – technically not, yet still compatible – GM40 thread for attaching a hose or filter and a simple oval back pressure valve, it could not be incorporated into the Breathing System or other BC systems. There was no way to create a closed breathing circuit. Until now.

Like all components of the Breathing System, a 3D printed unit does the trick. But unlike the conversion kit for the AVON gas masks, this one is very easy and quickly installed, without any injury risks.

First, you need to remove the membrane of the back pressure valve by simply gently pulling on it.

Then unscrew the two-piece closure from the main unit with the provided hex key. Be careful, the hex nuts are really small and fall out easily. Don’t do this over carpet! The unit comes with a spare one. But believe me, during the assembly process more then once a nut will fall out. So take care of the one you have – or buy an already upgraded GP-5 from VAST.

Next put the main unit which will split the air flow over the front of the GP-5.

Now first loosely screw the first part of the closure onto the main unit..

then the second part.

The manufacturing tolerance of the GP5 was very… liberal. So don’t expect the closure to perfectly fit. Because of that it is important to not tighten the screws directly tightly but gradually go around. Otherwise you will not be able to tighten it properly. A tight fit is vital to get it air-tight and use the GP5 for breath play!

After these few and easy steps, you have turned an artifact from the Cold War into a horny too for intense breath control! The top port is for breathing in, the bottom – also equipped with a back pressure valve – for breathing out. If you should forget which one is for which, they are labeled.

If the GP5 is not your style and your love the S10/FM12, VAST now also offer low-profile, right-angled GM40 hoses which look very hot and are quite convenient, especially in confined spaced.

ToyTorture’s Stocking Stuffer I – Small Latex Bags from VAST

Too often life happens while you make other planes. Enthused with ToyTorture.com being back up and finally looking functional and somewhat pretty in an oldschool minimalistic way again I planed to start new reviews in October. A bereavement in the closest family, cleaning out an apartment (not the anticipation fun filled clean out we usually talk about here…) and extreme workload at the daytime job which pays the bills and ultimately for this website forced me to abandon this plan. Not sure when reviews will return. Maybe in December, maybe in January or February. But, the Stocking Stuffer on the advent Sundays leading up to Christmas are a beloved tradition on ToyTorture.com that of course they will return this year!

The Three Sizes and some of the Colors of the VAST Phone Holster Bag made ouf of Latex

The Phone Holster suspended from a Latex Harness

End of September I visited VAST in Dortmund to give feedback on some toy designs. While waiting for the mastermind behind the Breathing System I strolled through the store and stumbled across these rubber holster bags. This design has been around in leather and most recently neoprene but I have never seen it executed in rubber!

This is a game changer for social events like the Pride parades, street fairs or bag nights. Most leather gear has some kind of pockets to store at least a few cards and a phone and even MX pants now come with pockets. But the sleek and smooth look of rubber does not really for carrying essentials around. So rubberists were either forced to mix materials or stuff their socks and suffer having a drowned phone from all the sweat running downwards. The VAST Holster Bags of a real useful and horny solution.

The Holster Bag attached to the Thigh using the two included Straps

The bags come in three sizes which all have the same internal size of 8cm width and 18cm heights which should be large enough for most phones. Depthwise you can choose between Medium with 2cm (enough for a phone, two or three cards and a bit of cash), Large at 3cm (enough space to also take the Folsom Europe booklet along or the diaper of an XL poppers bottle…) and XL which at 5cm is enough for a small camera or almost a small fisting kit if you use silicone lube. Being made out of finest rubber they are of course also the perfect breathing bag if you need a whiff of the delicious rubber latex scent.

The Back of the Holster Bag

You can attach the Holster either to a belt or harness using the hanger or turn it into a crossbody bag using the two included 64cm long straps. The straps are made out of VAST’s own aramide reinforced Superior Latex. They feature a D-ring each so are basically bondage belts. Of course they can be used to attach the bag to your thigh, upper arm or as a belt to secure it and keep it from dangling when being suspended from a harness. Speaking of security: The bag is closed with by a Loxx claps which is easy to open by pulling on the head. At first this is counter-intuitive and pulls on the bag. Thus you notice when somebody is fiddling with your belongings, making it extra secure at large events.

Both the medium and large Phone Holster Bag cost 149€, the XL 159€. They all come with a hanger and the two straps. VAST offers 9 standard colors of plain latex sheet. But they will happily make you a custom colored one to match your signature colors. On request VAST can also laser-engrave your personal logo into the bag to make it a real personal piece of gear.

Some of the Colors the VAST Cluth Bag comes in

Speaking of fashion, a little bit further into the start into the large selection of lady latex which covers the range from high fashion to hardcore kink over everyday attire – if you dare. An interesting way of bringing your kink into your daily life is through a clutch made out of VAST’s Superior Latex.

The almost Chanel Like Rhombus Patter of the Laser-Engraved Latex

It has the same great properties of the Holster bag, can withstand large force due to the aramid reinforced rubber, hates natural oils like all latex (be careful when carrying cosmetics inside!), is closed by a Loxx clasp and just smells delicious. Measuring W18xD3.5xH12.5cm in the inside it is large enough to hold a phone, keys, small wallet, tissues, a lipstick and even a pair of handcuffs. The should strap is attached to high quality stainless steel trim. It has a maximum length of 110cm and is detachable. Like the phone holster the clutch comes in 9 standard colors but can of course be custom ordered. The sleek latex version costs 159€. For an additionl 10€ you can get a version with a laser-engraved rhombus patter which gives the clutch a very upscale, almost Chanel-like appeal.

 

Head Harness for AVON Gas Masks

The VAST Head Harness for AVON Gas Masks in Red Superior Latex

Vendor: VAST

Happy Nikolaus Day! As promised last Sunday, here is a short bonus review of a an add-on for your AVON S10/ FM12 gas mask.

Construction

The head harness has the same six-point-shape of the original rubber (S10) or mesh (FM12) head harness of the AVON gas masks. The main difference is that you install roller buckles mounted on small latex straps using screw rivets into the clamp locks for adjusting the original head harness. The roller buckles come in plain or locking variety without a surcharge depending on your taste. Using these roller buckles you can adjust the main body of the head harness. The six straps attached to the back piece are quite long so they will fit even large heads. Since this head harness is one size fits all, on really small heads the access strap can flap around a bit. If you want to learn how to fit this head harness on your gas mask, I posted a little guide here (scroll down to the second half of the guide).

A Roller Buckle mounted onto an FM12’s Clamp Lock

Since VAST uses it’s own aramide reinforced Superior Latex for this head harness you cannot shorten the straps on your own. The good thing is because of the reinforcement you can really tighten or pull on it HARD. You will rather rip the locks off than then tear the rubber so don’t exert too much force.

Off the rack the harness comes in the “standard” fetish colors black, red and yellow. But I am sure you can ask for custom colors within the 4D Latex color scheme.

Playing with the Head Harness for AVON Gas Masks

For me this head harness is an innovative and breath-play suitable answer to the often asked question “Where can I a hood attached to my AVON gas mask?” A few years ago many rubber makers used to attach hoods to S10/ FM12 gas masks with a zipper at the back for a full rubber drone look. Currently I think only Blackstyle in Berlin and Regulation in London do this anymore if at all. Attaching a hood was often a not quite satisfactory thing because getting the fit right was difficult: Unlike a flexible rubber hood which wraps around the head, there is a big, stiff “front piece” which determined the fit of the rest of the hood. One result of this was that the actual gas mask did not create a full seal, making it unsuitable for breath play.

The Head Harness Attached to a Breathing System-ready FM12

With this head harness made out of latex you can create a hot looking, full rubber feeling yet still gas-tight configuration. For this put on your tight fitting latex hood as a base layer and then fetter the gas mask over it. This way your head is completely enveloped in rubber but the gas mask fits tight enough for proper breath play. Despite being aramide reinforced the rubber is soft so lying on the head harness is not uncomfortable. The rubber buckles are on the side so even the locks on the locking ones don’t press into your head when bound to the back.

The Back Piece with the Long Straps

The rubber base layer also keeps the head harness’ rubber from touching your skin and hair so you don’t need to clean it. Since oils and fats which are present on your skin and hair can destroy rubber over time, you need to clean latex after skin contact. Keep this in mind when using the head harness on bare skin.

Despite the wide range of adjustability I strongly recommend initially getting the right size gas mask size for your head! In order to work properly, the gas mask needs to create a tight seal around your face. Choosing a too large or too small gas mask will make this seal difficult, especially around the chin regardless how strong you tighten the straps.

Conclusion: Great feeling and highly functional alternative to attached rubber hood.

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 6th, 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.

How to Upgrade your FM12 to work with the VAST Breathing System

Important Security Information

As hot and horny breath play is, NEVER DO IT ALONE OR BY YOURSELF! Every year we lose several members of the kink community to self-breathplay. No matter how much you think you have figured out the safety and falls backs, the is always a slight and sadly often lethal chance of it failing.

This especially applies to playing with inhalants like poppers or N2O/ laughing gas.

If you are curious about breath play, look for experienced partners to introduce you to this kink and its intricacies. Please just never do it alone!

Ever since I introduced the VAST Breathing System here and showed the Upgrade Kit in the Unboxing, I was asked how to modify an existing AVON gas mask. It took my some time to secure another AVON gas mask because I did not want to mess with one of my old ones. For photo, play and collection purposes I wanted to keep them in their original state.

A couple of weeks ago I have bought an AVON FM12 at UK eBay and had a friend bring it over into the EU personally. I would not recommend shipping a gas mask from the UK into the EU because they can be considered armaments. This can get you into serious troubles.

In this article I show how to upgrade an FM12. But it should basically work the same way with an S10. For good measure I also show at the end how to switch the net to the VAST Head Harness made out of superior latex.

Please do not be puzzled if the pics sometimes show modifications I will explain later in the article. In the process I made some dumb decision and figured out that it would make sense to do other steps first. So the steps and pics now come in the best order in my opinion.

Important: In order to work with the VAST Breathing System – like with the Rebreather – there as to be a unidirectional airflow inside the mask.  So DON NOT REMOVE THE ONEWAY VALVE on the intake port! This is a major different to modifying your gas mask for directly attaching rebreathing bags!

You start with removing the cover of the air outtake.

Then remove the net from the back so you can easily access everything inside the mask.

Next, carefully take the drinking tube and then the respirator mask off.

On top of the air outtake unit runs a metal ring. Carefully remove this ring with the provided too. Be extremely careful because when you slip you can damage the rubber. Small dents close to the opening are not an issue because the hardware you will put in is a bit large and thus will cover the area.

Once you have removed the ring, you can now take the entire unit out.

Now you have to remove the speaking valve by removing the ring around it on the inside. This is best done with long-nose pliers. If you want retrofit your gas mask later, be careful not to damage the ring. I managed to break it. Again, be careful not to damage the rubber.

To prepare the gas mask for the mounting insert, warm the rubber around it with a hair dryer in order to make the material more flexible.

In order to fit the mounting insert, put the female thread through the front hole, hold the male threaded part at the back and turn the female part until it fits snuggly.

Repeat the same steps starting with heating the area around the hole for the exhalation valve. Make sure that the GM40 port is on the outside. This step is a bit cumbersome because it is quite cramped inside the mask. Now your AVON gas mask is ready for play with the VAST Breathing System – once you have attached the net at the back again.

Alternatively you can replace the net with the VAST’s Head Harness for AVON gas masks. It is made out of their aramid-reinforced Superior Latex and comes in standard and locking variety. For addition fail safe reasons, I chose the non-locking version.

To install the harness, thread the straps through the loops where usually the straps of the next go…

… and secure them using the screw-down rivets. Depending if you prefer a sleeker or more industrial look, put the recess on the inside or outside.

Now the FM12 is fully upgraded and ready to play.

How the additional components of the set perform and why Flashlight has labia instead ass lips is a story for another day and review.

Breathing System – Air Alteration Accessories

Example of the modularity and versitility of the VAST Breathing System

This is the third review on the ongoing serious in covering VAST extreme versatile (and thus complex) Breathing System. In the past I have covered the basic elements and took a detailed look at their Capsule Injector. Today I will review all different accessories which allow subsumed under altering the air stream.

If you want to get a quick overview of the Breathing System, take a look at my first and second unboxing. Recently I got my hands on a second FM12 so I soon will be able to show how to transform a gas mask using the Deluxe Upgrade Kit and Superior Latex Head Harness.

After that short orientation, let’s dive straight into it.

Switch (129€)

The name of this element is pretty telling: It is a switch between two air sources.

It looks like a small brother of the Rebreather. It has a diameter of 80mm and it 47mm tall like its big brother. It also features the same thick and easy to grab and to turn switch which tapers towards the end. The end points to one of two female GM40 ports. The port it points to is the port through which air goes in. The air will flow out through a female port on the opposite side of the Switch.

The Switch with the Inhaler & Breath Reducer Vario

The Switch is a useful, if not essential toy to play with the Air Alteration Accessories which I will review below. With just a turn you can switch between clean air or whatever flavoring device you are using. Or – as a top friend did – have two flavors of poppers ready. It is an extremely useful tool when you do multi-sub rebreathing (as one sub breathes the exhaled air of another). In this situation, getting fresh air into the system used to be very cumbersome. The switch makes it finally so easy that is it a relaxed scene.

If you want to integrate the Switch into your Breathing System setup, please only use short hoses! The longer the system, the more difficult it gets for the lungs to inhale fresh air. So in order to prevent unintended breathing issues, keep it short and tight!

Breath Reducer Vario (34.95€)

This a modern and multi-functional take on the tradition breath reducer with a simple hole. It is a 40mm short tube with a diameter just fitting into a female GM40 port. The lower third of the tube has a male GM40 thread so you can directly screw it into a gas mask or any air inlet of the breathing system. The top features five 6mm holes which are covered by an aligning disk with five 6mm holes. The rim of the disk is textured so it is easily turnable even with lubey hands or wearing thick gloves.

The Breath Reducer Vario Half Shut

When you turn the disk, the intersection of the holes and thus their diameter decreases and reducing the airflow. At about a third of a turn the air flow is noticeably reduced. Since there is seal between the disk and the top air can be sucked through the little gaps even when the holes are completely closed. But it is extremely difficult and strenuously. So the toy lives up to his name being a REDUCER and not a cut of. This is a failsafe because you cannot cut off the air permanently but forgetting to open it again. If you want to cut off the air flow completely, cover the disk with your palm. This way you are in direct contact close to the sub and can react directly if a situation is developing.

If the turning and gradual reducing of air flow is too distracting and thus sophisticated for you and you want the trusted and simple solution, VAST also offers a 6mm breath reducer for 22.95€.

Vaporizer with Switz

Vaporizer with Switch (169€)

The core of this toy is a switch tin with 80mm diameter and 47mm height like the other ones. In the middle there are GM40 female ports on each side. The rotary switch can point to two settings: Parallel to the ports is the “Pass”, turned about 30° down is “Vape”. When turned to Vape, the air flow is threaded through two 90° pipes which end in a lid. Onto this lid a 70mm diameter and 250ml volume can is a screwed.

The tin can be filled with poppers drenched cotton or whatever other aerosol emitting substance you want to expose your bottom to. The fumes can saturate the air trapped in the tin so once you turn the switch he is hit with a large quantity. If you want to reuse whatever you have put into the can, it comes with a screw-on cap to safe it for a later scene.

The Breath Reducer Vario on an AVON S10

The Vaporizer is a good element for extreme poppers pigs who want a strong, heavy rushing load. Through the easy to turn switch, dosing and turning off the poppers supply is easily and quickly done. Unlike other combinations (see below) it is a compact and integrated united. So especially when the high poppers does might impair you, it can be easily operated.

This is totally subjective but I love this element a lot! I like the bulky, heavy duty feel and look! It has a mad scientist vibe with the two kinked noticeable tubes from the switch to the screw lid. It just looks and feels heavy duty.

BUT: It does not make sense for everybody. The combination of a Switch with the Vaporizer or Inhaler (see below) is the more versatile solution. If you ONLY want to use poppers and NEVER would attach other accessories to the Switch, the Vaporizer with Switch makes sense. But if maybe want to have a scene in which you switch between a bubbler bottle and poppers, I would rather recommend the combo of the Switch with one of the two toys below. But if you are a toy nerd like me, you got to have both because you can create even more elaborate scene where you can switch between piss flavored and clean air and then can decide if poppers are induced or not.

(Popper) Inhaler

Inhaler (49.95€)

On top of the Inhaler sits a tube with a male GM40 thread on the outside to easily screw it directly into a gas mask or compatible accessory. On the next level below is a 10mm hole which leads to a 90° tube. This tube penetrates the lid and lets fresh air into the 100ml tin screwed onto the lit. The lid is also perforated with five round 50mm holes to let the whatever aerosol is trapped inside the tin stream upwards.

Topview of the Inhaler’s Lid

This is not only a great toy for any poppers pig who plays with gas masks. It is a great toy for every poppers pig! Drench (a few) cotton ball(s) with poppers, put them into the container and screw the top on. The bend tube and the five holes are small enough to trap most of the vapors inside. As soon as you start huffing with just your nose and mouth the agent escapes easily, flooding your lungs and mind. Especially in messy party situations or when you are clumsy like me so handling a bottle full of poppers can be dangerous, huffing safely from the Inhaler instead of an open bottle is so much handier. If you want to switch poppers brand throughout the night, a replacement tin with a lid costs 3.90€.

 

Bottom view of the Vaporizer’s Lid with it’s Tin on the Right

Vaporizer (79€)

The last of the three poppers inducing tools is the Vaporizer. It is a lid with two female GM40 ports on top. The lead to different holes in the lid so there are distinct in and out ports depending on the layout. The lid screws onto the same 70mm diameter 250ml plastic can like the Vaporizer with Switch. The can comes with a lid so you can store whatever is inside once the scene is done.

If you already have the Switch to alter between air and fumes and are playing with a HEAVY poppers pig, the Vaporizer is the way to go. Through the larger container about 2.5times more poppers fumes can collect than inside the Inhaler.

The Bubbler

The Vaporizer is a tool if your sub is into the permanent introduction of smells into the system. In this scenario put it directly before the air intake of the gas mask so the fumes hit him permanently. However, the nose quickly becomes desensitized to smells so the effect is limited. I would not recommend this with poppers because constantly breathing the vapors is not good for your heart and lung.

Bubbler (69€)

The Bubbler uses the same two female GM40 port design. The inlet is connected to 200mm long silicone tube which is closed with a plug at the bottom. In the bottom 4 rows of 5 holes have been punched inside the hose. The outlet is just a short 90° tube from the bottom of the lid. The head screws onto a 1l bottle. The thread fits many 1l milk bottles – at least in Germany. It even works with glass ones if you want to bring such material into your playroom.

The name of this toy comes from the effect it has: You fill it with a liquid – most commonly piss – till at least the highest of the holes inside the hose are covered. Once you start to breath, you have to create so long underpressure until the water level drops below the hole and the “vacuum” is broken. By doing this breathing is made harder because you first need to create sufficient underpressure (the higher the water column, the more underpressure is necessary). It also flavors the breathing air with whatever liquid is inside. In the process the liquid bubbles and thus the name.

The Bubbler’s Hose

This bubbler is a bit different from other bubblers I have played with. Usually a bubbler has a hose for letting air in. The immersion depth determines how difficult it is to get fresh air. Through this hose you can also add liquid if you are a meany. With this toy you have to decide how intense the scene is going to be by choosing the liquid levels. But to be frank, due to the small volume of the bottle and the highest hole being at about 40% of the way up, even in a full bottle drawing breaths is not getting so much harder. So this is rather a piss flavorer than breathing impairer.

Of course other bubblers have a hole in the top for the hose to go through. With the Vast Bubbler you can take the piss home with you in a replacement bottle. This will be extremely useful for pro doms!

When playing with this bubble, a bit of care is necessary. Due to the chunk, heavy-duty gas mask ports on top, it is extremely head-heavy. Add to this the small footprint of the bottle and it can easily tip over, causing the piss to flow everywhere. My recommendation is to put it in a lube bottle holder to store it safely.

Sniffer (119€)

The Siffer with the Two Jar Sizes

The Sniffer follows the same basic design of the Bubbler: Two female GM40 ports, one connected to 130mm hose, this time with only 4 holes in one of the 6 rows, one connected just by a hole through the lid and short 90° tube. The lid has a 100mm diameter and its thread fits large pickle jars 😉 The Sniffer comes with two PET bottles – or rather jars –, one with 1,250ml and one with 4,000ml.

As the name says, it is made for sniffing things, most often probably underwear or socks. Getting a jockstrap cup through the 100mm opening is a pain in the ass so I would not recommend it.

It is a good toy for inhaling the scents your top wants to expose you to if you stick to a few simple rules:

  • Don’t overpack. Fumes need spaces to waft. If you pack it to the brim, not only the hose will be kinked, shutting off the air, but the smell is packed instead of free flowing.
  • The warmer the medium, the better the smell. Often I get messages of frustrated sneaker and sox slave who have bought gear from one of their admired tops and the smell is rather faint. Body heat releases the smell so wear it for a couple of minutes before putting it inside. What I would NOT recommend is putting a warm grain pillow inside the jar! Those have a strong graining inherent smell and if you are not having a horse play scene it is really unsexy.

If you daisychain the Sniffer in a setup behind another fume agent – like a poppers source or the Bubbler bottle – be prepared for the content to take on the smell. Most often I used the Sniffer with really rank sox and the switch so the bottom was periodically exposed to heavy fumes and clean air. Since the sense of smell quickly gets used to smells, periodic break or switching between two strong smells for continuous intense effects is strongly recommended. But this toy also works if you want to prime your sub to your smell and let him breath only through the Sniffer. If you don’t pack it too densely (see above), you can comfortably breath through it so without the airflow being impaired. So the sub can sniff your smell indefinitely.

Again the (replacement) jars come with a lid so you can store whatever inside for the next scene.

Breathing System – Capsule Injector

Vendor: VAST

Important Security Information

As hot and horny breath play is, NEVER DO IT ALONE OR BY YOURSELF! Every year we lose several members of the kink community to self breath play. No matter how much you think you have figured out the safety and falls backs, there is always a slight and sadly often lethal chance of it failing.

This especially applies to playing with inhalants like poppers or N2O/ laughing gas.

If you are curious about breath play, look for experienced partners to introduce you to this kink and its intricacies. Please just never do it alone!

The VAST Breathing System Capsule Injector

After publishing my review of the Basis of the VAST Breathing System (link to review), I have gotten a couple of questions if the Capsule Injector also works with other breath play setups. In short, yes of course. For the long answer and because if you connect it directly to a gas mask you need to follow a little piece of advice, I decided give this toy a separate review.

Construction

The center of the Capsule Injector is a small 3D printed t-piece. On one side a 6l rubber breathing bag is attached, opposite of it a 50mm long gas mask hose ends in a GM40 port. Perpendicular to these things a black anodized aluminum cartridge holder for standard kitchen usage N2O cartridges is attached.

The Packaging of the Capsule Injector (comes without cartridges)

The toy comes in a beautiful heat-embossed wooden box outfitted with cut-out foam to house the toy. There are also holes for 24 cartridges so you can store them along the toy. Along with the toy itself comes a GM40 screw-on adaptor for attaching the Capsule Injector to 20mm professional breathing system tubes used in hospitals for example.

Playing with the Capsule Injector

Just by itself the Capsule Injector works as a standard 6l re-breathing bag. Of course this only works in a closed system in which you breathe in and out of the same port. Most gas masks have separate inlets and outlets which are sealed by back pressure valves. So in order to use a re-breathing bag, you need to modify them. For the most common gas mask types like the UDSSR GP-5 (commonly known as the “Russian gas mask”), AVON S10 or FM12 you can easily find guides online.

The GM40-to-20mm-Pro-Breathing-System-Adaptor

This closed-circuit breathing is also a necessity for N2O play. It gets absorbed quite slowly so it needs to rebreathed several times. Working with the capsules originally designed to power kitchen whipping siphons is usually a bit cumbersome. The Capsule Injector makes it very easy: You unscrew the bottom of the cartridge holder, put the cartridge in, screw it tightly and the gas gets released.

The Capsule Injector attached to a FM12 by a VAST Rebreather

If you are attaching the Capsule Injector directly to the gas mask or use a setup without a valve between the injector and the breathing mask, a word of warning: The pressure inside the capsule is quite high and once opened it will rush inside the bag, the tubes and also the breathing mask. This sudden increase in pressure can damage the lungs. So when popping the capsule, the bottoms mouth should be shut and he should be exhaling through his nose. This is not an optimal method but at least a bit safer. A slightly less expensive valve alternative to the VAST Rebreather (for example if you want to play with a modified Russian gas mask which currently does not work with the Rebreather) is the VAST Breathing Switch for 129€. With this you can simply switch between clean air and the Capsule Injector so all the capsule pressure goes into the bag from where it can be rebreathed safely.

A common point of criticism in the messages post the review was that the breathing bag is firmly connected to the cartridge holder instead of using a GM40 port. That way the 6l rebreathing bag could be exchanged for a smaller rebreathing bag. The 6l bag is actually necessary because one N2O capsule holds about 6l of gas. Smaller volumes would increase the pressure inside the system (see above). So when playing with N2O you are kind of stuck with 6l. If you want smaller bags, you have to pre-fill them externally where the access gas can escape before attaching the bag to the setup directly which again is a cumbersome process.

Conclusion: Innovative special purpose restraint with practical shortcoming.
