After buying a sex machine, the most fun you can have is selecting the attachments to see which you like best. A good sex machine has enough options to keep you interested for the long haul, but all those choices can be perplexing.
The ultimate sex machine I’ve ever tried is the Motorbunny Buck, for the speed, power, versatility, and you guessed it: the multitude of tech-forward attachments. I’ve put more Motorbunny attachments through the wringer than I can count, and below are the ones that captured my heart and gave me the best time. They motored on my bunny until I felt an attachment.
I’ve started with the best, and my hands-down favorite is the Mt. Gushmore Flat Attachment. Nothing compares to its ease of use, value at that price point, and crowd-pleasing power. But keep reading, as budget options, penetrative powerhouses, wallet-friendly, and gamer-friendly picks loom ahead and may be a better fit for your lifestyle.
Note: Keep in mind that certain sex machines come with attachments, so only buy the extras that didn’t arrive with your sex machine. And one more note: the power doesn’t have as much to do with the attachments as it does with the motor inside the sex machine, so I’ll focus on the design and results rather than the horsepower, or in this case, bunny power.
1. Mt. Gushmore Flat Attachment: Overall Test Winner
Why I love the Mt. Gushmore Flat Attachment:
The first reason I love the Mt. Gushmore Flat Attachment is because of its name. Mt. Gushmore? I’m proud of you, Motorbunny marketing team. It’s a toy that mounts to your machine, and it may just make you gush more. It certainly did the trick for me. And another reason why I love it the most is because I think it is a game-changer for people with vulvas who are leery of the intensity of a sex machine.
Here’s why it stands out on a more serious level. The Mt. Gushmore Flat Attachment is the gateway drug to sex machine use for many clit-havers. When sex machines were new to me, I was far more comfortable trying clitoral vibrations powerful enough to blow my hair back rather than fast, deep, adrenaline-pumping penetration. It’s comfortable, easy to use, and low-risk for pain, making it perfect for people who haven’t gotten into sex machines before.
This Motorbunny attachment is also surprisingly affordable, costing around $40. It works perfectly with the Motorbunny Buck but won’t work with the Original machine. The design is more intuitive than the Low TPE option below because it requires no bending, leaning, or angling. Instead, the tall ridge reaches my clit, and I can sit comfortably for as long as I like, edging or having multiple orgasms.
Lastly, the Motorbunny Buck Mt. Gushmore Flat Attachment is just so versatile. Since the sex machine is compatible with an app (and games, if you have the Playmate Plug-in), customization is endless. But even better, the vibes are so powerful that you could use it at an orgy or girls’ night without worrying too much about hygiene. You can all take turns sitting with your pants on, and the height and power are enough for just about anyone to have an orgasm. It’s the perfect plus-one to a sex party of any kind.
Minor issues I found during testing:
If your clit is too sensitive for powerful vibrations, you won’t get much use out of this, and it won’t work with the original Motorbunny.
Features:
- Material: Non-porous silicone
- Dimensions: 2.8” at highest point
Pros:
- Comfortable to sit on
- Perfect for grinding
- Affordable
- Beginner-friendly
- Textured for extra stimulation
- Excellent value
Cons:
- Only works on the Buck
2. Bunny Slope: Most Beginner-Friendly
Why I love the Bunny Slope:
Next is another sex machine attachment with a killer name. It’s the Bunny Slope because it’s made for your first time! The name rings true, and I think it is the most beginner-friendly in the universe of attachments I’ve tested. The Slope is a gently inclined, non-penetrative model for clitoral vibrations. Whether you have the original machine or the Buck, you can pair it with a Slope—just remember to double-check that you buy the right one. It’s comfortable to straddle, easy to use, and the orgasms are inescapable.
This was the perfect attachment for me during my first ride. Penetration can feel intimidating coming from a machine, and the dimensions of this are perfect for getting used to straddling a one until climax. It also works well for me as a warm-up before penetration or other partner play.
The Bunny Slope costs $100, which is on the steep side. But the body-safe, durable silicone should last for years. I’m several years into my ownership of a Motorbunny sex machine, and the Slope looks like it did on day one. It’s easy to clean, and you don’t necessarily need to use lube or take off your clothes to climax. It’s the best introduction to the extreme sensations for people who are leery of doing too much too quickly.
Minor issues I found during testing:
$100 is a high price tag for an attachment made for beginners.
Features
- Material: Silicone
- Dimensions: 12.1” long, 3.7” high
Pros:
- Comfortable
- Accessible
- Easy to clean
- Durable
Cons:
- Somewhat pricey
3. Mt. Gushmore + Vac-U-Lock: Best Dual Stimulation
Why I love the Mt. Gushmore + Vac-U-Lock:
Mt. Gushmore + Vac-U-Lock attachment was made for those who love rabbit vibrators but want the wildest sensations available, and some of the time, that’s me. This product offers the best of both worlds: a Vac-U-Lock dildo adapter for G-spot targeting, and the Mt. Gushmore slope for vibrations that reach your clit. All this for only $60 is a steal in my book.
Further, the dual stimulation is perfect for learning to have a blended orgasm. My first blended orgasm wasn’t on a sex machine, but I’ve had several on them since then. The benefit of learning on a sex machine is that you won’t fail because of a lack of power. If your body is ready, this will make it happen. This is a time-honored go-to when I want to squirt. Plus, it is hands-free, so I could play a video game while I have a blended orgasm, which is the kind of multi-tasking I live for.
I can’t really grind against it since the dildo keeps me in place, but the sensations are everywhere. Even on the lowest settings, the experience feels otherworldly and overwhelming in the best possible way. The adaptor lets you control the dimensions so you can start slowly and work up to larger sensations as you get comfortable.
Minor issues I found during testing:
The Mt. Gushmore + Vac-U-Lock doesn’t work with the original sex machines. Finding a comfortable position can take a few attempts.
Features
- Material: Platinum-cured silicone
- Dimensions: 2.8” slope
Pros:
- Dual stimulation
- Could help you learn to have a blended orgasm or squirt
- Affordable
- Hands-free stimulation
Cons:
- Can’t use stimulations separately
- Doesn’t work with the original sex machine
4. Fluffer Playmate Haptic Plug-in: Best for Gamers
Why I love the Fluffer Playmate Haptic Plug-in:
Though this is loosely a Motorbunny attachment, I’m so fond of it that I need to include it on my list of faves. The Fluffer Playmate Haptic Plug-in doesn’t attach directly to the Buck sex machine, but it pairs with it. It works in tandem with it, giving you sex-machine power that connects directly to in-game experiences. It’s one of the most unique, interesting things I own, and it’s the cornerstone of every date night in my household.
While other sex toys often have apps with in-app gaming that mimics popular games, the Fluffer Playmate Haptic Plug-in works with the games I already enjoy, like Mario Kart and Donkey Kong. It is compatible with any USB-C-ready controller, and it responds to more than just my hands shaking or tilting. It translates in-game experiences into stimulations, so I can climax while I beat my partner at Mario Kart. There is no better feeling; I can promise you that. You can use the Fluffer Playmate Haptic Plug-in with PlayStation, XBOX, and Switch, and it’s compatible with nearly all the Motorbunny toys, including the Original and Buck sex machines. I haven’t gotten tired of it yet, and I have so many more games I want to try.
Lastly, I love the aesthetic. It looks like a Toys “R” Us product from the 90s, and it comes with a protective storage case. Yes, it costs $170 at full retail, but it’s basically like having a Dave & Buster’s that helps me climax in my living room. It’s so worth the expense, especially for people who enjoy gaming.
Minor issues I found during testing:
Some games provide more feedback than others, so how much you enjoy this might depend on your taste in video games. It also requires an additional purchase; you must have this plus a Motorbunny sex machine or sex toy. Lastly, pairing can take a couple of tries.
Features
- Material: ABS plastic
- Dimensions: 1.2 x 1.8”
Pros:
- Compatible with XBOX, PlayStation, and Switch
- Perfect for game nights
- Translates in-game experiences into sensation instantly
- One-of-a-kind orgasm
Cons:
- Occasionally finicky to pair
- Must buy or own an additional compatible product
5. Doc Johnson Vac-U-Lock Adapter: Most Versatile
Why I love the Doc Johnson Vac-U-Lock Adapter:
The Doc Johnson Vac-U-Lock Adapter is clutch for anyone who owns a Motorbunny Buck. It’s only $60, but it provides access to a vast range of dildos for those who crave the intensity that only a sex machine can provide. It’s not a dildo itself, but it securely fastens hundreds of dildos, ensuring I never get bored with the selection.
With this adapter, I have access to two types of sensations: thrust and G-thrust. One motion goes straight up and down, and the other angles for better G-spot targeting. Plus, with the number of colors, sizes, textures, and styles of dildos I can use, I will be exploring different sensations for the rest of my life. It adds never-ending customization for dildo collectors and anyone who enjoys penetration. This adaptor allows me to try so many kinds of dildos and learn about myself in the process. What exactly did I learn? I learned that I will never get tired of trying new dildos.
Though this attachment isn’t a dildo, it keeps the dildos right where I need them, which is of the utmost importance to me when I’m riding a machine with speeds that never fail to shock me. Sturdiness is everything. Without this attachment, I would be limited to dildos that came with the machine, which aren’t lifelike. When I crave a real-life fantasy with a veiny, humongous dildo, the only thing that can fill that void is the Doc Johnson Vac-U-Lock Adapter.
Minor issues I found during testing:
The Doc Johnson Vac-U-Lock Adapter is only compatible with the Motorbunny Buck, not the original sex machine.
Features
- Material: Platinum-cured silicone
- Dimensions: Works with dildos of any size, but is roughly 4” high
Pros:
- Adds versatility to the sex machine
- Compatible with any Vac-U-Lock dildo
- Makes fantasies more immersive when paired with a realistic dildo
- Can attach your favorite dildos
- Value is well worth the price
Cons:
- Doesn’t work with the Motorbunny Original
6. Doc Johnson Vac-U-Lock 7.5″ Dong: Best for Penetration
Why I love the Doc Johnson Vac-U-Lock 7.5″ Dong:
The Doc Johnson Vac-U-Lock 7.5” Dong is the obvious choice for anyone who wants realistic penetration paired with the very unrealistic speed, force, and stamina of a sex machine. In short, this was made for dreamers, like me. The Doc Johnson Vac-U-Lock 7.5” Dong comes in colors like caramel or vanilla, but I do wish it came in more skin tones. It’s veiny, girthy, and perfect for fantasy scenarios.
Though you need the Vac-U-Lock Adapter to pair it with the Motorbunny Sex Machine, this dildo is worth every penny thanks to its versatility. This dildo is realistic enough that it would work for cammers, but I love it because it’s big without being painful. At slower speeds, it works well for edging. It’s not overly textured or so huge that I need to reapply lube often within one session, and it is perfect for everyday use. The size is manageable yet inimitable.
Lastly, it costs $35, which is a steal for something this realistic. I’ve tested dildos at twice the price that don’t use materials this silky and skin-like. You can use this dong without a sex machine, too, if you have stronger arms than I do. Since it’s somewhat heavy, I prefer the mechanical thrusts. If I’m feeling extra frisky, it’s always there for use with my partner to simulate a fantasy threesome.
Minor issues I found during testing:
This realistic dildo is made from TPE, which can eventually harbor bacteria, especially if you don’t clean it promptly and consistently. You also must have the adaptor to connect it to a Motorbunny sex machine. Finally, I’d love to see more flesh tones.
Features
- Material: TPE
- Dimensions: 7.5” insertable length, 5.5” circumference
Pros:
- Realistic
- Girthy and heavy for intense G-spot targeting
- Easy to connect
Cons:
- Must buy an adapter in addition
- Made from TPE, won’t last forever and will require more careful cleaning
- Doesn’t have darker complexion options
7. Low TPE Attachment: Our Budget Pick
Why I love the Low TPE Attachment:
What the Low TPE Attachment lacks in a flashy name, it makes up for with comfortable, unique, and affordable stimulation. Motorbunny offers many TPE options, but this one holds a special place in my heart and my wallet because it’s so effective and affordable. This model is for clitoral stimulation, and it’s shaped much like the Mt. Gushmore Flat Attachment, with less height and half the price. It’s often on sale for $20.
The Low TPE Attachment is perfect for sitting on or being bent over while using the Motorbunny. Vibrations travel through the textured TPE, and I can’t get enough of it. If I want to be bent over, you better believe this is my choice. The sensations are so intense that I am often able to sit upright and still have an orgasm. Straddling it clothed or naked is always a good time, though I more often use it clothed, since TPE can become porous and harbor bacteria. Or you can be bent over and receive penetration from behind, making it as much fun to use alone as it is with a partner.
Low TPE Attachment’s design hits the perfect blend of comfortable and intense. The texture is great for anyone who wants extra sensation, but I much prefer to sit on it in my underwear and enjoy over-the-clothes sensations. The cherry on top is how easy it is to use and clean. It is foolproof to set up, which isn’t always the case with sex machine attachments. Between the low price and effortless orgasms, this is what I’d spend my own money on time and time again.
Minor issues I found during testing:
The Low TPE Attachment works with Motorbunny Original but not Buck. TPE materials will not stay body-safe forever, so watch out for wear and tear.
Features
- Material: TPE
- Dimensions: 1.5” high on nub
Pros:
- Easy to use
- Affordable
- Textured for extra sensation
Cons:
- Might need to lean forward to get full experience
- Won’t be body-safe forever and will need to be replaced at some point
