How to Use the Motorbunny Grip Attachment with Vac-U-Lock Dildos: A Compatibility Guide

Learn whether the Motorbunny Grip works with Vac-U-Lock dildos, how to set it up, and which attachment system suits your ride.

Quick answer

The Motorbunny Grip is not designed to hold Vac-U-Lock dildos. It is built specifically for Doc Johnson Main Squeeze strokers. To use Vac-U-Lock dildos with your Motorbunny, you need the Motorbunny Vac-U-Lock Adapter, which lets you attach any compatible Vac-U-Lock dong directly to the machine.

If you own a Motorbunny, you've probably wondered whether you can mix and match attachment systems. The Motorbunny Grip looks versatile, but it's designed for a specific type of toy. Meanwhile, Vac-U-Lock dildos offer a huge range of shapes and sizes. Understanding the difference saves you time and money.

This guide explains why the Grip and Vac-U-Lock are not interchangeable, how to set up each system, and how to decide which one fits your riding style.

Why the Motorbunny Grip and Vac-U-Lock Are Different Systems

The Motorbunny Grip is a specialized attachment that holds Doc Johnson Main Squeeze strokers. It uses a pull-tab locking lever to secure the stroker in place, allowing hands-free vibration and thrusting. It is not designed to hold Vac-U-Lock dildos, which use a different mounting mechanism.

Vac-U-Lock dildos have a hole in the base that fits onto a Vac-U-Lock adapter. The Motorbunny Original Vac-U-Lock Adapter attaches to the machine's post, letting you swap in any compatible Vac-U-Lock dong. These two systems are not cross-compatible without additional parts.

  • Check the base of your attachment: a hole indicates Vac-U-Lock, a flat base with a locking slot is for the Grip.

How to Use the Motorbunny Grip with Main Squeeze Strokers

If you want to use the Grip, you need a Doc Johnson Main Squeeze stroker. The Grip is designed to firmly support these strokers, so you can enjoy hands-free vibration and thrusting. Mounting the Grip is simple: slide the stroker into the Grip and use the pull-tab locking lever to secure it.

Make sure the stroker is inserted fully and the lever clicks into place. A common mistake is not locking the lever properly, which can cause the stroker to slip during use. Check the fit before you start and re-tighten if needed.

  • Always inspect the Grip and stroker for wear before each use.

How to Use Vac-U-Lock Dildos with Your Motorbunny

To use Vac-U-Lock dildos, you need the Motorbunny Original Vac-U-Lock Adapter. Attach the adapter to the Motorbunny's post, then push the Vac-U-Lock dildo onto the adapter until it clicks into place. The adapter gives you complete control over the size, texture, material, and shape of your penetrative ride.

One common mistake is not pushing the dildo firmly enough onto the adapter, which can cause it to detach mid-ride. Always test the connection before use. Also, make sure the dildo is clean and dry before attaching to avoid slippage.

  • Keep a few compatible Vac-U-Lock dildos on hand to switch up sensations quickly.

Which Attachment System Should You Choose?

Your choice depends on the type of stimulation you want. The Grip is ideal for stroker users who want a snug, hands-free experience with a Main Squeeze stroker. Vac-U-Lock is better if you prefer a wide variety of dildo shapes, sizes, and textures, including realistic options like the Vac-U-Lock 8 Inch ULTRASKYN Cock.

Consider the Motorbunny BUCK Vac-U-Lock Edition if you want both thrusting and Vac-U-Lock compatibility out of the box. It includes a Vac-U-Lock adapter and two attachments, so you can start riding immediately. If you already own a Motorbunny Original, the standalone adapter is an affordable upgrade.

  • Think about your preferred sensations: strokers offer internal texture, while dildos offer girth and length variety.

Step-by-Step: Using Vac-U-Lock Dildos with Your Motorbunny

  1. Gather your equipment: You'll need your Motorbunny machine, a Vac-U-Lock adapter, and a compatible Vac-U-Lock dildo. Ensure all parts are clean and dry. Checkpoint: Verify the dildo has a hole in the base for Vac-U-Lock compatibility.
  2. Attach the Vac-U-Lock adapter: Slide the adapter onto the Motorbunny's post until it fits snugly. Make sure it's fully seated to prevent wobble. Common mistake: Not pushing the adapter all the way on can cause instability.
  3. Mount the Vac-U-Lock dildo: Align the hole in the dildo's base with the adapter and push firmly until it clicks into place. Give it a gentle tug to confirm it's secure. Checkpoint: If the dildo rotates easily, it may not be fully locked.
  4. Test before riding: Turn on the Motorbunny at a low setting to check for any slippage or unusual movement. Adjust speed gradually. Common mistake: Starting at high speed can cause the dildo to detach if not properly secured.
  5. Ride and adjust: Position yourself comfortably over the dildo. Use your hands to guide it if needed. Adjust the machine's angle or speed to find what feels best. Remember to stop and re-check the connection if you feel any looseness.
