Uncover Creations Tentacle Grinder II Review

Are you someone who enjoys grinding up against interesting surfaces? Do you prefer hands-free stimulation – or simply find it a lot more “primal” to use your hips instead of using your hands? If that’s the case, this Uncover Creations Tentacle Grinder II Review is going to be for you.

Instead of holding the Tentacle Grinder II up against yourself, you simply sit on top of its textured surface and then wiggle your hips to experience the stimulation. The protruding, textured tentacle offers an elevated, sensation-filled surface to get your rocks off while simultaneously leaving your hands free.

Handcrafted from body-safe silicone, the Tentacle Grinder II is about 7.5″ long with a width of 5.5″. At the highest point, the protruding point is about 1.77″ tall. It’s also almost exactly a pound in weight, perfect for keeping it in place. I highly recommend pursuing Uncover Creations’ measurements list for the toy as each one is handmade, and the mold may change periodically. I’ve found all of my toy’s measurements to match up with their posted measurement.

Every Uncover Creations Tentacle Grinder 2 includes two black nylon straps (2.5 feet each) with quick-release buckles to easily strap the toy down to something. These straps are removable from the toy itself.

As my own addition to the measurement pool, though, I can add that the base itself (sans tentacle) is a nice, thick slab of silicone at about 1.25mm in thickness. This makes for a sturdy, durable surface for the black nylon straps to run through.

My Uncover Creations Tentacle Grinder II is shown in the UC Trademark color with the Silky Smooth Upgrade and Vibrating Bullet.

How Do You Use It?

If you’ve always used standard vibrators or dildos, the idea of using the Tentacle Grinder II might feel a bit overwhelming at first.

But really, the Tentacle Grinder II is more straightforward than your average sex toy.

Simply lay it down on a surface that allows you to sit on it, and then sit on it. Experiment with moving your weight this way and that way to find positions that feel pleasurable for you.

That’s, honestly, all of it – and what makes grinder sex toys so cool.

It’s all about finding what feels best for you while simultaneously making you an active participant in the entire experience.

That’s probably why I have such amazing orgasms with the Tentacle Grinder II as well. Instead of simply laying back and holding an object on myself, I actively need to move my hips and grind against the surface of the toy. I have to put my body into the experience in a way that makes the resulting orgasm feel so much more primal and powerful.

At the same time, my hands are, technically, entirely open for business. I can (and have!) used my hands to type and browse the internet while pressing up against the Tentacle Grinder II. I don’t usually read erotica (in book format), but you could easily do so while sitting on top of the Tentacle Grinder II.

That being said, using a grinder sex toy like this isn’t as straightforward as a vibrator. You don’t simply lay it on top it with your vulva/penis and wait for it to work its magic. You’ll need to do a bit of exploration to find what spots really are best for you.

That may require:

• Leaning forward
• Leaning to a certain side
• Adding more lube
• Adding less lube
• Grinding on it on a firmer/softer surface for more/less plushness
• Grinding on a different area of the Tentacle Grinder II. (Like towards the tip of the tentacle or towards the center of the tentacle.)
• Add the vibrator to the Tentacle Grinder II.
• Remove the vibrator from the Tentacle Grinder II.
• Adding pillows or a “bolster” underneath the Tentacle Grinder II so that it sits higher up between your legs while riding it. This may especially be the case if, like me, you have thicker thighs or plushier labia.
• Adding pillows/bolsters underneath your knees so that you’re pressing less firmly into the Tentacle Grinder II.

It’s all about personal preference, and to figure that out, you’ll have to experiment a bit to find what feels good. (Sorry. I wish there were easy shortcuts I could give you too!)

How Do I Like It for Clitoral Use?

I’m, honestly, really fond of using the Tentacle Grinder II exactly how it is – no vibrator required. I’m a big fan of pressure, and the ability to slide against the Tentacle Grinder II with my full body weight is all my body really requires for orgasms. I find that the vibrations tend to distract my brain a bit more than is necessary.

I love that the Tentacle Grinder II has a lot more give than other grinder sex toys on the market. It is made of a semi-firm silicone – but without a firm, plastic interior core unlike most vibrating grinding sex toys on the market. This means you avoid the hard plastic sensation which can occasionally feel painful on your pelvic bones.

Instead, you simply get a soft, squishy silicone that you can grind against.

Unlike most of my other sit-on sex toys, though, I have found that I have to use lube with the Tentacle Grinder II. Most of my other options are made from that super-slick silicone covering a layer of plastic. Since this Uncover Creations version is fully handcrafted silicone, it has a bit more drag than other options – and adding lube really helps things glide along in the best of ways.

I’m also really fond of the gigantic “base” underneath the Tentacle Grinder 2. This ends up catching a lot of the aforementioned lube that I’m using, and it makes it easy to tote it all over to the sink for easy clean-up. I also tend to use the Tentacle Grinder II with a sex blanket or towel to capture any overflow, but it’s surprisingly not as messy as you’d assume. This large base really does a good job keeping it all pretty contained.

Uncover Creations Tentacle Grinder II Review: Anal Use

While sit on vibrators like this tend to be most popular for clitoral stimulation, there’s no hard and fast rule that they can’t be used for external anal stimulation.

So that’s exactly what we did.

After sterilizing the toy (because yay! It can be sterilized between uses because of its full silicone design!), we covered the tentacle in lube and let my penis-owning submissive sit on top of it to grind his butt hole against the tentacle’s texture.

We both think a different Uncover Creations tentacle style (more about that below!) would be a better fit for him. With his less plushy butt, he found that resting his entire weight on top of the very-protruding tentacle made it hard for him to get the easy leverage he needed for back and forth movements.

However, unlike me, he really enjoys the vibrations cascading through the toy when he simply sits on top and stays still.

So while I’m a grinder on this one, he really loves sitting still on top of it, finding that the tip of the tentacle makes the perfect protruding point to get vibrations up against the entrance in a way that’s difficult to go without a tall, soft, vibrating object to sit on.

We’ve tried this type of “sit on” idea with wand massagers before, but most vibrating toys have ridges, edges, or control panels that make this impossible. The Tentacle Grinder II makes it all possible with the soft silicone that’s nice to sit on.

Uncover Creations Tentacle Grinder II Review: Vibrations???

Yep!

If you’d like, the crafters at Uncover Creations will add an optional bullet vibrator hole and vibrating bullet to your Tentacle Grinder toy.

The bullet hole is standard bullet hole width, and you can fit any standard width bullet into the hole.

If you choose this option, Uncover Creations includes a generic bullet vibrator with your Tentacle Grinder II along with the built-in bullet vibrator hole underneath the sit on sex toy.

The bullet vibrator really doesn’t have a name or manufacturer that I can tell. It’s rechargeable and remote controlled, and it includes instructions on how to use the toy. It’s a plastic, smooth vibrator without much power, but it still works for vibrations. The remote controlled functionality is relatively hit-or-miss, and I generally give up using the remote and swap to simply reaching under the toy to control the vibrations.

Personally, if you already have a bullet vibrator at home, I’d recommend reaching out to Uncover Creations and seeing if you can get the bullet chamber at a discount if you forego the vibrating bullet addition. The included bullet vibrator will do you if you don’t have a bullet vibe at home, but it isn’t the highest quality (or strongest). It isn’t Uncover Creations’ fault; nice, high-quality bullet vibes can run $50-90 – and I’m guessing that would not be the nice, affordable price point they’re going for.

For me, the We-Vibe Tango X fits like a dream into the Tentacle Grinder II, and that’s my bullet vibrator of choice for this Uncover Creations sex toy. It’s pretty much a match made in heaven with its deep, rumbly vibrations transferring throughout the Grinder’s surface.

We’ve also found that long, slender vibrators can be placed underneath the Tentacle Grinder II against this hole (like the Doc Johnson Velvet). It will not fit into the hole, but this nice bullet “hole” on the underside of the Tentacle Grinder II faces toward one end of the toy. This means that even if the vibrator doesn’t fit inside, as long as the tip can be somewhat “contained” by the bullet hole chasm, it will stay in place when trapped between a flat surface and your weight on top of the Tentacle Grinder II.

It won’t work with wand massagers, but for slender, straight vibrators with tapered tips, it gives you a whole lot more power than a standard bullet vibrator. You just have to tolerate a vibrator sticking out from underneath your Tentacle Grinder II – almost like you’re strangling it to death by queening. (I giggled the first time I thought of that.)

The bullet vibrator chamber runs very deeply underneath the Tentacle Grinder, going from one side (the base of the tentacle) to directly underneath the center “hump” of the texture. If you can get a long enough vibrator (the included vibe can be difficult to snuggle that deep), this places the vibrations directly underneath the center hump where it will diffuse throughout the toy.

Uncover Creations Tentacle Grinder II Review: Keeping It In Place

I love the fact that the Tentacle Grinder II‘s underlying base is made from flat, untextured silicone. It makes it one of the best grinders I’ve ever had at simply staying put. A lot of other grinder toys on the market use a plastic base or slippery-smooth silicone base. Both of these options make their toys slide back and forth a bit more during use.

That isn’t the case with the Uncover Creations Tentacle Grinder II. The smooth, untextured underside of the Grinder II means that it adheres itself like a suction cup to flat surfaces, and it has a grippy, non-slip partnership with textured surfaces (like the seat of my computer desk chair).

It’s ridiculously effective. Partnered with my bodyweight on top of the Tentacle Grinder II, this thing doesn’t move at all – no matter how much pressure and back-and-forth movement I seem to throw at it.

Considering that grinding can feel a bit primal and lead to intense, turned-on hip thrusting movements, this is a really refreshing choice from Uncover Creations. It blows their competitors (which I regularly need to readjust) out of the water.

Honestly (really, honestly!), we’ve only used the black nylon straps for testing for the Uncover Creations Tentacle Grinder II review. The backside grips and stays in place so nicely that we’ve never really found a need to pull them out for regular use. Again, it’s just another testament to the design there.

Let’s talk about those straps though!

This tentacle sit-on sex toy includes two, buckle-connected straps. These two straps disconnect at the buckle in the middle of each strap. The edges of the silicone then can be stretched out to easily tuck these buckles through the holes in the Tentacle Grinder ii. You then can wrap the Tentacle Grinder ii around any circular object to snap it onto its surface; just like a snuggly hug!

Now you simply place the Tentacle Grinder II onto any semi-flat surface, wrap the straps around the underside of the object, and climb on top.

Some of my favorite ideas for using the straps:

• Wrap the straps around a favorite pillow
• Set the Grinder on top of an ottoman and wrap the straps underneath it
• Perch the Tentacle Grinder II on top of the arm of your couch
• Get new use from a dining chair by wrapping the straps underneath it, positioning the Grinder on top

Just make sure whatever object/furniture you choose is strong enough to support your weight and the back-and-forth grinding of your masturbation.

As noted, we really haven’t used the included straps all that often with our tentacle grinding sex toy. Almost every surface we place the tentacle grinder on tends to have enough horizontal space and grippiness to keep the toy from sliding around without even needing the straps.

The straps were the biggest help with soft, plushy, movable surfaces like a pillow. It helped ensure the toy stayed in place when the surface underneath it was prone to moving and squishing.

The straps are also really helpful with any surface that isn’t quite wide enough to support the Tentacle Grinder’s 5.5″ width. For example, if your partner’s thigh is slim enough to have less than 5.5″ in surface width, the straps can help keep the toy nicely “anchored” in place with a bit of tension. This applies to furniture too – like if the arm of your couch happens to be slender in width.

If choosing to use the Uncover Creations Tentacle Grinder II with a pillow, I’d recommend a firmer pillow. Choose a firm pillow or ball/fold up your softer pillows until they’re firmer. This leads to less depression of the Grinder II during use which allows you to better feel the texture against your body.

It’s just as easy to remove these tether straps for easy cleaning of the sex toy too. It also makes for easier storage too.

I love how easy they go on and off. It means I never really have to prep for where/when I want to use the Tentacle Grinder II. I simply decide I want to play with the grinder and pick a spot. I’ll try the Tentacle Grinder II in that spot, and if it needs a bit of extra support to keep it from wiggling around, the straps can be “installed” within 30 seconds.

Can I Put the Tentacle Grinder II on a Partner?

You might be looking for a new way to explore mutual masturbation with a partner. You might simply be hoping to make out with your lover while simultaneously getting off. Whatever the case, you might be popping into this Uncover Creations Tentacle Grinder II review hoping to learn if the toy can be placed on a partner.

The answer is yes!

Some of the other sit-on vibrators on the market (looking at you, Rocks-Off Ruby Glow) offer sturdy, right-angle, plastic edges. These plastic edges really press uncomfortably into your partner’s skin. Add body weight on top of that toy, and your partner taps out in pain long before the “rider” actually gets anywhere.

This Uncover Creations grinder avoids that entirely with the lack of any hard, rigid surfaces.

Instead, all of the edges of this sit on tentaticle vibrator are made from the same super soft silicone as the rest of the toy. They simply compress against your partner’s skin with zero pressure points. My partner says they feel the weight of my body, but even with the toy resting underneath me, it doesn’t feel any different from when I’m simply sitting on him. The supersoft silicone of the Grinder II means that it’s there – but nothing about it is solid/firm/hard enough to become a pressure point when my full body weight is sat on top of it.

We’ve used this a few different ways:

• I sat on his lap, and we’ve made out while it added additional pleasure for me.  
• I’ve laid it on top of his thigh to grind up against it for my own pleasure while giving him a handjob. This works really well for our small penis humiliation kink as I can easily say I’d “rather” play with the toy than him.
• He has laid out on the edge of the bed, and I sat a tiny bench next to the bed. I placed the Uncover Creations toy on top of the little bench, and I could sit and grind against it while giving oral sex.
• He has sat on top of it at his computer desk while masturbating to porn. While it doesn’t insert into any orifice for him, the back-and-forth dragging against the tentacle texture adds really nice external anal sensations.

There are a whole lot of other ways we could use it, but those are the ones we’ve just experimented with so far.

I do recommend experimenting with whether you can use the bullet vibrator inside of the Tentacle Grinder II while using it on top of a partner, though. We find that the included bullet vibrator sticks out a bit, and it will become a hard plastic pressing into a partner’s body. Some of your tinier, skinnier bullet vibrators were less noticeable, but they provided less power as well.

For the most seamless, pain-free partner use, we’ve gone vibrator-free while using the Uncover Creations Tentacle Grinder II.

On the few times where we’ve wanted to try adding vibrations to it, we snake a wand massager between our bodies and press the head of the massager up to any spot on the grinder pad. It provides nice, diffused vibrations that go throughout the entirety of the Grinder.

With a bit of creative use, we’ve found ways to share the wand massager between the two of us, too. So repositioning the Grinder pad to sit near my partner’s genitals allows us both to share the wand massager while I enjoy the additional sensation of grinding on the Tentacle Grinder II. It’s a bit of a win-win!

(Expect your partner to need to shower afterwards! The Tentacle Grinder II stays comfortably in place without any hard pressure points, but the heavy silicone definitely encourages sweating of that spot! Add that to your sexual escapade, and the Grinder just simply gives you another reason to hop into the shower together afterwards!)

Uncover Creations Tentacle Grinder II Review: What Are My Customization Options?

The cool thing about Uncover Creations is that you can customize your cost (and experience!) with their large options list. Like, a lot of options:

• Sex toy color combinations
• Strap color
• A silky smooth finish for your silicone
• Vibrating bullet hole built-in with included bullet vibrator

Unlike many fantasy stores that aren’t taking custom color requests, Uncover Creations still is – and they’ll allow you to choose the colors that your new Tentacle Grinder II will show up with. Do you want a solid color? Marbled colors? Exactly as it’s pictured on the website? All of those are options you can have. They even have Glow in the Dark pigments!

Their website’s Colour Guide is really helpful, and it includes multiple shades of most colors to help you figure out the exact color combination you had in mind. It even includes a picture gallery of various toys they’ve crafted to see the colors in use (though I’d love to see them add which colors, exactly, are pictured with each one of the gallery photos).

The Uncover Creations Tentacle Grinder 2, in UC Trademark color, looks exactly how it was pictured online. It’s impressive.

Once you get past the color, you get to explore the other special features you can choose. 

I’m talking about choosing different strap colors for your included straps. For a small upcharge, you can swap out your straps to a nylon that better matches the custom color combination you chose. Badass.

From there, you can add on a “silky smooth upgrade” if you like. By using an additive derived from Durian tree nuts, Uncover Creations reduces a bit of the natural grippiness of silicone for a smoother, sleeker feel to the silicone. You’ll definitely still want to use lube with it (it doesn’t turn the silicone into plastic!), but it does seem to reduce its propensity for gripping onto dust and hairs.

Finally, you can opt in to vibrations down the line. If you do, Uncover Creations will build a bullet vibrator hole right into the base of the sex toy. They also include a remote controlled, rechargeable bullet vibrator with your Tentacle Grinder II, so you can get started using those vibrations as soon as you receive the toy.

Are There Other Tentacles?

Yep! Uncover Creations appears to have cornered the market on this whole “ride a tentacle” thing, and I love them for it.

So if the single tentacle vibe of the Tentacle Grinder II isn’t doing it for you, you also have the:

Tentacle Grinder 1 (shown above). And the Tentacle Grinder 3 (shown below).

I, personally, know that the Tentacle Grinder II is the best fit for my body (I really like one firm stimulation point to grind against, and with thicker vulva, I need something with a deep protrusion to get it into the right place), so keep your body’s preferences in mind while choosing the tentacle that’s best for you. Sometimes your eyeballs don’t know what’s best for your genitals (ain’t that the truth?).

They even have a cock ring with attached tentacle grinder if that sounds more up your alley.
