Hidden Desire Big Bubble Butt 8kg: review

Hidden Desire Big Bubble Butt at a glance — eight kilos in doggystyle

Hidden Desire Big Bubble Butt is a so-called torso masturbator: a cast lower body without arms, legs, or a head, with two penetrable channels and a weight that is intended to keep the product in place by itself. The manufacturer is Hidden Desire, the product is part of the Bangers by Hidden Desire series, and the full name in the manufacturer’s own assortment is Big Bubble Butt Bitch Vibrating. In Swedish stores, it is sold under at least six different names, which is the first thing this review needs to clarify.

The specification that the manufacturer publishes is short but unambiguous: dimensions 37 × 36 × 13 centimeters, weight approximately 8 kilograms — the manufacturer itself states it as 18 pounds — material listed as Realistic Love-Skin and TPR, waterproof, body-safe, powered via AAA batteries and batteries not included. The packaging also states two vibrating bullets and that the product stands firmly on any surface. The color is called Light Skin Tone and it is the only one the manufacturer offers. The price in Sweden is between 1,526 and 2,998 SEK.

This review is about the item with EAN 8713221820297, the manufacturer’s item number 17040-SKIN. The number is checked directly against the manufacturer’s own item entry, where the barcode is on precisely that variant. Seven Swedish stores list the same number. What makes the check worth the trouble in this case is that the item is one of the most rebranded products in the entire category.

Big Bubble Butt, Bubble Butt Bitch, or Bangers — the same item?

Yes. Same EAN, same item number 17040, same dimensions. Here’s what it’s called in the stores that sell it: Joyland calls it "Hidden Desire: Bangers, Big Bubble Butt Bitch Vibration", Blush Me calls it "Hidden Desire Big Bubble Butt 8kg Sexdoll", SexleksakerOutlet calls it "Hidden Desire Big Bubble Butt 8kg", Vuxenkul calls it "Big Bubble Butt Bitch Vibr", Taboo calls it "Big Bubble Butt Masturbator", and Lekosmek simply calls it "Bangers Stor Masturbator". Taboo also lists the brand as Scala, Lekosmek as Bangers, and the others as Hidden Desire — three different brand names for the same item.

There is a fourth variant on the theme, and it is more interesting than the others. Sexonic lists the barcode 8713221820297 twice in the same store: once as "Hidden Desire Big Bubble Butt Bitch Vibrating Skin" with the store’s item number 2076, and once as "ACT — Bubble Butt Real Stico Masturbator with Vibration" with the item number 21306. The price is identical in both listings. This points to the item having received a new brand name somewhere in the distribution chain, and that the store has posted it again without removing the old entry. Practical consequence: two search results that look like two products are actually a single item, and a price comparison that treats them as two is wrong.

Checking the barcode instead of the name is therefore not a formality here. It is the only way to know that you’re comparing the right things, because Hidden Desires Bangers series includes multiple products that are described with almost identical words—Nasty Nympho Bouncer, Slutty Tight Cunt, Screw Me 15kg, and Big Ass Milking Bitch 16kg are all separate items with their own EAN numbers.

What a torso masturbator is, and what the eight kilos do

The difference between this product category and a normal inflatable vagina lies almost entirely in the weight. A handheld masturbator weighs a few hundred grams, and you control all movement yourself. An eight-kilo torso stands still when loaded, and that is the whole point of the design: the manufacturer’s packaging presents it as a product that stands on any surface for use without hands.

What can be established purely physically is that friction against the surface increases with weight. Eight kilos spread over an area of 37 × 36 centimeters provide enough gravitational force for the product to stay in place during movement—something a product weighing a couple of hundred grams does not do. That is also why the manufacturer and the stores consistently describe it as intended for a position from behind—the shape is molded for that stance, and the angle of the channels follows from it.

The back side of the same coin is just as concrete. Eight kilos is roughly the weight of four full milk cartons, and that weight has to be carried to the bathroom every time the product is cleaned, lifted back again, and then stored somewhere where it neither collects dust nor is visible. The dimensions 37 × 36 × 13 centimeters mean that it doesn’t fit in a toiletry bag, a drawer, or a bedside table. It requires its own space, and that is the single most important practical question to ask yourself before buying—before the material, before the price, and before the vibration.

Material: TPR, TPE, and the contradiction in the manufacturer’s own text

The material question is the only property of an intimate product that can’t be compensated for by habit or care, and here there is a discrepancy that’s worth taking seriously. The manufacturer’s specifications list states that the material is "Realistic Love-Skin | TPR". Two lines higher up on the same product page, it instead says that the product is made of TPE of good quality. The manufacturer therefore contradicts itself within the scope of the same page.

Since then, the stores have chosen a side as they see fit. Joyland, Taboo, and Lekosmek state TPR. Blush Me states "skin-friendly TPE", SexleksakerOutlet writes "phthalate-free, body-safe TPE quality", and Vuxenkul writes "high-quality TPE". It’s therefore a fairly even split, and none of the stores can be said to be wrong—they’ve read different parts of the same manufacturer text. When a store contradicts the manufacturer, the manufacturer wins, but here the manufacturer contradicts itself, and then the information remains unclear.

What’s the difference between TPR and TPE?

Less than the names suggest, and that’s probably the explanation for the sloppiness. TPE stands for thermoplastic elastomer and is an umbrella term for an entire family of materials that behave like rubber but can be melted and re-molded like plastic. TPR stands for thermoplastic rubber compound and is, in practice, a subgroup within the same family. In the sex toy industry, the labels are used almost interchangeably, and both describe soft, moldable materials that can mimic skin.

What’s common to the entire family, however, is crucial—and it applies regardless of which of the two letter combinations is correct: TPE and TPR are porous materials. The surface contains microscopic cavities that can’t be rinsed clean in the same way as a non-porous surface. Silicone, which is standard in the premium segment, is non-porous and can therefore be cleaned properly again and again. A porous material can be cleaned—but never sterilized—and residues that end up in the pores remain there. That’s the fundamental difference between this product and a silicone product, and that difference doesn’t show on the price tag.

The practical consequence is that the product has a limited service life determined by the material rather than by the mechanics. Over time, a porous material becomes sticky and absorbs odors, and once that has happened, it can’t be remedied. That’s why both Lekosmek and several other stores recommend renewal powder—see the care section further down.

Phthalates and "body-safe"—what the declaration covers

Phthalates are a group of softeners used to make plastic—above all, soft PVC—flexible. The Swedish Chemicals Agency (Kemikalieinspektionen) describes them as substances that can affect the endocrine (hormone) system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU in a large number of products. This particular product category is the subject of ongoing oversight, because it is based on soft plastic that lies against the mucous membrane.

What does the manufacturer say? Exactly one word: "Bodysafe: Yes". That’s the whole declaration. The manufacturer does not publish an explicit statement that the material is free from phthalates, does not publish a material composition other than the designation TPR and TPE respectively, and publishes no test certificate. Two Swedish retailers—Blush Me and SexleksakerOutlet—go further than the manufacturer and write that the product is phthalate-free. That means it is a retailer claim, not a manufacturer claim, and it should be read accordingly.

That the difference matters is easy to show. “Bodysafe” is not a defined concept and not a certificate—it’s a marketing term. That a product is sold legally within the EU means, of course, that it must comply with chemical legislation, but that is a completely different matter than a published material declaration. Anyone who wants an unambiguous answer about softeners will not get one here, and that is a reasonable reason to choose not to buy the product if the material issue is important to you.

Measurements 37 × 36 × 13 cm—and the weight that isn’t quite eight kilos

The measurements are the only value in the entire specification that all sources agree on. The manufacturer states 37 × 36 × 13 centimeters, corresponding to 14.2 × 14.5 × 5.9 inches, and Joyland, Taboo, Blush Me, SexleksakerOutlet, and Lekosmek repeat the same three numbers. That makes the measurement information the most reliable line in the table.

The weight is a different story, and it deserves a note. The manufacturer’s product text says "approximately 8 kilos (18 pounds)"—so explicitly an approximate value. The manufacturer’s own packaging says "almost 8kg", meaning just under eight kilos. Taboo lists 8 600 grams in its specification table, i.e., a little over eight kilos. And Joyland gives about 8 kilos in its bullet list but about 8.5 kilos in the body text on the same page.

What can be established is that none of the sources state an exact product weight, that the manufacturer itself reserves the wording twice with the words "approximately" and "almost", and that the range in published information runs from just under 8 to 8.6 kilograms. The difference of half a kilo has no practical significance for how the product behaves, but it says something about how specific the specification is compiled: eight kilograms is a marketing figure, not a weighed value. That the stores then build the product name on that exact number — "Big Bubble Butt 8kg" — does not make the figure any more precise.

One more thing about the packaging, which Blush Me and SexleksakerOutlet are the only ones to state: because of its size and weight, the product is not delivered in a standard retail packaging, but in a neutral cardboard box. The manufacturer’s own packaging image does, admittedly, show a printed cardboard box with the series name Bangers, the product name, and an illustration, but that image is intended for the store display counter. What actually arrives in the mailbox, according to the two stores, is a discreet cardboard box — which, for a product measuring 37 × 36 centimeters, is relevant information.

Two channels, two bullets, and one control box

The construction is simple and has no electronic parts built into the body. The manufacturer specifies two openings and textured channels, and describes the product as provided with a vibrating bullet insert. The packaging specifies the number as two intense vibrating bullets and shows them as two small eggs connected by a cord to a common control box.

There is a discrepancy in the manufacturer’s own material that is worth noting: the running text on the product page talks about one bullet insert in the singular, while the packaging image on the same page expressly states two. All Swedish stores that describe the number — Blush Me, SexleksakerOutlet, Vuxenkul, Joyland, and Lekosmek — state two. With five stores and the manufacturer’s own packaging on one side and a loosely worded statement in the web text on the other, two is the figure that is supported.

The two textured channels

The product has a vaginal and an anal opening. The manufacturer states that the channels are textured; Joyland describes the surface as ribbed and silky-smooth and the firmness as soft. The manufacturer’s own cross-section image shows two separate channels with different structure — the upper one with a chain of evenly sized balls, the lower one with wider ridges and an irregular profile. So the two channels are not identical, which is the only technical difference between them besides their placement.

What the manufacturer doesn’t publish is just as important: nowhere is the length of the channels, their diameter, or the insertion depth stated in the manufacturer’s materials, and none of the seven stores fills in the gap. The depth is limited purely geometrically by the fact that the product is 13 centimeters deep in its shortest dimension, but which part of that measurement is the channel and which part is solid material is not shown. It’s the single largest gap in the specification, and a reasonable question to ask the store before buying it.

How is the vibration in Big Bubble Butt powered?

With loose batteries, not with a rechargeable battery. The manufacturer states the battery type is AAA and that batteries are not included. Joyland specifies three AAA batteries of type LR3, which means they have to be bought separately, and Taboo specifies the motor type as battery-powered AAA. Blush Me states “laddningstyp AAA” in its specification box, which is the same information worded in a misleading way—there is no charging, only a battery replacement.

Control happens via a control box on the cord. Joyland describes the modes as “multispeed,” meaning stepless or stepped speed control, and Vuxenkul writes that the bullet has several vibration speeds to choose from. Neither the manufacturer nor any of the stores publish how many modes or speeds it involves, and none state operating time per battery set, motor power, or sound level in decibels. Information about an exact decibel value for this product therefore lacks a source from the manufacturer.

The construction has both an advantage and a disadvantage that are worth weighing against each other. The advantage of using loose AAA batteries is that the electronics are completely replaceable: if one bullet breaks, the rest of the product is unchanged, and there’s no built-in lithium-ion battery that degrades over the years and makes the entire product unusable. The disadvantage is that the cords and the box hang loosely during use, that batteries are an ongoing cost, and that the vibration is transferred point-by-point from an egg instead of being distributed through the body. It’s a simple solution, not an advanced one—and the price doesn’t always reflect that.

Hands-free and positions—what the weight buys you

The manufacturer’s packaging states that the product stands firmly on any surface for use without hands. That’s the concrete promise in the design, and it follows from the weight and from the fact that the underside is flat.

What can be established based on the shape is that the product is molded in a single stance—a position that stores call doggystyle—and that alternative positions therefore have to do with turning the product itself rather than changing the angle. Vuxenkul and Lekosmek describe it as placed in that position, and Taboo highlights its stability. For comparison, Pipedream explicitly markets its Fuck Me Silly series as usable in multiple positions, and that series is designed with a larger proportion of body—but also with significantly higher weight.

Cleaning, talc, and storage — what determines its service life

With a product made of porous material, care is not a detail but the factor that determines how long the product can be used. Here, the manufacturer publishes nothing at all: there are no cleaning instructions, no material advice, and no care manual on the product side. Everything that follows is therefore store information, and it is marked as such.

Waterproof without an IP rating — what that means

The manufacturer states its water tolerance with a single word: "Waterproof". No enclosure rating is published according to IEC 60529, neither IPX7 nor any other value. Without a rating, there is no tested definition of what "waterproof" means for this particular product — whether it can be submerged, whether it can handle running water, or only wiping it down.

From a purely construction standpoint, the question is less dramatic than it is for an electronic product, since the body is solidly molded without any built-in electronics. What needs to be kept dry is the bullet and the control box, and they are removable. Vuxenkul’s instruction is the most concrete that has been published: clean after every use with toy cleaner or mild antibacterial soap and water, and store the product in a container protected from dirt and dust. Taboo and Blush Me describe the product as easy to clean without specifying how.

A general piece of advice that applies regardless of the manufacturer: a channel that isn’t dried properly on the inside is the most common cause of a soft-plastic product starting to smell. With a product of this size, it’s not possible to turn the channels inside out, which means the drying time becomes long and the product needs to stand upright and air-dry before it’s put away.

Which lubricant works with TPR?

Water-based. Joyland expressly states "rec. lubricant: water-based" in its specification table, and Vuxenkul writes that the material is compatible with all water-based lubricants in the store’s range. The manufacturer publishes no recommendation.

The reason behind the recommendation is chemical and applies to the entire material family. Silicone-based lubricants attack soft elastomer surfaces and make them sticky and more porous over time; oil-based products like coconut oil penetrate the material and leave behind a film that can’t be washed off. Water-based lubricant is the only one that does not interact with the material, and the downside—that it dries in and needs to be topped up—is a small cost compared with destroying a product worth several thousand SEK.

Why are talc and renewal powder recommended?

Lekosmek is the only one of the seven stores that addresses the issue, and the advice is worth understanding: after cleaning and drying, the surface is powdered with talc or a so-called renewal powder to preserve the softness. The reason is that soft elastomers become sticky over time when the softeners migrate to the surface. A thin layer of powder binds to the surface and makes it regain a dry, skin-like feel instead of feeling tacky.

This is a maintenance step that a silicone product doesn’t have, and it’s reasonable to factor it into the total cost. A product made of porous material requires cleaning after each use, proper drying time, and powdering—and it should still be considered a consumable over the next few years rather than something that lasts decades. The manufacturer publishes no expected lifespan and no information on how the material ages.

Hidden Desire Big Bubble Butt compared with the alternatives

Three comparisons are relevant: versus the manufacturer’s own larger model, versus the best-known competitor in the category, and versus the competitor’s mid-sized variant. All specification details below come from the respective manufacturers’ own product pages, and all prices come from the shops’ product feeds on July 29, 2026.

Versus Hidden Desire Big Ass Milking Bitch 16 kg

Same manufacturer, same series, double the weight. Big Ass Milking Bitch weighs, according to Hidden Desire, 16 kilograms, is cast in the same material—the manufacturer calls it Realistic Love Skin—and has a textured channel. The functional difference is that this model has an active so-called milking function with selectable rhythm instead of loose bullets, meaning built-in mechanics rather than an insert. The price is 3 396 SEK at Joyland versus 1 526 SEK for Big Bubble Butt, i.e. 1 870 SEK more.

It’s worth noting what’s missing from the comparison: the manufacturer publishes no measurements at all for the sixteen-kilo model—neither length, width, nor depth—which makes it impossible to compare the size other than by weight. So the person choosing between the two is choosing between a model with published dimensions and loose bullets, and a model with double the weight, more advanced mechanics, and no published geometry at all. For a product that’s supposed to be kept somewhere in a home, the latter is a real drawback.

Mot Pipedream Fuck Me Silly Bubble Butt — almost double the weight

Pipedream's Fuck Me Silly series is the most established in the category, and Fuck Me Silly Bubble Butt is the direct counterpart to this product. Pipedream states that the model contains over 32 pounds — about 14,5 kilo — of the material Fanta Flesh, and describes it as the brand's largest and heaviest masturbator. Like Hidden Desire's model, it has two openings. Lustly lists it at 3 499 SEK, i.e. 1 973 SEK more than Big Bubble Butt at its cheapest, and the store states the dimensions as 30,5 × 38,1 × 27,8 centimeters.

Differences that actually matter: Pipedream's model weighs almost twice as much and, according to the store listing, is more than twice as deep — 27,8 vs 13 centimeters — which is a completely different matter to store. Hidden Desire's model has vibration included in the price via two bullet points; Fuck Me Silly Bubble Butt doesn't. Neither of the two manufacturers publishes channel length, insertion depth, or material composition beyond a trade name. If you choose based on sheer mass and realism, Pipedream wins. If you choose based on price, ease of handling, and that vibration is included, Hidden Desire wins.

Compared with Pipedream Fuck Me Silly 3 — closer in weight

Fuck Me Silly 3 is the mid-sized model in the same series. Pipedream states over 20 pounds, i.e. about 9 kilo, which is close to Hidden Desire's eight. The difference is that Fuck Me Silly 3 is a more complete lower body with thighs and feet instead of only a backside, which makes it longer but not heavier to a corresponding degree.

The price range makes the comparison especially clear. On Lustly, Fuck Me Silly 2 Mega Masturbator is listed at 2 895 SEK and Fuck Me Silly Mega Masturbator Butt at 5 499 SEK. Hidden Desire Big Bubble Butt costs 1 526 SEK at the lowest, making it by far the cheapest way to get into this product class — but it's also worth saying plainly that none of the manufacturers in the comparison publish what you normally expect from a specification: none states material composition, none states channel dimensions, none states warranty, and none states expected service life. As a whole, the category sits several steps below what, for example, silicone vibrators report.

Price range: 1 526 to 2 998 SEK — and a duplicate listing

Seven Swedish stores sell the item with EAN 8713221820297, and together they provide eight price entries because Sexonic lists the same barcode twice. Cheapest is Joyland at 1 526 SEK, and the most expensive are Lekosmek and Taboo at 2 998 SEK each. That is 1 472 SEK or 96 percent difference for exactly the same item number and the same packaging.

The stock situation is unusually good in this comparison. Five of the seven stores had the product in stock at the price check: Joyland at SEK 1 526, Blush Me and SexleksakerOutlet at SEK 1 795 each, as well as Lekosmek and Taboo at SEK 2 998. Vuxenkul at SEK 2 099 and Sexonics both listings at SEK 2 694,84 were sold out. That means that the difference between the cheapest available and the second-cheapest available is SEK 269, and that the difference between the cheapest and the most expensive store that actually has the item at home is as much as SEK 1 472.

The price spread isn’t due to any store selling a different variant. All of them either list the barcode 8713221820297 or their own item number linked to it, and Taboo additionally prints both the barcode and the manufacturer’s item number 17040 in its specification table. So it comes down to the stores’ own pricing of an item that isn’t being price-pressured—and that’s exactly the kind of situation where a comparison pays off the most. Calculated per kilo of material, the cheapest store is just under 191 SEK per kilo and the most expensive is 375.

Two things to check at checkout. Shipping: several stores state free shipping for this item in their feeds, but a product weighing eight kilos and 37 × 36 centimeters is in a different shipping segment than a regular sex toy, and the shipping cost may be added separately. Batteries: three AAA batteries are not included according to Joyland, so factor in a pack in the total cost if you want to be able to use the vibration right away.

Who is Hidden Desire Big Bubble Butt for—and who isn’t?

It’s for you if you want the physical weight and stability of a torso without paying what Pipedreams equivalents cost, and if you have a storage space where a cardboard box measuring 37 × 36 × 13 centimeters can stand without getting in the way. It’s for you if you want two different channels in the same product, and if you see the value in the vibration being housed in interchangeable bullets with loose batteries instead of in a built-in battery that will one day run out. And it’s for you if you want to get into the category at the lowest possible price: SEK 1 526 is the cheapest price in the entire comparison.

It doesn’t suit you if you have requirements for a material declaration. The manufacturer can’t even keep TPR and TPE separate on its own product page, publishes no phthalate information, and only writes “bodysafe: yes.” It doesn’t suit you if you want a non-porous material that can be properly cleaned—there are no silicone products in this size class at this price, but the difference in hygiene is real. It doesn’t suit you if you lack space: eight kilos that need to be carried to the bathroom after every use and then stored dry and dust-free is a commitment. And it doesn’t suit you if you want to know the insertion depth, channel length, number of vibration modes, or sound level before buying, because none of that is published either by the manufacturer or by any of the seven stores.

One last thing that belongs in the decision. The question of discretion is bigger here than for almost every other product on this site. A vibrator can be put in a drawer. This product can’t be discreetly tucked away in the blink of an eye; it can’t be taken on a trip, and it has to dry completely between uses. Anyone living in cramped quarters or sharing a home should factor that in before the money leaves the account—it’s a practical limitation that no specification mentions.

Warranty, complaints, and the right of withdrawal

Hidden Desire does not publish any manufacturer warranty for this product. Neither the product page nor the manufacturer’s item data states any warranty period, and none of the seven stores lists a warranty that comes from the manufacturer. Lekosmek offers its own two-year product warranty on what it sells, but that’s the store’s commitment and it only applies to purchases made there.

What does always apply, though, is your statutory rights—and they’re stronger than many people think in this category. Under the Consumer Sales Act (konsumentköplagen), you have three years’ right to complain about defects with the item, regardless of whether the manufacturer promises a warranty or does not promise a warranty. An original defect—a crack in the casting, a bullet that never worked, a control unit that’s dead on arrival in the box—is a defect you can complain about with the store. Normal wear and aging of the material is not.

For distance purchases, you also have a right of withdrawal for fourteen days under the Act on Distance Contracts and Contracts Outside Business Premises. Please note that in practice the right of withdrawal is strongly limited for hygiene products that have been removed from a sealed package—for a product like this, that means that in practice you can’t withdraw from the purchase after the packaging has been opened. The right to complain about defects applies, however, always, and it isn’t affected by the seal being broken. If you have questions about what applies in your case, Konsumentverket guides you via Hallå konsument.

A practical tip that follows from all this: save the box until you have tried both channels and the bullet, and check the casting in light before the product is used for the first time. A casting defect is almost always visible right away, and it is considerably easier to file a complaint for an unused product than for a used one—even though the law gives you the right in both cases.
