Be careful when you wish for something

You may get more than you anticipated. I recently added a MB Buck vac-u-lock with a Fun Guy attachment to the toy chest. Oh my!
Combining a Venus with the Buck has elevated my conception of what is possible. I’m 60 and am learning I’ve still got room to experience much stronger Os than I’d ever imagined. Mind blowing, knee buckling, spine quivering, and still building stronger each time.
This machine is way way more than you’ve imagined. MB might be required to integrate a safe word recognition element to the controller. I got my ass pounded for an extra 15 min this morning because I couldn’t operate the controls while experiencing the most intense orgasm of my life. Last control adjustment was to twist Venus to max rpm & air out and then twist both buzz & buck to 11. Closed my eyes and it was euphoric prostate & penis bliss. Thank the makers I was on the easy rider and the handle bars are made well. Venus was milking out its third prize when I hit its off switch. Next breath and I managed to turn off buzz. It was then I got to appreciate what a machine can deliver that a human can’t… thrusting even 2” at 160rpm is incredible. I slowed it down to 2 and just gathered my faculties for another 5-10min.
I’m hoping to recover in 24 hours and take this up a notch. I was way to quick to give in this far.
Be careful what you wish for! MB Buck will deliver more than you have known thus far.

MB Buck

Female here writing a review for the MB Buck. I was really excited to hop on and ride the machine when it arrived.

Upon opening the box I was disappointed to find that the Vacu-lock powder thar was included was a small sample packet, not a bottle like is pictured on the box and the website which right off the bat felt misleading.

The machine was easy to assemble which was nice. My machine must have been defective because I experienced a lag from when the controller was turned on/off and when the machine actually turned on/off. There were a couple of times that the machine wouldnt turn off even when I had turned the controller knobs to the off position. I had to physically unplug it from the wall to get it to stop.

Though the vibrations felt good, it just wasn't for me and did not get me there. My skin reacted poorly to the strong vibrations and I was left feeling like I got a minor rug burn on my thighs (where they were resting on the machine).

At one point the attachment nozzel came loose while I was using it which caused it to start jabbing me really hard. Due to my faulty controller I was not able to stop the machine and it gave me a decent sized purple bruise.

I contacted customer service (which was an overall pleasant and helpful experience) and ultimately ended up returning the item.

I think its a fun idea but I have my doubts on how well its built and how safe it really is. Seems to me for the price I should not experience any issues.

My main complaint is the return policy. There is a $200 restocking fee, and s/h is NOT you will end up shelling out roughly $300 to ship it back. I was tracking the return and saw it had been received by Motor bunny on 11/21. It is now 11/28 and I still have not received a single confirmation email/text saying they reveived the item and I would be getting a refund. Im not sure if it's due to the holidays, but the fact that I haven't received a confirmation that my return has been recieved makes me incredibly nervous about the company and about getting refunded for a defective (and cheaply made) item.

This is just my experience and Im sure that many others have a great experience with the MB buck. It just isn't for me. I give it and my overall experience with Motor Bunny 2/5 stars.


My wife originally thought the Buck was too weird. That lasted right up until we used it. I travel a lot and it has opened up some wonderful long distance “date nights”. She loves it, and really enjoys the dates we have while I’m out of town. It’s expensive but We have no regrets!!!

She must like it

Gave it to her and she's been so nice.

Investing in the MB Buck

In the spirit of Valentine's Day, I have ordered the MB Buck. I have had my eye-on-it since it has been available. I purchased the original MB in 2016 before the MB Link was introduced. I sent it in for repair in 2019 and not only was it repaired, it was upgraded with the MB Link controller free of charge. The MB Link app offers additional options that you can customize. I highly recommend the storage case. I ordered one for my MB Buck. :) The MB Buck does not include the MB Rest, however, I like the introduction of the "Right Angle Wedge". Customer Service is exceptional. I will provide updates on my experience with the MB Buck.

Everyone’s body is different, so the ingenious, patented design of Motorbunny BUCK allows two different styles of attachments and thrust motions. The Thrust Motion Toggles determine the thrust motion. “Thrust” moves straight up and down. “G-Thrust” moves up and forward. The “Thumper” attachment is straight and slightly ridged, and the “Sweet Spot” attachment is angled forward and smooth. Whichever motion and attachment you choose, you’re in for the ride of a lifetime!

What Is a Thrusting Sex Machine?

What Is a Thrusting Sex Machine?

When sex becomes a chore, we may try spicing things up by trying new positions, locations, or maybe even a new partner. What if other possibilities areleft to explore to get you out of your rut? A thrusting sex machine is an exciting option that can enhance your lovemaking or masturbation. Thrusters are motorized, powered sex toys that can fulfill your needs for deep penetration.

If you are in the mood for consistent, rhythmic thrusting, itis time to add a thrusting sex machine to your collection. Thrusting fuck machines have attachments that simulate a penis, vagina, or finger. Thrusters twirl, vibrate, rotate, move up and down, and thrust.

Common Thrusting Machine Features

Before investing in a thrusting automatic sex machine, you should familiarize yourself with a few key details. First, think about how fast you would like the new dildo to thrust. Will its thrust satisfy you and your partner? If your new thrusting machine is not powerful enough, there is a chance it may stall as your muscles contract around the dildo. Carefully selecting a fuck machine that can keep up is important. Next, how big and long does your new thruster need to be? It is important to select attachments that can be used comfortably while still fulfilling your desires. Lastly, consider your budget. Some thrusters may be purchased for $50 or less, while premium thrusting dildos may be a larger investment.

Various Types of Thrusters and Thrusting Sex Machines & Toys

Luckily, there are many kinds of thrusting sex machines to choose from. Some of the more popular thrusting adult toys include:

Automatic Sex Machine

Automatic sex machines rose in popularity through adult films. The machine includes a penis-like attachment that thrusts in and out at varying speeds. Select automatic sex machines may also include a vagina-like attachment, into which a penis may be inserted, simulating the sensation of vaginal intercourse. Automatic sex machines include a frame, saddle, box or stand. During use, the user can use the toy in the doggy position, on their back, or may mount the machine and ride cowgirl style.

Manual Sex Machine

Manual sex machines are the perfect option for those who want to move at a gentler pace. Manual sex machines include a penis-like attachment that can glide or rock. The dildo moves in and out of the body based on the user’s movements, giving them full control of the power and speed of the thrusts.

Ride-on-Top Sex Toy

Ride-on-top thrusters include a saddle-style chair or bench design plus a penis or finger-like attachment. The rider mounts the seat and inserts the dildo into their body. Many ride-on-top vibrators and sex machines can rotate, vibrate, and thrust to bring the rider to orgasm.

Handheld Thrusting Dildos

Handheld thrusting dildos are budget-friendly and practical options for those who crave a filling sensation. The thrusting dildo is a compact device that can be used manually. Some models include a suction base that can be mounted in the shower or on a flat surface. Thrusting dildos give the user the power to control the speed, stroke, or thrusts, providing a custom experience every time.

Adding a thrusting sex machine to your routine adds new excitement and possibilities. Whether you buy an automatic sex machine, manual sex machine, ride-on-top toy, or thrusting dildo, you will surely enjoy a satisfying, penetrative experience. A thrusting sex machine will never get tired of giving you orgasms whenever the mood strikes. That’s why you need to give The Motorbunny Buck a whirl!
