Get a rain coat

I purchased this on a whim, for a surprise for my wife. She’s adventurous but not an exhibitionist so I wasn’t sure what she would think. I read about he 45 day guarantee, and I figured if it didn’t work out I wasn’t out too much money and if it lived up to the hype then it would be worth every penny. Needless to say, we will not be returning it. My wife and I found a great position where she can ride using the flat attachment and I can take her from behind. I’ve never felt her so wet. She can be in total control of the pressure and speed and I can do my thing hitting her g spot. She can build the orgasm and take it slow or cum in a matter of minute(s). The attachments are also great. Lots of different sizes and styles. If you’re on the fence just get it. If she’s not into it then send it back, but if she is into it….buckle up and get a rain coat.

Exceeded expectations!

Bought the Buck as a surprise for my wife a few weeks ago. Shipped and arrived very so quickly I had to have my 15 y/o kid hide the boxes in the garage. (Also got the hard case) Thankfully, the packaging was very discreet so there was no awkward questions. I spent about 40 minutes unpacking and assembling, ran a quick test of functionality, and repacked in the carrying case.

Fast forward... the kids had an unexpected sleepover last weekend. I worked up the courage to present her with the most expensive sex toy I've ever imagined. I dragged the case out and presented it. As I pulled it all out and assembled it, I explained all the functions while she read a bit about it. She was very intrigued but equally intimidated. Now, we are not at all beginners when it comes to toys, but none of our playtime tools weigh this much nor plug into a wall outlet.

Fast forward again...
We attach the flat grinding attachment and she straddles it. I turn the buzz to 1 and immediately she understands this is a little different. I run it slowly up to 11 and back down quickly. She looks at me and says something like "this is something."

That was the last time I saw anything other than the whites of her eyes for about 45 minutes due to rolling back in her head as we proceeded to try out the full functionality of this beast. It was all that I had hoped and more. I got so turned on controlling her pleasure that during one of several breaks I had to give her the old tried and true. That pushed her over a few more times, then back on for a few more.

To wrap this up, the wife didn't tell me how many big O's she had, but I'm positive she lost track. One word of warning though...she wound up not being able to walk properly for a couple days due to her leg muscles being sore from all the convulsions. She made sure I knew that it was not an internal pain whatsoever. It was like working out too hard. Beyond that, she had a hard time keeping her freaky side in check for a few days too and I've got a ton of dirty talking texts and pics to prove it.

Hands down best thing that's happened for our sex life since we were sex crazed teens!

Fantastic Scene!

She had more orgasms and linked orgasms than she ever experienced before. And sitting back wat hing her as I enjoyed a cocktail was magical. VERY pleased with rhe investment.

Orgasmic fun!

By far best on market. We actually chose after having tried all.

It is super easy to clean and has extra padding when you squeeze those thighs from pleasure.

Its size is perfect for personal play and incorporating play with your partner while using external vibration. We look forward to exploring all the possibilities!

We proudly display our buck and our motorbunny in our bedroom.

However, if you have small kids at home the travel case can hide it away.

I never heard her make the noises she made following use of the buck. She even begs to use it more and more. 5 stars

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!
