Uncover Creations Tentacle Grinder II Cock Ring Review

Turn your cock ring into a magical grinder sex toy, perfect for clitoral stimulation. Yes, that’s possible! Today, we’re going to jump into an Uncover Creations Tentacle Grinder II Cock Ring review, so you can meet this innovative invention!

A miniature size of Uncover Creations’ best-selling grinder, the Tentacle Grinder II Cock Ring attaches a mini grinder to a circular ring that wraps around a penis. It’s made entirely from stretchy, plushy silicone from tip to tip, with a cock ring loop that can be stretched enough for me to wear it as a bracelet without too much hassle.

The Tentacle Grinder II Cock Ring is 6″ in total length while the protruding tentacle itself is about 3″ in length. The thick base of the ring is almost exactly 0.5″ in thickness, and the bottom of the base to the highest tentacle peak is slightly over 1″ in height.

At rest, the cock ring has a diameter of 1.18″, but it stretches out to 3.14″ in diameter for anyone that wants to use it alongside their huge dildos in a strap-on harness. ;) (Uncover Creations makes quite a few of those too. ;) )

Uncover Creations Tentacle Grinder II Cock Ring Review: How Does It Work?

It’s wild that Uncover Creations is one of the first places I’ve ever seen this design. It seems like such a clear “winner” that it’s absolutely wild that I haven’t seen this before. It’s about how I feel about the OhNuts; this seems like such a “duh” that I’m equally astounded I’d never considered it missing from the market before.

The Tentacle Grinder II Cock Ring works really simply: it’s a cock ring that anchors a protruding grinder for a clitoris-owner to grind on.

The cock ring slides onto a penis (or strap-on dildo) just like a traditional cock ring. Instead of a basic cock ring or a vibrator anchored onto the ring, however, the Tentacle Grinder II ring has a 4.25″ mini grinder that lays flat on the skin while the cock ring is worn.

Once a clitoris-owning partner slides on top of the penis that’s wearing this ring, it allows the clitoris-owning partner to grind forwards and backwards on top of aforementioned penis while grinding up onto the grinder at the same time.

To help anchor the Tentacle Grinder II cock ring in place, the end opposite the cock ring features two slots. These two slots can use an (optional) waist strap, strapping the grinder into place. I did not receive a waist strap for my Tentacle Grinder II Cock Ring review, but it’s an option if you tend to enjoy rough sex.

As you can guess by this description, it means that you’ll likely want to opt for grinding, forward-and-backwards motions while using the Tentacle Grinder II cock ring. You certainly can still enjoy the in-and-out of usual thrusting (the grinder cock ring does not negatively impact that), but the clitoris-owner will get minimal stimulation from the grinder if they’re constantly pulling away from it.

Uncover Creations Tentacle Grinder II Cock Ring Review: As a Grinder

Once it’s on the penis, how well does it work for the clitoris-owner who gets to grind on it?

It’s interesting – in a good way! When we use vibrating cock rings, I’m used to continuing the in-and-out thrusting of “the usual” sex. This means that I get occasional bursts of pleasure from the vibration before the sensations are taken away from my body again.

That doesn’t necessarily work with a grinder cock ring. If I simply touch my clit to the grinder, it doesn’t really provide vibration or any automated stimulation.

Instead, it means that intercourse has to change from an up-and-down, in-and-out motion to a back-and-forth movement. To get the clitoral pleasure from that grinding toy, I have to treat it like a grinding toy with slip-and-slide, back-and-forth movements. It’s very different than the “usual” motions we use during intercourse – but in a good way!

We’ve found that the back-and-forth movements don’t tend to get him as close to orgasm as quickly as the in-and-out motions do AND those back-and-forth movements against the grinder actually get me much closer to orgasm than the in-and-out motions. It’s kinda like the best of both worlds if you’re hoping to make sex last.

I would love to see more height from the Tentacle Grinder II Cock Ring, but that’s personal preference. With squishier thighs and labia, the literal height that the cock ring protrudes away from my partner’s abdomen doesn’t feel like enough height to nestle it comfortably between my labia.

We’ve honestly “solved” that by folding up a washcloth and fitting it underneath the cock ring. It pushes the grinder portion upwards towards where I need it without impacting where he can wear the cock ring half. I don’t think that solution would work as well if we were utilizing the waist strap to fasten the Tentacle Grinder II ring down onto the body, but without the strap, it “solves” the problem pretty well.

The only real downside we’ve found to the Uncover Creations Tentacle Grinder II Cock Ring may be entirely due to our discordant weights. My partner is super slender, and I am most-definitely plus-sized.

When we have this cock ring grinder on his stomach, like in Cowgirl, I need to lean forward, transferring some of my weight forwards, in order to grind up against the Tentacle of this toy. That Tentacle happens to be resting near his stomach, though, and I end up grinding and putting a lot of weight onto the soft tissue of his tummy. It can be a lot of pressure on him, and it can feel relatively uncomfortable for him.

One time I pulled out the Uncover Creations Tentacle Grinder II Cock Ring to play with when we were feeling a bit amorous after lunch. After grinding against the Tentacle a few times, though, we had to call it when it started making him feel nauseous. It has been put on the “do not use” list if he’s recently eaten.

We love our other Uncover Creations Grinders (the Coral Keeper and the Tentacle Grinder II) for placing on his thigh for me to grind against while we make-out. He says that’s probably his preferred way for us to use a grinder – though he doesn’t complain when I pull this cock ring out if intercourse is on the menu. If he had his way, though, with the discomfort we occasionally run into with this, he’d probably rather stick with the full-sized grinders that are comfortable AF for him to keep on his thigh.

So keep that in mind if you’re a couple of differing weights – or you simply have a slender penetrating partner whose body is sensitive to pressure.

Uncover Creations Tentacle Grinder II Cock Ring Review: As a Cock Ring

This unique cock ring has two different “sides” to it. It happens to be a grinder, but it’s also a grinder attached to a cock ring. So how well does that cock ring hold up?

I’m happy to report that it does exactly what it needs to do! We weren’t, necessarily, looking for a ton of restriction from the Tentacle Grinder II Cock Ring. Instead, we wanted a ring that would anchor the grinder half in place and keep it there so I could really enjoy myself. That’s exactly what it delivers.

That’s to say: it isn’t a tight fit on an average penis. The cock ring can even stretch out far enough to fit some of our wider dildos (shown in the feature photos on the Maverick which has a 2″ diameter). The wearer can feel it there, and it has a slight snugness to it, but it doesn’t grip and squeeze nearly as much as some of our cock rings designed for restriction.

This is great for us. It means the cock ring stays in place – but he also isn’t tapping out early because things are starting to throb in an uncomfortable manner. It’s there for marathon sessions as a little bit of support without adding too much squeeze.

Essentially, at least for an average penis diameter, the Uncover Creations Tentacle Grinder II Cock Ring is a comfortable fit that allows for longer sessions. Considering it may take a clitoris-owner a bit to orgasm from grinding against something, this is exactly the snugness that I’d want a cock ring attached to a grinder to have.

If that isn’t the vision you have, a second cock ring could easily be worn on top of the Tentacle Grinder II. Slip the Tentacle Grinder II on, and then add your erection-squeezing cock ring on top of it. (I’d place the Tentacle Grinder II on first, or else you’ll risk giving the Tentacle Grinder II an uneven platform.)

It is worth noting that this cock ring is (literally) 0.5″ in thickness. It will take up 0.5″ of the length real estate on your shaft. Depending on how deep you like your penetration, this is something to take into account before sliding this ring on.

On the other hand, I’d really really love to praise the super-stretchy silicone that Uncover Creations crafted this cock ring grinder from. It stretches out to over a 3″ diameter. While this is unnecessary for human penis use, it’s actually a perfect fit if you want to strap-on a fantasy dildo. ;) This is one of the few cock rings that feels like it was specifically designed to be used with thick fantasy dildos. For example, your partner can strap-on a Tentacle Ovipositor for sliding eggs inside while simultaneously allowing you to grind against another tentacle protruding from the base. It can make for some serious fantasy fulfillment!

Uncover Creations Tentacle Grinder II Cock Ring Review: People with Tummies, Beware

My partner is particularly slim. If you look at most of my feature photos, you can see that he’s like, almost literally half my size. He doesn’t have a tummy to him, and when we place this tentacle cock ring on him, it basically lays horizontally with all of the space in the world around it.

For this Uncover Creations Tentacle Grinder II Cock Ring review, though, I wanted to cover the bases. The biggest base? I was a bit worried about how it would fit a body type that doesn’t have a flat surface for the grinder to lay on.

We piled a couple of pillows on top of his midsection to try to replicate how that might look with a squishier, thicker tummy in the way.

It does, honestly, make the Tentacle Grinder II cock ring harder for the grinding partner to grind against. I think this is compounded if you, the grinder, have a tummy yourself. Pushing forward into the cock ring meant shoving my own stomach pretty firmly into those pillows. The pillows (like flesh) will compress and move around my own flesh, but it made me a little more self-conscious and aware of my stomach in a way that I don’t usually think about while having sex.

I’m happy to report that it didn’t necessarily affect the feel of the grinding, though. As long as I could still make clitoral contact with the grinder, even if the Tentacle Grinder II was on an upward, slanted surface because of “adipose” (pillow) tissue underneath it, it didn’t seem to change the physical sensations themselves.

For the cock ring wearer who was now covered in pillows, he actually enjoyed the Tentacle Grinder II experience more. Those pillows cushioned some of my weight from him, and he says it didn’t feel like I was pressing as firmly into his stomach as I did when we were using the grinder cock ring without the pillows.

So the grinder cock ring’s location made me a bit more aware of my own thicker stomach pressing into “his”, but the cushioning of pillows actually helped reduce how much downwards pressing I was pushing into him stomach while riding the ring.

Let’s Talk Sex Positions

Once you start to sit down and think about it, you’ll realize that any cock ring grinder will limit your potential sex positions.

Any sex position you pick needs to have the cock ring grinder available for, y’know, actual grinding.

If it’s flopping in the wind (if you don’t use the waist strap) or out of reach for the clitoral-owner to actually grind against, you’re not getting the benefits of using this sex toy in the first place.

This definitely has limited our sex positions. We’ve tried some unlikely candidates for this Uncover Creations Tentacle Grinder II Cock Ring review (like Missionary), but they haven’t really panned out, pleasure-wise.

Our gold-star sex position winner tends to be Cowgirl. It gives me the freedom to grind at the pace I need with the space I need for full grinding strokes. It keeps the grinder cock ring laying flat on his body, and it pretty much stays in place with my weight on top of it. Plus, I would assume the view is great from his end. ;)

Any Cowgirl variations have also worked well. Reverse Cowgirl, facing his feet, has been workable if we put his thighs together and stuff a washcloth between them to help make a flat surface.

Angled sex positions where I’m astride at an odd angle also work – though they can be a little uncomfortable for him on the cock ring side of things when it pulls the cock ring up at an odd angle. If you want minimum discomfort for the cock ring wearer, try to select sex positions where the grinder can lay flat. Anything more than a light angled surface can tug on the penis in a relatively uncomfortable manner.

If you want the easiest way to use this grinder cock ring, it’s definitely in Cowgirl. Most of our experimentations have led us right back to Cowgirl to get the most from this sex toy.

(Though it was kinda cool during Doggy. Instead of me grinding against it, it hung downwards, off his penis, and I pulled it up between my legs, palming it up against the vulva. It didn’t quite reach where I needed it to for a strong clitoral orgasm, but it was really neat sensations and almost like a little cock leash for my pet. ;) )

What If I Want the Grinder Bigger?

If you love the look of the Uncover Creations Tentacle Grinder II Cock Ring but wish it was available in a larger size, you’re in luck!
