How to Use a Vac-U-Lock Dildo with Your Motorbunny: Setup, Positioning, and Safety Tips

Quick answer

Attach a Vac-U-Lock-compatible dildo by pressing its hole onto the Motorbunny's Vac-U-Lock adapter until it clicks. Then secure it with the included locking ring or zip tie for extra hold. Position yourself over the machine, adjust the height and angle, and start with slow speeds to find your comfort zone.

You just got a new Vac-U-Lock dildo and want to use it with your Motorbunny. The setup is straightforward, but doing it right makes the difference between a smooth ride and an interrupted session. This guide walks you through the full process—from attaching the dildo to positioning your body—so you can focus on the sensation, not the mechanics.

Motorbunny machines are known for their powerful vibrations and thrusting action, and the Vac-U-Lock system lets you swap dildos quickly and securely. Whether you're using the Signature Cocks Alex Jones model or another Vac-U-Lock-compatible dildo, these steps apply to every setup.

Before You Start: Check Compatibility

First, confirm your Motorbunny model has a Vac-U-Lock adapter. The Original and BUCK models typically include or support this adapter, but check your manual if you're unsure. The dildo itself must have a Vac-U-Lock hole—a suction-style indentation at the base. Most high-quality dildos, including the Signature Cocks line, feature this.

If your dildo doesn't have a Vac-U-Lock hole, you can't use it directly with the Vac-U-Lock system. You'd need a different adapter or a non-Vac-U-Lock attachment. This guide assumes you're using a Vac-U-Lock-compatible dildo.

• Check your Motorbunny's manual or product page to confirm Vac-U-Lock compatibility.
• Inspect the dildo's base for a clean, unobstructed hole.

Attach the Dildo to the Adapter

Align the Vac-U-Lock hole on the dildo with the adapter's protruding tip. Press firmly and evenly until you feel a click or the dildo sits snugly against the adapter. The fit should be tight—no wobbling or slipping.

Most Motorbunny setups include a locking ring that slides over the base of the dildo to secure it further. If you have one, use it. If not, a zip tie around the base is a common workaround, but check that it doesn't interfere with the machine's movement.

• Push the dildo straight, not at an angle, to avoid damage to the adapter.
• If the dildo slides on too easily, it might be the wrong size—it should require firm pressure.

Position the Machine and Yourself

Set the Motorbunny on a stable, non-slip surface. Adjust the machine's height so the dildo enters you at a comfortable angle. If you're riding in a squatting position, the machine should be slightly lower than your hips. For a hands-free position, use pillows or a wedge to support your back or knees.

The angle of the dildo matters. Tilting it forward or backward changes G-spot or P-spot stimulation. Start with a neutral, straight-up angle and experiment with subtle adjustments once you're comfortable.

• Place a towel or mat under the machine to prevent slipping and to catch any lube drip.
• Keep a bottle of water-based lube within reach.

Use Plenty of Lubricant

Water-based lube is essential, especially with silicone dildos. Silicone-on-silicone can damage the surface, so never use silicone lube with a silicone dildo and a silicone attachment. Apply lube generously to both the dildo and yourself.

The Motorbunny's powerful thrusts can dry things out quickly, so reapply as needed. A lube launcher or a squirt bottle makes this easier without stopping the session.

• Always choose water-based lube for silicone toys.
• Reapply every 10-15 minutes, or whenever you feel friction.

Safety Checkpoints During Use

Listen to your body. The Motorbunny can go very fast, and without careful adjustment, you could experience soreness. Start at the lowest speed and gradually increase. If you feel any sharp pain, stop immediately.

Keep a hand on the machine's base or emergency stop button. If you're using a hands-free setup, ensure you can easily reach the stop controls. Also, don't leave the machine running unattended—even for a moment.

• Always use the machine with a partner nearby or a safety word if you're alone and feeling adventurous.
• Never force the dildo deeper than feels comfortable; let your body guide the depth.

Step-by-Step Setup and Positioning Guide

1. Gather Your Supplies: Have your Motorbunny, Vac-U-Lock adapter, dildo, water-based lube, and a locking ring or zip tie ready. Checkpoint: Ensure all parts are clean and free of lube residue before starting.
2. Attach the Adapter: If your Motorbunny doesn't have a built-in Vac-U-Lock adapter, screw or snap it onto the machine's rod securely. Verify the adapter is firmly attached; a loose adapter can cause the dildo to slip.
3. Mount the Dildo: Press the dildo's Vac-U-Lock hole onto the adapter tip until it clicks. Use a locking ring or zip tie for extra security. Checkpoint: Tug gently on the dildo to confirm it's secure—it should not move independently.
4. Position the Machine: Place the Motorbunny on a stable surface and adjust its height so the dildo aligns with your body. Consider using pillows for support. Checkpoint: Sit on the dildo without turning on the machine to test the angle.
5. Lube Everything: Apply a generous amount of water-based lube to the dildo and your entrance. Reapply during the session as needed. Avoid silicone lube with silicone toys to prevent damage.
6. Start Slow and Adjust: Turn on the machine at the lowest speed. Gradually increase intensity while adjusting your body position to find what feels best. Checkpoint: Keep a hand on the stop button; if you feel pain, stop immediately and reassess.
