King Cock Plus Thrusting Cock with Balls: review

King Cock Plus Thrusting Cock with Balls at a glance

King Cock Plus 16.5 cm Thrusting Cock with Balls is Pipedreams’ attempt to build a small sex machine into the base of a realistic dildo. The product has three separate motors: a piston motor that pushes the shaft back and forth, a heating element that raises the material’s temperature, and a vibration motor located at the top of the shaft. The manufacturer markets the combination under the name Triple Threat, and that is the name several shops have adopted.

The specification looks like this according to the manufacturer: total length 27.1 centimeters, of which the dildo itself measures 16.6 centimeters and the insertable part is 14 centimeters. The insertion diameter is 3.6 centimeters. The thrust length is 2.5 centimeters — an inch — and the movement happens entirely inside the product. There are seven thrust functions, seven vibration functions distributed across three speeds and four patterns, and a heating function. The material is listed as TPE and ABS plastic. The battery is lithium-ion type, charged via a magnetic USB cable, and according to the manufacturer 25 minutes of operating time after 2.5 hours of charging. The warranty period is one year. In this market, the item is sold by Sinful and Harmony.

This review is about the variant in light skin tone with EAN 603912765786, the manufacturer’s item number 572821 — in the retailer channel it is most often written as PD5728-21. The number is matched against the gtin field in the page source on the manufacturer’s product page and against the UPC number printed on the first page of the manufacturer’s PDF manual. All six shops list the same EAN, even though they use four different product names.

Three motors, three buttons: what “triple threat” means

What sets this product apart from a regular vibrating dildo is the piston motor. A vibration motor creates motion by spinning an unbalanced weight, which produces shaking but no movement. A piston motor, instead, converts rotation into a straight back-and-forth motion, and that’s what makes the shaft actually move relative to the black motor housing. The manufacturer specifies the thrust length as one inch—2.5 centimeters—and describes the motion as completely internal. So it’s not the entire product that moves; it’s the dildo that slides in and out of the casing.

The heat function is the second motor in order, even though technically it’s a heating element rather than a motor. The manufacturer states that it heats the product’s outer material to body temperature in a few minutes. The third is the vibration motor, which, according to both the manufacturer and the shop’s product data, is located at the top of the shaft rather than in the base. The placement has a practical consequence: the vibration reaches the furthest in instead of being distributed over the entire shaft, which is the opposite of how a typical wand vibrator works.

All three can be run separately or at the same time. What can be established is that the combination options are great on paper: seven thrust modes times seven vibration modes gives 49 combinations, and the heat can be added or not for each one. At the same time, what can be established is that all three parts share the same battery, and that the manufacturer’s runtime of 25 minutes applies to the product as a whole.

Triple Threat, Thrusting Cock with Balls eller 16,5 cm?

Few products in this category have as many names as this one, and it’s worth clearing things up before you start comparing prices. The manufacturer calls it King Cock® Plus 6.5" Thrusting Cock with Balls, where 6.5 inches refers to the dildo’s total length. The packaging also carries the subtitle Triple Threat, which refers to the three functions.

• In this market, it is sold by Sinful and Harmony. Other shops list it as "King Cock Plus Triple Threat".
• In this market, it is sold by Sinful and Harmony. Another shop calls it "King Cock: Thrusting Cock with Balls".
• In this market, it is sold by Sinful and Harmony. Another shop uses the manufacturer’s item number in the name and calls it "King Cock Plus 16.5cm Thrusting Cock with Balls"—where 16.5 centimeters is the metric conversion of 6.5 inches.
• In this market, it is sold by Sinful and Harmony. Another shop adds the skin tone: "King Cock Plus Triple Threat Light Skin Tone".
• In this market, it is sold by Sinful and Harmony. Another shop shortens it to "Thrusting Cock with Balls 6.5".

All five descriptions refer to the same item with EAN 603912765786. The practical advice is simple: compare by EAN, not by name. This specific item also has a sibling that’s easy to confuse it with — the 7.5-inch version in dark skin tone with EAN 603912770537, which is sold under the nearly identical name "King Cock: Thrusting Cock with Balls, mørk". So, the model can be both larger and easy to mix up, which is exactly the kind of confusion that makes people buy the wrong model.

Material: Fanta Flesh, TPE, ABS and metal

The material question is the single most important characteristic of a product that is meant to sit against mucous membranes, because it determines whether the product can be kept clean over time. Here’s the answer, clear but not flattering. The manufacturer’s PDF manual states the material as TPE and ABS plastic. TPE is used in the shaft and the scrotum, ABS in the black motor housing. Pipedream markets its own TPE blend under the name Fanta Flesh, which is a brand and not a material designation.

What TPE means for hygiene

TPE is an abbreviation for thermoplastic elastomer, a material class that behaves like rubber but can be melted and injection-molded like plastic. It’s cheaper than silicone and makes it possible to cast very highly detailed surfaces — which is why the realistic veins and the soft glans in this product can be manufactured in this price range at all.

The price you pay is on the hygiene side. TPE is a softer and more open material than silicone, and it absorbs moisture and lubricants in a way that silicone doesn’t. That’s why the manufacturer recommends an antibacterial toy cleaner rather than soap and water alone, and why a TPE product practically never can become as clean as a silicone product of the same age. Fun Factory, for comparison, describes the materials in its Stronic Petite as body-friendly, pore-free, and hypoallergenic — Pipedream doesn’t use that wording for Fanta Flesh.

The day-to-day consequence is concrete: in practice, this product is a one-person product unless it’s used with a condom, and it has a shorter hygienic service life than a comparable silicone product. The fact that the motor housing is ABS matters less, because that part isn’t intended to be inserted. One retailer also adds metal to its material specification — "ABS-plast, Fanta Flesh, Metall" — which reasonably refers to the piston mechanism and the magnetic charging contact. The manufacturer itself does not list metal in its material list.

Phthalates, REACH, and what the EU declaration actually says

Phthalates are a group of plasticizers that are used to make plastic flexible. The Swedish Chemicals Agency (Kemikalieinspektionen) describes several of them as substances that can affect the endocrine system and reproduction, and the most problematic ones are therefore restricted within the EU. Soft plastic products for use against the skin are the product category where the question is most often raised—and TPE is a soft material.

Two retailers print that the material is "ftalatfri & hudvänlig TPE & ABS-plast". It is a store claim, and the manufacturer’s own product page does not repeat it. However, the claim has support in a document that the retailers do not reference: Pipedream’s EU declaration of conformity for model 572821 declares conformity with the REACH regulation (EC) 1907/2006, expressly with the items 51 and 52 in Annex XVII, which are the phthalate restrictions, and it reports testing according to IEC 62321-8, which is the method for determining phthalates in polymers using gas chromatography–mass spectrometry. The same declaration covers the RoHS directive 2011/65/EU, including the amendment (EU) 2015/863, the WEEE directive, and the EMC directive.

It’s unusual for a brand in this price range to publish its EU declaration openly, and that is a plus for Pipedream. However, it doesn’t change the fundamental issue: phthalate-free status is about which plasticizers are included, not about how porous the surface is. A TPE surface can be completely free of regulated phthalates and still be harder to keep clean than silicone.

Measurements and weight: 27.1 cm total, 14 cm insertable

The manufacturer’s manual provides unusually detailed measurements, broken down into the product’s two parts. The entire product measures 27.1 centimeters. Of that, the black motor housing takes up 10.5 centimeters in length and has a maximum diameter of 5.5 centimeters. The dildo measures 16.6 centimeters in total, of which 14 centimeters is insertable, and the insertable diameter is 3.6 centimeters.

The weight is given as 0.7 lbs, i.e. 11.2 oz—just under 320 grams—for the product, and 0.9 lbs, 14.4 oz, for the entire package. The package measures 12.7 × 33 × 7.6 centimeters, making it a noticeably large cardboard box for a product with a 14-centimeter insertable length. This is explained by the motor housing: nearly 40 percent of the product’s total length is machinery, not dildo.

What can be concluded from those figures is that the product requires a grip and space that a typical dildo does not. The motor housing’s 5.5-centimeter diameter is significantly wider than the dildo’s 3.6, which also sets a physical limit on how deeply the product can be used regardless of what the insertable length says. It’s also not harness-compatible in the way a typical King Cock with a flat base is, because the entire bottom is taken up by the motor and charging contact.

When the manufacturer’s own figures don’t match

Here there is a discrepancy that is worth printing out, because it lies within the manufacturer’s own documentation. The measurement fields on Pipedreams product page state a total height of 26.7 centimeters and a width of 3.8 centimeters, while the manufacturer’s PDF manual states a total length of 27.1 centimeters and the insertion diameter of 3.6 centimeters. The difference is four millimeters in length and two millimeters in width—small numbers, but it’s the same manufacturer that lists both.

The retailers follow the manual rather than the product page. One retailer states exactly 27.1 centimeters and 3.6 centimeters. Others round to 27 centimeters and 3.6 centimeters, and describe 3.6 as a "maximal diameter"—which is wrong according to the manufacturer, because the motor housing measures 5.5 centimeters and therefore is the product’s truly largest diameter. Another retailer states 27 centimeters and 3.5 centimeters, one tenth of a centimeter below all the others. Where two retailers contradict each other, the manufacturer wins, and the most detailed documentation from the manufacturer is the manual: count on 27.1 centimeters total and 3.6 centimeters insertion diameter.

This is how the three functions are controlled

The interface consists of three buttons on the front of the motor housing, and the manufacturer describes them in the same order from top to bottom: thrust, heat, vibration. Another retailer describes the same layout and adds that the three motors are controlled completely separately. The logic is identical for all three buttons, which is a strength in a product with so many functions: hold for three seconds to start or turn off, press briefly to move on.

In practice, that means you can never accidentally turn the product off when you meant to switch to another setting, and you can never accidentally switch setting when you meant to turn it off. It also means that each on and off takes three seconds, which is a long time when something feels wrong. The manufacturer does not publish whether the product remembers the last used setting when it is restarted.

Thrust function: 2.5 centimeters and seven patterns

The thrust length is the product’s defining number, and it is 2.5 centimeters. That is an inch, which is the measurement the manufacturer actually designed it for—the metric figures are conversions. The movement is entirely internal: the shaft slides out of and into the motor housing, while the housing stays still.

Seven thrust functions does not mean seven speeds. The manufacturer writes "7 functions," and other retailers describe them as seven unique thrusting patterns versus seven different "in and out" speeds. Exactly how those seven are divided between pure speeds and rhythmic patterns is not published by the manufacturer, and the two retailers contradict each other on that point. What can be established is that the number is seven and that they are stepped through with short presses of the top button.

Two and a half centimeters is a short stroke length compared with a standalone sex machine, but that’s also the entire point of the design: the movement fits inside the product, so the product can be held steady in the hand or wedged in place and still move. Compare it with a pulsator like the Fun Factory Stronic Petite, which has no visible stroke length at all and instead moves an internal weight back and forth so that the entire product moves. It’s two completely different mechanical solutions for the same idea.

Heat function: what the manufacturer promises—and what it doesn’t promise

Heating is the function that’s marketed the most aggressively and specified the least. The manufacturer writes that the product “heats up quickly to body temperature in a few minutes” and that the function is started by holding down the middle button for three seconds.

What temperature the product actually reaches, how long it takes in minutes, and whether the heat is regulated with a thermostat or simply runs at fixed power—Pipedream does not publish this, neither on the product page nor in the manual. None of the shops lists any value either. The only hard figures in the manufacturer’s materials that relate to temperature are the safety limits: the product should be used within 0–45 °C and must not be exposed to temperatures above 60 °C. That says something about the design’s upper limit, but nothing about how warm the surface becomes during operation.

One more thing belongs here. Heat costs battery power, and the manufacturer’s operating time of 25 minutes is given as a single number without specifying which functions are turned on. If you run all three at the same time, it’s reasonable to expect less than 25 minutes, but the manufacturer publishes no operating time per function, so it isn’t possible to put a number on how much less.

Vibration: three speeds and four patterns

The vibration section is the only one of the three that the manufacturer breaks down in detail. The seven functions consist of three speeds and four patterns—meaning three steps of constant vibration and four rhythmic programs. The motor sits at the top of the shaft, which the manufacturer expressly states is a design intention to provide point stimulation both internally and externally.

Separating speeds from patterns is more useful than it sounds. Three speeds are few—most pure vibrators in the same price range have five to ten—but most people use the four patterns no more than a couple of times. Expect that in practice you’ll end up with one of the three speeds and combine it with one of the seven impact modes.

Pipedream does not publish sound levels in decibels, either for the vibration motor or for the piston mechanism. None of the shops states any measured value either. What can be established purely in principle is that a piston motor with mechanical gearing has more moving parts than a typical vibration motor, and that products in that class generally are heard more than a simple wand vibrator. We are not going to make up any numbers.

Water resistance: IPX4, not "fully waterproof"

This is the point where most of what is written about the product is wrong, and where the manufacturer’s documentation is unequivocal. Pipedream’s EU declaration of conformity for model 572821 states the enclosure class according to IEC 60529 as IPX4. The care instructions on the product page say the same thing in plain language: clean with antibacterial cleaning and warm water, but do not immerse the product in water. The manual repeats it: "Do not immerse the shock part in water."

One shop still lists the attribute "Water-resistant: Yes" on its product page. This is a shop claim that directly contradicts the manufacturer’s own statement, and when a shop and a manufacturer disagree with each other, the manufacturer wins. None of the other listed shops claims that the product is waterproof, but none of them warns against the opposite either. That makes this line one of the most practically important in the entire review: a user who buys based on that shop's information and takes the product into the shower risks damaging it, and water damage is not covered by the warranty.

What the difference between IPX4 and IPX7 means

The IP code comes from the international standard IEC 60529. The second digit describes protection against water. IPX4 means the product has been tested against splashing water from all directions — so it can be splashed on, wiped off with a damp cloth, and briefly rinsed under a weak stream. IPX7 means the product has been tested for immersion to a depth of one meter for 30 minutes.

The difference between the two classes is not gradual; it is categorical. An IPX4 enclosure is not designed to withstand water pressure, and the magnetic charging contact on the bottom of the product is an open contact surface with two exposed poles. Practically speaking, that means: no use in a bathtub, no shower, no rinsing under running water with the motor housing facing upward. The shaft can be wiped off thoroughly; the motor housing should be kept as dry as possible.

It’s also worth noting that the product is a clear candidate for a higher class in terms of construction—there is no battery compartment cover gap, and it charges magnetically, just like products with IPX7. That Pipedream nevertheless only declares IPX4 suggests that the seam between the dildo and the motor housing, where the plunger moves, is not sealed. That’s reasonable: a moving plunger can’t be sealed as easily as a fixed casing.

Cleaning, lubricant, and storage

The manufacturer states antibacterial toy cleaner and warm water, and recommends a water-based lubricant. Another shop repeats the same lubricant recommendation. The advice matters more for a TPE material than for silicone: silicone-based lubricants break down silicone surfaces, but with TPE the problem is rather that the material absorbs it and becomes sticky, and that oil-based products leave a film that can’t be rinsed off.

Here there’s another internal contradiction in the manufacturer’s own document that’s worth knowing about. The manual’s product-specific care instructions say “clean with antibacterial cleaner and warm water.” The general lithium battery section in the same manual instead says: “clean the product with a soft, dry cloth. Do not use water or chemical cleaning agents.” The second wording is clearly standard text for battery-powered products in general; follow the product-specific advice—a cloth that’s been moistened on the shaft, dry on the motor housing and the charging contact.

The manual also provides three storage tips that apply to the battery rather than the material: store it cool and dry away from direct sunlight, charge it to about 50 percent before longer storage, and keep the charging port free of dust. In addition, there’s a tip that applies to all TPE products but that the manufacturer doesn’t print: don’t store it in direct contact with other soft plastic products, because plasticizers can migrate between materials and make both surfaces sticky.

Battery and charging: 25 minutes of operating time

This line in the specification is the product’s biggest weakness, and the manufacturer states it plainly in the manual: "2.5 Hour Charge Time = 25 Minute Run Time". Two and a half hours of charging gives 25 minutes of run time. The ratio is six to one between charging and use.

It’s short even with the product’s functions in mind. Fun Factory states 2–3 hours of run time for its Stronic Petite on 6 hours of charging—meaning between five and seven times as long, at a charging ratio of about two to one. That a plunger motor that moves 2.5 centimeters of material draws more power than a vibration motor is to be expected, and that a heating element draws even more is obvious. But 25 minutes is a figure that has practical consequences: the product has to be charged before each time you use it, not weekly.

How is King Cock Plus Thrusting Cock charged?

With a magnetic USB charging cable that attaches to two contact points at the bottom of the motor housing. The cable is included in the delivery—the manufacturer’s contents list exactly two items: the product and the magnetic charging cable. No storage pouch, no lubricant sample test, no extra cable.

Magnetic charging has the same trade-off here as on all products in the category. The advantage is that no opening in the housing is needed, which is a prerequisite in order to reach IPX4 at all with a product that has a movable plunger. The disadvantage is that the cable is product-specific: if you lose it, no ordinary USB-C cable works as a replacement. Fun Factory also uses magnetic charging on the Stronic Petite, so it’s not unique to Pipedream—but Fun Factory has a standardized charging connector across its entire range, which Pipedream does not publish any information about.

The manufacturer does not state how charging is indicated, whether the product has a charging light, or any warning for low battery. Fun Factory expressly provides a low-battery warning on its corresponding product. It sounds like a detail—until the battery runs out in the middle of a 25-minute-long session.

The capacity that isn’t published

Pipedream does not publish the battery capacity in mAh or its voltage for this model, either on the product page, in the PDF manual, or in the EU declaration. What is stated is that the battery is of the lithium-ion type—the “Li-ion” marking is on the cover page of the manual—and that it is charged via the magnetic USB cable. None of the six stores publishes any capacity value either.

Without the capacity, you can’t convert operating time into power consumption, and you can’t determine whether the 25 minutes are due to a small cell or to three power-hungry motors. What you can, however, establish is that the manual does not mention that the battery would be replaceable, and that it explicitly forbids disassembling the product or the battery. In practice, that means the product’s service life is the battery’s service life. The manual also states the charging limits: do not charge below 0 °C or above 45 °C, and store the battery at roughly half charge during longer periods of non-use.

King Cock Plus Thrusting Cock compared with the alternatives

Three comparisons are relevant: against the larger sibling model in the same series, against the German pulsator that performs the same task in a different way, and against a regular King Cock without a motor. All the information below comes from each respective manufacturer’s own specifications, and all prices come from the stores’ product feeds on July 29, 2026.

Against King Cock Plus 7.5" Thrusting Cock with Balls

Pipedream makes the same product in two sizes. The larger one is called King Cock Plus 7.5" Thrusting Cock with Balls, is sold in a dark skin tone with EAN 603912770537, and according to the manufacturer’s measurement specifications has an insertable length of 16.5 centimeters versus our model’s 14, a total height of 29.7 centimeters versus 26.7, and a width of 5.5 centimeters versus 3.8. The warranty period is the same, 365 days, and the set of functions is identical.

The takeaway is that pricing in this category is driven by stock availability rather than by what the product costs to manufacture.

So the choice between them is not about price, but about dimensions. An extra 2.5 centimeters of insertable length and an extra 1.7 centimeters of width are big differences in this size class, and the smaller model is the one that fits the most people. If you’re unsure, 14 centimeters and a 3.6-centimeter diameter are the more forgiving starting point.

Versus Fun Factory Stronic Petite, the pricing differs.

Fun Factory Stronic Petite solves the same problem — movement without the user doing the work — with a completely different mechanism. Instead of a plunger that pushes out a shaft, Stronic Petite uses an internal weight that’s thrown back and forth, so that the whole product moves. Fun Factory states a length of 17 centimeters, a diameter of 2.5–3.5 centimeters, a weight of 216 grams, five speeds and three patterns, a memory function, and a retraction lock.

The key difference comes down to two areas. The first is the material: Fun Factory describes its materials as body-friendly, pore-free, and hypoallergenic, while Pipedream specifies TPE. The second is the battery: Stronic Petite is rated for 2–3 hours of runtime, King Cock Plus for 25 minutes. Fun Factory also includes a low-battery warning and a retraction lock—two features that Pipedream doesn’t provide any information about.

What King Cock Plus has that Stronic Petite doesn’t: heating, a separate vibration motor placed in the top, a realistic sculpted look with striations and a base, and a real thrusting motion with a stated stroke length of 2.5 centimeters. If you want realism and warmth, there’s no way around TPE and the short runtime. If you want a product that lasts longer and can be cleaned better, then the pulsator is the rational choice.

Versus a regular King Cock without a motor

The third comparison is the closest one, because it’s the same brand and the same material. A standard King Cock in Fanta Flesh has no motor, no charging, no battery, and no IP rating to worry about — it can be washed however you want, basically lasts until the material gives up, has a suction cup, and is compatible with it. It costs a fraction.

What you’re buying when you pay the difference is movement and heat. So the question isn’t whether a Thrusting Cock is better than a regular dildo — it does things that a regular dildo can’t — but whether the 25 minutes per charge, the shorter hygienic service life, and the IPX4 limitation are worth swapping out for a product that works every time without preparation. For some, the answer is clearly yes. For some, the motor is a feature that gets used three times and then never again.

Who is King Cock Plus Thrusting Cock for — and who isn’t?

It’s for you if you specifically want a product that moves under its own power with a realistic shape, and you know you want heat. That combination—thrusting motion, heating, and vibration at the top—presented in a realistic form language with a shaft, is hardly found anywhere else in this price range. It’s for you if you want to be able to run the functions independently of each other, and it’s for you if you prefer a soft, flexible material over the firmer feel of silicone.

It’s not for you if you want a product to rinse off under the tap—IPX4 and the manufacturer’s express prohibition against submersion shut that door. It’s not for you if you prioritize hygiene above everything else, because TPE can’t be kept as clean as silicone over time. It’s not for you if you want to use the product for longer than half an hour without charging. And it’s not for you if you want to share the product with a partner without a condom.

One more thing is part of the decision. The product is 27.1 centimeters long and weighs a little over 300 grams, the motor housing is 5.5 centimeters wide, the charging cable is product-specific, and the warranty period is one year. It’s a product that should stay at home in a drawer with its own cable, not one that comes with you in the travel kit. If you want something to take on a trip, you’ll make a smarter choice by leaving it at home.

Warranty, complaints, and right of withdrawal

Pipedream provides a one-year warranty on rechargeable products, counted from the date of purchase, against mechanical defects and manufacturing defects. The manufacturer’s measurements field states a warranty period of 365 days, and the warranty page confirms the same period for the entire category of rechargeable products. That’s short compared with what several of the competitors in the category offer, and especially short for a product with three motors and a mechanical plunger.

Read the terms before you count on the warranty. Pipedream requires both that the product is registered and that you can show proof of purchase from an authorized Pipedream reseller. The manufacturer does not publish which stores count as authorized, and that’s why it’s not a given that a warranty claim will go through just because you have a receipt. In practice, it’s an argument for following the store’s own terms first and foremost.

What always applies are your statutory rights, and they are stronger than the manufacturer’s warranty. In the EU and EEA, consumers buying online 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. 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 applies specifically to this product: save the receipt and the box. With three motors, a heating element, and a moving piston in the same housing, there are more things that can stop working than in a regular vibrator, and a twelve-month warranty expires quickly.
