Double Penetration Attachment for Motorbunny: Fit and Setup

Quick answer

Fit the Double Penetration attachment by aligning its base with the Motorbunny Original's main shaft mount, then tighten it fully before use. Check that both the 5-inch main shaft and 3-inch rear plug sit straight, and apply water-based lubricant to the silicone before riding.

Step-by-step fit and setup

1. Inspect the attachment and machine mount: Before attaching, check the silicone for tears or residue and confirm the Motorbunny Original's mount is clean and dry. A common mistake is skipping this check and trapping debris under the base. Wipe both surfaces with a damp cloth and let them dry completely before mounting.
2. Align and seat the attachment: Line up the base of the Double Penetration attachment with the machine's main shaft mount and press it down firmly until it sits flush. Do not force it at an angle; the base should seat evenly. If it rocks or lifts at one edge, remove it and realign rather than tightening through resistance.
3. Secure the attachment: Tighten the retaining ring or collar according to your Motorbunny Original's instructions until the attachment cannot twist by hand. A common mistake is leaving it loose, which can cause wobble during rotation. Give the attachment a gentle tug; it should not move independently of the machine.
4. Check clearance and angle: With the machine off, confirm the rear plug points downward or slightly back, depending on your riding position, and that neither shaft contacts the machine body. Adjust your position or the machine angle before turning it on. Test the full range of motion with the power off so you know the attachment will not bind.
5. Apply lubricant: Apply a generous layer of water-based lubricant to both the main shaft and the rear plug, and add a little to yourself. Silicone attachments can feel draggy with too little lubricant, and oil-based or silicone-based lubes can degrade silicone over time. Keep lubricant within reach; reapply as needed rather than pushing through dryness.
6. Start on the lowest setting: Turn on the Motorbunny Original at its lowest rotation and vibration setting, then position yourself slowly. The rear plug is tapered for easier insertion, but the main shaft is 5 inches around, so take your time. If either shaft feels uncomfortable, stop and adjust your angle before increasing power.
7. Clean and store after use: Remove the attachment, wash it with warm water and mild soap or a silicone-safe toy cleaner, and dry it completely before storing. Because the silicone is non-porous, it can be sterilized, but avoid abrasive scrubbers that can scratch the surface. Store it separately from TPE or jelly toys to prevent material interaction.

Product facts

• Premium Silicone Double Penetration Attachment: Made of 100% non-porous silicone and compatible with the Motorbunny Original. Non-porous silicone can be sterilized and is less likely to harbor bacteria, but it also means the attachment is firm and should be paired with water-based lubricant.
