Review · Torso massager · TPE, 8,5 kg
Hidden Desires torso massager weighing 8.5 kg reviewed against the manufacturer’s own specifications. Two tunnels with different characteristics, ten vibration modes, and a rechargeable lithium-ion battery — but only IPX5, porous TPE, and a datasheet where runtime, charging time, insertion depth, and sound level are missing, even though the same manufacturer publishes them for the sister models.
One of the cheapest ways into the category of torso massagers, and the weight of 8.5 kilos makes it do exactly what it’s supposed to: the product stays put without being held in place. The manufacturer lists ten vibration modes, two tunnels with different character, and a rechargeable lithium-ion battery. What lowers the rating isn’t the product—it’s the base material instead: TPE instead of silicone, IPX5 instead of submersible, and a datasheet where operating time, charging time, insertion depth, sound level, and warranty are all missing, even though the same manufacturer publishes them for sister models in the same series.
Fuck My Horny Vibrating Cunt 8.5 kg is a torso masturbator from the Bangers series, which Hidden Desire sells via the Dutch wholesaler Scala. So it is not a handheld loose vagina, but a molded lower body with two separate tunnels — a vaginal and an anal — and built-in vibration. The manufacturer states the product dimensions as 26 × 31 × 21 centimeters, the material TPE, ten vibration modes, a rechargeable lithium-ion battery, and the enclosure rating IPX5, which the manufacturer itself translates as the word "Splashproof".
The weight of 8.5 kilograms is in the product name and on the packaging, where the manufacturer prints it as "8.5 kg. of fuckable pussy & ass". It’s the single most important number in the entire specification, and it explains both what the product can do and what it costs in practical hassle. The weight isn’t a side effect of the size — it’s the function itself, because that’s what makes the product stay put against a surface instead of having to be held in place.
This review is exclusively about the item with EAN 8713221841292, the manufacturer’s item number 16939-SKIN, and model number 16939, in the only color variant the manufacturer lists: Light Skin Tone. The number is checked directly against the manufacturer’s variant data, and all five stores that sell the item list the same EAN. It’s needed, because Hidden Desire sells a couple dozen torso models in parallel under similar-sounding names, and several of them weigh exactly the same amount.
In this market, no shop in our data sells the product.
The product class lies between two things that most people know. A regular pocket pussy or a Fleshlight weighs a few hundred grams, is held in the hand, and moves with the motion. A sex doll in full size weighs twenty kilos or more and is, in practice, a piece of furniture. A torso is the middle step: a molded lower body without a head, arms, and lower legs—heavy enough to withstand movement but small enough to be carried out of the way.
The manufacturer’s size specification says what it means here. 26 × 31 × 21 centimeters is roughly the volume of a large travel-cube, and 8.5 kilograms is in the same range as a well-packed carry-on bag. What can be established is that it is neither manageable with one hand nor impossible to move—it is exactly heavy enough to require a place to stand on and a place to be stored, and both of those things have to be solved before you order.
The manufacturer describes the construction as a vibrating vagina and butt with structured channels, molded in what they call Realistic Love Skin. In the manufacturer’s own cross-section graphic, the two tunnels are named separately: the vaginal one as “stretchy & velvety smooth” and the anal one as “super tight & textured.” So they are intentionally different, which is the most important difference compared to a simple pocket pussy with just one opening.
The name of this product is not consistent, and it’s worth knowing before you compare listings. The manufacturer calls it Fuck My Horny Cunt 8.5 kg, without the word “Vibrating.” Some listings call it Fuck My Horny Vibrating Cunt 8,5 kg. Others call it Hidden Desire: Bangers, Fuck My Horny Cunt, 8.5 kg, and some call it Fuck My Horny Cunt 8.5 Kg Skin.
All five are the same item. You can determine it without a doubt, because all stores list EAN 8713221841292, and that number is the same as the one the manufacturer has linked to item 16939-SKIN. The addition “Skin” with one listing is the color variant Light Skin Tone, which is the only one that exists. The addition “Vibrating” in other listings is accurate as a description but not the manufacturer’s own name.
Why it matters: Hidden Desire has multiple models in the same series that differ specifically in vibration. Round Ass Bimbo 8,5 kg (EAN 8713221820754, also sold as Fat Ass Bimbo) weighs exactly the same, but the manufacturer does not list any vibrating function at all for that model—only dimensions, material, and insertion depth. So when you search for “8,5 kg” and a price, you get hits for two completely different products. It’s the EAN number that distinguishes them—not the name and not the weight.
The material question determines more than anything else how long an intimate product stays hygienic, and here is the answer clearly from the manufacturer and messy on the retailers’ side. Hidden Desire’s specification lists just a single material: TPE. The marketing name Realistic Love Skin, which appears in all the store texts, is the manufacturer’s designation for that exact TPE blend—one retailer spells out the connection outright and describes Realistic Love Skin as a silky, flexible TPE material.
One store says otherwise. Another store lists the material as “High-quality silicone” in its product data. That information stands alone against the manufacturer’s specification, against other retailers’ material listings, and against other quick facts, both of which state that it is TPE. When a store contradicts the manufacturer, the manufacturer wins, and that’s the case here: the product is TPE, not silicone. The difference isn’t cosmetic, which the next section is about, and anyone who chooses a product based on that store’s material line is choosing on the wrong substrate.
TPE stands for thermoplastic elastomer. It’s a group of materials that behaves like rubber but can be melted and reshaped like plastic—which is exactly why large cast bodies are made in TPE and not in silicone: the material is cheaper, it can be cast in large volumes, and it gets a soft, yielding feel that sits close to skin. For a torso masturbator, that’s a reasonable technical compromise—a corresponding body in platinum silicone would cost several times as much.
You pay for hygiene. TPE is a porous material. The surface has microscopic cavities where moisture, lubricant, and body fluids can remain, and those cavities can’t be rinsed clean in the way a non-porous silicone surface can. Silicone is non-porous, tolerates boiling, and can in practice be sterilized. TPE can neither be boiled nor sterilized without the material being damaged.
The consequence is practical and concrete. A TPE product has a limited service life even when it’s cared for perfectly, and it must dry properly inside after every use to avoid becoming a breeding ground. On a product with two blind tunnels that can’t be turned inside out—which is the case here, since the tunnels are cast into an 8.5-kilo heavy body—it’s the most difficult part of maintenance. It’s not an argument against the product itself; it’s an argument for knowing what you’re buying.
Two more TPE properties belong in the decision. The material is sensitive to silicone-based lubricants, which break down the surface. And TPE can react with other soft plastic during long-term storage, which is why products in this material should never be kept with skin-on-skin contact with other toys in the same drawer.
Phthalates are a group of plasticizers used to make plastic flexible. The Kemikalieinspektionen (Swedish Chemicals Agency) describes them as substances that can affect the endocrine system and make reproduction more difficult, and several of them are restricted or banned within the EU in a large number of product types. This particular product category is repeatedly the subject of supervision, because it consists of plasticized plastic against the mucous membrane in large quantities.
Here, something has to be said that isn’t comfortable but is true: Hidden Desire does not publish a phthalate declaration for this article. The specification states “TPE” and nothing more—no information that the material is phthalate-free, no information about which plasticizers are included, and no reference to any material standard. None of the stores listed here publishes such information either for this exact article.
It’s worth putting it in context. TPE is not the same as plasticized PVC, and the most common types of TPE do not require phthalate plasticizers to become soft. So the absence of a declaration is not evidence that the product contains phthalates. But it’s also not evidence of the opposite, and for a product that weighs 8.5 kilos and consists mostly of exactly that material, it’s a piece of information that you reasonably should be able to get. Where other manufacturers in the category print an explicit material declaration on each product page, here you only get three letters.
The manufacturer lists the product dimensions as 26 × 31 × 21 centimeters, and the same three numbers are shown on the manufacturer’s own cross-section graphic: 26 cm in length, 31 cm in width, and 21 cm in height. Joylands spectabell reproduces exactly the same figures, broken down into length, width, and height. It’s unusual for a store and a manufacturer to match down to the millimeter in this category, and here they do.
The weight, however, is two different numbers, and the difference is simple to explain. 8,5 kilo appears in the product name and on the packaging and refers to the product. 10,5 kilo is the manufacturer’s “weight per unit” in the logistics information, and the same number is listed as shipping weight in the manufacturer’s product data. The two kilos in between are the cardboard box, which the manufacturer gives as 36,5 × 36 × 24,5 centimeters. One of the shops lists the product weight as 8 500 grams, which confirms the packaging figure.
The practical thing to take away is that the package that arrives at your home is a cardboard box that’s almost four decimeters in two directions and just over ten kilos. It’s not a mailbox package, and it’s not something you discreetly carry home from a pickup point with one hand. The manufacturer also states that each cardboard box contains one unit, which means that the packaging is the retail packaging—so what you see in the store’s flow is what gets delivered.
What the manufacturer does not state for this model is the insertion depth. For the sister model Round Ass Bimbo 8.5 kg, both the overall length and the insertion depth are published—vagina 17 centimeters, anal 13 centimeters—and for Horny Milking Bitch 10 kg, the insertion depth is given as 10 centimeters. For 16939, nothing is stated. Tunnel lengths are not published by the manufacturer, and none of the five stores fills the gap. It’s a real shortcoming in a product where the tunnel length specifically determines whether it suits the user.
The color is the only one available: the manufacturer lists a single variant, Light Skin Tone. Some retailer listings describe it as "ljus hudfärg", others call it "Nude", and one includes "Skin" in the product name. So there’s no color choice to make, and no risk of ordering the wrong variant.
The electronics are simple, and the manufacturer describes it briefly. The specification lists ten vibration modes and a rechargeable lithium-ion battery. The product description says that you start the product by pressing the button and then selecting your favorite mode. One shop clarifies where the button sits: the function is controlled via a button at the back. The manufacturer’s own product images also show a round control panel recessed into the back of the product, which matches the shop information.
There is no remote control, no app, and no Bluetooth in the specification. This isn’t a drawback but a consequence of the product type—the control sits on a body that weighs 8.5 kilos and stays in place, so the distance to the button is always the same. What can be established is that the interface is a single button that steps between ten modes, which means you pass through nine modes to get back to the first.
The specification table lists ten vibration modes. The packaging states ten vibration modes, printed in a gold marking on the front. But the manufacturer’s own cutaway graphic for the same item is labeled "5 Vibrating Modes".
Two out of three pieces of information in the manufacturer’s materials say ten, and they’re also the two that are product-specific: the spec table and the printed packaging. The cutaway graphic is an illustration of the same type that appears on several models in the Bangers series, and the most likely explanation is that it was reused without updating the number. But that’s an interpretation, not a fact, and the interpretation should be presented as such.
The graphic contains information that isn’t shown anywhere else, and that is worth reading. It shows two separate vibrating units, one placed at each tunnel, instead of a single motor that shakes the whole body. That’s the technically interesting detail: an 8.5 kilo heavy TPE body dampens vibration extremely effectively, and placing the motors directly at the tunnels is the only design that makes the vibration reach the place it’s supposed to. If the graphic’s “5 Vibrating Modes” were meant to refer to five settings per unit, then ten and five would go together — but the manufacturer doesn’t claim that, and therefore it amounts to nothing more than a possibility.
The manufacturer’s cross-section graphic names the tunnels individually, and the descriptions are different in a way that matters. The vaginal tunnel is described as “stretchy & velvety smooth” — stretchable and smooth. The anal is described as “super tight & textured” — tighter and structured. The graphic also shows that the structure differs: the anal canal is drawn with clearer ribs.
One listing adds a third description of the same thing in its spectabell, where the surface is stated as bumpy, ridged and silky, the openings as anal and vagina, and the hardness as soft. Another shop lists the elasticity as “stretchy”. The three store details point in the same direction as the manufacturer’s graphic, which is about as close as you can get to a confirmation of a feature that no one measures in numbers.
So what’s missing isn’t the description, but the measurement. None of the sources states how deep the tunnels are, how wide they are, or how much they stretch. Since the manufacturer publishes those exact figures for two other models in the same series, this is a deliberate omission rather than a general practice, and it’s reasonable to expect that the insert depth is shorter than on the larger models — a total length of 26 centimeters sets a physical limit that no tunnel can exceed.
The manufacturer publishes no decibel value for this model, either on the product page, on the packaging, or in any graphics. None of the stores listed here provides any measurement either. Anyone who sees a decibel number for the product on some other site should assume that it lacks a source.
Not having that information is particularly worth noting here, since the manufacturer publishes it for a sister model. On Horny Milking Bitch 10 kg, the sound level is written as 60 dB in the same spectabells format. Hidden Desire therefore has both the format and the habit of reporting sound level — it just hasn’t done it for 16939.
The only thing that can be established on a general level is that a large TPE body functions as a sound dampener. The mass absorbs vibrations instead of amplifying them, which is the opposite of a small hard plastic product that easily turns into a resonance box. On the other hand, that same mass can transfer vibrations to the surface underneath, and then the same advice applies as for all vibrating products: a soft surface dampens, a hard tabletop amplifies.
The manufacturer states the enclosure class IPX5 and writes the translation "Splashproof" itself. The rating comes from the international standard IEC 60529, which defines enclosure classes for electrical equipment. The number 5 in the second position means that the product has been tested against water jets from a nozzle from any direction—so more than splashes, but expressly not submersion.
The stores describe the same thing, and they do it correctly. One shop lists the water resistance as "splash-resistant". Another writes "only splash-proof". None of them claims that the product is waterproof, and that is correct: it isn’t.
The difference between IPX5 and IPX7 is greater than a single-digit step suggests, and for this particular product it’s the deciding factor. IPX7 means, according to IEC 60529, that the product can handle submersion to a depth of one meter for 30 minutes. IPX5 means that it can handle a water jet, but says nothing at all about submersion. The classes are not cumulative in the way you might intuitively think.
The consequence is concrete: the product can be rinsed off, but it can’t be placed in the bathtub, in a tub, or in a bucket. That’s a problem here, because an 8.5-kilo body with two blind tunnels is precisely the kind of product you would most want to dip. Cleaning the inside of two molded channels under running water without wetting the electronics requires careful consideration, and it’s the most time-consuming part of owning a product like this.
The contrast with the sister models is striking. Horny Milking Bitch 10 kg is listed by the same manufacturer as IPX7 Waterproof, and Big Bubble Butt 8 kg is simply listed as "Waterproof". So within the same brand and the same price category, there are models that can be submerged. This one can’t—and it’s the single most important care difference between them.
Rinse both channels with lukewarm water after every use and use an unperfumed soap or a cleaning product intended for intimate products. Keep the product so that the water runs out through the channels instead of toward the electronics on the back. Let it dry completely inside before putting it away — TPE is porous, and moisture that remains in a blind channel is the most common cause of this type of product developing an odor that can’t be washed away.
Lubricant is mandatory rather than optional for TPE, and it must be water-based. One listing explicitly states water-based as the recommended lubricant for the item. Silicone-based lubricant attacks soft elastomer surfaces and makes them sticky and porous over time, and oil-based products like coconut oil leave a film that is almost impossible to remove from a channel you can’t reach. Expect to use significantly more lubricant than with a handheld product, because the tunnels are long and absorb liquid.
Many owners of TPE products dust the surface with cornstarch or talk-free toy powder after drying to prevent the material from becoming sticky. It is not an instruction from the manufacturer — Hidden Desire publishes no care instructions for the item at all, and no shop in our data does either. Store the product dry, in the dark, and without direct contact with other soft plastic, and avoid heat. That it must not be boiled follows from the material; that it must not be submerged follows from IPX5.
The manufacturer lists two things about the power supply: that the product is rechargeable and that the battery is of the lithium-ion type. That’s it. Some shop listings specify “rechargeable via USB” and list the charging type as “USB”, but both are shop details, and none of them says which connector is used.
Via USB, according to one listing. Which connector type is on the product — USB-C, micro-USB, or a magnetic charging puck — isn’t shown in any of the sources available. It also isn’t clear whether a charging cable is included, which is a glaring omission: the manufacturer publishes no packaging contents list at all.
The question isn’t academic. On an IPX5-rated product, the charging connector has to sit behind some kind of protection, and the person charging a body that weighs 8.5 kilos also needs to know whether the cable is long enough to reach the floor or whether the product is meant to be placed on a table. Assume you’ll need to check that with the shop before ordering if it matters to you.
Hidden Desire does not publish operating time, charging time, or battery capacity in mAh for this article. Nor does any listing provide additional information. That means it isn’t possible to say how long the product runs on a single charge, and it means that anyone who wants to calculate the battery’s load or lifespan has nothing to go by.
What makes the omission noteworthy is that the manufacturer publishes exactly those same figures for other models in the same series. For Horny Milking Bitch 10 kg, the runtime is listed as 90 minutes and the charging time as 150 minutes, in the same spec table and in the same format as used here. The field is therefore in the manufacturer’s system—it’s just blank for 16939. A reasonable interpretation is that the information wasn’t submitted rather than that it’s meant to be secret, but the result for the buyer is the same.
What applies generally to lithium-ion batteries also applies here. Capacity drops with the number of charge cycles; the cell does best when it’s charged regularly instead of being stored fully discharged; and it’s very likely that it can’t be replaced in a molded TPE body. Practically, this means that the electronics, not the material, likely set the limit for how long the product works as a vibrating product—and that afterward it still works as a non-vibrating torso, which is actually a comfort that doesn’t apply to most other toys.
We do not have price data from shops in your market yet.
The manufacturer publishes run time, charging time, insertion depth, and sound level for the system model. For this item, the fields are left blank.
The most relevant comparisons are within the same brand, because Hidden Desire sells around twenty torso models in parallel, and because several of them are sold by the same stores. All specifications below come from the manufacturer’s own product pages.
Big Bubble Butt 8 kg (EAN 8713221820297) makes for the sharpest comparison there is.
The differences are somewhere else. Big Bubble Butt measures 37 × 36 × 13 centimeters versus our 26 × 31 × 21—so it’s wider and longer but significantly flatter, which is a different shape rather than a different size. The material is listed as Realistic Love-Skin TPR instead of TPE. And the most important difference: Big Bubble Butt is powered by AAA batteries and is listed as waterproof, while Fuck My Horny Vibrating Cunt has a rechargeable lithium-ion battery and only IPX5.
It’s a real trade-off. AAA batteries mean the power supply is never used up—you replace the batteries—but you also have to have batteries at home, and the battery compartment cover is a weak point. Li-ion means convenience right now and a dead product later. That the simpler model is also the one that can be submerged in water is unexpected, and for anyone who prioritizes cleaning over charging convenience, it points toward Big Bubble Butts.
Horny Milking Bitch 10 kg (EAN 8713221842305) is the model where the manufacturer actually lists everything: dimensions 40 × 29 × 22 centimeters, total length 40 centimeters, insertion depth 10 centimeters, material Realistic Love Skin TPR, operating time 90 minutes, charging time 150 minutes, enclosure rating IPX7 (Waterproof), seven milking modes, sound level 60 dB, and a li-ion battery.
It’s an instructive comparison of a reason that goes beyond the products themselves. It shows that the lack of operating time, charging time, insertion depth, and sound level on 16939 isn’t the brand’s policy—it’s a gap in just that article’s datasheet. Same manufacturer, same series, same spectabells format, and there it all is.
Functionally, the two products are different. Horny Milking Bitch works with milking modes rather than pure vibration modes; it’s heavier and longer, and it can be submerged in water. If you want a torso where you know what you’re getting, and you can add the thousand-krone bill, it’s a more transparent purchase. If you want two tunnels with different character and the lowest possible entry in the category, 16939 is the cheaper route.
Juicy Sucking Pussy 4 kg (EAN 8713221841285) The manufacturer lists the dimensions as 19 × 27 × 16 centimeters, the material as TPE, rechargeable operation, IPX5 (Splashproof), a li-ion battery— and both ten vibration modes and five sucking modes.
So it’s the same material, the same enclosure rating, the same battery type, and the same number of vibration modes, plus a suction function that 16939 lacks, for a lower price. What you lose is the mass. 4 kilos versus 8.5 kilos is the difference between a product that needs to be held or supported and one that just sits there on its own, and 19 × 27 × 16 centimeters is a noticeably smaller body.
The conclusion is more straightforward than you might expect: if you’re buying for the sake of the features, Juicy Sucking Pussy is the better buy, because it has more of them and costs less. If you’re buying for weight and the body, it’s not a replacement at all. 8.5 kilos is the whole point of this product, and it’s the only thing the sister model doesn’t have.
Round Ass Bimbo 8.5 kg (EAN 8713221820754) Weighs exactly the same. The manufacturer states the dimensions as 37 × 36 × 25 centimeters, with a total length of 37 centimeters and an insertion depth of 17 centimeters vaginally and 13 centimeters anally, in TPE material. No vibration, no battery, and no ingress protection rating are specified for the model.
The comparison is worth making for two reasons. The first is that it shows how much larger an 8.5 kilogram body can be with a different design — 37 × 36 × 25 versus 26 × 31 × 21 centimeters is a noticeably larger product at the same weight, which means that our model is more compact and denser. The second is that it publishes the insertion depths that are missing on 16939, and thereby provides an indication of what a Bangers torso in this weight class usually offers.
In this market (EU/EEA), no shop in our data sells it.
The spread is partly explained by campaign prices. What you pay for, in this case, is nothing other than the store’s margin, since the item is identical.
Our store checks indicate a favorable stock situation. The product was available in multiple stores at the time of our price check. Inventory levels for a product that weighs ten kilos in cardboard are rarely deep at online stores.
A practical note about shipping. In this weight range, several stores’ threshold for free shipping is below the product’s price—shipping for a ten-kilo package isn’t always included in the standard offer. Always check the final total at checkout before comparing the stores with each other—shipping fees can reduce the difference between offers.
It’s a good fit for you if you specifically want weight. 8.5 kilos is the difference between a product you have to hold in place and one that stays put by itself, and that feature can’t be achieved for cheaper or in a smaller format. It’s a good fit for you if you want two openings with different character in the same product, because the manufacturer has expressly made the anal tunnel narrower and more structured than the vaginal tunnel. And it’s a good fit for you if you want to get into the category of torso masturbators.
It’s not a good fit for you if you prioritize hygiene above everything else. TPE is porous, the tunnels are blind, the product must not be submerged in water, and the manufacturer publishes neither a phthalate declaration nor care instructions. It’s not a good fit for you who wants to know what you’re buying before you buy it: runtime, charging time, battery capacity, insertion depth, sound level, charging connector, and what’s in the package are all missing from the manufacturer’s datasheet. And it’s not a good fit for you if you have limited storage space—the cardboard box is 36.5 × 36 × 24.5 centimeters and the product can’t be put into a dresser drawer.
One last thing belongs in the decision. If you want the same brand and the option to rinse the entire product, Big Bubble Butt 8 kg is described with the Waterproof enclosure rating. If you want a complete specification, Horny Milking Bitch 10 kg provides a full specification. Choosing 16939 is therefore an active choice of shape and weight over both reporting and ease of cleaning, and that choice should be made deliberately.
Hidden Desire does not publish any manufacturer warranty for this item. Neither the product page nor the brand page lists any warranty period, and none of the five stores show any voluntary warranty from the manufacturer. The manufacturer also publishes no warranty information for any of the four sister models compared in this review—so this isn’t just a missing piece in this datasheet; it’s a consistent trait of the brand.
What applies instead is your statutory rights, and they always apply. Under EU rules, the seller is liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee). So the fact that the manufacturer is silent about warranty doesn’t mean you’re left without protection—it only means you don’t get anything beyond the law.
For distance purchases in the EU and EEA, you generally have a 14-day right of withdrawal, starting when the goods are received. Under EU rules, sealed goods that are not suitable for return for health or hygiene reasons are exempt from the right of withdrawal once unsealed, and this type of product almost always falls under that exception. However, the right to complain about defects always applies: in the EU, the seller is liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee).
A final piece of advice that follows from the weight: check the package before you pick it up. A molded TPE body weighing 8,5 kilo takes transport damage in the form of pressure marks, and such marks are easier to make a complaint about right away than after the packaging has been opened and thrown away.
