Quick answer
The Motorbunny Buck Mt. Gushmore flat attachment is designed for non-penetrative grinding with a sloped, ridged surface that focuses vibration on the clitoris. Use the steps below to attach, use, and clean it properly.
Why choose a flat attachment for your sex machine
Unlike traditional penetrative attachments, the Mt. Gushmore sits flat on the Motorbunny Buck's thrusting arm. Its sloped shape and cascading ridges create multiple points of contact for clitoral stimulation without insertion. This makes it ideal for users who prefer grinding over thrusting or want a break from internal play.
The 100% non-porous silicone material is easy to sterilize, but note that returns are not accepted for attachments, so confirm compatibility before purchase.
How to use the Mt. Gushmore attachment on your Motorbunny Buck
- Attach the Mt. Gushmore to the Buck: Remove any existing attachment from your Motorbunny Buck. Align the base of the Mt. Gushmore with the Buck's attachment hub and press firmly until it clicks or seats fully. The silicone base should sit flush against the machine arm. A loose fit means the attachment isn't fully seated; recheck alignment before use.
- Choose your grinding position: Lie on your back or lean over the machine so the flat, sloped surface of the attachment contacts your vulva. The 7 cm peak gives you a natural slope to rock against. Adjust the Buck's thrusting speed to a comfortable level—start low and increase gradually. If the ridges feel too intense, place a thin towel over the attachment to soften the texture.
- Clean and store after each use: Remove the Mt. Gushmore from the Buck. Wash with warm water and mild soap or a toy cleaner. Because it's non-porous silicone, you can also boil it for 3 minutes or wipe with a 10% bleach solution for sterilization. Dry completely before storing in a cool, dry place away from direct sunlight. Avoid sharing this attachment without sterilization between users to prevent cross-contamination.
